For i = 1 To 7
If lb8.BackColor = Color.DimGray Then
If e.Form.Controls("Label" & i & "_1").BackColor = Color.DarkGray Then
e.Form.Controls("Label" & i & "_1").BackColor = Color.White

为什么这样我要求的是点击"Label8-1" 后 Label" & i & "_1 全部变色

hongye 发表于：2025/1/3 15:04:00当按下Label8-1后，Label8-1变色，所在的行 Label" & i & "_1变色
也就是当你按下Label8-1后，如果Label8-1的底色是透明色，那么Label8-1底色变成深灰色，字体变成浅灰色，而Label" & i & "_1不管之前是什么颜色，都会底色变成浅灰色，字体变成深灰色，反之那么Label8-1底色变成透明色，字体变成黑色，而Label" & i & "_1不管之前是什么颜色，都会底色变成白色，字体变成黑色

hongye 发表于：2025/1/3 15:42:00如何知道我有几个 e.Form.Controls("Label" & i & "_1")，，有时 e.Form.Controls("Label" & i & "_1") 的数量是不固定的

有点蓝 发表于：2025/1/3 15:44:00设计时考虑把【Label8-1】名称改为【Label8-1-7】,然后通过名称取最后的数字作为数量

hongye 发表于：2025/1/3 15:46:00Label8-1是固定的，Label" & i & "_1"是不固定的，但是最多也只是7
也就是图片里的1_1到7_7，不过只有少不会多
