Rendering Primtives

[MedRamBO]

Hallo,

ich versuche seid einiger Zeit ein sipmles Rechteck in meinem directX 10 Fenster
zu rendern.
In directx 9 habe ich zuvor folgenden code verwendet:

#define D3DFVF ( D3DFVF_XYZRHW | D3DFVF_DIFFUSE )
struct vertex
{
	float x,y,z,rhw;
	DWORD dwColor;
};
DWORD _fvf;
IDirect3DPixelShader9* tempp;
IDirect3DVertexShader9* tempv;
HRESULT DrawPrimitiveLine( LPDIRECT3DDEVICE9 pDevice, float fromX, float fromY, float toX, float toY, DWORD dwColor )
{
	vertex fillline[2] = {
		{ (float)fromX, (float)fromY, 1.0f, 0.0f, dwColor},
		{ (float)toX, (float)toY, 1.0f, 0.0f, dwColor}
	};

	HRESULT iRet = S_OK;

	pDevice->GetFVF(&_fvf);
	pDevice->GetPixelShader(&tempp);
	pDevice->GetVertexShader(&tempv);

	pDevice->SetTexture(0, NULL);
	pDevice->SetPixelShader(NULL);
	pDevice->SetRenderState(D3DRS_CLIPPING,FALSE); 

	pDevice->SetFVF(D3DFVF);

	iRet = pDevice->DrawPrimitiveUP(D3DPT_LINESTRIP, 1, fillline, sizeof(vertex));

	pDevice->SetVertexShader(tempv);
	pDevice->SetPixelShader(tempp);
	pDevice->SetFVF(_fvf);

	return iRet;
}

Wie ihr seht brauche ich keine Pixelshader oder sonstige sachen. Ein simpler
code der halt nen Rechteck auf meinem Screenpositionen zeichnet. Kein 3d space oder so.

Ich hab jetzt versucht das selbe in directx 10 zu machen und hab dazu etwas auf
directxtutorial.com geschaut. Um ehrlich zu sein kann ich es nicht zum laufen bringen.
Es wird nichts angezeigt. Ein Sprite basierter code den ich gefunden hab, konnte ich auch
nicht zum laufen bringen.
Kann mir irgent jemand helfen das Rechteck zu zeichnen, oder findet Fehler in meinem code?

effect:

char szEffect[] = "struct DATA"
"{"
" float4 Pos : SV_POSITION;"
" float4 Color : COLOR;"
"};"

"DATA VS(float4 Pos : POSITION, float4 Col : COLOR)"
"{"
" DATA Data;"
" Data.Pos = Pos;"
" Data.Color = Col;"
" return Data;"
"}"

"float4 PS(DATA Data) : SV_TARGET"
"{"
" return Data.Color;"
"}"

"technique10 T0"
"{"
" pass P0"
" {"
" SetVertexShader(CompileShader(vs_4_0, VS()));"
" SetGeometryShader(NULL);"
" SetPixelShader(CompileShader(ps_4_0, PS()));"
" }"
"}";

drawing:

class DX10Draw {
public:
	private:
	//private data
	bool bInit;
	ID3D10Device* pDevice;
	
	public:
	//user functions
	void init(ID3D10Device* pDevice) {
		if(!bInit) {
			this->pDevice = pDevice;
			bInit = true;
		}
	}
	
	struct VERTEX {
		D3DXVECTOR3 Position;
		D3DXCOLOR Color;
	};
	
	void drawBox(TEXCOLOR texColor, int x, int y, int w, int h) {

		ID3D10EffectPass* pPass;
		D3D10_PASS_DESC PassDesc;
	
		pTechnique = pEffect->GetTechniqueByIndex(0);
		pPass = pTechnique->GetPassByIndex(0);
		pPass->GetDesc(&PassDesc);
	
		ID3D10InputLayout* pVertexLayout;
		pDevice->CreateInputLayout(inputLayout, 2, PassDesc.pIAInputSignature, PassDesc.IAInputSignatureSize, &pVertexLayout);
		//from what i have seen i need some effect file for this :S as this func wants some signature to a shader
	
		pDevice->IASetInputLayout(pVertexLayout);
		pDevice->IASetPrimitiveTopology(D3D10_PRIMITIVE_TOPOLOGY_T RIANGLELIST);
		UINT stride = sizeof(VERTEX);
		UINT offset = 0;
		pDevice->IASetVertexBuffers(0, 1, &pBuffer, &stride, &offset);
		pDevice->Draw(0, 6);
	}
};
DX10Draw dx10Draw;

Danke für jegliche Hilfe!!
