Creating a MenuHandle

Hi all,

I would like to set a checked mark to the menuitem that was selected by the user.
The CheckMenuItem seems to be the correct function,CheckMenuItem(HMENU hmenu, UINT
uIDCheckItem, UINT uCheck), but how do I create handle to a menu that is defined in the resources?
Or what else is needed to get the checked mark showing up?

Thanks for your help.

getmenu will return a pointer to a CMenu.
CMenu has a CheckMenuItem member function.

Also,
if the menu is not created yet you can use
LoadMenu, setmenucheck and then setmenu.

Hi,
Could you please help me with this code? It doesn't do anything... and I don't have a setmenucheck function in my help library...


HMENU hMenu;

hMenu = LoadMenu(hInstance, "IDC_F4MEM");

case IDM_START:
{
CheckMenuItem(hMenu,IDM_START,MF_CHECKED);
}
break;




When I select Start from the menu, nothing happens regarding the
checked-mark.

Thank you for your help.

First, is your application win32 only or mfc.
this will tell me if you have access to the
CMenu class. if not, no big deal. i will do
up a example in win32.

It's Win32 only. No MFC and no CMENU.

Thanks!

The code could have been much shorter. but i thought maybe you would want to see the whole
thing. if you have any questions on the code
let me know.
