VB 6 String Handling

Earlier you learned about the string data type. The VB 6 language has many functions to handle string types. In this article, we will present the list of those functions with examples.


There are two types of strings in VB 6 programming.

  • Variable length strings
  • Fixed length strings

To declare variable length string you can use following syntax.

'variable length string declaration
Dim myStr as String  
'fixed length string declaration
Dim myFixedStr as String * 20

You can notice that we are using asterisk (*) to specify the length of the string which is 20 characters.
