Im new to programming and i need help RRS feed

  • Question


       Hi im new to programing and i've chosen vb 2005 as my first language. Im reading an rpg development book in vb 2005 express edition, so i reached a part of the book where i get errors, the code is this(the highlighted lines are the errors):


    Imports System.Drawing
    Imports Microsoft.DirectX
    Imports Microsoft.DirectX.Direct3D

    Public Class Form1

        ' define some useful constants
        Dim PATH As String = System.Environment.CurrentDirectory()
        Const SCREENW As Integer = 800
        Const SCREENH As Integer = 600
        Dim BLACK As Integer = RGB(0, 0, 0)

        ' Direct3D objects
        Dim device As Direct3D.Device
        Dim backbuffer As Direct3D.Surface
        Dim sprite_handler As Direct3D.Sprite

        ' create image from a Direct3D surface
        Dim ocean As Direct3D.Texture
        Dim pirateship As Direct3D.Texture

        Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
            ' resize the form
            Me.Size = New Size(SCREENW, SCREENH)
            Me.Text = "Texture Loading Demo"
            Me.SetStyle(ControlStyles.AllPaintingInWmPaint Or ControlStyles.Opaque, True)

            ' get the desktop display mode
            Dim adapterNumber As Integer = Manager.Adapters.Default.Adapter
            Dim mode As DisplayMode = Manager.Adapters.Default.CurrentDisplayMode

            ' set up the presentation parameters
            Dim params As New PresentParameters
            params.Windowed = True
            params.SwapEffect = SwapEffect.Copy
            params.AutoDepthStencilFormat = DepthFormat.D16
            params.EnableAutoDepthStencil = True
            params.MultiSample = MultiSampleType.None
            params.BackBufferCount = 1
            params.BackBufferWidth = SCREENW
            params.BackBufferHeight = SCREENH

            ' check video card capabilities
            Dim flags As CreateFlags
            flags = CreateFlags.HardwareVertexProcessing
            flags += CreateFlags.PureDevice

            ' create the Direct3D device
            device = New Device(adapterNumber, DeviceType.Hardware, Me, flags, params)

            ' get reference to the back buffer
            backbuffer = device.GetBackBuffer(0, 0, BackBufferType.Mono)

            ' create the sprite handler
            sprite_handler = New Direct3D.Sprite(device)

            ' load the background as a texture
            ocean = TextureLoader.FromFile(device, "ocean.bmp")

            ' load the pirate ship
            pirateship = TextureLoader.FromFile(device, "pirateship.png")

        End Sub

        Sub draw_ocean()
            'demonstrate Direct3D.Sprite.Draw
            Dim rotation_center As New PointF(0, 0)
            Dim rotation_angle As Single = 0.0
            Dim position As New PointF(0, 0)

    sprite_handler.Draw2D(ocean, rotation_center, rotation_angle, position, Color.White)

        End Sub

        Sub draw_ship()
            'demonstrate Direct3D.Sprite.Draw2D
            Dim rotation_center As New PointF(48, 48)
            Dim rotation_angle As Single = 0.0
            Dim position As New PointF(300, 200)

    sprite_handler.Draw2D(pirateship, rotation_center, rotation_angle, position, Color.White)

        End Sub

        Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs)
            ' begin rendering

            ' clear the back buffer
            device.Clear(ClearFlags.Target + ClearFlags.ZBuffer, Color.Green, 1.0, 0)

            ' draw the sprites

            ' stop rendering

            ' copy back buffer to the screen
        End Sub

        Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
            ' check key code for ESC key
            If e.KeyCode = Keys.Escape Then

                ' destroy the Direct3D device

                ' destroy the images

                ' end the program
            End If
        End Sub

    End Class






    so, some guy told me that if i use a microsoft.directx.direct3D reference less than version 1.0.2908.0 then the Draw2D function isnt implamented. My microsoft.directx.direct3D Reference version is  1.0.2902.0 how do i make it 1.0.2908.0?


    i yet do not understand the code, as i said im new to this stuff. I'd really appreciate it if you would help me, ill reward you with free copy of game engine code once im finished.
