Gluing to the center of line

[JleruOHeP]

How can I make following type of glue?
I have dinamic connector (which can have many angles) and I want to glue another line to it. But that line must be glued exactly to the center of the connector - even if user changes that connector to straight line or adds few extra angles.

Graham Wideman mentioned in his book, that Visio trys to maintain the relative position of a ConnectionPoint on a dynamic connector. So you could draw a straight dynamic connector. Add a Connection Point to the middle. See if the point stays stable, after bending the connector arround.

It does seem to, that's a nice trick!

Yes, it works great, but the problem is that I cannot rule, when to add this connection - sometimes I have to add it when dynamic connector already heve few sections...

Found another tricky solution.
You can glue to Controls.TextPosition of the dinamic connector. It holds middle of the line until user moves text away from the line...
But what to do in that case still dont know...
