Thanks, but this does not work:

   if(pMsg->message==WM_KEYDOWN)
   {
      if (GetKeyState(VK_CONTROL)==1)
      {
         if (pMsg->wParam=='a')
         {
            MessageBox("Ctrl+A");
            return TRUE;
         }
      }
   }

I never run in the GetKeyState==1 clause.
What's wrong?

Hello NG,

how can I check in PreTranslateMessage, if the user has pressed Ctrl and

if(pMsg->message==WM_KEYDOWN)
  {
     pMsg->wParam; //?? Ctrl+A ?
     pMsg->lParam; //?? Ctrl+A ?
  }

Thanks for help,
Guido

The wParam will contain 'A', and you can check the state of the Ctrl key
(at the time the WM_KEYDOWN message was generated; this is important!) by
using GetKeyState.
