How to Include Return Receipt Functionality w/ MAPI Control

- Professional Edition of Microsoft Visual Basic programming system

  for Windows, version 3.0

SUMMARY

This article explains how to install return receipt functionality on a message sent in a Visual Basic application. When a message has return receipt functionality, it means that when the message you sent is opened by the recipient, a message is sent back to you to confirm that the message was opened by the recipient. The returned message typically contains the date, time, and original message subject.

MORE INFORMATION

In Visual Basic, you can send a message by calling the automatic dialog box or by manually programming the message properties.

Using the automatic dialog box, the sender can select the Return Receipt option in the Send Note dialog box.

To manually program Return Receipt functionality, use the following example as a guide:

   ' set up a session associated with the message:
   Const SESSION_SIGNON = 1
   mapisession1.Action = SESSION_SIGNON
   mapimessages1.SessionID = mapisession1.SessionID

   ' Send the message
   Const MESSAGE_SEND = 3
   mapimessages1.MsgIndex = -1                        ' The compose buffer
   mapimessages1.MsgNoteText = "How's it going?"      ' The message text
   mapimessages1.MsgOrigAddress = "FredBloggs"        ' Sender's alias
   mapimessages1.MsgSubject = "Hi"                    ' The message title
   mapimessages1.RecipDisplayName = "JoSmith"         ' Recipient's alias
   mapimessages1.MsgReceiptRequested = True           ' Request receipt
   mapimessages1.Action = MESSAGE_SEND                ' Send message

   If mapimessages1.MsgReceiptRequested Then          ' Check Return

      mapimessages1.MsgIndex = -1                     ' Compose buffer
      mapimessages1.RecipDisplayName = sender$        ' Set sender to

      mapimessages1.MsgSubject = "RECEIVED " + title$ ' Set message title
      mapimessages1.Action = MESSAGE_SEND             ' Send Return Receipt
   End If
