(Hope its not a problem me asking all these questions, hopefully this one isn't quite as simple as the last one)
Ok I'm trying to set up shaders for the first time. I'm getting a D3DERR_INVALIDCALL at this line:
_spriteEffect.SetValue("g_samSrcColor", _testSprite);
And this shader:

I checked that out and tried using "texture" and "Texture2D" and they both crash at
_spriteEffect = Effect.FromFile(_device, "shader.fx", ShaderFlags.None);
with an E_FAIL: Undetermined error occurred.
_spriteEffect = Effect.FromFile(_device, "shader.fx", ShaderFlags.None);
with an E_FAIL: Undetermined error occurred.

This is an invalid shader:

You need a texture to set from the CPU and a sampler to bind. You might want to look at how some of the shaders that use textures in the DirectX samples are written.

Ok sweet, this worked and didn't return any errors, but the effect doesn't get rendered.
Got the shader code from here
texture myTexture;sampler2D texSampler0 : TEXUNIT0 = sampler_state{ Texture = (myTexture); MIPFILTER = LINEAR; MAGFILTER = LINEAR; MINFILTER = LINEAR;};float4 MyShader( float2 Tex : TEXCOORD0 ) : COLOR0{ float4 Color; Color = tex2D( texSampler0, Tex.xy)*10; return Color;}technique TestShader{ pass p1 { VertexShader = null; PixelShader = compile ps_2_0 MyShader(); }} // Putting draw sprite here just for testing public void BeginScene() { _device.Clear(ClearFlags.Target | ClearFlags.ZBuffer, Color.Black, 1.0f, 0); _device.BeginScene(); _sprite.Begin(SpriteFlags.AlphaBlend | SpriteFlags.DoNotSaveState); _spriteEffect.Begin(FX.None); _spriteEffect.BeginPass(0); drawSprite(_testSprite, new Rectangle(32, 0, 32, 32), new Point(32, 32), Color.White); } /// <summary> /// Ends the scene /// </summary> public void EndScene() { _spriteEffect.EndPass(); _spriteEffect.End(); _sprite.End(); _device.EndScene(); }Got the shader code from here

Ok I did that and used Debug View and I get quite a bit of errors, unfortunately I don't know what to do about it. It says that "Total of 4 objects still alive" after I close the program. So I assume there are objects that need to be freed or cleaned up upon closing? Right now, my renderer has a Dispose method that calls _device.Dispose()

Ok, I fixed the errors by disposing the effet, the sprite, the texture, and the device. No more DX errors, but still no shader effect. Do I need to compile the shader or something?
EDIT: I also compiled my shader with the fxc.exe and it compiles fine.
