A Real World Scenario

Assume you already have a shop software.

Now, this software should be able to create bills for your customer.

What will be the required steps ?

A Real World Scenario Todo's

Outside your application:

Create an OpenDocument text document as a template.

Use placeholder to mark insert positions.

Add the document as application resource.

A Real World Scenario Todo's

Inside your application:

Reference the AODL assembly.

Load your template file.

Find the corresponding placeholder.

Replace them with the data from your application.

Save the file.
