User drawing capability

[ferrad]

Can I do the following in VB? If so, what toolkit or controls do I need?

- the user must be able to draw a flowchart or flowsheet on a workspace using predefined objects or shapes and be able to link them together using lines or links;
- they must have the ability to double-click and right-click on these objects and links, and a dialog or popup menu respectively must appear;
- they must be able to drill down into each of these objects to expose yet another flowchart, if present;
- a pan and zoom feature would be useful;

This seems to specific to me, so I don't think there is a control that can do all this. But still, there is nothing you couldn't program yourself.
You only need to think about if you want to have a really good flicker free pan and accept programming a harder code, or just using shapeobjects, to realize it. Still the shapeobject has no events, so you would need to do this yourself in this case, too.
