If you want to use objects like XSIApplication, XSIMath, XSIUtils, and XSIFactory in NetView scripts, you need to know the [mostly undocumented] progIDs of those objects.

window.onload = onLoadHandler;

//-------------------------------------------
// OnLoadHandler for any HTML page 
// that includes this .js file
//-------------------------------------------
function onLoadHandler() {

	//-------------------------------------------
	// Create instances of Softimage objects.
	//-------------------------------------------

	try {
		var Application = new ActiveXObject('XSI.Application');
		var XSIUtils = new ActiveXObject('XSI.Utils');
		var XSIMath = new ActiveXObject('XSI.Math');
		var XSIFactory = new ActiveXObject('XSI.Factory');
	} catch ( e ) {
		alert( e );
	}
}

Here’s a script that uses WMI to find the progIDs of XSI COM automation objects:

var sComputer = XSIUtils.Environment("COMPUTERNAME");

ListCOM( sComputer );

function ListCOM( computer )
{ 
	var wmistr = "winmgmts:{impersonationLevel=impersonate}!\\\\"; 
	wmistr += computer + "\\root\\cimv2";
	var wmi = GetObject( wmistr );
	var query = "SELECT * FROM Win32_ClassicCOMClassSetting";
	var com = wmi.ExecQuery( query );
	var ecom = new Enumerator( com );
	for( ; !ecom.atEnd(); ecom.moveNext() )
	{
		var icom = ecom.item();  
		if ( icom.Caption != null && icom.Caption.indexOf( "XSI" ) > -1 && icom.VersionIndependentProgId != null)
		{
			LogMessage( "name   : " + icom.Caption );
			LogMessage( "progid : " + icom.VersionIndependentProgId );
			LogMessage( "" );   
		}
	} 
}
