Programatically sample all channels from MAX configuration

[postformac]

I am distributing an exe and looking to provide the end user with the ability to set-up their own input channels to read through a cDaq / cRIO.

I know that I can distribute MAX with my installer which gives the end user the ability to configure their own channels. What I can't figure out is how to deal with this in my program to be able to read the samples as I don't know what the channels are in advance.

I have been experimenting with the DAQmx property nodes and can read the available tasks / channels / channel types from the attached hardware, however I'm not sure how to deal with the various sample rates etc to get a read on all of the channels.

Two questions -

Is there a simpler way to just "sample all available channels" or do you have to do this manually per channel through the property nodes?

If doing it manually through property nodes, could someone advise me on how to deal with the differing sample rates from different tasks? For example, I have one task set at the moment for a number of thermocouple inputs that are all at 10Hz and a separate task for a counter input that is only running at 2Hz. If I try to use a 10Hz loop to read each one in turn I get a big delay every time it samples from the counter task as it is not ready yet. If I was hard coding it I would just have two loops running at different rates but I can't figure out how to do this if I don't know it is needed in advance.

Any help would be appreciated, thanks.
