אהלן כולם,

הורדתי כמה דוגמאות של קודים שקשורים לDIRECTX וכשאני מנסה להריץ אותם יש לי כמה שגיאות

קוד לדוגמא:

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using Microsoft.DirectX;
using Microsoft.DirectX.Direct3D;

namespace Chapter1Code
{
	/// <summary>
	/// Summary description for Form1.
	/// </summary>
	public class Form1 : System.Windows.Forms.Form
	{
    private Device device = null;
		/// <summary>
		/// Required designer variable.
		/// </summary>
		private System.ComponentModel.Container components = null;
    private float angle = 0.0f;

		public Form1()
		{
			//

			//
			InitializeComponent();

      this.Size = new Size(800, 600);
      this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.Opaque, true);
		}

    /// <summary>
    /// We will initialize our graphics device here
    /// </summary>
    public void InitializeGraphics()
    {
      // Set our presentation parameters
      PresentParameters presentParams = new PresentParameters();

      presentParams.Windowed = true;
      presentParams.SwapEffect = SwapEffect.Discard;

      // Create our device
      device = new Device(0, DeviceType.Hardware, this, CreateFlags.SoftwareVertexProcessing, presentParams);
    }

    private void SetupCamera()
    {
      device.RenderState.CullMode = Cull.None;
      device.Transform.World = Matrix.RotationAxis(new Vector3(angle / ((float)Math.PI * 2.0f), angle / ((float)Math.PI * 4.0f), angle / ((float)Math.PI * 6.0f)), angle / (float)Math.PI);
      angle += 0.1f;

      device.Transform.Projection = Matrix.PerspectiveFovLH((float)Math.PI / 4, this.Width / this.Height, 1.0f, 100.0f);
      device.Transform.View = Matrix.LookAtLH(new Vector3(0,0, 5.0f), new Vector3(), new Vector3(0,1,0));
      device.RenderState.Lighting = true;
    }

    protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
    {
      device.Clear(ClearFlags.Target, System.Drawing.Color.CornflowerBlue, 1.0f, 0);

      SetupCamera();

      CustomVertex.PositionNormalColored[] verts = new CustomVertex.PositionNormalColored[3];
      verts[0].X = 0.0f; 
      verts[0].Y = 0.0f;
      verts[0].Z = 1.0f;
      verts[0].Normal = new Vector3(0.0f, 0.0f, -1.0f);
      verts[0].Color = System.Drawing.Color.White.ToArgb();
      verts[1].Position = new Vector3(-1.0f, -1.0f, 1.0f);
      verts[1].Normal = new Vector3(0.0f, 0.0f, -1.0f);
      verts[1].Color = System.Drawing.Color.White.ToArgb();
      verts[2].Position = new Vector3(1.0f, -1.0f, 1.0f);
      verts[2].Normal = new Vector3(0.0f, 0.0f, -1.0f);
      verts[2].Color = System.Drawing.Color.White.ToArgb();

      device.Lights[0].Type = LightType.Directional;
      device.Lights[0].Position = new Vector3();
      device.Lights[0].Diffuse = System.Drawing.Color.White;
      device.Lights[0].Attenuation0 = 0.2f;
      device.Lights[0].Range = 10000.0f;

      //device.Lights[0].Commit();
      device.Lights[0].Enabled = true;

      device.BeginScene();
      device.VertexFormat = CustomVertex.PositionNormalColored.Format;
      device.DrawUserPrimitives(PrimitiveType.TriangleList, 1, verts);
      device.EndScene();

      device.Present();

      this.Invalidate();
    }

		/// <summary>
		/// Clean up any resources being used.
		/// </summary>
		protected override void Dispose( bool disposing )
		{
			if( disposing )

		}

		#region Windows Form Designer generated code

    static void Main()

      using (Form1 frm = new Form1())
      {
        // Show our form and initialize our graphics engine
        frm.Show();
        frm.InitializeGraphics();
        Application.Run(frm);
      }
    }
	}
}

ואלה השגיאות:

Error	3	The type or namespace name 'DirectX' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)	D:\הורדות\טקסטים ושונות\C# Code\Chapter 1\Lights\Form1.cs	7	17	Lights

Error	4	The type or namespace name 'DirectX' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)	D:\הורדות\טקסטים ושונות\C# Code\Chapter 1\Lights\Form1.cs	8	17	Lights

Error	5	The type or namespace name 'Device' could not be found (are you missing a using directive or an assembly reference?)	D:\הורדות\טקסטים ושונות\C# Code\Chapter 1\Lights\Form1.cs	17	17	Lights

מה עושים?

תודה=]

א. שנה בבקשה את הכותרת של הת'רד לכותרת אינפורמטיבית יותר.

ב. אני מניח שאתה צריך להתקין את חבילת הפיתוח (SDK) של DirectX:

http://www.microsoft.com/downloads/details.aspx?familyid=86cf7fa2-e953-475c-abde-f016e4f7b61a&displaylang=en

א.שיניתי

ב. אני מקווה שזה יעזור

תודה=]

תתקין את הSDK האחרון(ספטמבר או אוגוסט 07, אני לא זוכר בידיוק).

תוסיף REFERENCE בתוך הפרוייקט עצמו לMicrosoft.DirectX ול Microsoft.DirectX.Direct3D.

תודה
