Yes, I can share a sample visual studio solution if you tell me that is safe to put the license in it.
Otherwise it is very simple.
I uninstalled all the version of EasyOPC I had on my pc (not necessary) and also uninstalled all the license I previously installed with the license manager application.
(see attached screenshot)
The code is simple with just one class:
The output is in the attached screenshot, you can see that the EasyDAClient is not getting the license.

The code is simple with just one class:
Code:
using OpcLabs.BaseLib.ComponentModel;
using OpcLabs.EasyOpc.DataAccess;
using OpcLabs.EasyOpc.UA;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApp
{
class Program
{
public static void LoadLicense()
{
// Register a license that is we embed as a managed resource in this program.
// The first two arguments should always be "QuickOPC" and "Multipurpose".
// The third argument determines the assembly where the license resides.
// The fourth argument is the namespace-qualified name of the managed resource.
LicensingManagement.Instance.RegisterManagedResource("QuickOPC", "Multipurpose",
Assembly.GetExecutingAssembly(),
"ConsoleApp.Key-Permanent-ShareIt-1999420671-20210120.bin");
// Instantiate the client object, obtain the serial number from the license info, and display the serial number.
var client = new EasyDAClient();
long serialNumber = (uint)client.LicenseInfo["Multipurpose.SerialNumber"];
Console.WriteLine("SerialNumber: {0}", serialNumber);
// Instantiate the client object, obtain the serial number from the license info, and display the serial number.
var clientUA = new EasyUAClient();
serialNumber = (uint)clientUA.LicenseInfo["Multipurpose.SerialNumber"];
Console.WriteLine("SerialNumber: {0}", serialNumber);
}
public static bool IsDemo()
{
// Instantiate the client object.
var client = new EasyDAClient();
// Obtain the serial number from the license info.
long serialNumber = (uint)client.LicenseInfo["Multipurpose.SerialNumber"];
// Display the serial number.
Console.WriteLine("SerialNumber: {0}", serialNumber);
// Determine whether we are running as demo or trial.
if ((1111110000 <= serialNumber) && (serialNumber <= 1111119999))
return true;
else
return false;
}
static void Main(string[] args)
{
Console.WriteLine(IsDemo());
LoadLicense();
Console.WriteLine(IsDemo());
}
}
}
The output is in the attached screenshot, you can see that the EasyDAClient is not getting the license.
