System Requirements


The development computer must meet the following system requirements to run the NI Vision Development Module:

How to Activate the NI Vision License


When you run an NI Vision application for the first time, it prompts you to activate a license for the product. If you do not activate a valid license, the NI Vision application will run in Evaluation Mode and continue to prompt you to activate a license on each subsequent launch.
Complete the following steps to activate the NI Vision license through an Internet connection.

• Run the product you want to license.

• Click Yes when prompted to interactively activate your product.

• Ensure that Automatically activate through a secure Internet connection is selected, and click Next.

• Enter the product serial number, and click Next.

• Enter your registration information, and click Next.
  

Tip: Enter your email address to receive a copy of your activation code for your records.
Deploying Vision Applications


Deployment refers to developing an application so that it can be distributed, or deployed, on a different computer than the one on which the application was developed. The NI Vision Development Module provides everything you need to deploy custom NI Vision applications to target computers. The NI Vision Development Module provides the following options:

• The ability to create NI Vision Run-Time Engine installers, which integrate with the LabVIEW Application Builder, applications built in LabWindows/CVI, or a custom installer.

• The ability to install the NI Vision Run-Time Engine directly from the Vision Development Module CD.

• One NI Vision Run-Time License, which allows you to install a custom application on a single machine.
  

You can install a number of different versions of the NI Vision Run-Time Engine. The NI Vision Development Module installer also contains the run-time engine installer for NI Vision. Visit the Drivers and Updates section of ni.com to download software upgrades for NI Vision and the NI Vision Run-Time installers.
Purchasing NI Vision Deployment Licenses


You must purchase an NI Vision Run-Time License (part number 778044-03) for each target machine onto which you want to install your custom NI Vision application, even if you install the NI Vision Run-Time Engine directly from the NI Vision Development Module CD. The NI Vision Development Module CD ships with one run-time license. Contact a National Instruments sales representative or visit ni.com to purchase additional run-time licenses.
Note: Additional NI Vision Run-Time Licenses do not include a CD. To install additional licenses, use the original NI Vision Development Module CD and the serial number provided by National Instruments.
Using the NI Vision Run-Time Engine


You can call the NI Vision Run-Time Engine installer from the application installer. If you create the application installer with the LabVIEW Application Builder or with LabWindows/CVI, you can direct the installer to call the NI Vision Run-Time Engine installer.
Refer to the LabVIEW Help for more information about the LabVIEW Application Builder. Refer to the NI LabWindows/CVI Help for more information about building and distributing LabWindows/CVI applications.
You can also direct a custom application installer to call the NI Vision Run-Time Engine installer. Refer to the documentation that came with the installer software to learn how to call executables from the custom installer. If you are using a custom installer, call the NI Vision Run-Time Engine installer at the end of the installation procedure because the installer may require the system to be restarted.
To use the NI Vision Run-Time Engine installer, you must add /qn as a command line argument to the run-time engine installer. For example, enter <Vision>Run-Time Engineision86rte.exe /qn to run the NI Vision Run-Time Engine installer, where <Vision> is the location to which NI Vision is installed.
Distributing LabVIEW Applications


The NI Vision Run-Time Engine installer does not install LabVIEW VIs. If you use the LabVIEW Application Builder to create an application (EXE) or dynamic link library (DLL), the Application Builder automatically includes the VIs used by the application. If you distribute a VI, you must include all subVIs that comprise the top-level VI. You must include the appropriate LabVIEW Run-Time Engine as part of the installation.
Refer to the LabVIEW Help for more information about viewing the hierarchy of VIs and for more information about using the LabVIEW Run-Time Engine.
Distributing LabWindows/CVI Applications


In addition to including the NI Vision Run-Time Engine with the installer, you must include the appropriate LabWindows/CVI Run-Time Engine. Refer to the NI LabWindows/CVI Help for more information about creating an executable, creating a dynamic link library, and distributing applications.
Using NI Vision with Microsoft Visual Studio .NET 2003


NI Vision supports interoperability between the Vision ActiveX control and Microsoft Visual Studio .NET 2003. NI Vision installs the following Interop Assemblies that allow .NET languages to correctly communicate with the ActiveX controls:

• NationalInstruments.AxCWIMAQControlsLib.Interop.dll—cwimaq.ocx

• NationalInstruments.AxCWIMAQHelpButton.Interop.dll—CWIMAQHlpBtn.ocx

• NationalInstruments.AxCWMV.Interop.dll—cwmv.ocx

• NationalInstruments.AxNIOCRLib.Interop.dll—niocr.ocx
  

You can find these assemblies in the <Vision>dotNETAssembliesCurrent directory. The assemblies installed by NI Vision correctly wrap several methods that generate errors if you call the methods using the assemblies generated by Visual Studio .NET. For information about the properties, methods, and events available with these assemblies, refer to the NI Vision for Visual Basic Reference Help and the NI Vision for Visual Basic User Manual.
Creating a New .NET Application Using NI Vision


You must first add the NI Vision controls to your toolbox when creating a new application. Complete the following steps to add the NI Vision controls to the Microsoft Visual Studio .NET 2003 Toolbox:

• In Visual Studio .NET, either create a new application or open an existing one.

• Open a form in Design View.

• Select View»Toolbox.

• Select the category in which you want the NI Vision controls to appear, such as General, Components, and so on.

• Select Tools»Add/Remove Toolbox Items.

• In the .NET Framework Components tab, select the controls you want to add to your application. Choose from CWIMAQ, CWIMAQVision, CWIMAQViewer, CWMachineVision, and NIOCR.
  

When the controls are in the toolbox, you can add them to your forms by clicking the tool and drawing an area on the form. References to the NI Vision Interop Assemblies are automatically added to your project.
Converting an Existing Microsoft Visual Basic 6.0 Application


Microsoft's automatic upgrade engine often generates its own Interop assemblies rather than referencing the official NI Vision Interop assemblies. When this happens, your project will have two references for every NI Vision assembly needed. Complete the following steps to correctly reference the NI Vision Interop assemblies:

• In Visual Studio .NET, select Edit»Find and Replace»Replace in Files. Replace the following with NationalInstruments.CWIMAQ Controls:
  

• AxCWIMAQControlsLib

• AxCWIMAQHelpButtonLib

• AxCWMVLib

• AxNIOCRLib
  

• Select View»Solution Explorer.

• Expand the Project References.

• Remove the following references if they are present:
  

• AxCWIMAQControlsLib

• AxCWIMAQHelpButton

• AxCWMV

• AxNIOCRLib
  

Viewing the NI Vision Examples


The NI Vision examples for Microsoft Visual Studio .NET 2003 are converted from the NI Vision for Visual Basic examples. The .NET examples are written in Visual Basic .NET and demonstrate use of the NI Vision Interop Assemblies. The examples are located in the <Vision>ExamplesMSVB.NET directory, and the images for the examples are located in the <Vision>ExamplesImages directory.
Known Issues

• Upgrading an RT desktop formatted with a LabVIEW Real-Time 8.2.1 boot disk to LabVIEW Real-Time 8.6, and installing any NI Vision 8.6 Development Module components to the RT desktop, the RT desktop fails to complete the boot-up process. The RT desktop hangs before the Welcome to LabVIEW 8.6 message. To fix the hang, format the RT desktop with a LabVIEW Real-Time 8.6 utility USB drive. Install LabVIEW Real-Time 8.6 and the NI Vision 8.6 Development Module.

• AVI functionality requires Microsoft DirectX 8.1 or later.

• On Windows XP computers with Service Pack 2 installed, NI Vision does not support reading AVI files located in the Local Settings folder, or any subfolders of this folder, when the AVI file uses any of the following compression filters:
  Copying the AVI file to another folder resolves this problem.

• Indeo® Video 5.10 Compression Filter

• Intel Indeo® Video R3.2

• Intel Indeo® Video 4.5

• Indeo® Video 5.10
  

• Viewing the online help files requires Microsoft Internet Explorer 5 or later.

• Using NI Vision with LabWindows/CVI on a machine that does not support the MMX instruction set may cause an Illegal Operation exception to occur within the LabWindows/CVI environment. This error occurs when DirectX checks for the availability of the MMX instruction set on the machine.

• The Visual Basic .NET examples may display the UI controls with incorrect size and location settings if you use a computer with a DPI display setting other than 96 DPI. 96 DPI is the default setting for most Windows operating systems.
