// Property Page messages
//=--------------------------------------------------------------------------=
// in addition to regular windows messages you'll receive for a dialog box,
// you'll receive the following messages in your property page implementation:
//
// PPM_NEWOBJECTS:
//    wParam = 0;
//    lParam = (LPARAM)(HRESULT *)&hr
//
//  - in this message, you should call FirstControl() to get a pointer to a
//    control, and initialize the values in the property page dialog with
//    values from the control object.  put results from the operation in
//    the HRESULT pointed to by LPARAM.
//
// PPM_APPLY:
//    wParam = 0;
//    lParam = (LPARAM)(HRESULT *)&hr
//
//  - this message is sent to your dialog whenever the user clicks APPLY or OK
//    in the dialog.  you should have a loop with the following code in it:
//
//      for (pUnk = FirstControl(&dwCookie) ; pUnk; pUnk = NextControl(&dwCookie)) {
//            hr = pUnk->QueryInterface(IID_IMyCtlInterface, (void **)&pMyCtl);
//            // set properties here!!!
//      }
//
//    call PropPageException() if there is an error while setting propertites
//    to show the exception set up by the property set routine.
//
// PPM_EDITPROPERTY:
//    wParam = dispid
//    lParam = (LPARAM)(HRESULT *)&hr
//
//  - sent to your dialog when somebody wants you to set the focus to a specific
//    property [typically, one will see a call to this when one returns a page
//    from IPerPropertyBrowsing::MapPropertyToPage].  you can use this
//    to bring up dialogs, or do whatever flaps your flagella.
//
// PPM_FREEOBJECTS:
//    wParam = 0
//    lParam = (LPARAM)(HRESULT *)&hr
//
// - sent to your dialog when you should free up any objects.  some people will
//   find it interesting to QI and store objects in the PPM_INITOBJECTS message.
//   this message tells the prop page that these objects are no longer valid,
//   and any stashing of objects should be terminated.
