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.

Description

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..
• fmtText: Any text is allowed.
• fmtAlphabetic: Only alphabets are allowed.
• fmtAlphaNumeric: Only alphabets and numeric characters are allowed.
• fmtUnsignedNumeric: Only unsigned numbers are allowed.
• fmtSignedNumeric: Only signed numbers are allowed.
• fmtUnsignedFloat: Only unsigned float is allowed.
• fmtSignedFloat: Only signed float is allowed.
• TextCase: User can specify the text case. The options are as follows:
• Normal
• Sentence
• lowercase
• UPPERCASE
• TitleCase
• tOGGLEcASE
