Hi! EveryOne!

I Am New To SlimDx..
Previously I Was Working On XNA!!

I Tried And Learned The 1st Two Tutorials Available On Slimdx.org
But Third One Always Gives Me This Error

Code Is Exactly The Same As In Third Tutorial

using (var bytecode = ShaderBytecode.CompileFromFile("Effect.fx", "VShader", "vs_4_0", ShaderFlags.None, EffectFlags.None))

                vertexShader = new VertexShader(device, bytecode);

Here Is Snapshot !

Effect.fx File Contains This

float4 VShader(float4 position : POSITION) : SV_POSITION

{

    return position;

}

float4 PShader(float4 position : SV_POSITION) : SV_Target

{

    return float4(1.0f, 1.0f, 0.0f, 1.0f);

}

I Need SlimDx For One Of My Projects!!

Any Help Would Be Great!!

Thanks!

There are many tools available for you to use to debug your application, such as PIX, the Direct3D debug runtimes, SlimDX error information, hell even a page of tips for you to follow. You're going to have to do some of the work on your own though, because scientists have yet to discover how to let people unlock their innate psychic debugging powers.

Erm, welcome to the forum.

Yup, as you can see, that exception is as helpful as "does not compute". At least create your device with DeviceCreationFlags.Debug and (hopefully) get some additional info. Mikes other hints apply, too, of course. If you then still can't figure out what's going wrong on your own, come back and tell us exactly what your tried and what info you collected. Currently I don't see anything blatantly done wrong yet, but it's really very little to work with.

And, I for one, rather prefer descriptions and (compilable) code than screenshots, screenshots can't be copy-pasted and show too little of the context. For communicating rendering artifacts, of course, screenshots are mostly better.

if i create device with DeviceCreationFlags.Debug it gives this error
Device.CreateWithSwapChain(DriverType.Hardware, DeviceCreationFlags.Debug, description, out device, out swapChain);
E_FAIL: An undetermined error occurred (-2147467259)

Is it something wrong with Device

I Have Pentium D!
Do'nt Have External Graphics Card.
I am Using Default VGA!

just i thought it might be?

Also Here Is Complete Filecode That i'm Trying To RUN!

As you have no 3d hardware, you could try using the software renderer - Drivertype.WARP

See http://www.gamedev.net/topic/569465-slimdx-initialise-direct3d101-with-warp-driver/

That code runs for me. I see a big yellow triangle

It's using shader model 4.0, that wont compile on your computer. You'll need to invest in a direct X 10 video card to get that code working. Buy a video card !

I have the exact problem discussed above.

I have, I believe, the latest versions of the DirectX SDK, C# Express and SlimDK. The laptop I am running on is a Sony running Windows7 with a DirectX 11 capable graphics board.

Things went silent on this thread back in November, and I am wondering if this means a solution to the problem has been found, or if everyone just got interested in other things.

Any help in solving this for me would be greatly appreciated. In fact, I would gladly pay someone to get on my machine with teamviewer and fix this for me.
