怎么样使用SendMessageTimeout()函数确认窗口未响应，最好有源程序，我已经昏了，
什么也想不出来！！！！！ :~~

The SendMessageTimeout function sends the specified message to a window or windows. The function calls the window procedure for the specified window and, if the specified window belongs to a different thread, does not return until the window procedure has processed the message or the specified time-out period has elapsed. If the window receiving the message belongs to the same queue as the current thread, the window procedure is called directly — the time-out value is ignored.

是不是让你调用得处理过程在发一个处理完毕得消息呢！

设定一定的超时值，超时后函数返回0值，此时可以断定此进程以无响应，因为他没有办法继续处理收到的消息。
此函数对自己进程内的窗口无效，因为消息不进队列，直接发给了窗口消息处理函数。
