The framework calls this member function when the user double-clicks the right mouse button.
Only windows that have the CS_DBLCLKS WNDCLASS style can receive OnRButtonDblClk calls. This is the default for windows within the Microsoft Foundation Class Library. Windows calls OnRButtonDblClk when the user presses, releases, and then again presses the right mouse button within the system's double-click time limit. Double-clicking the right mouse button actually generates four events: WM_RBUTTONDOWN and WM_RBUTTONUP messages, the OnRButtonDblClk call, and another WM_RBUTTONUP message when the button is released.
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.
