Using ON_UPDATE_COMMAND_UI in Property Pages

1. Use class wizard to create a new class called CMyPropSheet with a base class of CPropertSheet.
2. In the header add the message function. afx_msg LRESULT OnIdleUpdateCmdUI(WPARAM, LPARAM);
3. In the source file #include afxpriv.h
4. Add the message map ON_MESSAGE(WM_KICKIDLE, OnKickIdle)
5. Implement the function.

LRESULT CMyPropSheet::OnKickIdle(WPARAM, LPARAM)
{
	SendMessageToDescendants(WM_WM_KICKIDLE, 0, 0, FALSE, FALSE);
	return 0;
}

In the property page class, just add a message map for WM_KICKIDLE and call UpdateDialogControls.

LRESULT CMyPropPage::OnKickIdle(WPARAM, LPARAM)
{
	UpdateDialogControls(this, FALSE);
	return 0L;
}

P.S. This does not work for modeless property sheets. You need to trap the WM_IDLEUPDATECMDUI message in the property sheet's owner window and send it WK_KICKIDLE messages.
