I have a edit control that I only want to accept numbers.  I have subclassed this control and captured the WM_KEYDOWN events but how do I keep the edit from displaying anything but numbers??  I used Spy++ but I didn't see any kind of paint messages sent when I typed in text.

In the resource editor, open the properties of the CEdit control you're using and check the 'numbers' checkbox. Also, create a variable of a control type via the wizard for any dialog that uses this control and set it to your subclassed version.

I do not see a "number" option under the resource editor.  Also this is a, dare I say, 16 bit app.

What version of VC are you using? I assume 4.xx but I don't have that. In 5.0 it's in the properties dialog of the control on one of the tab sheets. Not sure if it's available in 4 but it should be.
