MultiChannel Control in DAQmx

[mxx]

Hi  guys.

    I program the code to control the AO0 to output the volt. The code is in the Pic.

AO0 code

    While task of Output is starting, I control the AI0 to recieve the volt  volt wave. But the task is always failed.

    How can I simultaneous control  the AI0 and the AO0?

taskHandleInGB is initialized in the function getDAQAI()

If the task of taskHandleInGB  is started,it always be failed.
