Remarks

GetHdc and ReleaseHdc are two methods that allow you to get and release the handle for a Windows-based device. You should always follow a call to GetHdc with a call to ReleaseHdc when you are finished with the Windows handle.

GetHdc is not designed to obtain handles created using Windows GDI methods such as CreateDC or CreateCompatibleDC.
