preventing vista shutdown loggoff API showing

Question

I want to stop the shutdown / log off API which appears when you have programs open to confirm a shutdown/logoff.

I have an application already that send a reason to the API.

I know this is bad practice but I really need to override / cancel the shutdown with out displaying the API after 5 seconds.

is there any way to hack this or run a custom shutdown script to override the shutdown.

thanks in advance

Answer 1

You may want to look at this: http://msdn.microsoft.com/en-us/library/aa376871(VS.85).aspx

When I did this functionality I had to do everything in unmanaged C++ as I had problems trying to set the priviledge by using Interop.

You need this flag: EWX_FORCE in ExitWindowsEx.

Answer 2

it doesnt matter about holding it for5 seconds just catching it if it is pressed once. I can do that but vista shows a API screen after 5 seconds which All i want is vista not to show that.

vista shows that because I prevent it from shutting down.
