Depends what it is. There are various macros beginning V_ that you might find useful. Say you have VARIANT v; HRESULT x = myobj.mycall(...,...,..., &v); You can have code like this: switch(V_VT(&v)) { case VT_BSTR: // Returned a string // V_BSTR(&v) is the BSTR being passed back... break; case VT_I4: // Returned a 'long' // V_I4(&v) is the number and so on. Does that help? Steve S
