>>>Hi,

>>>Sorry - missed this message. Don't use Update command. Here's an example that you should be able to adapt. VFP SPs:
PROCEDURE SetUserName

>>>FUNCTION WhoIsCurrentUser
>>>  RETURN UserName
>>>ENDFUNC

       static void Main(string[] args)

>>>
>>>            // Now see if the public variable is accessible by SP
>>>            System.Data.OleDb.OleDbCommand test = new System.Data.OleDb.OleDbCommand();

May be I'm wrong, but I think in CommandText you can only specify the SP name and you have to pass your parameter through Parameters collection of the Command object.
If it's not broken, fix it until it is.
