LabWindows/CVI

Within LabWindows/CVI, the NI-DNET function panel is located in
Library»NI-DNET. Like other LabWindows/CVI function panels, the
NI-DNET function panel provides help for each function and the ability to
generate code.

The reference for each NI-DNET function is provided in the NI-DNET
Programmer Reference Manual
. You can access reference for each
function directly from within the function panel.

The header file for NI-DNET is

nidnet.h

. The library for NI-DNET is

nidnet.lib

.

The NI-DNET software includes a full set of examples for
LabWindows/CVI. The NI-DNET examples are installed in the

LabWindows/CVI

directory under

samples\nidnet

. Each example

provides a complete LabWindows/CVI project (

.prj

file). A description

of each example is provided in comments at the top of the

.c

file.

When you compile your LabWindows/CVI application for NI-DNET,
it is automatically linked with

nidnet.lib

, the link library for

LabWindows/CVI. When NI-DNET is installed, the installation program
checks to see which compatible C compiler you are using with
LabWindows/CVI (Microsoft or Borland), and copies an appropriate

nidnet.lib

for that compiler.

Microsoft Visual Basic

To create an NI-DNET application in Visual Basic, add the

nidnet.bas

file to your project. This allows you to call any NI-DNET function file from
your code.

The

nidnet.bas

file is located in the

MS Visual Basic

folder of the

NI-DNET

folder. The typical path to this folder is

\Program Files\

National Instruments\NI-DNET\MS Visual Basic

.

The reference for each NI-DNET function is provided in the NI-DNET
Programmer Reference Manual
, which you can open from Start»All
Programs»National Instruments»NI-DNET
.

You can find examples for Visual Basic in the

examples

subfolder of the

MS Visual Basic

folder. Each example is in a separate folder. A

.vbp

file with the same name as the example opens the Visual Basic project. A
description of the example is located in a Help form within the project.
