Measurement Studio User Manual
Tip
For more information on how to create an NI-DAQmx user interface, refer to the
Using a .NET DAQ Component in a Project
topic in the
NI Measurement Studio Help

Creating NI-DAQmx User Code in Visual C++
Note
Measurement Studio 8.5 support for Visual Studio 2008 does not include support for
Visual C++.
You can create NI-DAQmx user code in Visual C++. The DAQmx User
Code wizard wraps the configured DAQmx task class in a user-friendly
class and creates a dialog that provides an example of using the new class.
You can use the user code in two different ways. You can call the
DoModal
function on the new dialog class, or you can use the user-friendly wrapper
class directly in your code by calling the class programmatically.
To use the user code directly, create an instance of the DAQmx user code
class and call the appropriate function in your source code. You can create
an instance of the user code directly in source code, just as you create an
instance of any class directly in source code. Declare a variable of the
appropriate type and use it directly. The
.h
file for the user-friendly
wrapper for the DAQmx task class contains additional information on using
the user code.

Class in a Project

Creating an Instrument Control Application
To create a Measurement Studio instrument control application, use the
Instrument I/O Assistant. The Instrument I/O Assistant, as shown in
Figure 4-5, integrates into Visual Studio as a code designer. Use the Add
New Item wizard to add an instrumentation task to your project, and use the
Instrument I/O Assistant user interface to create and configure the
instrumentation task. The Instrument I/O Assistant generates a Visual
Basic .NET, Visual C#, or Visual C++ class that includes the functionality
you configure in the user interface. Use this assistant to help you write code
that communicates with devices such as serial, Ethernet, or GPIB
instruments.
Note
The Instrument I/O Assistant is available only if you have installed either the
Measurement Studio Professional or Measurement Studio Enterprise package.
