Indicates the kind of configuration file to create.

Windows 3.1 And Windows 95/NT

When checked, new and edited configuration files are saved in a combination 16-bit/32-bit format that can be used by both Windows 3.1 and Windows 95 or Windows NT applications.

Any System and Driver settings existing in the current configuration file are written to the new configuration file.

All remaining System and Driver settings are written to the Registry. Entries are saved from their point of origin.

Database settings are saved to the new configuration file.

NET DIR is saved to the new configuration file.

Windows 95/NT Only

When checked, the new or modified configuration file is only usable by 32-bit applications.

System and Driver settings are saved to the Registry. The Registry is always updated if the configuration file is the default.

NOTE: If the IDAPI.CFG file is not the default, the file MUST be saved as a composite 16-/32-bit file.

Database settings are saved to the new configuration file.

NET DIR is saved to the new configuration file.

Select Configuration Modes To View

Indicates which ODBC drivers and data sources to display: those created just for this session, only those administered by BDE, and/or all installed on the system. Since these are check boxes, you can choose any or all. In the case of objects with the same name, Session overrides Persistent and Persistent overrides Virtual. Note: These settings are stored in the Registry in the ViewMode key under Borland, Database Engine.

Session

When checked, the tree in the left pane shows ODBC drivers and data sources that are created "on the fly" through program code for just this session.

Persistent

When checked, the tree in the left pane shows ODBC drivers and data sources that are used with BDE applications and configured with the BDE Administrator. If Persistent is unchecked, users won't see a tree view for Native and ODBC drivers and their aliases in the BDE Administrator. Only System INIT information will appear.

Virtual

When checked, the tree in the left pane shows all ODBC drivers and data sources installed on the system, whether or not they are used with BDE applications and configured with the BDE Administrator. Virtual data sources cannot be deleted or renamed. Virtual data sources are administered with the ODBC Administrator supplied by the vendor and appear in BDE with default parameters. If you configure a virtual data source in BDE, it becomes persistent and is then stored in the BDE configuration file. Note: When an ODBC driver or data source changes from virtual to persistent with Persistent checked and Virtual unchecked, the driver won't appear in the tree until you choose View|Refresh.
