The Crystal folks just don't get it when it comes to using stored procs.  If you've ever tried to get tech support from them on this problem you would quickly come to the same conclusion. :)

Anyway, one of the biggest problems with Crystal is that is stores the server/database info in the Report file, and you're out of luck trying to use the same report against different databases or servers by altering the settings in code.

You have to re-verify the database settings against each server/database from within the Crystal Reports Designer UI.

What you're probably seeing is not that you're getting previously saved data with each run of the report, but that it's always going against the server/database hard-coded in the Report file, rather than what you are setting thru code.

There is one way to fool it into doing what you want, and it involves having the Crystal Engine create a new DSN on the fly for the appropriate server/database connection using the LogOnServer method of the Print Engine.  Then you have to iterate through the Tables collection within the Report.Database object and reset the Location property with the database/table info.

Nasty stuff.  I lost quite a few hairs over geting Crystal to work.

Why not have VB run the stored procedure and receive the recordset from the database?  You could then pass the recordset to Crystal and have it just display the results.
