// Change priority...
/////////////////////////////////////////////////////////////////////

// 1) to change your application's priority:
	BOOL b=::SetPriorityClass( 
		::GetCurrentProcess(),		//process handle
//		REALTIME_PRIORITY_CLASS // highest: thread must run immediately before any other system task
//		HIGH_PRIORITY_CLASS		// high: time-critical threads
//		NORMAL_PRIORITY_CLASS 	// normal: thread with equal importance to other system applications
		IDLE_PRIORITY_CLASS 	// low: threads that can run in the background of the entire system
		);

// 2) To get the current priority:

	DWORD priority=
	  ::GetPriorityClass(
		::GetCurrentProcess()		//process handle
		);
