Hey There,
    I have been writing some code in C++ that gets a message from a
Macromedia Flash Player to launch an application that is associated
with a flash button. When the button is pressed, it launches the
application, but the app window is never completely in front. The C++
code that I have been using to do this is below:

        retVal =
CreateProcess(NULL,modName,NULL,NULL,FALSE,NULL,NULL,NULL,&si,&pi);
        hProc = pi.hProcess;
        procID = pi.dwProcessId;
        HPStruct.procID = procID;
        HPStruct.WindHandle = 0;
        fp = fopen(THREAD_LOG_FILE,"a+");
        fprintf(fp,"ProcID=%d\n",procID);
        fclose(fp);
        WaitForInputIdle(hProc,INFINITE);

EnumWindows((WNDENUMPROC)EnumOpenWindows,(LPARAM)&HPStruct);
        fp = fopen(THREAD_LOG_FILE,"a+");
        fprintf(fp,"After EnumWindows \n");
        fclose(fp);
        if(HPStruct.WindHandle != 0)
        {
            ShowWindow(HPStruct.WindHandle,SW_SHOWMAXIMIZED);
            retVal = BringWindowToTop(HPStruct.WindHandle);
                }

         Is there something with the flash player that stops the app
from being in front? When I have other windows open and launch the app,
it will always be in front of any other window BUT the flash player
window. Any suggestions?

Thanks,

Also,
  For some reason, the EnumWindows Function:

BOOL CALLBACK EnumOpenWindows(HWND hwnd, LPARAM lParam)
{
    DWORD dwID;
    DWORD currProcId;
    FILE* fp;
    struct _HwndProcStruct* locHPStruct;

    fp = fopen(THREAD_LOG_FILE,APPEND_MODE);
    fprintf(fp,"*******************<EnumOpenWindows>*******************\n");
    fclose(fp);

    locHPStruct = (struct _HwndProcStruct*)lParam;
    currProcId = locHPStruct->procID;
    dwID = 0;

    GetWindowThreadProcessId(hwnd, &dwID);

        fp = fopen(THREAD_LOG_FILE,APPEND_MODE);
        fprintf(fp,"currProcId=%d dwID2=%d\n",currProcId,dwID);
        fclose(fp);

    if(dwID == currProcId)
    {
        locHPStruct->WindHandle = hwnd;
        fp = fopen(THREAD_LOG_FILE,APPEND_MODE);
        fprintf(fp,"FALSE\n");
        fprintf(fp,"*******************</EnumOpenWindows>*******************\n");
        fclose(fp);

        return FALSE;
    }
    else
    {
        fp = fopen(THREAD_LOG_FILE,APPEND_MODE);
        fprintf(fp,"TRUE\n");
        fprintf(fp,"*******************</EnumOpenWindows>*******************\n");
        fclose(fp);

        return TRUE;
    }
}

The above function never returns the hwnd associated with the procID
that is the ID from the created process. Any ideas?
