I was trying Windows API programming. In the tutorial the first prog was

#include <windows.h>

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {
MessageBox (NULL, "Hello World" , "Hello", 0);
return 0;
}

It was simply to check wether our compiler supported it or not. I was working in Visual Studio .net 2003.

I got this error when compiling
