Favourite application framework - Win32, ATL, MFC or .NET? - Windows Mobile Development and Hacking General

Hello developers,
What is your favorite application and GUI framework for Windows Mobile development? I have played a little with different options, and I'd like to get your opinion on it as well.
As far as I can tell, here are the options:
Win32:
+: Small executable files, small memory footprint, very fast startup
-: Archaic and terrible API. Not object-oriented. A pain to work with
ATL:
+: Same as Win32: small files, small footprint and very fast startup. Object-oriented-ish Win32 wrapper
-: Not too well documented. Seems to be more targeted towards making redistributable GUI components. Almost as painful as Win32
MFC:
+: Extensive object-oriented API. Provides a better UI framework than Win32.
-: Big and bloated. Executables get bigger than with Win32 and ATL. Although it's designed to be oo, it's still archaic and rather painful.
.NET:
+: Modern, well-design and well-documented API. Lowest development time. The assemblies can be ran and unit-tested on the PC during development.
-: Depends on the .NET runtime to be loaded, and startup time is therefore at minimum 2 seconds. No or poor access to hardware-near features like DirectDraw.

Do not forget Wrapper Libraries around win32.
Like PPL: www.arianesoft.ca.
Nor java, for that matter
In any case, it really depends on what you want to do. I've actually used a combination of all three "main" environments (that is, ATL is taken out of the equation... It's really an old one which should NOT be used for new development).
Oh, and native functions can be called from .NET too, just like you'd do a pinvoke on any win9x dll.

Thanks, I didn't know about PPL. I'll have a closer look on that one.
I know that native functions can be called using PInvoke. I've been using that for simple things like playing sounds. However, as far as I have understood, it's not possible to use for example DirectDraw in your own custom GUI components.
Have you actually used Win32 AND .NET in the same project? I thought interop was impossible on mobile devices?

Well, i'm not so sure it's "impossible". I actually agree it would be pointless (too slow to be of any use): just find a good pocket PC native engine (I don't have any link atm).

While the API itself isn't OO, but your app using it can be such
ATL & MFC: I wouldn't touch them even with a looong stick
.NET:
You're right, it gives you a nice API, but at the costs.
Generally, you should choose your way with every app you're starting with - the choice should be dependent on what your project is for.

I have to disagree with jahnotto on the original assessment:
Win32: First there is nothing "archaic" about it. These are pure APIs that give you full access to your system so as long as you are using Win32 OS you have to go through them one way or the other. It is C++ language that provides object orientation support and there is noting stopping you from creating your own classes that take full use of the API.
(Yes this is my favorite method of developing because it is gives you the fastest and cleanest binaries)
ATL: I heard good things about it, but did not get the chance to use it. However, it is just pre-written code. You are still writing using Win32 but some nice people went and coded some classes in advance for you.
Thats the one and only difference between it and "pure Win32".
MFC: Its very similar to ATL - just a bunch of classes that wrap APIs but its much balkier and poorly documented. It is useful if you need to make some quick tool with little code and a single dialog but not something you want to use for a serious program.
.NET: Here is my biggest disagreement with the thread starter - simply because he sees a positive side to it
Yes, .NET saves time for development but:
- Running .NET app on PC without emulator though possible will not give you proper indication of how this app will function on a PPC so its pointless.
- Because it need the .NET CF it takes a lot more memory then it should when running.
-The poor access is not only to "hardware near" features. You can't even make simple things like today plugins, keyboards or control panel applets without using native code components.
- I have yet to see a "well documented" MS product.
In short my general opinion on the .NET is that the devices are just not powerful enough yet to allow such wasteful programs plus they severely limit the developer on what parts of the device / OS he can utilize control.

ATL or MFC

Hey,
I'm trying to make a User Interface for a program using Visual C++ 2005.
I have two options for Smart device applications.
1. A project for Windows Mobile and other Windows CE-based devices that uses the Active Template Library.
2. An application for Windows Mobile and other Windows CE-based devices that uses the Microsoft Foundation Class Library.
Which is the right one to use for Pocket PCs?
No idea 27 - I've never used either ATL or MFC. I do all my stuff in pure Win32. It's not necessarily the best way, but it's worked fine for me so far, but I do very limited GUI stuff.
BTW - regarding your signature:

Hi 27,
I'm not sure what you want your GUI to contain but a simple Embedded MFC app with a dialog might be a good way to get going?
best of luck...

I've been developing for big Windows since '92 and have done one or two small CE projects. Straight API programming is a bit tedious but it's pretty straightforward and will help you learn the fundamentals. It also produces the tightest code, an important consideration if you're looking to run on smartphones.
Avoid MFC like the plague -- MFC apps tend toward the large side, and it tends to force you into a document/view model that might not be appropriate for your app. I did quite a bit of MFC work in the early and mid 90s; most of my time went to working around MFC's limitations.
If you go the ATL route check out WTL, a set of C++ template classes that extends the UI functionality of ATL considerably. I've been using it since it first came out and wouldn't switch back to MFC if you put a gun to my head.
I agree. MFC makes everything less straight forward. Why use something designed to hide how it works? I use plain win32. After the pain of starting from scratch you eventually build up your own code base to reuse.
both can be used
MFC is old and bulky but many things are don automaticly
compared to win32 sdk
you can also use .net but they are somewhat slow
but dont use much space
win32 sdk is the fastest and can do anything but it's the most work

How can i do this on VisualStudio 2005?
I'm a bit new to this.
Strange question - you develop in Win32 by NOT developing in MFC or ATL
The other frameworks are built on top of the native Win32 API. So learning the bareknuckle stuff first helps you to learn how to get the most out of the other stuff.
V
27 ask a importent question imho
can ppl make nativ CE api projects in 2005
or do you need embedded c++ to do that?
btw i believe that embedded c++ is free so if 2005 cant do it
ppl can just get the embedded version
VS2005 does native Win32 (2003, Smartphone and WM5).
EVC is of course free, and runs much better IMHO (eg no bugs in the Remote Tools etc, faster). I can't think of a good reason to upgrade unless you're developing expressly for WM5 or using non C++ languages, for which VS2005 is required.

Which Development tools for WM 6

Hi all you experienced WM programmers.
I'm new to windows mobile, but program other environments for a living(micro controllers, embedded linux, win32 etc)
I was wondering what the development tool of choice is for WM ?
I know that on Win32 .net development sucks blocks...yes I develop extreme low latency process control stuff and the abstraction from hardware in .net makes it unusable for such programming as you totally lose control over memory allocation etc.
Being as the WM is such a limited devices I presume the same issues are found there as well. So what are you guys using to develop? strictly embedded c/c++ or is there something else out there that is useful?
Thanks in advance for any suggestions
You defiantly want embedded!
You can use the free eVC or the expansive VS 2005, but if you want quick native code programs or to write system components like today plugins and keyboards this is the only way to go.
If you think .NET is bad on a PC just wait till you see it in WM. Because of the limited resources of these devices its a sluggish nightmare!

Other Developer environments.
Have you considered the PPL programing environment.
Provided is an IDE environment both for the PC and PPC. This means that applications can be developed and run on both platforms. Not sure about latency, however you can create .exe files from you're code and interface to external DDL's.
There web site is http://www.arianesoft.ca/page.php?1 and a trail version can be downloaded. The trail gives basic functionality with a 15 day full function registration option.
The Developer is quite open to questions and the forums are also quite active.
Not sure how deep you wish to access the OS/HW however it may be worth considering.
Cheers.

Yea, that one slipped by me even with the spell checker.
Excuses:
1) I was tired.
2) English is not my native language.
I'll just leave it there because its pretty funny. And hey, using native code instead of .NET is in defiance of Bill's wishes!

Getting into WM5/WM6 programming?

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. My biggest project so far though was an open source google maps mod to put on your website - thousands of lines of php / js code, mysql backend and AJAX tieing it together, some graphics routines etc, so I am no drooling n00b when it comes to coding.
How easy is it to develop basic stuff in WM?
I have access to MSDN, so I can get Visual Studio (2005 for sure, maybe later versions), so I think I have access to the apps I would need. I just ordered some books to help me along, but was wondering if I would likely face a steep learning curve.
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.

Comments / suggestions?
I would also be very interested in a thread or good reference on how to start to program app for mobile gadgets. Actually i'm a Delphi coder, and i would like to implement some applications on WM platform, but when i search over internet there's plenty of information, but no usefull information with "real-life" recomendations.
depend on the platform and language one wish to use really
there is c#.net, vb.net c++.net
c++ miniMFC, c++ PureWin32 sdk
oldVB

about delphi i dont know if anybody got some info i would say borlands site
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
levenum said:
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.

is really useful, maybe if it were expanded upon, info such as for this route you need visual studio, etc, etc it would make a really good sticky for the dev section.

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.

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.

Programming CE, Book and resource recommendations

Hello,
After a decade of not doing C, I find that alot of things have changed when programming c++ native for CE. Even things like:
string somestring;
no longer function. Wow!.
strcpy has been replaced with StringCchCopy. Wow, MS has done a number here... and so on...
Anyhow I searched xda and found allot of good threads. But what if I'm looking at re-learning C++, with a focus on CE programming only? What books and other resources would you recommend, its almost like starting from scratch. I got vs2005 + emu + been reading allot of MSDN, did some basic apps. etc.
BTW: How the .... do you declare a variable length string???
and in VS2005 is running the debugger the only way to get the app to start automatically ???
Thanks
*bump*, anyone?
Couple of notes:
1) I strongly recommend avoiding VS, it is unbearably slow and balky.
2) strcpy and all the other functions are still supported by c runtime on CE (VS 2005 complains about them but you can ignore it). The problem is all windows API on CE use UNICODE so you have to declare strings as WCHAR (thats MS speak for unsigned short) and use wcscpy, and such.
3) The only book I know on CE specifically is this and I only read the two sample chapters online, so can't really recommend it. (Though the sample chapters were very useful). What you need is to get a good book on Win32 programming that will get you well on your way.
4) There is an MFC class CString which wraps up all string related functions very nicely. If you are not using MFC but clean C/C++ the only thing I can think of is malloc and free or the C++ versions new and delete.
Check out the links in my sig if you want to see code examples of small but functioning apps.
I disagree with levenum's comment on VS, but agree at the same time (weird I know). I wouldn't use VS for native development because it has A LOT of extra features that I think would be useless for native developers. Also, the lighter eVC++ has pretty much everything you need to write native apps.
I had this book called "Programming Windows CE 3.0" or something along those lines a few years ago. I got it for like $3 on Amazon. If you can find an updated version of that (or even the old version would be useful) then you should buy it. It will show you all you need to know to get started. You can learn the new api's from browsing msdn.
If you're only a little rusty with C/C++ I would suggest jumping right in to the Sdk samples and seeing how they do things.
Thanks, the reason why I wanted to use VS is so that maybe later I wouldn't mind going into MFC. So having one platform would be nice.
So far I have done some basic things, like drawing, etc, but I find I'm having a harder time making strings and including the api's to work. Almost all of the msdn examples fail to compile properly.
I have an old book MFC for Windows 95 by MS, is it even worth looking at ?

could you provide some links for msdn. also i know how to program in c but how do i compile a program for windows ce could you recommend a free one. thanks
The only way to code for Windows Mobile for free is to use embedded Visual C++. You'll have to google it to find a link.
Once you have that downloaded, check out:
http://msdn2.microsoft.com/en-us/library/bb158662.aspx
The new solution files most probably won't open in eVC++ but you can create new projects and add the source files yourself.
You'll want to look at the samples in the Win32 folder.

That's not entirely true - there's still ceGCC (it works on linux or windows using cygwin) - however this one lacks resource (window, forms, etc) editor (but if you have resources already created it will compile/link properly). But it works great with apps where you want to handle all the graphics and user interaction by yourself (like games, or programs with 100% custom UI), for example using SDL, pocketHAL, etc.
Also, wxWidgets seems to have support for windowsCE, and might be made to work with ceGCC, but i haven't tested it yet.
Sorry, I actually meant to put "(I think)" after that sentence lol.
Actually I think you should be able to use any C++ compiler as long as you have the necessary libraries, and I think all the libs you need are in the sdk download. But the easiest route for beginners in native coding is probably eVC++
Well, now i can agree with you
That is, unless you want to create games - in that case ceGCC+XFlib might be a good way to go for someone with general programming knowledge, but not familiar with winCE-specific coding. Some games coded with it (and their sources) can be found on XFlib homepage: www.xflib.net.
thanks for the info
Ok, as I wouldn't mind at a later time going into MFC, and building dll's for mobile. How much "harder" would it be for me to learn VS2005 native for ce instead of using evc++ ?
Just trying to weight the cons and the pros. BTW where can I get eVC ?
Thank you.
Two more free options: PellesC and Lazarus + WinCE add-on
I don't think it would much harder. Once you get the hang of it you'll find that it makes life much easier. If you buy a boxed retail version it comes with a nice book that will take you from n00b to master in a few hours (not really but it's still a great reference).
I think the hardest part of upgrading to newer versions of VS is learning the new project file setup. Atleast that's what it looks like from watching other students at my school go from VS6.0 to VS2k5 and 2k8.
Also, I should note that I prefer VS2008 hands-down, but I don't disagree with other people who say eVC++ is faster. While I haven't done any real native development since eVC++ 4 was new, I still dabble a bit (especially since getting active on this forum) and VS2005 works great to me.
So, my advice would be to use the newest tools available to you, unless money is an issue. But don't be worried about upgrading. Your life will only get easier once you do.

Well I just got eVC and will give it a try too. But I am pretty much used to vs2005. I do not think I can't afford the vs2008 right now. How much difference is there between 2005 and 2008 when it comes to programming for WM?
I'm looking to create some commercial applications for WM. For the last 10 years I'v been doing .com apps, now I figured I would do some for the mobile platform. We have all the graphics/design/marketing guys for .com, so it should work out just fine for WM.
One thing we noticed when working with exec type people is their frustration, I see exactly how we can help them resolve their frustration with WM, Symb, and java type phones...
Thanks

Honestly I wouldn't rush to upgrade. VS2008 is better, but doesn't add much to the WM development arena.
And if you already have VS2005 and are used to it, I would stick with that and forget about eVC++. You should give the compact framework a try. I promise you'll love it
compact framework, that's a part of the .NET isn't it?.
For the time being, for learning purposes, I think I will stick with the native for now. Once I get a grip, I will explore .net. The thing is I really don't like bulky apps for WM. Most of the apps I came across that required the .net framework were slow, any apps that use the .net with a today plug in seem to really slow down my phone.
BTW is HTC Home plug in written with the .net?
Thanks
marek, it seems to me that you are under the impression that you need VS 2005 to use MFC.
eVC fully supports MFC as well as creating DLLs and MFC DLLs.
It admit the reason I don't like VS is because I only write in native and don't like .NET languages a lot.
Since you want to create commercial apps you should note that any app created with WM 5 SKD will not be backwards compatible with WM 2003 which reduces your clients range.
You should compile with WM 2003 SDK which is forward compatible.
Our primary target audience would be WM6. We will make every effort to make WM5 compatible apps. Yes it does reduces significantly the client base, but also there are many positives...
We are still looking for more programmers for the simple concepts we have developed. I believe this will work out just fine. Having WM5 support is a "would be nice" but not required. WM5 has a bag of problems, 2003 I don't even want to touch it.
Thanks
I have to admit that I love VS because I love using .net
But VS is also a much more powerful editor in general than eVC is. It's still nice but the experience isn't as smooth as it is in newer versions, which is expected since the newer versions build on the previous ones.

Fastest/Lightest way to code WinMo?

Hi,
I'm the author of a fairly popular j2me chat application, and I've been pondering making a native WinMo version for a while now. I've thought about a .net port, as it would probably be easiest, but all the .net programs I've used seem dead slow. Or am I totally off base with that?
Is there another environment I should look at as an alternative? Keep in mind, I don't have visual studio.

You can still stick with j2me, you'll just have to change a few things to make the program compatible with the java midlet managers for WinMo. You should read up on the Mildet Bible: http://forum.xda-developers.com/showthread.php?t=339579
Hope this helps
From testing open source apps and they ones I have made I found that C++ is faster and c# is easier but a little slower. I used c++ for along time but have moved on to C# and love it.
u can just develop in any .net language, then use tool like SmartAssembly to optimize and convert the code to binary.

Hello, I strongly recomend to use c++ for winmo dev.
cheers,
Hlov
The fastest and leanest method is C++, available in Visual Studio Professional, or as a standalone free download as Embedded C++ version 4. The development models are MFC, (Microsoft Foundation Classes), ATL (Active Template Library), or good old fashioned WIN32.
Of these WIN32 is the leanest, all the others, including .NET are wrappers around it. If you haven't used or seen WIN32 before, expect a pretty steep learning curve. Look at the Hello World example it generates, to try and figure out what the hell is going on. Basically you respond to WM_XXXXXX messages fired at your application by the operating system. Limit the main menu to two items, and WinMo 5/6 will display it correctly, with the main menu options either side of the keyboard/SIP icon, and accessible by the left and right menu buttons. Otherwise it will switch to a WM 2002/3 menubar, which you then have to click on to use.
If you want to go any lower down than this, you will need to brush up your ARM assembly language.
Unless you are developing graphics intensive applications, using c# is fine for applications. C++ is necessary if you are writing games and the like but the SLIGHT performance decrease is not that big of a deal otherwise.

I'm using J2ME polish, so I can (and have) built a build specifically for WinMo, but I want a native version so I can multitask (can't do that with Esmertec) and I'd also like to develop a homescreen plugin.
My app is here:

If anyone has any suggestions on what I should do with a port, I'd love to hear them.

It's been a long time since I've done standard Win32 development, and I really don't plan on going back down that road again. For starters, I imagine Visual Studio would be a dog in a VM (I only run windows in a VM these days, won't run it on actual hardware if I can avoid it).
It's looking like I"m going to try C++ or C# for this. I'd like to do C# because that's pretty close to Java, but I also have moral qualms about using a language designed to usurp a good and popular language just because MSFT didn't develop it.
Decisions, Decisions....
You can also try using Ruby with the Rhodes framework: http://www.rhomobile.com/home
Or you can try using Mysaifu which may allow multitasking (haven't tried any of my programs on it yet): http://www2s.biglobe.ne.jp/~dat/java/project/jvm/index_en.html
