[gpshadrach]

hi friends i have created one object called pIImage. I have to give the object pIImage as A argument to AddImage(). IN VARIANT type. how to convert one object to VARIANT type :sigh: eg. hr = CoCreateInstance(CLSID_Image,NULL,CLSCTX_INPROC_SERVER,IID_IImage,(void **)&pIImage); pDoc->AddImage(pIImage) error C2664: 'AddImage' : cannot convert parameter 1 from 'struct XYZ5::IImage *' to 'struct tagVARIANT' Shadrach

If you look more closely at VARIANT constructors (more precisely, at _variant_t, you'll notice that one of them accepts IUnknown* and bool arguments. This is exactly what you need:

pDoc->AddImage(_variant_t(pIImage, true));
