Hi, Jeff,

Thanks!

I have to sample 2 channels at the same time.   Is DAQmxReadAnalog1ChNsamplesdbl for just 1 channel?

Also, where can I find all the commands that are available for VB6?  So far, I have seen DAQmxReadAnalogScalarF64, DAQmxCfgSampClkTiming, and DAQmxReadAnalog1ChNsamplesdbl.  Are there others?

yes.  DAQmxReadAnalogNChNsamplesdbl returns a 2d array

Hi, Jeff,

VB6 cannot find either DAQmxReadAnalog1ChNsamplesdbl or  DAQmxReadAnalogNChNsamplesdbl.  Do I have to include specific componenet or references into VB6?  It did find DAQmxReadAnalogScalarF64, though.

Hi Pei,

The Visual Basic 6 and C API use a lot of the same function calls, if you look at the DAQmx C Reference help and the DAQmx C API Visual Basic 6.0 Help. You can see what read function are avail and you can find the function prototype and definitions of these functions. The DAQmxReadAnalogScalarF64 command will only read one value from one channel the  DAQmxReadAnalogF64 can read from multiple
