vb.net无边框窗体 vbnet窗体设计

如何移动VB中的无边框窗体

1、无边框窗体也就是无标题栏窗体，对于这样的窗体移动需要编程实现。

2、vb有两种办法实现，一直接编程实现，二调用windows API编程实现。

3、这里示例直接编程实现：

Option Explicit

Dim BolIsMove As Boolean, MousX As Long, MousY As Long

Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)

If Button = 1 Then BolIsMove = True

MousX = X

MousY = Y

End Sub

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)

Dim CurrX As Long, CurrY As Long

If BolIsMove Then

CurrX = Me.Left - MousX + X

CurrY = Me.Top - MousY + Y

Me.Move CurrX, CurrY

End If

End Sub

Private Sub Form_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)

BolIsMove = False

End Sub

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);

}

}

Vb.net 无边框窗体如何实现四周阴影？ 网上搜到的都是两边阴影的，我需要四周阴影

设置全局变量：

Dim drag As Boolean

Dim mousex As Integer

Dim mousey As Integer

假设你想拖动的是Panel1控件，以及此控件上的 Label1（用于显示标题）和PictureBox4（用于显示图标）：

Private Sub TitleMove_MouseDown(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseDown, Label1.MouseDown, PictureBox4.MouseDown

drag = True

mousex = Windows.Forms.Cursor.Position.X - Me.Left

mousey = Windows.Forms.Cursor.Position.Y - Me.Top

End Sub

Private Sub TitleMove_MouseMove(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseMove, Label1.MouseMove, PictureBox4.MouseMove

If drag Then

Me.Top = Windows.Forms.Cursor.Position.Y - mousey

Me.Left = Windows.Forms.Cursor.Position.X - mousex

End If

End Sub

Private Sub TitleMove_MouseUp(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseUp, Label1.MouseUp, PictureBox4.MouseUp

drag = False

End Sub
