How To Access NI-DAQmx in a LabVIEW Project

[lvb]

In the "Project Explorer" for a .lvproj file, you can create NI-DAQmx tasks/scales/channels. I am looking to modify these dynamically and achieve the following goals:

How to read all channels/tasks/scales in a project?

How to write a channel/task/scale in a project?

How to delete a channel/task/scale in a project?

Below is some code I used to detect what DAQmx items exist, but how can I acess them using the DAQmx property nodes dynamically?

Thanks

I know it's kin-of brute force, but the lvproj file is just an XML file - you could edit it and then reload it...

Maybe we need to start a new wiki article on the lvproj file structure (just like the one we've already got for the LabVIEW.ini file)?

I was attempting to use the XML file as a last resort. Has anyone made any discoveries if using DAQmx property nodes?

Well first to get all tasks from a project you could get all descendents and filter for DAQmx tasks as type.

Then I think you can call most of the DAQmx functions with a string instead of a DAQmx datatype.

I don't have DAQmx installed on my current computer but it should work.
