HWND Handle = NULL;

Handle = FindWindow("NotePad", NULL);
if(Handle != NULL)
{
// e.g for running
ShowWindow(Handle, SW_SHOWNORMAL);
PDLRTAllowSetForegroundWindow(NULL, NULL, NULL);
SetForegroundWindow(Handle);
}
else
{
// e.g for not running
ProgramExecute("NotePad.exe");
Handle = FindWindow("NotePad", NULL);
SetWindowPos(Handle, HWND_TOPMOST, 10 , 425, 1000, 200, 0);
