Alright, i'm using D3DX10CreateEffectFromFile and its returning E_FAIL. However the issue arises with the ID3D10Blob output on the function, its returning nothing. I don't know whether this means somethings wrong with the arguments I'm passing or that DirectX just really does not like me.

Here is the code if anyone can help.
Specific function where its called.

bool gShaderHandle::buildFX(LPCWSTR filename)
{
HRESULT hr = NULL;

ID3D10Blob* errorTwo = 0;

hr = D3DX10CreateEffectFromFile(filename,
  NULL,
	  NULL,
	  "fx_4_0",
	  D3D10_SHADER_DEBUG,
	  0,
	  device,
	  0,
	  0,
	  &gEffect,
	  &errorTwo,
	  0);

if(FAILED(hr))
{
if(errorTwo)
{
MessageBoxA(0, (char*)errorTwo->GetBufferPointer(), 0, 0);
errorTwo->Release();
}
}
gTech = gEffect->GetTechniqueByName("techPass");
return true;
}

Class its part of

class gShaderHandle
{
private:
ID3D10Effect* gEffect;
ID3D10EffectTechnique* gTech;
ID3D10InputLayout* gVertexLayout;
ID3D10Device* device;

public:
bool buildFX(LPCWSTR filename);
bool buildVertexLayouts();

ID3D10Effect* returnEffect();
ID3D10EffectTechnique* returnTech();

gShaderHandle(ID3D10Device* *device = NULL);
gShaderHandle(ID3D10Device* *device, bool WTF);

void modDevice(ID3D10Device* *d3ddevice);
};

Effect File

cbuffer cbPerObject
{
float4x4 gWVP;
};

void vs(float3 iPosL  : POSITION,
		float4 iColor : COLOR,
		out float4 oPosH  : SV_POSITION,
		out float4 oColor : COLOR)
{
oPosH = mul(float4(iPosL, 1.0f), gWVP);
	oColor = iColor;
}

float4 ps(float4 posH  : SV_POSITION,
		  float4 color : COLOR) : SV_Target
{
	return color;
}

technique10 techPass
{
	pass P0
	{
		SetVertexShader( CompileShader( vs_4_0, vs() ) );
		SetGeometryShader( NULL );
		SetPixelShader( CompileShader( ps_4_0, ps() ) );
	}
}

Make sure you create your device with the DEBUG flag enabled, and make sure that you link to d3dx10d.lib. If you do this, you will get detailed error messages in the debug output.

It is made with the DEBUG flag enabled and the d3dx10d.lib is linked. Still fails without placing a proper error message in ID3D10Blob.

Okay, fixed that issue ran into a whole new issue. Everything is running fine until I try to render a set of 8 cubes. Currently all that shows up are my FPS displays and camera displays. Nothing else. Massive dump of code incoming.

If any other parts are needed just let me know, Effect files info is already in the OP.

Once again already fixed, the sprite I was drawing text info to was messing with the viewport or covering up what I was rendering or something.
