What’s New in QuickOPC 2016.2 (5.41)

Previous: What’s New in QuickOPC 5.40

Component Core Improvements (.NET)

• Added static EasyXXClient.Create() methods (behave the same as parameterless constructors).
• Ensured expandable display of all types in LINQPad.

Component Core Improvements (COM)

• Added methods _OperationEventArgs.SetState and _OperationResult.SetState (and the same to all interfaces that "inherit" from these). These methods have the same functionality as the setter for the State property. They are intended to allow easier coding with tools such as VB6, where it is was only possible to assign non-object types of values to the State property with late binding.

Packaging

• The OpcLabs.EasyOpcClassicForms and OpcLabs.EasyOpcUAForms assemblies have been merged into a single assembly, OpcLabs.EasyOpcForms. Consequently, the corresponding type libraries have also been merged in the same way.
• The NuGet packages now include LINQPad examples with them.

Examples (.NET)

• Added C# example UASimpleLogToSql: Logs OPC Unified Architecture data changes into an SQL database, using a subscription. Values of all data types are stored in a single SQL_VARIANT column.
• Added F# example project UADocExamples, and started adding examples to it. Examples taken from this project appear in the reference documentation.
• Added F# example UAConsoleApplication1: The simplest console application. Reads and displays an OPC-UA node value.
• Added examples in LINQPad.

Examples (COM)

• Added example in VB 6.0 - UAReadAndDisplayValue: The simplest form for OPC-UA. Reads and displays an OPC-UA node value.
• Added example in VBA under Excel - UAClientCertificateParameters.xls: Shows how to set the application name for the client certificate.
