MFC主线程仅关注Dialog，需要处理从服务器接收的数据

Question

My code will receive xml data from server, the data quite huge. after finishing receiving the xml data from sever, my code want to continue to parse the xml data, however, I have no idea why the thread focus on the dialog to receive message from system to paint or do something else... NO WAY TO go back to the parsing code. however, if i close the dialog, it will go back the parsing code automatically?

what is the problem? please help me.....

Answer 1

从Internet上获取数据时，对话框的上载消息正在消息循环中挂起。因为您说的是大数据，所以它挂起了您的应用程序。所有其他消息都放入了消息队列。一旦您的应用程序从挂起状态返回，所有消息最后出现在对话框中的WM_PAINT消息也处于挂起状态，该消息在挂起条件完成之后且在读取xmle文件之前执行。

You will need to perform the "receive and parse xml data" in a separate thread if you need the dialog to be responsive during that time.

Use CreateThread() to start a thread, you can check if the thread has terminated (and get the exit code of the thread) using GetExitCodeThread() .

Alternatively, you can use the MFC CWinThread class to do the same thing.
