Public Sub ActiveSyncInvoked(ByVal launchedByProvider As Boolean)

public void ActiveSyncInvoked(bool launchedByProvider)

此方法由单独的线程调用。为避免多线程问题，它应向 UI 发布一个事件。如果您正在使用多线程，建议您使用一个单独的连接，并使用 lock 关键字来访问与应用程序的其余部分共享的所有对象。

完成同步后，应用程序应调用 ULDatabaseManager.SignalSyncIsComplete 方法向 ActiveSync 的 MobiLink 提供程序发出信号。

• ULDatabaseManager.SignalSyncIsComplete 方法 [UltraLite.NET]

' Visual Basic 导入 iAnywhere.Data.UltraLite。Public Class MainWindow Inherits System.Windows.Forms.Form Implements ULActiveSyncListener

Private conn As ULConnection

Public Sub New(ByVal args() As String) MyBase.New()

' [Windows 窗体设计器] 需要此调用。InitializeComponent()

' 调用 InitializeComponent 后添加任意初始化。ULConnection.DatabaseManager.SetActiveSyncListener( _ "myCompany.myapp", Me _ )

' 创建连接 ...End Sub

Protected Overrides Sub OnClosing( _ ByVal e As System.ComponentModel.CancelEventArgs _ ) ULConnection.DatabaseManager.SetActiveSyncListener( _ Nothing, Nothing _ ) MyBase.OnClosing(e) End Sub

Public Sub ActiveSyncInvoked( _ ByVal launchedByProvider As Boolean _ ) Implements ULActiveSyncListener.ActiveSyncInvoked Me.Invoke(New EventHandler(AddressOf Me.ActiveSyncAction)) End Sub

Public Sub ActiveSyncAction( _ ByVal sender As Object, ByVal e As EventArgs _ ) ' 执行活动同步 conn.Synchronize() ULConnection.DatabaseManager.SignalSyncIsComplete() End Sub End Class

以下代码为 C# 语言等效代码：

 // C#
using iAnywhere.Data.UltraLite;

public class Form1 : System.Windows.Forms.Form, ULActiveSyncListener
{
    private System.Windows.Forms.MainMenu mainMenu1;
    private ULConnection conn;

    public Form1()
    {
        //
        // Required for Windows Form Designer support.
        // InitializeComponent();

        //
        // TODO: Add any constructor code after the
        // InitializeComponent call.
        //
        ULConnection.DatabaseManager.SetActiveSyncListener( _
            "myCompany.myapp", this _
        );

        // Create connection
        ...
    }

    protected override void Dispose( bool disposing )
    {
        base.Dispose( disposing );
    }

    protected override void OnClosing( _
        System.ComponentModel.CancelEventArgs e )
	{
        ULConnection.DatabaseManager.SetActiveSyncListener(null, null);
        base.OnClosing(e);
    }

    public void ActiveSyncInvoked(bool launchedByProvider)
    {
        this.Invoke( new EventHandler( ActiveSyncHandler ) );
    }

    internal void ActiveSyncHandler(object sender, EventArgs e)
    {
        conn.Synchronize();
        ULConnection.DatabaseManager.SignalSyncIsComplete();
    }
}
