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 Working with Database Connections in Connecting to Your Database.
To create a new DataWindow object:
