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.

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.

Tip For more information on how to create user code, refer to the Using a DAQmx Task

Class in a Project topic in the NI Measurement Studio Help.

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.
