Problem with VB.NET using MySql.Data.dll Reference

Question

Hello all, I'm facing problem with applying the MySql.Data.dll file in Reference of my VS 2003. When I try to add in,I saw a prompup and show this Error Message:

A reference to' C:\Documents and Setting\Visual Studio Projects\Test\MySql.Data.dll' could not be added. This is not a valid assembly or COM component. Only assemblies with extention 'dll' and COM components can be referenced. Please make sure that the file is accessible, and that it is a valid assembly or COM component.

Anyone could guide me how to solve this problem?

Thanks for reading~!
