QUESTION:
As of Visual DataFlex 11.0, a workspace can have a "default" database, and some of Database Builder's menus and dialogs change depending on the "default" database, to make it easier and more intuitive to work with. How does VDF determine what the default database for a workspace is?
ANSWER:
If you created the workspace using VDF 11.0 or higher, the DDSrc folder of the workspace will contain a file named connection.ini. This file contains numerous tags in square brackets [for example]. The top most tag is [Connection] and it contains a DriverName= line.
For example, a connection.ini file in a workspace that has MS SQL as its default database starts with this information:
[Connection]
DriverName=MSSQLDRV
To use ODBC as default driver, use:
[Connection]
DriverName=ODBC_DRV
To use the embedded database as default driver, use:
[Connection]
DriverName=DATAFLEX
If the file does not exist, because the workspace is from an older VDF revision than 11.0, you can copy this file from one of the sample workspaces or simply create a new one.
