Tips & Tricks:

To add a submenu use MF_STRING in conjunction with MF_POPUP passing to the [uIDNewItem] parameter the handle to the submenu parent item as illustrated in the Sample Code section.

Sample Code:

IntPtr hMenu = CreatePopupMenu();

uint flags = MF_STRING;

AppendMenu(hMenu, flags, 1001, "Simple Menu Item");

IntPtr subMenuParentItem = CreatePopupMenu();

flags |= MF_POPUP;

AppendMenu(hMenu, flags, (uint) subMenuParentItem, "Pop-up Parent Item");

AppendMenu(subMenuParentItem, MF_STRING, 1010, "Submenu Simple Item");
