thanks for your help.
I'v installed a global hook in a DLL(SetWindowsHookEx(WH_GETMESSAGE,
(HOOKPROC)GetMsgProc, g_hInstDLL, 0);), but can't catch the message of
WM_SHOWWINDOW(I use XP +VC6.0,there is no definition of WM_SHOW),
this is the callback function:
LRESULT CALLBACK GetMsgProc(int nCode, WPARAM wParam, LPARAM lParam)
   FILE* stream;
 TCHAR sFilename[MAX_PATH]={0};
 int n_count;
    PMSG p=(PMSG)lParam;
     DWORD m_PID;
     HANDLE m_handle;
   m_handle=OpenProcess(PROCESS_ALL_ACCESS, TRUE, m_PID);
   n_count=GetModuleFileNameEx((HMODULE) ;
   stream = fopen( "c:\\sys_fopen.txt", "at" );
        fclose( stream );

forcing the window to become invisible. This means you have to detect the
splash screen,
which is most commonly a modeless dialog with the desktop as a parent, but
whose owner is
the main window of the app. You could use Spy++ to look at its
