通过VBA填充PDF组合框

我有下面的代码来填充PDF文档中的组合框。据我所知,代码是正确的 Acrobat Forms API Reference

但是,代码在服务器上失败 PopulateListOrComboBox

对象“IField”的方法“PopulateListOrComboBox”失败

Dim acroApp As Acrobat.acroApp
Set acroApp = New Acrobat.acroApp

Dim myForm As Acrobat.AcroAVDoc
Set myForm = New Acrobat.AcroAVDoc

Dim bOK As Boolean
bOK = myForm.Open("C:\Users\sholtzman\downloads\wordFormTest.pdf", "temp")

Dim theRealForm As AFORMAUTLib.AFormApp
Set theRealForm = New AFORMAUTLib.AFormApp

Dim pdField As AFORMAUTLib.Field
Set pdField = theRealForm.Fields.Add("triaCoverage", "combobox", 0, 10, 20, 100, 200)

Dim items(2) As String
items(0) = " "
items(1) = "Accept"
items(2) = "Reject"

pdField.PopulateListOrComboBox items

自动化错误未指定的错误

Dim myPDForm As Acrobat.AcroPDDoc
Set myPDForm = myForm.GetPDDoc

Dim jso As Object
Set jso = myPDForm.GetJSObject

jso.getField("triaCoverage").setItems(1) = " "
