This example creates a menu window from the menu template (idMenuId) located in "RES.DLL" and returns a menu handle which is used by WinPopupMenu.

#define INCL_WINWINDOWMGR   /* Window Manager Functions */
#define INCL_WINMENUS       /* Window Menu Functions    */
#include <os2.h>

HWND    hwndMenu;           /* Menu window              */
HWND    hwndOwner;          /* Owner window             */
HMODULE hmodDLL;            /* resource handle          */
ULONG   idMenuid;           /* Resource menu id         */
BOOL  fSuccess;             /* Success indicator        */
HWND    hwndParent;         /* Parent window            */
ULONG   flOptions;          /* Pop-up menu options      */

if (DosQueryModuleHandle("RES.DLL",&hmodDLL))
   hwndMenu = WinLoadMenu(hwndOwner, hmodDLL, idMenuid);

flOptions = PU_MOUSEBUTTON1DOWN |
            PU_KEYBOARD |
            PU_MOUSEBUTTON1;
fSuccess =  WinPopupMenu(hwndParent,
                         hwndOwner,
                         hwndMenu,
                         0, 50, 0,
                         flOptions);
