Hey Daniel,

Well, this is somewhat a simple solution.  It comes to the point of two possible
answers that you can follow, to make it work.  The first method, is to staticly
create the Menu Items under all of the Menus, then use setVisible() to hide, and
show thoes items that the User Selects.  That's Method one.

Method Two, is to store a list of Menu Items in a Sequence, which should look
something like this:

constant MenuArch = {
  {ID_FILE,"&New",ID_NEW},
  {ID_FILE,"E&xit",ID_EXIT},
  {ID_EDIT,"&Cut",ID_CUT},
  {ID_EDIT,"C&opy",ID_COPY},
  {ID_EDIT,"&Paste",ID_PASTE}
}

This way, you have your Basic Structure of where items will go, and drop
them in there fairly easy.  Then you can dynamically have a sequece list
of the actual item id's, so you can delete them.  You wouldn't need it
for anything else, cause you can simply use setHandler() to add the 
w32HClick event to the Menu Item, when you create the control.  Other then
that, it's fairly easy. Any Win32 Control can be created multiple times, with
the same definition, as long as you can get a Unique ID to identify it from
others.

BTW, there will be one more option you can use, which is to use SOOP to
handle it.  You can have a simple sequence in the main "Menu" class, which
holds all of the Menu's, and Sub-Menus, then create a "MenuItem" class, in
which to classified everything, and structure your routines as such.

It's pretty much how you will do it now, with Normal Euphoria, but offers a
more structured way of doing things, since you can Inherit from a parent
class, and have everything run the same exact way, only with your own
customizable Routines.  This will be one of the Win32lib Demos I will do for
SOOP 1.0

Hope this helps,
