iTask development need help with dll files

Hi! I'm pretty stuck with developing more useful things for iTask so I'm entering the dark and dangerous world of c++.
I don't know anything about eMbedded VisualC++, so I hope someone here can help me get some more information out of the ppc, like free memory, storage, signal, etc, if it is easy and possible.
The flash command to read this is "GetPowerStatus". So that must be changed to something new in the script.
Hopeful for any answer!
This is the sample file that comes with bryht flashapp for importing battery percent info. It works.
if you need the evc files as well please post.
Here's the script:
#include "stdafx.h"
#include "plugin.h"
BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}
const char *g_command[] = {
"GetPowerStatus",
NULL,
};
SETVARIABLE SetVariable = NULL;
FLASHAPPPLUGIN_API const char** WINAPI RegisterCommand(SETVARIABLE pSetVariable)
{
SetVariable = pSetVariable;
return g_command;
}
FLASHAPPPLUGIN_API int DoCommand(HWND hWnd, const char*cmd, const char*params, int argc, char* argv[])
{
if( _stricmp( cmd, "GetPowerStatus" ) == 0 )
{
#ifdef _WIN32_WCE
SYSTEM_POWER_STATUS_EX sp;
memset( &sp, 0, sizeof(sp));
GetSystemPowerStatusEx( &sp, TRUE );
#else //for windows desktop version
SYSTEM_POWER_STATUS sp;
memset( &sp, 0, sizeof(sp));
GetSystemPowerStatus( &sp, TRUE );
#endif
//send the value to Flash
char value[32];
sprintf( value, "%d", sp.BackupBatteryLifePercent );
if( argc>0 && argv[0]!= 0 )
SetVariable( argv[0], value );
}
return FLASHAPP_OK;
}

}
But on the Device emulator this doesn't work. It allways returns PHONEDEVICE_ERROR.
Could someone please tell me what i'm doing wrong?
I've been trying to get this to work for 2 months now, but still no luck
Thanks in advanced,

problem with injection DLL to specified process

Save me from madness!!!
I have a several smartphone devices with windows CE
CE 6.0 - hp IPAQ 500 series
CE 5.0 - Samsung i600
I need to inject DLL into the process "home.exe". I use method with performcallback4 function. This method works successfully for all processes ("device.exe", "service.exe", etc.) except process "home.exe". In what a problem?
source code : InjectDLL.exe link with toolhelp.lib
#include <windows.h>
#include <Tlhelp32.h>
typedef struct _CALLBACKINFO {
HANDLE hProc;
FARPROC pfn;
PVOID pvArg0;

}

the error code is
#define STATUS_INVALID_PARAMETER_MIX 0xC0000030
(maybe too fast for getting the thread infos?)
try to make the "Sleep(500);" before "PerformCallBack4(&ci);"

I have tried, a problem not in it. Any ideas?

I have not found the reason.... I Use other method without performcallback4

Problem with injection dll to cprog.exe process?

Anyone can help me? Sorry for my poor english.

which compiled errorfree
Added the registry entries as shown above, copied the launcher's exe in default location, rebootet device. Nothing happened, means executable defined as

wasn't run at all.
Does anybody have an idea, where the error is? Any help appreciated. Thanks for reading.
