推荐答案

我不知道它在Basic中是怎么样的，但至少在C＃中，文本框提供了输入和'离开'事件。考虑将Enter-event中的BackColor设置为Red，并将Leave-event中的BackColor设置回原始颜色。

I don't exactly know how it is like in Basic, but at least in C# the textboxes provide an 'Enter' and a 'Leave' event. Consider setting the BackColor in the Enter-event to Red, and setting it in the Leave-event back to its original color.
