Many Datatypes supportedin .NET are not supported in VB6. But, then you can write custom functions or procedures to get the same. I need to work on it before giving u solution. If anyone elase gives it, thats great.

It's like converting to Hex which is base 16, but to base 64.
In the same way that Hex has to use letters to represent digits, so does Base 64.

But, as I understand it, the sequence doesn't start with 0 to 9 and then extend with letters, but just starts with A=0, B=1 up to Z = 25. Then come the lower case letters, then the 10 digiits and finally + and /.

I'm sure that with that information a person of your calibre can code an equivalent in VB6
