I am having problems when I develop a application with work flow method. In this application, the user can drag and drop icons into a blank frame/region, and "link" these icons together. Then this application can generate and run codes automaticly, just like SAS/Enterprise Miner or SAS/Warehouse Administrator does.
I will start to overwrite the SAS/AF PFD class, however I have not enough information about PFD class at hand yet.
Can I get some advices/experience on overwritting the SAS/AF PFD class to get the work flow functionality?
