补充：

The NewWindow2 event

The NewWindow2 event occurs when a new window is to be created for displaying a resource. This event occurs before a new window is created from the WebBrowser control. For example, this event occurs in response to a navigation that is targeted to a new window or to a scripted window.open method.

To specify that your browser program is to be used when a new window is opened, set the ppDisp parameter equal to a new WebBrowser object that is contained in a new window that your program creates. In this scenario, if a user chooses to open a Web page in a new window, the new window in your program is used to display the new Web page.

Additionally, set the RegisterAsBrowser property to TRUE. This setting causes the new WebBrowser control to participate in window-name resolution. For example, if the window name is used elsewhere in the script, this control is used instead of a newly created one because the control examines all the existing window names before opening a new window.
