Deleting a Data Source

1. Choose Start | All Program Files | Loftware Labeling | Data Sources (ODBC).

2. Select the data source from the Data Sources list in the Data Sources dialog box.

3. Click Remove, and thenclick Yes to confirm the deletion.

Data Source Conversion

The 32-bit data sources used with the ODBC Desktop Database Drivers version 2.0 are automatically

converted to new 32-bit data sources for version 3.5 drivers. No conversion is provided for 16-bit data

sources. To change a 16-bit data source to a 32-bit data source, create a new 32-bit data source, and then

(optionally) delete the old 16-bit data source. A 32-bit data source and a 16-bit data source cannot share

the same name.

Hints and Troubleshooting ODBC

l If you are moving your label from one computer to another, and it is connected to an ODBC

datasource, make sure that the computer you are moving to has the exact same datasource name

in the ODBC Control Panel. If you are unsure of what datasource name was used, you may

double click a field on your label that is connected to a database in design mode. The datasource

name, table, and field are reported.

l Datasource names are not case sensitive.

l Be aware of illegal and reserved datasource names. Stay away from names like Table, Field,

Database, and Text. Do not include special characters like \ , . - +.

l If you get a Type Mismatch error when retrieving data, it means that the field column type in the

database has changed since the connection was made. Reconnect the associated field on your

label.

l Do not create a subdirectory with the same name as your database under the directory in which

your database resides. This creates a "Couldn’t open file unknown" message.

l If using Microsoft Access, make sure that you have checked Read/Design permissions. If they are

not checked, you may get a situation where you can see table names but no field names.

l Avoid using ODBC indexes whenever possible.

l When first choosing a datasource, you may get an error message. Continue by clicking either OK

or Cancel, and try to reconnect to your database. Loftware Label Manager always accesses the

first DSN by default. If the DSN is not valid, a warning alerts you to choose another DSN. The

chosen DSN becomes the default DSN after connecting to your database.

l Records added to the database from an external location while printing from another may not be

immediately available to the Loftware print modules.
