  • Hi,
    I am still Student and would like to know, if VC++ and Vc++.NET are thesame? I mean if I can compile, build etc, just normal things in C++, without web-comlications. I am asking it, becoase I noteced by using (VC++ 6) such std libs as <fstream> and <iostream> a lot of warning coming from the iplimentation of this libs, where is programming really "not cleer". Thanks a lot for your atencion!
    best regards

  • Hi all,

    I am a beginner to VC++. When I execute my first program to display a message window, I get the following linker error.

    Program:

    #include<windows.h>
    int _stdcall WinMain(HINSTANCE i, HINSTANCE j, LPSTR k, int l)
    {
    MessageBox(0,"Hi","Title",0);
    return(0);
    }

    Error:

    error LNK2001: unresolved external symbol _main
    fatal error LNK1120: 1 unresolved externals

    Looks like some settings need to be done in VC++ before starting off with programs. If so, please let me know the settings. I am unable to find it in any books.

    Thanks in advance,
    Ashok
  • Hi,
    I am a student in china and a beginer to c++,I got a problem when excuted linking of this programme:
    #include <stdlib.h>
    #include <iostream.h>
    #include <stdio.h>
    #include <winsock2.h>
    void main(int args,char** argv)
    {
    WSADATA data;
    SOCKET lSock,aSock;
    SOCKADDR_IN sockaddr;
    char c[]={"How are you!"};
    int length=12;
    int port=2000;

    if(WSAStartup(MAKEWORD(2,2),&data)!=0)
    {
    cerr<<"Load socket failed!"<<endl;
    exit(1);
    }

    lSock=socket(AF_INET,0,0);
    if(lSock==SOCKET_ERROR)
    {
    cerr<<"Create socket failed!"<<endl;
    exit(1);
    }

    sockaddr.sin_addr.s_addr=htonl(0);
    sockaddr.sin_family=AF_INET;
    sockaddr.sin_port=htons(port);

    if(bind(lSock,(SOCKADDR *)&sockaddr,sizeof(SOCKADDR_IN))==SOCKET_ERROR)
    {
    cerr<<"Bind socket failed!"<<endl;
    exit(1);
    }

    //The left of the programme was omitted,
    //all of that forms a Server Model applied
    //to the net.
    }
    When I compile the programme, There is no
    wrong,but linked,The error message printed
    in the output window like this:
    error LNK2001: unresolved external symbol
    (such as _closesocket@6,...,_socket@12,_WSAStartup)

    I try my best to solve the problem but failed,
    I am grateful to your help.and my email is

  • I am working on a project. I have to convert some files ( perhaps HTML,MHTML,Doc,Txt etc.) into a single CHM,and also, the User can reload the CHM that had been generated for some modification. I don't even konw how to make and modify a CHM file using MFC. I am using Visual C++ 6.0. I hope some one could give a example. It could just cover only HTML2CHM and reload HTML from CHM for simple.

    Thank you very much!
