The SelectObject function selects an object into the specified device context (DC). The new object replaces the previous object of the same type.
HGDIOBJ SelectObject( _In_ HDC hdc, _In_ HGDIOBJ hgdiobj );
- hdc [in]
- A handle to the DC.
- hgdiobj [in]

If the selected object is not a region and the function succeeds, the return value is a handle to the object being replaced. If the selected object is a region and the function succeeds, the return value is one of the following values.

|NULLREGION||Region is empty.|
If an error occurs and the selected object is not a region, the return value is NULL. Otherwise, it is HGDI_ERROR.
