我在Visual Studio 2013中使用DirectX11.1，开发Windows 8商店应用程序。
我已经尝试了几天来了解使用DirectX创建2D UI，就像我以为我可能已经得到它一样，我遇到了一个未经处理的例外我似乎无法忍受摇匀。
“First.exe中0x002E2901处的未处理异常：0xC0000005：访问冲突读取位置0x00000000。”
更新：似乎在'd2dFactory-＆gt; CreateDevice（dxgiDevice.Get（），＆amp; dev2d）之后;' dev2d即将出现。
更新：使用HRESULT，创建设备方法给出错误“E_INVALIDARG”。
（我一直关注http://msdn.microsoft.com/en-us/library/windows/apps/hh780340.aspx）
下面是标题和.cpp文件中的代码。我没有包含任何过去创建ID2D1DeviceContex的内容，因为这是错误发生的地方（只有当我包含它才会发生异常。
