In your project, you need to Add a Reference and point it to the .Net Assembly (DLL). You'll probably need the proper Using statements (assuming C#) in your code files.

>Connection and sqlexec()s handled by a separate dll so it can be used by multiple apps. Need the foundation base form to call and see the results. Don't want a call from every field so how to make the results visible to all of the lower classes when the call is made to a separate dll (which will pass the query to SQL Server and return a result set). I am probably overlooking something very basic and obvious. In VFP, we had a class or a prg (depending on the version) which we called and passed to it the query and the result set was returned. It was duped in another app for its use. This time, we want a separate utility to handle the communication to/from sqlserver which all apps can use.
