CodezBank is just a small application that stores source code snippets organized in a hierarchical manner with basic search ability. You just copy and paste the code snippet into or from this application via the Clipboard. If you have a bag of coding tricks, then you want to keep them in this app.
Every time I work on some project, I always find myself digging through books and my old files to see how I did one or another piece of code. Although it works, it usually requires a lot of time. Sites like CodeProject keeps code always available, but if I am offline or on a remote location without the connectivity, then I have always wanted a small application that keeps the code snippets organized and handy.
