• Visual Basic Setting form time out to exit if idle for xx minutes?

  Hi, Does someone have a code snippet or reference page that illustrates the use of a form timer or variable to be set that allows one to set a limit on an open form to close after a period of time if no activity has been done.  I want to close/exit a form if the user has not entered or clicked a field for, lets say 15 minutes.  If there has not been any activity then close the form and return back to the main form.   Thank you from a newbie.

• Visual Studio Team System TFS Source Control - Get Latest not working properly - Files are not marked ReadOnly

  A couple problems with TFS Source Control. 1. Sometimes when getting latest, it will tell me that I have lots of conflicts because there are writable versions of a file in my working folder. I go and look and the file attributes are marked with an "A" instead of "R". This happens a lot and some of the files I never even worked on. Is there some way I can re-get everything from source control to overwrite all my files with the "R" readonly flag flipped. This also causes a problem when I try to edit one of these files that doesn't have the "R", it doesn't ask me to check it out. It seems quite random ...Show All

• Visual Studio Express Editions Power control of windows: How to reboot and wake from hibernate/standby?

  Hi everyone: I have only found system.windows.forms.application.setsuspendstate method could make system into standby or hibernate state, but I don't know how to reboot the system via .net method.
