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 browser) { …

Using Bootstrap Tooltip to show Parsley validation errors

I'm currently working on a web application using a variety of different frameworks, such as Backbone for the back-end, Bootstrap for the front-end and Parsley for client side form validation. Parsley is a really powerful validation toolkit, but it takes some tweaking to make it blend with the Bootstrap front-end. Fortunately this is a one time fix, which can be re-used all over our project.

Since there will be some custom options in our Parsley object, we can't use the default parsley-validate attribute on the form. Instead we have to initialize the validation with the jQuery syntax:

$('#my-form').parsley(parsleyOptions);
The options are were the magic happens, and in our case we have a global options object that our forms use to get the same experience all over the application. Here's what it looks like:

var parsleyOptions = { // Sets success and error class to Bootstrap class names successClass: 'has-success', errorClass: 'has-error', // Bo…

jQuery file upload with Bootstrap progress bar

Performing an asynchronous file upload from the browser is a common problem with almost as many solutions as there are developers. The following solution is the best fit for my needs, and also works well with most popular browsers. Backwards compatibility is not an issue in this case which is great, because I can use the new technologies as they are supposed to be used.

Everything is put together in JSFiddle for a working example. I will continue to explain the parts below...

First, the input field needs to be styled as a button. The form tag is only present for us to be able to reset the file input field later on.

<form> <span class="fileUpload btn btn-default"> <span class="glyphicon glyphicon-upload"></span> Upload file <input type="file" id="uploadFile" /> </span> </form>
.fileUpload { position: relative; overflow: hidden; } .fileUpload input { position: absolute; …
