WebBrowser: setting manually Document.Body.InnerHtml

Hello,

I'm trying to implement a help in my test application. The home page of the help is defined in the configuration settings.

When no setting has been found, I would like to display "No help available". My problem is that WebBrowser.Document is readonly and by default Body is Nothing... How can I do that???

Thank's a lot
Serge

Perhaps the browser control doesn't have its Document property set, in which case it will throw a NullReferenceException. You can use the DocumentText property to build the HTML manually. This is easier than working the DOM object model.

StringBuilder builder = new StringBuilder();

builder.Append("<html>");

builder.Append("<title>Help not installed.</title>");

builder.Append("<body>");

builder.Append("There is no help available.");

builder.Append("</body>");

builder.Append("</html>");

webBrowser1.DocumentText = builder.ToString();

HtmlDocument htmlDoc = webBrowser1.Document;

Another, better, option is to distribute a "No help available" html page with your application, and load this when there is no help setting:

webBrowser1.DocumentStream = File.Open(@"..\..\HelpNotInstalled.htm", FileMode.Open, FileAccess.Read);
