Detect Return keypress in a edit text widget

Edited text of question

Widget means what ?

Thank You!

This Edit box is in a child window dialog, It does not response to "OnOK". Would you please be more detailed about using derived class from CEdit and process WM_KEYDOWN, WM_KEYUP. to catch a "Return" key press.

Thank You!

Try this out ...

In your derived CEdit class, say CMyEdit, add an handler for PreTranslateMessage ...

BOOL CMyEdit::PreTranslateMessage(MSG* pMsg)
{
  if ((pMsg->message == WM_KEYDOWN) && 
      (pMsg->wParam == VK_RETURN))
       .... CALL YOUR FUNCTION (Enter has been detected)
       return TRUE;// Saying that you have handled the msg
  }
  return CEdit::PreTranslateMessage(pMsg);
}

You can also translate your key strokes to some other key stroke.
For Ex: If Enter needs to be treated as Tabs, you can do the following ..

BOOL CMyEdit::PreTranslateMessage(MSG* pMsg)
{
  if ((pMsg->message == WM_KEYDOWN) && 
      (pMsg->wParam == VK_RETURN))
       pMsg->wParam = VK_TAB;// Cheating !!
  }
  return CEdit::PreTranslateMessage(pMsg);
}

Hope this helps

Thank You!
