Sending messages to minimized Winamp Window

[patheticpat]

Hello,

I am currently writing a small plugin that lets me control Winamp with the mediakeys of my Acer Notebook. I am registering a global hook that intercepts the commands and sends appropriate messages to Winamp:

code:
LRESULT CALLBACK MyShellProc(int nCode, WPARAM wParam, LPARAM lParam)

{

  ...      

  if (nCode == HSHELL_APPCOMMAND) {

    short AppCommand = GET_APPCOMMAND_LPARAM(lParam);

    switch (AppCommand) {

      case APPCOMMAND_MEDIA_NEXTTRACK:

        PostMessage(_plugin.hwndParent, WM_COMMAND, WINAMP_BUTTON5, 0);

        return 1;

      case APPCOMMAND_MEDIA_PLAY_PAUSE:

        // similar code for other commands

    }

  }

  ...

}

This is working fine as long as Winamp isn't minimized into the system tray. Why does it stop working? The window should still process the messages I am sending . Any help on this would be appreciated.

Problem solved: In order for this code to work the plugin has to live in a shared segment of the DLL.
