HRESULT GetRunningClass(

LPCLSID lpClsid | //Pointer to an object’s CLSID
); |

Parameter

This method supports the standard return values E_INVALIDARG and E_UNEXPECTED, as well as the following:

Remarks

If an embedded document was created by an application that is not available on the user’s computer, the document, by a call to CoTreatAsClass, may be able to display itself for editing by emulating a class that is supported on the user’s machine. In this case, the CLSID returned by a call to IRunnableObject::GetRunningClass will be that of the class being emulated, rather than the document’s native class.
