Thank you.

I understand now.(providing a code snippet helped) Sorry, but I am still an english learner :)

Once again, a GraphicsDeviceManager is NOT a GraphicsDevice. The first parameter to the VertexDeclaration constructor is supposed to be a GraphicsDevice object, but you've passed a GraphicsDeviceManager object.

graphics.GraphicsDevice.VertexDeclaration = new VertexDeclaration(graphics.GraphicsDevice, VertexPositionColor.VertexElements);

Sorry, but when I readed this phrase "I'm pretty sure you have to replace "graphics.VertexDeclaration = " and the first argument to:" I tought that I have to delete VertexDeclaration and write graphics.GraphicsDevice instead.

Now I have

 graphics.GraphicsDevice.VertexDeclaration = new VertexDeclaration(graphics, VertexPositionColor.VertexElements);
            graphics.GraphicsDevice.DrawUserPrimitives(PrimitiveType.TriangleList, vertices, 0, 1);

But I still get a compiler error:

Error 1 The best overloaded method match for 'Microsoft.Xna.Framework.Graphics.VertexDeclaration.VertexDeclaration(Microsoft.Xna.Framework.Graphics.GraphicsDevice, Microsoft.Xna.Framework.Graphics.VertexElement[])' has some invalid arguments C:\Users\jan\Documents\Visual Studio 2005\Projects\WindowsGame1\WindowsGame1\Game1.cs 133 57 WindowsGame1

Same thing. The graphics variable is of type GraphicsDeviceManager. You need to access the GraphicsDevice member. e.g.:

graphics.GraphicsDevice.DrawUserPrimitives(...)

thanks.

What about graphics.DrawUserPrimitives ?

I'm pretty sure you have to replace "graphics.VertexDeclaration = " and the first argument to:

graphics.GraphicsDevice;

'Cause what is XNA gonna do with the thing that manages the graphics device? It wants the graphics device itself, thus: Graphics.GraphicsDevice;

Blah. I wanna pet the kitty.

Hello,

You probably remember me because of that stupid question ( DX10 on DX9 gpu).

Anyway I decided to try XNA (I am not a game developer so I think I dont need to know DX10 for beginning.

So I've learned some C# basics and started with XNA.
I have choosed "New game project" and I got the basic code and assembly configuration provided by C# Express. (very cool feature).

So, I folowed a tutorial (mostly) and edited code on style I like (variable names and spaccing).
Now when I try to compile I get a compiler error:

Error  1  'Microsoft.Xna.Framework.GraphicsDeviceManager' does not contain a definition for 'VertexDeclaration'  C:\Users\jan\Documents\Visual Studio 2005\Projects\WindowsGame1\WindowsGame1\Game1.cs  133  22  WindowsGame1
Error  2  The best overloaded method match for 'Microsoft.Xna.Framework.Graphics.VertexDeclaration.VertexDeclaration(Microsoft.Xna.Framework.Graphics.GraphicsDevice, Microsoft.Xna.Framework.Graphics.VertexElement[])' has some invalid arguments  C:\Users\jan\Documents\Visual Studio 2005\Projects\WindowsGame1\WindowsGame1\Game1.cs  133  42  WindowsGame1
Error  3  Argument '1': cannot convert from 'Microsoft.Xna.Framework.GraphicsDeviceManager' to 'Microsoft.Xna.Framework.Graphics.GraphicsDevice'  C:\Users\jan\Documents\Visual Studio 2005\Projects\WindowsGame1\WindowsGame1\Game1.cs  133  64  WindowsGame1
Error  4  'Microsoft.Xna.Framework.GraphicsDeviceManager' does not contain a definition for 'DrawUserPrimitives'  C:\Users\jan\Documents\Visual Studio 2005\Projects\WindowsGame1\WindowsGame1\Game1.cs  134  20  WindowsGame1

The following lines are underlined:

  graphics.VertexDeclaration = new VertexDeclaration(graphics, VertexPositionColor.VertexElements);
          graphics.DrawUserPrimitives(PrimitiveType.TriangleList, vertices, 0, 1);

Hope you guys can help me :)
