>I had some C# code a while back to hide the tabs on a TabControl. Anyone know how to do this? Google search results all involved removing and re-adding the tabs. IMHO, it's utterly ridiculous that MS didn't include a visible property on the individual tabs.

You can remove a TabPage (to later re-add it). Have a look at http://www.emoreau.com/Entries/Articles/2004/05/The-incomplete-TabControl.aspx and http://dotnetrix.co.uk/tabcontrol.htm
