Your First Aspose.Diagram Application - Hello World

This tutorial shows how to create a very first application (Hello World) using Aspose.Diagram' simple API. This simple application creates a Microsoft Visio file with the text ‘Hello World’ in a specified Page.

Creating the Hello World Application

The steps below creates the Hello World application using the Aspose.Diagram API:

1. Create an instance of the Diagram 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 Visio file, or open an existing Visio file.
4. Create a new text box.
5. Insert the words Hello World! into a text box.
6. Generate the modified Microsoft Visio file.

The implementation of the above steps is demonstrated in the examples below.

Code Sample: Creating a New Diagram and Writing Hello World!
