title: json and vb.net 10
body: <p>I am making a program that should collect the same information from different json.</p>
  
  <p>For example from:</p>
  
  <pre><code>http://steamcommunity.com/market/priceoverview/?appid=730&amp;currency=3&amp;market_hash_name=AK-47%20%7C%20Black%20Laminate%20%28Factory%20New%29
  </code></pre>
  
  <p>I get JSON of:</p>
  
  <pre><code>{"success":true,"lowest_price":"84,66\u20ac"}
  </code></pre>
  
  <p>I want to take lowest price!
  So far i have managed to get this info into where i want! With one ore two of that its ok but i i try to get 1000 different "lowest_price" from different urls there's a problem! Can you help me find a better way to gather all those prices?
  I want to take the number and place them in different labels.</p>
  
  <p>For example</p>
  
  <pre><code>Try
      Dim request As Net.HttpWebRequest
      Dim response As Net.HttpWebResponse = Nothing
      Dim reader As StreamReader
      request = DirectCast(WebRequest.Create("http://steamcommunity.com/market/priceoverview/?appid=730&amp;currency=3&amp;market_hash_name=AK-47%20%7C%20Black%20Laminate%20%28Factory%20New%29"), HttpWebRequest)
      response = DirectCast(request.GetResponse(), HttpWebResponse)
      reader = New StreamReader(response.GetResponseStream())
      Dim FN1 As String
      FN1 = reader.ReadToEnd()
      Dim jResults As JObject = JObject.Parse(FN1)
      Dim results As List(Of JToken) = jResults.Children().ToList()
  
  
      Dim json As JObject = JObject.Parse(FN1)
      Dim fn1ts As String = (json.Item("lowest_price"))
      label1.text = fn1ts
  Catch ex As Exception
      label1.text = "N/A"
  End Try
  </code></pre>
  
  <p>I take the number from the json, but I want to do this for about 1200 different prices and labels. Is there any way to massively do that?</p>
  
  <p>The problem is that i repeated the code for 200 urls and when i tested my program it just did load the labels! i stuck! (probably doing the procces) and for about half an hour nothing! I tried with backgroundworked but then i remembers that it can not change label texts! </p>
  
  <p>I want a want that i will get those json data url by url and save them to an xml file probably, and when is all done then load all of them to the labels!</p>
