Applies To: Windows 10, Windows 7, Windows 8, Windows 8.1, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows Server Technical Preview, Windows Vista

This example provides a function that receives the GUID of an existing public queue and returns the MSMQQueueInfo.PathName property for it, which can be used to display the path name of the queue. The queue GUID is supplied to this function as a string representation of the GUID in the form 12345678-1234-1234-1234-123456789ABC.

Note

The string must not include the braces normally used with GUIDs.

This function must retrieve information stored in the directory service to return the path name of an existing public queue.

To retrieve MSMQQueueInfo.PathName

  1. Declare the objects needed to retrieve queue properties. This routine declares an MSMQQueueInfo object.

  2. Create the MSMQQueueInfo object. This example then uses MSMQQueueInfo.FormatName to set the format name to the format name created from the GUID string passed to the function.

  3. Call MSMQQueueInfo.Refresh to obtain the current registered settings of the queue properties.

Note

This call retrieves the settings of all properties of the queue with the format name set. If no such queue exists, an error message is displayed

  1. Return the local setting of MSMQQueueInfo.PathName.

Code Example

The following code example can be run on all versions of Message Queuing.

Function GetQueuePathname( _  
                          QueueGuid As String _  
                          ) As String  
  Dim qinfo As MSMQQueueInfo  
  
  ' Create the MSMQQueueInfo object.  
  Set qinfo = New MSMQQueueInfo  
  qinfo.FormatName = "PUBLIC=" & QueueGuid  
  On Error GoTo ErrorHandler  
  
  ' Retrieve the internally registered property values.  
  qinfo.Refresh  
  
  'Return the local setting of MSMQQueueInfo.PathName  
  GetQueuePathname = qinfo.PathName  
  Exit Function  
  
ErrorHandler:  
  MsgBox "Error " + Hex(Err.Number) + " was returned." _  
          + Chr(13) + Err.Description  
End Function
