本文探讨了在Windows环境中创建窗口与使用等待函数时应注意的问题。特别指出直接或间接创建窗口的线程必须处理消息，避免使用无超时等待函数导致系统死锁的情况，并推荐使用MsgWaitForMultipleObjects或MsgWaitForMultipleObjectsEx替代WaitForSingleObject。

Use caution when calling the wait functions and code that directly or indirectly creates windows. If a thread creates any windows, it must process messages. Message broadcasts are sent to all windows in the system. A thread that uses a wait function with no time-out interval may cause the system to become deadlocked. Two examples of code that indirectly creates windows are DDE and the CoInitialize function. Therefore, if you have a thread that creates windows, use MsgWaitForMultipleObjects or MsgWaitForMultipleObjectsEx, rather than WaitForSingleObject.
