[TOOL/WinCE]CeSetBacklightLevel.exe - Windows Mobile Apps and Games

Thought I should share a little tool I wrote.
Abstract:
Changes Windows CE's backlight level on the fly, no warm boot required. It's a command line utility without an UI.
Requirements:
CE device with ARM processor.
Usage:
CeSetBacklightLevel.exe <intensity>
Example: CeSetBackLightLevel 100
MortScript example: Run("CeSetBackLightLevel.exe",100)
Download:
Source code and executable are attached to this post.

nice, could this with a mort script be used to set back-light according to the hour of the day ?

That exactly was the reason I made this tool.

can you help me make a loop in mortscript to check the time of the device and compare it to a look-up table that has the intensity of the screen for some periods of time ?

In Windows CE we can't use Mortscript's RunAt command.
Perhaps somewhat like this:
Code:
If (FileExists("\Windows\CeSetBacklightLevel.exe"))
If(RegKeyExists("HKCU","ControlPanel\Backlight\Brightness")||RegKeyExists("HKCU","ControlPanel\Backlight\Backlightlevel"))
PollInterval = 1000 * 60 * 10 // 10 minutes
StartTime = 630 // 6:30AM
EndTime = 2130 // 9:30PM
WantedBacklightLevel = 100 // Hex: 64
While(1)
CurrentHour = 0
CurrentMinute = 0
CurrentSecond = 0
CurrentDay = 0
CurrentMonth = 0
CurrentYear = 0
GetTime ( CurrentHour, CurrentMinute, CurrentSecond, CurrentDay, CurrentMonth, CurrentYear )
TheTime = CurrentHour * 100 + CurrentMinute
If ((TheTime >= StartTime) && (TheTime <= EndTime))
CurrentBacklightLevel = -1
If( RegKeyExists("HKCU","ControlPanel\Backlight\Brightness"))
CurrentBacklightLevel = 0 + RegRead("HKCU","ControlPanel\Backlight\Brightness)
ElseIf( RegKeyExists("HKCU","ControlPanel\Backlight\Backlightlevel"))
CurrentBacklightLevel = 0 + RegRead("HKCU","ControlPanel\Backlight\Backlightlevel")
EndIf
If(CurrentBacklightLevel >= 0)
If (CurrentBacklightLevel <> WantedBacklightLevel)
Run ("\Windows\CeSetBacklightLevel.exe", WantedBacklightLevel)
EndIf
Else
// error occurred
Exit
EndIf
EndIf
Sleep(PollInterval)
EndWhile
EndIf
EndIf

I haven't had the oportunity to test it on my 2din. Has anyone tested the code ?

Hi there,
should this tool work on Becker TA 7827?

Hi, could someone tell me how to compile the C code jwoegerbauer published?. I have Visual Studio 2008 Pro, but do not know how to get an WinCE .exe.
I want to make some changes, because this utility does not work for me. My unit is a GPS Car, WinCE 6.0 NWD_308 Nowada Board, and I have problems with brightness. This:

Thank you.

Nice, hope will get an .exe
@jwoegerbauer did you implement the loop in miopocket lite ?

As compiler I use Pelles C - it's freeware. Supports compiling native C-code for ARM devices.

1.
You know that you can't compile a MortScript script into an executable? If you really need an executable, then you have to re-write the code sample shown earlier in 'C' or any other suitable programming language a compiler exists for.
2.
Don't use Miopocket Lite, hence not tested so far. BTW: Some time ago I've written MioPocket 4.0 Mini FV and published here:

Hi, jwoegerbauer.
Thanks for the info. I now have installed Pelles C and I can compile simple things. Abusing your kindness, could you tell me what program lines I need to write to generate a beep? I think MessageBeep, but the compiler takes Error
I am a newbie and I want to check your code to see why it does not work exactly in my unit.
Thanks again !!!

There are a number of functions from the Standard C Runtime libraries missing under Windows CE.
But, MessageBeep API function should be present.

Thanks again, jwoegerbauer. With your help I made my first program in C (for Windows CE). Instead of the classic "Hello World", I made a Beep. This can be useful to use as debug semaphore. This is the code, for compile with Pelles C in WinCE Pocket PC Mode:
#include <windows.h>
int PASCAL WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPWSTR lpszCmdLine, int nCmdShow)
{
MessageBeep(MB_OK);
return 0;
}
I used the MessageBeep in your code.
HANDLE hBL=CreateEvent(NULL,FALSE,FALSE,L"BackLightChangeEvent");
if(hBL)
{
MessageBeep(MB_OK);
SetEvent(hBL);
CloseHandle(hBL);
retVal=1;
}
And really, the program executes the SetEvent (HBL). But does not work on my GPS car WinCE 6 .

A question, jwoegerbauer.
I tried downloading your MioPocket Mini 4.0 FV from here: https://miopocketmini40fv.codeplex.com/releases
But the project is empty. Can you tell me where to I can download it (or send me by email), I have interest in trying it.
Thanks.

I'm looking for a similar program, but for the MIPS processor, discussed this?
