This snip opens any kind of document (e.g. .PDF, .DOC, .C, .HTM, etc.) using the default application associated with it. This relies on starting a new process with the .UseShellExecute property set to true.
The main overloaded function OpenDoc(filename) will open any associated document using the default OPEN verb. If you are trying to edit a file, for example, a command file, then you need should call OpenDoc with the "EDIT" verb. Some associations also a "PRINT" verb.
Since the return result is a System.Diagnostics.Process object, you can also monitor or kill the process.
Example:
OpenDoc("C:\\SomeDocumentation.pdf");
OpenDoc("C:\\AWebPage.htm", "EDIT");
OpenDoc("C:\\Test.txt", "PRINT");
System.Diagnostics.Process doc = OpenDoc("C:\\WebPage.htm");

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.

I was coding a project that used arrays when the lack of a standard foreach in C/C++ got to me. So, I coded this little function to help me. It applies a function that returns int to each element of the array.
