Thread: Taking a Screenshot of a Fullscreen Game

Hey,

I have... i guess a big problem...

I'm trying to capture and save a screenshot of a full screen game (counter strike source) to be exact.
I have tried many ways but all I ever get it a black screen or my desktop.

I'm trying to take a screenshot once every 30 seconds in a timer.

Any help would be appreciated...

Cheers.

What code do you have so far? Check put this library for capturing direct x

You need to capture direct x

Yeah i know that...

I am asking how.

Anyone know how to screenshot DX games???

You would need to use the DirectX SDK (deprecated) or the XNA SDK, both can be downloaded from Microsoft. The video card has to do the work, Windows cannot do it by itself.

Would you have any idea what sort of code i would need?

And how I import it into VB?

So far i have this code

Code:

Imports System.IOImports Microsoft.DirectX
Imports Microsoft.DirectX.Direct3D


Public Class Form1
    Public Shared Function CaptureScreenshot(ByVal Device As Direct3D.Device, ByVal Filename As String, ByVal ImageFormat As Direct3D.ImageFileFormat) As Boolean
        Dim B As Direct3D.Surface
        Try
            B = Device.GetBackBuffer(0, 0, Direct3D.BackBufferType.Mono)
            Direct3D.SurfaceLoader.Save(Filename, ImageFormat, B)
            B.Dispose()
        Catch ex As Exception
            Return False
        End Try
        Return True
    End Function


    Public Shared Function CaptureScreenshot(ByVal Device As Direct3D.Device, ByVal Filename As String) As Boolean
        Return CaptureScreenshot(Device, Filename, Direct3D.ImageFileFormat.Bmp)
    End Function


    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        CaptureScreenshot(Device, "capture.jpg", Direct3D.ImageFileFormat.Bmp)
    End Sub
End Class

Which I got from here (windows - DirectX 10 Screen Capture for Battlefield 3 - Stack Overflow)

Except

Code:

CaptureScreenshot(Device, "capture.jpg", Direct3D.ImageFileFormat.Bmp)

What do i put as the device???

EDIT:
I have added

Code:

Dim D3DDev As Device = Nothing  
 D3DDev = New Device(Manager.Adapters.Default.Adapter, DeviceType.Hardware, Me.Handle, CreateFlags.SoftwareVertexProcessing)

And it seems to work but when i run the application and press button1 i get

Mixed mode assembly is built against version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

First result for web search your last quote was this Mixed mode assembly is built against version ... cannot be loaded in the 4.0 runtime without additional configuration information that says something about useLegacyV2RuntimeActivationPolicy configuration.

I have got the application to load now, but the code

Code:

Dim D3DDev As Device = Nothing  
 D3DDev = New Device(Manager.Adapters.Default.Adapter, DeviceType.Hardware, Me.Handle, CreateFlags.SoftwareVertexProcessing)

Does not work, how do i get my device?

Hello,

As of now i have got my application taking Screenshots outside of the game... but it only takes them of black screen
And when I ingame i get

Code:

A first chance exception of type 'Microsoft.DirectX.Direct3D.DeviceLostException' occurred in Microsoft.DirectX.Direct3D.dll

on this line

Code:

 D3DDev = New Device(Manager.Adapters.Default.Adapter, DeviceType.Hardware, Me.Handle, CreateFlags.SoftwareVertexProcessing, present)

This is the code i'm using

Imports System.IO

Imports Microsoft.DirectX

Imports Microsoft.DirectX.Direct3D





Public Class Form1

    Dim i As Integer = 0

    Public Shared Function CaptureScreenshot(ByVal Device As Direct3D.Device, ByVal Filename As String, ByVal ImageFormat As Direct3D.ImageFileFormat) As Boolean

        Dim B As Direct3D.Surface

        Try

            B = Device.GetBackBuffer(0, 0, Direct3D.BackBufferType.Mono)

            Direct3D.SurfaceLoader.Save(Filename, ImageFormat, B)

            B.Dispose()

        Catch ex As Exception

            Return False

        End Try

        Return True

    End Function





    Public Shared Function CaptureScreenshot(ByVal Device As Direct3D.Device, ByVal Filename As String) As Boolean

        Return CaptureScreenshot(Device, Filename, Direct3D.ImageFileFormat.Bmp)

    End Function





    Private Sub SCREENCAP()

        Dim intX As Integer = Screen.PrimaryScreen.Bounds.Width

        Dim intY As Integer = Screen.PrimaryScreen.Bounds.Height





        Dim present As New PresentParameters

        present.BackBufferCount = 1 'the number of backbuffer

        present.BackBufferFormat = Manager.Adapters(0).CurrentDisplayMode.Format

        present.BackBufferHeight = intY

        present.BackBufferWidth = intX

        present.Windowed = True

        present.SwapEffect = SwapEffect.Discard





        Dim D3DDev As Direct3D.Device

        D3DDev = New Device(Manager.Adapters.Default.Adapter, DeviceType.Hardware, Me.Handle, CreateFlags.SoftwareVertexProcessing, present)





        CaptureScreenshot(D3DDev, "c:\capture" & i & ".jpg", Direct3D.ImageFileFormat.Bmp)

        i = i + 1

    End Sub





    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

        SCREENCAP()

    End Sub

End Class

I'm not really sure what I am doing, never worked with directX or screen capturing before
Any help would be awesome.
Im trying to take fullscreen captures of games.
