Hello Mr. Zahradnik,
thank you for the quick answer. It will also be helpful for me to get a C# samples. I am an "oldschool" C Programmer, so i understand the most thinks of C#. But VB ist easyier to handle with database connections.
Mit freundlichen Grüßen
Best Regards
D.

Dear Sir,
Thank you for your interest in our products.
As you might have noticed, we tend to have more examples in C# rather than in VB.NET, but that does not mean that VB.NET is any less supported.
Would it be helpful to you if we re-write following existing C# examples to VB.NET (they are all WinForms app; I guess that's what your environment is)?
• EasyOpcDANetDemo1: This is a clone of the Demo application that ships with the QuickOPC.NET product. The application shows most product functions, including the browsing forms, OPC property access, and event-based subscriptions.
• HmiScreen: Windows Forms application that shows how to use implement an HMI screen by storing OPC Item IDs in the Tag property of screen controls, and animate the controls by subscribing to all items at once. Also shows a possibility how to write to an OPC item form the screen.
• SubscribeToMany: Demonstrates and measures performance with large number of subscribed OPC items. [optionally]
In addition, we can "throw in" an example of reading/writing arrays of values.
This can be probably be done by end of this week. I apologize that due to the holiday season it's somewhat difficult to do it faster.
Please let me know.
Yours sincerely,
Zbynek Zahradnik, OPC Labs

Hello,
i am testing your EasyOPC.Net tools. Do you have some more samples for VB2010, not just th very eays ones?
Maybe for handling subscriptions and reading / writing arrays of values ?
Thanks in advance.
