Re: [Wrapper-user] Preventing Close on UI part of service

[Leif M. <le...@ta...>]

Bill,
    The Window in the task bar is being displayed by the Java process so I
don't think there is anything that I can do about it from the Wrapper.

    As a workaround though, have you tried playing around with adding a
WindowListener to your frame.  If you simply do nothing in the
windowClosing method you should be able to prevent the user from
closing the window.  As far as iconifying and maximizing the window.
It doesn't look like you can prevent the user from doing so, but there
are events that are fired that you can react to.   If they iconify the 
window
simply restore it.  Same with maximizing the window.   For the position,
you may need to have a thread which checks the position of the window
every 100ms or so and resets the position if it has changed.

    All a bit hackish, but it should work for you.  The only other idea 
would
be to have a native DLL lookup the window handle using its exact name
and then modify its attributes from the Windows API.  That sounds more
messy though...

Post back with the results of whatever you end up doing.

Cheers,
Leif
