title: Launching external exe in MFC, how can I bring exe to front if already opened?
body: <p>I have to open up a external program in my MFC application, which works but if I have already clicked button, I don't want it to open another instance but just bring it to front.  The docs say the SW_SHOWNORMAL parameter does this, but it is not working for me.  Does the called program have to setup for this also?</p>
  
  <p><code>ShellExecute(NULL, "open", "C:\Test\blahblah.exe", NULL, NULL, SW_SHOWNORMAL);</CODE></p>
  
  <p>Thanks,
  CP</p>
