How to Include Return Receipt Functionality w/ MAPI Control

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
				

Below is the example code that traps whether Request Receipt has been set. Place this code at the point where the user reads the message.

   If mapimessages1.MsgReceiptRequested Then          ' Check Return
receipt
      mapimessages1.MsgIndex = -1                     ' Compose buffer
      mapimessages1.RecipDisplayName = sender$        ' Set sender to
receiver
      mapimessages1.MsgSubject = "RECEIVED " + title$ ' Set message title
      mapimessages1.Action = MESSAGE_SEND             ' Send Return Receipt
   End If
				

The variables sender$ and title$ contain the alias and the message title of the original message.
