设置初始焦点 [英] setting the initial focus
问题描述
如何将初始焦点设置为控件（如图片框）？
假设我有一个带有单个图片框的表单。
当应用程序开始运行时，我想将焦点设置为
图片框，以便它可以响应KeyDown事件。
我试过将一个picBox.focus放在一个Form_load事件处理程序中但是没有
似乎有帮助。
有什么建议吗？
在此先感谢，

How does one set the initial focus to a control such as a picture box?
Suppose I have a form with a single picture box on it.
When the application starts to run I would like to set the focus to the
picture box so that it can respond to KeyDown events.
I tried placing a picBox.focus in a Form_load event handler but that didn''t
seem to help.
Any suggestions?
Thanks in advance,
Raja

图片框肯定没有KeyDown事件？

Surely the picturebox doesn''t have a KeyDown event?

将控件分配给最低的''TabIndex''，它将自动聚焦
。

Assign the control the lowest ''TabIndex'' and it will be focused
automatically.
