How do you create swap chain I always get failure on the CreateSwapChainForHwnd call

Code:

---

DXGI_SWAP_CHAIN_DESC1 desc;
    ZeroMemory(&desc, sizeof(DXGI_SWAP_CHAIN_DESC1));
    desc.BufferCount = 1;
    desc.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT;
    desc.SampleDesc.Count = 1;      //multisampling setting
    desc.SampleDesc.Quality = 0;    //vendor-specific flag
    desc.SwapEffect = DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL;
    desc.Width = 300;
    desc.Height = 300;
    desc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;

    // Create the DXGI device object to use in other factories, such as Direct2D.
    IDXGIDevice3* dxgiDevice;

    // Create swap chain.
    IDXGIAdapter* adapter;
    IDXGIFactory2* factory;
    IDXGISwapChain1* swapchain;

    hr = device->QueryInterface(__uuidof(IDXGIDevice3), (void**)&dxgiDevice);

    hr = dxgiDevice->GetAdapter(&adapter);

    if (SUCCEEDED(hr))
    {

        hr = adapter->GetParent(__uuidof(IDXGIFactory2), (void**)&factory);

        hr = factory->CreateSwapChainForHwnd(
            device,
            m_amahwnd,
            &desc,
            NULL,
            NULL,
            &swapchain
        );

        try
        {
            if (!SUCCEEDED(hr))
            {
                throw(std::invalid_argument("Blah"));
            }
        }
        catch (std::invalid_argument& blah)
        {
            MessageBox(m_amahwnd, L"Blah", L"blah", MB_OK);
        }

I don't know how to get a swap chain created, should I go back and do a CreateDevice*AND*SwapChain?

Hello Goukenfan,

I have not had much exposure to Windows C++ for quite a while but I'll try to help. Just to be clear, the problem you are facing is that line 29 in code above fails i.e.

Code:

---

hr = factory->CreateSwapChainForHwnd(
            device,
            m_amahwnd,
            &desc,
            NULL,
            NULL,
            &swapchain
        );

My first instinct would be to confirm that the factory pointer is not NULL. The next thing I would ask would be about the arguments you are passing into the CreateSwapChainForHwnd method. If in doubt, read the documentation
IDXGIFactory2::CreateSwapChainForHwnd (dxgi1_2.h) - Win32 apps | Microsoft Docs
