I have a little project in mind, but would like some input from the pros to cut research time:
Is it possible to "wrap" a Today plugin dll with another, providing a "pass through" for operations (such as screen taps, etc)?
What I'm trying to accomplish is this: Add selectability and other one-handed d-pad operation to an older plugin that is not selectable.
What do you think?
it's possible but the problem is that the plugin have to keep track on what plugins it include and which handles it have to pass to them
could end up big and slow

This is specific to a single plugin - it would only keep track of one.
Perhaps plan B would be easier - a plugin that manipulates another plugin. Such that it would "appear" the older plugin was selected, etc. I guess I'd better go study some more...
Actually its really simple.
Any plug-in DLL exports a function called InitCustomItem. In this function the plug-in does all its initialization, and creates its window. The return value is the handle to this window which you can subclass to add functionality.
as for selection, there is a value in the registry for each plug-in (HKLM\Software\Microsoft\Today\Items) which controls whether the system passes selection events to the plug-in or not.
it has three settings:
0 - non selectable, item will be skipped by the system.
1 - Automatic, the system will paint the item and handle selection on / off
2 - Manual, the system will pass the selection event to the item and the item will take care of the rest. In this mode the return value of the WM_ACTION determines whether the selection is moving on. This is good for multiline plug-ins that don't want to give up focus when arrow keys are pressed.

Hey, thanks for the response! I've set the Selectability registry item for the older plugin, and it's ignoring it - that's what started me on this little project.
I'm a software developer by trade, but not with C++, so I don't want to waste people's time here asking a lot of dumb questions. If you could point me in the right direction on a couple of things, I'll go off and learn:
1. If all I have is a dll and nothing else (no .defs, etc), can I determine all of the functions it exports (other than InitCustomItem)?
2. Process check: My custom plugin's InitCustomItem would call old-plugin's InitCustomItem, snagging old-plug's hwnd. New-plugin would then initialize it's own window - transparent(?) and pass that hwnd back to windows. Also, my custom plugin would pass all messages to old-plugin, etc. Theoretically, old-plug would look and operate like normal?
If this is already written, just sent me the code!
Well I am afraid it will be difficult to do all this without C++. As far as WM based devices are concerned you need to use something that translates in to native code to create system components like the plugins son ,no .NET languages, and embedded VB doesn't do well on anything never that WM 2003 (not even SE), plus I am not sure if you can make DLLs with it at all.
To your questions:
1) There is a tool which comes with VS 6 called Dependency Walker. It shows you what functions a given DLL exports, what it imports from other DLLs and what DLLs it is link to. Woks on EXE files as well.
If you can't get that, download a demo of IDA 5. It's the most powerful disassembler for WM devices out there.
2) Not sure, I never tried anything like that. The thing is, the system resizes the plugins, on initialization (it controls height) and when screen rotation changes so if you pass back HWND for a window other than the one visible, it might cause some problems.
I think what you should do is learn about subclassing. It's when you replace the procedure of an existing window with your own (just replace the function, not create new window). You then get all the messages for that window, you can do what you want and call the original function when you done.
By the way, if you want to learn about writing plugins there is an article with code samples on this site: www.pocketpcdn.com and a lot of other interesting stuff.
Good luck.
What plugin is it? It might be easiest just to rewrite the plugin if you've got the code.

I don't have the old-plugin source code. My little project is to add some sort of d-pad operation to the WeatherPanel plugin, which you're probably familiar with.
Progress: I've written and deployed my first little plugin - based on the source code samples available in the internet.
Next step: In my InitializeCustomItem, I thought I'd try to call WeatherPanel's InitializeCustomItem (instead of creating my own window). Thing is, I don't yet know how to properly link the WeatherPanel dll to my project. As expected, it only exports two functions: InitializeCustomItem and CustomItemOptionsDlgProc (I used dumpbin.exe)
I'll keep plugging away - any input would be appreciated.
Thanks for your help!
It's real easy:
Use LoadLibrary and GetProcAddress functions to call functions in other DLLs without linking them.

What a coincidence! My studying led me to the same functions.
From within my plugin's InitializeCustomItem, I was able to successfully load the dll with LoadLibrayl, GepProcAddress of its InitializeCustomeItem (at ordinal 240) and call it. But it whacks the Today screen so that none of the plugins load.
Next I thought I'd try FindWindow and EnumChildWindows to find it and all it's children. Then manipulate them by sending messages...

Update: So far, so good. As it turns out, EnumChildWindows doesn't work on the PPC, so I used GetWindow to find the plugin's handle. I can successfully send messages to it and initiate various actions.
Question: I'd like to visually indicate (on the old-plugin) what's being clicked (such as drawing a box around it). Is it possible to draw things outside of my own window?
It is, but it's tricky.
You can always use the GetDC function to retrieve the DC for another window and paint on it, but the problem is that unless you subclass the window you have no way of knowing when it repaints it self and all your changes are erased.

I tried that exact thing (GetDC) and drew a rectangle in it, but it didn't do anything. I realized the reason was the WM_Paint event wasn't firing on old-plugin, and when it did, my stuff was erased (just like you said).
Next idea - open my own dialog window than overlays old-plug. The entire window needs to be transparent - except for the visual indicators that I position where I want. When the user ok's, I close the window and send the click to old-plugin...
Thanks again for keeping tabs on my progress..
No offence, but with all these rather advanced programming tricks you are attempting just to "sup up" an old weather plugin it looks to me like you would be better off just writing the whole thing from scratch.
It you are familiar with WinInet and / or sockets this should be pretty easy and it will look and work much better than the hack you are attempting now.
Plus you can make it exactly the way you like.

No offence taken. I thought of that, but I figured this would be a good way to cut my teeth a little. Once I complete this little project, I may pursue that route...
Question: Do you have a favorite forum (or forums) besides this site that you use for your research/programming questions?
This is my favorite forum
But here are couple more sites I found very valuable:
www.pocketpcdn.com - They have tips and tricks with code examples arranged in categories like how to make MFC dialogs not full screen or the one I used in LVMTime to put the clock back on the taskbar.
www.codeproject.com - It's not specific to WM development but has tons of interesting stuff including entire sources.
You should also check out www.buzdev.net If you're not familiar with the great work of buzz_lightyear you should see some of the stuff he did for this forum like grab_it - the invisible ROM dumper.
OT
Just a quick OT question:
If I would move some of the plugin-dll's from \Windows to \Storage Card, would it be enough to change the adress within the corresponding item in the registry entry HKLM/Software/Microsoft/Today/Items ?
Of course I'm not talking about plugins like tasks a.s.o but rather third party plugins
Cheers
hrb
It won't work.
The problem is that the SD card is mounted too late so if you put the plugins on it they will not be loaded when device boots up.
You can move them to the extended ROM this way or to a folder other than windows but there is no way to move start-up stuff to SD.
Thanks for the help with this "little" project. After many hours, the product is out for beta testing. When it's released, I'll post more info...
Finished!
It's finished. The app is called WP-Pilot and it provides one-handed operation of WeatherPanel. If anyone's interested, it can be found here. Here's how it ended up:
There's a plugin (WP-PilotPlugin.dll) with an options dialog, and an executable (WP-Pilot.exe).
When the plugin gets selected, it looks for Weatherpanel. If it finds it, it fires off WP-Pilot.exe
WP-Pilot.exe opens. It does this stuff:
Look for WeatherPanel, and get it's screen coordinates.
Read the registry and determine which layout file WeatherPanel is using.
Open the layout file and read it: Record the coordinates of each "clickable" item found. This was a real PITA because of Unicode.
Sort the coordinates for left-to-right, top-to-bottom order.
Select the first coordinate and position a tiny window (10x10) at that x-y position.
Draw a "pointer" in the window (the type and color depends on what's selected in the options).
Show the window and process input:
[*]Left/right pressed - selected the next/previous coordinate and move the window to that location.
[*]Up/down pressed - close WP-Pilot and tell the plugin we're done.
[*]Center button pushed:
[*]Send a mouse click to the WeatherPanel plugin at the coordinates
[*]Close WP-Pilot and tell the plugin we're done.
Thanks again for your help!
Ok, most of you may find this totally useless as a plugin, but it was a combination of a request by user Treo_newb and a desire to create a sample plugin project that could be used as a base / example for plugin writers (I plan on doing an article on codeproject.com and this will be the source for it).
What does it do?
This plugin displays a string stored in registry.
The path is:
HKEY_CURRENT_USER\Software\RegDispPlugin
Value name: DisplayString
It checks if this string has changed several times per second when today screen is shown (as the system sends refresh message to all plugins) and displays the updated message if a change occurred.
What is it good for?
First, if you write apps using mortscript or similar like the user who requested this it will let your script display stuff on today screen.
Alternatively it could be used to mark your device today with a string that isn't as easily changed as user info.
The source is basically a skeleton plugin you can use to build your own plugin on (no license / copyright to limit you) and it already has several tricks needed for the plugin to display correctly:
VGA compatibility
Text size matching system settings
Proper header in settings dialog (like on system plugins)
Proper text color when selected (according to theme)
No blinking all today screen on change
Proper resize when switching between landscape and portrait
When I was writing my first plugin I could not find all these little fixes concentrated in a single article so I had to fish for each one as the bug reports came in.
Hope you will find this little project useful.

The source (eVC 4 project): View attachment RegDisplay.zip
Thanks for this!
Thank You Lev.
Thanks, Thanks, Thanks,
You are a legend.
I was almost through with my today plugin and was trying to figure out reading registry values and all of a sudden I get a PM from u about the plugin !!!
Very Cool !!!
OK a few questions,
1. I know that WM_TODAYCUSTOM_QUERYREFRESHCACHE is called for refreshing the today plugin, any ideas about when is it called.
I read somewhere that it was 2 seconds. Is it true?
2. I saw ur code and u have exposed CustomItemOptionsDlgProc in RegDisplay.def, but when I installed the cab file the 'options' is not enabled.
I manually changed the resistry and changed options to dword = 1 and saw ur name and email address.
u might want to enable that by default so that people can notice ur work.
I am planing a commercial release of a new project on basis of this.
Thanks again,
Shailesh
First, you're welcome.
shaileshashar:
1) I ran a debug print on this message once on an iPaq 1710 and it seems to be sent several times per second. This could differ from OS to OS or even from device to device, I am not sure.
If you need specifically timed refresh, or you have an event triggered on new data, I suggest using a timer or maybe a thread that will wait on an event. You can refresh your plugin from anywhere in code by calling InvalidateRect with your window handle.
2) I messed up the cab at first, forgetting to add the Options reg value. Then when I went to upload the fix, I couldn't access the site for about an hour (no idea why, I even rebooted the PC to Ubuntu). Should be fixed now, but I will check it later again (I have to go back to XP for that).
Good luck with your program.

Thanks for the help, will check the fixed cab.
Also a suggestion:
A custom icon could also be incorporated. You can give a option to load a custom icon next to the text in the today plugin.
I know anybody can modify ur code and do it but still.
Actually, I probably should have mentioned this in the original post but I have no intention of adding options to this thing.
This would only complicate the code and turn it in to an actual app instead of a sample project.
But by all means feel free to make suggestions. If this thing does become popular, when I am done with my other projects (like LVMTopBat) which won't be any time soon (unfortunately) I will release a separate version of this plugin with all kinds of options that can be controlled both by user (form the options dialog) and by other apps through registry.
Maybe things like text alignment, size, bold / Italic / underlined.
P.S.
The reason I put the string this plugin loads under HKEY_CURRENT_USER instead of the HKLM where the rest of the plugin registry resides is because by default the HKEY_LOCAL_MACHINE on WM 5 and higher has a security restriction. For example you can not write to it using RAPI, only by authorized (or signed) app on the device. The HKEY_CURRENT_USER on the other hand is open for all.

As a frequent mortscript user I think, this great app might be even more usefull, if the string was shown in an "allways on top" message box instead of the today screen. The Today screen might be obscured by other active windows during the scripts runtime and the plugin eats precious today screen estate also while being unused, doesn't it?
In that case (of a standalone application) I would furthermore introduce some kind of termination string (or reg. value) to end the display application.
Code:
- start mortscript
- writes first string to registry
- starts display application (run)
- updates string in registry whenever appropriate
- ...
- writes termination string to registry
-> display applications self-terminates
- ...
- end of mortscript
Honestly, I already do use something comparable with mortscript (employing a conditioned sleepmessage loop and reading from the registry too), but this could be much nicer and more elegant.
Just my 2 cents... What do you think?
I think something like that would be better implemented by the mortsrit program it self.
It could be a function like MessageBox API in windows which you could then command on and off. Having it built in would save precious resources on the device that would be wasted by having an extra app run constantly in background.
This is just my thought though.
I'd suggest contacting the developer of mortscript and discussing it with him.

Mort knew about that request and by chance just announced to so.
Thanks anyway.
Hello levenum,
I just joined the community. Reason being, I found your RegDisplay plug-in
You call it a sample project, but the impact is that of an awesome solution.
Great for MortScript, but equally useful in BASIC applications that write
messages to the registry which is show upon screen minimization.
I regret not being a C programmer (mainly BASIC), else I'd love to further
develop this jewel.
Your plug-in runs flawlessly in an iPAQ 210 under WM6 Classic.
Cheers and Respectful Greetings

CLSID for registry display plugin
What is the CLSID for the Registry Display Plugin? I am going to have to edit the XML file that defines my home screen in order to get the plugin to show up. I am using Facade to control my home screen, and the only plugins that it will show in its list are those currently in use in one of the XML files in the Application Data\Home folder. All other new plugins require editing the XML. Thanks for your help.

This is great! I was asked if I could write a today screen plug-in for my weather application (http://forum.xda-developers.com/showthread.php?t=445576) - I couldn't since I don't have the skills and I'm writing .NET code - but this is exactly what I needed.
I'm adding support for this plug-in and will of course give credits to you.
I am interested in dabbling a little in programming for my Kaiser. I have programming experience, mainly php / mysql, though I have done some C and lots of scripting in my time.

All the stuff I want to do is today screen plugins - was thinking of having a bash at writing my own quick contacts plugin - *very* basic - just a vertically scrolling list of names over a transparent PNG button with maybe photos from the address book - I want it to be able to scroll by vertical gesture within an ultimatelaunch tab - is this likely to be quite easy and quite a good "first app" to program?
I was also looking at writing a lite repacement for phoneweaver as the only feature I use is to turn on BT when it detects power but no activesync (ie auto turn on BlueTooth when I am in the car and the device is cradled) - maybe a hack to force the keyboard backlight on in the same situation.

Thanks rud. I was aware of various other posts, but my question was more of a "How steep is the learning curve?" rather than "How do you do it?".
There was also an element of "How do you do it?" insofar as there seem to be better or worse ways of going about various kinds of app (eg today apps with gesture support) which I am finding a bit of a minefield, but I feel that the new post was valid because I am giving an indication of my experience level and what I am trying to acheive - none of the posts you listed cover the combination of stuff I am trying to do. Reqs like pulling from outlook db and allowing gesture scrolling in a today plugin, I dunno, I may waste ages with C#, for example, only to realise it is a breeze with C++... I also note that a google search for wm programming gesture scroll today screen currently ranks this very thread #5. By tomorrow that'll be a googlewhack then.
Yes, there are various posts about how to get started, but I think maybe a sticky would be in order with a bit of info on the various paths - the vb/c++/c# options are quite bewildering - stuff like

Your question is mainly a matter of personal preference.
Here is my opinion on C++ vs. C#:
C++ advantages:
- Native code is faster than .NET
- Easier access to Win32 APIs
- Ability to write system components like keyboards and today plugins.
C# advantages:
- Saves on coding time
- Allows use of many .NET CF components to quickly accomplish complex tasks.
Please note that I am bias. I hate .NET and want nothing to o with it. Specially on mobile devices that do not have the processing power to spare for the .NET overhead.

Hey!
Congrats on getting your hands on with Windows Mobile...
The easiest way is to download Visual Studio 2005(2008 You have it on MSDN) - and create a new application with it.
It's sooo easy if you know your object oriented programming, as long as you want to create ordinary "office" applications... But if you want to do more advanced things(like creating a today-plugin) you need to go over to c++(even though you can download a .net home-plugin-container which acts like a "loader" for your plugin written in c++) - and also, if you want to create good GUIs, I think you are better off with c++... But then again, I think you need a bit more effort in learning c++ then using c#...
Hope this helps...
Still slogging my way thru this...
I got hold of an MSDN disc, first off I installed visual studio 6 - bad move.
Had to uninstall before trying to install VS 2005, now I think it has screwed something up, every time I try and create a "Smart Device Win32" project, I get a "Project creation failed" error. I may have to re-GHOST my OS to get rid of it
So much time just finding out what apps I need and what options to choose to start a project...
I found http://channel9.msdn.com/wiki/default.aspx/MobileDeveloper.HomePage which seems helpful
Thanks for responses!
Evilc, you link of msdn is excellent point, many thanks!
I have also just started programming in C++ ..i dnt have any knowledge of any type of codes..i learned every thing frm MSDN libraries ( i have many many of them caz i have VS 2006 VS 2005 and VS 2008 )..i recommend you to work with C++ because it uses less system resources and is fast..hope this helps..check out my Kitchen coded in C++ ( link in signature )
Yeah, I think C++ is definately more what I am looking for from what I have learned thus far.
Re-Ghosted OS - totally fresh XP SP2, installed Visual Studio 2005, still the same error. GRRR!
Visual C++ --> Smart Device --> Win32 Smart Device Project == "Project Creation Failed"
Other Languages --> Visual C# --> Smart Device --> Windows CE 5.0 --> Device Application == Project created OK.
Some posts I have found on the net say it is an IE7 issue, I may try uninstalling that or flashing back to an OS image with IE6 only, but this is really winding me up and taking a *lot* of my time...
I uninstalled IE7 and the problem went away. Woohoo!!
starting programming windows mobile
hello
1. see my web site.
2. see my book recommendations, especially the 'programming windows ce' by douglas boling. It has an example for many things and a today sample too. Most is based on visual c++ 3.0/4.0. Embedded Visual C 4 can be loaded free of charge at ms.
regards
josef
Nice site, thanks.
The windows mobile 6 sdk actually has a today screen sample, along with samples of most of the things I need to do.

It's sooo easy if you know your object oriented programming, as long as you want to create ordinary "office" applications... But if you want to do more advanced things(like creating a today-plugin) you need to go over to c++(even though you can download a .net home-plugin-container which acts like a "loader" for your plugin written in c++) - and also, if you want to create good GUIs, I think you are better off with c++... But then again, I think you need a bit more effort in learning c++ then using c#...
Hope this helps...

Are we using the same language?? Cos this (C++ Win32 for Mobile Devices) is by far and above the most difficult programming language to get into that I have ever tried. Yes, worse than ASM.
Trying to code an app that prints "Hello World" has taken me over 5 hours with no success yet - most languages I have a go at it's 5 minutes.
From http://msdn2.microsoft.com/en-us/library/ms901121.aspx :
Code:
int DrawText(
HDC hDC,
LPCTSTR lpString,
int nCount,
LPRECT lpRect,
UNIT uFormat
);
It gives a brief description of what the parameters are, but absolutely no examples and no explanation of what all the parameters do or how to initialize them, so even browsing an example is no use to me.
u can simply try
MessageBox::Show(" your message ");

Isn't that .NET ?
I thought the consensus was that Native Win32 or whatever it is called was the better way to go?
This is part of the problem. I cannot even work out what to put in a search engine to pull out info on the right "flavour" of C and for the pocketpc. It's *so* bewildering.
Hello evilc.
First I noticed you have some trouble with VS 2005. It probably won't be easy now, but if you ever get to format your machine again don't install it (unless you absolutely need some other features).
For C / C++ programming for WM device I strongly recommend eVC 4 as it is much lighter and responds quicker. (It's a free download as well)
Second, though you can program for WM in C# and VB .NET which are both .NET Object based languages and are probably much closer in form to PHP and Java then C, you can not write system components such as today plugins in those languages.
You need native code so C / C++ is the only way to go.
(Actually, there is a trick to combine C# and C++ DLLs to create a today plugin where C# will do the main stuff, but its pretty complicated)
What you need is to learn basic Win32 programming and using the windows API. They are almost identical for Windows Mobile and Desktop windows versions so any book on Win32 should teach you the basics.
(Personally I started with MS book on MFC and studio 6 but I would not recommend it)
Finally:
I would gladly explain the parameters of DrawText but I am not quite clear on how much familiarity you have with the Win32 mechanics, since the languages you are used to obscure them unlike C which gives you extra power but also makes you work much harder to get anything done.
Do you know how to handle messages, and how windows manages all abjects using handles? Any familiarity with GDI?
If not, it will be pretty difficult to explain.

I tracked down the problem when I got home and installed on my desktop. When doing it on the laptop, whilst installing SP1 for studio 2005, I had hit "Not Now" to a reboot request and it had said installation failed. When I installed SP1 on my desktop and said "Yes" to the reboot request, the problem went away, so I guess it was fixed in SP1 but the installer is a bit picky.

Wish I had that advice before as I wasted a day messing around with an MSDN CD, trying to work out what to install and what not. So does the eVC 4 download include an IDE? If not, what do you use?

No GDI Experience. I take it this would be the library of choice for drawing the screen of a today screen app? Stuff like the HTC Home clock or the new Face Contacts - they would likely use Native C++ and GDI? Doesnt strike me as something you would do with a form.
Also, anyone got the skinny on vertically scrolling by click-and-drag inside a today screen app? Just a case of enabling a parameter? Has to be coded manually? Best way to do it smoothly? If you have seen the Conduits Pocket Player 3.x browse list - how it "eases in" and "eases out" at the ends of the list, has inertia so you can "flick" down the list, the alphabetical bar instead of the regular scroll bar - is that all coded manually or is there an api or something that can help?
Thanks for the help!
I just noticed your apps in your sig - checked out LVM time - noticed there was source - wooohoo! I generally pick these things up by example.
All that code just for a (configurable) clock on one line - wow. Great though, a really good example of a today app - minimal enough in functions so it is easier to suss how it all slots together, but full featured enough (implimented example of an options screen - yay!) to show how to do various things.
And Gnu as well! Nice, this will be the basis of my first test project too I think - at least now I have a framework to test out what I want to do and how to go about it without having to work out how to code the basis of the application.
I thank you from the bottom of my heart sir.
I tried to build it in VS2005, but I got a
fatal error C1083: Cannot open include file: 'todaycmn.h': No such file or directory
A quick google search showed todaycmn.h was part of the SDK, I found the file, dropped it into the headers section of the project, but no joy. I will probs just try eVC.
Oh, and having developed a today plugin, maybe you can answer this one:
As far as I can tell so far, debugging isn't very easy with a today app - something to do with the fact that the dll is not releasable? Is this an issue I will come up against? I hope its not a case of "reinstalling" the app each time you want to test... I was thinking maybe along the lines of have it as a normal app for debugging, then make it a today plugin when you want to build to use it?
I dunno, probably trying to run before I can walk, my books shoulda been here today, oh well. Sorry for all the questions...
@evilc:
Are you using standard Win32 or MFC?
You may want to try using MFC since you get the flexibility of native development but with some nice class libraries that make your life easier.
As for click and drag behavior, that is usually implemented by handling the WM_LBUTTONDOWN, WM_LBUTTONUP and WM_MOUSEMOVE.
When you get wm_lbuttondown you set a flag that says the user is dragging. You use wm_mousemove to update the stylus position as long as this flag is set, then you unset it on wm_lbuttonup.
That's the basic idea anyway. Someone made a post about gesture recognition in this forum a few weeks ago with sample code. You should see if you can find that.
Managed Today Screen plugins
See:
http://msdn2.microsoft.com/en-us/library/ms839442.aspx
for some background on the concept.
And:
http://www.christec.co.nz/blog/archives/279
Outlines what I think is a very ingenius technique for managed today screen plugins.
For those of you that want an easy way to make a today screen app in c#. Chris did all the C++ work for you.
Also I forgot to mention that the SDK samples cover all most every application type you can think of. Most of the good ones are Win32 though.
Also, keep in mind that you can use P/Invoke from your C# apps to call native APIs. So don't let people tell you you need to use C++ just because you can access more api's. I will say that you should use C++ for games, or other apps that require high speed or advanced GUI's (it is VERY hard to do interesting gui techniques with C# and interop, trust me).
And finally, I would highly recommend using the most recent version of visual studio you can get (especially if you're using vista), unless your machine can't handle a newer version. I say so because visual studio gets more and more powerful as an editor with each new iteration and I personally can't go back after I get used to the new features they introduce. And the new versions are almost necessary if you're going to do .net development.

Hey guys,
I want to know what cool program, functionality, or software you would like to see created. I am a .net programmer (among others) and would like some ideas of projects you would like to see. I would like to stay away from a graphic intense program and involved games, so think functionality, usefulness, fun, etc. If I get some good ideas, I will then add a poll, vote on the best one, then build it. I will release it under my donationware license which means it will be free. Right now I am finishing up my Golf Gps program (and will continue to support), but will start this project once we get it deceided. So Shoot me your ideas!
Gudy

Hi,
Maybe simple for .NET, but for me impossible to do (without performance/battery penaulty) with basic4ppc or mortscript. And thats all I can handle.
What I would like to have is a program that enables me to execute programs when specific events occur. I'd like to know when AC power gets connected/disconnected, when there is a change in screen orientation, and when a headset gets connected/disconnected and so on. Maybe even when an internet connection through WIFI is available/unavailable.
Also I'd like to know is a specific BT device is connectable/conneted. I'd like to know if a specific WIFI network is connectable/connected. I'd like to know if I'm at a specific location. All event driven, without a performance consuming programing loop or battery drain.
Yeah, all or even some of those options would make my digital mobile life so much easier
Good luck huntig for input, if you ever get bored contact me and make me happy
Cheers,

Doable, handy, not a massive undertaking, I like it! Not sure I would go the .net route on something like this, as really a GUI is not required (except for settings maybe) and the overhead is large with .net. Certainly will add it to the list. Keep them coming!!

This would be pretty difficult unless all of developers used the same programming langauge/technique. The only real feasable way I see this working would be developers using a common set of graphics. That would be more of a graphic undertaking instead of programming. I do like the idea, but pretty hard to impliment.
Thanks

I would love to see something like Launchy for launching apps and files etc. as well as quick search of various types online. I'm guessing the on the fly search would require too much processing power, but if it's doable it would be awesome.
http://www.launchy.net/
I'm interested in new ideas too. I also use B4PPC.
Here's a few ideas:
-A tamagotchi, really. I was about to try this out tonight but Paint hates me.
-An app launcher like PetitLaunch on PalmOS. It's something that can pop from any app (hardware button) and when you type in extra letters it filters which apps are shown. I got this started and I can give you the files if you want.
-Pursue the development for Tippy. The source is on Nicbou.com/downloads if you want it.
-A time clock. A friend of mine notes down how long he works to make sure he doesn't get screwed and it takes him several minutes every week. He doesn't have a Pocket PC but maybe someone would be interested in something that tracks the hours you work and calculate the salary. I almost did this too.
And don't forget to share the source! If you need any help with B4PPC I'm here

Sounds simular to the app launcher listed in the next post, seems like there is a theme going on here, you all need some sort of good app launcher.

I'd like the Launchy features for search-on-the-fly off on board apps and file launching, but ever more for different site searches (google, maps, wikipedia, live, youtube, Amazon, etc).

I had to look up tamagotchi, either I am too old, or just out of the loop to know that 10 million of these things were sold! Wow! That could be fun, but would take a pretty fancy AI type system to really be fun.
A form of Tippy is already out there, 1-calc has some of the features built in already.
A time clock could be cool, maybe a stop watch type thing perhaps?
Never used B4PPC, I mainly use C# and Visual Studio. It looks like the old Visual Basic for desktops. And last but not least, depending on the project, I more than likely will release the source.
Thanks!!! Keep'em comin!

File Explorer Needs Help
Has anyone wanted to see a preview image in explorer's folder??
I'm not talking about fexplorerext2. although it is a fantastic enhancement; it takes a long time to load the preview immages.
I have a better idea (well, actualy MS thought of it first)
THUMBS.DB
for every folder that has an image file, this dll is created to replace cache of images. this way ou do not have to load it everytime and scale them down for thumbnail view. it is already there specificaly for each folder.
This alows the explorer to show a preview of the first image in the folder (or last created/accessed)
This is whatt I think WinMo is lacking - windows. lol.
I do not care much for the tabbed browsing. it hurts my head. too much scroling and not enough info. Icons work better I think, and waste less space on an already small screen.
well, that's been on my wishlist for a very long time. a dll that ataches to the already existing explorer making it work better.
Thanks for workin g on something new
program that makes led lights flash when phone rings would be nice
Interesting...I will have to think about how to tackle that. It would basically take a new file explorer (like total commander). This might be a bit larger than I want to tackle, but will research it a bit before ruling it out.

Fexplorer2 is basically a dll that works with the original file explorer context menu. there is a small exe that overwrites the original explorer to make it think that the explorer"s context menu has already been opened.
in a way it maybe possible to write a new dll and two exe
EXE 1 to replace the file explorer
EXE 2 to make thumbs db
DLL (conte4xt menu that alows to view as thumbnails/list etc ; as well as launching the second exe to make a thumbsdb)
maybe you can get some help from Hou Ming, the guy that made that program before.
it would be cool if you could get some of the old emus like pocket gba and pocket snes with window 6.1 I know i would be happy.

I have been looking for a program that would stop the music (S2P, Audio Manager, or WMP etc...) if during playback of the music the headset is removed. Or for instance, when the device is on vibrate and you connect headset, it automatically changes profile to normal or something.
Another one is when I dock my device (or connect AC basically), I'd like clock program (or home screen, or photo slideshow, etc...) to come up automatically.
A feature that I miss from my older phones is the ability to set them to beep every minute during a phone call.
Now these are very general and not specific features. If you have any questions, don't hesitate to contact me!

The launcher on the 103 looks a lot like manilla, I know it is diff, but to me it seems mainly by presentation, not functionality. I do however like the notification top bar like that on android. Not sure how difficult taking over the top bar would be. I will do some digging.

I am currently writing an application for my WM6.1 device (HTC TouchHD), and wondered if anyone had come across a site, or if someone could point me in the right direction for finding a nice way of writing 'finger friendly' applications. By finger friendly, i mean being able to scroll with my fingers and so on. Or if there are any open source applications that I can use as a reference?
I don't particularly want to say what application I'm writing just in case it falls to pieces, but rest assured once it's written it will be put up on here!
Thanks,
evorgevol
I have just found this page which does me for scrolling parts of my application. The main thing I'm having issues with is that I want the main menu interface to resemble windows 7 media center, see here for a video of what effect I'm trying to achieve.
I know it's quite complicated, and I'm not the best programmer in the world, but hopefully I should be able to do it??
Any help will be appreciated. Thanks,
evorgevol
If I understand, you're trying to create an UI with a scrolling list useable with fingers.
Each item in the list, once selected, let appears different choices about this item (IE : a "Appointment" item in the list, when you select it, you have the next appointment displayed....). It that right ?
Doesn't it look like the new WM6.5 today plugin ? If that's you're idea, I'm 100% on your side to develop a today plugin looking like these menus (WM6.5 / WM7 MC) !
(In fact, I'm already searching if somebody could develop something like this : http://forum.xda-developers.com/showthread.php?p=3375478)
The one I'm doing is not necessarily for a today page, more for my own application, tho it should be able to be easily used in any other application once the code has been written. I just need a push in the right direction for me to be able to write the code in the first place. I'm also deliberating what format to write my application in, and which ones are available. I will only be supporting from WM6 onwards, tho it could potentially be backwards compatible with 5. Ideal would be silverlight being able to be used, but unfortunately that hasnt been released for mobile yet (it would mean that my application should run on any platform that supports Silverlight).
Try iContact. I suppose the code is open. Also try PockeTwit from google code. Install these apps and if that is the effect you want to achieve, I suggest you grab the code and understand it (that's what I would do if I was in your position)
