带ActiveX控件的窗口的销毁问题！高手帮忙看看！
我在CDialog中添加一个Web Browser Activex控件,实现了在OnNewWindow2可以打开新窗口
新窗口是通过new myDialog() 等方式创建，可以在新窗口打开先前窗口点击的页面。
问题：
在关闭新打开窗口后，需要对刚才 通过New创建的窗口对象进行销毁：
销毁代码：
先Navigate2(_T("about:blank");
等DocumentComplete后
在SendMessage(WM_CLOSE)关闭窗口！;
在对其窗口DestroyWindow();
但是在 DestroyWindow时出现如下错误：

[解决办法]
用PostMessage(WM_CLOSE)试试
