vb.net隐藏边框 vb怎么隐藏按钮

在VB.net中，Tabcontrol控件的边框怎么去掉？

你把 选项卡 拖到屏幕外面不就行了 只显示选项卡内东西 周围边缘都不要了 每个选项卡内配合labl 或按钮 标识不就行了。

跪求大神指点vb.net 怎么用api 在屏幕指定的位置 创建一个无边框的窗体呀?

我只会vb6.0

创建窗体用CreateWindiw函数，注册窗体用RegisterWndClass函数

也可以用setwindiwlong函数直接把一个现有的窗口边框去掉

VB.NET 如何去掉 GroupBox 控件的边框？

工程里面添加一个类，命名为myGroupBox，代码如下：

Imports System.ComponentModel

Imports System.Drawing.Drawing2D

Public Class myGroupBox

Inherits GroupBox

Public Sub New()

MyBase.BackColor = Color.Transparent

End Sub

Browsable(False) _

Public Overrides Property BackColor() As Color

Get

Return MyBase.BackColor

End Get

Set(value As Color)

MyBase.BackColor = value

End Set

End Property

Private m_backColor As Color = Color.Transparent

Public Property ActualBackColor() As Color

Get

Return Me.m_backColor

End Get

Set(value As Color)

Me.m_backColor = value

End Set

End Property

Protected Overrides Sub OnPaint(e As PaintEventArgs)

Dim tSize As Size = TextRenderer.MeasureText(Me.Text, Me.Font)

Dim borderRect As Rectangle = e.ClipRectangle

borderRect.Y += tSize.Height / 2

borderRect.Height -= tSize.Height / 2

Dim gPath As GraphicsPath = CreatePath(0, borderRect.Y, CSng(Me.Width - 1), borderRect.Height - 1, 5, True, _

True, True, True)

e.Graphics.FillPath(New SolidBrush(ActualBackColor), gPath)

e.Graphics.DrawPath(New Pen(Me.BackColor), gPath)

borderRect.X += 6

borderRect.Y -= 7

e.Graphics.DrawString(Me.Text, Me.Font, New SolidBrush(Me.ForeColor), borderRect)

End Sub

Public Function CreatePath(x As Single, y As Single, width As Single, height As Single, radius As Single, _

RoundTopLeft As Boolean, RoundTopRight As Boolean, RoundBottomRight As Boolean, RoundBottomLeft As Boolean) As GraphicsPath

Dim xw As Single = x + width

Dim yh As Single = y + height

Dim xwr As Single = xw - radius

Dim yhr As Single = yh - radius

Dim xr As Single = x + radius

Dim yr As Single = y + radius

Dim r2 As Single = radius * 2

Dim xwr2 As Single = xw - r2

Dim yhr2 As Single = yh - r2

Dim p As New GraphicsPath()

p.StartFigure()

'Top Left Corner

If RoundTopLeft Then

p.AddArc(x, y, r2, r2, 180, 90)

Else

p.AddLine(x, yr, x, y)

p.AddLine(x, y, xr, y)

End If

'Top Edge

p.AddLine(xr, y, xwr, y)

'Top Right Corner

If RoundTopRight Then

p.AddArc(xwr2, y, r2, r2, 270, 90)

Else

p.AddLine(xwr, y, xw, y)

p.AddLine(xw, y, xw, yr)

End If

'Right Edge

p.AddLine(xw, yr, xw, yhr)

'Bottom Right Corner

If RoundBottomRight Then

p.AddArc(xwr2, yhr2, r2, r2, 0, 90)

Else

p.AddLine(xw, yhr, xw, yh)

p.AddLine(xw, yh, xwr, yh)

End If

'Bottom Edge

p.AddLine(xwr, yh, xr, yh)

'Bottom Left Corner

If RoundBottomLeft Then

p.AddArc(x, yhr2, r2, r2, 90, 90)

Else

p.AddLine(xr, yh, x, yh)

p.AddLine(x, yh, x, yhr)

End If

'Left Edge

p.AddLine(x, yhr, x, yr)

p.CloseFigure()

Return p

End Function

End Class

工具栏会出现一个myGroupBox控件，放入窗体，你会发现边框没了。

vb.net 无边框窗体的问题

设置窗体的text为空，设置窗体的controlbox属性为false，设置窗体的FormBorderStyle 属性为Sizable，就可以改变窗体大小了，并且可以在任务栏点击。
