IDXGISwapChain1::GetHwnd method (dxgi1_2.h)
Retrieves the underlying HWND for this swap-chain object.
Syntax
HRESULT GetHwnd(
[out] HWND *pHwnd
);
Parameters
[out] pHwnd
A pointer to a variable that receives the HWND for the swap-chain object.
Return value
Returns S_OK if successful; an error code otherwise. For a list of error codes, see DXGI_ERROR.
If pHwnd receives NULL (that is, the swap chain is not HWND-based), GetHwnd returns DXGI_ERROR_INVALID_CALL.

Applications call the IDXGIFactory2::CreateSwapChainForHwnd method to create a swap chain that is associated with an HWND.
