Sample: ReplyAll
|
|||
|
|
|
|||
|
|
Purpose:
|
|||
|
|
This application demonstrates how to use the MSMQ Mail COM object library from VB.
|
|||
|
|
The application waits for a MSMQ mail message to be received on a given queue. When
|
|||
|
|
one arrives, it is prompted on the form, and a reply message is sent to all its recipients,
|
|||
|
|
excluding the queue itself.
|
|||
|
|
|
|||
|
|
Requirements:
|
|||
|
|
MSMQ must be installed.
|
|||
|
|
|
|||
|
|
Overview:
|
|||
|
|
When a ReplyAll application is started, the user has to specify a queue label and then
|
|||
|
|
click the Start button. The application then searches for a queue of type MSMQ mail
|
|||
|
|
service, with this label. If one is found, it is opened for receive access. Otherwise, the user
|
|||
|
|
is asked whether to create that queue. If the user chooses <20>yes<65>, the queue is created and
|
|||
|
|
opened for receive access. A timer is set, and every 50 msec the receive queue is checked
|
|||
|
|
for incoming mail messages. All messages in the queue are received in a loop.
|
|||
|
|
|
|||
|
|
Incoming message handling:
|
|||
|
|
|
|||
|
|
1. The message is parsed and displayed on the form. If it is a text message, the text is
|
|||
|
|
displayed as the content of the form. If the message is a form, all form field names
|
|||
|
|
are displayed, each followed by the field data.
|
|||
|
|
2. A reply message is prepared. <20>RE:<3A> is added to the subject if not already there. The
|
|||
|
|
receiving queue label is set as the sender address, and the mail message is sent back
|
|||
|
|
to the sender, as well as to all of the message's recipients, excluding the sender of the reply
|
|||
|
|
message. The reply message is of the same type as the received message. A reply field or string
|
|||
|
|
is added to it accordingly.
|
|||
|
|
|
|||
|
|
Clicking the Stop button then stops the application from receiving messages from the queue, and the queue is closed.
|
|||
|
|
|
|||

|
Comments:
|
|||
|
|
MSMQ Mail is not supported on computers without access to a directory service (DS disabled). In such case,
|
|||
|
|
the application will exit with an appropriate popup message.
