(Introduced in MSMQ 3.0.) The FormatName property of the MSMQDestination object, which can represent one or more queues, specifies a public format name, private format name, direct format name, distribution list format name, multicast address format name, multiple-element format name, or the format name of a queue alias (when a queue alias is specified in MSMQDestination.ADsPath) for sending messages.

Setting this property initializes the MSMQDestination object for sending messages.

Data type: String
Run-time access: Read/write
Property FormatName As String  

Property Value

A String that contains a public format name, private format name, direct format name, distribution list format name, multicast address format name, multiple-element format name, or the format name of the queue alias specified in MSMQDestination.ADsPath.

Remarks

The FormatName property can be set by the sending application or by Message Queuing. The sending application must set this property when sending messages using multicast addresses or multiple-element format names. Message Queuing sets this property when the sending application specifies a distribution list, queue alias, or a single public queue using the MSMQDestination.ADsPath property.

Setting the FormatName property initializes the MSMQDestination object so that the object can be opened explicitly by calling MSMQDestination.Open or implicitly by referencing the object in MSMQMessage.Send and closes the object if it is open.

Setting the FormatName property also resets the MSMQDestination.ADsPath and MSMQDestination.PathName properties to zero-length strings.

When you use the FormatName property to send a message to a multiple-element format name, you create the multiple-element format name by concatenating any number of public format names, private format names, direct format names, multicast address format names, or distribution list format names.

Note

MSMQMessage.Send will return MQ_ERROR_INVALID_PARAMETER if you try to send a transactional message, with a MSMQMessage.Journal property of MQMSG_DEADLETTER (that is, with negative source journaling enabled), to a distribution list or multi-queue format name. To correct this, either send the message to a single queue at a time, or disable negative source journaling.

The FormatName property is a string, and Message Queuing COM components ignore any characters that follow the first Null character in a string without returning an error.

Example Code

The following code fragment shows how to specify a three-element format name in the FormatName property and send a message to the corresponding destination queues. The format name strings in this example may contain any public format name, private format name, direct format name, or distribution list format name.

Dim dest As New MSMQDestination  
Dim msg As New MSMQMessage  
dest.FormatName = strFormatName1 & "," & strFormatName2 & "," & strFormatName3  
msg.Send DestinationQueue:=dest
