Is CPropertyPage::SetModified what you're after?

Thanks for David's response.

CPropertyPage::SetModified() will enable/disable the Apply button on
property sheet. My problem is when user clicked OK button on
CPropertySheet, I need to know which CPropertyPage has been modified.

Do I have to keep track by myself? Is there a build-in method in MFC to do
it? Any response will be appreciated!!!

Hi Hao,

The only way I've been able to implement this functionality is manually
calling SetModified in child window OnChange, OnSelectChange, etc.
handlers.

Here is a VC1.52c answer.

There is a way to tell the property that it has changed 'SetModified( BOOL
)' but no way to ask if its been changed. SetModified sets a private flag
m_bChanged but there is no way to read it. I just added one line to the
class definition:

inline BOOL IsModified( ) { return m_bChanged; }

in file afxdlgs.h for the CPropertySheet definition. Helps out
tremendously. Hope this helps you.
