Measurement Studio
If you program your NI-DAQmx-supported device in Measurement Studio
using Visual C++, Visual C#, or Visual Basic .NET, you can interactively
create channels and tasks by launching the DAQ Assistant from MAX or
from within Visual Studio .NET. You can generate the configuration code
based on your task or channel in Measurement Studio. Refer to the
DAQ
Assistant Help
for additional information about generating code. You also
can create channels and tasks, and write your own applications in your
ADE using the NI-DAQmx API.
For help with NI-DAQmx methods and properties, refer to the NI-DAQmx
.NET Class Library or the NI-DAQmx Visual C++ Class Library included
in the
NI Measurement Studio Help
. For general help with programming in
Measurement Studio, refer to the
