Could anyone throw light on how SubmitPurchaseOrder function is implemented. I can see only declarations for this in the code provided by Microsoft.

Any help would be greatly appreciated.

Praveen,

Remember the Client is sending to the Message Queue and the service is recieving from the queue. this is configured in the client app.config, where the client is configured to enque messages and later the sercvice willd deque them in its "public static void ProcessOrder(Object source,ReceiveCompletedEventArgs asyncResult)"

rememberthe client doesn't send directly the service its all indirect thru the message queue!

hope this helps

Hi Hassanh,

I want to Create a sample project which is similar to the above function

1. Using this function, I need to Submit messages to Message Queue.
2. Along with that I need to Clientby mentioning EndPoint Name
3. And a Service function which reads messages from Queue

Instead of using Svcutil.exe I would like to go for Service Reference.

Any help would be greatly appreciated.

Hi Praveen,

The sample you mentioned(in windows SDK for .NET 3.5) just demonstrate how to use the WCF netMsmqBinding to let a client application send MSMQ message via WCF programming interface. Andif youuse netMSMQbinding, all the underlying msmq message sending details has been hidden/encapsulated by WCFprogramming model.

And the msmqIntegrationBinding is used forcommunicatino between WCFendpoint and legacy msmqprogram. For example, the samplein following link just demonstrate using WCF client proxy to send message to to a legacy MSMQ queue(via msmqIntegrationBinding):

For your scenario, what is the actual result you want to achieve?

Hi Steven,

Thanks a lot.

I want to develop atleast 5 Client applications that handles msmqIntegrationBinding. Any client can send message to Message Queue first.

WCF Service should take care of receiving messages from Message Queue, process it and send the message to other client transactionally and without duplicates.

Any client can be down at any time and Clients may reside on different systems over LAN.

I prefer to install WCF Service and MSMQ in all systems where Clients are running.

In developing WCF Service/Client, I would like to go for Service Referencerather than SvcUtil.exe

I want to write client side as

TestServiceClient client =new TestServiceClient("EndPointAddress");
client.SubmitFunction1(message1);
client.SubmitFunction2(message2);

Any help would be greatly appreciated.

Hi Praveen,

One thing here is that WCF service automatically dequeues all messages from all clients. When you are using MSMQ it is always disconnected or offline mode oc communication, so even if the client app goes down after sending message to the Q, which is published by WCF service, it will be there till WCF service dows notdqueues it.

You also mentioned that you prefer to install WCF serviceand MSMQ on all machines, for what purpose you need this. THE WCF service will be onone central machine (the server machine probably) and all other machines inLAN will have client app installed with WCF proxy. You may have MSMQ installed on each client machine, but all the client applications will reffer Q exposed by WCF service ehich is publicQ define on centralachine (generally) and configured in WCF service.

One more important thing here is thatsince communication is thriugh MSMQ so no immediate response will be send by WCF service to client so operation contract define in WCF saervice must be configured as OneWay=true this means that they does not return any value they are VOID.

Hi,

Just I want to know about any settings that needs to be changed to make SubmitMsmqMessage visible in accepting proper parameters at Client side.

Hi Praveen,

Have you been able to create the example you proposed to build.
if yes, can you please share the code on how you implemented that.

Cheers
