error -50103 when I am trying to access two channels on USB 6366 board in the same time

I am trying to use two DAQmx tasks attempting to access two channels from
USB-6366 in the same time. But it gives me an error Error -50103. So I looked
online and find out it says ' It is not possible to have multiple DAQmx tasks
attempting to access the same physical device. '. So I am wandering how can
collect data from my ai0 and ai1 channels in the same time? Here is my code,
and please help me out. Thanks very much

Simple - use a single task with multiple channels. Surely the answers in all of the related posts said that. The channel list is just dev1/ai0:1.
