Hello!

I am trying to get a list of all the process running on WinCE. I first
developed my code on NT (which is working fine) and now I am porting it to
WinCE 4.20. I am using embedded Visual C++ 4 SP2.

My problem is that the callback function is called only once and my program
crashes. No exception seems to be thrown. Do you have some suggestions on
what may be the problem?

My code looks like:

BOOL CALLBACK _EnumProc(HWND hwnd, LPARAM lParam);

void DrvOpen(void)
{
BOOL bFoundProc = FALSE;
...
EnumWindows(_EnumProc, (unsigned long)&bFoundProc);
...
}

BOOL CALLBACK _EnumProc(HWND hwnd, LPARAM lParam)
{
BOOL bContinueEnum = TRUE;

TCHAR pszCaption[2048];
char szProcName[2048];
static unsigned int uiCallCounter = 0;

GetWindowText(hwnd, pszCaption, sizeof(pszCaption));

wtoa( pszCaption, szProcName, 2048 );
_TraceLog( szProcName, FALSE, FALSE ); // bCheckLastError, bOverwriteFile

....

return bContinueEnum;
}

Thank you in advance!

Frederic.

Frederic,

A shot in the dark...

Is the stack allocation large for a CE device perhaps?
TCHAR pszCaption[2048];
char szProcName[2048];
This:

GetWindowText(hwnd, pszCaption, sizeof(pszCaption));
Click to expand...

ought to be:

GetWindowText(hwnd, pszCaption, 2048/*_countof(pszCaption)*/);
