问题描述
我正在为我的视觉基础课程制作游戏.我有多个图片框，单击它们会分别显示隐藏的图像.游戏的重点是找到匹配的图片(很简单).
I'm making a game for my visual basic course. I have multiple picture boxes that when clicked will reveal a hidden image individually. The point of the game is to find the matching pictures (simple enough).
在最简单的级别上，我有 16 个图片框.图片框的数量随着难度的增加而增加.
On the easiest level, I have 16 picture boxes. The number of picture boxes increases as the difficulty increases.
对于每个图片框，我目前有一个事件处理程序如下(默认由visual studio创建):
For each picture box, I currently have an event handler as follows (default created by visual studio):
Private Sub pictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles pictureBox1.Click
里面，我打算用这个来改变图片框中的图片，如下:
Inside, I plan to use this to change the image in the picture box, as follows:
pictureBox1.Image = (My.Resources.picture_name)
我想知道是否有办法让一个 Sub 处理所有按钮点击，并更改适当的图片框，而不是使用 16 个单独的处理程序.例如:
I would like to know if there is a way to have one Sub handle ALL the button clicks, and change the appropriate picture box, instead of having 16 separate handlers. For example:
Private Sub pictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles pictureBox1.Click, pictureBox2.Click, pictureBox3.Click, ... pictureBox16.Click
然后执行以下操作:
' Change appropriate picture box
这是它的样子(目前):
Here's what it looks like (for now):
推荐答案
要找出点击了哪个 PictureBox，您只需查看 sender 变量.显然你必须将它从 Object 类型转换为 PictureBox 类型:
To find out which PictureBox was clicked you just have to look at the sender variable. Obviously you have to convert it from the Object type to the PictureBox type:
Dim ClickedBox As PictureBox
ClickedBox = CType(sender, PictureBox)
