Hello Thomas,

I tested out your provided code (thank you), and found that when I run this code I also receive an exception (though not a null reference).

I received the "null reference" until I built the project (using developer edition), however after "building the solution" the null reference went away. I was instead left with an "Inner Exception" for the line item that creates the invisible window.

The window is created, but no return is made on the creation, and the window cannot be manipulated further (other than to directly "kill" firefox). I have created bug 99948 to document and track this issue. I apologize that I do not have an ETA for this issue to be resolved. At this time I do not have a valid work-around to enable something similar either.

If you have any questions on this bug, please feel free to ask them.

Best wishes,

Hi Thomas Temme,

Our developers have finished reviewing the provided issue (BugID 99948). I regret to inform you that this specific issue has been determined to be functioning as intended, and that we will not be adding in support for the requested feature (to be able to appropriately handle invisible windows). The work-around I can suggest is to not use these types of windows.

I apologize for any frustration this data causes. Please feel free to let us know if you have any questions regarding this information.

All the best,

Hello there,

Meanwhile I've tried to use invisible Mode within other browsers with the newest Release (Q1/2011).
The issue in Firefox (Meanwhile Firefox 4) is still the same. The same issue occurs within Internet Explorer 7. Within the two Gecko Browsers (Chrome 11 and Safari 5) it works, but the browser keeps visible.

Example code:

Settings mySettings = new Settings(BrowserType.Chrome, @"C:\browserlog\");

Manager myManager = new Manager(mySettings);

myManager.Start();

myManager.LaunchNewBrowser(BrowserType.Chrome,true,ProcessWindowStyle.Hidden);

myManager.ActiveBrowser.NavigateTo("http://www.forwiss.uni-passau.de/~berberic/TeX/Rechnung/index.html");

myManager.ActiveBrowser.Close();

myManager.Dispose();

It would be great, if you could help me to get Invisible mode running succesful in any browser.

Many thanks,
Thomas
