// 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.
