The below code returns  Object variable or With block variable not set.
at  
dgResults.DataSource = objDataReader

What does this mean?


code.....
 ' Set up our connection.
                Dim objConnection As SqlConnection
                objConnection = New SqlConnection("Server=localhost;Database=customers;UID=sa;PWD=go;")
                objConnection.Open()

                'Specify the SQL string
                Dim strSQL As String = "Select First_Name,Last_Name from USERS_TBL WHERE ID=" & strUserID2 & ""
                'Create a command object
                Dim objCommand As SqlCommand
                objCommand = New SqlCommand(strSQL, objConnection)

                objCommand.ExecuteNonQuery()
                'Get a datareader
                objDataReader = objCommand.ExecuteReader(CommandBehavior.CloseConnection)

                'Do the DataBinding
                dgResults.DataSource = objDataReader
                dgResults.DataBind()
                getFirst = objDataReader("FIRST_NAME")
                getlast = objDataReader("LAST_NAME")
   
                getuserinfo = getlast & "," & getFirst

The error is still showing up and has something to do with
dgResults.DataSource = objDataReader

Try this instead of the DataReader:
Dim adapter As SqlDataAdapter = new SqlDataAdapter()
adapter.TableMappings.Add("Table", "USERS_TBL")
adapter.SelectCommand = cmdSuppliers
Dim ds As DataSet = New DataSet("Users")
adapter.Fill(ds)
 
dgResults.DataSource = ds
dgResults.DataBind()

Open in new window
