如何在vb.net中将按钮更改为透明？ [英] How to change button as transparent in vb.net ?

问题描述

我正在开发Windows应用程序，我用移动选项动态创建按钮。实际上我有表单，因为我把面板与backroundimage作为Dock = Fill，在面板中我创建按钮动态地，我需要使按钮变得透明，即我需要通过动态创建的按钮来查看面板图像。因此需要使按钮成为透明的。

i我试试这个

  Dim  btn 作为 新按钮
 btn.Parent = 我 .ContainerSLD 
  Dim  buttonBackground 作为 新位图（btn.Width，btn.Height）
 使用 g  As  Graphics = Graphics.FromImage（buttonBackground）
 g.DrawImage（ Me  .ContainerSLD .BackgroundImage，新矩形（ 0 ， 0 ，buttonBackground.Width， buttonBackground.Height），btn.Bounds，GraphicsUnit.Pixel）
 结束 使用 
 btn.BackgroundImage = buttonBackground 
 

但它不会改变transparaent。

解决方案

只需将flatstyle设置为Flat ，背景颜色是否透明？

可能是



1.remove

 btn.BackgroundImage = buttonBackground 

2.write

 btn.BackColor = color.Transparent 

试试这个

Dim alpha AS Int16

alpha = 60

Button1.BackColor = Color.FromARGB（alpha，SystemColor.Control）

btn.BackgroundImage = buttonBackground

2.write

btn.BackColor=color.Transparent

try this
Dim alpha AS Int16
alpha = 60
Button1.BackColor = Color.FromARGB(alpha,SystemColor.Control)
