You can create a <code>CMenu</code> object dynamically like this:

<pre><code>CMenu *menu = new CMenu;
menu-&gt;CreatePopupMenu();
// Add items to the menu
menu-&gt;AppendMenu(MF_STRING, menuItemID, "Text");
...
</code></pre>

Then add this sub-menu to your main menu:

<pre><code>wnd-&gt;GetMenu()-&gt;AppendMenu(MF_POPUP, (UINT_PTR)menu-&gt;m_hMenu, "Menu Name");
</code></pre>

As for the message map, assuming all your menu item IDs are within a certain range, you can use <a href="http://msdn.microsoft.com/en-us/library/9ab3z9tb%28VS.80%29.aspx" rel="noreferrer"><code>ON_COMMAND_RANGE</code></a> to map the entire range to a single function. This function will receive the ID as a parameter, and within the function, you can perform different operations based on the ID.

Following example if you wish to dynamically add menu item &amp; also attach data to that menu item.

<pre><code> struct MyStruct
 {
 int abc;
 };
 CMenu MyMenu;
 MyMenu.CreatePopupMenu();

 CMenu MyMainMenu;
 VERIFY(MyMainMenu.LoadMenu(IDR_MAIN_MENU_ID));
 MyMainMenu.InsertMenu(0, MF_POPUP, (UINT_PTR)MyMenu.m_hMenu, _T("Main Menu"));

 const int iMenuAdds = 5;
 for (int i = 0; i &lt; iMenuAdds; ++i)
 {
 MyStruct myStruct;
 myStruct.abc = i+10001;

 CString MenuDesc;
 MenuDesc.Format(_T("MenuNo: %d"), i);
 MENUITEMINFO tmpItem;
 tmpItem.fMask = MIIM_STRING | MIIM_ID | MIIM_DATA;
 tmpItem.fType = MFT_STRING;
 tmpItem.fState = MFS_ENABLED;
 tmpItem.wID = i + 101; //See note 1. below.
 tmpItem.dwItemData = (ULONG_PTR)&amp;myStruct; //data set.
 tmpItem.dwTypeData = MenuDesc.GetBuffer(); //string description
 tmpItem.cch = MenuDesc.GetLength();
 tmpItem.cbSize = sizeof(tmpItem);
 MyMenu.InsertMenuItem(i, (LPMENUITEMINFO)&amp; tmpItem, FALSE);
 }
</code></pre>

To retrieve menu item &amp; associated data:

<pre><code>CMenu* pPopup = &amp;MyMenu; //or CMenu* pPopup = MyMainMenu.GetSubMenu(0); depending on parent.
ULONG_PTR lRetVal = pPopup-&gt;TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON | TPM_RETURNCMD, point.x, point.y, this, NULL);
//^^lRetVal should return same value as tmpItem.wID above.

MENUITEMINFO tmpItem;
tmpItem.cbSize = sizeof(MENUITEMINFO);
tmpItem.fMask = MIIM_STRING | MIIM_ID | MIIM_DATA;
tmpItem.fType = MFT_STRING;
TCHAR dwTypeData[256];
tmpItem.dwTypeData = dwTypeData;
tmpItem.cch = 256;
pPopup-&gt;GetMenuItemInfo(lRetVal, &amp;tmpItem, FALSE);
MyStruct *myStruct = (MyStruct*)tmpItem.dwItemData; //and now we have our data.
</code></pre>

<ol>
<li>Used as your #define &amp; can be used for ON_COMMAND_RANGE(idFirst, idLast, Function), so would still need to have some sort of defined range if you were planning on using ON_COMMAND_RANGE. Alternatively: <a href="https://stackoverflow.com/questions/19108015/use-command-range-for-dynamic-menu">use command range for dynamic menu</a> or create your own within the data set. Also need to make sure any ranges used do not conflict with any already #defined menu items on the same or parent menu.</li>
</ol>

Added above as I found this thread from googling due to an issue &amp; I was already using the accepted answers method for adding menu items.

I would like to add a menu item to my main menu and then populate it with items at run time. How would I do this? And besides adding items how would I have a message map entry for them since I do not know the id?

我想在我的主菜单中添加一个菜单项，然后在运行时用菜单项填充它。我该怎么做呢？除了添加条目之外，由于我不知道id，我如何为它们创建消息映射条目呢？
