I checked VML for project reasons and wrote a prototype of Web workflow designer!

In the new company, the first task is that the customer needs a simple web graphics tool, which is really a Bt requirement. But there is no way .. I have heard that VML is powerful, so I decided to use VML. I felt that I had some experiences. As a result, I wrote a Web workflow designer in my spare time.
Of course, this is just a simple prototype. The following features are not completed.
1. No persons can participate in the action.
2. Set the flow direction conditions.
3. Converts the design results to structured data for storage.

If someone is interested in this, I think I will improve these functions. Or you can expand it yourself. These are not big issues.
 
It mainly uses three VML objects. Line, group, roundrect.
Here is the run:

Test environment: IE7 (WINXP). IE6 (win2003)
If it is published to the IIS directory for running, it can be directly run at IE Security Level-high.
If you are running as a local file, you may need to allow ActiveX to run.
Right mouse and keyboard for operation!
I hope to help you.
