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

VB.NET模拟鼠标问题

Declare Sub mouse_event Lib "user32" Alias "mouse_event" (ByVal dwFlags As Integer, ByVal dx As Integer, ByVal dy As Integer, ByVal cButtons As Integer, ByVal dwExtraInfo As Integer)

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

VB.net怎样按住鼠标移动无边框窗体

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);

}

}

在VB.NET中有TextBox1_MouseClick和TextBox1_Click有区别么？除了鼠标还有什么可以进行点击呢

在TextBox1_MouseClick事件中可以获得鼠标的点击点（坐标），和鼠标是哪个键按下点击，TextBox1_Click虽然说也可接受鼠标的点击事件，但最主要是让软件可以模拟对TextBox1触发个点击事件，不用鼠标不用api，也没有点击的坐标和是是哪个键点击，只是触发个点击事件，也可以说是“没事找事”吧
