Hi Craig, I don't know how, but it does succeed in finding the one with the name "SamDataModule", because it's not exactly access violations, but rather incorrect data. I'm thinking that maybe it has a list of Forms / Datamodules by name, and finds them by name?
But yeah, I was going to go on setting them at run time unless someone had a better answer.

If you create these objects at runtime, you must link the DataSource(s), (and the odd visual component as you mentioned) to the associated dataset at runtime. How else will the form know the address and which datamodule / dataset it's talking to? Regards, Craig.
