Webbrowser edit works in XP but not in Windows 7 ??

Hi Guys,

Another one of those Win 7 breaking changes, I guess, like the Print dialog thing and the progress bar issue...

I have an HTML text box based on a web browser control which I use in an email dialog amongst other things, and it works perfectly under XP regardless of how it is used.  However, under Windows 7 it does not accept the cursor and ignores any keypresses.

Can anyone suggest a cause and resolution for this?

This is not because of Windows 7, Its because of IE9 on some systems, if you uninstall IE9 on win7 then you'll see your solution working. For reference, see

Hi guramrit:

Thank you for your response - it is certainly useful to know what is causing the issue.  However, even if their system permits asking all my customers to uninstall IE9 is not an option....

Can you suggest how to get around the problem without uninstalling?

Hi guramrit:

Your input enabled me to find the right search terms and google other solutions.

For the benefit of others, the actual solution is to reset the document design mode flag in the DocumentCompleted handler:

        private void WebBrowserBodyDocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
            if (webBrowserBody.Document != null)
                var doc = webBrowserBody.Document.DomDocument as IHTMLDocument2;
                if (doc != null)
                    doc.designMode = @"On";

Open in new window

Thanks for the pointer - the key thing was finding the right search terms to use in Google!
