I have a pdf form and Acrobat Pro installed on my machine. In MS Access I can write VBA code to open the form and fill out the fields. But I cannot figure out how to adjust the font size of a field (or other properties like color) using VBA.

Here is a snippet:

Dim oAVDoc As Object, oPDDoc As Object
Dim oJso As Object, oFld As Object

Set oAVDoc = CreateObject("AcroExch.AVDoc")

oAVDoc.Open("C:\Temp\test.pdf", "")

Set oPDDoc = oAVDoc.GetPDDoc

Set oJso = oPDDoc.GetJSObject

Set oFld = oJso.getField("TestFieldName")

oFld.Value = "This is the new value." '<-- works fine

oFld.FontSize = 14 '<-- "Object doesn't support this property or method"
oFld.Color = "red" '<-- also does not work

I figure there are probably javascript object properties for these, but I can't find any documentation on what they might be.

Thanks in advance.
