How to call that function ? Add the code below the constructor: class form ...     form constructor (details of the form, size, etc.)     all the objects on the form     usually a statement like:     form.rowset = ...     // add all your own code here:     function MyValidation        bReturn = true        // whatever you need to do        // set return to false if invalid     return bReturn endclass Then in the code in the form if you want to perform the validation routine you can do it in things like an onLostFocus event handler, and call:   class::MyValidation() like:     if not class::MyValidation()        alert( "Something is not valid" )        this.focus()     endif There are MANY ways to do things like this. If you haven't, you may want to look at my books, and/or the dBASE Tutorial (see my signature block below).
