Basic COM on CE type computers

[phobia1]

Hi
Could anyone tell me where I'm going wrong with my link to COM interfaces

HRESULT CoInitializeEX(NULL, COINIT_MULTITHREADED); //0

IClassFactory* pFactory = NULL;
CoGetClassObject(CLSID_FilterGraph,CLSCTX_ALL,NULL,IID_IClassFactory,(void **)&pFactory);
//clsid filtergarph is ok as is the IID_Classfactory but //cannot get pFactory to be valid pointer
pFactory->QueryInterface(IID_IMediaControl, (void **)&pMC);


Any ideas please
Best
Fred

Try to put something else instead of CLSCTX_ALL. For a exe is CLSCTX_LOCAL_SERVER but for dll CLSCTX_INPROC_SERVER. Also there could be some other parameters for remote servers. John Fill

Have found the answer to be unregistration of CLSID
