Validation of CEdit control

[debugee]

My problem is that i want to validate the contents of a CEdit control which is being created and destroyed, and i pop up a MessageBox if the contents of the CEdit is not the correct one. I validate it in KillFocus of the CEdit control which causes a second return in the KillFocus when the MessageBox pops up.
So if anybody has any ideas, please let me know.
Thanks

I normally do all validation for edit boxes when the user clicks OK - if anything is invalid, display a message box and do not call the CDialog::OnOK() so the dialog stays open.

If you want to validate as the user is typing, catch the keystrokes using the PreTranslateMessage() function.

Well I cannot check anything on th OnOk, cause I have to check (validate) the contents of the edit field when it looses focus (or when it is being destroyed).
