Validation starts with Validator1, Validator2 and finally Validator3.You can assign one of these properties or all of them if you need to perform multi-level validation.For example you can require the input for text-box and enforce the format to be an email by assigning Validation1 and Validation2 properties.Select control you want to assign validation to and change its Validator1 property to choose desired validation type.In such cases, you can force the controls in the support library to behave more closely to the original VB6 controls by setting the VB6Config.Focus Event Support static property to True: When this property is True, the support library ensures that the Lost Focus event is always fired after the Validate event.

Text = "") End Sub Now consider the corresponding VB. If the end user clicks on a different control and Text1 contains an empty string, the Lost Focus event resets the background color to white, then the Validate event cancels the focus shift, and finally the Got Focus event changes the background color to yellow again. If this is the case, the converted code might fail or behave unexpectedly.If you have something in particular that you would like to see explained here, you could reach me at [email protected] Strawmyer (MCSD, MCSE, MCDBA) is a senior architect of .Next step is to choose the way Super Validator performs validation.That is done by setting Validation Type property as shown in image below: These properties allow you to define 3 level validation for each control.
