Question

how do i count the number of rows that are affected when I updated a table, and display the number of affected rows in a message box ??

here is my code for updating the table …

    For Each row As DataGridViewRow In DataGridView1.Rows
    req = row.Cells(Column1.Name).Value
    If row.Cells("Column1").Value = True Then
        Dim sql2 As String = "UPDATE EquipmentDetail SET Requested = '" & req & "' WHERE SerialNumber = '" & serials & "'"
        cmd2.Connection = connection
        cmd2.CommandText = sql2
        cmd2.ExecuteNonQuery()
    End If
Next
connection.Close()

End Sub

help would be appreciated … thanks

The executeNonQuery method returns the number of affected rows. Just use that number and show in a message box.
