Retrieve a message from the server.
Syntax
object.GetMessage( MessageNumber,
MessagePart, MessageData, [Options] )
Parameters
- MessageNumber
- Number of message to retrieve from the server. This value must
be greater than zero. The first message in the mailbox is message
number one.
- MessagePart
- The message part that will be retrieved. A value of zero
specifies that the complete message should be returned. If the
message is a multipart MIME message, message parts start with a
value of one.
- MessageData
- A string or byte array which will contain the data transferred
from the server when the method returns.
- Options
- An optional integer value which specifies one or more options.
This argument is constructed by using a bitwise operator with any
of the following values:
| Value |
Description |
| imapSectionDefault |
All headers and the complete body of the specified message
or message part are to be retrieved. The client application is
responsible for parsing the header block. If the message is a
MIME multipart message and the complete message is returned,
the application is responsible for parsing the individual
message parts if necessary. |
| imapSectionHeader |
All headers for the specified message or message part are
to be retrieved. The client application is responsible for
parsing the header block. |
| imapSectionMimeHeader |
The MIME headers for the specified message or message are
to be retrieved. Only those header fields which are used in
MIME messages, such as Content-Type will be returned to the
client. This is typically useful when processing the header for
a multipart message which contains file attachments. The client
application is responsible for parsing the header block. |
| imapSectionBody |
The body of the specified message or message part is to be
retrieved. For a MIME formatted message, this may include data
that is uuencoded or base64 encoded. The application is
responsible for decoding this data. |
| imapSectionPreview |
The message header or body is being previewed and should
not be marked as read by the server. This prevents the message
from having the imapFlagSeen flag from being
automatically set when the message data is retrieved. |
Return Value
A value of zero is returned if the method succeeds.
Otherwise, a non-zero error code is returned which indicates the
cause of the failure.
Remarks
The GetMessage method is used to retrieve a message from
the server and copy it into a local buffer. This method will cause
the current thread to block until the message transfer completes, a
timeout occurs or the transfer is canceled. During the transfer, the
OnProgress event will fire periodically, enabling the
application to update any user interface objects such as a progress
bar.
