If you copy and paste dynamically filtered help content into a text editor, such as Microsoft Word, you may see content that applies to components not installed on your machine.
At page load time, Measurement Studio dynamically filters documentation based on the components or package you have installed. If you copy and paste dynamically filtered help content into a text editor, such as Microsoft Word, you may see content that applies to components not installed on your machine.

Return
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.

Workaround: 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_MACHINE\SOFTWARE\National Instruments\LogosXT 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.

Return
Creating network variables causes a small memory leak
Creating a network variable using the ServerVariable.Create or ServerVariableInfo.Create methods results in a memory leak of approximately 50 bytes per variable that is created.

Workaround: Consider using implicitly created network variables if you are creating and deleting numerous variables over a long period of time.

Return
In some circumstances, the network variable class library deadlocks if you are stepping through code in a network variable class library event handler.
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:
  •  ConnectionStatus,
  •  NetworkVariableBufferedSubscriber.ItemCapacity,
  • NetworkVariableBufferedSubscriber.ItemCount,
  •  NetworkVariableBufferedWriter.ItemCapacity, or
  • NetworkVariableBufferedWriter.ItemCount.
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.

Workaround: To work around this issue, do not add the properties listed above to the Watch Window when stepping through network variable event handler code.

Return
In some instances, running your Visual C++/CLI project results in unlicensed exceptions.
In Visual C++/CLI projects, when you drop a Measurement Studio control on a form, Visual Studio references 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.

Workaround: 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.

133413

Return
The Windows Forms Designer presents an error page stating that parts cannot be found.
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 presents an error page stating that parts cannot be found. 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.

Workaround: To fix this problem, add project references to NationalInstruments.UI and NationalInstruments.Common. Measurement Studio does this for you automatically, so you see this issue only if you disable Measurement Studio integration features in Visual Studio.

If you call Graph.ToImage(Size), the DrawGridLines method incorrectly draws the graph axes.
If the destination size is not the same as the graph image size, the axes do not scale correctly.

Workaround: Use the overload of ToImage that does not take any parameters. This overload creates an image the same size as the graph. You can scale this image to your required size. However, rescaling the image can cause pixelation.

Measurement Studio adds National Instruments references to the web.config file of non-Measurement Studio projects.

Workaround: Complete either of the following workarounds to fix this issue:
  • Remove the Measurement Studio controls from the Toolbox when you are working within a WebForms project.
  • For both Visual Studio 2005 and Visual Studio 2008, you must make the following edit in the Visual Studio 2005 registry location. This is due to a bug in the Visual Studio 2008 integration code. Refer to How to Modify the Windows Registry for information on how to work safely within the Windows Registry.

Return
A memory leak exists in WebForms.NetworkVariableDataSource when Dispose is not called before the host page is unloaded.
The internal implementation of WebForms.NetworkVariableDataSource requires that Dispose be called to clean up internal resources which manage the low-level connections to network variables. This issue does not occur in the typical case, where the data source is hosted on a Web Form because the form calls Dispose on its children. This issue can occur if the program dynamically creates data sources and/or attempts to cache data sources across post backs (e.g., in session state).

Workaround: If you dynamically create data source controls, call Dispose on them before the post back completes. This can be done, for example, in the Page_Unload event of the page that contains the controls that the data source binds to. Do not cache instances of NetworkVariableDataSource across post back.

Appending data and adding properties to a TDMS file in a specific sequence can corrupt the file data.
The following specific sequence of calls causes the data in a TDMS file to be corrupted:
for(int i = 0; i < 3; i++)
{
    channel1.AppendData<double>(data, TdmsSaveFile.SaveFile);
    channel2.AppendData<double>(data, TdmsSaveFile.SaveFile);
    channel1.AddProperty("Test", TdmsPropertyDataType.Int32, samples);
    file.Save();
}

Note that the following conditions must be met for this behavior to occur:
  1. You must be writing to two channels.
  2. The value passed for the saveFile parameter in TDMS_AppendDataValues must be 1 for both channels.
  3. The TDMS_SetChannelProperty call must come after the two writes.
  4. TDMS_SaveFile must be called after TDMS_SetChannelProperty.
  5. The loop must have at least 3 iterations.
If 0 is passed for the saveFile parameter for either of the TDMS_AppendDataValues calls, or the TDMS_SetChannelProperty call is done before either of the data writes, the data is not corrupted.
