That it! Please I need help

[Chris]

Hi,
I have MSMQ installed on my domain controller (Win 2003) and on my XP client
(developer box). I created a private queue under private queues.

I am able to write messages to the queue like

str = "FormatName:Direct=TCP:xx.xx.xx.xx\PRIVATE$\testqu eue"

Dim msgQ As MessageQueue
Dim txt As String

txt = "From Sec PC"

Try

msgQ = New MessageQueue(str)
msgQ.Send(txt, "PC TESTing")
Catch ex As Exception

MsgBox(ex.Message)

End Try
but I am unable to retrieve message from the queue like this

Dim msgQ As MessageQueue = New MessageQueue(str)
Dim msg As Message

Try
msgQ.SetPermissions("user",
MessageQueueAccessRights.FullControl, AccessControlEntryType.Set)

msgQ.Formatter = New XmlMessageFormatter( _
New Type() {GetType(System.String)})
msg = msgQ.Receive
MessageBox.Show(msg.Body)
Catch ex As Exception

MsgBox(ex.Message)

End Try
I get the error

"The specified format name does not support the requested operation. For
example, a direct queue format cannot be deleted.

Please help. I have been trying for days on this.

Thanks

It would help if you'd say which line threw that exception.

Hi,
I think the error is here

msgQ.Formatter = New XmlMessageFormatter( _
' New Type() {GetType(System.String)})

That sounds unlikely, because you're not doing any operations on that
line.

When you say you *think* the error is there - what does the stack trace
say?

I don't get any stack trace. That's because of

Catch ex As Exception

MsgBox(ex.Message)

End Try

so it shows

"The specified format name does not support the requested operation. For
example, a direct queue format cannot be deleted"

Well that's your code which is stopping you from seeing the stack
trace, isn't it? You should be able to change it so that you *can* see
the stack trace.

An unhandled exception of type 'System.Messaging.MessageQueueException'
occurred in system.messaging.dll

Additional information: External component has thrown an exception.

But if you display the stack trace from the exception (rather than just
the message), you'll have a more detailed idea of what's going on.

Sorry about that. Here is the stack
---------------------------
msmqRec
---------------------------
at System.Messaging.MessageQueue.SetPermissions(Acces sControlList dacl)

at System.Messaging.MessageQueue.SetPermissions(Strin g user,
MessageQueueAccessRights rights, AccessControlEntryType entryType)

at msmqRec.Form1.Button1_Click(Object sender, EventArgs e) in
c:\Projects\Programs\VisualBaic.Net\MSMQ\msmqRec\m smqRec\Form1.vb:line 117
---------------------------
OK

Right, that tells a far clearer story.

Now, if you have a look at the docs for MessageQueue.SetPermissions,
you'll see that you can't set the permissions on a queue on a remote
computer.

Ok I see. Excluding the permission, how can I access the private on the
remote server from one pc but not on the other. The only difference is the
the pc that can access the private queue is on the domain but the other is
not which brings me to another queston:
Is it possible to access a remote private queue for a pc not on the domain?

That I don't know, I'm afraid - I'm not a message queue expert, I'm
afraid. I suggest you ask on an MSMQ newsgroup - it sounds like an MSMQ
issue rather than a .NET one as such.
