请问下面这段程序怎么编译？

[icelover]

这是FENG YUAN 的Windows Graphics Programming Win32 GDI and DirectDraw书上第一章的一个例子
#define STRICT
#define WIN32_LEAN_AND_MEAN

#include <windows.h>
#include <tchar.h>
#include <assert.h>

void CenterText(HDC hdc, int x,int y, LPCTSTR szFace,
LPCTSTR szMessage,int point)
{
HFONT hFont = CreateFont(
-point * GetDeviceCaps(hdc,LOGPIXELSX) / 72,
0,0,0,FW_BOLD,TRUE,FALSE,FALSE,
ANSI_CHARSET,OUT_TT_PRECIS,CLIP_DEFAULT_PRECIS,
PROOF_QUALITY,VARIABLE_PITCH,szFace);
assert(hFont);

HGDIOBJ hOld = SelectObject(hdc,hFont);

SetTextAlign(hdc,TA_CENTER | TA_BASELINE);

SetBkMode(hdc,TRANSPARENT);
SetTextColor(hdc,RGB(0,0,0xFF));
TextOut(hdc,x,y,szMessage,_tcslen(szMessage));
SelectObject(hdc,hOld);
DeleteObject(hFont);
}

const TCHAR szMessage[] = _T("hello,world");
const TCHAR szFace[] = _T("Times New Roman");

#pragma comment(linker,"-merge:.rdata=.text")
#pragma comment(linker,"-align:512");

extern "C" void WinMainCRTStartup()
{
HDC hDC = GetDC(NULL);
assert(hDC);

CenterText(hDC,GetSystemMetrics(SM_CXSCREEN)/2,
GetSystemMetrics(SM_CYSCREEN)/2,
szFace,szMessage,72);

ReleaseDC(NULL,hDC);
ExitProcess(0);
}
编译的时候说unresolved external symbol _main referenced in function _mainCRTStartup
请问应该在Project settings里面做什么样的设置才能编译通过?

把project->setting ->link 下面的文本框里的system:console改syetem:window,可能书写有误,大致意思差不多.

[icelover]

你指的是subsystem:windows吧？
这个好像默认(建立一个空的win32 project）就是subsystem:windows啊

这种垃圾书就不要看了

[步履人生]

you must create a Main()function first, and put all of the codes into a .cpp file,

and then you can use c++ compiler to compile it.

use vc++ is ok for this.
