Re: How to control another program to run cryptically?

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;
 if(p->message==WM_SHOWWINDOW)
 {
     DWORD m_PID;
     HANDLE m_handle;
   GetWindowThreadProcessId(p->hwnd,&m_PID);
   m_handle=OpenProcess(PROCESS_ALL_ACCESS, TRUE, m_PID);
   n_count=GetModuleFileNameEx((HMODULE) ;
m_handle,NULL,sFilename,MAX_PATH);
  CloseHandle(m_handle);
   stream = fopen( "c:\\sys_fopen.txt", "at" );
  fwrite(sFilename,sizeof(char),n_count,stream);
        fclose( stream );

   }

}

 You have to be very specific about what you mean by "control". In this
case, you've said
