[archive] MSMQ - Microsoft Messaging

[Migrated content. Thread originally posted on 21 April 2005]

Has anyone tried to incorporate Private message queues in acucobol.? I am needing to interface a 3rd party application using MSMQ and private message queues..

Any help is greatly appreciated.

Thanks
Jason

Using MSMQ in Acucobol is no problem at all.

Create a msmq.def file using AXDEFGEN on the Microsoft Message Queue Object Library, off the Libraries tab. Include the msmq.def file in the special-names.

Then in WS you need something like:
WORKING-STORAGE SECTION.
*=======================
*
77 mqdest HANDLE of MSMQDestination.
77 mqmess HANDLE of MSMQMessage.

In PROCEDURE DIV do:
CREATE MSMQDestination OF MSMQ HANDLE IN mqdest.
MODIFY mqdest PathName = ".\\private$\\myqueue".
MODIFY mqdest Open().

to open the private queue "myqueue".

to create a message do:
CREATE MSMQMessage OF MSMQ HANDLE IN mqmess.

to add "TEXT" to message body do:
MODIFY mqmess Body = "TEXT".

to send message do:
MODIFY mqmess Send(mqdest).

Do not forget to:
MODIFY mqdest Close().
DESTROY mqdest.
DESTROY mqmess.


to receive messages you need the following in WS:
77 mqmess HANDLE of MSMQMessage.
77 mqqinfo HANDLE of MSMQQueueInfo.
77 mqq HANDLE of MSMQQueue.
01 MISC.
10 MESSBODY PIC X(18).



then in PROCEDURE DIV do:
CREATE MSMQQueueInfo OF MSMQ HANDLE IN mqqinfo.
MODIFY mqqinfo PathName = ".\\private$\\myqueue".
MODIFY mqqinfo Open(MQ_RECEIVE_ACCESS,MQ_DENY_NONE) GIVING mqq.


Then create a message:
CREATE MSMQMessage OF MSMQ HANDLE IN mqmess.

Then pull a message off the queue by:
MODIFY mqq Receive() GIVING mqmess.
INQUIRE mqmess Body IN MESSBODY.
DISPLAY MESSBODY.
ACCEPT OMITTED.

Do not forget to:
MODIFY mqq Close().
DESTROY mqq.
DESTROY mqmess.
DESTROY mqqinfo.

This is in short what you need. If you like I have some sample programs to send and receive data. Works nice between VB and Acucobol, and it is awfully fast.

best regards,
Hans J

Hans J,

Thanks alot for the post...It's exactly what I needed.

Do you know of a way to load a message body of unknown size?

The 3rd party app I'm communicating with doesn't have a max on the message size to be passed...

Thanks again for your help..

Hello Jason,

What I usually do, if I don't know the message size, is create a WS item, to hold the message, of riduculous size, like 10MB or so.

Then, when the message has been received I think you can inquire it's size. Or you could count the number of trailing spaces to find out.

best regards,
Hans J

Hans,

Have you tried setting the Receivetimout on the Receive method?



Here's the code I'm using
Working Storage...

77 W-Var-ReceiveTimeout usage handle.



Procedure......
....
MODIFY mqq @Receive(
by name @ReceiveTimeout W-Var-ReceiveTimeout
)
GIVING mqmessr.



Here's the snippet from the def file.


* Method to synchronously retrieve a message from a queue. It always
* removes the first message in the queue regardless of the position of the
* implicit cursor. Optional parameters include ReceiveTimeout (default set
* to INFINITE), Transaction (default set to MTS Transaction),
* WantDestinationQueue (default set to False), and WantBody (default set
* to True).
METHOD, 1610743814, @Receive,
"VARIANT*" @Transaction, TYPE 16396,
"VARIANT*" @WantDestinationQueue, TYPE 16396,
"VARIANT*" @WantBody, TYPE 16396,
"VARIANT*" @ReceiveTimeout, TYPE 16396
OPTIONAL 4
RETURNING "IMSMQMessage*", TYPE 9



Thanks for the help.

Jason,

I have not tested this. But it looks quite interesting.

Thanks for the tip.
