CBasePropertyPage.IsPageDirty method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The IsPageDirty method indicates whether the property page has changed since it was activated or since the most recent call to IPropertyPage::Apply. This method implements the IPropertyPage::IsPageDirty method.
