Hi, I was looking through some MSDN doc:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/com/htm/cmf_a2c_5iyg.asp there it's stated that: If neither concurrency model is specified by the dwCoInit parameter, the default is COINIT_MULTITHREADED. Does this mean we should change the way we interpret these flags (in compobj.c for example) because COINIT_MULTITHREADED equals 0 (which is a bit strange value for a flag)? The native QUARTZ.DDL calls CoInitializeEx with a COINIT of 4 which effectively has the COINIT_DISABLE_OLE1DDE and the COINIT_MULTITHREADED flags set. Shouldn't we have a check for COINIT_APARTMENTTHREADED and if this flag is not set we have to assume COINIT_MULTITHREADED? Especially because both these flags cannot be set at the same time (see mentioned MSDN doc). Cheers, Paul.
