XP Library: Registry, Files, Folders, Drives, Mouse and more! [Update 2]

[Ellis Dee]

Attached is the set of classes I use to interact with XP from VB6. The various functions adhere to Microsoft's "Designed for XP" logo program, which means that they should transition well to Vista.

The library is five classes in total; one main class that holds an instance of the four dependent classes, giving you a simple, unified entrypoint for all your OS needs.

Some key features:

• File/Folder Copy, Delete, Rename, and Move using SHFileOperation, which allows for both a progress meter (for long operations) and the recycle bin.
• Retrieve the size of a file, even if it's larger than 2 gig
• Retrieve the paths to special folders (eg: My Documents)
• Manipulate the Registry; read/write keys and values at any location
• Use common dialogs (eg: Open File) with API; no dependencies needed
• Control the mouse position and cursor, including the ability to hide it
• Enumerate logical drives and retrieve a drive's Serial #

There are many more useful functions included in the library. In addition to the five classes, the zip includes an extensive ReadMe.txt describing how to use each function. This ReadMe is reproduced in the next six posts.

You are free to use this code in any way you see fit.

Note: If anyone has a better way to do any of the functions, I encourage you to post them so I can update the library.
