How to handle "window.Close" JS in a WebBrowser in c#

I have to code a program for a library, I have to embed a Web Browser for a website but the Web Browser can’t be close. So I have cancel closing but when a user clicks on a button in JS for closing window (window.Close) the program crash. I add :

HtmlDocument htmlDocument = this.webBibliotheque.Document;
htmlDocument.Window.Unload += new HtmlElementEventHandler(Window_Unload);

when the Document is charged. This code works and gets to catch the evenment but I don’t know what I have to do in my function :

void Window_Unload(object sender, HtmlElementEventArgs e)
{

}

Can anyone help me please?

You should handle the WindowClosing event on the underlying WebBrowser ActiveX Control (WebBrowser.ActiveXInstance). There is an option to cancel it (disclaimer: untested). Check this answer for more details on how to handle the "raw" WebBrowser events like this.
