I have standalone programs written in VB.NET, and I was wondering if they will need to be edited when we get Teamcenter PDM?  I am not completely familiar with a PDM, so I'm wondering if opening files through API will be the same, or if I'll actually have to write code to connect to the Teamcenter PDM to check parts in and out, and getting write access?  Will there be a Software Developer Kit I'll need to download to get the APIs to work with the PDM?  Any information on how programming with a PDM differs would greatly be appreciated.  Thanks!
