Hello,

NI-DAQmx should ship with 3 counter examples for VB .NET at: C:\Users\Public\Documents\National Instruments\NI-DAQ\Examples\DotNET<version>\Counter\Measure Digital Frequency

You can also open examples in Visual Studio by going to Measurement Studio >>  Measurement Studio Examples and navigating to

The three examples are:

1. MeasDigFreqBuffCont_ExtClk_ArmStart -- which is continuous acquisition based on an external clock and a trigger
2. MeasDigFreqBuffCont_LargeRange2Ctr -- also a continuous example
3. MeasDigFrequency_LowFreq1Ctr -- not continuous, as you noted

In both the continuous examples, you can see that clicking the Start button creates and starts the DAQmx Task, the reading is done in a CounterInCallback function, and the Task is stopped and  Disposed when the Stop button is clicked. Hope these examples help!
