To insert any of these objects in a page, place the cursor where you want the object to be and then click the appropriate button on the Objects palette. The Object palette buttons insert the necessary HTML to make the object appear on the page. Use the Property inspector to specify the source data file, dimensions and other parameters.
Note: There is not a widely accepted standard for identifying data files for ActiveX controls. See the documentation for the ActiveX control you're using to find out which parameter to use.
