I don't believe you can use ADO.NET out of VBA. You'd have to write an
managed add-in for Excel using VS2005/VB.NET/VSTO.

I was used to use OLEDB connect to SQL Server from Excel 2003. I want
to know is it possible to have Excel 2003 support ADO.NET 2.0? If
possible, what kind of library should I install? where can I get it?

Thanks
