Environment: VC6 SP4, W2K SP2
In the process of creating my own shell for Windows I found that having all of the individual elements snap to the edge of the screen very useful. To make this process much easier I put together a small class that provides drop in window snapping. It uses a MFC like class so modifying it to use MFC should be easy. NOTE: For dialog windows use the CSnapDlg instead.
- Snaps to the edge of the desktop
- Adjusts to screen resolution changes
How it Works

It is quite simple to use. Here is how to use it.
// register class
// Perform application initialization:
