Adding dark mode to dynamically added sub-menus

Question

I have a CMFCMenuButton on my dialog which is set to the DarkMode_Explorer theme.

Therefore, when the dropdown menu part is display it is correctly showing with dark backgrounds.

The only caveat is that there is one instance where I load another menu resource and append it to my buttons' menu.

Code snippets:

• I load the menu that I want to dynamically add like this:

CMenu menuManageSpeakers;
menuManageSpeakers.LoadMenu(IDR_MENU_POPUP_MANAGE);

• I populate that menu's submenus dynamically (they show fine in dark mode). Then, I insert the menu to my menu button menu:

const CMenu* pSubMenu = menuManageSpeakers.GetSubMenu(0);
if (pSubMenu)
{
	pMnuPopup->InsertMenu(-1,
		MF_BYPOSITION | MF_POPUP,
		reinterpret_cast<UINT_PTR>(pSubMenu->GetSafeHmenu()), subMenuText);
}

Here you can see the problem:

It is odd that the sub-menus (level 3) are dark. But not this middle menu.

Hi,

I am able to reproduce the problem.

Declaring CMenu menuManageSpeakers as a class member or in the heap area work for me.

CMenu* menuManageSpeakers=new CMenu();
