VB.NET DirectX Screen Capture

[Maximus]

Am codul :

Imports System.IO
Imports Microsoft.DirectX.Direct3D
Imports Microsoft.DirectX

Public Class form1
    Public GraphicsDevice As Direct3D.Device = Nothing
    Public presentParams As PresentParameters = New PresentParameters

    Public Sub InitializeGraphics()

        Dim current As Format = Direct3D.Manager.Adapters(0).CurrentDisplayMode.Format
        presentParams.SwapEffect = SwapEffect.Discard
        presentParams.BackBufferFormat = current
        presentParams.Windowed = True
        presentParams.BackBufferHeight = 0
        presentParams.BackBufferWidth = 0
        GraphicsDevice = New Direct3D.Device(0, Direct3D.DeviceType.Hardware, Me, CreateFlags.SoftwareVertexProcessing, presentParams)

    End Sub

    Public Function CaptureScreenshot(ByVal Device As Direct3D.Device, ByVal Filename As String, ByVal ImageFormat As Direct3D.ImageFileFormat) As Boolean
        Dim Ssurface As Direct3D.Surface
        Dim current As Format = Direct3D.Manager.Adapters(0).CurrentDisplayMode.Format

        Ssurface = Device.GetBackBuffer(0, 0, BackBufferType.Mono)
        Direct3D.SurfaceLoader.Save(Filename, ImageFormat, Ssurface)
        Ssurface.Dispose()
        Return True
    End Function


    Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.Load
        Timer1.Enabled = True
    End Sub
    Dim cc As Integer = 1
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        InitializeGraphics()
        CaptureScreenshot(GraphicsDevice, cc & ".bmp", ImageFileFormat.Bmp)
        cc += 1
    End Sub
End Class

Incerc sa fac un screenshot cand joc battlefield 3. din cate am inteles doar folosind directx merge facut screenshot-ul.

Cand dau Debug imi da :

Error 2 'Device' is a type and cannot be used as an expression.

Error 1 'DirectX' is not declared. It may be inaccessible due to its protection level.

si nu inteleg dc.

Ma poate ajuta cineva?? Multumesc anticipat.
