Changing Window Attributes

When you register a window class or create a window, you get to specify window attributes, however once your window is running, you may wish to change the window's attributes to do something like removing the taskbar button for a window on minimizing (used in the 'Minimize to tray' feature of applications). This can be done using SetWindowLongPtr (SetWindowLong can be used too, but it will not work on 64-bit versions of Windows).

I've read some time back in an MSDN article that the window has to be hidden/disabled (I can't remember which... my guess would be hidden) before the attribute is changed. I'll try it and post the code for it sometime soon.
