Hi to all members.
Sorry for off-topic question, but I couldn’t find what HRESULT code means.
One program (not mine) calls CoCreateInstance() with CLSID_FilgraphManager
and IID_IGraphBuilder to use some DirectShow stuff (for playing movies). The
first call is successful, but the second one failes. And this fail is not
checked therefore the program crashes trying to use NULL interface pointer
(that is absolutely correct because CoCreateInstance failed).
I ran this program under debugger and that’s what I saw:
CoCreateInstance() returns error code 0x8007000 which I couldn’t decode and
NULL interface pointer.
So there’s my question: what does 0x8007000 code mean???
Many thanks in advance. I hope for your competent help.
WBR,

For these sort of questions, there are couple of very good COM/ATL discussion groups at :
http://discuss.develop.com
http://discuss.microsoft.com
HRESULT error codes are defined in winerror.h
Among these :
#define E_ACCESSDENIED HRESULT_TYPEDEF(0x80070005L)
#define E_OUTOFMEMORY HRESULT_TYPEDEF(0x8007000EL)

Scan the Win32 and DirectShow headers for this value.
