Hi Experts,
I use about 10 Combobox controls in my VB.Net application. The controls names all begin with "cboResult".  I want to loop through all my Combobox controls whose name begins with "cboResult" and add "Yes", "No", and "N/A" as possible selection values (i.e. Items.Add("YES"), etc...).  How can I do this?

Thanks in advance,
mrotor

Try something like...
Public Class Form1

    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        FindCombos(Me)
    End Sub

    Private Sub FindCombos(ByVal cont As Control)
        For Each ctl As Control In cont.Controls
            If ctl.Name.ToUpper.StartsWith("CBORESULT") AndAlso TypeOf ctl Is ComboBox Then
                Dim cb As ComboBox = DirectCast(ctl, ComboBox)
                cb.Items.Add("YES")
                cb.Items.Add("NO")
                cb.Items.Add("N/A")
            ElseIf ctl.HasChildren Then
                FindCombos(ctl)
            End If
        Next
    End Sub

End Class
