I am building an application using Windows Forms (VB.Net 2003).

I need to disable some pages of a tab control depending on users privileges. It seems that the Enabled property disable the content of the tabpage and not the access to the tabpage.

Then I found http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbtskdisablingtabpagesprogrammatically.asp which is using the SelectedIndexChange to detect when a tab is selected and switch to another.

There are 2 things that I don't like about this:
1. There is a visual flicking. How can we stop the flicking?
2. There is no visual clues that the tab is not enabled. How can we gray the caption of the tab page?

Or if you have better ideas please tell me!
