Hi there all, ok ive created a activex control and it contains a dbgrid among other things, and using the visual interface wizard i have carried a property over from a data source and this property that i have created has the type datasource, but whenever i try and run the program it gives me the error, undefined user type datasource. Has anyone got an idea how i create a datasource type myself so that i will be as required? thanks,

Piers
