Description

This package installs the DeQMH Project Template in the Getting Started>>Create Project window.

The DQMH project template is based on the National Instruments Queued Message Handler Project Template (NI QMH). The DQMH project template improves on the NI QMH by providing safe, event-based message handling and scripting tools to make development easy, encourage same style between different developers in the same project and improve efficiency.

DQMH modules are best used in applications where there needs to be multiple modules running in parallel that communicate with each other.

DQMH modules can also be used for applications that have a single module, where the developer would benefit from having an API Tester has the capability of eavesdropping on the different DQMH events and messages.

Each module is implemented following a variation of the National Instruments Queued Message Handler and it has a Test DQMH Module API.vi to help troubleshoot, debug and eavesdrop on the communications between the DQMH Module and its calling code.

Release Notes

6.0.0.91 (Jun 10, 2021)

1. #DQMH-694 Re-created the Main.vi for the Singleton and Cloneable module templates from scratch, making sure that their pane origin values make sense and are at (0,0)

2. #DQMH-696 Added a call to Update Module Execution Status.vi (with a 'Running?' value of FALSE) to Close Module.vi for our project template, CML project template, and module template. We also added a validate/fixer for the issue

3. #DQMH-697 Updated the scripting for the DQMH unit test teardown VI to use a Merge Errors for the incoming error so the Stop Module VI always executes. We also added a validate/fixer that checks for this issue

4. #DQMH-688 Creating a new module from template now works if the template exists in the project

5. #DQMH-685 Unbundle the reply in the Request and Wait for Reply (except for error). If there is not enough space for terminals, then the VI outputs the reply cluster as before. No validate/fixer tool

6. #DQMH-666 Updated the context help of the Start Module.vi and Synchronize Module Events.vi for both singleton and cloneable to better illustrate their use together

7. #DQMH-693 The Stop Module.vi for the My Cloneable Module.lvlib in our project template now has Fab's fix for Andreas 2.0, where we poll the module state at the end of stopping the module, if we're running as a singleton

8. #DQMH-638 Added support for parsing DQMH tags from the error source string in the 'Error Reported' broadcast VI. Added a validate/fixer tool

9. #DQMH-664 Made the MHL frame names with "---" prefixes have consistent spacing. Also fixed errant window position of 'Do Something Else and Wait for Reply' VI from singleton module

10. #DQMH-677 Updated Stop Module VI for singleton module to always stop the module regardless of incoming error. Updated testers for both singleton and cloneable to not do a Clear Errors when the event loop stops executing

11. #DQMH-686 Changed data type of Module ID input to Wait on Module Sync.vi to be an I32 instead of a U32. Included validate/fix tool

12. #DQMH-708 Don't show panel of singleton if not running. We changed the singleton template in DQMH 6.0 to broadcast an Update Module Execution Status of FALSE before closing. The application main VI in our project template needed to be updated to not try to show the panel of the singleton module if the module execution status is FALSE (since that means the module has stopped)
