我的D3D11CreateDeviceAndSwapChain（）有問題。我以爲我在prev線程中得到了一個解決方案，所以我已經將它標記爲已解決。 [Create Swap Chain Failed創建交換鏈失敗2.0
貌似我騙了自己，當我不小心返回HRESULT爲bool ...
我一直在爭取這個問題&整天還沒有計算出來。這裏有大量關於輸入輸出&調試信息...
1]以建議使用未知與非空vAdapter： Debug Pic http://content.wuala.com/contents/RandomClown/Public/RandomCrap/Debug%201.png
2]繼離開DX樣本它空&使用類型的硬件： Debug Pic http://content.wuala.com/contents/RandomClown/Public/RandomCrap/Debug%202.png

感謝閱讀。希望這次能找到解決方案。
很抱歉聽到。您忽略了MSDN中某處提供的另一條建議：當您使用全屏時，您應該創建一個窗口化交換鏈並在之後將其設置爲全屏。無論哪種方式，因爲你沒有做全屏：你是否嘗試將刷新率值保持爲0？此外，快速瀏覽我的代碼表明我使用DXGI_FORMAT_R8G8B8A8_UNORM，但我目前不知道這是否是正確的模式。正在進行中:-) –
是的，我處於窗口模式，並且我的刷新率爲0.我將嘗試該顏色模式。 – RandomClown
