Invokes the property page help in response to an end-user request.
HRESULT Help(
LPCOLESTR pszHelpDir //Pointer to string from HelpDir key
);
This method supports the standard return values E_OUTOFMEMORY and E_UNEXPECTED, as well as the following:
Calls to this method must occur between calls to IPropertyPage::Activate and IPropertyPage::Deactivate.
If the page fails this method (such as E_NOTIMPL), then the frame will attempt to use the pszHelpFile and dwHelpContext fields of the PROPPAGEINFO structure obtained through IPropertyPage::GetPageInfo. Therefore, the page should either implement IPropertyPage::Help or return help information through IPropertyPage::GetPageInfo.
Windows NT: Use version 4.0 or later.
Windows: Use Windows 95 or later.
Windows CE: Unsupported.
Header: Declared in ocidl.h.
