Hi,
Thanks for the link but I had come across this before and if I was rude in my
answer then it was unintentional and I apologise.The main point of my question
was how to return my domain object to the web layer from the EndPeek event
handler defined below:
private void ReceiveQ_PeekCompleted(object sender, PeekCompletedEventArgs e) {
MessageQueue messageQueue = sender as MessageQueue; using
(Message message = messageQueue.EndPeek(e.AsyncResult)) { if
(!message.CorrelationId.Equals(_correlationId)) {
messageQueue.BeginPeek(_timeOut); return; } }
using (Message message =
messageQueue.ReceiveByCorrelationId(_correlationId)) { //DO
processing }}
I defined a custom event which is raised back to the Ui layer which is outlined
below:
using (Message message = messageQueue.ReceiveByCorrelationId(_correlationId))
{
try
{
XmlDocument doc = new XmlDocument();
doc.LoadXml((string)message.Body);
if (MessageProcessed != null)
{
_receiveQ.EndPeek(e.AsyncResult);
MessageProcessed(this, new MSMQEventArguments<XmlDocument>(doc));
}
}
catch (Exception ex)
{
log.Error("Dom loading error", ex);
}
}
MessageProcessed is the custom event I have created. I take it this is the best
way to do this?
I would be curious to know what are the steps involved in making this whole
process asynchronous?
My method call starts out like this:
public void CalculateOrder(ShoppingCart cart, OrderCalculatedHandler
orderCalculatedHanlder)
{
try
{
OrderBuilder orderBuilder = new
OrderBuilder(OrderBuilder.OrderMessage.CALCULATEORDER);
MSMQHelper helper = new MSMQHelper();
helper.MessageProcessed += new
MSMQMessageProcessedHandler(Helper_MessageProcessed);
OrderCalculated += new OrderCalculatedHandler(orderCalculatedHanlder);
helper.RequestAsync(orderBuilder.Build(cart));
}
catch (Exception ex)
{
log.Error("MSMQHelper.Request", ex);
throw ex;
}
}
How would I turn this into an async method and do you think it really is worth
my while going down this route?
I’m not asking for the code, just some advise off some people with experience
of this.
