The representation of the unsigned intToday, I encountered a bug when I wrote the heap sort. void builMaxHeap( int *arr,unsigned int heapSize){ unsigned int i; for(i=heapSize/2-1; i>=0;--i){ std::coutistd::endl; //maxHeap(arr,i,heapSize); 这里暂且注释掉 } } This is really the whole dead man, thought it was the wrong program, the output of the result isHehe, can only hehe, the reason is

For simple interactions, the service can use the WTSSendMessage function to display the message window on the user Session. For some complex UI interactions, you must call CreateProcessAsUser or other methods (such as WCF and. NET remote processing) for cross-Session communication and create an application interface on the desktop user.WTSSendMessage Function If the service simply sends a message window to the desktop user Session, you can use the WTSSendMessage function. First, add an Interop.
