Inheritance : what happens with relations??

Hi,

I've created a base form (form1) which contains three listboxes and a dataset with three tables (tblMainGroup, tblGroup, tblSubGroup). In the base form I've also created relations between the tables. Every listbox is filled with a table from the dataset based on what the user selects in the listboxes.

In another form (frmIngaveBedrijf) I also needed the three listboxes, so I inherited the baseform in this form.

When I compile the application (frmIngaveBedrijf is set as the startup form) I get the error message: "cannot create childlist for field tblMainGroup". I don't understand this because everthing works in the baseform.

Am I doing something wrong (eg should the base form be loaded first instead of frmIngaveBedrijf) or is there something wrong with the relations.

I added the code.


I would appreciate your help.

Thanks

Tom

Nobody??

FrmIngaveBedrijf is an inherited form of form1, so I suppose I can use the dataset that is created in form1. Is this correct or should I pass the dataset in the constructor of FrmIngaveBedrijf?

I'm really stuck here. I need this working.

Thanks,

Tom
