  这是一个使用VB.net开发拖动无边框的窗体,以下为源代码,朋友们可以参考一下。



  '******************************************
  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
  '******************************************
  Private 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
