要做无边框窗体，窗口四边有黑色直线、可拖动、不遮挡任务栏，这怎么做的出来？

两种方法可做到
1、xaml+vb.net
2、winform+vb.net
具体代码拼写忘的差不多了，到家给你找找

或者加我QQ也行1045135632

先说第一种方法,建立一个WPF窗体,将window1的属性中添加
Windowstyle="None" AllowsTransparency="True" Background="Transparent"
这三个属性,置于边框可以用PS做一个效果底图,将Background设置为底图就可以了
第二种方法是使用WinForm窗体,将form1的FormBorderStyle属性设置为none,窗体拖动是用如下代码:
Private oOriginalRegion As Region = Nothing
　' 用于窗体移动
　Private bFormDragging As Boolean = False
　　Private oPointClicked As Point
Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As
System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseDown
　　Me.bFormDragging = True
　　Me.oPointClicked = New Point(e.X, e.Y)
　　End Sub
　Private Sub Form1_MouseUp(ByVal sender As Object, ByVal e As
System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseUp
　　Me.bFormDragging = False
　　End Sub
rivate Sub Form1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseMove
If Me.bFormDragging Then
Dim oMoveToPoint As Point
' 以当前鼠标位置为基础，找出目标位置
oMoveToPoint = Me.PointToScreen(New Point(e.X, e.Y))
' 根据开始位置作出调整
oMoveToPoint.Offset(Me.oPointClicked.X * -1, (Me.oPointClicked.Y + SystemInformation.CaptionHeight + SystemInformation.BorderSize.Height) * -1)
' 移动窗体
Me.Location = oMoveToPoint
End If
End Sub
WinForm的边框也是要自己做的,PS就可以了

@yu_jizhou 就类似于这个。

wpf拖动非常简单。直接在previewmousedown用dragmove
