Error LNK2005 while building MFC application


I get following linker error several times for different methods while 
building a huge MFC solution:

"error LNK2005: "public: virtual struct CRuntimeClass * __thiscall 
CObject::GetRuntimeClass(void)const " 
(?GetRuntimeClass@CObject@@UBEPAUCRuntimeClass@@XZ) already defined in 
nafxcwd.lib(objcore.obj) nafxcw.lib TerminalSideApp"

How can I correct this?

Thanks in advance.

It looks as though you're linking both debug and release components
into the same program. Ensure that you're building either all release
or all debug projects.

Thanks, you are right, ignoring one of them solved related problem but the 
project stil has some link errors. Please take a look at my new post.

I have several documents that were generated by another program into a WordML format.

Writing Application "Drivers"
Greetings, I'm a long-time C++ developer, currently writing a C# Windows Forms application. I have a case where an application needs some functionality that varies depending on the current data. I know I could easily write different methods or even classes and then call the appropriate one, but I'm thinking more in terms of "plug ins" that can be written and called from my app. In C++, I might use DLLs for this. I could use LoadLibrary to load the appropriate "driver", the name of which could be a string that is part of my data. Any suggestio...

ActiveX ok in MFC but not in C#
Hello, I wrote an ActiveX in MFC. This ActiveX is derived from the interface IMyInterface and implement the standard functions QueryInterface, AddRef,Release and my own InCmde(BSTR Cmde,BSTR *Retour), OutCmde(BSTR Cmde,BSTR *Retour). The definition of this interface is in a separate idl file, I compile it with MIDL to obtain IMyInterface_h.h and IMyInterface_i.c . I do this, instead of integrated it in the ActiveX idl file, because I use this interface to many ACtiveX. The MFC application can take the pointer of this interface on two ActiveX and exchange it, so the two ActiveX can communica...

Application communicating with sensor via serialcomm.
I am trying to develop a SDI-application that communicates with a sensor. The application displays data that is received from a serial link. Sometimes this is very timeconsuming.

Should I make a class inherited from CWinThread to handle the comm, or shall i make a standard c++ class? How shall the GUI be updated? Via PostMessage? Via Events?

When I kill the process from TASK MANAGER, my prog's ExitInstance didn't get called. I want to do some cleanup. where should I put that cleanup code? Please help me Would it be presumptuous to ask why you have to kill your app using task manager rather than pushing the close button in the top right hand corner of the app?
