hello experts . . .
i've designed a form (two textboxes and one commandbutton)
i wanna display id and user(fields of the table). and i display id and user on the basis of the id(inputted through textbox1).And for that i've written following code within command button's click event
Private Sub Command1_Click() con.Provider = "Microsoft.Jet.OLEDB.4.0" con.Open App.Path & "\db.mdb" Dim query As String query = "select * from tbl where id=" & Val(Text1.Text) rec.Open query, con, 2, 3 Me.Text1.Text = rec!id Me.Text2.Text = rec!user con.Close Set con = Nothing End Sub
i manually inputted data to the table (i inserted value to id field only and user field remained blank).
and now whenever i click on command button to retrieve data it produces an Error saying "Invalid use of Null".
Now what i want is when there is nothing in the user field then i wanna display the value "0".
so any solutions . . .
