Line Control - Resizable/Movable at Runtime

[iPrank]

My project is similar to
JM's Manipulating GDI+ Drawings and NickThissen's Shape Editor. I haven't used their code though, I've written my own similar code. My shapes are custom controls.

All the shapes are working fine. But I'm having trouble with line control.

1. I've tried my own line control. But to resize/move I need to write separate code. The common code that works for all other shapes is not working.

2. I've tried VB Powerpack 3 Line Control,but moving/resizing it in runtime is too much complicated. It is NOT a real control. (I guess) It is directly drawn over a "ShapeContainer" control. So, i have to write custom code for this too.

Can anyone guide me how to do this for JM's code and/or NickThissen's code ? (Or any other idea)
(I'll PM them shortly.)

Thanks
