Hey, guys:
I want to Copy a ID3D10Texture2D surface to a HBitmap in dx10,but the function ID3D10Texture2D::Map returns an error of 0x80070057.I didn't know how to solve the problem,anyone can help me ?
The code:

ID3D10Texture2D* pBackBuffer = NULL;
HRESULT hRes = m_pSwapChain->GetBuffer( 0, __uuidof( ID3D10Texture2D ), ( LPVOID* )&pBackBuffer );
if (FAILED(hRes))
{
	DEBUG_ERR(( "DX10:GetFramePre:m_pSwapChain->GetBuffer Failed  0x%x" LOG_CR,hRes));
	return hRes;
}
DEBUG_MSG(( "DX10:GetFramePre:m_pSwapChain->GetBuffer OK " LOG_CR)); //Test OK

ID3D10Texture2D* pSurfTemp = NULL;

D3D10_TEXTURE2D_DESC desc;
ZeroMemory( &desc, sizeof(desc) );
desc.Width = frame.m_Size.cx;
desc.Height = frame.m_Size.cy;
desc.MipLevels = 1;
desc.ArraySize = 1;
desc.Format = s_bbFormat;
desc.SampleDesc.Count = 1;
desc.SampleDesc.Quality = 0;
desc.Usage = D3D10_USAGE_DEFAULT;
desc.BindFlags = D3D10_BIND_RENDER_TARGET | D3D10_BIND_SHADER_RESOURCE;
desc.CPUAccessFlags = 0;
desc.MiscFlags = 0;

hRes = m_pDevice->CreateTexture2D( &desc, NULL, &pSurfTemp );

if(FAILED(hRes))
{
	DEBUG_ERR(("DX10:GetFrame:m_pDevice->CreateTexture2D() Failed 0x%x" LOG_CR,hRes));
	return hRes;
}

m_pDevice->CopyResource(pSurfTemp,pBackBuffer); 

DEBUG_ERR(("DX10:GetFrame:m_pDevice->CopyResource() OK " LOG_CR));// Test OK

D3D10_MAPPED_TEXTURE2D ImageTemp;

hRes = pSurfTemp->Map( 0 , D3D10_MAP_READ, 0 ,&ImageTemp);//this returns an error;
if(FAILED(hRes))
{
	DEBUG_ERR(("DX10:GetFrame:pSurfTemp->Map Failed 0x%x" LOG_CR, hRes));
	return hRes;
}
DEBUG_MSG(("DX10:GetFrame:pSurfTemp->Map OK " LOG_CR));
