       there are  many internet browsers,such as microsoft IE, netscape,mozilla etc.IE is the most popular tool under windows platform.It supports activex controls,that's a great thing and there're many activex controls in use all over the world. they make the world more interesting and attractive. but we can not directly use these controls under mozilla,netscape browsers.instead of activex control,they use plugins,which have same functions as activex controls. we can develop plugins using vc++.
      how to develop?
      First,you should download the sdk package plugins (http://www.mozilla.org/projects/plugins/)
 open that page and click here for win32 link (beacause we are under win32 platform).after downloading,unpack it.there's a win32sdk folder.it has four subfolder: gecho-sdk moztools sdk and
xpipackager.
       gecho-sdk:  sdk APIs
       moztools : tools for mozilla develop
       sdk :  examples for plugin
       xpipackager:   tools for xpi.
