hello, running: VC6 SP5 on WIN2K lastest SP calling CoCreateInstance() returns: error -2147221008 (0x800401f0 for you hex fans) The error is not the problem but rather that I cannot find what it means. MSDN Platform SDK states only three return values: REGDB_E_CLASSNOTREG -2147221164(0x80040154) CLASS_E_NOAGGREGATION -2147221232(0x80040110) and... S_OK 0L(I believe) if someone can retrieve or point me toward the COM error code page that contains this value (NOT the WIN32 error code as sometimes MS let''s OLE and WIN32 codes overlap) it would help much! Thank you in advance,

It seems that you have not called CoInitialize().
The error is named CO_E_NOTINITIALIZED.

What class are you trying to instantiate?

EDIT:
Would this be of any help?

YES, YES, YES!!!
THANK YOU, THANK YOU, THANK YOU!!!

Forgive my enthusiasm but what did you search for specifically because I hunted through my MSDN (v6a) and I got pissed off at the MSDN online (too much coffee today).

I was trying to grab an instance of a DxPlay8 iserver and I know I should have posted in the DirectX forum but I like this forum btr....

Thnx,

I grep'd the windows headers for the hex code.
The error is defined in winerror.h.

Glad i could help!

EDIT: Google found that link, based on the error name.
