*******大家再来看看，模式对话框与非模式对话框的差别问题********
在控件里create一个窗口，想截获键盘Escape键，该怎么办？
我在控件的*ctl.cpp文件和mydlg.cpp文件都重载了pretranslatemessage函数，好象在前面一个函数里刚刚启动的时候截获过一次，以后就一直没有了，如果把窗口domodal出来的话，就没这个现象。好象是因为焦点失去的缘故。该如何处理，成功给分。
注：控件在ie里运行

reason:
ie UI thread does not trans ESCAPE event to your window.
when you use dialog , dialog use it's own thread.
a common window(not dialog) use thread which call CreateWindow(Ex)
to solve your problem
1.
hook WM_KEYDOWN or WM_NCKEYDOWN in current process(IE).
2. before create window, first create a thread, in this thread, call Createwindow . you should code like following in this thread
CreateWinodw....
ShowWindow
UPdateWindow
MSG msg
while ( GetMessage(&msg,NULL,NULL,NULL,NULL)
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}

那非模态的消息是怎么循环的呢？

模态对话框有自己的消息循环,所以行
countrynew 2002-05-18
有点明白了，呵呵~~~

这个你不会不知道吧! 非模态的对话框没有消息泵,所以不能响应消息. 此时的消息循环仍在主界面窗口
如果要,周期性地调用PeekMessage(...),再处理消息
