表格透明度 [英] Form transparency

问题描述

我正在使用visual basic中的第一个应用程序，我正在使用visual basic studio...我创建了一个带有按钮的表单 - 表单有一个带圆角的背景图像，我无法设置其颜色为透明"，因为出现以下错误:

I'm in progress with my first application in visual basic, and I'm using the visual basic studio... I have created a form, with buttons - form has an background image with rounded corners and I can not set its color to "transparent" because the following error occurs:

控件不支持透明背景色.

现在我不知道该怎么办.我已经读过我可以通过添加以下几行在代码中设置透明度:

Now I have no idea what to do. I have read that I can set the transparency in the code, by adding the following lines:

SetStyle(ControlStyles.SupportsTransparentBackColor, True)
Me.BackColor = Color.Transparent

但它似乎不起作用......那我还能做什么?

But it doesn't seem to work... So what else can I do?

完整代码:

Public Class Form1

  Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
    MsgBox("Test", 32, "Button Click")
  End Sub

  Private Sub Button2_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button2.Click
    Close()
  End Sub

  Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
    SetStyle(ControlStyles.SupportsTransparentBackColor, True)
    Me.BackColor = Color.Transparent
  End Sub

End Class

推荐答案

对于表单，试试这个:

Me.TransparencyKey = Me.BackColor

由于您有背景图片，请确保选择图片中未找到的背景颜色.

Since you have a background image, make sure to pick a BackColor that isn't found in the image.
