在TabControl vb.net中查找重点突出的文本框

Question

I'm trying to add a TabControl to my text editor. I just need to find out how I can find the current textbox the user is editing in the tab control, so a button changes the current selected tab's text to "Hello World". The button is not located inside of the tab control.

Below is my code for adding a new tab to the tab control, it runs on a button click.

Dim tpTabs As New TabPage()
    Dim tbText = New TextBox()
    tpTabs.Name = "tpPage" & tcTabs.TabPages.Count + 1
    tbText.Name = "tbText" & tcTabs.TabPages.Count + 1
    tbText.Multiline = True
    tbText.Dock = DockStyle.Fill
    tbText.ScrollBars = ScrollBars.Both
    tpTabs.Text = "Untitled"

    tpTabs.Controls.Add(tbText)
    tcTabs.TabPages.Add(tpTabs)
    tcTabs.SelectedTab = tpTabs

So every tab opens with a new textbox. New tabs are called "tpPage" followed by a number that increments one every time a new tab is made, same with textbox, "tbText" followed by a number that increments every time a new one is created.

So I want my button to change only the current tab's text currently opened to "Hello World!," then the other tabs when I get to them eventually.

Any help is appreciated, I've tried many things like TcTabs (which is the tab control on the form) tcTabs.SelectedTab.tbText.Text = "Hello World!," but I can't find a solution.

CType（tcTabs.SelectedTab.Controls.Item（0），TextBox）.Text =“ Hello World”
