List Control, Key Trapping

[williegofar]

Hi,

I have a list control object. Within that object I want to be able to trap key presses to allow other processes to 'kick off'. I have been able to get this to work via the LVN_KEYDOWN message.

My problem however, is that is that I don't want the list control to also carry out it's normal process in response to such a keypress. In other words, if I have an entry in my list 'ABCD' and the user presses 'A', I don't want anything in the list to change, at present the selection changes to highlight the 'ABCD' record. Anyone got an idea on how to prevent this?

Thanks.

You could try to intercept the WM_KEYDOWN messages by hooking the windows procedure of the listbox.

Thanks for the reply.
I'll go and find some info about hooking (like what is it!, lol)

Check out SetWindowsHookEx for that....
