how to store acquired data without missing

[brahma]

Hi,

I am developing DataAcquisition project using NiDaqmx(NIPCI-6221) on VC++.

I need to read data from VoltageReadTask having more than one channel and need to display the data as LIVE GrAPH.For that we used

DAQmxRegisterEveryNSamplesEvent along with it's CallBack method.

I am copying data after each callback event and I am posting message to graph control to display the graph.But I am bothering about data loosing when I am copying data and displaying it.

Is there any solution in NI_Daq API ....If please help me.

Thanks and regards

Mahesh

Hi Mahesh,

Could you please post an attached ZIP file with the code?

Also, are you using Measurement Studio?  If so, what version?
