no message in PreTranslateMessage()

if you use it in ActiveX context, then it is expected behaviour.

for non MFC extension DLls same problem....

 

 

Anyway. for 10.4 release we replace method from PreTranslateMessage to OnWndMsg to be sure it will call fro ActicveX/ simple DLL contexts. please patch your sources.

 

BOOL CXTColorPicker::OnWndMsg(UINT message, WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
 if (!m_bPopupActive)
 {
  if (message == WM_LBUTTONDOWN)
  {
   ShowPopupWindow();
   // in this case the message is not "swallowed" so the button will
   // get it and display itself in a recessed state
  }
  else if (message == WM_KEYDOWN &&
   (wParam == VK_RETURN ||
   wParam == VK_SPACE ||
   wParam == VK_DOWN))
  {
   ShowPopupWindow();
   return TRUE;  // swallow message
  }
 }

 return CXTButton::OnWndMsg(message, wParam, lParam, pResult);
}
