[SOLVED] Detecting keyboard shortcuts in WinForm swallowed by host mfc accelerators

Detecting keyboard shortcuts in WinForm swallowed by host mfc accelerators

I have a MFC MDI app which defines Ctrl-F as a keyboard accelerator. This app hosts a WinForm dialog. My problem is I want to catch Ctrl-F from this child WinForm dialog but the MFC mainframe seems to be swallowing it.

I can detect other keyboard shortcuts in the WinForm dialog, if they are not defined in the accelerators table
If the edit dialog was MFC too, I think I could define and load an accelerator for this dialog too, and then use ProcessMessageFilter
in WinForm i've tried both overriding ProcessCmdKey and listening KeyDown events to no avail

Do you think there is a way to receive those key press in the WinForm child?

Solution

I've found a solution that works. When showing the c# WinForm, use the overload

Form.Show(IWin32Window owner)

and pass the MFC mainframe Hwnd as the owner. Now everything is working as expected.
