Embedding Mozilla in c#: Browser is not in a valid state

[EricBlair]

Hi,

New to mozilla embedding. In .Net C# I have an app that loads the
browser when I place it in a new form and it runs.

But I want to load the browser as a Browser (in the native browser
window) when I try to do this:

AxMozillaBrowser BrowserApp=new AxMozillaBrowser();
BrowserApp.Navigate("http://www.somesite.com");

I get this error:
Exception of type 'System.Windows.Forms.AxHost
+InvalidActiveXStateException' was thrown.

If I try this:
MozillaBrowser BrowserApp=new MozillaBrowser();
BrowserApp.Navigate("http://www.somesite.com", ref o, ref o, ref o,
ref o);

I get this error:
Browser is not in a valid state

System.Runtime.InteropServices.COMException was unhandled
Message="Browser is not in a valid state"
Source="Mozilla.Browser.1"
ErrorCode=-2147418113

I must be missing some initialization call, I don't what it is.

Anyone here done this successfully and have any tips?

Thanks!

Have you tried command line? Something like this...

Dim p As Process = Process.Start("firefox.exe", """www.webdeveloper.com""")
System.Threading.Thread.Sleep(5000)
p.Refresh()
If Not p.HasExited Then
p.CloseMainWindow()
p.Close()
End If

Yup. I know I can do that. But that's a different issue. I want to run the mozilla embed.
