    stdafx.h and const char* error

    I was creating a C program for creating Windows Socket, using Visual Studio 2010. I got the following errors while trying to compile it:

    1. error C1083: Cannot open include file: 'stdafx.h': No such file or directory [For the line, #include <stdafx.h>]

    2. IntelliSense: cannot open source file "stdafx.h" [For the line, #include <stdafx.h>]

    3. IntelliSense: a value of type "const char *" cannot be assigned to an entity of type "char" [For the line, buf[0] = " ";]

    How to fix those problems, I tried google and solved other 4 errors but these three are being headache for me, I have just started Win32 Application in C so I don't have deep knowledge. I am waiting for your help.

    Delete this line from your source file.

    Then navigate to something like project -> settings -> compiler -> pre-processor
    You're looking for a setting called "precompiled headers"
    When you find it, turn it OFF for both debug and release builds, then rebuild everything.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    I don't recommend Visual Studio for C programming, though. It lacks C90 support.
    GCC is an excellent compiler for C90. Code::Blocks can be used as an IDE for the compiler.

    Outside of your DOS world, your header file is meaningless.
