Demonstrates how to access values in a JSON array. Visual Basic 6.0

Dim success As Long
success = 0

Dim json As New ChilkatJsonObject

Dim jsonStr As String
jsonStr = "{ ""id"": 1, ""name"": ""A green door"", ""tags"": [""home"", 22, ""green""], ""price"": 125 }"

success = json.Load(jsonStr)
If (success <> 1) Then
    Debug.Print json.LastErrorText
    Exit Sub
End If

' Get the "tags" array, which contains "home", 22, "green"
Dim tagsArray As ChilkatJsonArray
Set tagsArray = json.ArrayOf("tags")
If (json.LastMethodSuccess = 0) Then
    Debug.Print "tags member not found."
    Exit Sub
End If

' Get the value at each array index. 
' Output will be:
' [0] = home
' [0] as integer = 0
' [1] = 22
' [1] as integer = 22
' [2] = green
' [2] as integer = 0

Dim arraySize As Long
arraySize = tagsArray.Size
Dim i As Long
For i = 0 To arraySize - 1

    Dim sValue As String
    sValue = tagsArray.StringAt(i)

    Debug.Print "[" & i & "] = " & sValue

    Dim iValue As Long
    iValue = tagsArray.IntAt(i)
    Debug.Print "[" & i & "] as integer = " & iValue

Next

' Note: The StringAt method returns the value as a string regardless of the type.

' The IntAt method returns the value as an integer.  If the value does not convert to 
' an integer, then 0 is returned
