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

Posted by Andrew Gould on 31 March 2016

Excel VBA Forms Pt 4 - Validating Controls

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.

See our full range of VBA training resources, or test your knowledge of VBA with one of our VBA skills assessment tests.

This video has the following accompanying files:

Hi Wise Owl,

Great training video as always - the best training videos bar none! Look forward to any future videos.

I wanted to ask if you also use 'KeyPress' and 'KeyDown' to validate controls and what your opinion is on using that method?

Thanks.

Thanks Michael, happy to hear that you've enjoyed the videos!

I'm afraid that I don't have any particular insight on the KeyPress and KeyDown events as I don't tend to use them. To me it's always seemed like overkill to test each keypress for the systems that I've worked on!
