I'm getting this message when I build my project - Linking... MyThread.obj : error LNK2001: unresolved external symbol "public: void __thiscall CMyThread::MyMessageHandler(unsigned int,long)" (?MyMessageHandler@CMyThread@@QAEXIJ@Z) E:\Stuff\Manmohan\Visual C++\IPM\Debug\IPM.exe : fatal error LNK1120: 1 unresolved externals My code is here :-

Your method implementation doesn't have the class name -

afx_msg void CMyThread::MyMessageHandler(WPARAM, LPARAM)
{
}

Perhaps you can try to delete the directory named "Debug" inside the directory named [your project] and build your project again.
