• maddman Restarting Windows

  I need my program to be able to restart the computer. However, when I copied the code off of http://support.microsoft.com/default.aspx scid=kb;en-us;176695, but when I run, I get a PInvokeStackInbalance run-time error at the OpenProcessToken line.

Someone know how to do that you place the code where you want the operation to run in your application. Again im pretty sure that the idea you have will not work in ASP.NET but rather more of a Winforms application running in the background or a background service. Or even create a Windows scheduled task running a batch file to rename the file. you can ask more about this to see if it will run in an ASP.NET application ...Show All

• Kelandom When should I call dispose()?

  No problem, let us know if you run into any issues! Usually, it's best to call dispose() on an object when you are done with it. This will allow the object to clean up resources as soon as it can. I recommend using the "using" keyword when interacting with disposable objects; see the following: http://msdn2.microsoft.com/en-us/library/htd05whh.aspx Here is a general document on when to dispose on objects, and how the disposable pattern works: http://msdn.microsoft.com/library/default.asp url=/library/en-us/cpgenref/html/cpconfinalizedispose.asp Thanks timothy ng for the information, i will study them ;-) ...Show All
