Invalid pointer operation
Posted: Tue 28 May 2019 19:00
Hello,
for a new Project I am testing different ORM Components for Delphi.
I have downloaded the current Trail version of Entitydac and Unidac. I made a sample of Code mapped classes with the Entity Developer. On my Form I have a TEntityConnection which is connected via Unidac to SQL Express 2014 Server. I have a TEntityXMLModel where the XML file the Entity Developer created is loaded in. If I now call EntityConnection1.CreateDatabase(nil, [moCommitEachStatement]) to create the database model I got an error message "invalid pointer Operation" and no changes to the database has been applied. What is the reason for this ?
Greetings
