HttpUtils again

[madru]

Hi,

is there a way to use HttpUtil synchronous ? In my app I parse a downloaded XML file:

Sub Parser_EndElement (Uri As String, Name As String, Text As StringBuilder)
   If parser.Parents.IndexOf("channel") > -1 Then
      If Name = "name" Then
         Title = Text.ToString
         titles.add(Title)
         Log(Title)
      Else If Name = "address" Then
         Link = Text.ToString
         links.Add(Link)
         Log(Link)
      Else If Name = "type" Then
         ctype = Text.ToString
         ctypes.Add(ctype)
         Log(ctype)
      Else If Name = "iconUrl" Then
         icon = Text.ToString ' not used
         If icon="" Then
            icon = "http://192.168.252.255/dummy.png"
         End If
         Log(icon)
         icons.Add(icon)
         icon=""
      End If
   End If
end sub

Sub ImageUrlDone (Url As String)
If HttpUtils.IsSuccess(Url) Then
   bitmaps.Add(HttpUtils.GetBitmap(Url))
   Log("ImageUrlDone" & Url)
   HttpUtils.SuccessfulUrls.Remove(Url)
End If
End Sub
Sub ImagesJobDone
   For i = 0 To links.Size-1' HttpUtils.SuccessfulUrls.Size - 1
      lv.AddTwoLinesAndBitmap(titles.Get(i), links.Get(i),bitmaps.Get(i))
      Log(titles.Get(i) & links.Get(i)& bitmaps.Get(i))
   Next
End Sub

after parsing the XML I need to download the ICONS list and put the PNG to the associated name etc. - but that failed obviously due to the async


any ideas?

You should create a list with all the icons urls and then when the job is done start a new job that will download all the icons.

I thought that is exactly what I do ?

Sub HandleMainPage
   If HttpUtils.IsSuccess(ServerURL) = False Then
      ToastMessageShow("Error loading page.", True)
      Return
   End If
   in = HttpUtils.GetInputStream(ServerURL)
   parser.Parse(in, "Parser")
   HttpUtils.CallbackUrlDoneSub = "ImageUrlDone"
   HttpUtils.DownloadList("ImagesURL", icons)
End Sub

It is impossible for us to know if you don't post the code...

I'm not sure that I understand the problem. If you are trying to do something similar to FlickrViewer example then it should work fine.

Erel,

stripped down version attached

this shows that the numbering is not in the right order…..

[Erel]

What happens after you call: HttpUtils.DownloadList("ImagesURL", icons) ?

 

[madru]

sorry, don't get the question, I the real App. ?

Barker channel will prepared, RTSP client will be prepared, UDP Multicast receiver will be prepared etc.

but the zip version shows the problem already…..

 

[Erel]

I'm probably missing something. However I cannot run your example as it points to a local server.

 

[madru]

the W3 directory inside the ZIP holds all necessary files to run the example, that one needs to be on W3 server

 

[madru]

Erel,

I really need help with this……

[Erel]

I'm sorry but configuring a Http server requires too much work.

I must say that it is still not clear to me what is the problem.

Is the problem that the tasks are completed in a random order?
You should use the Url to match each task.

Erel,

forgot to give you an update :

it was clearly misunderstood from my side, my assumption that the download.list takes card of the right ordering is/was wrong :sign0148:

I solved it this way, not using ImageUrlDone at all :

Sub ImagesURLJobDone
    For i = 0 To HttpUtils.Tasks.Size - 1
        Link = HttpUtils.Tasks.Get(i)
      bitmaps.Add(HttpUtils.GetBitmap(Link))
      lv.AddTwoLinesAndBitmap(titles.Get(i), links.Get(i),bitmaps.Get(i))
      'Log(Link & ": success=" & HttpUtils.IsSuccess(Link))
   Next
End Sub
