>I am using ADO to access SQL server stored procedures. In aprevious thread I asked for help on calling these stoted procedures with parameters. Well I have worked that out now - thanks to surgey who gave me a link to a documents. I can access these procedures and send parameters to them, but how do I assign the returned record set to the CA? I want to be able to navigate through the record set and use the returned values with textboxes,grids etc.
