Hi,
Has anyone had any luck with writing Midlets for the XDA2? I'm trying to write one use the camera as a webcam (Yes, I know, a bit ambitious for my secomd midlet!)
I'm using this line:
Code:
Player vPlayer = Manager.createPlayer("capture://video");
I get a MediaException, meaning '...a Player cannot be created for the given locator.' (quoted from MMAPI JavaDoc).
Also, calling the Manager.getSupportedProtocols() method for 'mpeg/video' returns an empty list, as does calling Manager.getSupportedContentTypes() for 'capture://video'.
Has anyone else managed to access the XDA2 camera from a Midlet? If so, what is the trick?!!
cheers
Paul
I don't think anybody's managed to get access to it from native eVC++ let alone midlets, and IA style aren't revealing anything about how their app does it, so I wouldn't hold your breath for a solution... Bloody closed APIs.
Knackers!! :evil:
Cheers anyway! I'll keep poking and see what happens....
Paul
i suspect that their applications take pretty much control direct without using the winCE api
because when i start the cam my clock which it still display stop being 24h and turn to the AM/PM confusement
Intro:
Hi, my name is bart and im a dj / producer
When im traveling i get alot of inspiration. So i would love to be able to make music on my pocket pc. I searched for software like drumsequencer/samplers for pocket pc. ?I found some very basic/not interesting freeware progs. And 1 over the top not realy functional wav sampler wich costs money btw. btw excuse me for my grammar as i am dutch i will likely make some major grammar faults.
So i decided i need to make one my own. and make it good and then release it to the public for free.
The Concept:
Maybe some of you know this program some dont (look it up on google then) but do you remember the program called Rebirth? it is a piece of software by "propellorhead" wich is actualy a digital clone of a oldskool 808 and 909 drumcomputer and 2 303 synths. It also includes 4 basic effects: Delay, Distortion, enveloped cutoff/resonance and a compressor.
Wich are basicaly mathematical formulas wich change the sound produced by one of these drumpcomputers/synths. One of those effects cqan be used for one sound source only.
ok so i basically want to get about thew same specs as that program. Only with less cpu intense graphics, just 1 drum and 1 synth and compatibilaty with atleast the mda vario aka qtek 9100 but i prefer compatibilaty with almost all pocketpc's.
here is a basic list:
1 drumsequencer (with maybe 4 samplekits?)
1 synth (soundgenerator using 4 different wave shapes)
1 cuttof/resonance filter
1 distortion filter
1 delay
1 internal mixer ( each channel will have a own volume knob i guess)
Read this before continueing
Ok so now is the question if you are interested in all this. If you want a program like this read on. If you are good in programming even better.
If you know a lot about music or music in combination with pc software you can definately help me out.
I know almost nothing about programming. Ok i know some oldskool basic, i can do some html and php, but thats it. Tho im not stupid and i learn quick. I also think that this project may be a good excuse to start learning to program. So basically i first need to determine some important facts before i start this project:
Wich programming language is required for this project
How much programming skill will this project need (basic, medium, expert)
What about the soundchips in ppc's and how to communicate with them
Use sound sampling based techniques or sound generating techniques
Are there people to support me, can they help write code, can they help answer questions
And the list go's on... if you think you can answer one of these questions dont hesitade and start to support this project
ok nuf said... lets get back to bussines:
Main functions
Ok so i guess i need some main functions wich would be the core of the program. There needs to be a timecode aka bpm (beats per minute)
This means a play button and a stop button. There needs to be a visiualisation of the drumcomp, synth and effects. I would also like to note that im not planning to use the function of a pattern playlist yet ( a playlist tells the sequencer to play different patterns from a database of patterns).
To keep things simple i want to keep this version just playing this 16 step pattern as a loop. Very important is that all sequencers (synth, drums, delay effect) go as fast as the timecode aka bpm.
The Drumcomputer aka Sequencer:
The idea is to make a 16 step sequencer. For those who dont know what that means plz look it up on google. i would like to implement the feature to use different samplekits from a list. i als am wondering wich format whould be best to use to compress these samples... wav, aif, 8 bit 16 bit 22khz ???!!??
The synth aka soundgenerator:
I want the following functions on this soundgenerator.
It is triggered by a sequencer
You can change pitch of each note
sound can be modified by cuttof resonance
you can choose 4 waveshapes: sinus, square, triangle, noize.
very similar to the 303 in rebirth do it doesnt have to have the same sound just the functions.
The effects:
Need to find the mathematical formulas for these effects and check how to convert them to this program.
Internal:
Ok first i want to tell what ISNT needed. I dont need save to be implemented yet as a wont be using playlist and mulitple patterns anyway.
All sound sources (drums, synth effects) have a own volume knob wich indicates the volume. I want to make a internal mixer wich mixes the drum, synth and effects together according to the volume set by these volume knobs.
ok im done typing for some time... i will do some adjustements to this post later on: and if it gets some serious i will make a good decent, main thread, with the name of the project in the title etc.
Thnx for reading all this and i hope to get some nice feedback... or questions.
greetz bart.
Hello Bart!
First of all, I'd like to say that you are off to a good start by making a detailed project outline.
Although I never done any programing involving audio manipulation I believe I can answer some of the questions you posted here:
1. There are 3 main stream languages to program pocket PCs:
.NET Visual Basic and C#, and native C++ (eVC++)
Unless you can fined .NET objects dedicated to functions you described it will probably be better to use C++ as it will make access to windows API easier.
Also for VB and C# you will need to by Visual Studio 2005, but eVC 4 can be downloaded for free from Microsoft.
2. I estimate this project will take medium to expert programming skill depending on how cooperative windows CE will be with your goals. Hopefully you wont have to access the audio chip directly. Alternatively there may be a .NET component that will make your life very easy try Google.
If you know the mathematics behind the effects you got half the job done and I am sure you will find people to help you with the coding.
So good luck, and remember - people like free software so this project can't be a bad idea!
Ok, with your answers in the back of my mind i did some googling
and i noticed that there is quite some sourcecodes and info for audio programming in c++
check this link for example: http://www.harmony-central.com/Computer/Programming/
Tho in my search i stumbled on another thing... what about java? maybe it wil be a lot easyer in java? and maybe also more compatible? i dunno just guessing here...
anywayz as for the c++ side: i noticed i can download many synths, effects examples/sourcecodes and they are all copyright free. it will be a task of exploring this sources and binding it all together or something similar. is there anyone out there with the c++ guru powers it requires that can guide me in this jungle of data?
edit: o btw does wm5 support DSP ? guess not but worth asking
Hello folks,
a friend of my had a funny idea, putting a shaving sound on his phone and playing it. His phone is the MDA Mini and it really looks cool.
Now don't you think it would be fun to write a little programm which plays such a sound and shows the picture of a shaver on the screen. so that it could be assigned to a hardware button.
http://www.sounddogs.com/previews/36/mp3/292083_SOUNDDOGS_SH.mp3
Could be a nice laugh.
Unfortunatelly I don't know anything about programming....
Or is this just to complicated to write and therefore waste of time.
Cheers
Alex
Wouldn't it be more accurate to make it vibrate, perhaps show the Philishave interface on the screen, and make you more attractive to women/men/animals/vegetables?

haha...that's gonna be real funny. I'm definitely installing it if anyone manage to write it.
Well I think the vibrate does not quite give it the shaver effect. Since it sounds not like a shaver. Listen to the sound:

I already have it on my Hermes using Mediaplayer.
Anybody for programming yet?

I thought this simple project would be a great exercise to use for learning c++, so I bought a book, DLd eVC++ and all the other M$ crap they say you need only to have it crash when trying to create a new project..
So, then I DLd CEGCC to see if it would work, and I managed to compile the "Hello world" program, but when I tried a simple program to load a bitmap and ran into all these missing dependencies (or whatever the errors were).
Well, I didn't manage to get started in c++ because of the lack of information on the differences between the win32 api and wince api, Frankly, I'm freaking lost. In alot of forums I checked out people would ask questions only to be answered with stuff like "Why do you want to do that?"
I'll probably come back to the C++ after it simmers in my mind for awhile.
but, I don't like to give up, and don't mind compromising, so I threw together this package that uses PIE and some simple web pages to do the Pocket Shaver thing.
At least I tried LOL. It's kinda crude, but what the heck, it's for fun anyway.
Joeman
BTW: if anyone knows how to write a C++ program that loads a bitmap and will compile in CEGCC, I'd be very pleased if you'd share the source code...

First, thanks for all the great ideas. I would love to develop all of these if I could, but we have to decide on just one of the programs! So, Since I couldn't add a poll to this thread, I added it to HERE.
CLICK HERE TO VOTE!
I bet I know which will win, but who knows? The poll will end Thursday or Friday (depending on if it is a close race or not).
Thanks

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
cool a programmer who need ideas
I have proposed something here: http://forum.xda-developers.com/showthread.php?t=434925
though it would maybe not appear as a grateful program for a developper ( a toolkit for other programs), it could be a good way to have a large diffusion through many config panels in different programs
it was just an idea

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,
Cacti

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.
Gudy
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.

This would be very difficult as not every device handles the leds the same. Also, not every device has the same leds (color, # of, etc). I think No2Chem has a int. driver, but think it is only for the titan. Would be cool though...

a system-wide launcher dock program like that on the velocity 103 PPC..
here's the URL for the review and video of the app (and the phone)

a new top bar replacemeent/notification system much like the "android Notification Drawer" it can replace the bubble (multiple) notifications icon when you got multiple and simultaneous notifications.. and also make it finger friendly (unlike M2D, no need to go back to homescreen to check email/sms previes and also calendar events, calls, etc.. also unlike big taskbar - from the touch phones, this'll have previews)

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!
Thank you,

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.

Hi mates, i need an advice about programing a simple app for WM6 actually for my Diamond, which should #include a simple main menu with settings, and most important a Homescreen plugin to show some text depending on a time of a day, and maybe some pics(small pics)
so here is the question, what coding programe would you recommend me to use? i know C and Pascal and a bit of C++
The app i want to do is about foreign language learning, and should show some frases or idioms during a day on the home screen,so you can observe the new words when you simple look at the homescreen
Thank you in advance for any kind of advice

I'm not a pro on legacy today plugins, but in order to make a today plugin .dll you'll need to instal visual studio .net (I use 2008, sometimes). Here's an interesting pick on how to get started with today plugins: http://msdn.microsoft.com/en-us/library/ms839442.aspx .
It would be a lot easier to make a plugin for WM 6.5 Titanium, which requires les BS . You could use basic4ppc or mortscript for this purpose, which are a lot like visual basic.
rpereira thanks a lot , i'll give it a study.
hope i can create smth worth the effort
