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.
Assembly: System.EnterpriseServices (in System.EnterpriseServices.dll)
The following code example shows how to retrieve extended error information about methods related to multiple COM+ objects.
Try Dim applicationName As String = "Queued Component" Dim typeLibraryName As String = Nothing Dim helper As New 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) MsgBox("Registration succeeded: Type library " & typeLibraryName & " created.") 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 Dim registrationConfiguration As New RegistrationConfig() registrationConfiguration.AssemblyFile = "C:..\..\QueuedComponent.dll" registrationConfiguration.Application = "MyApp" registrationConfiguration.InstallationFlags = InstallationFlags.CreateTargetApplication Dim helperFromConfig As New RegistrationHelper() helperFromConfig.InstallAssemblyFromConfig(registrationConfiguration) Catch e As RegistrationException MsgBox(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 Not (e.ErrorInfo Is Nothing) Then ' Gets an array of RegistrationErrorInfo objects describing registration errors Dim registrationErrorInfos As RegistrationErrorInfo() = e.ErrorInfo ' Iterate through the array of RegistrationErrorInfo objects and disply the ' ErrorString for each object. Dim registrationErrorInfo As RegistrationErrorInfo For Each registrationErrorInfo In registrationErrorInfos MsgBox(registrationErrorInfo.ErrorString) Next registrationErrorInfo End If Console.Read() End Try
