Im stuck on these errors. I know from paste experience that these errors usely mean I have a Lib wrong but none of these are related to a lib. WinMain.obj : error LNK2001: unresolved external symbol "public: virtual int __stdcall cApp::MsgProc(struct HWND__ *,unsigned int,unsigned int,long)" (?MsgProc@cApp@@UAGHPAUHWND__@@IIJ@Z) WinMain.obj : error LNK2001: unresolved external symbol "private: int __thiscall cApp::PlayerStateChange(struct sMessage *)" (?PlayerStateChange@cApp@@AAEHPAUsMessage@@@Z) WinMain.obj : error LNK2001: unresolved external symbol "private: int __thiscall cApp::RemovePlayer(struct sMessage *)" (?RemovePlayer@cApp@@AAEHPAUsMessage@@@Z) WinMain.obj : error LNK2001: unresolved external symbol "private: int __thiscall cApp::AddPlayer(struct sMessage *)" (?AddPlayer@cApp@@AAEHPAUsMessage@@@Z) WinMain.obj : error LNK2001: unresolved external symbol "private: int __thiscall cApp::PlayerInfo(struct sMessage *,unsigned long)" (?PlayerInfo@cApp@@AAEHPAUsMessage@@K@Z) WinMain.obj : error LNK2001: unresolved external symbol "private: int __thiscall cApp::PlayerID(struct sMessage *,unsigned long)" (?PlayerID@cApp@@AAEHPAUsMessage@@K@Z) WinMain.obj : error LNK2001: unresolved external symbol "private: int __thiscall cApp::SendNetworkMessage(void *,long,int)" (?SendNetworkMessage@cApp@@AAEHPAXJH@Z) WinMain.obj : error LNK2001: unresolved external symbol "private: int __thiscall cApp::CheckIntersect(class cMesh *,float,float,float,float,float,float)" (?CheckIntersect@cApp@@AAEHPAVcMesh@@MMMMMM@Z) Here my code that is being effected: *CODE REMOVED* [Edited by - Jim Adams on June 28, 2004 4:21:13 PM]

Where did you implement those functions? I don't see the code for them and nor does your compiler/linker.

Please don't post code that's copyrighted and non-distributable in source code form. *CODE REMOVED*

The problem is that you are declaring those functions in the cApp class declaration, but not providing the code for those functions in the cApp class. Make sure there's code for cApp::SendNetworkMessage, cApp::PlayerID, etc provided.

Just to make sure I'm not looking like a total jerk, the entire code blip was copied verbatim from my book. While I encourage readers to use the code, I really don't want it posted publicly.
