Thread: 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--------------------

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

I am using MCVC++.

Now I get this

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

Ohhh, wow...I turned them off and now the original code works! Thanks a lot!

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.

Oh, I didn't know that, sorry.
