I am developing an ActiveX control for IE which is invoked through javascript. The ActiveX control is developed in visual basic and it has an array of strings. How will I use this array of strings in javascript.
Eg :-
var a = new Array()
a = objActiveX.GetArray(); // call to active x returns array of string, how will I loop through this in javascript.
The above line does not work. I want to loop through each string in javascript.
Advise.
Usually, arrays returned from COM/OLE/ActiveX components are SAFEARRAYs. There's a special object in JScript called VBArray that adapts between the two.
See http://blogs.msdn.com/b/david.wang/archive/2006/07/04/howto-convert-between-jscript-array-and-vb-safe-array.aspx for a good example of going back and forth between JavaScript arrays and SAFEARRAYs.
More detailed info on VBArray here:

Note that this is part of JScript -- I'm not 100% sure that IEs default scripting runtime is JScript, but I think so.
This function will convert a multi-dimensional VB safe-array into a multi-dimensional javascript array.
Try it out, Let me know if you can break it.
