Simple loop through datatable

This is a function that receives a dataTable and return it in a pivoted way.

Converts a string representation of a number with any base(binary, octal, decimal, hexadecimal, up to base 36) to a long int.

Convert an ebcdic buffer to an ascii buffer.

Set the read-only attribute of a file to true or false.

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.

Write a set of bytes into a so-called binary file. The point is that we use BinaryWriter here and we have a byte array as input.

A function to determine if the input filename is valid on Win32 platforms (that is, it does not include invalid characters, such as :\?...)

Write a set of bytes into a 'so-called' binary file. The point is that we use BinaryWriter here and we have a byte array as input.

This snippet effectively reads an XML document using XPathDocument (read-only) instead of using the DOM. This snippet returns the full element values in between elements. For example:

root element
code element
This is a test.
/code element
/root element

GetXmlString("/root/code"); //returns 'This is a test.'
