Adobe Reader - Adding Toolbar : hello world example

Question

Hi everyone,
I would like to create a "Toolbar Button" for Adobe Reader which supports all version of it. 
After a long search for this over the web found some article suggesting that this can be done with either of 2 methods.
1. Acrobat Javascript.
2. Acrobat Plugins.
1. Acrobat Javascript:
     I am successful in creating a "ToolBar Button" in Adobe Reader with below script placed in "C:\Program Files\Adobe\Reader 10.0\Reader\Javascripts"
Script:
function helloWorld()
app.alert("Hello World");
app.addToolButton({
       cName: "helloWorldBtn",           // A name for your button
       cExec: "helloWorld()",               //Function to Call
       cLabel: "Hello World",               //The Text on the Button
       cTooltext: "Say Hello World",     //The Help Text
        cEnable: true
Problem with Javascript:
The only problem faced with Javascript implementing my scenario is "I coudn't call a ActiveX or DLL method from this Javascript".
I tried creating new ActiveXObject in the code but it thorws runtime error saying it ActiveXObject is a unrecognized key word.(The same "new ActiveXObject" works fine from normal Javascrirpt.
2. Acrobat Plugins.
I couldn't find a good "Helloworld" sample for building a sample toolbar over internet. I believe from Plugins it would be easier to call other DLL's method by adding a reference or over COM.
Could someone help me getting this done with a best simplest sample to do with. Please don't recommend me the SDK samples, I really don't understand anything out of it.
If we can create toolbar with C# or VB it would be so preferable for me.
Hope you got my problem. Thanks in advance.
Please revert me if any of my assumptions were wrong.

Answer 1

Yes, those are the two ways to create a toolbar button - either JavaScript or Plugin.
You are also correct that you can't do anything with ActiveX or DLL from Acrobat JavaScript - which is the same JavaScript engine as Mozilla/FireFox.  owever, many browsers add additional/custom objects (such as ActiveX), which may be what you are thinking of...
Plugins are written in C/C++ and they are documented in the Acrobat SDK.  You will need to download that to get building.  It includes documentation, sample code, etc.  HOWEVER, be aware that in order to develop a plugin for Reader you must obtain a license from Adobe.  There is a cost and process for this license and details are in the SDK.
