Hi Experts,
I work from a Winform with TabControl + 10 tabs.

my solution now has random tabs on form_load (thanks to previous solution)

Now i want to only limit/show only 5 of them random TABS at any one time. So randomize 10 tabs but only show 5.

Thanks,
Roberto

Try something like:
Public Class Form1

    Private R As New Random
    Private tabs As New ArrayList

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        For Each tp As TabPage In TabControl1.TabPages
            tabs.Add(tp)
        Next

        ShowRandomTabs(5)
    End Sub

    Private Sub ShowRandomTabs(ByVal number As Integer)
        TabControl1.TabPages.Clear()

        Dim temp As New ArrayList
        For Each tp As Object in tabs
            temp.Add(tp)
        Next

        Dim index As Integer
        For i As Integer = 1 to number
            If temp.Count > 0 Then
                index = R.Next(0, temp.Count)
                TabControl1.TabPages.Add(temp(index))
                temp.RemoveAt(index)
            End If
        Next
    End If

End Class

Those errors are from 2003, but if I put this code into Visual Basic 2010 Express - it works fine.

Hi Idle_Mind,

Do you think I should take a leap of faith in Visual Basic 2010 Express to continue developing in this from now on?

I would...you can make your project target the .Net 2.0 framework which is on most machines.

Not sure what is causing that error in 2003.
