Draw in EndScene

[nightUA]

I have almost no experience with directx. I want to draw a single triangle, but it fails. Device is cleared, also i can draw text, but any primitive fails. Im sure im missing some render states or my transforms are wrong.
Here is my code:

#define CUSTOMFVF (D3DFVF_XYZRHW | D3DFVF_DIFFUSE)
struct CUSTOMVERTEX
{
	FLOAT x, y, z, rhw;    // from the D3DFVF_XYZRHW flag
	DWORD color;    // from the D3DFVF_DIFFUSE flag
};
CUSTOMVERTEX OurVertices[] =
{
	{0.0f, 0.0f, 1.0f, 1.0f, D3DCOLOR_XRGB(0, 0, 255),},
	{0.0f, 100.0f, 1.0f, 1.0f, D3DCOLOR_XRGB(0, 255, 0),},
	{100.0f, 0.0f, 1.0f, 1.0f, D3DCOLOR_XRGB(255, 0, 0),},
};

LPDIRECT3DVERTEXBUFFER9 v_buffer;

void xD3::xD3Engine::Initialize(LPDIRECT3DDEVICE9 device)
{
	device->CreateVertexBuffer(3*sizeof(CUSTOMVERTEX),
		0,
		CUSTOMFVF,
		D3DPOOL_MANAGED,
		&v_buffer,
		NULL);

	VOID* pVoid;    // the void* we were talking about
	v_buffer->Lock(0, 0, (void**)&pVoid, 0);    // locks v_buffer, the buffer we made earlier
	memcpy(pVoid, OurVertices, sizeof(OurVertices));
	v_buffer->Unlock();    // unlock v_buffer
}

void xD3::xD3Engine::OnDraw(LPDIRECT3DDEVICE9 device)
{
	//device->GetTransform(D3DTS_WORLD, &matTranslate);
	device->SetFVF(CUSTOMFVF);
	device->SetRenderState(D3DRS_ZENABLE, FALSE);
	device->SetRenderState(D3DRS_LIGHTING, FALSE);
	device->SetRenderState(D3DRS_CULLMODE, D3DCULL_NONE);
	device->SetPixelShader(NULL);
	device->SetVertexShader(NULL);

	device->Clear(0,
		NULL,
		D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER,
		D3DCOLOR_XRGB(0,0,0),
		1.0f,
		0);

	D3DXMATRIX matTranslate;
	D3DXMatrixIdentity(&matTranslate);
	
	device->SetStreamSource(0, v_buffer, 0, sizeof(CUSTOMVERTEX));
	device->SetTransform(D3DTS_WORLD, &matTranslate);
	device->SetTransform(D3DTS_VIEW, &matTranslate);
	device->SetTransform(D3DTS_PROJECTION, &matTranslate);
	device->DrawPrimitive(D3DPT_TRIANGLELIST, 0, 1);

}

Any help please.
