how can I create an edit box with : in the box

[Danielle Harvey]

I have a dialog box with an edit box for time in the box. I can fix the length of the edit box to 5 characters, but how can I fix a semi-colon within the edit box so that the user can change the hour or the minutes, but she or he can't delete the semicolon. I saw this technique in a ms program where the user inputs the social security number as xxx-xx-xxxx and the user can't delete the dashes.

I appreciated any type of response, especially an an example as to how to implement this.

Hi.

You have two options.
1) Use Masked Edit control(?) of ActiveX control.
2) Derived your own EditBox class and use OnChar().

Hope for help.

Hi, you should take a look to CodeGuru-Edit control section, there you'll find a lot of good example how to do it.
