Your First Aspose.Diagram Application - Hello World

This beginner’s topic shows how developers can create a simple first application (Hello World) using Aspose.Diagram' simple API. The application creates a Microsoft Visio file with the words Hello World in the page.

Creating the Hello World Application

To create the Hello World application using Aspose.Diagram API:

1. Create an instance of the Workbook class.
2. Apply the license:
   1. If you have purchased a license, then use the license in your application to get access to Aspose.Diagram' full functionality
   2. If you are using the evaluation version of the component (if you’re using Aspose.Diagram without a license), skip this step.
3. Create a new Microsoft Visio file, or open an existing file in which you want to add/update some text.
4. Insert the words Hello World! into the page accessed.
5. Generate the modified Microsoft Visio file.

The examples below demonstrate the above steps.
