Highlighting text when tabbing

When my form loads, I want zero's in some of my textboxes (these are numeric fields that the user seldom inputs data into). I would like the zeros to be highlighted when the user tabs to that textbox so that the zero will be replaced by the user's input when they begin to type. Is there an easy way to do this?

Thanks,

Place this code in the GotFocus event (obviously change TextBox to the appropriate name).

TextBox.SelStart=0
TextBox.SelLength = Len(TextBox.Text)
