Copy a file to a new location, optionally marking the file as a temporary file (to be deleted on application exit).

Note there are issues for temporary files - not all the parent directories that might be created are guaranteed to be deleted - only the immediate parent directory will be deleted on exit if created. Other higher-level directories will not be deleted, even if the file is marked as temporary.

Class method to read a binary file and copy it to a byte array.

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.

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

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

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.

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.

Vendor Application with Style Override via URL

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!

This function tries to locate a file in a give folder (either single level, or in any sub folder). Returns the relative file and path, or FALSE if not found. Skips over "." and "..".

The fFile variable determines whether you're
looking for a File (True) or Folder(False)
The strName variable holds the fully qualified
path you're looking For
