Code Example

The following code example demonstrates how to display a shortcut menu based on an existing resource.

Note:
To make the following code example easier to read, security checking and error handling are not included. This code example should not be used in a release configuration unless it has been modified to include them.
Copy Code 
// Global for handle to menu resource.
HMENU g_hMainMenu;

BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{
   ...
	// Load the menu resource to use later.
	g_hMainMenu = LoadMenu(g_hInst, MAKEINTRESOURCE(IDM_MENU));
	...
}
LRESULT CALLBACK WndProc(HWND hWnd, UINT message, 
						 WPARAM wParam, LPARAM lParam)
{
	switch (message) 
	{
		...
		case :
		{
			SHRGINFO  shrg;
			HMENU	hmenu;

			shrg.cbSize = sizeof(shrg);
			shrg.hwndClient = hWnd;
			shrg.ptDown.x = LOWORD(lParam);
			shrg.ptDown.y = HIWORD(lParam);
			shrg.dwFlags = SHRG_RETURNCMD ;

			if ((&shrg) == GN_CONTEXTMENU) 
			{
				hmenu = GetSubMenu(g_hMainMenu, 0);
				TrackPopupMenuEx(hmenu, TPM_LEFTALIGN,
LOWORD(lParam), 
								 HIWORD(lParam), hWnd, NULL);
		}
			break;
	}
}
	return 0;
}
