I'm studying the basics of VB6 programming, but the manual doesn't give a clear example of how to make a message box pop up ON FOCUS.
I have 2 text boxes, number1 and number2, which equal textbox numbersum. If numbersum = 0.5 or greater, I want a message box to pop up when that text box becomes focused.
Please tell me how to do this.

Many thanks.
