Public NotInheritable Class RegistrationErrorInfo

NameDescription
System_CAPS_pubpropertyErrorCode

Gets the error code for the object or file.

System_CAPS_pubpropertyErrorString

Gets the description of the ErrorCode.

System_CAPS_pubpropertyMajorRef

Gets the key value for the object that caused the error, if applicable.

System_CAPS_pubpropertyMinorRef

Gets a precise specification of the item that caused the error, such as a property name.

System_CAPS_pubpropertyName

Gets the name of the object or file that caused the error.

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodToString()

Returns 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
    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
