SearchDirectory

[C# Programming]

The Microsoft Windows search "textbox" on the top-right corner of the Window Explorer is not too efficient when searching for files. So, I thought I should write something that would provide an easily way of searching for files in your Windows directories.

There is a small application written to do a quick and smart search of files in a directory. It's still under development and your comments and contributions would be appreciated.

The "find" method should search within the ResultTextBox then select and highlight it.
