hi mates; look at here at first : //stripdec.h #pragma once #ifndef ipaddressing_strIPdec #define ipaddressing_strIPdec #include "stdafx.h" using namespace std; using std::string; typedef unsigned long ulong; // strIPDec in order to deploying A.B.C.D strandard IP address from plain // string a.b.c.d namespace stripdec { class StrIPGet { public : StrIPGet();//constructor string get();//getting input string a.b.c.d void findindex();//finding index of each '.' in the string void setseg();//now we have A.B.C.D which each segemnt is in digit form. private: string _inputstr; short inpindex[3]; string segment[4]; }; class StrToDec { public: ulong conv(string& _segstr); }; } // #endif //////////////// //stripdec.cpp // strIPdec.cpp : Defines the entry point for the DLL application. // #include "stripdec.h" #include "stdafx.h" using namespace std; using namespace stripdec; BOOL APIENTRY DllMain( HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { return TRUE; } //start //------------------------------------------ string StrIPGet::get() { int count=0; do { getline(cin,_inputstr,' '); int j = _inputstr.find('.'); // While not at the end of the string: while(j != _inputstr.npos) { count++ //find the next '.' j = _inputstr.find('.', j); } if (count != 3)cout<<"invalid IP address ,try again."<<"\n"; } while (count != 3) //input is plain a.b.c.d along with error recovery. } //------------------------------------------ StrIPGet::StrIPGet() { inputstr.clear();//init...clearing an input string } //------------------------------------------ void StrIPGet::findindex() { for(j=0;j<=2;j++) { inpindex[j]=_inputstr.find('.',j); } } //------------------------------------------- void StrIPGet::setseg() { segment[0]=_inputstr.substr(0,inpindex[0]-0); segment[1]=_inputstr.substr(inpindex[0],inpindex[1]-inpindex[0]); segment[2]=_inputstr.substr(inpindex[1],inpindex[2]-inpindex[1]); segment[3]=_inputstr.substr(inpindex[2],input.end-inpindex[2]); } //------------------------------------------- ulong StrToDec::conv(string& _segstr) { return strtoul(_segstr); } errors : ///////////////////// e:\codes\IP_Addressing_solution\April11 ,2003\strIPdec\stripdec.cpp(25): error C2065: '_inputstr' : undeclared identifier e:\codes\IP_Addressing_solution\April11 ,2003\strIPdec\stripdec.cpp(26): error C2228: left of '.find' m

Probably in strIPdec.cpp you should have

#include "stdafx.h"
#include "stripdec.h"
