I started to lean c++ and directx11 a few days back.
So I am no expert at it. .Please be kind enough to explain me why it had occurred ... I created the window and stuff correctly.Even the Swapchain initializtion proceeded as expected.But I am stuck at render Targetview Initializtion...
When ever i debug it gives me the following error
dxgiDevice 0x008959ac <Information not available, no symbols loaded for d3d11.dll> IDXGIDevice
I dont know what am I doing wrong here.I have included Static libraries(dxgi.lib d3dx11.lib d3d11.lib dxguid.lib D3DCompiler.lib) and linked correctly the header files and libraries as well..
The error seems to arise from this line
SwapChain->GetBuffer(0,__uuidof(ID3D11Texture2D),(LPVOID*)(&backBuffer));
I dont know what to do..It has gotten me really frustrated.
Please do help me out here..I will be very thank full
Thanks

The "error message" you're talking about comes from the VS debugger: all it is telling you is that it doesn't have any debugging symbols for d3d11.dll. In other words this is not your problem - it's a red herring.
To solve the problem, you need some error checking. IDXGISwapChain::GetBuffer returns a HRESULT, which you should check for errors, e.g.:
HRESULT res = SwapChain->GetBuffer(...);
if (!SUCCEEDED(res))
{
std::cerr << "Error getting buffer from swap chain: " << std::hex << res << std::endl;
}
You can then check the result against the values in this set of documentation to find out specifically what the error was.
Note that you should probably do similar things for a lot of your other DirectX calls as well.
