Platform SDK: MAPI

Adding a Send Command to an Application

Being able to add a Send command to a document-based application's File menu is a Microsoft Windows 95 logo requirement. The same logic applies to sending a message from any application.

Design Tasks

Decide whether to use Simple MAPI, CMC, MAPI, or the CDO Library. See Selecting a Client Interface.
Decide when to load and unload the selected interface, and when to create and destroy its session. You should share the messaging client's session, if it is active. See MAPI Sessions.

Implementation Tasks

Determine whether the Send command should be enabled. Installation of messaging support in the operating system is optional, and your Send command should be disabled if the selected interface is not available. See Determining Which Client Interfaces are Installed.
Load the selected interface DLL and the entry points you will need. See one of the following topics, depending upon which interface you have selected:
- For Simple MAPI, see Initializing a Simple MAPI Client.
- For CMC, see Starting a CMC Session.
- For MAPI, see Initializing MAPI and Initializing OLE for Use with MAPI.
- For the CDO Library, no explicit load step is necessary. Simply instantiate one of the top-level objects, MAPI.Session or MAPI.Message.
Send a document using the selected interface. See one of the following topics, depending upon which interface you have selected:
- For Simple MAPI, see Sending Messages with Simple MAPI.
- For CMC, see Sending Messages with CMC.
- For the CDO Library, see Creating and Sending a Message.
- For MAPI, several steps are necessary:

1. Open the default message store. See Opening a Message Store.

2. Open the Outbox. See Opening a Folder.

3. Add recipients to the message's recipient table. See Recipients.

4. Add the document to the message as an attachment. See Attachments.

5. Optionally, add text to the message. See PR_BODY.

6. Send the message. See Sending Messages with MAPI.

7. Release all the objects created in the preceding steps.
