    Hello World

    I am wondering why this code won't compiler properly.
    Code:
    // Windows programming.cpp : Defines the entry point for the console application.
    //
    
    #include "stdafx.h"
    #include <windows.h>
    
    int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
    {
    	MessageBox(NULL, "Hello world!", "Sample", MB_OK);
    	return 0;
    }

    These are the errors I get.



    --------------------Configuration: Windows programming - Win32 Debug--------------------
    Linking...
    LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
    Debug/Windows programming.exe : fatal error LNK1120: 1 unresolved externals
    Error executing link.exe.

    Windows programming.exe - 2 error(s), 0 warning(s)


    I undefined _CONSOLE like the tutorial said to, but I still get those errors.

    I am using MCVC++.

    Now I get this

    Compiling resources...
    Compiling...
    Windows Tutorial.cpp
    c:\dxsdk\samples\c++\direct3d\windows tutorial\windows tutorial.cpp(9) : fatal error C1010: unexpected end of file while looking for precompiled header directive
    Error executing cl.exe.

    Windows Tutorial.exe - 1 error(s), 0 warning(s)

    Alright, I selected empty win32 project instead of the Hello WOrld and placed my code where it said to, and used their main() and everything else...guess thats what was wrong.

    This is the main() that I am now using.

    int APIENTRY WinMain(HINSTANCE hInstance,
    HINSTANCE hPrevInstance,
    LPSTR lpCmdLine,
    int nCmdShow)

    Hope this can at least help others with the same problem.

    project > propertys
    c/c++ > precompiles headers
    beside create/use precompiled header
    select Not Using Precompiled Headers
    this is for visual c.net

    I don't get it. How can this code work:

    Code:
    int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
    {
    	MessageBox(NULL, "Hello world!", "Sample", MB_OK);
    	return 0;
    }
    The function header doesn't have names for the parameters.
