Question

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 System;
using Microsoft.ParallelArrays;
using FPA = Microsoft.ParallelArrays.FloatParallelArray;
using PA = Microsoft.ParallelArrays.ParallelArrays;
namespace AddArrays
class Program
static void Main(string[] args)
int arrayLength = 100;
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]
for (int i = 0; i < arrayLength; i++)
inputArray1[i] = (float)(Math.Sin((double)i / 10.0)
+ ranf.NextDouble() / 5.0);
inputArray2[i] = (float)(Math.Sin((double)i / 10.0)
+ ranf.NextDouble() / 5.0);
// [3]
FPA fpInput1 = new FPA(inputArray1);
FPA fpInput2 = new FPA(inputArray2);
// [4]
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());

Hello,
I'd ask in the
