Excel VBA to JS: How does one pass rectangle coordinates to a JS function.

Question

I have an Excel VBA sub that calls a folder level JS function and I'm trying to pass a set of rectangle coordinates.
This is the VBA code:
Sub BarcodeDoc_PDF417(pdfFileName As String)
    Dim AVDoc As Acrobat.CAcroAVDoc
    Dim PDDoc As Acrobat.CAcroPDDoc
    Dim myApp As Acrobat.CAcroApp
    Dim jso As Object
    Dim bcTmpFile As String
        bcTmpFile = "C:\Temp\bcTmpFile.pdf"
        Set myApp = CreateObject("AcroExch.App")
        Set AVDoc = CreateObject("AcroExch.AVDoc")
            If AVDoc.Open(pdfFileName, "") Then
                Set PDDoc = AVDoc.GetPDDoc
                Set jso = PDDoc.GetJSObject
                    jso.myAdd417Barcode 'This is where the coordinates get passed.
                    PDFSave PDDoc, bcTmpFile
                myApp.CloseAllDocs
                myApp.Exit
                Set AVDoc = Nothing
                Set jso = Nothing
                Set PDDoc = Nothing
                Set myApp = Nothing
            Else
                MsgBox "Sub: BarcodeDoc_PDF417. Document not found:" & vbCrLf & vbCrLf & pdfFileName
            End If
End Sub
This is the folder level JS script:
function myAdd417Barcode(myCoords)
//The line below is just for testing. Will come out once I can pass the coords in from my VBA sub.
//var myCoords = [324, 756, 540, 720];
InsertPDF417Barcode(this, myCoords);
I've tried to pass the coords as a string and an array, both to no avail. Any ideas?
Thanks.

Answer 1

I tried typing the array as a variant (in the VBA code), but the JS script didn't like that either.
I then changed the JS script to this:
function myAdd417Barcode(n1, n2, n3, n4)
  var bcCoords = [n1, n2, n3, n4];
  InsertPDF417Barcode(this, bcCoords);
and passed it 4 integers thinking it would accept them in a way that I could then define the rectangle coordinates as shown above. It didn't work, and the error I get is that myCoords (in the script below) "isn't defined".
var InsertPDF417Barcode = app.trustedFunction( function(doc, mycoords)
  app.beginPriv();
  var bcIconFileName = "/C/Temp/bcTmpImage.pdf";
  //var bcCoords = [324, 756, 540, 720];
  var t = doc.addField("bcFormID", "button", 0, myCoords);
  t.display = display.visible;
  t.buttonPosition = position.iconOnly;
  t.buttonScaleHow = scaleHow.proportional;
  t.buttonScaleWhen = scaleWhen.always;
  t.buttonFitBounds = true;
  t.setButtonIcon
  var x = doc.importIcon("myIcon", bcIconFileName, 0);
  var f = doc.getField("bcFormID");
  var i = doc.getIcon("myIcon")
  var y = f.buttonSetIcon(i);
  app.endPriv();
Any suggestions will be appreciated.
Thanks!
