To develop an NI-FGEN application in LabWindows/CVI, follow these
general steps:
1.
Open an existing or new project file.
2.
Load the NI-FGEN function tree (
niFgen.fp
) from

steps:
1.
Open an existing or new Visual C/C++ project.
2.
Create source files—
.c
(C source code) or
.cpp
(C++ source
code)—and add them to the project. Make sure that you include the
NI-FGEN header file (
niFGEN.h
) in your source code files as follows:
