LabVIEW and LabWindows/CVI are innovative program development 
software packages for data acquisition and control applications. LabVIEW 
uses graphical programming, whereas LabWindows/CVI enhances 
traditional programming languages. Both packages include extensive 
libraries for data acquisition, instrument control, data analysis, and 
graphical data presentation. Using LabVIEW or LabWindows/CVI can 
significantly reduce the development time for your data acquisition and 
control application.

LabVIEW features interactive graphics, a state-of-the-art user interface, 
and a powerful graphical programming language. The LabVIEW 
NI-SWITCH VI Library, a series of virtual instruments (VIs) for using 
LabVIEW with National Instruments switch hardware, is included with 
the NI-SWITCH driver. 

LabWindows/CVI features interactive graphics, a state-of-the-art user 
interface, and uses the ANSI standard C programming language. The 
LabWindows/CVI NI-SWITCH Library, a series of functions for using 
LabWindows/CVI with National Instruments switch hardware, is included 
with the NI-SWITCH driver.

The NI-SWITCH instrument driver also includes support files for 
Microsoft Visual C++ and Microsoft Visual Basic. Please see the 
NI-SWITCH readme file for version support information.
