Thanks!!! IT WAS THE BUG THATCAUSED THE PROBLEM! Thanks however for the prompt reply and fix.

Regards
E.

Here is an example in Visual Basic.NET. If you need C# or other language, please let me know.

Imports OpcLabs.EasyOpc
Imports OpcLabs.EasyOpc.DataAccess
Module Module1
Imports OpcLabs.EasyOpc
Imports OpcLabs.EasyOpc.DataAccess
Module Module1
Sub Main()
Dim client As New EasyDAClient()
Console.WriteLine("Writing multiple item values...")
Dim resultArray As OperationResult() = client.WriteMultipleItemValues( _
New DAItemValueArguments() { _
New DAItemValueArguments("", "OPCLabs.KitServer.2", "Simulation.Register_I2", 12345), _
New DAItemValueArguments("", "OPCLabs.KitServer.2", "Simulation.Register_R4", 234.56)})
Console.WriteLine("Press Enter to continue...")
Console.ReadLine()
End Sub
End Module


There is, however, a bug in the build that was currently posted on this Web (5.00.1081.1). The bug caused that an an empty or zero values were written with WriteMultipleItemValues and WriteMultipleItems. We have fixed this bug, and as of now, an updated build (5.00.1321.1) is posted on the Web. Please us the new one for proper behavior.
