Creating dynamic menu items

**abachler** · 10-08-2008

Im learning to make dynamic menues for an application I'm writing, btu this code from petzold doesnt create the proper result. Perhaps I'm missing something.

Code:

hMenu = CreateMenu();
hMenuPopup = CreateMenu();
pOption = (UINT_PTR)&Option;
Option = 40001;
AppendMenu(hMenuPopup , MF_STRING , 40001 , "E&xit");
Option = (UINT)hMenuPopup;
AppendMenu(hMenu , MF_POPUP , pOption , "&File");
SetMenu(hwnd , hMenu);

all it creates is the File menu, but with no popup item in it.

hMenuPopup needs to be a handle to CreatePopupMenu(). Otherwise the way you have it now it creates two menus, one File and one Exit, and you are only showing the File one.

Code:

HMENU hMenu = CreateMenu();
HMENU hSubMenu = CreatePopupMenu();

AppendMenu(hMenu, MF_STRING | MF_POPUP, (UINT)hSubMenu, "&File");

AppendMenu(hSubMenu, MF_STRING, FILE_EXIT, "E&xit       Alt+F4");

Thanks, after a bit of tweaking that worked fine.
