範例
下列範例會定義 類別 ,這個類別 MyInstallClass
會建立事件記錄檔,並將事件記錄元件 EventLogInstaller的屬性複製到 。 它也會檢查 是否可以 ServiceInstaller 執行與 相同的安裝 EventLogInstaller類型。
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);
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)
備註
安裝程式應該會從即時元件取得其所有資訊,並儲存在安裝時間使用。
