C# MDI Parent detect when MDI Child is closing?

问题 I'm attempting to detect, on the MDI parent, when my MDI child form closes, and react accordingly. The MDI parent shouldn't do anything until the MDI child closes. Here is my code, I'm unsure as to what I'm doing wrong, but the form closed event method I added is never being called...

问题 I am trying to implement a simple web browser control in one of my apps. This is to help integrate a web app into a toolset i am creating. The problem is, this web app absolutly loves popup windows.... When a popup is opened, it opens in an IE window which is not a child of the MDI Container form that my main window is part of. How can i get any and all popups created by clicking links in my WebBrowser to be a child of my MDI container (similar to setting the MDIParent property of a form)?
