the following code is copied out of the Delphi headerfile defining the
// flags passed as the coInit parameter to CoInitializeEx.
COINIT_MULTITHREADED = 0; // OLE calls objects on any thread.
COINIT_APARTMENTTHREADED = 2; // Apartment model
COINIT_DISABLE_OLE1DDE = 4; // Dont use DDE for Ole1 support.
COINIT_SPEED_OVER_MEMORY = 8; // Trade memory for speed.
as you see, 0 has the meaning of COINIT_MULTITHREADED
You said you initialize also to NULL?
Maybe we both are doing the same?
