How to restore missing controls in Visual Studio 2008 Toolbox

I encountered a problem today when I tried to use Visual Studio 2008.

When I created a Windows forms project, the controls in Toolbox were missing. The usual remedy of right-clicking the Toolbox and then selecting Reset Toolbox did not help.
