I have a dialog window that contains a CRichEdit control used for chat input.  There are a number of other controls in the window but none require input from the user.   Some of these 3rd party controls steal the focus from the edit.  I want all keys to go to the richedit.

Specifically, you can override the PreTranslateMessage function in the derived CDialog class for your dialog box to handle the keyboard messages.

Then you can test the incoming messages for keyboard events, such as WM_KEYDOWN, WM_KEYUP, and WM_CHAR.  Then you can send those messages to the specific control you want (using PostMessage or SendMessage) and return TRUE to let the message loop know you handled the message.

For example, something like:

BOOL CYourDialog::PreTranslateMessage( MSG* pMsg)
{
  switch(pMsg->message)
  {
    case WM_KEYDOWN:
    case WM_KEYUP:
    case WM_CHAR:
      m_rcheditControl.SendMessage(pMsg->message, pMsg->wParam, pMsg->lParam);
      return TRUE;
      break;  //for style;
     default:
      break;
  }
  //handle normally
  return CDialog::PreTranslateMessage(pMsg);
}

Neither of these comments is correct actually.  I had to call SetFocus prior to passing the message.
