I love Mark Russinovich's
ZoomIt tool, which
one of the best zoom utilities for Windows.
I wanted to see if I could use Vista's DWM API to build a similar utility, with the addition of live window updates, so I put together this small program (372 lines).
The keyboard shortcut to activate is Ctrl+~
Use the mouse wheel of up/down arrows to zoom in/out.
Some feedback would be apreciated.
Edit: Source Code added to zip file.
