datagridview not populating...

I am certain this is a dumb problem, but I cannot find it.  

I am trying to populate a datagridview (dgv) in WinForms.  

I define my query sSQL = "select * from Table", I open my connection.  Then I am running the following code:

            sdaB = CurrentDB.ExecuteAdapter(sSQL); //Returns sqlDataAdapter --CurrentDB is a DataClass
            DataTable dtB = new DataTable();
            sdaB.Fill(dtB); //On this line, the code seems to stop (jumps to form view) no other lines are run.
            dgvB.DataSource = dtB;

As I mention above in the comments, the code runs to .Fill line and when I step that line of code, I jump to the Form view and the code stop.  The dgv is not populated.  I am stumped.  I know this is supposed to be simple.  

I have tested my sql statement, and my connection.  Both seem to be valid (there is data there).  

Any suggestions on why the code will not execute on the sdaB.Fill(dtB) line?
