This feature needs to be tested in this exact sequence, including the time taken for the user to input data, server response time, etc. In this case, the Explicit Wait will wait for the pop-up to appear before proceeding with the test. However, since the test cannot wait an infinite ...

After starting the tasks, the DoWork method uses theWaitAny(array<WaitHandle[], TimeSpan)method overload to wait for the shortest subtask to finish, with a 250-millisecond time-out to report progress to the user interface. TheBackgroundWorkerthen uses the WaitAll(array<WaitHandle[...

I guess firewalling issues, but you did change a few things now for your deployment. You could try the office again? And those legacy applications... Are the client/server based? Can you create remote apps from them using RDS? Where is the fileserver data, are you moving to Teams? So...

push函数里,先根据data值创建新节点,然后要把它放到堆顶 因为是用链表实现的栈,所以,如果新节点要成为新的堆顶(相当于新节点作为新的头结点插入),那么新节点的next域要指向原来的头结点,并让head指向新节点 `new_node->next = head.load`把新节点的next域指向原头结点,然后`head.compare_exchange_weak(new_...
