Dim postion1 As New Point
mouse_event(H1 Or H8000, postion1.X * 65535 / 1366, postion1.Y * 65535 / 768, 0, 0)
'按绝对位置移动鼠标
'在鼠标坐标系统中，屏幕在水平和垂直方向上均匀分割成65535×65535个单元，
'当前所用显示屏分辨率为1366*768
'所以要进行如上转换
mouse_event(H2, 0, 0, 0, 0) '鼠标左键按下
mouse_event(H4, 0, 0, 0, 0) '鼠标左键弹起
msdn上有 mouse_event 的详解，大致使用如上
调用api
在Visual Baisc.net中的声明：
Declare Sub mouse_event Lib "user32" (ByVal dwFlags As Long, ByVal dx As Long, ByVal dy As Long, ByVal cButtons As Long, ByVal dwExtraInfo As Long)
Public Const MOUSEEVENTF_LEFTDOWN = H2 '模拟鼠标左键按下
Public Const MOUSEEVENTF_LEFTUP = H4 ’模拟鼠标左键释放
Public Const MOUSEEVENTF_MIDDLEDOWN = H20 '模拟鼠标中间键按下
Public Const MOUSEEVENTF_MIDDLEUP = H40 '模拟鼠标中间键释放
Public Const MOUSEEVENTF_RIGHTDOWN = H8 '模拟鼠标右键按下
Public Const MOUSEEVENTF_RIGHTUP = H10 '模拟鼠标右键释放
Public Const MOUSEEVENTF_MOVE = H1 '模拟鼠标指针移动
例：
mouse_event MOUSEEVENTF_LEFTDOWN,10,10,0,0
'在（10，10）模拟鼠标左键按下
1.在mouse事件中实现
2.调用windows API
实现方式为：
1.在mouse事件中实现
[csharp] view plain copy
Point mouseOff;//鼠标移动位置变量
bool leftFlag;//标签是否为左键
private void groupControl1_MouseUp(object sender, MouseEventArgs e)
{
if (leftFlag)
{
leftFlag = false;//释放鼠标后标注为false;
}
}
private void groupControl1_MouseMove(object sender, MouseEventArgs e)
{
if (leftFlag)
{
Point mouseSet = Control.MousePosition;
mouseSet.Offset(mouseOff.X, mouseOff.Y); //设置移动后的位置
Location = mouseSet;
}
}
private void groupControl1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
mouseOff = new Point(-e.X, -e.Y); //得到变量的值
leftFlag = true; //点击左键按下时标注为true;
}
}
private void groupControl1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
mouseOff = new Point(-e.X, -e.Y); //得到变量的值
leftFlag = true; //点击左键按下时标注为true;
}
}
2.调用windows API
调用前需要添加using System.Runtime.InteropServices;
[csharp] view plain copy
[DllImport("user32.dll")]
public static extern bool ReleaseCapture();
[DllImport("user32.dll")]
public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);
private void groupControl1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
ReleaseCapture(); //释放鼠标捕捉
//发送左键点击的消息至该窗体(标题栏)
SendMessage(Handle, 0xA1, 0x02, 0);
}
}
