Error LNK 2019 problem

[Alex Cutovoi]

Hi fellows I'm using Visual C++ 2005 Express Edition and I'm getting some errors when I execute my app. This is my class that I defined in a ".h" file called "FloatText.h": #ifndef FLOATTEXT_H #define FLOATTEXT_H class FloatText { public: FloatText(); ~FloatText(); void SetText(char * cText); void MoveText(int iXPos, int iYPos); char * GetText(); private: float m_XPos, m_YPos, m_ZPos; double m_fModelviewMatrix[16]; double m_fProjectionMatrix[16]; int m_iViewportMatrix[4]; static int m_iTextObjects; char * m_cString; int m_iStringPos; }; #endif FLOATTEXT_H I implemented this class in a ".cpp" file, and include the "FloatText.h" in the "main.cpp" too. No problems until now. When I press CTRL+F5 these errors are shown to me: main.obj : error LNK2019: unresolved external symbol "public: char * __thiscall FloatText::GetText(void)" (?GetText@FloatText@@QAEPADXZ) referenced in function _WinMain@16 main.obj : error LNK2019: unresolved external symbol "public: void __thiscall FloatText::MoveText(int,int)" (?MoveText@FloatText@@QAEXHH@Z) referenced in function _WinMain@16 main.obj : error LNK2019: unresolved external symbol "public: __thiscall FloatText::FloatText(void)" (??0FloatText@@QAE@XZ) referenced in function _WinMain@16 main.obj : error LNK2019: unresolved external symbol "public: void __thiscall FloatText::SetText(char *)" (?SetText@FloatText@@QAEXPAD@Z) referenced in function "long __stdcall WindowProcedure(struct HWND__ *,unsigned int,unsigned int,long)" (?WindowProcedure@@YGJPAUHWND__@@IIJ@Z) So, what's going on if the code compilation runs normally??? thanks

the error came because you might havent implement the following functions GetText MoveText FloatText SetText in the cpp file or the way u implement wasnt correct. Check whether you have implemented the fu nction as shown below eg: char* **FloatText**::GetText() { return ......; }

Where is this cpp file. Is it included in the project.

Did you declare body for functions on the FloatText.cpp

Problem solved guys, I include the files in my project with the option, right clicking in my project and selecting "Add Existing Item". And works fine. thanks for the support
