I like to have these two methods in my toolbelt, even though it's syntactic sugar, I think it aids clarity.

create a random string of 16 chars

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

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 :\?...)

This is a PHP and JavaScript Image gallery that I created. There are 2 uses for this.
1.) You can save it as index.php and place in a folder containing images and it will display the images in that folder.
Example:
place index.php in images/folder
http://yoursite.com/images/folder/
This will display all images in that folder

2.) Pass in the path to the folder to display in the url
Example:
Save as imagegallery.php
http://yoursite.com/imagegallery.php?path=images/folde

I wrote this simple snippet to allow one of our vendors to accept a style override so that their application would morph into something more closely resembling our own portal application. Please see screenshots for clarification.
