>ExecSprocScalar if used in a mmbusiness object is an mm method. The IdbDataParameter[] is a collection of parameters. You can add as many parameters as needed to support your stored procedure. You can use the mm method of this.CreateParameter("@paramName", value) as many times as needed sperated by commas to fill that collection.

How exactly IdbDataParameter[] and Param1,Param2 correspond - this is the problem I'm not exactly getting. I know it works, but how C# knows to translate value1, value2 into array of values?

In VFP that will not work, for example.
