Problem with Texture and VertexBuffer in C#

[opaque]

Help.

I cannot get a background file to display properly in C# DirectX9 using a Vertex Buffer, Texture and TriangleList. This is supposed to be one of the simplest operations in DirectX and I have tried everything to get an image to display. It seems to be displaying only a very small portion of the image. What am I doing wrong?

Here is the code:

// check for, and specify, depth buffer
if (Microsoft.DirectX.Direct3D.Manager.CheckDepthStencilMatch(0,
Microsoft.DirectX.Direct3D.DeviceType.Hardware,

I'm just beginning here with managed dx, but when when I use TransformedTextured I must give 6 values for each for some reason (i copied from a tutorial)

x,y,z (never used), 1 (always 1),u,v

perhaps that will help you.

here's my tutorial adding a vertix


verts[i++] = new CustomVertex.TransformedTextured(
XPos + XSize, YPos, 0.5F, // Vertex position
1, // rhw (advanced)
1, 0); // texture coordinates

Thank you Rosecroix!!!! It worked

All I did was add the Rhw property as you suggested and assign 1 to it for each index ...

CustomVertex.TransformedTextured[] data =
new CustomVertex.TransformedTextured[4];
data[0].X = 0.0f;
data[0].Y = 0.0f;
data[0].Z = 0.0f;
data[0].Rhw = 1;
data[0].Tu = 0.0f;
data[0].Tv = 0.0f;
data[1].X = device.Viewport.Width;
data[1].Y = 0.0f;
data[1].Z = 0.0f;
data[1].Rhw = 1;
data[1].Tu = 1.0f;
data[1].Tv = 0.0f;
data[2].X = 0.0f;
data[2].Y = device.Viewport.Height;
data[2].Z = 0.0f;
data[2].Rhw = 1;
data[2].Tu = 0.0f;
data[2].Tv = 1.0f;
data[3].X = device.Viewport.Width;
data[3].Y = device.Viewport.Height;
data[3].Z = 0.0f;
data[3].Rhw = 1;
data[3].Tu = 1.0f;
data[3].Tv = 1.0f;
