Do you have a rough estimate on when the release with the new mmDataAccessWebService class will be ready?

>>We are trying to use the property BindinSource in Windows Forms and Web Forms, but we are using Web Services in order to share the bussines logic in both clients. We have not found how to do this because we don't have the BO referenced in our forms. Can you tell me how to register the BO in the forms using Web Services?

>Web Services are stateless and if you have business objects hosted behind a Web Service there is no good way for the business object to raise events through a web service and have the user interface respond to the event.

>You need a business object on the workstation in order to make this happen. On the workstation you can use the business object's SetCurrentDataSet() method to store a DataSet retrieved from a web service in a business object. The business object will then raise an event to which user interface controls can respond. This can be a generic business object you use simply for data binding and you can have your "real" business objects hosted behind the web service.
>
>In our next release we are providing an mmDataAccessWebService class that can be used to call Web Services to retrieve and update data via Web Services. In this architecture you can host either a business object or just a data access class behind a web service and the data access class on the workstation will call the web service.
