Refuse to Sleep/Hibernate if recording feature, Has it gone missing? Options

[mikebliv]

I'm quite sure this feature was there before but the latest version allows me to sleep/hibernate the machine (Windows 7) while in the middle of recording. The feature still works for shutdown.

Any idea what happened to it?

Guys,

To further clarify with quotes from msdn http://msdn.microsoft.com/en-us/library/aa373208(VS.85).aspx

The ES_AWAYMODE_REQUIRED value should be used only when absolutely necessary by media applications that require the system to perform background tasks such as recording television content or streaming media to other devices while the system appears to be sleeping.

To enable away mode, an application uses both ES_AWAYMODE_REQUIRED and ES_CONTINUOUS; to disable away mode, an application calls SetThreadExecutionState with ES_CONTINUOUS and clears ES_AWAYMODE_REQUIRED. When away mode is enabled, any operation that would put the computer to sleep puts it in away mode instead. The computer appears to be sleeping while the system continues to perform tasks that do not require user input. Away mode does not affect the sleep idle timer; to prevent the system from entering sleep when the timer expires, an application must also set the ES_SYSTEM_REQUIRED value.

Example:

CODE

// Television recording is beginning. Enable away mode and prevent
// the sleep idle time-out.
//
SetThreadExecutionState(ES_CONTINUOUS | ES_SYSTEM_REQUIRED | ES_AWAYMODE_REQUIRED);

//
// Wait until recording is complete...
//

//
// Clear EXECUTION_STATE flags to disable away mode and allow the system to idle to sleep normally.
//
SetThreadExecutionState(ES_CONTINUOUS);

The SetThreadExecutionState function cannot be used to prevent the user from putting the computer to sleep. Applications should respect that the user expects a certain behavior when they close the lid on their laptop or press the power button.

Says it all.
