/* From askjf.com:
* It's often the easiest to build your application out of plain dialog (DialogBoxParam() or CreateDialogParam())
* Use Get/SetWindowLong(hwnd,GWL_USERDATA) (or GWLP_USERDATA for x64) for "this" pointers, if an object owns the dialog. Set it in WM_INITDIALOG, and get it for other messages.
* On the same token, when the owner object has a dialog, it's good to do the following:
o The object's constructor sets m_hwnd to 0.
o The object's destructor does if (m_hwnd) DestroyWindow(m_hwnd);
o WM_INITDIALOG sets this->m_hwnd to hwndDlg
o WM_DESTROY clears this->m_hwnd to 0
