以Outlook object model or PIA为例

COM Add-ins一般使用Outlook object model.
托管代码使用PIA或者通过COM interoperability layer使用outlook object model.

Explorer:

Represents the window in which the contents of a folder are displayed.

Inspector:

Represents the window in which an Outlook item is displayed.

AppointmentItem:

Represents an appointment in the Calendar folder. AnAppointmentItem object can represent a meeting, a one-time appointment, or a recurring appointment or meeting.

MAPIFolder:

Folders within the Outlook data store can be typed; for example, the Calendar folder will only containAppointmentItem objects and the Contacts folder will only containContactItem andDistListItem objects.

Windows Common Data Types:

//A BSTR is a pointer to a null-terminated character string in which the string length is stored with the string.

typedef WCHAR* BSTR;

//The LPSTR type and its aliasPSTR specify a pointer to an array of 8-bit characters, which MAY be terminated by a null character.

typedef char* PSTR, *LPSTR;

//The LPWSTR type is a 32-bit pointer to a string of 16-bitUnicode characters, which MAY be null-terminated.

typedef wchar_t* LPWSTR, *PWSTR;

//An LPCSTR is a 32-bit pointer to a constant null-terminated string of 8-bit Windows (ANSI) characters.

typedef const char* LPCSTR;

OLE Automation Data Types:

typedef [string] wchar_t* LPOLESTR;
