Screenshot fullscreen game using DirectX 10/11 - c++

Question

I searched all day for answers on this topic and this is what I found:
WinAPI screenshot - No
You can take screenshots using outdated directx 9
You can take screenshots using Hook with new DirectX
What I already tried:
#include <cstdio>
#include "screenshoter.h"
#include <d3d9.h>
#include <wincodec.h>
#include <Windows.h>
#include <iostream>
#include <string>
#include <Psapi.h>
#include <algorithm>
#include <vector>
HWND targetHWND = nullptr;
BOOL CALLBACK enumWindowsProc(__in HWND hWnd, __in LPARAM lParam) {
int length = GetWindowTextLength(hWnd);
if (length == 0)
return true;
auto buffer = new TCHAR[512];
memset( buffer, 0, ( 512 ) * sizeof( TCHAR ) );
GetWindowText( hWnd, buffer, 512 );
auto windowTitle = std::string(buffer);
DWORD proc = NULL;
GetWindowThreadProcessId(hWnd, &proc);
GetModuleFileNameEx(OpenProcess(PROCESS_QUERY_LIMITED_INFORMATION, false, proc), nullptr, buffer, 512);
auto filePath = std::string(buffer);
auto pos = filePath.find_last_of('\\');
auto fileName = filePath.substr(pos + 1);
delete[] buffer;
if (windowTitle == "Overwatch" && fileName == "Overwatch.exe")
targetHWND = hWnd;
//std::cout << Title: " << windowTitle << " | Filename: " << fileName << std::endl;
return true;
}
int screenshoter::take() {
std::cout << EnumWindows(enumWindowsProc, NULL) << std::endl;
IDirect3DSurface9* pRenderTarget=NULL;
IDirect3DSurface9* pDestTarget=NULL;
IDirect3D9 *pD3D = Direct3DCreate9(D3D_SDK_VERSION);
IDirect3DDevice9* Device=NULL;
D3DPRESENT_PARAMETERS d3dpp = { 0 };
D3DDISPLAYMODE DisplayMode;
d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
d3dpp.hDeviceWindow = targetHWND;
d3dpp.Windowed = ((GetWindowLong(targetHWND, GWL_STYLE) & WS_POPUP) != 0) ? FALSE : TRUE;
if (FAILED(pD3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, d3dpp.hDeviceWindow, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &Device)))
{
pD3D->Release();
return false;
}
const char file[] = "Pickture.bmp";
// sanity checks.
if (Device == NULL)
return 0;
// get the render target surface.
HRESULT hr = Device->GetRenderTarget(0, &pRenderTarget);
// get the current adapter display mode.
hr = pD3D->GetAdapterDisplayMode(D3DADAPTER_DEFAULT,&DisplayMode);
// create a destination surface.
hr = Device->CreateOffscreenPlainSurface(DisplayMode.Width,
DisplayMode.Height,
DisplayMode.Format,
D3DPOOL_SYSTEMMEM,
&pDestTarget,
NULL);
//copy the render target to the destination surface.
hr = Device->GetRenderTargetData(pRenderTarget, pDestTarget);
//save its contents to a bitmap file.
hr = D3DXSaveSurfaceToFile(file,
D3DXIFF_JPG,
pDestTarget,
NULL,
NULL);
// clean up.
pRenderTarget->Release();
pDestTarget->Release();
return 0;
}
My program searches for game process/window
But the problem is there is no d3dx9.h on my system
So I can't use D3DXIFF_JPG
