WebBrowser filetype

Hello,

I've got a question:
I've got a WebBrowser control in my form, but when I navigate I wan't to check the filetype to download any files that aren't displayable in the webbrowser(e.g. zip files etc.) but how do I retrieve that filetype and how do I check it. Tried it within the navigating event handler but it didn't work.

Any suggestions would be great.

Thanx in advance,

Bas Tuijnman
