Allowing Enter in hotkey control

Question

I'm using the standard hotkey control to allow user to specify a key combination for a certain action. However, it doesn't allow using the Return (Enter) key. Is there a way to allow it? My action is sort-of chat reply, so having a hotkey like Alt+Enter makes the most sense.

Answer 1

The only way would be to sub-class the control, since by default it rejects keys like VK_RETURN.

Your sub-class would probably need to do two things:

• Handle the WM_GETDLGCODE message and return DLGC_WANTMESSAGE when the message indicates the enter key has been pressed
• Handle the WM_KEYDOWN message when return is pressed, and manually set the hotkey in the control by sending it a HKM_SETHOTKEY message.
