Once you have installed the dialog box component, you can use it as you would any of the common dialog boxes, by placing one on a form and executing it. A quick way to test the About box is to add a command button to a form and execute the dialog box when the user clicks the button.

1. Create a new project.
2. Place an About box component on the main form.
3. Place a command button on the form.
4. Double-click the command button to create an empty click-event handler.
5. In the click-event handler, type the following line of code:

AboutBoxDlg1.Execute;

AboutBoxDlg1->Execute();

6. Run the application.

You can further test the component by setting the various properties of the About box component and again running the application.
