Keep Alive Timer

Keep Alive Timer

Keep Alive Timer

(OP)
I am more familar with the basic macro language of kea! or aspect in procom, but am stuck with using EXTRA! 7.11 on this task, and am having trouble writting a basic keep alive timer.

I just need to send a "R<ENTER>" every 2 minutes if the screen does not refresh.

I tried to record a macro and mess around with the WaitHostQuiet, but cant figure out how to loop it forever.   

RE: Keep Alive Timer

What are you trying to accomplish by keeping your connection alive?

CODE

Declare Sub Wait(Sess As Object)

Sub Main()
   Dim Sys As Object, Sess As Object

   Set Sys = CreateObject("Extra.System")

   If Sys Is Nothing Then
      MsgBox ("Could not create Extra.System...is E!PC installed on this machine?")
      Exit Sub
   End If

   Set Sess = Sys.ActiveSession

   If Sess Is Nothing Then
      MsgBox ("No session available...stopping macro playback.")
      Exit Sub
   End If
   
   Do While (1)
      Sess.Screen.SendKeys ("R<ENTER>")
      Call Wait(Sess)
      Sess.Screen.WaitHostQuiet (3000) '   3000 <- 3 seconds
                                       ' 120000 <- 2 mins
   Loop
   
   Set Sess = Nothing
   Set Sys = Nothing
End Sub

Sub Wait(Sess As Object)
   Do While Sess.Screen.OIA.Xstatus <> 0
      DoEvents
   Loop
End Sub

Thanks a bunch, nice to know the right way to do it, previously in KEA!420 I would just loop two different macros against each other, another feature left out of Extra!.

RE: Keep Alive Timer

Sorry, I didn't see your question in the solution. It's not really a "keep alive" timer, as much as it is a screen refresher. The program that I am accessing doesn't realiably refresh the data on a specific interval, but will refresh if manually keyed.
