嗨..我是DirectX编程的初学者..
以上是代码我试图实现一个directX窗口..
但是当我运行它时，它会因错误而停止。
它说
myprogram.exe中0x00EB167C处的未处理异常：0xC000041D：在用户回调期间遇到未处理的异常。
如果我更改此
D3D11CreateDeviceAndSwapChain
（
NULL，
D3D_DRIVER_TYPE_HARDWARE，
NULL，
NULL，
NULL，
NULL，
D3D11_SDK_VERSION，
& scd，
& swapChain，
& dev，
NULL，
& ; devcon
）;
这个
< pre lang =c ++> D3D11CreateDeviceAndSwapChain
（
NULL，
D3D_DRIVER_TYPE_REFERENCE，
NULL，
NULL，
NULL，
NULL，
D3D11_SDK_VERSION，
& scd，
& swapChain，
& amp; dev，
NULL，
& devcon
）;
它工作正常。 。
但是客户区是正常的。我的意思是它不是蓝色或类似于教程中的内容。它作为一个普通窗口着色..
我的代码有什么问题？或者我的硬件有什么问题吗？
提前致谢。

Hi.. Im beginner to DirectX programming..
And above is the code I've tried to implement a directX window..
But when I run it, it stops with an error.
It says
"Unhandled exception at 0x00EB167C in myprogram.exe: 0xC000041D: An unhandled exception was encountered during a user callback."
if I change this
D3D11CreateDeviceAndSwapChain
(
NULL,
D3D_DRIVER_TYPE_HARDWARE,
NULL,
NULL,
NULL,
NULL,
D3D11_SDK_VERSION,
&scd,
&swapChain,
&dev,
NULL,
&devcon
);
as this
D3D11CreateDeviceAndSwapChain
(
NULL,
D3D_DRIVER_TYPE_REFERENCE,
NULL,
NULL,
NULL,
NULL,
D3D11_SDK_VERSION,
&scd,
&swapChain,
&dev,
NULL,
&devcon
);
it works fine..
But the client area is normal. I mean it's not bluish or something like what's in the tutorial. It colored as a normal window..
What's the wrong with my code ? or is there anything wrong with my hardware ?
Thanks in advance.
