On my application I have an edit box in which the user enters a string.  I need to be able to tell within the OnChangeEditBox function what the last key the user pressed was, especially whether it was the delete key.

If anyone has any ideas I would be extremely grateful.  Thanks!

You should subclass CEdit and create a new CMyEdit box or subclass the current CEdit control.
Then map WM_KEYUP to your CMyEdit and save the message value into a global or static variable.
Later , in your OnChangeEditFunction(),you'd check the variable to get what key was just released.


Free to ask.

Btw:You can also store it in PreTranslateMessage(),first check if it's WM_KEYUP and store it.

Looks a great way to go about it.
However I found an easier method suitable for my application.

thanks
