I haven't personally developed one but it will be different for each browser you wish to support.  There isn't a way to just make a "universal" plugin.  Even the OS will matter when developing a plugin.

For Firefox you would want to start at https://developer.mozilla.org/en/Gecko_Plugin_API_Reference/Plug-in_Development_Overview .  If I remember right the development is usually done in C language.

MS is not as nice about releasing info on plugin development, at least publically searchable.  The MSDN area would be where I would start and I believe has some info.  I was not able to find a good link to provide as a starting place.

Let me know how this helps or if you have a question.

You surely must be referring to the info you have posted or your participation.  If that is a comment on my post AND you want anything more from me you really must respond better.  As the other expert mentioned your question lacks any details and specifics so you can't really expect much when you provide nothing.  For what you provided my response was accurate and gives you a start.

Michel PlungjanIT ExpertCommented:
Yes it is possible
It needs a plugin for Firefox and an ActiveX for IE

Possibly Silverlight for IE8

tittu,

That is actually a different question from what you asked initially.  Just so Mplungjan's comment isn't misunderstood you can't access methods in a DLL you make just with Javascript.  You asked about a plugin and Mplungjan mentioned ActiveX.  A Java applet would also be an alternative.  The advantage of an applet is it will be easier to support various browsers with it.  However all of these can still be limited by browser security settings and "trust" settings so it will also depend on the dll and what it would do.

The question is still to general to say much more than a general answer.  I do hope this help you know what is involved.  If you have a question let us know.  If you need more info then provide us with more specifics and responses to what we have said/asked.

Please explain why you close this as you did and the "partially accepted" grading comment.  Like Mplungjan I am confused by how this was closed, including the B grade.  The answers were very complete considering the details provided (or lack thereof).  If the question you accepted was the answer then a split seems appropriate.  That comment obviously adds to the other expert's comment.
