Making a complete new project without the stdafx.cpp and stdafx.h file and with Not Using Precompiled Headers on, I get these errors:

test error LNK2005: _strcat already defined in ntdll.lib(ntdll.dll)

test error LNK2005: _atoi already defined in ntdll.lib(ntdll.dll)

test error LNK2019: unresolved external symbol "int __cdecl InjectDll(void *,char const *,int)" (?InjectDll@@YAHPAXPBDH@Z) referenced in function "void __stdcall ServiceMain(unsigned long,char * * const)" (?ServiceMain@@YGXKQAPAD@Z)

Can you help me with this better?
