Hi.. and hello..
could i ask you all a question? i had a problem.

situation:
=======
the input box cannot grab the NULL value (blank).

My own solution (but not solve):
====================
i'm try make try and catch. let's see my code..

Code:
Private Sub GetData()
        Dim row As Integer = DataGridView1.Rows.Count
        Dim N As Integer
        N = 0
        N = InputBox("Enter the number of order :")
        Try
            N = DBNull.Value <----------------- here the problem (maybe)
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
            Dim jumlah As Decimal
            jumlah = Decimal.Round(N * txt_harga.Text).ToString("f2")
            Me.DataGridView1.Rows.Add(row, kodMakanMinum, txt_foodDrinkName.Text, N, jumlah)
    End Sub
when i try to compile..i will get error
Code:
Error:Value of type 'System.DBNull' cannot be converted to 'Integer'.
can you show me a "hack" to use null / blank ? to read it and catch the err0r ?
