SetPowerRequirement doesn't work

Hi,
I'm trying to port some OpenGL software to the Leo (HD2) and everything is working OK apart from the screen is dimming.
Looking at the MSDN info I should be able to do
SetPowerRequirement("BKL1:", D0, POWER_FORCE | POWER_NAME, NULL, 0);
but this doesn't work.
Reading the current value using GetDevicePower() returns an error.
Does anyone know how to stop the screen from going dim?

[REF][Manila] Different approach to the BG4All mod

This thread is mainly intended for developers - it's a proof-of-concept to show a new approach to the classic background for all tabs mod.
This is only a proof-of-concept and I won't develop it further because I don't use BG4all myself. But my hope is that the basic concept will be helpful to others, and that it will develop from there.
Traditionally the mod is made by moving the "HomeBackgroud" instance from home.mode9 to manila.mode9. The problem with this is that those are 2 of the most important mode9 files in manila, so they are also needed for a lot of other manila mods.
The result of this is that other mods now have to be made in 2 version: one with bg4all and one without. Also, if a new manila build changes one of the mode9s, the bg4all mod needs to be remade.
A different way of doing it is thought the lua scripts. Specifically only one script needs to be modified to make bg4all: homebackground.luac.
This way no mode9 files are modified so bg4all can be compatible with a lot of other mods. This way mods don't have to be redone to include bg4all.
I've included the lua source of the modified homebackground.luac for manila 2.5 with comments about what’s been changed, but you can also compare it to the original to get a better idea. At the bottom is a ready-made cab with bg4all for manila 2.5.
Here's the lua code:
Code:
-- Decompiled using luadec 3.2
-- File name: 090a4ee8_manila -- \windows\htc\home\scripts\HomeBackground.luac
require("asyncimageloader")
require("shell_svc")
CachedImagePath = "\\Windows\\HomeBackground.img"
HomeBackground.Opacity.value = 0
-- Home Background is not needed at all, so it should be made invisible
-- and we can forget about it from here on
-- from this point on anything that operated on HomeBackground is replaced with BackGroundLevel0
-- compare with the original 090a4ee8_manila to see the differences
-- BackGroundLevel0 is the default manila background that appears on all tabs

I just wanted to say THANKS! for all you work on the community and tell you what a great find you did "it looks so obvious to do it that way now" also THANKS! on your work on the decompiler many mods would not have been made without it.
By the way THANKS! again

nice, thank you

Perfect, once again a fantastic mod from you!
Thanks a million

Thanks a lot cookiemonster. Any plans to do one that also works to assign landscape wallpaper?
edit* Just tried it on landscape manila and doesnt work at all. Just get plain black background in portrait and landscape.

Awesome. So does this method keep the animated weather on sense 2.1? Could you cab that up PLEASE!!!!!

You're referring to manila 2.5.1922.2911, right?
That one also needs the manila.mode9 to work, but that's only because it has a built in bug in it's original manila.mode9. (I've made a cab for it here: http://forum.xda-developers.com/showpost.php?p=5499189&postcount=47)
Now, it might seem a little contradictory, that in the first post I say "no need to modify the mode9s", and now I'm saying 2.5.1922.2911 needs a mode9. But, believe me 2.5.1922.2911 is an exception rather than the rule. That version is bugged, and it's the only reason it needs the mode9 to work.

I haven't tested the animated wallpaper, only the regular. This is only a proof-of-concept and I won't develop it further because I don't use BG4all tabs myself (I prefer making better quality wallpaper with HDWall).
But my hope is that the basic concept will be helpful to others, and that it will develop from there.

Thanks Man,
A great new applicaiton. It also works for me Many Thanks

Thanks much cookiemonster! I'm actually getting used to not using bg4all too. Manila runs much smoother without. Maybe I'll make some high quality walls with hdwalls also. But, it doesnt work on manila 2.5.1922 does it?
edit** Ok, now this was kind of weird. Installed the cab and all was fine, til I switched to landscape and back. My wallpaper disappeared after that, never to return Naw, after soft reset, it came back. But, same thing keeps happening.

If not here, i dont know a better place to get capable people that could MAYBE help me on this matter.
I am Using the "old" Tf3d (not leo) on my X1 and i came across a pretty sad thing.
TF3D scales down the Wallpaper and makes it look worse. I made a mod for a self changing wallpaper for tf3d so i got into the lua files quite a bit half a year ago.
So my questions are:
Do you have any idea where the image is scaled down in the lua code?
can you think of any workaround to get a better image quality?
I think this would make it SO SO SO much better, as the images in full quality look just stunning..and on tf3d they look just blurry.
And another brief question, did the lua decompilers got better?..half a year ago almost any big lua file could not be decompiled properly..and so could not be changed at all.
thank you in advance,
Daranus

HDWall works with 1922, but my patch for that version needs to be applied.
The landscape problem: As I've said, it's just a proof-of-concept and I won't develop it further. Anyone who wishes to do so: In order to fix the landscape problem, the BackGroungLevel0 texture needs to be reapplied in the rotation function.

It's scaled down to 512X512 in the homebackground.lua script.
One workaround is to make it use 480x800 jpegs or pngs, but that still isn't optimal because Manila displays those formats with some kind of dot artifacts.
The best quality solution is to use Manila's native QTC format, but you have to make your wallpapers with HDWall: http://forum.xda-developers.com/showthread.php?t=503511

I've been developing LuaDec recently and made a lot of improvements - it can decompile more than 90% of all Manila script. The link to the tool is in my signature.

hej Co0kie!
does this one work with your 16-20 Quicklinks/Appointments beta_1.5?
the QL app is a sure nomination for some HTC price. I'm getting used to not having a B4all, but would be sooo nice to have this working too

I just checked it and it's working fine with v1.5beta2. (on Manila 2.5.1922.3829)
And I really don't see why it should be causing any problems. The two mods use different files.

Thank you for your answer!
That doesnt sound good..i personally use S2U2 now, as the wallpapers there look just stunning..it's a shame that we cannot get it to work properly within manila...do you know if it is the same issue with version 2.5 cookiemonster?
Wow thats awesome..when i was developing a bit stuff it was just a pain in the ass because almost every big manila file couldnt be edited..
Big props to you mate, great great work, greatly appreciated!!!..maybe i will take a look at it again nuw...as making wallpapers like that sucks..and i think it wouldnt work with my bg changer mod....anyways, thank you man!!!!!!!!!!!!!!!!!!!
Edit: Yup, i will definitely try to figure something out there..is there any "comfortable" way to work with your new luatool thingy?..i only saw 12's kitchen and that is not using a new version and is not that easy configurable to use your new thing there...
atm i search for the asyncimageloader but didnt find a way to properly search for it *laughs*..i have to get into this stuff again for real..

[Q]How to rotate screen?

Hi gents.
Today,I want to ask someone,how can I programm,that my software forces the screen to be rotated into landscape or back on the go(for example after starting). I try to programm something with Embedded Visual C++ SP4. Actually I don't see any problem with this,but I cannot find any source.so I will be very grateful for that.
Anyone can help me with this?
Thanks in advance.

Take a look at
DEVMODE DevMode;
memset (&DevMode, 0, sizeof(DevMode));
DevMode.dmSize = sizeof(DevMode);
DevMode.dmFields = DM_DISPLAYORIENTATION;
ChangeDisplaySettingsEx(NULL, &DevMode, NULL, CDS_TEST, NULL);
DevMode.dmDisplayOrientation = DMDO_270;
// this should force a size message
ChangeDisplaySettingsEx(NULL, &DevMode, NULL, CDS_RESET, NULL);
Jim

Thanks,that works perfectly.

[Q] AudioRecord on Galaxy S

Hi,
I developped a dictaphone on android that records mp3, ogg, wav files ...
It works on HTC, nexus, ... but I have some problems with Galaxy S compatibility.
I saw that some other developper using AudiRecord faced the same problem too and resolved it, but I found nothing on internet on there solution.
As I can't afford to buy a Galaxy, I ask your help here
Here is a piece of my code :
int bufferSize = AudioRecord.getMinBufferSize(f, c, e);
AudioRecord recordInstance = new AudioRecord(MediaRecorder.AudioSource.MIC, f, c, e, bufferSize);
byte[] tempBuffer = new byte[bufferSize];
recordInstance.startRecording();
while (...)
{ buffer = recordInstance.read(tempBuffer, 0, bufferSize);
}
recordInstance.stop();
recordInstance.release();
I tried all these values :
for f : 8000, 11025, 22050, 44100
for c : AudioFormat.CHANNEL_IN_MONO, AudioFormat.CHANNEL_IN_STEREO
for e : AudioFormat.ENCODING_PCM_16BIT
I ve seen, that getMinBufferSize (on Galaxy) always return 640 and that Stereo isn't used.
I don't know where my code fails. Did someone had the same problem ?
Did you reslve it ?
Thanks in advance,
Dje073.

Since audio recorded with the SGS is just a piece of crap, nobody is going to use it anyway
But of course, if you really want your application to work on the SGS I don't think I have to complain.

Is there a way to fix the audio quality? It is really awful.

You may not be wrong, but as Galaxy users ruins my stats rating my apps 1 star on 5, I have to do something
If not recording in 3gp format, the sound may be correct, no ?
I'd like to provide you an app to demonstrate it, but I don't want to buy a SGS for it ^^

I don't think that will make a difference. As a temporary solution you can edit the description of your app and tell the SGS-owners you are working on a solution. If they still keep ruining your stats they're just assholes

Already done, but not very effective for the moment
I'm sure audio quality is not as bad if you record in raw pcm.
Why Samsung did there own implementation of AudioRecord ? :/

I don't think this kind of comments will encourage the programmers working for a specific device voluntarily.

I've use TapeMachine on my SGS and the recording quality is excellent. It does ogg,wav but no longer does mp3 due to a licensing issue. I don't understand where this idea comes from that the SGS audio quality is poor. For info, I'm a musician, I use it for recording guitar/voice demos and I find it astoundly good for a phone.
You may want to check out TapeMachine.

You can find my application on the market making a search on "AudioRecorder"

Well I'm not a developer, but I do have Galaxy S, so if help needed from user side, drop me a pm.

Thank you Soniboy
I tried with some friend, but not very effective without being in debug mode on the device.
More, It seems that this bug does not exist any more on Samsung Galaxy S with Froyo.

PROJECT - wireless Keyboard, send WP7 keys via wifi, like bluetooth keyboard

Hello, Im starting a new project. The concept is simple.
Send ip packages to wp7, and a background task translate it into keyboards inputs. so it will works like a bluetooth keyboard or something.
I already able to simulate keyboard inputs. but it only works with special keys such back, home, search, volume, play, lock... when i send a `A` key,, it doesnt make any effect.
but my goal is to send char keys inputs.. im trying to somehow enable the "hardware keyboard". like when we press PgUp into the simlator and type text into it.
I calling the WM6 method EnableHardwareKeyboard(TRUE). but it has no effect also.
Im also sending my current project. The vs2008 for the native dll (for sending keys) and the vs2010 for the silverlight app..
Please, anyone can help me this simulated hardware keyboard works?
Thanks

and... for testing purposes.. the 177 is a Volume Key.

Maybe the problem is exist because there are no GWES keyboard driver inside system.
You should try to test it on HTC Gold or on another device with built-in QWERTY keyboard. It may work there . . .
What kind of inputs u tired already?

unfortunately i dont have any device with hardware keyboard.
I just tried keyboards inputs, with sndKbd_event() function.

If you guys have a device with built in hardware keyboard, i would like to send a app to you.. that prints all inputs detected... I want to see if there are any specifc behavior when a user "opens" the hardware keyboard.

why not. upload fully working XAP

Im uploading xap and source for it.
Its log into text box ant key event... So please. open app, and open and close the hardware keyboard. Let us see if something appears in there ! =)

I installed it on Gold. well, UI is not really clear so my observations:
1)when I slide keyboard out it seems no effect on the program.
2)when I press 'a' on the hardware keyboard "65down" and "65up" appear (0x41 is 'a' symbol) as well 'a' appear as text.
3)if I enter at the right edit box "65" and press "Send key" I see 65down and 65up, but no 'a'

the same thing happens to me too. Maybe i should make more research in wm6..
Or maybe try to simulate the inputs via "mouse pointer".. Tring to artificially press the soft keyboard.
For now I don't know how to simulate those keys .... Unfortunately.. I have no clue after all..
Thank you very much cottula. .. This means that the hardware keyboard does not send any key event when opened..
I will try to study a little more the wm6 core.
Best regards.

I've got this somewhat working, just need to figure out all the keycodes
Edit. And hiding the virtual keyboard on device would be nice too
Edit2. So I can send volume keys and such and they work, still have to get qwerty keys working so I don't have it any more working than you guys have...

For some reason.. the qwerty Keys does not works...
All KeyCodes for Windows Mobile are decribed here at this post.

Note. you must convert the HexaDecimal values in this post to a normal decimal values in order to interact with this app.
My goal here is to simulate a Hardware Keyboard.. that means, hide the softKeyboard too...

Yeah, I made a new app myself, completely in C# that runs in the background and hosts a server and I sent the keycodes from my laptop via wlan. I could use volume keys, also delete key worked and enter key worked too. Tried those in word. Figured out the key code of the back button too. So, no idea why qwerty keys won't work. Maybe we need to get the phone think that it has a external keyboard (like pageup does in the emulator)? Could cotulla get a registry dump with hardware keyboard open and closed and compare them?

We tryed using this with a phone with hardware keyboard. And this is the result.
1)when I slide keyboard out it seems no effect on the program.
2)when I press 'a' on the hardware keyboard "65down" and "65up" appear (0x41 is 'a' symbol) as well 'a' appear as text.
3)if I enter at the right edit box "65" and press "Send key" I see 65down and 65up, but no 'a'

It seems that the presence of hardware keyboard has no effect after all on app behavior. there must be another configurarion that send the correct key to the form, but i didnt know it yet.
I made a litte research on WM6.5 and there is another C++ native method to send Keys, maybe i will try them soon..
Plase. can you send me you app that already runs with background task??
Thank you !

I'll put it on github so everyone can help us figuring this out. It's pretty basic, done in Visual Studio 2008.
Ok, so the solution will be here: https://github.com/jessenic/RemoteKeyboardWP7 as soon as I've got Git extensions installed on my laptop. You can fork that and submit pull requests. I could also add you to the admins of the project if you want. I started working on toast notifications, but they need an int32 appid and I haven't figured one out yet.
Edit. Committed. Maybe the keyboard ID is wrong? WinCE7's keybd_eventEx's last argument is the keyboard ID.

Is the time between the sending and the receiving of the enter, or del key, big? Or is it quick?

Instant (at least on n-series wlan)

I 've tried all IDs from -1000 to 1000.. .. without sucess...
I have no ideas left...

Code:
#define KeyStateDownFlag 0x0080
#define HWND_GLOBAL (HWND)0xFFFFFFFF
void EmulateKey(BYTE bKeyCode, BOOL up)
{
keybd_event(bKeyCode, 0, KEYEVENTF_SILENT | (up ? KEYEVENTF_KEYUP : 0), 0);
}
void EmulateWchar(wchar_t wSymbol, BOOL up)
{
UINT uKeyFlags = up ? 0 : KeyStateDownFlag;
UINT uKeyCode = (UINT)wSymbol;
PostKeybdMessage(HWND_GLOBAL, 0, uKeyFlags, 1, &uKeyFlags, &uKeyCode);
}
// example
int _tmain(int argc, _TCHAR* argv[])
{
EmulateWchar(L'T', FALSE);
EmulateWchar(L'T', TRUE);
...
}

Thanks, but still can't get it working Could you have a look at it here: https://github.com/jessenic/RemoteKeyboardWP7/blob/master/RemoteKeyboard/Program.cs
the SendKeyboardKey(byte) works fine, but the SendKeyboardString(string) does not
Btw, have you noticed what code 122 does to the virtual keyboard! (Symbol (SYM) key.)
Edit: I get Invalid pointer error message from PostKeybdMessage :/

Works perfectly ! Thanks !!!
jessenic .. i cannot open your server project.. What i should do ?
I have vs 2008 but i cannot open this... And it doesnt seems to be any wp7 app... what it is exataly?
