Now we would like to call the procedures on that form from several other forms. We don't want to create a connection on each form (app is mdi). How could we do this, and mostly, how would we reference that 'common' form. Kids Regards ...Show All

  I'm starting the following project: A multi database (SQL Server, Oracle and Firebird) using Winforms in the presentation layer and Web Services in the middle tier.

  I am using Visio for Enterprise Architects that came with the latest release of Visual Studio 2005 and am designing a new database from scratch. I have commented all tables and columns but cannot find a way to pass those values into the database during creation.

The message system is Biztalk but that should be irrelevant. I would like guidance on how to design and implement the adapters that take binary data from the business layers and communicate with the backbone. To produce a good adapter, I think I should implement several messaging design patterns. ...Show All
