Active Directory Topology Diagrammer

I sometimes get very positively surprised by Microsoft. In the work of cleaning and structuring an Active Directory environment we wanted to produce a graphical overview of our current forest. It did not take long before I found Active Directory Topology Diagrammer, which is an absolute perfect tool for this purpose. And it is free!

Active Directory Topology Diagrammer gets the entire AD structure according to the parameters you supply and draws the structure in a Visio document. It does however require Visio 2003 or later installed to be able to do this export.

Binding a HTML-formatted string to a WPF WebBrowser control

Sometimes there is a need to display a HTML formatted string in a WPF application. There are a couple of ways to do this, but the most stright forward is to use a WebBrowser control and the NavigateToString method. This approach has one big flaw, you cannot use binding to a string out of the box, but I found a great solution through Stack Overflow which adds a bindable property to the WebBrowser control using NavigateToString . The following class is all that is needed to add that behavior. A new depencency property named Html is introduced to the WebBrowser and the proper change action is performed in the OnHtmlChanged method. public class BrowserBehavior { public static readonly DependencyProperty HtmlProperty = DependencyProperty.RegisterAttached( "Html", typeof(string), typeof(BrowserBehavior), new FrameworkPropertyMetadata(OnHtmlChanged)); [AttachedPropertyBrowsableForType(typeof(WebBrowser))] public static string GetHtml(WebBrowser bro

Binding Enum with DescriptionAttribute in WPF

Binding an enumeration to a ComboBox can be done in several ways. In most cases you don't want to display the value itself, but a more user friendly description. One common approach is to use the DescriptionAttribute on the Enum values to supply a description for each value. This is all possible in a very MVVM friendly way. First step is to add the DescriptionAttribute to the values of the enumeration. public enum MyValues { [Description("First value")] First, [Description("Second value")] Second } To retrieve the description from the enum we use a simple extension method. This method returns the value of the DescriptionAttribute if it exists, otherwise the string representation of the enum value is returned. public static string GetDescription(this Enum value) { var fieldInfo = value.GetType().GetField(value.ToString()); var attribute = fieldInfo.GetCustomAttributes(typeof(DescriptionAttribute), false).FirstOrDefault() as

Bindable RichTextBox with HTML conversion in WPF

In WPF , the RichTextBox control is not really like other controls. Due to its flexible nature, there is no built in way of binding a property to the content. In this case, I wanted a simple RichTextBox control with a binding to an HTML formatted string to be able to use the built-in formatting features of the RichTextBox and allow users to create simple HTML formatted content. First, doing the conversion on-the-fly proved to have major performance issues, so I ended up binding the content to a XAML string. The XAML to HTML conversion can be performed at any time. I created a UserControl with a bindable Text-property. The view contains a RichTextBox control. <RichTextBox x:Name="richTextBox" TextChanged="OnRichTextBoxChanged"> The source code for the user control contains the Text property and the methods to handle the binding. public static readonly DependencyProperty TextProperty = DependencyProperty.Register( "Text", typeof(st
