在WIN32中，每一个线程都对应着一个消息队列。由于一个线程可以产生数个窗口，所以并不是每个窗 口都对应着一个消息队列。下列几句话应该作为"定理"被记住： "定理" 一 所有产生给某个窗口的消息，都先由创建这个窗口的线程处理； "定理" 二 Windows屏幕上的每一个控件都是一个窗口，有对应的窗口函数。消息的发送通常有两种方式，一是SendMessage，一是PostMessage(In WIN32, each thread corresponds to a message queue. Since a thread can have several windows, so not every window corresponds to a message queue. The following words should be a " theorem" to be remembered: " Theorem" all produce a message to a window, all threads initially create the window treatment " Theorem" Two Windows on the screen is a control for each window, there is the corresponding window function. Messages sent are usually two ways, first, SendMessage, PostMessage first)
