ADODB.Stream: Error--Invalid class String

Hi all,

I am using Microsoft Visual Interdev to write/develop ASP code. Refering to code below, when I tried to create object of class "ADODB.Stre am", an error was reported by IIS/ASP error engine stating "invalid class

Cod
---------

set testObject = Server.CreateOb ject("ADODB.Str eam"

When I used 'testObject.' in Microsoft Visual Interdev software, all the related methods and variables were listed in front of me. This means that some how ADODB.Stream is registered somewhere but IIS/ASP engine is unable to find it.

Can somebody tell me what can be actual reason?? Could it be registry problem?? Should I re-register that class?

If I have to re-register that class, then from where I will get the DLL file of that class?

Thank
Mohit Gupta
