Restoring SQL 2005 Database

Hi All,

I'm trying to restore a database (16GB) through my application. The cmd.BeginExecuteNonQuery completes and returns statistics after running for approx 20 minutes but according to SSMS, the database is still being restored even after restarting the PC.

Code for restoring DB:

vb Code:

Private Sub btnRestoreDB_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRestoreDB.Click
 
        Me.RichTextBoxResult.Clear()
 
        If ValidateInput(Me.GroupBox4) = False Then
 
            Dim RestoreSQL As String = "USE master RESTORE DATABASE [" & Me.ComboBoxDBToRestore.Text & _
            "] FROM  DISK = N'" & FileToSaveFolderPath & "\" & FileToSaveFileName & "' " & _
            "WITH  FILE = 1,  MOVE N'FilePD' TO N'" & Me.txtboxUserDataLoc.Text & "\" & Me.ComboBoxDBToRestore.Text & ".mdf', " & _
            "MOVE N'PD_log' TO N'" & Me.txtboxUserTrnLoc.Text & "\" & Me.ComboBoxDBToRestore.Text & "_Log.ldf', " & _
            "REPLACE"
 
            If MessageBox.Show("Are you sure you want to RESTORE the " & Me.ComboBoxDBToRestore.Text & " database?", "Restore Database", MessageBoxButtons.YesNo, MessageBoxIcon.Question) = Windows.Forms.DialogResult.Yes Then
                Me.RichTextBoxResult.Text = ExecuteSQLStmt(RestoreSQL)
                Me.btnSetDBParameters.Enabled = True
                Me.btnUpdateViews.Enabled = True
            End If
        Else
            MessageBox.Show("Database to Restore / User Data Location / User Transaction Location must be selected...", "Restore Database", MessageBoxButtons.OK, MessageBoxIcon.Error)
        End If
 
    End Sub

vb Code:

Public Function ExecuteSQLStmt(ByVal sqlStmt As String)
 
        Dim Result As String = String.Empty
 
        Dim ConnectionString As String = GetConnectionString()
        SQLConnection = New SqlConnection(ConnectionString)
        Dim cmd As New SqlCommand(sqlStmt, SQLConnection)
        cmd.CommandTimeout = 0
 
        SQLConnection.FireInfoMessageEventOnUserErrors = True
        SQLConnection.StatisticsEnabled = True
 
        ' Open the connection
        If SQLConnection.State = ConnectionState.Open Then
            SQLConnection.Close()
        End If
 
        Using SQLConnection
            Try
 
                Dim statistics As IDictionary = SQLConnection.RetrieveStatistics()
                Dim bytesReceived As Long = CLng(statistics.Item("BytesReceived"))
                Dim bytesSent As Long = CLng(statistics.Item("BytesSent"))
                Dim IduRows As Long = CLng(statistics.Item("IduRows"))
                Dim ConnectionTime As Long = CLng(statistics.Item("ConnectionTime"))
                Dim ExecutionTime As Long = CLng(statistics.Item("ExecutionTime"))
                Dim Count As Integer = 0
 
                SQLConnection.Open()
 
                Dim SQLresult As IAsyncResult = cmd.BeginExecuteNonQuery()
                While Not SQLresult.IsCompleted
                    Result = "Waiting " & Count
                    Threading.Thread.Sleep(100)
                    Count += 1
                    Application.DoEvents()
                End While
 
                Result += Environment.NewLine & Environment.NewLine & _
                "**********Statistics For The Curious**********" & Environment.NewLine & Environment.NewLine & _
                "Total Counters: " & statistics.Count.ToString() & Environment.NewLine & _
                "Connection Time: " & ConnectionTime.ToString() & Environment.NewLine & _
                "Execution Time: " & ConnectionTime.ToString() & Environment.NewLine & _
                "Bytes Received: " & bytesReceived.ToString() & Environment.NewLine & _
                "Bytes Sent: " & bytesSent.ToString() & Environment.NewLine & _
                "Rows Affected: " & IduRows.ToString()
            Catch ae As SqlException
                Result = ae.Message.ToString()
            Catch ae As InvalidOperationException
                Result = ae.Message.ToString()
            Catch ae As Exception
                Result = ae.Message.ToString()
            End Try
        End Using
        Return Result
    End Function
