| | | in my attempts at vb, i have succeeded in doing something rather of no value to my objective (a 3d Engine). That is to cause the whole form to the screen. I want to be able to have a 'viewscreen' that is where 3D material is located. I have utterly failed to get it to use a Picturebox over the mainform. It continously says "Object reference not set to an instance of an object" and the debugger points at my Class Name instead of a chunk of fixable code! Can anybody help me? I use vb.net almost exclusively but all i need is to be able to draw a triangle in a picturebox with vb.net. Once i do that i can use tons of other C# tutorials examples to build this! Please help! | |

| | Why do you not use "CustomVertex.PositionNormalColored" and create your vertices in 3D : vertices(0).Position = New Vector3(150, 100, 0) ?
I try to do that but it doesn't work.. :S
Can you give me the code for a Vector3 ?
thanks. | |

Imports Microsoft.DirectX
Imports Microsoft.DirectX.Direct3D
Public Class Form1
Private device As Direct3D.Device
I then get an error that reads " Direct3D.Device not defined"
ANy suggestions? | |

I too get the error that "Direct3D.Device is not defined" when using VS 2010 and the latest DirectX SDK.
I've got .Net Framework set to 3.5 and it's set to x86 for CPU. I'm running Windows 7 Ult x64 SP1 and I have a single ATI Radeon 5570 HD 1GB for graphics.
Perhaps my card isn't supported? Any Ideas on how to get passed this error? | |
