Your question is really nice,
I think that you want your progressbar which is divided into sub parts?
Am I right?
I don't know any of this Code, but you can do one thing.
You can use Picturebox in the panel and create your own progressbar.
So this may be look differently from the original ones too,
If you want the same progressbar as VB.net in divided content then you can place those progressbar together, (I means: 1st progressbar end touches 2nd progressbar starting.
And if you think that this make the Progressbar with cutted lines then you can add the new big progressbar on it, and when the initial progressbar starts, hide the big progressbar,
I don't know if some one did it so before,
but this can be done.
Usually I do same thing at some places, i create the image with gradient fill and add to picture box so that it look nice,
So i just give idea from it. this idea was stuck by me, And i think that on your situation this can be done so...
In this Attachment I show how to do and so.
this is easy, I am unable to show with picture box now,
If you want to learn on picture box then msg me, I will do for it too...
