Visual C++ Building error

water-man

I'm pretty new to programming and Visual C++ and am hoping someone here could point me in the right direction. I can get the program to compile ok, but then when I click the build button I get the following errors:

Linking...
1) Analysis.obj : error LNK2001: unresolved external symbol "protected: virtual struct AFX_MSGMAP const * __thiscall CAnalysis::GetMessageMap(void)const " (?GetMessageMap@CAnalysis@@MBEPBUAFX_MSGMAP@@XZ)

2) Analysis.obj : error LNK2001: unresolved external symbol "public: class CGuardianDoc * __thiscall CAnalysis::GetGuardianDoc(void)" (?GetGuardianDoc@

Questions I would like to konw are:
a) What do these mean?
b) Where should I start to look to find the solution?
c) possible causes of the error?

Some detail on what I'm trying to do:

I'm modifying a programme that displays graphs. I've modified the tool-bar to create a new menu. For this menu I've created a new class. This new class is to perform an analysis on some code that was initally written in C (which I have converted into C++ and got it to excute ok).

Any other info that I can provide please ask.

Thanks in advance,
Water-man (or woman??)

CAnalysis is a class you have written yourself ? Make sure it's included in the project. If it's from a library, make sure you have the library included in your linking options, or the easy way is to just add the library to the project.

The problem is that the compiler can't find the object implementation of the GetMessageMap and
GetGuardianDoc methods.

Yes. Thanks for your help.
