Can create DAQmxCreateDIChan and DAQmxCreateDOChan in the same task.

Hi,

       Can we create DI and DO channel in the same task? Below is my coding but if used the same task it show error message.

         Error Msg  = 

Task cannot contain a channel with the specified channel type, because the task already contains channels with a different channel type.

Create one task for each channel type.

Code =

' Create the DAQmx task.
DAQmxErrChk DAQmxCreateTask("", vTaskHwnd)
' Add a digital input channel to the task.
DAQmxErrChk DAQmxCreateDIChan(vTaskHwnd, DIPortAddress, "", DAQmx_Val_ChanForAllLines)
DAQmxErrChk DAQmxCreateDOChan(vTaskHwnd, DOPortAddress, "", DAQmx_Val_ChanForAllLines)
'Start the task running, and read from the digital lines.
DAQmxErrChk DAQmxStartTask(vTaskHwnd)

vTaskIsRunning = True

Thank you very much.
