触摸屏浏览器—Windows中改变显示器的分辨率和刷新频率

在windows下要实现不同用户拥有不同分辨率其实可以自己动手来实现

首先制作一个能改变屏幕分辨率的C#程序，源代码如下，使用了VS2005

1、新建Windows Application工程，取名为分辨率
2、粘贴各文件的代码：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

using System.Runtime.InteropServices;
namespace 分辨率
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        public enum DMDO
        {
            DEFAULT = 0,
            D90 = 1,
            D180 = 2,
            D270 = 3
        }

        [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
        struct DEVMODE
        {
            public const int DM_DISPLAYFREQUENCY = 0x400000;
            public const int DM_PELSWIDTH = 0x80000;
            public const int DM_PELSHEIGHT = 0x100000;
            private const int CCHDEVICENAME = 32;
            private const int CCHFORMNAME = 32;

            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = CCHDEVICENAME)]
            public string dmDeviceName;
            public short dmSpecVersion;
            public short dmDriverVersion;
            public short dmSize;
            public short dmDriverExtra;
            public int dmFields;

            public int dmPositionX;
            public int dmPositionY;
            public DMDO dmDisplayOrientation;
            public int dmDisplayFixedOutput;

            public short dmColor;
            public short dmDuplex;
            public short dmYResolution;
            public short dmTTOption;
            public short dmCollate;
            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = CCHFORMNAME)]
            public string dmFormName;
            public short dmLogPixels;
            public int dmBitsPerPel;
            public int dmPelsWidth;
            public int dmPelsHeight;
            public int dmDisplayFlags;
            public int dmDisplayFrequency;
            public int dmICMMethod;
            public int dmICMIntent;
            public int dmMediaType;
            public int dmDitherType;
            public int dmReserved1;
            public int dmReserved2;
            public int dmPanningWidth;
            public int dmPanningHeight;
        }

[DllImport("user32.dll", CharSet = CharSet.Auto)]
//static extern int ChangeDisplaySettings( DEVMODE lpDevMode, int dwFlags);

static extern int ChangeDisplaySettings([In] ref DEVMODE lpDevMode, int dwFlags);

void ChangeRes()
{

            Form1 t = new Form1();
            long RetVal = 0;
            DEVMODE dm = new DEVMODE();
            dm.dmSize = (short)Marshal.SizeOf(typeof(DEVMODE));
            dm.dmPelsWidth = 1024;
            dm.dmPelsHeight = 768;
            dm.dmDisplayFrequency = 85;
            dm.dmFields = DEVMODE.DM_PELSWIDTH | DEVMODE.DM_PELSHEIGHT | DEVMODE.DM_DISPLAYFREQUENCY;
            RetVal = ChangeDisplaySettings(ref dm, 0);
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            ChangeRes();
        }

}
}
