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

Dim pdf As Chilkat.Pdf
Set pdf = Chilkat.NewPdf

' Load a PDF containing 2 remaining unsigned signature fields:

success = pdf.LoadFile("qa_data/pdf/doctor_patient_parent.pdf")
If (success = False) Then
    Debug.Print pdf.LastErrorText
    Exit Sub
End If

' Note: This example requires Chilkat v9.5.0.90 or greater.
Dim json As Chilkat.JsonObject
Set json = Chilkat.NewJsonObject
Dim success As Boolean
success = pdf.GetUnsignedSigFields(json)

json.EmitCompact = False
Debug.Print json.Emit()

' 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]")
    Debug.Print strVal
    i = i + 1
Loop
