How do I change the size of a picturebox when the app is run

I wrote a windows application, and I have a PictureBox on my form. Now, when 开发者_如何学GoI run my app, I want to give the resizing ability to my picture box in run time.

How can I do that?

Put the picture box in a container that allows resizing (for example, the split container, or a separate window) and dock to fill.
