Cycling through forms 1

[artyk]

Hi,all. I'm developing an app that needs to add/remove controls on the fly to accomodate additional records. I added a numerical identifier to the "tag" property so that I could identify how many records there are, but I'm not sure how to cycle through the controls to find the highest "tag" value.

Basically, I need to search the form and get the control with the highest "tag" so I will know ho many controls need to be added/removed from the form.

Any assistance would be greatly appreciated.

Here's an example.

    Private HighestTag As Integer = 0
    Private HighestControl As Control
    Private Sub FindHighestTag(ByVal ctl As Control)
        For Each c As Control In ctl.Controls
            Try
                If Convert.ToInt32(c.Tag) > Me.HighestTag Then
                    Me.HighestTag = Convert.ToInt32(c.Tag)
                    Me.HighestControl = c
                End If
            Catch ex As Exception

            End Try
            FindHighestTag(c)
        Next
    End Sub

Test it by calling the following:

        FindHighestTag(Me)
        MessageBox.Show("Highest Control = " + HighestControl.Name + " with Tag of " + HighestTag.ToString)

Thanks. I'll work with it and configure it for my code and see what happens. Thanks again for your help.
