Device Class

.NET Framework 2.0

The parent object of all graphical objects in the scene.

Namespace: Microsoft.WindowsMobile.DirectX.Direct3D
Assembly: Microsoft.WindowsMobile.DirectX (in microsoft.windowsmobile.directx.dll)

Syntax

C++

public class Device : IDisposable

public class Device implements IDisposable

JScript

public class Device implements IDisposable

Remarks

A device performs primitive-based rendering, creates resources, handles system-level variables, and gets and sets palettes.

Example

The following code example creates a device.

public class CreateDevice : Form
{
    // Our global variables for this project
    Device device = null; // Our rendering device

    public CreateDevice()
    {
        // Set the initial size of our form
        this.ClientSize = new System.Drawing.Size(400, 300);
        // And it's caption
        this.Text = "D3D Tutorial 01: CreateDevice";
    }

    public bool InitializeGraphics()
    {
        try
        {
            // Now let's setup our D3D stuff
            PresentParameters presentParams = new PresentParameters();
            presentParams.Windowed = true;
            presentParams.SwapEffect = SwapEffect.Discard;
            device = new Device(0, DeviceType.Default, this, CreateFlags.None, presentParams);
            return true;
        }
        catch (DirectXException)
        {
            return false;
        }
    }
    private void Render()
    {
        if (device == null)
            return;

        //Clear the backbuffer to a blue color 
        device.Clear(ClearFlags.Target, System.Drawing.Color.Blue, 1.0f, 0);
        //Begin the scene
        device.BeginScene();

        // Rendering of scene objects can happen here

        //End the scene
        device.EndScene();
        device.Present();
    }
    protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
    {
        this.Render(); // Render on painting
    }
    protected override void OnKeyPress(System.Windows.Forms.KeyPressEventArgs e)
    {
        if ((int)(byte)e.KeyChar == (int)System.Windows.Forms.Keys.Escape)
            this.Close(); // Esc was pressed
    }

        using (CreateDevice DeviceForm = new CreateDevice())
        {
            if (!DeviceForm.InitializeGraphics()) // Initialize Direct3D
            {
                MessageBox.Show("Could not initialize Direct3D.  This tutorial will exit.");
                return;
            }
            DeviceForm.Show();

            // While the form is still valid, render and process messages
            //while (DeviceForm.Created)
            //{
                DeviceForm.Render();
                Application.DoEvents();
            //}
        }
