DQMH API description

This VI creates and initializes the message queue for a QMH Module. If the message needs to be different for the given module, then create a child class of Message Queue and override the appropriate methods.

This VI pulls messages off the Message Queue.

For a regular message, enqueue the message. For a priority message, enqueue it at the front of the queue.

Process an error that occurred in the Message Handling Loop, either by ignoring it, or generating an "Error" message.

Process an error that occurred in the Event Handling Loop, either by ignoring it, or generating an "Error" message.

Process an error that occurred in a Helper Loop, either by ignoring it, or generating an "Error" message.

Flush the message queue.

Release the message queue.

When this VI executes, it pops up an "About" box with license information pertaining to DQMH.

Returns DQMH version information.

Returns DQMH and LabVIEW legal information.

Returns the URL for the DQMH End User License Agreement (EULA).

Returns information for all detected DQMH modules in a project. Remember to close the module library references when you are done using them.

Note that this VI will not return DQMH modules that are inside PPLs.

Returns VI references to all event VIs in a given DQMH module, separated by event type. Remember to close the VI references when you are done using them.

Returns VI references to all VIs in the project that call the given request VI. Remember to close the VI references when you are done using them.

Returns VI references to all VIs in the project that contain an event structure registered for the broadcast event of the given broadcast VI. Remember to close the VI references when you are done using them.

Note that since this VI parses the diagrams of all VIs in the project, it may take a while to complete.

Pass this VI a project reference and it will validate all DQMH Modules in that project. Possible return values of this VI are:

ERROR: [description of error that occurred when trying to validate]

PASS: [n] Module(s) Validated

FAIL: [n] Module(s) Analyzed

…​

Pass this VI a DQMH Module library reference and it will validate that module. Possible return values of this VI are:

ERROR: [description of error that occurred when trying to validate]

PASS: [n] Module(s) Validated

FAIL: [n] Module(s) Analyzed

…​

Return event references to monitor the progress of DQMH validation. Use in conjunction with the 'Validate All DQMH Modules in Project.vi'.

See the 'Headless Validation Example.vi' for an illustration of how to use this VI to monitor validation progress.
