Change in Terminology for Data View and SQL Debugging

In the context of Data View and SQL Debugging in Visual C++ 4.2 Enterprise Edition, the term "Data Source" was used to describe the set of data that a database application accesses. In Visual C++ 5.0 Enterprise Edition, this term was changed to "Data Connection" to be consistent with terminology used across Visual Studio Products.

Database Projects

In Visual C++ 4.2 Enterprise Edition, you could add a Data Connection to any type of Visual C++ project by selecting Data Connection from the Insert menu.

In Visual C++ 5.0 Enterprise Edition, a new project type has been created to allow more effective management of Data Connections. The new project type is called a Database Project. Data Connections can only be added to Database Projects by selecting Add to Project, then Data Connection from the Project menu.

For more information about working with Database projects, see the following sections of the online documentation:

• Working with Database Projects in the Visual Database Tools node
• Microsoft Visual Database Tools Overview in the Visual Database Tools node.
• Data View in the Developer Studio Environment User's Guide

Default or Identity Values Are Not Displayed When You Enter New Records into a Table

To display these values, requery the table by choosing Run from either the Query toolbar or from the Tools menu.

Converting VC 4.2 Projects When the Data Connection is Offline

Opening a Visual C++ 4.2 project that contains a data connection in the Visual C++ 5 development environment will attempt to create a workspace that contains the converted project and a database project that contains the data connection. If the database that the data connection refers to is offline, error messages will be displayed and the database project will not be created.
