EndRestore Method

In This Topic

Ends an asynchronous invocation of the Restore method.

Syntax

Visual Basic
C#

'Declaration
 
Public Sub EndRestore( _
   ByVal result As IAsyncResult _
)

public void EndRestore( 
   IAsyncResult result
)

Parameters

result: The System.IAsyncResult returned by BeginRestore.

Remarks

The function ends an asynchronous backup that is started with BeginRestore. A pair of asynchronous functions (BeginRestore and EndRestore) can be used instead of the synchronous function Restore to gain more performance and flexibility in your application.

Example

This sample demonstrates performing async backup and restore operations.

csharp

public void DumpIt(PgSqlConnection conn)
{
        conn.Open();
        PgSqlDump pgSqlDump = new PgSqlDump();
        pgSqlDump.Connection = conn;
        pgSqlDump.Schema = "public";
        pgSqlDump.Tables = "dept;emp";
        pgSqlDump.IncludeDrop = true;
        IAsyncResult Result = pgSqlDump.BeginBackup("d:\\dump.dmp");
        while (!Result.IsCompleted)
        {
                Console.Write(".");
                //Perform here any operation you need
        }
        pgSqlDump.EndBackup(Result);
        Console.WriteLine("Dumped.");
        conn.Close();
}

public void UnDumpIt(PgSqlConnection conn)
{
        conn.Open();
        PgSqlDump pgSqlDump = new PgSqlDump();
        pgSqlDump.Connection = conn;
        IAsyncResult Result = pgSqlDump.BeginRestore("d:\\dump.dmp");
        while (!Result.IsCompleted)
        {
                Console.Write(".");
                //Perform here any operation you need
        }
        pgSqlDump.EndRestore(Result);
        Console.WriteLine("Restored.");
        conn.Close();
}

Visual Basic

Public Sub DumpIt(conn As PgSqlConnection)
        conn.Open()
        Dim pgSqlDump As New PgSqlDump()
        pgSqlDump.Connection = conn
        pgSqlDump.Schema = "public"
        pgSqlDump.Tables = "dept;emp"
        pgSqlDump.IncludeDrop = True
        Dim Result As IAsyncResult = pgSqlDump.BeginBackup("d:\dump.dmp")
        While Not Result.IsCompleted
                'Perform here any operation you need
                Console.Write(".")
        End While
        pgSqlDump.EndBackup(Result)
        Console.WriteLine("Dumped.")
        conn.Close()
End Sub

Public Sub UnDumpIt(conn As PgSqlConnection)
        conn.Open()
        Dim pgSqlDump As New PgSqlDump()
        pgSqlDump.Connection = conn
        Dim Result As IAsyncResult = pgSqlDump.BeginRestore("d:\dump.dmp")
        While Not Result.IsCompleted
                'Perform here any operation you need
                Console.Write(".")
        End While
        pgSqlDump.EndRestore(Result)
        Console.WriteLine("Restored.")
        conn.Close()
End Sub
