来自D3DX11CreateEffectFromMemory的E_NOINTERFACE结果 [英] E_NOINTERFACE result from D3DX11CreateEffectFromMemory

问题描述

我刚刚开始使用Dx11。 D3DX11CreateEffectFromMemory正在返回E_NOINTERFACE。

我知道E_NOINTERFACE在COM方面的含义，但我不知道如何解决这个问题。着色器编译器声称已成功编译着色器代码。

我将.fxo（编译的着色器）文件加载到缓冲区中。通过代码，调试器在指示的行上出现0x8004002错误：

对不起，调试器指示的行是截图中的第20行。

感谢任何见解

解决方案

我遇到了同样的错误，你使用的是Windows 7，我猜这个函数不被支持，一些接口只适用于Windows 8，但MSDN没有详细描述。请从DirectX / XNA论坛查看此问题。 p>

I'm just getting started with Dx11. D3DX11CreateEffectFromMemory is returning E_NOINTERFACE.

I know what E_NOINTERFACE means in terms of COM, but I don't know how to resolve this. The shader compiler claims to have successfully compiled the shader code.

I'm loading the .fxo (complied shader) file into a buffer. Stepping through the code, the debugger fails on the indicated line with the 0x8004002 error:

Sorry, the line indicated by the debugger is line 20 in the screenshot.

thanks for any insights

解决方案

I met the same error before, but with a different function, If you are using Windows 7, I guess this function was not supported, some interfaces only works on Windows 8, but MSDN does not describe it in details. take a look of this question from the DirectX/XNA forum.
