窗体问题--拖动无标题栏的窗体

Private mouse_offset As Point

Private Sub form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseDown

mouse_offset = New Point(e.X, e.Y)

End Sub

Private Sub form1_MouseMove(ByVal Sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseMove

'按住鼠标左右键均可拖动窗体

Dim frm As Form1 = DirectCast(Sender, Form1)

If e.Button = MouseButtons.Left Or e.Button = MouseButtons.Right Then

Dim mousepos As Point = frm.MousePosition

'获得鼠标偏移量

mousePos.Offset(-mouse_offset.X, -mouse_offset.Y)

'设置窗体随鼠标一起移动

frm.Location = mousepos

End If

End Sub

Private Sub BtnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

'关闭窗体

Me.Close()

End Sub
