Good Day Experts!

I have a DataTable only contains 1 record.  In the past, I have only used for each loop to process the DataTable.  

For Each sqlRS In sqlRStbl.Rows

Next

How can I just get the row from the DataTable?

Thanks,

     sqlRStbl.Rows(0)  (use [0] insead of (0) in C#)
else
    'WOULD HAVE THROWN AN ERROR.  REPORT IT.
end if

does this loop give you errors?

For Each sqlRS In sqlRStbl.Rows

Next


It shouldn't. If it does, do like ged325 suggested:

Dim dr as DataRow
dr=sqlRStbl.NewRow()
If sqlRStbl.Rows.Count > 0 Then
      dr=sqlRStbl.Rows(0)
End If
 

Open in new window


I was not sure where you wanted to store the results so i used a DataRow

Thanks for replying. I was not getting an error with the loop.  I had always processed DataTables with a ForEach loop.  But this DataTable is only being populated with 1 row of data.  I just never knew how to interrogate the DataTable for only 1 row.

 This all stems from when I was using a DataReader that I couldn't close before calling a subroutine.  I passed the subroutine the connection string used by the DataReader and was trying to execute a DataReader on that same connection and was getting an error.  So, I converted the DataReader to a DataTable in the calling routine to alleviate the problem.  

Thanks for the help,
