After inserting an ActiveX object, use the Property inspector to set other parameters. There is not a widely accepted standard for identifying data files for ActiveX controls. Consult the documentation for the ActiveX control you're using to find out which parameter to use. Click Parameters in the Property inspector to enter values for properties that don't appear on the Property inspector.

Double-click an ActiveX object to view the following properties in the Property inspector.

See also Shockwave, ActiveX, Java, and Netscape plugins overview.

The Property inspector initially displays the most commonly used properties. Click the expander arrow in the lower right corner to see all properties.

ActiveX is a name you enter to identify the ActiveX object for scripting. You can enter any name you like.

W and H specify the width and height of the object in pixels. You can also specify the following units: pc (picas), pt (points), in (inches), mm (millimeters), cm (centimeters), or % (percentage of the parent's value). The abbreviations must follow the value without a space, for example, 3mm.

Class ID identifies the ActiveX control to the browser. Enter a value yourself or choose one from the pop-up menu. When the page is loaded, the browser uses the Class ID to locate the ActiveX control required for the ActiveX object associated with the page. If the browser doesn't locate the specified ActiveX control, it attempts to download it from the location specified in Base.

Base specifies the URL containing the ActiveX control. Internet Explorer download the ActiveX control from this location if it has not been installed in the user's system.

Embed makes Dreamweaver add an EMBED tag within the OBJECT tag for the ActiveX control. If the ActiveX control has a Netscape plugin equivalent, the EMBED tag activates the plugin. Dreamweaver assigns the values you've entered as ActiveX properties to their Netscape plugin equivalents.

Src defines the data file to be used for a Netscape plugin if the Embed option is turned on. If you don't enter a value, Dreamweaver attempts to determine the value from the ActiveX properties entered already.

Align determines how the object is aligned on the page. See Alignment options for a description of each option.

Alt Img specifies an image to display if the browser doesn't support the OBJECT tag.

V Space and H Space specify the amount of white space in pixels above, below, and on either side of the object.

Data can specify a data file for the ActiveX control to load. Many ActiveX controls, such as Shockwave and RealPlayer, do not use this parameter.

ID defines the optional ActiveX ID parameter. This parameter is most often used to pass information between ActiveX controls.

Borders specifies the width of the border around the object.

Parameters opens a dialog box with which you can enter additional parameters to pass to the ActiveX object. Many ActiveX controls respond to special parameters.
