Multiple e-mail attachments cause error with MSMAPI OCX control that is included in Visual FoxPro

   *-- Attach the files.
   FOR lnCount = 1 TO ALEN(lcAttachment)
      oMessage.AttachmentIndex = lnCount - 1
      oMessage.AttachmentPathName = lcAttachment(lnCount)
   ENDFOR
				

   *-- Attach the files.
   FOR lnCount = 1 TO ALEN(lcAttachment)
      oMessage.AttachmentIndex = lnCount - 1
      oMessage.AttachmentPathName = lcAttachment(lnCount)

      *-- We have to increment the AttachmentPosition because two
      *-- attachments cannot occupy the same space.
      *-- The AttachmentPosition dictates the character position of the
      *-- attachment, so stick them in after the message.
      oMessage.AttachmentPosition = lnCount - 1
   ENDFOR
				

MORE INFORMATION

Note This code works with version 6.00.8023 of the Msmapi32.ocx control. If an earlier version of this control is installed, an error occurs when setting the LogonUI property. The Msmapi.ocx version 1.0.2815 ships with Visual FoxPro version 5.0. This code runs under Visual FoxPro 5.0; however, the later version of the MSMAPI32 control must be installed and registered.

The AttachmentPosition property determines the character position of an attachment within a message. This value can be programmatically set to any position within the message body. However, since the number of attachments may be unknown, it would be easiest to increment the AttachmentPosition property one character for each attachment.

Steps to reproduce the behavior

1. Place the following code in a program file and run the program:

         oSession = CREATEOBJECT("MSMapi.MapiSession")
         oMessage = CREATEOBJECT("MSMapi.MapiMessages")
   
         oSession.LogonUI = .t.
         oSession.SignOn
   
         *-- The message control needs to reference the session control's ID.
         oMessage.SessionID = oSession.SessionID
         oMessage.MsgIndex = -1
   
         *-- Set up our message and send it.
         oMessage.Compose
         oMessage.msgsubject = "Attachments sent using FoxPro and MAPI"
         oMessage.msgnotetext = "   Attached are some test files."
   
         *-- Create an array holding the attachment file names.
         DIMENSION lcAttachment(2)
         lcAttachment(1) = home()+ "samples\data\customer.dbf"
         lcAttachment(2) = home()+ "samples\data\customer.cdx"
   
         *-- Attach the files.
         FOR lnCount = 1 TO ALEN(lcAttachment)
            oMessage.AttachmentIndex = lnCount - 1
            oMessage.AttachmentPathName = lcAttachment(lnCount)
         ENDFOR
   
         *-- Send the message on its way.
         oMessage.send(1)
   								

2. A dialog box displays the following message:
   OLE Idispatch exception code 0 from MAPIMessages: Unspecified Failure has occurred.
