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.

You can download any files that you need to follow the video here.

You can increase the size of the video:

Full screen mode for YouTube

Changing resolution

You can improve the resolution of the video using another icon at the bottom right of the frame. This will slow down the connection speed, but increase the display and sound quality. This icon only becomes visible when you start playing the video.
