Below is a bit of code which sets up drag and drop in a treeview. This is handy for if you have a list of items that can be sorted by the user.

Here is a bit of code to demonstrate how to do this. First create a new Windows executable project. Drop a TreeView component on the form, and let's name it 'myTree' for this demonstration. Go ahead and populate it with some dummy data; enough data to see the dragging and dropping in action. You will need a variable global to the form's scope.

private TreeNode sourceNode;

This is used to track the item we are dragging in our TreeView. Then define the event handlers listed below.

This snippet generates a secure hash string using VB.NET

Returns a string collection of IP addresses for a passed in domain name.

This function returns a stack trace for an exception with all inner exceptions include unless the count of inner exceptions goes over 50. A stack overflow can occur if there is no upper limit for inner exceptions to read from.

Makes use of stringbuilder to build return string in order to yield higher performance.

This function provides the reverse of a string. It is constructed using string builder because strings in .NET are immutable, while stringbuilders are not. Therefore large strings could be slow to reverse if a regular string was used for the working value that is returned.
