Taskbar state change notification.

[Guest]

I am developing a Windows Forms application using VS.Net 2003 in C#. My
application is normally sized to cover the entire desktop when it is not
iconified. I would like to resize the application depending on whether the
Windows TaskBar is in the hidden or displayed state.

Is there a notification that my application can hook to when its state
changes?
Is there a system variable my app can query to get its state (hidden or
displayed)?
Is there a system variable my app can query to get the position and size of
the TaskBar?

Thanks,
Dave

Dave,

To get notified when the taskbar moves, try overriding
Control.PreProcessMessage() and look for the WM_SETTINGCHANGE message
and SPI_GETWORKAREA. See

and

I haven't tried it so I don't know that it actually works.

Some stuff on finding the position of the system tray:

Or, if writing your own system tray type of control, Arik P. has a nice
CodeProject article on this using .NET:

I know that's a assortment of links, but it should get you started.
Post back if you get it working!
