In d3d9, we can normally use DX d3d9 that creates non self process, almost compatible with all systems.
But when we use Dx11 to create DX of non self windows, some systems will be created. If someone uses the same problem, let's discuss it together.
Here is my part of the code, thanks!
WNDCLASSEX wc = { sizeof(WNDCLASSEX), CS_CLASSDC, WndProc, 0L, 0L, GetModuleHandle(NULL), NULL, NULL, NULL, NULL, _T("ImGui Example"), NULL };
RegisterClassEx(&wc);
HWND hwnd = CreateWindow(_T("ImGui Example"), _T("ImGui DirectX11 Example"),
WS_OVERLAPPEDWINDOW, 100, 100, 1280, 800, NULL, NULL, wc.hInstance, NULL);
CreateDeviceD3D （hwnd ）;
If you use your own window, you will succeed!
