Using ON_UPDATE_COMMAND_UI in Property Pages

Using ON_UPDATE_COMMAND_UI message maps in property pages is the same as in dialogs except for one extra step required.
You need to derive a class from CPropertySheet and intercept the WM_KICKIDLE messages.

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;
}

The property sheet now passes all WM_KICKIDLE message to its property pages.

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;
}

Then all you need is ON_UPDATE_COMMAND_UI message maps.

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.

    I too have used this method.  However, instead of use SendMessageToDescendents, I use 
    
    

    CPropertyPage* pActivePage=GetActivePage();
    if (NULL==pActivePage)
    return lParam <= 2;

    return pActivePage->SendMessage(WM_KICKIDLE, wParam, lParam);

    This way, I only send the message to the active page, as it is the only one I'm interested in updating.

    Your post gets me what I need, thanks.

    Picky, I know, but...
