Reboot & sleep loop in Windows Vista

[Dashken]

Well, I want to start to pick up on programming again.

I wish to create a tool for stress testing Windows Vista system through running reboot or sleep in a definite loop which will increase a counter upon each reboot/sleep&wakeup completed.

Anyway I can do that? I hope someone can point me to somewhere for more info.

Thanks.

I think you can write a batch script of a vb script that does that, and also make it a part of you boot up sequence <-- not such a good idea cos you wont be able to boot up to windows without getting rid of that script from the run level

Hmmm sounds like you'd need to invoke the windows API to get it to restart. increment counters should not be a problem. it will just be reading and writing to a text file. that's the simplest method to keep track of the number of runs.

once u program this application, run it as a startup program.

As to where and how, Hmm i can try to find it but you'd probably have to refer to the latest MSDN for Vista's APIs.

looks like the API u need to invoke is ExitWindowsEx()

I think this should do most of what you want to do.

#include <windows.h>

/*------------------------------------------------------------------------
 Procedure:     SystemReboot ID:1
 Purpose:       The SystemReboot function either logs off the
                current user, shuts down the system, or shuts down
                and restarts the system. This is layer function
                to ExitWindowsEx. It ask necesory privilege under
                WinNT.
 Input:         Mode - Specifies the type of shutdown.

                EWX_LOGOFF Shuts down all processes running in the
                security context of the process that called the
                ExitWindowsEx function. Then it logs the user off.

                EWX_POWEROFF Shuts down the system and turns off the
                power. The system must support the power-off feature.

                EWX_REBOOT Shuts down the system and then restarts
                the system.

                EWX_SHUTDOWN Shuts down the system to a point at
                which it is safe to turn off the power. All file
                buffers have been flushed to disk, and all running
                processes have stopped. If the system supports the
                power-off feature, the power is also turned off.

                EWX_FORCE Forces processes to terminate. When this
                flag is set, the system does not send the
                WM_QUERYENDSESSION and WM_ENDSESSION messages. This
                can cause the applications to lose data. Therefore,
                you should only use this flag in an emergency.
 Output:
 Errors:        If the function succeeds, the return value is
                nonzero. If the function fails, the return value is
                zero. To get extended error information, call
                GetLastError.

Wow... thanks everyone! Appreciate it. Now, I have to dig deep and find any programming skills that I've still got left.
