Add page in customize dialog

Hi,

I need to add a page to the customize dialog. I did the following:

1. Add a new dialog resource to my application (with id = IDD_MY_PROP_PAGE)

2. Create a new class CMyPropPage which derives from CPropertyPage and from CXTPDialogState (and have enum IDD = IDD_MY_PROP_PAGE).

3. in OnCustomize of the MainFrame I added:

    CMyPropPage mypage(&cs);

    cs.AddPage(&mypage);

I get an Abort in CPropertyPage::PreProcessPageTemplate. in LockResource method I get pTemplate = NULL.

Can someone please help ?

Yoav.
