Toolkit - Database Connectivity
575865

Return
Adding a "Date/Time" column using DB Tools Create Table and a MySQL database creates a column of date only
When using the DB Tools Create Table function to create a new table on a MySQL database and using a "Date/Time" column as one of the column types, the column created is only storing the date.

Workaround: Use a DB Tools Execute Query function to add a column to the table of the correct type using SQL Code after creating the table.

Reported Version: 2015  Resolved Version: N/A  Added: 08/08/2016
580060

Return
When using the SQL Server Native Client 10.0 provider, authentication occurs through Windows Integrated Security Authentication rather than through SQL Server Authentication
When the SQL Server Native Client 10.0 provider is used to connect to a database, authentication defaults to Windows Integrated Security Authentication. If an incorrect username and password combination exists in the UDL file, it is still possible for authentication to succeed through Windows Integrated Security Authentication.

Workaround: Use the "Microsoft OLE DB Provider for SQL Server" provider

Reported Version: 2015  Resolved Version: N/A  Added: 05/22/2017
618979

Return
No error is returned if an empty 2D array of variants is passed to the Database Variant to Data VI
In other cases, if an empty variant data type is passed to the Database Variant to Data VI, error 91 is returned. This error does not occur if a 2D array of variants is passed to the Database Variant to Data VI

Workaround: Check for empty arrays before the Database Variant to Data function

Reported Version: 2016  Resolved Version: N/A  Added: 05/22/2017

Reported Version: 2012  Resolved Version: N/A  Added: 08/08/2016
Toolkit - Report Generation
188911

Return
Control image alignment incorrect when "new report page" VI is used
When using Append Control Image to Report.vi, the alignment of some images are ignored when New Report Page.vi is used between appended images. This problem only exists with Office 2007. Other versions - Office 2003 and Office 2010 do not exhibit this behavior.

Workaround: Use a New Report Line.vi between appending the image and the New Page.vi

Reported Version: 2009 32-bit  Resolved Version: N/A  Added: 06/16/2010
312071

Return
Error 7 when using Report Generation Toolkit VIs in a DLL
By default Report Generation Toolkit VI's are compiled into the DLL, but can't be executed from within the DLL.

Workaround: The DLL will run correctly if you include the Report Generation toolkit lvclass dependencies in a separate support directory and specify that they are always included in a data directory.

Reported Version: 2011 32-bit  Resolved Version: N/A  Added: 03/28/2012
382455

Return
Microsoft Excel Template named cell range font size is overwritten
When appending cell data to named cell ranges from Microsoft Excel Templates, font size is always size 10pt.

Workaround: Use Excel Set Cell Font.vi to manually set the desired font for each named range.

Reported Version: 2012  Resolved Version: N/A  Added: 01/25/2013
391394

Return
Dates are Reversed by Excel Easy Table.vi on Non-US Languages
The month and day are reversed when exporting data to Excel for languages other than US-English. For example 03/02/2013 (3rd of February 2013) in LabVIEW is exported as 02/03/2013 and considered as 2nd of March 2013 by Excel.

Workaround: N/A

Reported Version: 2012  Resolved Version: N/A  Added: 08/02/2013
472835

Return
The Save Report to File.vi requires the "report file path" terminal to be wired, but is not set as a required input
The VI will return Error -41003 when running the VI if the path is not wired or empty. This requirement is enforced in the VI itself, so it will not break the run arrow.

Workaround: Wire the file path of the report to the VI.

Reported Version: 2013  Resolved Version: N/A  Added: 07/09/2014
637867

Return
LabVIEW 64-bit on Mac OS X ignores the orientation specified in the Layout Options input of the Easy Print VI Panel or Documentation VI.
N/A

Workaround: Use LabVIEW 32-bit for Mac OS X or configure the printing device instead.

Reported Version: 2015  Resolved Version: N/A  Added: 05/22/2017
642790

Return
Executables built on a machine with version 1609 of Office 365 and run on earlier versions crash when trying to save Excel sheets
In version 1609 of Office 365, the ActiveX API for interacting with Excel was changed. The SaveAs method now has a new parameter called WorkIdentity. If you run an executable that has this new parameter on the invoke node on a version before 1609, the executable will crash when attempting to save the Excel file.

If the executable is built in a version prior to 1609, it will run on later versions with no issues.

Workaround: Ensure both the build and deployment machines have the same version of Office installed, use a version earlier than 1609 to build the executable, or build the Excel_Save_Workbook VI into a Packed Project Library.

Toolkit - Unit Test Framework
120941

Return
Code Coverage analysis is not supported on LabVIEW Real-Time
The Unit Test Framework Toolkit cannot measure code coverage on real-time (RT) targets. The result will always be zero.

Workaround: N/A

Reported Version: 1.0  Resolved Version: N/A  Added: 02/06/2009
175831

Return
Cannot create a test for an XY Graph
If the VI has a XY Graph control as input or output, creating a test for this VI will fail, usually with the error "The following control name is not unique". You will get an error saying that the control name is not unique.

Workaround: N/A

Reported Version: 1.0  Resolved Version: N/A  Added: 06/23/2009
171553

Return
File load conflict after dragging multiple LV Classes to another context
You will get loading conflict for lvtest files if you open a project which has multiple LV Classes and those classes have lvtest files of the same name.
Loading any VI will also be very slow if you have this loading conflict in your project.

Workaround: Rename the lvtest files to different names. Or remove those lvtest files from the project and re-add them.

Reported Version: 2009  Resolved Version: N/A  Added: 08/05/2009
420795

Return
When creating a custom LV project template with the Unit Test Framework .lvtest file, the new project will overwrite the original template when saving instead of creating a new instance with new files.

Workaround: N/A

Reported Version: 2012  Resolved Version: N/A  Added: 05/07/2014
466818

Return
Error 1527 will occur when running the example "Programmatically Run Tests from Projects.vi" referencing the example project "LV Class.lvproj."

Workaround: 1. Open LV Class.lvproj
2. Open by double clicking in Windows Explorer "Programmatically Run Tests from Projects.vi" (Now the VI will be in the LV Class.lvproj LabVIEW instance)
3. Modify "Programmatically Run Tests from Projects.vi" to run LV Class.lvproj
4. Run the VI

Reported Version: 2013  Resolved Version: N/A  Added: 05/07/2014
475037

LabVIEW: Type Mismatch: Object cannot be cast into the specified type.

Workaround: If possible, do not have a control connected to the VI's terminal and inside a tab control.

Reported Version: 2010  Resolved Version: N/A  Added: 07/09/2014
555738

Return
In certain cases, Unit Test Framework cannot detect a LV Class object inside a Packed Project Library when block diagrams are removed.

Workaround: Set the block diagram of the VI calling the LV Class to not be removed in the Packed Project Library's build specification.

Reported Version: 2014  Resolved Version: N/A  Added: 03/09/2016
683963

Return
The Unit Test Framework may remove trailing zeros from fixed point numbers in the reports it generates.
