![]() | ConstructionEnabledAttribute(Boolean) | Initializes a new instance of the ConstructionEnabledAttribute class, setting Enabled to the specified value. |
| Name | Description | |
|---|---|---|
![]() | Equals | Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Returns the hash code for this instance. (Inherited from Attribute.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | IsDefaultAttribute | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.) |
![]() | Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |

| Name | Description | |
|---|---|---|
![]() ![]() | _Attribute::GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |

The following code example demonstrates the use of this attribute to associate an object constructor string with a ServicedComponent class.
// Accept a constructor string. [ConstructionEnabled] public ref class EmployeeInformation: public ServicedComponent { private: // The employee's user name and salary. String^ accountName; double salary; public: // Get the employee's name. All users can call this method. String^ GetName() { return (accountName); } // Set the employee's salary. Only managers can do this. void SetSalary( double ammount ) { if ( SecurityCallContext::CurrentCall->IsCallerInRole( "Manager" ) ) { salary = ammount; } else { throw gcnew UnauthorizedAccessException; } } // Get the employee's salary. Only the employee and managers can do this. double GetSalary() { if ( SecurityCallContext::CurrentCall->DirectCaller->AccountName == accountName || SecurityCallContext::CurrentCall->IsCallerInRole( "Manager" ) ) { return (salary); } else { throw gcnew UnauthorizedAccessException; } } protected: // Use the constructor string. // This method is called when the object is instantiated. virtual void Construct( String^ constructorString ) override { accountName = constructorString; } };
