Windows下如何解决C ++中的以下问题 [英] How to resolve the follwing problem in c++ under windows

问题描述

#include "stdafx.h"
 #define WINVER 0x0500
#include <stdio.h>

#include <windows.h>
#include <conio.h>

int main(int argc, char* argv[])
{
    DEVMODE  dev;
     DWORD           DispNum = 0;
    DISPLAY_DEVICE  DisplayDevice;
    ZeroMemory(&DisplayDevice,sizeof(DisplayDevice));
EnumDisplayDevices(NULL, DispNum, &DisplayDevice, 0);

    return 0;
}

这是我的编码..

首先，它在EnumDisplayDevices中给出错误，未声明..
然后，我包含了#define WINVER 0x0500.
问题已经解决了.但是现在它又带来了一些其他时间上的错误..

错误:

this is my coding ..

first it gives error in EnumDisplayDevices is undeclared ..
Then i included #define WINVER 0x0500.
the problem is solved.. But now it gives some other compilie time errors..

Error:

Compiling...
disp.cpp
NOTE: WINVER has been defined as 0x0500 or greater which enables
Windows NT 5.0 and Windows 98 features. When these headers were released,
Windows NT 5.0 beta 1 and Windows 98 beta 2.1 were the current versions.
For this release when WINVER is defined as 0x0500 or greater, you can only
build beta or test applications.  To build a retail application,
set WINVER to 0x0400 or visit http://www.microsoft.com/msdn/sdk
to see if retail Windows NT 5.0 or Windows 98 headers are available.
See the SDK release notes for more information.
