In LabVIEW, you can use the NI Example Finder to search or browse examples. NI–DCPower examples are classified by keyword, so you can search for a particular device or measurement function. In LabVIEW, select Help»Find Examples to launch the NI Example Finder. The NI Example Finder offers two ways to access all installed LabVIEW example VIs (including NI–DCPower examples) and their descriptions:
The NI Example Finder is also available in LabWindows/CVI by selecting Help»Find Examples.
You can also access all the installed NI–DCPower examples for LabVIEW and LabWindows/CVI at Start»All Programs»National Instruments»NI-DCPower»Examples .
Examples also are available online that demonstrate NI-DCPower functionality. Refer to ni.com/examples for these examples and for more information.
NI-DCPower no longer installs IVI Compliance Package. NI-DCPower supports IVI configuration and runtime, but no longer supports the following features:
If you want to use the above features, you must install IVI Compliance Package separately, either from ni.com/downloads or from the NI Device Drivers 2017 DVD.
You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes.
If the NI product you are installing uses Microsoft .NET 4.0, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.0 separately before you install NI software.
For more information about automating the installation of NI products, refer to the following KnowledgeBase articles:
Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions.
