Decisions Behind the Design of the Queued Message Handler Template


This session describes the complete design of the Queued Message Handler (QMH) project template that ships with LabVIEW 2012 and later. This template is one of the starting points that NI recommends for multi-loop, parallel applications. This presentation begins by showing how the QMH compares to other design patterns. Then, it goes into detail about the design of the QMH, and the decisions behind that design. Next, it introduces a complete DAQ application built from the QMH template. Finally, the presentation discusses potential areas of expansion and customization of the QMH. This presentation is geared toward CLD-level developers who wish to standardize their application development. It would also be useful for developers aspiring toward CLD certification, as the QMH is an excellent template to use as a starting point when taking the CLD exam.
