Hi!

Look at the Forms properties for BorderIcons
to disable the 'X' button set the biSystemMenu to false.

As far as i know you can't remove it entirely, however you can disable it.

Assuming close is the last menuitem in the systemmenu this is how i do it.. =)

Procedure DisableClose(FormHandle: THandle);
Var
  Menu: hMenu;
Begin
  Menu := GetSystemMenu(FormHandle, False);
  If Menu <> 0 Then Begin
    EnableMenuItem(Menu, GetMenuItemCount(Menu)-1, MF_BYPOSITION OR MF_GRAYED)
    DrawMenuBar(Menu)
  End;
End;

try this out:

var mnu:Hmenu;
begin
 mnu:=GetSystemMenu(self.handle,false);
 ModifyMenu(Mnu,SC_CLOSE,MF_BYCOMMAND,SC_CLOSE,nil);
 DrawMenuBar(self.handle);
end;


Good luck!!

Yes, you are right Raidos.
I didn't think to the end.
So, Asi! You should give the points to Raidos.
That solution is very good.
And yes Raidos pretty much beat us to it! ;)

Actually i think a combination of mine and drdelphis solution would be best..=)

Procedure DisableClose(FormHandle: THandle);
Var
  Menu : hMenu;
begin
  Menu := GetSystemMenu(FormHandle, false);
  If Menu <> 0 Then Begin
    EnableMenuItem(Menu, SC_CLOSE, MF_BYCommand Or MF_Grayed);
    DrawMenuBar(FormHandle);
  End;
end;

And I learned something new.. =)

"Actually i think a combination of mine and drdelphis solution would be best.."


-surely you don't propose that asi split those 25 points, do you? It's okay for the 24, but that last 25th point could really get mangled! <g>


"And I learned something new"


-As did I... cool , huh?

haha...no i don't propose anything.. =)

and i don't really care much about the points...he/she/it can award it to you DrDelphi, i won't have any sleepless nights over it.. =)

The only reason i hang around E-E is to learn new stuff, and no points in the world would teach me all that i've learned on E-E these past 2 years or something..
