RegistrationErrorInfo Class

Retrieves extended error information about methods related to multiple COM+ objects. This also includes methods that install, import, and export COM+ applications and components. This class cannot be inherited.

System::Object
  System.EnterpriseServices::RegistrationErrorInfo

Namespace:  System.EnterpriseServices
Assembly:  System.EnterpriseServices (in System.EnterpriseServices.dll)

[SerializableAttribute]
public ref class RegistrationErrorInfo sealed

The RegistrationErrorInfo type exposes the following members.

  NameDescription
Public propertyErrorCodeGets the error code for the object or file.
Public propertyErrorStringGets the description of the ErrorCode.
Public propertyMajorRefGets the key value for the object that caused the error, if applicable.
Public propertyMinorRefGets a precise specification of the item that caused the error, such as a property name.
Public propertyNameGets the name of the object or file that caused the error.

  NameDescription
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The following code example shows how to retrieve extended error information about methods related to multiple COM+ objects.

try
{
   String^ applicationName = "Queued Component";
   String^ typeLibraryName = nullptr;
   RegistrationHelper^ helper = gcnew RegistrationHelper;
   // Call the InstallAssembly method passing it the name of the assembly to  
   // install as a COM+ application, the COM+ application name, and  
   // the name of the type library file. 
   // Setting the application name and the type library to NULL (nothing in Visual Basic .NET 
   // allows you to use the COM+ application name that is given in the assembly and  
   // the default type library name. The application name in the assembly metadata  
   // takes precedence over the application name you provide to InstallAssembly. 
   helper->InstallAssembly( "C:..\\..\\QueuedComponent.dll",  applicationName,  typeLibraryName, InstallationFlags::CreateTargetApplication );
   Console::WriteLine( "Registration succeeded: Type library {0} created.", typeLibraryName );
   Console::Read();

   // Create a RegistrationConfig object and set its attributes 
   // Create a RegistrationHelper object, and call the InstallAssemblyFromConfig 
   // method by passing the RegistrationConfiguration object to it as a  
   // reference object
   RegistrationConfig^ registrationConfiguration = gcnew RegistrationConfig;
   registrationConfiguration->AssemblyFile = "C:..\\..\\QueuedComponent.dll";
   registrationConfiguration->Application = "MyApp";
   registrationConfiguration->InstallationFlags = InstallationFlags::CreateTargetApplication;
   RegistrationHelper^ helperFromConfig = gcnew RegistrationHelper;
   helperFromConfig->InstallAssemblyFromConfig(  registrationConfiguration );
}
catch ( RegistrationException^ e ) 
{
   Console::WriteLine( e->Message );

   // Check whether the ErrorInfo property of the RegistrationException object is null.  
   // If there is no extended error information about  
   // methods related to multiple COM+ objects ErrorInfo will be null. 
   if ( e->ErrorInfo != nullptr )
   {
      // Gets an array of RegistrationErrorInfo objects describing registration errors 
      array<RegistrationErrorInfo^>^ registrationErrorInfos = e->ErrorInfo;

      // Iterate through the array of RegistrationErrorInfo objects and disply the  
      // ErrorString for each object.
      System::Collections::IEnumerator^ myEnum = registrationErrorInfos->GetEnumerator();
      while ( myEnum->MoveNext() )
      {
         RegistrationErrorInfo^ registrationErrorInfo = (RegistrationErrorInfo^)( myEnum->Current );
         Console::WriteLine( registrationErrorInfo->ErrorString );
      }
   }
   Console::Read();
}
