using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace MonitorControl
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public int WM_SYSCOMMAND = 0x0112;
public int SC_MONITORPOWER = 0xF170;
[DllImport("user32.dll")]
private static extern int SendMessage(int hWnd, int hMsg, int wParam,
int lParam);
private void button1_Click(object sender, EventArgs e)
{
SendMessage(this.Handle.ToInt32(), WM_SYSCOMMAND,
SC_MONITORPOWER, 2);
}
}
}
拖一个按钮控制项...加入 Click 事件...就 OK 了...:D
