Hi -

I'm trying out EO.Webbrowser as an up-to-date alternative to the MS component, but am having trouble getting started.

Following the Help instructions I added EO WebControl and WebView to the Toolbox with no trouble. I placed the WebControl on my form and the WebView appeared. I noted that EO.Webbrowser.Winform was automatically added to the References.

I set webView1.Url to "www.google.com" and tried a compile.

I got the error: "The type or namespace name 'WebBrowser' does not exist in the namespace 'EO'". Should I have added a 'using' assembly reference?

Any help would be gratefully received.

Many thanks. I added the extra references and it then compiled. It is BTW a Windows Forms app.

But when I ran it, it crashed in Main() at the call: Application.Run(new Form1()); with the error: "Exception has been thrown by the target of an invocation."

Can you tell me what I've omitted?

Many thanks.

Tony

The inner exception is: The InnerException is "Child process exited unexpectedly"

Does that help? I can zip and sent the project if not.

Still no joy....

The link suggested it might be my antivirus (AVG Free edition) so I disabled that, but it still crashed.

I added the suggested line:
EO.Base.Runtime.EnableEOWP = true;
to the Main() program but still got failure. However, the exception is now "System.Reflection.TargetInvocationException was unhandled" instead of "Child process exited".

I ran the TabbedBrowser.exe sample. I saw a tabbed dialog, and got a pop-up message "a licence is needed for EO.Wpf product". Shortly after that the dialog closed without showing anything interesting.

I'm getting desperate now. Any further suggestions?

Regards
Tony

I'm running Windows Home 10.0.18363 which I believe is the latest version.

I downloaded the EO material last Thursday.

Hi,

Visual Studio's version does not matter. This has to have to do with your AntiVirus application. As a temporary test, can you try to completely uninstall your AntiVirus application and see if it works?

Thanks!

I am not sure what else we can tell you then. There is something on your system that is interfering. We have a fresh Windows 10.18363.418 and it works fine. You may want to try on it on a different system and see if it works for you.

Sorry, I meant 37 kb!

Yes, but (see above) TabbedBrowser complained I didn't have a licence for EO.wpf. Should it still have run?

I just sent TabbedBrowser.exe to a friend with W10 and it doesn't work on his machine either.
Still, with this level of support it's better that I find some other way to solve the problem.
