Memory management of hDCs

Question

I've got an ID3DXFont (which is Direct3D9, by the way) which offers a method GetDC() which returns a handle to a device context (hDC). How is the memory for this value managed? MSDN doesn't mention anything about it and it doesn't provide it's own memory management like COM interfaces do.

Answer 1

You need to release that handle with ReleaseDC(HDC).

Answer 2

Can't you use SAFE_RELEASE macro on the handle?

Answer 3

I believe you have to call DeleteDC on the handle returned, when you are done with it. It was difficult to find much reference to this, with the exception of a comment made in this thread on gamedev.net.
