Return to NI Tools Network Software Requirements


Requirement Additional Resources
Packaging and Installation VI Package Manager: An Introduction
The add-on is packaged with VI Package Manager. VI Package Manager: How to Create a Package
The package is configured for required and/or incompatible VI Packages. VIPM Support: Package Configuration
The package includes a EULA which complies with the “Restrictions” and “Application Deployment” sections of the NI Software License Agreement.  
The package supports at least the latest LabVIEW version. VIPM Documentation: Install Requirements
The package description outlines software and hardware requirements and incompatibilities. VIPM Documentation: Description
If the package requires LabVIEW or VIPM to be run with administrator privileges, the package description communicates this to the user. Checking LabVIEW Administrator Privileges
[Recommended] Package either checks for required software or prompts the user to manually check for required software. Example: Detect Hardware Drivers Before Loading a VI
Licensing and Activation Choosing the Correct Licensing Method
[Recommended] The add-on utilizes the NI License Manager (NILM) 3rd Party SDK for licensing. NI License Manager Third-Party SDK 
The add-on is able to be evaluated immediately upon downloading the software.  
Users are reminded of the remaining trial time or uses.  
Upon the trial expiring, users are prompted to activate the add-on.  
The add-on can be activated using appropriate credentials.  
If the add-on is not using NI License Manager (NILM) 3rd Party SDK , activation instructions must be placed in the detailed help.  
Examples Example VI Guidelines
The add-on includes examples that demonstrate typical use cases to help the user get started. If examples are not appropriate for the add-on, a step-by-step tutorial should be added to the add-on's documentation. VI Package Manager: Adding Examples, Help, and Tools Menu Items 
Examples are integrated into the Task or Directory view of NI Example Finder. LabVIEW Example Finder Hints
Examples include VI descriptions viewable from NI Example Finder.  
Instructions on the front panel of example VIs describe exactly which steps the user must follow to run the example.  
Example VIs are not part of a licensed library.  
Example VIs contain unlocked, viewable block diagrams.  
Example VI front panels and block diagrams are placed and sized for easy viewing.  
Comments are used to explain block diagram functions and algorithms.  
Default values of example VIs allow the user to run the example without modification unless documented to the user (e.g. "Specify an input channel for your DAQ device")  
Example VIs comply with LabVIEW Style Checklist LabVIEW Style Checklist
[Recommended] Example VIs contain non-default icons.  
File Structure File and Folder Names for Integrating into LabVIEW
Add-on files are placed in the correct locations.  
All the supporting files should be placed either in vi.lib folder or in a custom folder other than Examples/Help folders.  
Files and folders follow a recommended company/product naming convention to ensure namespacing and avoid conflicts with other add-ons.  
Palettes and Icons LabVIEW Palette Guidelines
Add-on VI palettes are accessible from an existing logical category in the Functions palette. Any existing category may be used except "User Libraries".  
Add-on controls palettes are accessible from a custom top-level category or within the "Addons" category of the Controls palette.  
Palette organization follows palette guidelines. LabVIEW Palette Guidelines
VI and palette icons do not contain NI company or product logos.  
VI and palette icons contain a similar style or glyph to help users understand the VIs are related.  
[Recommended] VI and palette icons use glyphs or images to illustrate the VI's purpose.  
API Design Strategy for Designing an API
The API uses a consistent terminal design across all VIs (e.g. reference terminals aligned across all VIs)  
API VIs contain error terminals on the bottom left and bottom right of the connector pane.  
Left-side terminals of API VIs are used for inputs and right-side terminals are used for outputs.  
All API VIs contain VI descriptions visible through Context Help.  
[Recommended] API VI descriptions contain a link to the API's detailed help.  
Detailed Help Documentation Best Practices
The add-on includes detailed help accessible through the LabVIEW Help menu. This can be installed locally or hosted on the web. LabVIEW Help Menu Explained - Link to PDF, HTML, etc.
The detailed help outlines all hardware, software and operating system requirements. Included Utilities should be also documented for a successful operation.  
The detailed help directs users to an appropriate support channel. Free products may list "not supported".  
[Recommended] The detailed help describes how and when to use the primary VIs of the product.   
Deployment Add-on Development Guidelines
The add-on is able to be deployed to all targets with which it specifies compatibility (e.g. LabVIEW Real-Time, FPGA).  
Reusable code provided by the add-on must be able to be built into a deployable application (e.g. DLL, EXE). Exceptions or limitations must be documented in the product detailed help.  
If there are any special considerations for deployment using the add-on (such as licensing restrictions), these exceptions must be documented in the detailed help.  
Utility window placements and interactions are intuitive to the user. LabVIEW Help: Window Run-Time Position Page
Utility VIs run when opened and closes after execution. LabVIEW Help: Execution Page
Utility VIs exclude ".vi" from the window title. LabVIEW Help: Window Appearance Page
Utility VIs hide the toolbar during execution.  LabVIEW Help: Window Appearance Page
The user is provided feedback during long operations. Tools for Long-Operation Feedback in LabVIEW
[Recommended] Utilities can be launched from the LabVIEW Tools menu. VI Package Manager: Adding Examples, Help, and Tools Menu Items
The product does not include or install any malicious software.  
There are no unexpected crashes or errors when using the product.  
There are no memory or processor resource issues when using the product. LabVIEW Help: Profiling VI Execution Time and Memory Usage
The product complies with the LabVIEW Tools Network Style Guide. NI Tools Network Style Guide
The product name should comply with any NI trademarks, e.g. Product Name for LabVIEW by Company/Product Name for USRP by Company  
Custom error codes are registered with LabVIEW using an errors text file. Error Codes
The product and accompanying documentation are localized in English.  
It is clear to the user when administrator rights are required for successful use of the add-on.  
[Recommended] Custom error codes use a range assigned by the LabVIEW Tools Network team to avoid conflict with errors from other add-ons. Error Codes
