网学网为广大网友收集整理了，图片按钮控件，希望对大家有所帮助！
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。
