Measurement Studio 8.1.2 for Visual Studio .NET 2003 Readme

Measurement Studio 8.1.2 includes separate, parallel sets of class libraries, integration features, and support documentation for developing with Visual Studio .NET 2003 and Visual Studio 2005.

This readme documents Measurement Studio support for Visual Studio .NET 2003. Refer to the readme on the Measurement Studio Support for Visual Studio 6.0 CD for information about Visual Studio 6.0 support. You can install support for both Visual Studio .NET 2003 and support for Visual Studio 6.0 on the same machine. However, you must install the support to separate directories.

This section describes new features that have been introduced in Measurement Studio since version 8.1.1.

Legend Control Scrollbars

For more information, refer to Using the Measurement Studio Windows Forms Legend .NET Control or Using the Measurement Studio Web Forms Legend .NET Control in the NI Measurement Studio Help.

WYSIWYG Editing of Labels with Engineering Formatting in Measurement Studio User Interface Controls

This feature is enabled by default for new Measurement Studio controls you add to your project. You can enable this feature for existing Measurement Studio controls in your project by checking the WYSIWYG Editing check box in the Numeric Format Mode Editor dialog box. You access the Numeric Format Mode Editor dialog box for the numeric edit control and the numeric edit array control by selecting the FormatMode property on the Property Pages for the control. You access the Numeric Format Mode Editor dialog box for the numeric pointer controls and the axes of the graph controls by selecting the EditRangeNumericFormatMode property in the Property Pages for the control.

Programmatic Parsing of Strings with Engineering Formatting

Measurement Studio support for Visual Studio 6.0 will now require you to run only one installer instead of an initial installation and an updater installer. Measurement Studio's Visual Studio 6.0 support also includes support for Microsoft Windows Vista.

Measurement Studio 8.1.2 includes analysis code snippets in the documentation that can be copied and pasted into an application and used immediately. The following classes include new example code snippets:

CurveFit
ArrayOperations
Digital Filters—Bessel, Butterworth, and Chebyshev
Statistics

For more information about what's new in Measurement Studio 8.1.2, refer to the What's New in Measurement Studio section of the NI Measurement Studio Help.

Installing Measurement Studio 8.1.2

To use Measurement Studio, your computer must have the following:

Microsoft Windows XP/2000
Microsoft .NET Framework 1.1 (required only for the Measurement Studio .NET class libraries)
Standard, Professional, Enterprise Developer, Enterprise Architect, or Academic edition of Microsoft Visual Studio .NET 2003
Intel Pentium III class processor, 1 GHz or higher
Video display—1024 × 768, 256 colors (16-bit color recommended for user interface controls)
Minimum of 256 MB of RAM (512 MB or higher recommended)
Minimum of 405 MB of free hard disk space
Microsoft-compatible mouse
Microsoft Internet Explorer 6.0 or later

Installation Instructions

National Instruments recommends that you exit all programs before running the Measurement Studio installer. Applications that run in the background, such as virus scanning utilities, might cause the installer to take longer than average to complete.

National Instruments recommends that you install the complete Measurement Studio program. If you perform a custom installation and do not install all the Measurement Studio features, you can run the installation program again later to install additional features.

Note The option to browse for an installation location is valid only if you have not already installed any Measurement Studio features for the version of Visual Studio or the .NET Framework that you are installing. If you have any Measurement Studio features installed, then Measurement Studio installs to the same root directory to which you installed other Measurement Studio features.

Installing the Current Version of Measurement Studio over Previous Versions of Measurement Studio

If you install a newer version of Measurement Studio on a machine that has a prior version of Measurement Studio installed, the newer version installer replaces the prior version functionality, including class libraries. However, the prior version assemblies remain in the global assembly cache (GAC); therefore, applications that reference the prior version continue to use the prior version .NET assemblies.

Note This does not apply to NationalInstruments.Common.dll. NationalInstruments.Common.dll uses a publisher policy file to redirect applications to always use the newest version of NationalInstruments.Common.dll installed on the system, for each version of the .NET Framework. NationalInstruments.Common.dll is backward-compatible.

For assistance in getting started with Measurement Studio 8.1.2, refer to the Measurement Studio Overview and the Getting Started with the Measurement Studio Class Libraries topics in the NI Measurement Studio Help or refer to the Measurement Studio User Manual and the Measurement Studio Release Notes. You can launch the NI Measurement Studio Help in the following ways:

From the Windows Start menu, select Start»All Programs»National Instruments»Measurement Studio for Visual Studio .NET 2003»Measurement Studio Documentation. The help launches in a stand-alone help viewer.
From Visual Studio, select Help»Contents to view the Visual Studio table of contents. The NI Measurement Studio Help is listed in the table of contents.
From Visual Studio, select Measurement Studio»NI Measurement Studio Help. The help launches within the application.

To get started creating a Measurement Studio project using class library and application templates, open Visual Studio and select File»New» Project to launch the New Project dialog box. In the Project Types pane, expand the Measurement Studio Projects folder and select the Projects folder for the language you want to create the program in. Then, in the Templates pane, select the type of project you want to create.

For information about deploying applications built with Measurement Studio 8.1.2, refer to Deploying Measurement Studio Applications in the NI Measurement Studio Help.

Note Measurement Studio support for Visual Studio .NET 2003 does not support redistributing applications to Windows 95/98/Me/NT 4.0.

Bug Fixes in Measurement Studio 8.1.2

For a complete list of incompatibilities in Measurement Studio with previous versions of Measurement Studio and otherwise supported features, including a list of obsoleted members and members that have been changed to sealed override or non-virtual, refer to the Measurement Studio Incompatibilities topic in the NI Measurement Studio Help.

4CN6TVBU: In Measurement Studio 8.1.2 and later, when you add a new annotation programmatically, the control assigns the annotation a unique name, in the format of Annotation-n, where n is a number. In previous versions of Measurement Studio, the control finds the lowest n that yields a name that is not the same as the name of another annotation in the collection. In Measurement Studio 8.1.2 and later, the control finds the lowest n that is greater than or equal to the number of items in the collection.
For example, consider the scenario where you have a collection that has two annotations, named Annotation-2 and Annotation-3, and you add an annotation. In previous versions of Measurement Studio, the name of the added annotation is Annotation-1. In Measurement Studio 8.1.2 and later, the name of the added annotation is Annotation-4.

3NIAKPK5: The Measurement Studio Instrument Driver Wizard produces non-compiling Visual Basic code for P/Invoke methods that have a void return type.

.NET Class Libraries Known Issues

4CLI5R3Q: Upgrading to Measurement Studio 8.1.2 may cause the Analysis library to produce numerical differences in floating point results and different results for exceptional inputs, such as positive or negative infinity and NaN. These differences may occur because the underlying C Analysis library has been recompiled in Measurement Studio 8.1.2 to take advantage of new processors and operating systems.
3OU62J9Q: You cannot use Measurement Studio class libraries in 64-bit applications. You can, however, use Measurement Studio class libraries in 32-bit applications and run those applications on Vista x64, provided that all drivers you use in the applications support Vista x64.
2TSHI79Q: National Instruments has designed the VisaNS API as a custom, optimized .NET interface to NI-VISA.
2Q9A0503: Under some circumstances, plots with data that extend outside the plot area are clipped incorrectly. As a result, part of the plot is not drawn. Microsoft has confirmed that this is a problem with clipping in the .NET Framework.
3AEERJQ6: If you copy and paste Measurement Studio user interface .NET controls from one instance of Visual Studio .NET 2003 to another instance of Visual Studio .NET 2003, an unlicensed exception is thrown and the second instance of Visual Studio .NET 2003 shuts down in thirty seconds. You can copy and paste Measurement Studio UI controls from one project to another within the same instance of Visual Studio .NET 2003 without receiving the unlicensed exception.
39R92Q9Q: If your project references NationalInstruments.UI.WindowsForms, but does not reference the assemblies it depends on, there are circumstances in which the Windows Forms Designer will stop drawing the controls. This occurs when the Windows Forms Designer re-parses its generated code and is unable to resolve references to types that are in the assemblies that NationalInstruments.UI.WindowsForms depends on. To fix this problem, add project references to NationalInstruments.UI and NationalInstruments.Common. Measurement Studio does this for you automatically, so you will see this issue only if you disable Measurement Studio integration features in Visual Studio.

Visual C++ Class Libraries Known Issues

3OU62J9Q: You cannot use Measurement Studio class libraries in 64-bit applications. You can, however, use Measurement Studio class libraries in 32-bit applications and run those applications on Vista x64, provided that all drivers you use in the applications support Vista x64.
3Q2AK93P: The Analysis library now calls the LoadLibrary function. Under most circumstances, it is unsafe to call LoadLibrary inside DllMain. Therefore, avoid calling any analysis functions inside DllMain.
2VJIONX0: If you have created a Visual C++ Console Application and are linking statically to MFC, you may encounter LNK2005 and LNK1169 errors. This problem happens when MFC static libraries and CRT static libraries link in the wrong order. To correct this problem, ensure that the #include <afx.h> statement is the first include statement in the generated stdafx.h header file. For more information, refer to Microsoft Knowledge Base Article 148652.
2ZEE6I9Q: In Visual C++, the Measurement Studio 8.1.2 implementation of windowless controls is not compatible with the MFC ActiveX control container. Measurement Studio controls do not paint correctly when you set the Windowless property to true. You can work around this issue using a helper class to implement the appropriate dialog, SDI, or MDI function. For more information, refer to National Instruments KnowledgeBase Article 2ZFF2AXL.
3LI9DC56: In Visual C++, if you have Measurement Studio windowless controls and any windowed controls together on an MFC dialog box, tabbing through the dialog box skips all windowless controls.
2YFFDK03: In Visual C++, the property browser does not handle ActiveX controls correctly. National Instruments recommends you use the property pages to modify Measurement Studio controls in the Visual C++ resource editor. To access the property pages, right-click a Measurement Studio Visual C++ control and select Properties.
2HR8MFYQ: Measurement Studio Visual C++ controls do not support being hosted in HTML dialogs. HTML dialogs use the CDHtmlDialog base class.
2IC7BO63: In Visual C++, the wrappers that Visual C++ generates for the Measurement Studio ActiveX controls are incomplete. Visual C++ generates wrappers only for the top-level objects in the controls. This causes some Visual C++ generated wrappers to produce compile errors. Refer to National Instruments KnowledgeBase Article 2IECTLXL for more information and suggested workarounds.
2HLFT4LT: LabVIEW Real-Time DLLs you create with the Measurement Studio LabVIEW Real-Time Interface class library work only with the LabVIEW RT software 6.0 and later.
2ZGK8P9Q: LabVIEW Real-Time 6.1 and later does not support the 7030 LabVIEW Real-Time Series processor board. You can continue to use this board with the Measurement Studio LabVIEW Real-Time Interface class library if you are using a version of LabVIEW Real-Time prior to version 6.1.
2HLFT4LT: If you download a VI to a LabVIEW RT Series processor board that calls into a DLL that uses the Measurement Studio LabVIEW RT class library, you must reference MStudio Shared Memory.vi from your VI. The LvRTDLL example, located at Program FilesNational Instruments<MeasurementStudio>VCNETExamplesLVRealTimeLvRTDLL , demonstrates how to do this operation.

Documentation Known Issues

44BCUIHW: Using Measurement Studio Help for Visual Studio 2003 and browsing to some sub-elements while logged in as a limited user in Windows Vista causes an install dialog to appear. This issue is fixed by allowing MSDN to repair itself when prompted.
40SF8MWN: Measurement Studio Visual C++ properties that are defined by get and set methods do not show help in the Object Browser. Refer to the NI Measurement Studio Help to view the help for these properties.
451EGFBK: Windows Vista does not support use of help files with a .hlp file extension, including What's This? help. If you want to view .hlp files, you must download and install the WinHlp.exe program from the Microsoft Download Center.

What's New in Measurement Studio 8.1.2

You can use the Measurement Studio legend control scrollbar to scroll through the legend items at run time instead of having a fixed size for the control. This enables you to conserve valuable space in your application while still representing all the items necessary for a useful legend.

Prior versions of Measurement Studio only support editing engineering formatted values at run time as basic numeric formatted strings. In Measurement Studio 8.1.2, you can edit engineering formatted values at run time as engineering formatted strings or as basic numeric formatted strings. Engineering formatted values are numeric values formatted with engineering notation and International System of Units (SI) prefixes and symbols. You can edit engineering formatted values for the Windows Forms and Web Forms numeric edit control and the Windows Forms numeric edit array control. You can edit engineering formatted range for the Windows Forms numeric pointer controls and the Windows Forms and Web Forms scatter, waveform, and complex graph axes.

You can use the NationalInstruments.EngineeringFormatInfo.TryParse method or the NationalInstruments.EngineeringFormatInfo.Parse method to convert the engineering string representation of a number to its double-precision floating-point number equivalent based on the format you specify. You use TryParse or Parse to parse an engineering string representation of a value, such as a formatted string returned by NationalInstruments.EngineeringFormatInfo.Format, to obtain the actual value.

Network Variable Library Enhancements

Logos is the underlying technology of the NI-Publish Subscribe Protocol (psp:), a National Instruments proprietary protocol for inter-process communication. Network variables in Measurement Studio 8.1.2, LabWindows/CVI 8.5, and LabVIEW 8.5 and later use a new implementation of Logos called LogosXT. You can use LogosXT to increase the speed of network variable data transfer—LogosXT is approximately 3.5 times faster when all host machines are running LogosXT instead of Logos. LogosXT is automatically installed when you install Measurement Studio 8.1.2.

Updated Visual Studio 6.0 Support

As you work with Measurement Studio Support for Visual Studio 6.0, you might need to consult additional resources. For detailed Measurement Studio help, including function reference and in-depth documentation on developing with Measurement Studio, refer to the Measurement Studio Reference and Measurement Studio Reference Addendum.

Select the top-level category in the Categories pane to access Visual Studio templates.
42BE2QHW: If you install Visual Studio Service Pack 1 and create a new Web Application Project by selecting File»New» Project, you have to use the Add/Remove Class Libraries Wizard or add the references manually before dropping a control; otherwise, the control will load incompletely. Select Measurement Studio»Add/Remove Class Libraries to use the wizard.
3W2CC3HW: When you use the DAQ Assistant within Visual Studio, Visual Studio will occasionally get into a state where it reports the following error: Error HRESULT E_FAIL has returned from a call to a COM component. Restart Visual Studio to fix this issue.
3UE8MH9Q: Under some circumstances, when using Measurement Studio help within Visual Studio, an Internet Explorer security warning displays in the help window. This is expected behavior, and it is okay to view the active content. To remove the warning, right-click the information bar and select Allow Blocked Content. Click Yes in the Security Warning dialog box to allow the blocked content.
3PJGFO99: When upgrading from an Instrument I/O Assistant 1.x or 2.0 task to an Instrument I/O Assistant 2.1 and higher task, the lifetime of the instrument session now corresponds to the lifetime of the task object instead of to a new session created each time the Run method is called. You might need to update your code to dispose of the task when you finish using the task in your application.
3VME01FF: If you have a source file open and no project loaded, you cannot use the Parameter Assistant to insert text. Load a project to use the Parameter Assistant.
2PHBA1LT: When the Windows Forms Designer and a source code window are both open, and the Windows Forms Designer is active, the Parameter Assistant does not restrict code from being inserted into the source file. Instead, code is inserted into the source file at the last cursor location, which might have been changed by the Windows Forms Designer.
3NIAKPK5: The Measurement Studio Instrument Driver Wizard produces non-compiling Visual Basic code for P/Invoke methods that have a void return type.

.NET Class Libraries Known Issues

4CLI5R3Q: Upgrading to Measurement Studio 8.1.2 may cause the Analysis library to produce numerical differences in floating point results and different results for exceptional inputs, such as positive or negative infinity and NaN. These differences may occur because the underlying C Analysis library has been recompiled in Measurement Studio 8.1.2 to take advantage of new processors and operating systems.
4B89AJ00: Network variable performance decreases when machines hosting the reader, writer, and variables are mixed between Logos and LogosXT. Logos is the National Instruments proprietary protocol for inter-process communication that is used by NI-Publish Subscribe Protocol (psp:). Performance is especially degraded when the writer and network variable host use LogosXT and the reader that attempts to read the network variable uses Logos. This issue occurs for all reader classes.For optimum performance, National Instruments recommends that all machines accessing network variables, including the machine that hosts the variable, should use LogosXT. If using LogosXT on all machines is not possible, you should disable LogosXT. You disable LogosXT by adding a DWORD value named DisablePSPXT to the registry key HKEY_LOCAL_MACHINESOFTWARENational InstrumentsLogosXT and setting its value to 1. If you must use a mix of Logos versions, you can reduce the performance loss by using Variable Manager. Use Variable Manager to configure a sufficiently large server-side buffer for the network variable.
47S9T2WN: When you drop a Measurement Studio ASP.NET Web Forms control on a Web page, without having a reference to the NationalInstruments.UI.WebForms assembly in your Web project, wait a few seconds before building your project to allow Visual Studio and Measurement Studio integrated tools to properly update the web.config file. If you build the project before it is properly updated, then you might get build errors. In this case, remove the dropped control and re-drop it in your project. Alternatively, always add a reference to the NationalInstruments.UI.WebForms assembly to your Web project before you use a Measurement Studio ASP.NET Web Forms control in it.
3Y0AE1HW: The network variable class library deadlocks if you are stepping through code in a network variable class library event handler and you are watching any of the following properties in the Debugger Watch Window:
When the Debugger evaluates properties in the Watch Window, it freezes all other threads except the currently executing thread. When the network variable thread is frozen, the network variable class library deadlocks. To work around this issue, do not add the properties listed above to the Watch Window when stepping through network variable event handler code.

ConnectionStatus,
NetworkVariableBufferedSubscriber.ItemCapacity,
NetworkVariableBufferedSubscriber.ItemCount,
NetworkVariableBufferedWriter.ItemCapacity, or
NetworkVariableBufferedWriter.ItemCount.

40HE16WN: Adding a Web Forms NetworkVariableDataSource control from the Form View control smart tag does not work. To add a NetworkVariableDataSource control to the page, drag and drop it from the Toolbox. Select View»Toolbox and expand the Measurement Studio group. Drag and drop the NetworkVariableDataSource control onto the page.
3X4EPFQ6: In Measurement Studio Visual C++/CLI projects, when you drop a Measurement Studio control on a form, Visual Studio adds the Measurement Studio assemblies from the GAC. If you select Measurement Studio>>Refresh Project License File, the contents of the .licx file are cleared. Without the proper contents in the .licx file, running your project results in unlicensed exceptions. To refresh the .licx file, select Measurement Studio>>View .NET Class Library Wizard. In the Measurement Studio .NET Class Library Wizard dialog box, deselect the Measurement Studio libraries and close the dialog box. Run the Measurement Studio .NET Class Library Wizard again and select the Measurement Studio libraries.
3SIA223P: When you build a project in Visual Studio 2005 that references the NationalInstruments.Common assembly, you might receive warning MSB3247: Found conflicts between different versions of the same dependent assembly.This warning occurs when the version of NationalInstruments.Common installed on your machine is newer than the version that the project originally referenced. The NationalInstruments.Common assembly is designed to be backward compatible with older versions. The NationalInstruments.Common assembly uses publisher policy to redirect references from older versions to newer versions. Therefore, it is safe to disregard this warning and use the latest version of the NationalInstruments.Common assembly.
If you double-click the warning in the Error List in Visual Studio 2005, Visual Studio provides you the option to generate a binding redirect in your app.config file. If you generate a binding redirect, the warning is no longer generated when you build the project. However, if the NationalInstruments.Common assembly is subsequently updated on the machine, building the referencing project will result in a build error. To fix the build error, you must update the binding redirect entry in app.config.
For more information about Measurement Studio class library versioning, refer to the Measurement Studio .NET Class Library Versioning and Redistribution topic in the NI Measurement Studio Help. For more information on general .NET Framework assembly binding, redirecting, and publisher policy, refer to the Redirecting Assembly Versions topic in the .NET Framework Developer's Guide.
3TOA9UWN: When working with Measurement Studio assemblies in Visual Basic .NET applications, Visual Studio 2005 sometimes displays a dialog with the following information: "Microsoft (R) Visual Basic Compiler has encountered a problem and needs to close. We are sorry for the inconvenience." This dialog closes Visual Studio 2005 and causes you to lose any unsaved work. Microsoft has confirmed that this is a Visual Basic .NET compiler issue. To work around this issue, close and restart Visual Studio 2005.
3OU62J9Q: You cannot use Measurement Studio class libraries in 64-bit applications. You can, however, use Measurement Studio class libraries in 32-bit applications and run those applications on Vista x64, provided that all drivers you use in the applications support Vista x64.
2TSHI79Q: National Instruments has designed the VisaNS API as a custom, optimized .NET interface to NI-VISA.
2Q9A0503: Under some circumstances, plots with data that extend outside the plot area are clipped incorrectly. As a result, part of the plot is not drawn. Microsoft has confirmed that this is a problem with clipping in the .NET Framework.
3LIEB2X0: For ASP.NET Web Forms controls, the design-time previews for the following controls are not displayed in the Designer if the control is in a table, template, or user control on the page: complex graph, digital waveform graph, gauge, knob, LED, legend, meter, scatter graph, slide, switch, tank, thermometer, and waveform graph.
3O286BWN: If you access an ASP.NET Web page in Mozilla Firefox or Opera using the ASP.NET Web Development Server, you receive a login error. In Firefox, a dialog box displays asking you to login. If you attempt to login, you receive an access forbidden error. In Opera, you receive this error: "The server requested a login authentication method that is not supported." These errors occur because NTLM authentication is selected in the Property pages. You can modify this setting.

Right-click on the project and select Property Pages.
Select Start Options.
Deselect NTLM Authentication in the Server section.

39R92Q9Q: If your project references NationalInstruments.UI.WindowsForms, but does not reference the assemblies it depends on, there are circumstances in which the Windows Forms Designer will stop drawing the controls. This occurs when the Windows Forms Designer re-parses its generated code and is unable to resolve references to types that are in the assemblies that NationalInstruments.UI.WindowsForms depends on. To fix this problem, add project references to NationalInstruments.UI and NationalInstruments.Common. Measurement Studio does this for you automatically, so you will see this issue only if you disable Measurement Studio integration features in Visual Studio.

Visual C++ Class Libraries Known Issues

3OU62J9Q: You cannot use Measurement Studio class libraries in 64-bit applications. You can, however, use Measurement Studio class libraries in 32-bit applications and run those applications on Vista x64, provided that all drivers you use in the applications support Vista x64.
3Q2AK93P: The Analysis library now calls the LoadLibrary function. Under most circumstances, it is unsafe to call LoadLibrary inside DllMain. Therefore, avoid calling any analysis functions inside DllMain.
2VJIONX0: If you have created a Visual C++ Console Application and are linking statically to MFC, you may encounter LNK2005 and LNK1169 errors. This problem happens when MFC static libraries and CRT static libraries link in the wrong order. To correct this problem, ensure that the #include <afx.h> statement is the first include statement in the generated stdafx.h header file. For more information, refer to Microsoft Knowledge Base Article 148652.
2ZEE6I9Q: In Visual C++, the Measurement Studio 8.1.2 implementation of windowless controls is not compatible with the MFC ActiveX control container. Measurement Studio controls do not paint correctly when you set the Windowless property to true. You can work around this issue using a helper class to implement the appropriate dialog, SDI, or MDI function. For more information, refer to National Instruments KnowledgeBase Article 2ZFF2AXL.
3LI9DC56: In Visual C++, if you have Measurement Studio windowless controls and any windowed controls together on an MFC dialog box, tabbing through the dialog box skips all windowless controls.
2YFFDK03: In Visual C++, the property browser does not handle ActiveX controls correctly. National Instruments recommends you use the property pages to modify Measurement Studio controls in the Visual C++ resource editor. To access the property pages, right-click a Measurement Studio Visual C++ control and select Properties.
2HR8MFYQ: Measurement Studio Visual C++ controls do not support being hosted in HTML dialogs. HTML dialogs use the CDHtmlDialog base class.
2IC7BO63: In Visual C++, the wrappers that Visual C++ generates for the Measurement Studio ActiveX controls are incomplete. Visual C++ generates wrappers only for the top-level objects in the controls. This causes some Visual C++ generated wrappers to produce compile errors. Refer to National Instruments KnowledgeBase Article 2IECTLXL for more information and suggested workarounds.
