I have created an ATL application exe type where I am using to create
ATL component

QLView.obj : error LNK2005: _CLSID_MyAWrapper already defined in
jjjj.obj
SQLView.obj : error LNK2005: _LIBID_Project1Lib already defined in

Debug/jjjj.exe : fatal error LNK1169: one or more multiply defined

You have defined these variables in a header, then included this header
in more than one source file. Instead, you should declare in the header,
and define in exactly one source file.

With sufficient thrust, pigs fly just fine. However, this is not

land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
