当应用程序看起来是空闲时，实际上它在运行函数： C Wi n A p p : : R u n ( )。该函数不仅具有

查询新消息的逻辑功能，并且完成了大量包括更新用户界面状态和清除临时内存对象在内的

应用程序维护工作。因此，如果需要在应用程序中的某个地方停止运行并等待消息，也需要

进行这种应用程序维护工作。由于微软提供了C Wi n A p p ( ) : : R u n ( )函数的源代码，因此本例将

创建该函数的一个新版本，可用于应用程序中的任何地方-When the application appears to be idle, in fact, function in the run: C Wi n A pp:: R un (). The function of news is not only query the logic function, and including the completion of a large number of state and update the user interface object to get rid of Temporary memory applications, including maintenance. Therefore, if the applications need somewhere to stop running and wait for further news, but also the need for maintenance of such applications. Because Microsoft provides a C Wi n A pp ():: R un () function of the source code, so in this case the function will create a new version of the application can be used anywhere
