图片按钮：

思路：很简单，就是在一个picturebox控件上放置一个button控件，然后将这个button添加进picturebox上（确保先拖拽picturebox,后拖拽button）,设置这个button的背景色（这个时候是相对于picturebox）为透明。







Imports System.ComponentModel



Public Class picturebutton



Inherits System.Windows.Forms.UserControl







#Region " Windows 窗体设计器生成的代码 "















'UserControl 重写 dispose 以清理组件列表。



Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)



If disposing Then



If Not (components Is Nothing) Then



components.Dispose()



End If



End If



MyBase.Dispose(disposing)



End Sub







'Windows 窗体设计器所必需的



Private components As System.ComponentModel.IContainer

'可以使用 Windows 窗体设计器修改此过程。



'不要使用代码编辑器修改它。
