Hello,
thanks for compliments...
In C++ with Visual Studio 2010, here are the steps to the simplest Console application:

Select File -> New -> Project. Select Visual C++ / CLR / CLR Console Application, enter Name (e.g. test1), OK.
Select Project -> References. Press "Add New Reference" button. Under the .NET tab, scroll to the right assembly/assemblies - just as in C# Quick Start document. Press OK, OK.
You now have the assembly referenced. The remainder is just in editing the source code. At the bottom of test1.cpp, add:


using namespace OpcLabs::EasyOpc::DataAccess;
using namespace System;

int main(array ^args)
{
EasyDAClient^ client = gcnew EasyDAClient();
Console::WriteLine("Reading item...");
Console::WriteLine(client->ReadItemValue("", "OPCLabs.KitServer.2", "Demo.Ramp"));
Console::WriteLine("Press Enter to continue...");
Console::ReadLine();
return 0;
}


This should do it. Let me know if you need anything else.
Best regards

Hello and congratulations for the fantastic product! I was able to setup a small opc client in a couple of minutes using the windows forms and following the quick start document. However, I am having a hard time doing the same with a console application. The quick start document says: "simply reference the Opclabs... assembly". It is the first time I use VC++ and I have no idea how to do that "simple" task. Can you please provide more specific information? I searched the net but it looks like there are millions of different ways and none seems to work for me. I have VS2010, no .lib files, only the .dlls... how do I do that? I tried to open the consoleapplication1 that came with the package but VS2010 says it cannot be converted, there are a few errors in the logger. So I can't see what settings I need to add to my project in order to link the dll. I hope you can help me. Thank you!!!
