Hey @spazzarama !

Is there any possibility to easily add Lines Drawing to DXOverlayEngine in directX 11 ??

• Is it possible to make PresentHook work with hooked APP resizing?

My application captures a screenshot of a 32-bit DirectX application (BlueStacks) whenever it needs it. It works fine, but after about 150 calls, it crashes BlueStacks (not the program that is performing the capture). So I tested it with the "Load Test" button on the TestScreenshot application. It does not crash BlueStacks. However, if I execute the code below from a button click in the TestScreenshot application, it does crash BlueStacks. Is there something I am doing wrong with this? Here is the code:

private void button1_Click(object sender, EventArgs e)
{ 
    new Thread(testCapture).Start();
}
public void testCapture()
{
    for (int i = 0; i < 200; i++)
    {
        Bitmap b = _captureProcess.CaptureInterface.GetScreenshot().CapturedBitmap.ToBitmap();
        b.Dispose();
     }
}

Dear Spazzarama,

I've noticed that, when capturing VLC, the memory footprint of VLC remains stable, until I start capturing screenshots. In that case, VLC's memory consumption will quickly reach > 1 Gb (on Windows 8). How can I prevent this from happening?

Cheers,
Erik

That is a combined implementation between your library and the one stored in:
https://github.com/HearthstoneTracker/HearthstoneTracker

I've removed some extra files and tried to go back to as much of the basic that I can.

I've got the font rendering now without any issues and I'll be working on your overlay engine as well (that's another thing all together).

I have two issues with mine currently that I can't explain.

Ghosting as seen here:

The top left smaller one is the original.

Occasional crashing when switching between full screen/windowed but with no consistent behavior.

Is this something you've seen or anyone else viewing this issue?

Ironically while in-game sometimes the FPS will lock itself to an NPC name and even if I rotate the camera it sicks with the NPC. Down the road that would be awesome to do on purpose, like drawing an arrow in the direction to run to avoid something.

Thanks for your hard work!

For example i added some breakpoints in the Capture project in the FramesPerSecond.cs but when i'm running the program what i'm doing it never stop at this breakpoints.
If i'm adding breakpoints to the Interface part of the Capture project it does get and stop at this breakpoints.

Any ideas why it never stop at the FramesPerSecond.cs ? And can i fix it ?

Just to mention if it's any important i'm running the program as admin.

Hello,

First, thank you so much for creating this tool! Without it I don't know how I'd capture screenshots from Direct3D games.

Most games (like Portal 2) work fine using the capture.dll straight from a clone of master (ie: I made no changes to the Direct3DHook code). When I try to get screenshots from Rise of the Tomb Raider the following exception occurs:

DXHookD3D11: PresentHook: Request Start

DXHookD3D11: PresentHook: Exeception: SharpDX.SharpDXException: SharpDX.SharpDXException: HRESULT: [0x80070057], Module: [General], ApiCode: [E_INVALIDARG/Invalid Arguments], Message: The parameter is incorrect.

When I load the symbols for capture.dll the debugger never stops at the code listed in this exception. For reference, I have DirectX12 installed and am running Windows 10. I've tried the game with DirectX 12 enabled and disabled.

This could very well be an issue with my code, but that exception doesn't tell me what argument is wrong or why it is wrong.

Any help would be greatly appreciated. Thank you!

Upon further inspection using a bigger image, recreating a new ImageElement every frame does indeed create a memory leak.

Some code.

The bitmap created on start up:
var bm = new Bitmap(/* path to big image*/);

The main loop:

using (Bitmap doubleBuffer = new Bitmap(ScreenSize.Width, ScreenSize.Height,
            PixelFormat.Format32bppArgb))
{
    using (var graphics = Graphics.FromImage(doubleBuffer))
    {
        graphics.DrawImage(bm, new Point(0, 0));
    }

    DirectXHook.SetBitmap(doubleBuffer);
}

Same results can be achieved by just calling SetBitmap without a doublebuffer.

DirectXHook.SetBitmap(bm);

SetBitmap method, where this.OverlayEngine.Overlays[0].Elements[1] is an ImageElement

((ImageElement)this.OverlayEngine.Overlays[0].Elements[1]).Dispose();
this.OverlayEngine.Overlays[0].Elements.RemoveAt(1);
this.OverlayEngine.Overlays[0].Elements.Add(new Common.ImageElement(bt, true)
{
    Location = new System.Drawing.Point(0, 0)
});

this.OverlayEngine.FlushCache();

Finally, FlushCache method

public void FlushCache()
{
    lock (_imageCache)
    {
        foreach (var dxImage in _imageCache)
        {
            dxImage.Value?.Dispose();
            ((ImageElement)dxImage.Key).Dispose();
        }

        foreach (var element in Overlays[0].Elements.OfType<ImageElement>())
        {
            DXImage result = ToDispose(new DXImage(_device, _deviceContext));
            result.Initialise(element.Bitmap);
            _imageCache[element] = result;
        }
    }
}

When trying to Inject to XComEW.exe TestScreenshot produces the exception below and fails.

The test is on a Steam game XCOM Enemy Within, running on Windows 8.1 64bit
As a positive result, the Steam game Wasteland 2 overlays work fine on the same machine (using Direct3D v9)

I'm not compentent to understand any of the below I'm afraid, so I was hoping you could determine what the issue is.

The game in this case is using DX9.
If i just run the game and make many times Alt+Tab(to return back to windows) it's working good no problems i can keep making Alt+Tab and return to the game and so on.

But once i did inject and now im in the game when i'm doing Alt+Tab after one time or two times the game crash for example: BouT2.exe has stopped working...
And it happen only after doing inject in the program.

I can make choose debug or close if i make debug using my visual studio 2012 i see:

Unhandled exception at 0x76FDF8A2 (ntdll.dll) in BouT2.exe: 0xC0000005: Access violation writing location 0x0000009C.

Why it happen only after making inject and then when doing in the game Alt+Tab to get to the windows ? And idea how to solve it ?

Can't remember the exact scenario now, but under some circumstances the DirectX 11 library will be loaded for a DirectX 9/10 application.

The current logic will incorrectly choose DirectX 11. Instead we could hook all loaded DirectX versions and then we will be correctly capturing which ever is actually presenting.

I'm running battlefield bad company 2 and it's working on dx11.
When i'm clicking on the Request Capture button after some seconds it's throwing an exception in Form1.cs in the method DoRequest() the exception message is:

Could not set process window to the foreground

It didn't happen on DX9 game only on this battlefield bad company 2.

This is the full exception error message:

Can you make Direct3DHook available on NuGet?

Hello Justin,

After the last commit I think something in Direct3DHook got broken. After injecting into any game the game FPS becomes too low to play and the TestScreenshot software gives an error:

No FPS overlay is also coming. Just the huge FPS lag and this nullreference error continuously.

Hope you will solve it soon.

Thanks in advance....

I try to inject into 64 bit game, but have this exception.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the

The application must also be compiled with debugging

For example:

<configuration>

</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

I am sure that the directory of TestScreenshot.exe has the dll "EasyHook32.dll".
So why would this happened?

For some games, such as Guns of Icarus or Aerena - Clash of Champions, I get the following error:

For Guns of Icarus it happens if I attach and then detach before exiting the game, and then on exit, even though everything should be detached, the error is shown and the game crashes.

I believe the issue is occuring for any game that tries to change resolution for whatever reason after it has be attached and detached. It seems like some disposal is not happening fully or properly, something is lingering? What could it be?

How to overlay a plain red 2D rectangle with your library?

Specificially, with the SharpDX.Direct3D9.Device available from the library that sets up a Direct3D v9 device for me, so I'm hoping to be able to use that?

Found a tutorial on how to use Direct2D1 to draw a basic rectangle, but the code seems to be dependent on a Direct3D11 device, which I don't have - I need to be able to get the job done without Direct3D11 and without Direct3D10

unsafe int PresentHook(IntPtr devicePtr, SharpDX.Rectangle* pSourceRect, SharpDX.Rectangle* pDestRect, IntPtr hDestWindowOverride, IntPtr pDirtyRegion)
{
    _isUsingPresent = true;

    SharpDX.Direct3D9.Device device = (SharpDX.Direct3D9.Device)devicePtr;

    // How to draw rectangle here?

    if (pSourceRect == null || *pSourceRect == SharpDX.Rectangle.Empty)
        device.Present();
    else
    {
        if (hDestWindowOverride != IntPtr.Zero)
            device.Present(*pSourceRect, *pDestRect, hDestWindowOverride);
        else
            device.Present(*pSourceRect, *pDestRect);
    }
    return SharpDX.Result.Ok.Code;
}

I asked this question elsewhere, but noone knew how to use the managed code you have provided:
http://stackoverflow.com/questions/31099504/drawing-a-2d-rectangle-with-sharpdx

Hi,

I am currently using your great program to capture screenshots from DirectX devices like VLC or a game. As I am no DirectX expert, I wonder if you can help me with two issues:

• When selecting the program to hook, I can enter the name of a program that has no DirectX support (e.g. notepad). This causes your program to stop responding. Do you know how I can test whether a program runs under DirectX (so I should be able to inject)?
• When the captured program is running in windowed mode, what is the size of the visible DirectX surface? E.g. when I capture VLC, its size also contains the Window frame, and is therefore larger than the actual display surface.

Finally, as you are also the author of Easyhook, I wonder if it is possible to remove the hook injected via Easyhook? And is there a way to test whether an application is already hooked (or if I try to hook an app twice, will it only be hooked once)?

Thanks for any help you can give me!
Erik

the snapshot function doesn't work if the application calls EndScene multiple times before swapping the framebuffers.

however, hooking IDirect3DDevice9::Present method instead of EndScene, using the eaxact same method body, works. (tested with DirectX SDK samples)

Hey,

I don't know if you're still active on this project, but I have been playing with your code and found a severe memory leak.

The Screenshot (MarshalByRefObject) object is never released and it doesn't implement IDisposable.

If capturing a lot of screenshots, memory in the target process keeps growing.

In my case, this resulted in a OOM exception after ~30 seconds of getting consecutive screenshots.

Fix is simple, implement IDisposable, and call RemotingServices.Disconnect(this).

Then, make sure to call Dispose (or the using() construct) in the client application.

public class Screenshot : MarshalByRefObject, IDisposable
{
    private bool _disposed;

    public Screenshot(Guid requestId, byte[] capturedBitmap)
    {
        _requestId = requestId;
        _capturedBitmap = capturedBitmap;
    }

    ~Screenshot()
    {
        Dispose(false);
    }

    /// <summary>
    /// Disconnects the remoting channel(s) of this object and all nested objects.
    /// </summary>
    private void Disconnect()
    {
        RemotingServices.Disconnect(this);
    }

    [SecurityPermissionAttribute(SecurityAction.Demand, Flags = SecurityPermissionFlag.Infrastructure)]
    public override object InitializeLifetimeService()
    {
        //
        // Returning null designates an infinite non-expiring lease.
        // We must therefore ensure that RemotingServices.Disconnect() is called when
        // it's no longer needed otherwise there will be a memory leak.
        //
        return null;

        //var lease = (ILease)base.InitializeLifetimeService();
        //if (lease.CurrentState == LeaseState.Initial)
        //{
        //    lease.InitialLeaseTime = TimeSpan.FromSeconds(2);
        //    lease.SponsorshipTimeout = TimeSpan.FromSeconds(5);
        //    lease.RenewOnCallTime = TimeSpan.FromSeconds(2);
        //}
        //return lease;
    }

    Guid _requestId;
    public Guid RequestId
    {
        get
        {
            return _requestId;
        }
    }

    byte[] _capturedBitmap;
    public byte[] CapturedBitmap
    {
        get
        {
            return _capturedBitmap;
        }
    }

    public void Dispose()
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    protected virtual void Dispose(bool disposing)
    {
        if (!_disposed)
        {
            if (disposing)
            {
                Disconnect();
            }
            _disposed = true;
        }
    }
}

Hope that helps.

While I was trying to run the project on Windows 7 as well, I managed to easily hook to a simple DirectX10 window, but when I tried to hook to a simple DirectX11 window, the target window became unresponsive, followed by the message “Display Driver AMD stopped responding, and was successfully restored”. The project itself kept running, and threw debug messages. The problem seems to be related to SharpDX and calling “draw” to the overlayEngine, but I am still not very familiar with the code.

Please let me know if you can help. I really appreciate it.

Have a great year to come!

In Metro Last Light/Crysis 3/Splinter Cell Blacklist and perhaps others, displayed frames per second are twice what they should be.

I've found a fix for this and I've uploaded a fork. I'm not versed in GitHub but I think I've done it right.
Here's an image after the fix:

Because the fix breaks fps reading for d3d9 and d3d10, I made 2 separate FramesPerSecond11.cs only for d3d11. I also made minor changes to BaseDXHook.cs and DXHookD3D11.cs.

It's a different way of calculating fps based on LastPresentCount, code which I found here on GitHub.

Hey,

another suggestion if you start looking into this project again.

I can't send a pull request as my version has a lot of specific changes for my scenario. but here goes:

To avoid recursing into PresentHook / EndScene too much, you can do something like this:

        private static int presentHookRecurse = 0;

        ....

        if (presentHookRecurse <= 0)
        {
            DoCaptureRenderTarget(device, "PresentEx");
        }

        presentHookRecurse++;
        //    Region region = new Region(pDirtyRegion);
        if (pSourceRect == null || *pSourceRect == SharpDX.Rectangle.Empty)
            device.PresentEx(dwFlags);
        else
        {
            if (hDestWindowOverride != IntPtr.Zero)
                device.PresentEx(dwFlags, *pSourceRect, *pDestRect, hDestWindowOverride);
            else
                device.PresentEx(dwFlags, *pSourceRect, *pDestRect);
        }
        presentHookRecurse--;

Note the ++ / -- on presenthook.

This makes the game not wait for your own code to finish so it can continue at it's own pace.

I think you''ll understand what it does.

Hey I wonder if it's possible to get to 2D Context and render elements like in here (https://english.r2d2rigo.es/2012/07/04/basic-direct2d-drawing-with-sharpdx/). In my case i have D3D11Hook from your approach so i have

SharpDX.Direct3D11.Device _device; and
SharpDX.DXGI.SwapChain _swapChain;

Is there any possibility to render in 2D using (or not) DXOverlayEngine via those variables?
Thanks for help! :)

Use the SharedMemory library to access captured image data in host process rather than IPC.

See InnerException for more detail. ---> System.ApplicationException: STATUS_INTERNAL_ERROR: Unknown error in injected C++ completion routine. (Code: 15)

.

Let me explain.
In the class DXHookD3D11.cs there is a line that write to the screen the frames per second.

new Capture.Hook.Common.FramesPerSecond(new System.Drawing.Font("Arial", 16)) { Location = new System.Drawing.Point(5,5), Color = System.Drawing.Color.Red, AntiAliased = true },

I created inside Capture.Hook.Common a new class called it TimeRunning this is the class code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Capture.Hook.Common
{
public class TimeRunning : TextElement
{
DateTime _startTime = DateTime.Now;
TimeSpan RunTime;

    string _fpsFormat = "{0:c} fps";
    public override string Texts
    {
        get
        {
            return String.Format(_fpsFormat, GetFPS());
        }
        set
        {
            _fpsFormat = value;
        }
    }

    int _frames = 0;
    int _lastTickCount = 0;
    float _lastFrameRate = 0;

    public TimeRunning(System.Drawing.Font font)
        : base(font)
    {
    }

    public override void Frame()
    {
        RunTime = DateTime.Now - _startTime;
    }

    public TimeSpan GetFPS()//float GetFPS()
    {
        return RunTime;//_lastFrameRate;
    }
}

}

Then in the DXHookD3D11.cs inside the Elements =
Under the line with the FramesPerSecond:

new Capture.Hook.Common.TimeRunning(new System.Drawing.Font("Arial", 16)) { Location = new System.Drawing.Point(5,30), Color = System.Drawing.Color.Red, AntiAliased = true }

So now it look like this:

_overlayEngine.Overlays.Add(new Capture.Hook.Common.Overlay
{
Elements =
{
new Capture.Hook.Common.FramesPerSecond(new System.Drawing.Font("Arial", 16)) { Location = new System.Drawing.Point(5,5), Color = System.Drawing.Color.Red, AntiAliased = true },
new Capture.Hook.Common.TimeRunning(new System.Drawing.Font("Arial", 16)) { Location = new System.Drawing.Point(5,30), Color = System.Drawing.Color.Red, AntiAliased = true }
}
});

But when running the program and inject to a game i'm getting this exception:

Debug: DXHookD3D11: PresentHook: Exeception: System.IndexOutOfRangeException: System.IndexOutOfRangeException: Index was outside the bounds of the array.
at Capture.Hook.DX11.DXFont.GetCharRect(Char c) in c:\Temp\hook\Direct3DHook-master\Capture\Hook\DX11\DXFont.cs:line 251
at Capture.Hook.DX11.DXSprite.DrawString(Int32 X, Int32 Y, String text, Int32 R, Int32 G, Int32 B, Int32 A, DXFont F) in c:\Temp\hook\Direct3DHook-master\Capture\Hook\DX11\DXSprite.cs:line 258

How can i fix it ? I want that the TimeRunning will be display on screen under the FramesPerSecond.

For example this line in DXHookD3D11.cs write on the screen the fps(frames per second).

new Capture.Hook.Common.FramesPerSecond(new System.Drawing.Font("Arial", 16)) { Location = new System.Drawing.Point(5,5), Color = System.Drawing.Color.Red, AntiAliased = true }

Now let's say i want to write on screen something else for example the words "Hello World" on location instead 5,5 but 5,30

How can i do it ? So when i'm running the game a Directx 11 game i will see the frapes per second and under it i will see the text "Hello World"

I tried to read about how making a Font in directx11 . For example i searched in google and found about DirectWrite: http://sharpdx.org/documentation/api/n-sharpdx-directwrite
But i didn't understand how to use it since in the Capture project the SharpDX dosen't have the namespace DirectWrite.

Maybe you know and can show me how to add more text on screen ? Like it show the frames per second on screen so show other texts.

I found how to do it in DXHookD3D9.cs but in the DXHookD3D11.cs it's hard i couldn't find how to dit yet.

Idea is to finish implementing an Overlay engine that can render for DirectX 9, 10 and 11.

Already asked here: https://easyhook.codeplex.com/workitem/25879

I have this great project running. All is fine. I injected a game client (Hearthstone, DX9). And it shows the ... fps thing.

That is great for testing and works perfect. Now I was thinking about replacing the ... fps with something else, just to test.

But I'm not able to get it working. It does not matter what I change of the String. It always shows up ... fps. Why is it like that?

I changed in DXHookD3D9.cs:

if (this.FPS.GetFPS() >= 1)
                        {
                            font.DrawText(null, String.Format("{0:N0} fps", this.FPS.GetFPS()), 5, 5, SharpDX.Color.Red);
                        }

into...

font.DrawText(null, String.Format("{0:N0} blablabla", this.FPS.GetFPS()), 5, 5, 

I for sure cleaned the project and rebuild it. Nothing helped.

What am I doing wrong? Is there something else I need to rebuild?

Btw changing things of the Forms works. So it seems just not to work on the dll's somehow.

PS: the TakeScreenshot is just working when I chosse "Autodetect". If I take Direct 3D 9 it does not inject into the game. But in the log when I use Autodetect, it tells me Direct 3D 9.

I have no clue =/

Hey, I was just looking into updating EasyHook to the newest version, but I see that you've also put it on Nuget.

Is there anything that would make this transition non trivial? Or has it not been done yet just due to time constraints?

Edit: Should SharpDX be updated while we're at it?

For example i'm running a game inject and hook the game and i see on the game window the frames per second running in this case for example average of 60-61fps.
Now i want that the program will automatic save to the hard disk screenshots captured every second 60-61 images. Just like the program get from the game if it's 60fps then save 60 images on hard disk in a second if it change to 43fps then now save 43 images to the hard disk.

I did changes and added my code to the file DXHookD3D9.cs

This is the changes i did: http://pastebin.com/wc7vxQvD

First at the top i added: long counter = 0;
Then under: #region Screenshot Request i added my own IF with a request inside.
Then more in the bottom inside the ProcessRequest method i added my oqn thread called it t_1 and after this method added my oqn code with my oqn method called: SaveToDiskImageData

The problem is that it's too slow it's not saving to the hard disk 60-61 frames(screenshots/images) per second and another problem is after some time it's wroking when it's saving like 1000 images to the hard disk it's throwing an exception.

What i want to do in general is first to capture and save to the hard disk the images in real time according to the current fps and then later if it will work to create in real time an avi file.

But first how do i make this part to work good ?

This is the link again to the changes i did in DXHookD3D9.cs: http://pastebin.com/wc7vxQvD

For example i create a public variable type bool in the TestScreenshot project and now i want to use this variable in the Capture project so when i set for example in the TestScreenshot if i click on a button and change the bool variable to false when i use it in the Capture project it will be false and if i click on another button then it will be true also in the Capture project.

How likely do you think using this hook will trip up game modification detection services like VAC or punkbuster? I'm trying to build a custom backlighting solution and am worried about using this with certain games.

A code like

var Bitmap = Screenshot.CapturedBitmap.ToBitmap();
Bitmap.Save(PathToFile);

fails with the "Cannot access closed stream" exception.

Extension method BitmapExtension.ToBitmap is flawed. MSDN states that one must keep the stream open for the lifetime of the Image. It somehow works with the panel in the example application you provided, but saving bitmap ultimately fails.

I tested on "TestScreenshot", It's not sending "Screenshot captured..." text to game.

And another problem is I cant add (for example image) from CaptureProcess It self, cannot find another way to add too (without changing dll)

Hello Justin,

After re-cloning your latest source and compiling it I cannot make it to work with my DirectX9 Games. Injection is all well now. But when I try to capture an image it crashes the game and gives error. I got two types of error for testing it in two different games. The picture of the errors were attached.

1st Game : Call Of Duty 4 Modern Warfare

2nd Game : Need For Speed Most Wanted

Please try to solve these bugs as soon possible. For these the whole project seems broken.

Thanks in advance.....

This one is definitely an improvement/addition to be made, but I'd love to see this have DX12 support added. I know there is a SharpDX12 available so hopefully that is possible. I'm currently working around this project at the moment for my own, and need to impliment DX12 anyway so perhaps if I get it working I can send it over to try and help you. I'm certainly not knowledgeable enough to do it alone though.
