im getting this tutorial:
http://einfall.blogspot.com/2005/02/using-directx-and-c-sharp-to-create.html

and i got some error, i dont know how to fix it.

Can someone help?

i use visual c# express 2008, latest runtime and latest directx


using System;
using System.Drawing;
using System.Windows.Forms;
using Microsoft.DirectX;
using Microsoft.DirectX.Direct3D;

namespace VerticesTutorial
{
public class example : Form
{
Device device = null;
VertexBuffer vertexBuffer = null;

static void Main()
{
example form = new example(); //<= this is where i get error message
form.InitializeGraphics();
form.Show();
while (form.Created)
{
//Update our game, and render to screen
form.Render();
Application.DoEvents(); //Let the OS handle what it needs to
}
}

private void Render()
{
if (device == null)
return;
device.Clear(ClearFlags.Target, System.Drawing.Color.Blue, 1.0f, 0);

device.BeginScene();

device.SetStreamSource(0, vertexBuffer, 0);
device.VertexFormat = CustomVertex.TransformedColored.Format;
device.DrawPrimitives(PrimitiveType.TriangleList, 0, 1);

device.EndScene();
device.Present();
}



public void 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.Hardware,
this,
CreateFlags.HardwareVertexProcessing,
presentParams);

device.DeviceReset +=
new System.EventHandler(this.OnResetDevice);
this.OnResetDevice(device, null);
}
catch (DirectXException e)
{
MessageBox.Show(null, "Error intializing graphics: " +
e.Message, "Error");
Close();
}
}

public void OnResetDevice(object sender, EventArgs e)
{
Device dev = (Device)sender;
vertexBuffer
= new VertexBuffer(typeof(CustomVertex.TransformedColored),
3,
dev,
0,
CustomVertex.TransformedColored.Format,
Pool.Default);

GraphicsStream stm = vertexBuffer.Lock(0, 0, 0);
CustomVertex.TransformedColored[] verts =
new CustomVertex.TransformedColored[3];

verts[0].X = 150;
verts[0].Y = 50;
verts[0].Z = 0.5f;
verts[0].Rhw = 1;
verts[0].Color = System.Drawing.Color.Aqua.ToArgb();
verts[1].X = 250;
verts[1].Y = 250;
verts[1].Z = 0.5f;
verts[1].Rhw = 1;
verts[1].Color = System.Drawing.Color.Brown.ToArgb();
verts[2].X = 50;
verts[2].Y = 250;
verts[2].Z = 0.5f;
verts[2].Rhw = 1;
verts[2].Color = System.Drawing.Color.LightPink.ToArgb();
stm.Write(verts);
vertexBuffer.Unlock();
}
}

What error do you get, exactly? How did you configure the project this
code is being compiled in? What's the target type?

Are you referencing the DirectX libraries?
But really as Pete says, unless you tell us the error it's very hard
to suggest what your problem might be.

Yes i reference directx.

I get

Unhandled Exception: System.BadImageFormatException: is not valid Win32
application. (Exception from HRESULT: 0x800700c1)
at VerticesTutorial.example.InitializeGraphics()
at VerticesTutorial.example.Main() in Aform.cs:line 18

im new to c# and visual studio so for project configure i dont know what you
mean. i just use empty project.

What OS are you running this on? When running on a 64-bit os, you'll have to
change the target platform "MSIL" into "X86" in your project properties.
DirectX can only be used from 32-bit applications, so it's better to set the
target platform to "X86" even when running on a 32-bit OS.

x64 is os. can you tell me exactly where can i change MSIL? im new to visual studio?

thanks!

Project menu -> project Properties -> Build tab - Platform target "Any CPU"
select "X86" from the dropdown, rebuild the project when done.
