Close box in Windows XP

[Sarah Reichelt]

Does anyone know how I can get rid of the close box in a stack window 
with Windows XP? In Mac OS X, I can set the decorations to 
"title,menu,maximize,minimize" which gives me exactly what I want with 
a close button visible but disabled. In Windows XP, no combination of 
settings seems to disable or hide the close box except if you remove 
"menu" from the decorations, which I don't want to do since it removes 
everything.

Does any Windows expert out there know how I can hide the close box? I 
don't want to just trap the message and refuse to close the window as 
that would cause confusion, but I really don't want the users to be 
able to close a particular window unless they are quitting the entire 
application.

TIA,
Sarah
