This does not happen to me. Other people have also reported this but I can't 
seem to find the reason. Maybe it is a webkit bug. I leave this issue open 
until the problem is gone when I upgrade to a newer WebKit build

OK.  Is it a 64/32 bit type bug I wonder?

I tried example.exe on Windows XP Pro 32-bit.  I got English.ini not found 
exception.  Not sure about that one.   I copied the C:\openwebkitsharp 
directory from the Windows 7 machine.

I received this kind of bug reports also from 32-Bit machines but only for 
HTML5 test. Not for the GoBack() method. For the Example to run there must be 
all files from the Core folder inside the same folder as teh exe's and the 
files from the References folder. The English.ini file is required by the 
LanguageLoader class and should be in \LanguageLoader.resources\English.ini

Getting a COM interop error.  Nonetheless hopefully a newer webkit will handle 
this.  I would prefer webkit over IE.  And you seem to have the best 
implementation for winforms.  

When it works.  It works well.  I will do some more tests.  It works ok with my 
PHP reportmaker generated sites.  Just occassionally right click back and it 
blows with AccessViolationException.

I am several months before I need the web browser feature in our Law 
Enforcement app.  I will help in any way I can to improve this library.

BTW.  Don't worry about my XP issue with example.exe.  I will try some more in 
my app. in Windows 7 Pro x64.  When do you think you be etting a newer webkit?

The build we are using is almost the latest It was built about a week ago and I 
have been looking to the webkit's repository for commits but nothing had to do 
with this kind of issues. The main problem is that I don't experience this 
problem, so even if I upgrade to the latest build I won't be sure if the 
problem is fixed.

I will try as soon as you release a new one.  I will also duplicate on my XP VM 
as well.  The only other issue is I get javascript errors on a couple of pages 
when I do a print dialog command.  I tried disabling the javascript feature and 
it still does it.  This is a minor issue I will need to dig to fix.  

I will do what I can to help you corner this problem.

Thanks! I appreciate that! As for JavaScript printing, is is handled inside 
uiDelegate.printFrame(WebView WebView, IWebFrame frame). If you remove the code 
from there JS printing is not allowed. You can edit this method in your own 
OpenWebKitSharp build inside the WebUIDelegate.cs file.

I am updating in a newer WebKit build right now but firstly I would like to 
bring this issue again to top and ask you: Do you use a user agent?

Original comment by tsumalis96@gmail.com on 5 Feb 2012 at 7:39

GoogleCodeExporter commented 9 years ago 
No user-agent.  All this is for is a reports from an intranet web site.  

Basically I dock the control into the window.  Do 
webkitcontrolname.Navigate("url string")
I'll try the new version as soon as it is available.

OK Thanks for the info! The latest WebKit seems a bit unresponsive but I think 
I will make it work.

Problem is resolved.  It requires Quicktime.  Also QTCF.dll needs copied into 
folder w/ the .exe.  

Basically, open webkit sharp does not gracefully deal with the lack QT.  No big 
deal.  I would not be using anything invoking QT.

Side issue.  I get an Javascript errors when I invoke 
WebKitBrowser1.ShowPrintDialog(). 

I have attached a PNG of the window.  I get similar error on any web or 
intranet page that contains Javascript.

I will fix the above issue with JS. Thanks for the solution with Quick Time! 
That's why I was not having problems with the html5test page...

Updated r119.  I am still getting the JS printing issue.  It may not have been 
intended on being resolved in r119.

But an FYI nonetheless.

I ran into this same issue at html5test.com and solved it by blocking 
*.doubleclick.net.

I'll remember the QuickTime solution though.
