How do I open default browser in fullscreen mode from a C# desktop application?

Question

Hi & thanks for looking!

How do I open default browser in fullscreen mode from a C# desktop application? I have seen similar questions on SO:

. . .BUT nothing addresses opening a local HTML file (C: drive) in a FULLSCREEN browser window from C#.

I can open the window using this:

Process.Start("http://google.com");

But how do I make it default to fullscreen? Is there a way to simulate the F11 key press, or even something more direct?

EDIT: Ideally, I will not need to have a form open. I don't want to confuse the issue, but I am experimenting with the Kinect Speech Recognition engine and will have a program running in the system tray, always listening. I already have it to a point that I can say a command and it will. . .

//do stuff

. . .and in this case, I just want it to open the default browser in fullscreen mode.

So, I don't have to be able to toggle back and forth between fullscreen and regular screen, just launch in fullscreen. I was thinking that a simulation of the F11 press would be the answer, but it sounds like I need a form open for this??

Thanks!

Matt

There is no standard mechanism for this, every browser implement their "maximized with no frame" mode differently. ProcessStartInfo.WindowStyle is all you got. — Hans Passant, Dec 27 '11 at 20:10
F11 appears to work for Chrome, Firefox and IE; while there's no clear standard this seems to get ~90% of popular browsers out there. — Jeremy McGee, Dec 27 '11 at 20:17

For that you would need to use sendkeys

Looking at the list you need something like:

ActiveForm.SendKeys("{F11}");

Hope that solves your issue.

SendKeys requires a form handle and I'm guessing the default browser won't necessarily be a subform of his application. – M.Babcock Dec 27 '11 at 20:11
@M.Babcock for me, I find sendkeys does it for any activeform, for instance, you can use send keys to spam notepad after creating that process – H Bellamy Dec 27 '11 at 20:12

wouldn't the SendKeys need to be

ActiveForm.SendKeys.Send("{F11}");

instead of

ActiveForm.SendKeys("{F11}");
