' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Pdf")
set pdf = Server.CreateObject("Chilkat.Pdf")

' Load a PDF containing 2 remaining unsigned signature fields:
success = pdf.LoadFile("qa_data/pdf/doctor_patient_parent.pdf")
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( pdf.LastErrorText) & "</pre>"
    Response.End
End If

' Note: This example requires Chilkat v9.5.0.90 or greater.
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonObject")
set json = Server.CreateObject("Chilkat.JsonObject")
success = pdf.GetUnsignedSigFields(json)

json.EmitCompact = 0
Response.Write "<pre>" & Server.HTMLEncode( json.Emit()) & "</pre>"

' Result:
' {
'   "unsignedSigField": [
'     "doctor_signature",
'     "parent_signature"
'   ]
' }

' To iterate over the field names:

i = 0
count_i = json.SizeOfArray("unsignedSigField")
Do While i < count_i
    json.I = i
    strVal = json.StringOf("unsignedSigField[i]")
    Response.Write "<pre>" & Server.HTMLEncode( strVal) & "</pre>"
    i = i + 1
Loop
