Either write a filtered edit control (i.e. a control that does not accept certain characters) or filter the string as soon as the user hits "ok" and show him an error, if you find any characters in that field. With std::strings you could use the .find-family of operations. You could, optionally, .remove any characters that you find unsuitable and then write the result back to the editbox, with a message-box for the user showing what he did wrong.

I suggest either use a masked edit control, or handle the
ON_ENCHANGEnotification. If any 'invalid' characters are found in the edit control, disable the OK button.
