Question

pretty new to vb and I want to get a tab control working.
so far I have the form with a tab control on it, there are 5 tabs each with a label contained in the tab-page.
I want to have a button outside of the tab that changes on the form. when clicked the button will change the text of the label based on which tab is currently selected. I know it should be possible to do this, I’m not too sure where to start.

You need to find the label control back on the active tab page. The cleanest way to do this is to create an array that has a reference to each label. Like this:

Public Class Form1
    Private Labels() As Label

    Public Sub New()
        InitializeComponent()
        Labels = New Label() { Label1, Label2 }
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Labels(TabControl1.SelectedIndex).Text = DateTime.Now.ToString()
    End Sub
End Class
