In Visual Studio 2008, you can flag threads that you want to give special attention. Flagging a thread marks it with a flag icon in the Threads window, so that flagged threads can be easily distinguished from other threads.

Flagged threads also receive special treatment in the Thread list on the Debug Location toolbar. The Thread list can be set to show all threads or only flagged threads. When you flag a thread, the Thread list automatically switches to show only flagged threads. You can switch it back to show all threads when you need to.

To flag a thread in the Threads window

  • In the Threads window, right-click the thread you want to flag and click Flag.

    If the thread is already flagged, the Flag option does not appear.

    —or—

    Click the disabled flag icon in the leftmost column of the Threads window.

To unflag a thread in the Threads window

  • In the Threads window, right-click on the thread you want to unflag and click Unflag.

    If the thread is not flagged, the Unflag option does not appear.

    —or—

    Click in the enabled flag icon in the leftmost column of the Threads window.

To flag a thread in a source window
