Re: [Mono-list] About the thumbnail creator
Replace wc.LoadUrl(args[0]); by wc.LoadUrl(url); and maybe, it will works better when the url is not provided as the first argument. Checking that url is not null before proceding may also be useful when you forget to provide an Url.

Re: [Mono-list] About the thumbnail creator
When I launch it a window appears but nothing is displayed in it. Few seconds after the program quits and my shot.png has the good size but is empty. The problem is the same with any other web page, even local one.

Re: [Mono-list] About the thumbnail creator
I think the issue is mozilla not getting enough time to render. I would try putting a Thread.Sleep (3000) or something as the first line of code in the NetStop handler. --Todd Benoit Caccinolo wrote: When I launch it a window appears but nothing is displayed in it.

The problem is surely a problem of time. But with a Thread.Sleep in the
MakeShot method the problem is not solved cause the sleep stops the
rendering too :)
My solution is too put a button to launch the MakeShot method. It is
less elegant but it works.

Re: [Mono-list] About the thumbnail creator
heh, the or something was important ;)
The proper way to do it, is to write a new event handle, and bind that
to NetStop. Inside that event handler, you set a Gtk.Timeout for 3
seconds later, and then in the Gtk.Function the Gtk.Timeout calls, you
take your sshot.
