.NET snippets and books: Tabcontrol event called at odd time

Tabcontrol event called at odd time (Wednesday, September 22, 2004)

Found the following interesting discussion in the Newsgroups:

tabcontrol event called at odd time by:Anonymous
Hello, I'm curious as to why the following would happen. I have 4 forms that I'm dealing with. On form4 is a tabcontrol (we'll call it tab1). When form1 is opened, and OK is pressed, form2 opens, when an item is clicked, form3 opens. On form 3 is a menu, and when file, open, and form4 is selected, the tab1_SelectedIndexChanged event is triggered... I have code in here to deal with when users select different tabs...but why would opening the form trigger it? Obviously I only notice it when I step through the code...is this normal?? Thanks in advance, amber

	Hi hmm yes its normal try this if you dont want it to triger on load ------------------------------------ Dim isLoad As Boolean = False Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load isLoad = True End Sub Private Sub TabControl1_SelectedIndexChanged(ByVal _ sender As Object, ByVal e As System.EventArgs) _ Handles TabControl1.SelectedIndexChanged If isLoad = True Then MsgBox("ok") End If End Sub ----------------------------------- /Jens
