问题描述

嗨〜我在我的电脑上运行了一个Microsoft Accelerator V2示例。当我在visual studio 2012中使用 DX9Targets 运行应用程序时，出现错误：无法创建DirectX 9设备。我的电脑有两块显卡，一块是Intel HD显卡4600，另外一块是NVIDIA GeForce GTX 765M。非常感谢！

Hi~I run a sample of Microsoft Accelerator V2 on my computer. when I run an applications using DX9Targets in visual studio 2012, a error shown up: Failure to create a DirectX 9 device. There are two graphics card in my computer,one is Intel HD graphics 4600, other one is NVIDIA GeForce GTX 765M. Thanks a lot!

using Microsoft.ParallelArrays;

    class Program
    {

            Random ranf = new Random();
            float[] inputArray1 = new float[arrayLength];
            float[] inputArray2 = new float[arrayLength];
            float[] stackedArray = new float[arrayLength];

            // [1]
            DX9Target evalTarget = new DX9Target();
            
            // [2]

            FPA fpInput1 = new FPA(inputArray1);

            FPA fpStacked = PA.Add(fpInput1, fpInput2);
            FPA fpOutput = PA.Divide(fpStacked, 2);

            // [5]
            stackedArray = evalTarget.ToArray1D(fpOutput);

            // [6]
            for (int i = 0; i < arrayLength; i++)
            {
                Console.WriteLine(stackedArray[i].ToString());
            }
        }
    }
