I am writing an application for my Notary business. I know I can use the Text Box Base class to cover the Text Box and also the Masked Text Box, but my validation code is not doing anything. I have an Error Provider on the form called Error Provider. So, I figured I would use the Validated and Validating events of the controls. This is my code: Private Sub Company_Validated(By Val sender As Object, By Val e As System. Combo Box (that can be modified), Text Box and Masked Text Box. I need to make sure the "required" fields have a value when the Save button is clicked. If I leave the control empty, still nothing happens.

Adi Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. See the How to Ask page for help clarifying this question.You will work with some controls that perform all checking automatically, requiring no code.You will also create a custom validator with code that you write, which illustrates how you can add your own logic to the validation framework in the page.I have a small project for school and I can't figure out why I'm getting this error when validating inputs.For example, I'm checking if the input is valid and between a min and max range by creating a function to return a true or false value based on the values entered.
