HOWTO: How to Write an MSMQ Trigger Application

SUMMARY

Microsoft Message Queue Server (MSMQ) does not come with "trigger" functionality for queues. A "trigger" is a software component that monitors a queue for a certain condition and performs some action when that condition is met. Currently, trigger functionality must be implemented in the application. The MSMQ software development kit (SDK) provides documentation on how to use notification events to provide asynchronous handling of messages, which is one kind of trigger functionality. However, you can also use Performance Monitor counters to monitor for triggering conditions. This article points you to a sample application that shows you how to write a trigger using a Performance Monitor counter.
