Question

I have two comboboxs, one is used to control another. So in the AfterUpdate event of the combo_1, I do a requery for combo_2 to force it to update its list according to the value chosen in combo_1. But my code doesn’t.

Private Sub combo1_AfterUpdate()

Dim strSQL As String

Select Case Me.combo1.Column(1)
    Case "Production"
        Me.combo2.Visible = True
        strSQL = "SELECT id_prod FROM tblProd;"
        Me.combo2.ControlSource = strSQL
        Me.combo2.Requery
    Case Else
        Me.combo2.Visible = False
End Select

End Sub

There is nothing in the combo_2 when i choose “Production” in combo_1. The requery clause is executed but no effect.

Answer 1

Unless the syntax has changed in later version you should change the line

Me.combo2.ControlSource=strSQL

To

Me.combo2.RowSource=strSQL

Try that because otherwise it looks good
