| Platform SDK: CDO 1.2.1 |
The CDO libraries call Microsoft COM and MAPI interfaces for you. The following table describes the MAPI interfaces that the CDO Library calls when you manipulate a CDO Library object.
| CDO Library object |
COM or MAPI interface called by the CDO Library |
|---|---|
| AddressEntry | IMailUser |
| AddressEntryFilter | IMAPITable (with Restrict method) |
| AddressList | IABContainer |
| Attachment | IAttach |
| Field | IMAPIProp, IStream |
| Folder | IMAPIFolder |
| InfoStore | IMsgStore |
| Message | IMessage |
| MessageFilter | IMAPITable (with Restrict method) |
| Recipient | IMAPITable row (recipient table from IMessage) |
| Session | IMAPISession |
For collection objects, the CDO libraries call the MAPI interface IMAPITable.
The CDO libraries also call the MAPI interface IMAPIProp. Many of the properties exposed by the CDO libraries are based on MAPI properties. The following table describes the mapping between these CDO library properties and the underlying MAPI properties.
