I'm afraid the BDE implementation in Delphi XE3 is broken. The problem is not only with ftMemo fields, but any kind of a BLOB field (like ftGraphic). Here is a topic on Embarcadero Forums about the BDE, BLOB fields and Delphi XE3:
https://forums.embarcadero.com/thread.jspa?threadID=78430While I don't have a solution for getting the BDEDemoServer to work on Delphi XE3 without fixing the BDE units, I think the BDEDemoServer can still serve its purpose, because you can use it as a starting point when writing your own Server using a Database Engine of your choice (I'm guessing it won't be the BDE). If you get stuck, please let me know.
