Building a GUI similar to graphedit

[William2005]

I would like to build a user interface that displays a workflow in the same way graphedit displays graphs (blocks with input and output connectors and arrows). Can any one give me an idea of how to get that kind of functionallity or better yet how microsoft did it? :)

ps. This application will be written in C# but I can read Delphi and C++ aswell.

Thanks in Advance

GraphEdit isn't a supersimple software like it looks like at first glance.

In the directshow sdk there are some code smaples though which also show such boxes IIRC, you might wanna take a look at it.

AVE Visual Editor connects Avisynth filters
same way like Graphedit. If you can read Basic
you'll find sources (http://forum.doom9.org/showthread.php?s=&threadid=75612) helpfull.
