You can use the additional Image functions installed with NI-IMAQdx. 
These functions use the NI Vision memory management feature, which 
automatically allocates the memory for your image. To use these Image 
functions, first create an image using 

imaqCreate

, and then pass that 

image to an acquisition function.

NI-IMAQdx installs the following assemblies that enable .NET languages 
to interact with the driver software:

•

NationalInstruments.CWNIIMAQDX.Interop.dll

NationalInstruments.AxCWNIIMAQDXControlsLib.Interop.dll
