Previously, the Web Design-time Control SDK provided you with the type libraries needed to generate text and insert it into a document. Using this SDK, you can create DTCs that:
For example, in Visual InterDev, adding a RecordSet DTC to the page determines what fields and records are available for display and manipulation by other DTCs on the page. The RecordSet DTC publishes choices to notify other DTCs which fields and records are available. Another DTC can subscribe to the choices using ChoiceSinks and ChoiceFilters to specify which choices it is interested in.
For more information about implementing choices, see Sharing Information Between DTCs.
For example, you might want your DTC to use the choices published by the RecordSet DTC, launch the Query Builder, or expose its object model to the editor.
For more information, see Communicating with Visual InterDev.
