Building a DataWindow object
You use a wizard to build a new DataWindow object. To create a DataWindow object or
use the DataWindow painter, you must be connected to the database whose
data you will be accessing. When you open the DataWindow painter or select
a data source in the wizard, PowerBuilder connects you to the DBMS and
database you used last. If you need to connect to a different database,
do so before working with a DataWindow object.
Column limit There is a limit of 1000 on the number of columns in a DataWindow object.
For information about changing your database
connection, see Connecting to Your Database.
To create a new DataWindow object:
-
Select File>New from the menu
