LabVIEW
how can i configure multiple channels using daqmx?
The easiest way is through the Measurment & Automation Explorer
(MAX) by creating a DAQmx Task and configuring each channel
differently. You can select multiple channels for the task then change
each one to the configuration needed.
If you need help getting this setup, let us know and we can walk you through it.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.
So you want to be able to configure/reconfigure the channels from a front panel in LabVIEW?
This can be done, but is not really a trivial task. There are caveats as well. The main one being you can't reconfigure a channel without stopping all the tasks on that card. (at least I haven't found a way)
Can you give a few more details?

The attached VI shows basically what you need to do to programatically
create a multi-channel task in LabVIEW where each channel can be
configured with its own values.
This creates an empty task, then configures each channel and adds it to the task. This would probably work better using arrays and For loops, but I just threw this together quick.
What you'll need to do is come up with a dialog that the user can enter all the configuration values and pass them to the "Create Channel" VIs and the Channel property nodes.

Probably, but I"m not sure. I usually just try it and see what happens. You'll either get an error or not, it won't hurt anything.
