How to customize the Track Bar in Visual Basic?

I have been trying to make an iPhone simulator in Microsoft Visual studio. In the iPhone, you get the 'Slide to unlock' Track bar (right?). I need to customize the slider of the 'TrackBar' features in Visual Basic.
Using a PictureBox and Line shape as a custom TrackBar is, too.
So, Can anyone please help me with this? Send the the code? Send me a link to a tutorial?
