TFS中强制取消签出

If one member of your team has checked out the file without checking in and you want to edit the file, you can check the file in by this way:
C:\Program Files\Microsoft Visual Studio 8\VC>tf undo /workspace:UWORKSPACE;USER /se
rver:USERVER  $FILEPATH
And pay attention plz, the change of the file by the member will not be save at the server.
Also you should be a administrator of the system.
