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.

If you're an IE user you may have noticed that when you hover on a medium to large sized image, a toolbar appears in the corner of the image. It's basically useless as it accomplishes nothing that can't be done with a right-click.
Luckily, Microsoft has included a way for webmasters to disable this function.

Similar to Perl's CGI::escapeHTML(), though (because we can!) this adds it as a method to all String objects.

This code was something I used to monitor the keys that where press while a user would be entering text into a text box in my application. I monitored and watch for the user to hit the "Enter" key and then perform some task. Handy code for chat applications.

Turns any string backwards. If you input "Test" it gives out "tseT". Hope it's useful.
The snippet shows how to use it.

The modus operandi for this is similar to that taken by PHP's implementation of such functions. It's comparitively memory-intensive, but is much faster than running a whole bunch of tests.
Basically, you set a mask -- an array of 256 null bytes -- and set those that correspond to characters you wish to trim. Then, rather than having to test if a character is in the set of characters to trim(O(n), or linear time on *ws), you just test once (O(1), or unit time) to see if the byte in question is set.
And of course, to trim(), you just wrap trim() around both ltrim() and rtrim().
One point of caution: these functions trim in place, so copy strings before trimming them. (Of course, if you usually want access to both pre- and post-trimmed strings, you could always make these malloc() a new string and return a pointer to it . . . )
