QuestionSimple Unresolved External Symbol error Pin

Hi,

I am wondering if anyone can help me out, i have created the following class and when i include it in another class it compiles fine, but when i try to create an object of it i get the following error:
1>Stocks.obj : error LNK2019: unresolved external symbol "public: __thiscall CStringParser::CStringParser(void)" (??0CStringParser@@QAE@XZ) referenced in function "public: __thiscall Stocks::Stocks(void)" (??0Stocks@@QAE@XZ)
1>Stocks.obj : error LNK2019: unresolved external symbol "public: __thiscall CStringParser::~CStringParser(void)" (??1CStringParser@@QAE@XZ) referenced in function "public: __thiscall Stocks::~Stocks(void)" (??1Stocks@@QAE@XZ)


In the file im calling this from i include the StringParser.h but still get this unresolved external symbol. Previously i have been including the .cpp files and it worked, but I want to learn how to do it properly using only header files. I am using Visual Studio 2008

Thanks in advance
