Introduction
I designed a text box control while I worked in Visual Basic 6.0. I found it very useful as it uses a very good validation logic.
Developers can specify the criteria of validation and the text box will follow the criteria.

It has all the properties as a standard text box. It has some additional properties. They are as follows...
AllowedChar: This property will force the validation logic to allow the characters specified here.IlligalChar: This property will force the validation logic not to allow the characters specified here.
IlligalChar has more precedence than AllowedChar.Format: User can specify a pre-defined format for the text box. The available choices are as follows..
