I'm trying out VB.NET for the first time, and I'm trying to upgrade an old VB 6.0 project. I'm having a problem with events that reference other events. It gives me this upgrade warning:

Code:
'UPGRADE_WARNING: Event cmbCategory.TextChanged may fire when form is intialized. 
'Click for more: 'ms-help://MS.VSCC/commoner/redir/redirect.htm?keyword="vbup2075"'
Which is all well and good. Going to the help file gives you the nice suggestion to add a property called IsInitializing on the form and do something like this:

Code:
Private Sub Check1_CheckStateChanged(ByVal sender As System.Object, _ 
ByVal e As System.EventArgs) Handles Check1.CheckStateChanged
   If Form1.DefInstance.IsInitializing = True Then
      Exit Sub
   Else
      TextBox1.Text = "Check1 was clicked"
   End If
End Sub
But the help file compleatly fails to mention how to implement the IsInitializing property. Can anybody help me out here?
