Bug resolved. Thank you.

Thanks. downloading now.

Hello people, this is me trying to learn about OPC. I installed QuickOPC 5.2 .NET and i can't run any demo whatsoever.

It always gives the same exception:
AccessViolationException, Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I am on a win7 pro 64bit machine with visual studio 2012 pro, running elevated VS. i have used the default simulator and matrikon's, the results are the same. what im i doing wrong? i didnt configure anything (maybe thats what im missing), just installed and tried the demos.

EDIT: given this code


var client = new EasyDAClient();
Console.WriteLine("Reading item...");
Console.WriteLine(client.ReadItemValue("", "OPCLabs.KitServer.2", "Demo.Ramp"));
Console.WriteLine("Press Enter to continue...");
Console.ReadLine();

The issue happens on the ReadItemValue call.
I have tried adding
EasyDAClient.ClientParameters.TurnOffActivationSecurity = true;
EasyDAClient.ClientParameters.TurnOffCallSecurity=true;

but it didnt help
