Is this file the same as that file? The files may or may not be binary. We could compare the modify dates, or the sizes. But, those are not very accurate to know if a file has really changed.
Introducing MD5 Checksum. We can feed the files into Digest::MD5 in binary mode.
This is a great way to do Incremental Backups.
This is also an easy way to verify checksums when downloading files from the internet which list their MD5 Checksums.
You'll need the Digest::MD5 Perl Module.

This snippet allows an aspx page (c#) to accept URL parameters to allow styles or script to be dynamically appended to the rendered page.
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.

This little number will allow the contents of other pages to be included or embedded into the rendered HTML of an aspx page. Using the WebClient class from the .NET framework, you can conditionally load pages, even manipulate the HTML before it is rendered and in this example, fill in forms and execute javascript actions.
The following example shows how to auto-login to an Exchange Server - this was something requested for inclusion into our portal, but I left out the logic that pulls/decrypts the real password - for obvious reasons.
Enjoy!

If anyone has tried using the .NET Graphics API, they know that replacing pixel colors takes a long time to complete. I did some research and found a good source. This code will adjust the color to greyscale by Binary.
