You use ActiveX controls to embed an application in a Web page. Microsoft Internet Explorer 3.x or later supports ActiveX controls with which you can add custom capabilities such as audio and movie players, calendars, custom buttons, and forms to your pages. You can view documents such as Microsoft Office files in Internet Explorer without launching the associated program. Site visitors must use Internet Explorer 3.x or later to view content created with ActiveX controls. To view the content in Netscape Navigator 4.x, site visitors must install special plugins. For information, go to www.microsoft.com.
To insert an ActiveX control:
In Page view, select the ActiveX Control tool
from the Plug-Ins toolbar.
Draw a box to indicate the position of the ActiveX control.
The Insert ActiveX Control dialog appears, listing the ActiveX controls currently installed on your system. The bottom section shows the selected ActiveX control, which has an .ocx or .dll extension.

Select Set codebase to add the codebase parameter to the generated HTML and ensure that the ActiveX control is published to the Web site. If a visitor who does not have the ActiveX control you are using views the Web site, the option to download the control is offered.
Select the control you want and click OK. The ActiveX control appears on your page, and the ActiveX Control Properties palette appears.

The General tab displays the options for the selected control.
Note:
If you use an ActiveX control that references an external file, such as a .pdf file, you must specify the relative path of the file as it will be in the final published site. First you must add the file as an asset of the site and set it to always publish. See Adding a File Asset. To determine the file’s relative path in the final site, look at the publish directory structure listed in Publish view.
To provide text that the browser displays if it cannot launch the ActiveX control, enter the text in the AltTag field.
To change an option, select it and enter the information in the field.
To accept any text you enter, click the check mark or move the cursor to another field.
To cancel the change, click the X.
To use the native property page for the ActiveX control, click the Properties button. You can change the control’s settings using the native property page instead of NetObjects Fusion properties. Some ActiveX controls do not have a native property page.
To insert HTML tags and scripts, click the HTML button. See Working with HTML Directly.
You can add actions to ActiveX controls using the Actions tab.
