B4J Question Determine the end of most jobs

[amaful]

hello
I need some advice ...
I have read html pages every two minutes to extract the information.

Here I prepare the task ..

Dim task As Int=0

    Dim job(tabella.Size ) As HttpJob
    For Each riga As st_tabella In tabella
      job(task).Initialize (task,Me)
      job(task).Download("http://www.miosito.com/" & riga.Nome)
      job(task).GetRequest.timeout=4000
      Log("inizialize job=" & task & " Nome :" & riga.Nome)     
      task=task+1
    Next
    numJob = task

Here are executed.

Sub JobDone(job As HttpJob)
    Dim st As JStringFunctions
    If job.Success = True Then
      Log("JobName = " & job.JobName & " JobSuccess = " & job.Success )
        .
        .
        .
        . 
    Else
      Log("Error: " & job.ErrorMessage)
    End If
    numJob=numJob-1
    If numJob =0 Then
      Log("********* end all job **********")
      .
        .
        .
        .
    End If
End Sub

Unfortunately, I often get timeout errors, which do not allow me to see if the task was completed (numJob <>0).
Is there a way to determine the end of the task? (some event)

It doesn't matter whether the job completed successfully or not. JobDone will be called.

The program includes a reading of about 60 html pages.
With a timer run every 2 minutes reading this.
After the reading I should submit a summary .. If I do not know if I've finished the job ... I can not provide the data.

Maybe I misunderstood the question.

You wrote:

This is incorrect. JobDone will still fire.

 

[amaful]

I have done debugging.
Sometimes I get runtime error, and it seems that the job is not executed, because the variable "numjob" is not decreased, so the condition does not occur "numjob = 0" indicates to me that the end of the readings.

 

[Erel]

Can you post the error you get from the logs?

In JobDone occasionally I get this error in the log:

The question is whether JobDone is raised or not. It should be raised in that case.
