    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.



    int _stdcall WinMain(HINSTANCE i, HINSTANCE j, LPSTR k, int l)






    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,

    if(bind(lSock,(SOCKADDR *)&sockaddr,sizeof(SOCKADDR_IN))==SOCKET_ERROR)


    cerr<<"Bind socket failed!"<<endl;

  6. Create and Modify a CHM file says:

    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!
