我刚刚尝试过你的建议，不幸的是它没有b $ b似乎也工作了。程序编译好了，行之前和之后都执行了，但这个特殊的

语句什么都不做。


感谢您的帮助。

1.哪里做你使用这个声明吗？


2.你想把焦点放在哪种控制上？

I''m in school, taking a VB .NET 2003 course, and the
teacher taught us how to use Sender.Focus() to return
focus to the control from which focus was received.

However, when I got home, and tried it on my own copy of
VB .NET 2003, it doesn''t seem to work, in fact the only
method that comes up with Intellisense is GetType. I
can''t find any information anywhere either in the MSDN
Library, or anywhere else for that matter. I was hoping
someone here could help me! I''m desperate!

I just tried your advice, and unfortunately it doesn''t
seem to work either. The program compiles fine, the line
before it and after it both execute, but this particular
statement does nothing.

Thank you for trying to help.

1. Where do you use this statement?

2. Which type of control do you want to set the focus to?
