ComponentInstaller.CopyFromComponent メソッド

派生クラスによってオーバーライドされた場合、指定したコンポーネントから、インストール時に必要なすべてのプロパティをコピーします。

名前空間: System.Configuration.Install
アセンブリ: System.Configuration.Install (system.configuration.install.dll 内)
構文

Visual Basic (宣言)

Public MustOverride Sub
 CopyFromComponent ( _
    component As IComponent _
)

Visual Basic (使用法)

Dim instance As ComponentInstaller
Dim component As IComponent

instance.CopyFromComponent(component)

public abstract void CopyFromComponent (
    IComponent component
)

C++

public:
virtual void CopyFromComponent (
    IComponent^ component
) abstract

public abstract void CopyFromComponent (
    IComponent component
)

JScript

public abstract function CopyFromComponent
 (
    component : IComponent
)

パラメータ

component: コピー元のコンポーネント。

解説

インストーラは、インストール時に使用できるように、ライブコンポーネントから入手できる全情報を取得して格納しておく必要があります。

使用例

イベントログを作成し、イベントログコンポーネントのプロパティを EventLogInstaller にコピーする、クラス MyInstallClass を定義する例を次に示します。またこの例では、ServiceInstaller が EventLogInstaller と同じ種類のインストールを実行できるかどうかをチェックします。

Visual Basic

Dim myEventLogInstaller As New
 EventLogInstaller()
' Create a source for the specified event log, on local computer.
EventLog.CreateEventSource("MyEventSource", "MyEventLog",
 ".")
' Create an event log instance and associate it with the log .
Dim myEventLog As New EventLog("MyEventLog",
 ".", "MyEventSource")
' Copy the properties that are required at install time from
' the event log component to the installer.
myEventLogInstaller.CopyFromComponent(myEventLog)

EventLogInstaller myEventLogInstaller = new EventLogInstaller();
// Create a source for the specified event log, on local computer.
EventLog.CreateEventSource("MyEventSource","MyEventLog", ".");
// Create an event log instance and associate it with the log .
EventLog myEventLog = new EventLog("MyEventLog", ".",
 "MyEventSource");
// Copy the properties that are required at install time from
// the event log component to the installer.
myEventLogInstaller.CopyFromComponent(myEventLog);

C++

EventLogInstaller^ myEventLogInstaller = gcnew EventLogInstaller;
// Create a source for the specified event log, on local computer.
EventLog::CreateEventSource( "MyEventSource", "MyEventLog", "."
 );
// Create an event log instance and associate it with the log .
EventLog^ myEventLog = gcnew EventLog( "MyEventLog",".","MyEventSource"
 );
// Copy the properties that are required at install time from
// the event log component to the installer.
myEventLogInstaller->CopyFromComponent( myEventLog );

EventLogInstaller myEventLogInstaller = new EventLogInstaller();
// Create a source for the specified event log, on local computer.
EventLog.CreateEventSource("MyEventSource", "MyEventLog", ".");
// Create an event log instance and associate it with the log .
EventLog myEventLog = new EventLog("MyEventLog", ".",
 "MyEventSource");
// Copy the properties that are required at install time from
// the event log component to the installer.
myEventLogInstaller.CopyFromComponent(myEventLog);
