Outline a box

I have posted this question before. But the suggestions given are not usable for my case :(
I have 10 frames, each frame have 2 option buttons in it.
When I tab to a new frame, I want a dotted rectangle to surround the frame. However, there is no gotfocus event for frames. I am a stuck at the moment, can anyone help me?

Basically, you don't have a gotfocus event for a frame because the frame can't have the focus. Instead, a control on the frame gets the focus. So you would put the dotted box code in the gotfocus event for the control instead.

I've attached an example program...
