QuoteControl Spy is a tool that helps developers understand common controls: how to apply styles to them, and how they respond to messages and notifications. Using Control Spy, you can immediately see how different styles affect the behavior and appearance of each control, and also how you can change the state of each control by sending messages.
Not sure if you all have this, but it is interesting:

sounds like fun - i think they also have a WinSpy someplace for watching windows in general
Nice tool.
WinSpy is not a Microsoft tool, it is available here (http://catch22.net/software/winspy). It is one of those esssential tools if you're going to do GUI programming, I use it a lot.
Well, "Control Spy" (v.2) - a well-known utility from MS :)
