CNiReal32Matrix supported for CNiDAQmxAnalogMultiChannelReader?

[bgreengmw]

I am trying to use CNiReal32Matrix instead of CNiReal64Matrix with CNiDAQmxAnalogMultiChannelReader and don't see it available in the header file and will not compile. I am running version 8.1 of Measurment Studio with a NI6251 card.

Hi BGreenGMW,

NiDAQmxAnalogMultiChannelReader.h includes NiScalarMatrix.h, which defines a typedef for both matricies:

typedef

CNiScalarMatrix<Real32> CNiReal32Matrix;

typedef

CNiScalarMatrix<Real64> CNiReal64Matrix;

I tried defining a variable:

CNiReal32Matrix myMatrix;

in a DAQmx example program (AcqMultVoltageSamples_SWTimed), and it compiled successfully. 

Can you please reply with a sample program that failed to compile with a CNiReal32Matrix, yet compiles with a CNiReal64Matrix?
