Windows API: Removing the System menu
2003-03-28 -- Vernon Jay Godwin

Newsgroups: comp.lang.clarion


Hello,

Disabling the close button isn't too hard.  Will require a bit of work tho:

First...define these in the global map...

      GetSystemMenu(unsigned, signed),unsigned,PASCAL
      RemoveMenu(unsigned, signed, signed),signed,PASCAL
      DrawMenuBar(unsigned),signed,PASCAL

Now, on the window you want to disable the close button on...do the
following:

Add Following Data:

   hMenu         unsigned
   nRemove     signed
   nDraw         signed

- "After Opening Window" Embed

    hMenu   = GetSystemMenu(Window{Prop:Handle}, 0)
    nRemove = RemoveMenu(hMenu, 0F060h, 01000h)
    nDraw   = DrawMenuBar(Window{Prop:Handle})

Welp, that was quick :)

Hope that helps,
