Using IE within a Windows Forms application
Changed this blog posting into an article. It's just too long for a post, and might be handy to keep around...
Everytime I'm busy with something I think: hmmm, would be nice to share this.. but one way or the other the time just isn't there. I will try harder...
I'm working on a simple windows forms app to browse some of the hierarchies of SharePoint Portal Server 2003, and besides a tree control on the left side I needed a browser control at the right side to display some detail information in HTML. Of course you can add the Internet Explorer dll shdocvw.dll to the toolbox so a wrapper is generated... but there are some problems left like what values to pass for all those parameters and how do I handle events that are raised.
One of the .Net world famous programmers Lutz Roeder, developer of Reflector (http://www.aisto.com/roeder/dotnet) did write a class encapsulating the Internet Explorer Active-X control that is used in Reflector. Although he did not publish the source code (as far as I know), this file came on the web one way or the other. I found it at the following link:
The code follows below, together with some code how to use it....

And now some example code describing how to use it... I created a window with a tree control at the left, the Internet Explorer at the right and a splitter in the middle so the controls can be resized dynamically...

using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.Threading;
using Reflector.Library;
namespace SPS2Admin

public SPS2Admin()

InitializeComponent();
_htmlBrowser = new HtmlBrowser();
_htmlBrowser.Parent = this;
_htmlBrowser.Dock = DockStyle.Fill;
Splitter split = new Splitter();
split.Parent = this;
split.Dock = DockStyle.Left;
split.BackColor = SystemColors.Control;
spsTree = new TreeView();
spsTree.Parent = this;
spsTree.Dock = DockStyle.Left;
_htmlBrowser.Navigate("http://www.macaw.nl");
}
:
:
}
}
I did display only some relevant part of the code... this should do the job, no "design time" control, but hey.. who needs that!
Update:
I got a solution from Julien CHEYSSIAL to resolve the problem concerning controls like textbox,
combobox which were displayed with the old looking style while using the WebBrowser in a Windows Form application. You have to add this meta in the head section of your pages : <META HTTP-EQUIV="MSThemeCompatible" Content="Yes">. See http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnie60/html/whatsnewpublicpreview.asp and http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/commctls/userex/cookbook.asp for more info.

You are certainly going to love the WebBrowser control in VS.NET 2005! No more low-level plumbing - nice, clean managed class! [url=http://dev.csdn.net/javascript:__doPostBack(][/url]
