Visual Basic 中的动态图片框 [英] Dynamic PictureBox in Visual Basic

问题描述

我已经创建了一个带有图片框的表单，并希望在程序运行时在表单上动态创建另一个图片框(在静态的左侧).我写了这段代码:

I've created a form with a PictureBox on it and would like to dynamically create another PictureBox on the form while the program runs (to the left of the static one). I've written this code:

Dim temp As PictureBox
temp = New PictureBox
temp.Image = StaticPictureBox.Image
temp.Visible = True
temp.Top = StaticPictureBox.Top
temp.Width = StaticPictureBox.Width
temp.Height = StaticPictureBox.Height
temp.Left = StaticPictureBox.Left - 20
temp.BringToFront()

当我运行此代码时，我可以检测到临时图片框确实已创建.但是，它不会呈现在表单上.它似乎在那里，但看不见.

When I run this code I can detect that the temp PictureBox does get created. However, it is not rendered onto the form. It seems like it's there but is invisible.

有人知道我做错了什么吗?

Does anyone have an idea of what I'm doing wrong?

推荐答案

需要将其添加到表单的控件集合中:

You need to add it to the form's control collection:

Me.Controls.Add(temp)
