    I'm having a hard time making a .exe from a .cpp

    I have this .cpp file

    GigaSize.com: Host and Share your Files

    Which I downloaded from a site and edited on line (just added an if). I want to build it a generate a .exe, but I don't know exactly how. I have Visual Studio 2005 btw. If you can give me step by step instructions or just generate the .exe file for me I would really apreciate it.

    I didn't check the file or anything, but since you have the code done, all you have to do is compile it to create the executable.

    Yes, but I don't know how... I need to create a project on Visual Studio, right? I created an Empty Windows project, added the cpp to the source folder. The tried building it. I got some errors on the MessageBox calls, errors like this:

    error C2664: 'MessageBoxW' : cannot convert parameter 2 from 'const char [32]' to 'LPCWSTR'
    1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

    After that, I commented every call to MessageBox and got linking errors, like this one:

    1>eDNS.obj : error LNK2019: unresolved external symbol _WSAStartup@8 referenced in function _WinMain@16

    You should probably start with a "hello world", learn the basics of the language, learn the basics of Windows API and then try to compile that file (don't know what it contains, but it must be quite a big bite for a complete beginner).

    Anyway the error message indicates, that you are trying to compile a Unicode version of the program, but the source only allows it to be compiled as Ansi. (Source should be using const TCHAR [32] to support both.)

    Find where UNICODE is defined (I suppose in project settings somewhere) and remove it.

    (Edit, or actually the error is triggered by a single string literal, which should go inside a TEXT("literal") or T("literal") macro.)

    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.

    Great! Now I'm just stuck with the linking error, :P. Any help there?

    You know, you are not the first person with this problem. Why not copy the error message (relevant part) into Google's search box and see what it tells you?

    You need to link against some library.

    I'm looking for it. I can't find the solution. I don't understand many of the solutions either...

    I keep finding that I have to set the linker to use user32.lib, but that is done already. I can't figure this out.

    Yeah!!! I was missing wsock32.lib. To think I wrote a C++ VNC three years ago... And of course, I used WinSock. I can't rememember anything though

    And are you linking with the wsocket2 [I think that's the right name] library?
