in reply to Ideas for implementing pShell

I got tired of seing 20 cmd.exe windows in my taskbar, so I set out to steal them. This is my proof of concept (what you want to focus on is Win32:: and EVT_ calls )

While experimenting with this I wanted a way to map processes to top level windows, this is about as good as it gets

    Great! This is useable code for this project! PodMaster++

    Using Perl to help the disabled: pVoice and pStory
      Another thing I've just discovered is that you cannot wrap
      Win32::API::->Import( "user32", "DWORD GetWindowThreadProcessId( HWND hWnd, LPDWORD lpdwPr +ocessId)" ) or die $^E;
      in a begin block. If you do, it won't work properly. For example if you tried GetWindowThreadProcessId($handle, $procid); $procid would not be populated with the process id as is expected. This drove me crazy 10min ago.

      update: also, be sure the new parent window has wxCLIP_CHILDREN on, otherwise flicker galore
