[RESOLVED] How to read values from a datatable?

[gggram2013]

Hi, I know this seems very simple, I have the datatable filled with the records and all i want is to increment it. My code looks like this:

SqlDataAdapter da = new SqlDataAdapter(cmd);                
                //this is creating a data table
                DataTable dt = new DataTable();
                int invNum = da.Fill(dt);

               invNum = invNum + 1;

Is this code correct?
