当前窗口接收不到SOCKET线程消息问题

Question

当SOCKET接收到数据时在SOCKET线程中能向当前对话框发送SendMessage消息，(已在对话框中映射了消息)
但Domodal()建立一个新对话框后确收不到消息.
直到退出建立的新对话框时消息才被上一个对话框收到.
请各位高手帮忙，是何问题如何解决？

Answer 1

1.
Cpub::ActivehWnd是否是有效的窗口
2.
是否对WM_REROOMTYPE进行了消息映射,原型是否正确
3.
SendMessage=>PostMessage

Answer 2

Cpub::ActivehWnd是有效窗口，WM_REROOMTYPE也进行了映射,现在的情况是本来应该在当前窗口接收数据再发送消息的，但线程不知道什么原因好象是在上一级窗口那阻塞了

Answer 3

有多个消息是分别映射到多个对话框的.
目前的问题是SOCKET要退出Domodal()出来的对话框，才能在线程函数中收到数据

Answer 4

多线程之间最后用postmessage不用sendmessage

Answer 5

是线程没能转到新对话框上，Domodal后线程函数就被阻在对话框外边了

Answer 6

不要用Domodal() 用create()就可以了
