Never use your Input unfiltered. Put the Textbix1.Text Input in a integer.tryparse construct. Also, activate Option strict for better code quality.

For your Problem:

Dim MaxVisible as Integer
Dim Sucess as Boolean
Sucess=Integer.Tryparse(textbox1.text, MaxVisible)
If Sucess=True

For index As Integer = 9 To MaxVisible  + 1 Step -1
 Me.TabControl1.TabPages(Index).visible=false
End If

That should make the unwanted tabcontrols invisible. I dont know if Tabpages(index) works, maybe you must youse getitems instead - I have no Winforms Project at hand to test it. More Information on TabControl: http://msdn.microsoft.com/de-de/library/system.windows.forms.tabcontrol.aspx
