To add to Ajay's comments... you'll need something like this code

BOOL CMainFrame::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message == WM_KEYDOWN) {
  if(pMsg->wParam == VK_F1) {
    // Do something
    return true;
   }
  else if (pMsg->wParam == VK_F2) {
    // Do something
    return true;
   }
}

// Let the default handler handle this key
return __super::PreTranslateMessage(pMsg);
}

Hello, I have a CFrameWnd (well, actually a class that inherits from it)
with one CButton and one CEdit. I need my CFrameWnd to perform some things
when F1 or F2 is pressed. Thus I have an entry for ON_WM_KEYDOWN in my
message map and have my own OnKeyDown. However, sometimes the CEdit or the
CButton may have input focus (well, maybe not the CEdit, the user cannot
type in it or place a cursor on it), so my question is: what is the proper
way for those child windows to pass these key presses, if they occur, to
their parent window? I guess could simply have the same logic in my child
windows to detect keypressses and if F1 or F2 is pressed, simply call the
parent, but is that the proper way to do this?
