问题
I have an ActiveX control which is designed to * Search for nearby wireless networks * Create a wireless access point * Manage network adapters
I would like this plugin to work in Google Chrome/Firefox. In IE; I can use the following code to embed:
<object classid="clsid:33FC4347-8118-4DB5-BFBE-8FCF2C96A997" width="32" height="32" id="thectrl"></object>
and I create a wireless network as follows (in JavaScript): thectrl.createNetwork("test",0,null,"NONE",3); The ActiveX has an IDL file, and outputs to OCX format. How do I turn this into a plugin for Google Chrome/Firefox?
回答1:
If you want to rewrite it to support NPAPI, an easy way is to use the FireBreath framework. It gives you an abstraction over the plugin architectures, is cross-platform and allows you to support NPAPI and ActiveX from one source base.
But then again i am biased, so if you want to do it manually instead, here are some starting points:
- a three-part NPAPI tutorial
- MDC plugin section
- The "Hello World" of NPAPI plugins

It would be best if you have the source code of the ActiveX and let the NPAPI headers expose the functionality you need. If you want to turn that into a plugin, you would definitely need C++ knowledge to create that NPAPI library.
So your only solution at this point is creating your NPAPI plugin. You might try some of the Mozilla examples at https://developer.mozilla.org/En/Plugins. If you are completely new to NPAPI though, maybe you'd want to start with https://developer.mozilla.org/en/Gecko_Plugin_API_Reference.
To start developing, all you need are the standard NPAPI headers, which you can now get from http://code.google.com/p/npapi-headers/source/browse/
An example plugin we use in Chromium: http://src.chromium.org/viewvc/chrome/trunk/src/webkit/glue/plugins/test/
