Hi Kim. I don't know if this will help, but I guess its possible..
I'm using the Apache.NMS.ActiveMQ for C#. There, to acknowledge messages individually, we must chose the AcknowledgeMode.IndividualAcknowledge when instantiating a session and then call Message.Acknowledge for each message. Like: mySession = connection.CreateSession(AcknowledgementMode.IndividualAcknowledge); (...) myMessage.Acknowledge(); It seems that there are analogous mechanisms in the library you're using: https://github.com/fusesource/fusemq-c/blob/master/fusemqc-client/src/main/cpp/CMS_Message.h Line 142: cms_status cms_acknowledgeMessage(CMS_Message* message); https://github.com/fusesource/fusemq-c/blob/master/fusemqc-client/src/main/cpp/CMS_Session.cpp Line 52: cms_status cms_createSession(CMS_Connection* connection, CMS_Session** session, CMS_ACKNOWLEDGMENT_MODE ackMode) Gabriel Almeida Goncalves Analista Superintendência de Desenvolvimento Diretoria de Desenvolvimento (31)3311-6739 ----- Mensagem original ----- De: "Timothy Bish" <tabish...@gmail.com> Para: "users" <users@activemq.apache.org> Enviadas: Quarta-feira, 5 de junho de 2019 15:09:10 Assunto: Re: Can consumers acknowledge/confirm receipt of a message versus auto acknowledgement?

It is unclear what you are asking for here, you reference a QueueBrowser implementation but are asking about consumer code so I'm not sure what you are looking to do. A QueueBrowser doesn't support any acknowledge types as it is a non-destructive view of messages on a Queue. The browser also makes no guarantees about it showing you every message on a Queue so if you are relying on that property then you will likely run into trouble. Looking at the source code for the C wrapper client a message consumer could have acknowledgment types other than auto specified, the values are here https://github.com/fusesource/fusemq-c/blob/master/fusemqc-client/src/main/cpp/cms.h#L82 > > Thanks!
