I also noticed that (using Datacontrol.newrecord), no new records are added to the database. I went through this tutorial 3 times, rewatching all the videos and checking my project over and over, but the same error message comes back (showing in the OP) and no records are being created.
Is the use of a Datacontrol to bind UI and database maybe not the best way to control data? (I read that in a comment somewhere).
It is NOT… and in the opinion of many (most) people here it should be avoided. Straight SQL is you best bet, and it not only is usually faster, but also makes you app database agnositic, and safer
It would be nice to have the project file, yes. I searched for it but could not find it. Or I could post my project file so someone could debug it and then post it here?
