The framework calls this member function when the user releases the right mouse button while the cursor is on a menu item.
The index position of the menu item when the right mouse button was released.
Pointer to the CMenu object that contains the menu item.
This method receives the WM_MENURBUTTONUP notification, which is described in the Windows SDK. The WM_MENURBUTTONUP message enables an application to provide a context-sensitive menu for the menu item specified in the message.
This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
This method is supported in Windows Vista and later.
Additional requirements for this method are described in Build Requirements for Windows Vista Common Controls.
