Excel VBA User Forms videos | Excel VBA Forms Pt 4 - Validating Controls

Posted by Andrew Gould on 31 March 2016

Validation is all about making sure a user has entered sensible values in a control. This video shows you how to use the before- and afterupdate events of a textbox to prevent a user continuing when they've entered invalid data. You'll learn how to check if a value is a number or a date and how to modify the properties of controls at runtime to indicate that there's a problem.
