RegisterManagedResource Method

Registers a license located in an embedded managed resource.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Sub RegisterManagedResource( _
   ByVal componentName As String, _
   ByVal licenseId As String, _
   ByVal assembly As Assembly, _
   ByVal resourceNameOrPattern As String _
)

'Usage
 
Dim instance As LicensingManagement
Dim componentName As String
Dim licenseId As String
Dim assembly As Assembly
Dim resourceNameOrPattern As String
 
instance.RegisterManagedResource(componentName, licenseId, assembly, resourceNameOrPattern)

public void RegisterManagedResource( 
   string componentName,
   string licenseId,
   Assembly assembly,
   string resourceNameOrPattern
)

public:
void RegisterManagedResource( 
   String^ componentName,
   String^ licenseId,
   Assembly^ assembly,
   String^ resourceNameOrPattern
)

Parameters

componentName: Name of the licensing component for which the location of the license should be registered. Consult the documentation for the value that corresponds to your product.
licenseId: ID of the license for whose location should be registered. Consult the documentation for the values to be used with your product.
assembly: The assembly in which the embedded managed resource resides.
resourceNameOrPattern: The name of the embedded managed resource containing the license, or a pattern identifying a single such resource.

Exceptions

Exception Description

System.ArgumentException A license resource is already registered for componentName and licenseId.

Exception	Description
System.ArgumentException	A license resource is already registered for componentName and licenseId.
System.ArgumentNullException	A `null` reference (`Nothing` in Visual Basic) is passed to a method that does not accept it as a valid argument. This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

System.ArgumentNullException

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

The same combination of componentName and licenseId must not (and cannot) be registered more than once. An attempt to do so will result in an System.ArgumentException. Be careful not to put the registration code into Web request handlers (without further logic) which are called repeatedly.

The actual presence and validity of the license is not checked at the time when the location is registered. If you want an exception be thrown when the managed resource does not exist or is not accessible, use the RegisterManagedResourceWithExistenceCheck method.

Example

using OpcLabs.BaseLib.ComponentModel;
using OpcLabs.EasyOpc.UA;

namespace UADocExamples.Licensing
{
    partial class _LicensingManagement
    {
        public static void RegisterManagedResource()
        {
            // 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, or a pattern identifying it.
            // We could use precise "UADocExamples.Licensing.Key-DemoOrTrial-WebForm-1999003494-20180611.bin" instead.
            LicensingManagement.Instance.RegisterManagedResource("QuickOPC", "Multipurpose",
                Assembly.GetExecutingAssembly(), "*.Key-*.*");

            // Instantiate the client object, obtain the serial number from the license info, and display the serial number.
            var client = new EasyUAClient();
            long serialNumber = (uint)client.LicenseInfo["Multipurpose.SerialNumber"];
            Console.WriteLine("SerialNumber: {0}", serialNumber);

            // The license we ship for this purpose is a trial license with low runtime limit, so it won't be of much use.
            // But you get the point...
        }
    }
}
