Solution 1

You don't need a Hook to filter events coming to a editor control (as this is MFC, did you mean CEdit?). You can do it all processing messages.
Please see this example:

Solution 2

You could also achieve this with a masked edit control, such as CMFCMaskedEdit[^] or maybe COXMaskedEdit[^].

Can be a better alternative, in some cases much better, depending on what are the constraints for the text to be input. My 5.
