CComVariant::ReadFromStream: Function does not take 2 arguments
in [Visual C]

From: NickP on 10 Jan 2007 06:45 Hi there, I am currently recieving a compiler error in atlcom.h on the following lines, Error 10 error C2660: 'ATL::CComVariant::ReadFromStream' : function does not take 2 arguments C:\Program Files\Microsoft Visual Studio 8\VC\atlmfc\include\atlcom.h 5969 Error 11 error C2660: 'ATL::CComVariant::WriteToStream' : function does not take 2 arguments C:\Program Files\Microsoft Visual Studio 8\VC\atlmfc\include\atlcom.h 6056 Error 12 error C2039: 'ClearToZero' : is not a member of 'ATL::CComVariant' C:\Program Files\Microsoft Visual Studio 8\VC\atlmfc\include\atlcom.h 6138 I can't for the life of me think what could be causing this all of a sudden. Although I have recently installed VS 2005 Service Pack 1 and this is the first time that I have attempted to compile this particular application since. Any ideas on how I can fix this? Are there 2 CComVariant objects? Nick.

Not unless your own code defines the second one. -- With best wishes, Igor Tandetnik With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead. -- RFC 1925
From: NickP on 10 Jan 2007 09:56 Hi Igor, As i said, it's in atlcom.h I haven't modifed any of the code in there... >> hr = var.ReadFromStream(pStm, pMap[i].vt); >> hr = var.WriteToStream(pStm, pMap[i].vt); >> var.ClearToZero(); Those are the 3 offending lines of code. Many thanks for your time and help. Nick.
