ActiveX Enumerations

[JoeH]

Hi,

I'm using a COM DLL (created in VB) in my javascript code and can
successfully call its methods and get/set its properties. There are
also some Public enumerations defined in the ActiveX DLL I'd like to
access -- is this possible?

Thanks,

Joe

Not being an expert, my best bet would be to use an Enumerator (JScript
specific).

The following short example may get you started:

var wmi = new
Enumerator(GetO bject("winmgmts :").InstancesOf ("Win32_process "));

for( ; !wmi.atEnd(); wmi.moveNext() )
{
var process = wmi.item();
alert( "process.na me" );
}


I've told that this Enumerator stuff helps iterating (using atEnd,
moveNext and Item) through COM enumerations.

Hope this helps,

Alexis

Re: ActiveX Enumerations

Thanks Alexis,

I was hoping I'd be able to reference the enumeration items (from the
DLL) by name vs. looping through them -- but this was an informative
code snippet nonetheless.
