I use this script to get geocodes for any address in germany:
Public Function getGoogleMapsGeocode(sAddr As String) As String
Dim xhrRequest As XMLHTTP60
Dim sQuery As String
Dim domResponse As DOMDocument60
Dim ixnStatus As IXMLDOMNode
Dim ixnLat As IXMLDOMNode
Dim ixnLng As IXMLDOMNode
' Use the empty string to indicate failure
getGoogleMapsGeocode = ""
Set xhrRequest = New XMLHTTP60
sQuery = "http://maps.googleapis.com/maps/api/geocode/xml?sensor=false&address="
sQuery = sQuery & Replace(sAddr, " ", "+")
xhrRequest.Open "GET", sQuery, True
xhrRequest.send
Set domResponse = New DOMDocument60
domResponse.LoadXML xhrRequest.responseText
Set ixnStatus = domResponse.SelectSingleNode("//status")
If (ixnStatus.Text <> "OK") Then
'Exit Function
End If
Set ixnLat = domResponse.SelectSingleNode("/GeocodeResponse/result/geometry/location/lat")
Set ixnLng = domResponse.SelectSingleNode("/GeocodeResponse/result/geometry/location/lng")
getGoogleMapsGeocode = ixnLat.Text & ", " & ixnLng.Text
End Function
When I type the query string into the browser it returns a valid xml response with the geocodes. If I let vba do it, I get an error. Is there something I should know?
responseText :
"<?xml version="1.0" encoding="UTF-8"?>
<GeocodeResponse>
<status>INVALID_REQUEST</status>
</GeocodeResponse>
" : String : Modul8.getGoogleMapsGeocode

this is the code i have, dim sline from string to json, i have try it and search on google, but i havent done yet...
please help
Dim sURL As String
sURL = TextBox1.Text
Dim wrGETURL As WebRequest
wrGETURL = WebRequest.Create(sURL)
Dim myProxy As New WebProxy("myproxy", 80)
myProxy.BypassProxyOnLocal = True
wrGETURL.Proxy = myProxy
wrGETURL.Proxy = WebProxy.GetDefaultProxy()
Dim objStream As Stream
objStream = wrGETURL.GetResponse.GetResponseStream()
Dim objReader As New StreamReader(objStream)
Dim sLine As String = ""
Dim i As Integer = 0
Do While Not sLine Is Nothing
i += 1
sLine = objReader.ReadLine
If Not sLine Is Nothing Then
Console.WriteLine("{0}:{1}", i, sLine)
End If
Loop
Dim respon As Array = sLine.ToArray()
Console.ReadLine()
Console.WriteLine(respon("traceNo"))
Console.ReadLine()
i want to convert the Dim sline to json, how it possible?
Newtonsoft.JSON is a VERY handy NuGet to easy use JSON in VB.Net.
Seperate your lines into a List(Of Integer, String) (i,sLine)
and Serialize it with
Dim yourJSONString = JsonConvert.SerializeObject(yourList)
I shall get to the point and it is probably an easy answer for someone. The JSON being returned from HubSpot may or may not include a property such as phone and address because it is not filled out in HubSpot. This causes an error in the For Each block below:
System.NullReferenceException
HResult=0x80004003
Message=Object reference not set to an instance of an object.
Source=HubSpotGetAllCompanies
How can I handle it so that if there is no property for telephone for example, I can put in a DBNull value instead.
Thanks in advance!

Try using the Null Propagation Operator ? between any token accessors that may not be filled:
Dim telephone = If(item("properties")("phone")?("value").ToString(), DBNull.Value)
If a particular token is Nothing, it will return Nothing to the If and set the variable to DBNull.Value
Im looking to get a list of all the devices on my work admin teamviewer account using vb.net. I would also like to be able to change the "Alias" of a given device using it's device id. i know very little about API's. i found the following example but i am not sure how to adapt it to get the json response.
instead of the accesstoken, i believe i need to use the client id and secret id along with the authorization code in order to use this. if i run it in it's current start i get a 401 unauthorized error. Any help would be appreciated.
i also have no idea how to use "PUT" to change the Alias using the device id which will both be entered in textboxes. ex alias = textbox1.text and device_id = textbox2.text
Private Sub SurroundingSub()
Dim accessToken As String = "xxxxxxxxxxxxxxxxxxx"
Dim apiVersion As String = "v1"
Dim tvApiBaseUrl As String = "https://webapi.teamviewer.com"
Dim address As String = tvApiBaseUrl & "/api/" & apiVersion & "/devices"
Try
Dim request As HttpWebRequest = TryCast(WebRequest.Create(address), HttpWebRequest)
request.Headers.Add("Bearer", accessToken)
request.Method = "GET"
Dim webResp As WebResponse = request.GetResponse()
Catch __unusedException1__ As Exception
msgbox(__unusedException1__.ToString)
End Try
End Sub
Here is the Get all devices code:
Private Sub get_teamviewer_devices()
Dim accessToken As String = "XXXXXXXXXXXXXXXXXXXXX"
Dim apiVersion As String = "v1"
Dim tvApiBaseUrl As String = "https://webapi.teamviewer.com"
Dim address As String = tvApiBaseUrl & "/api/" & apiVersion & "/devices"
Dim result_json As String = Nothing
Try
Dim request As HttpWebRequest = TryCast(WebRequest.Create(address), HttpWebRequest)
request.Headers.Add("Authorization", "Bearer " & accessToken)
request.Method = "GET"
Dim webResp As WebResponse = request.GetResponse()
Using reader = New StreamReader(webResp.GetResponseStream)
result_json = reader.ReadToEnd()
End Using
TextBox1.Text = result_json
Catch __unusedException1__ As Exception
MsgBox(__unusedException1__.ToString)
End Try
End Sub
Here is the PUT portion to change an alias:
Public Sub change_alias(ByVal device_id As String, ByVal alias_str As String)
Dim accessToken As String = "XXXXXXXXXXXXXXXXXXXXX"
Dim apiVersion As String = "v1"
Dim tvApiBaseUrl As String = "https://webapi.teamviewer.com"

Here is what I've come up with so far:

I can't figure out the payload portion. This script is a modified version of what I'm using for other API's. Here is the Bitfinex API info

Is everything right except pay load? How do I complete "payload = parameters-dictionary -> JSON encode -> base64" portion of the API details?
Try this.
