Public Sub ServerSyncInvoked(ByVal messageName As String)

public void ServerSyncInvoked(string messageName)

This method is invoked by a separate thread. To avoid multi-threading issues, it should post an event to the UI. If you are using multi-threading, it is recommended that you use a separate connection and use the lock keyword to access any objects shared with the rest of the application.

The following C# code demonstrates how to receive a server synchronization request and perform a synchronization in the UI thread.

using iAnywhere.Data.UltraLite;
public class Form1 : System.Windows.Forms.Form, ULServerSyncListener
{
    private System.Windows.Forms.MainMenu mainMenu1;
    private ULConnection conn;

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

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

	    // Create connection
        ...
    }

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

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

    public void ServerSyncInvoked( string messageName )
    {
        this.Invoke( new EventHandler( ServerSyncHandler ) );
    }

    internal void ServerSyncHandler(object sender, EventArgs e)
    {
        conn.Synchronize();
    }
