Hi Guys,

I have issue when I want to get to the last row on last page in attachmate extra. I can see that last character is on page 2, line 13. When i do MsgBox Sess0.screen.getstring(13,1,60) it will output correct characters.
But when I use 14th line :MsgBox Sess0.screen.getstring(14,1,60) I will get result which is actually on the previous page on that line.

Is there anything i can do to get only characters that are visible on current page?

PS: MsgBox is the only code that I have in macro

Thanks

Hi,

All your emulator "sees" is what's on the screen. You are scraping characters off the data displayed in front of you.

On the first picture you can see that i`m on page 2 and
MsgBox (Sess0.screen.getstring(15,1,15) will output something that is not there

on this screen you can see that what was shown by MSGBox is on previous screen

CODE --> VBA

Sub Main()
'--------------------------------------------------------------------------------
' Get the main system object
    Dim Sessions As Object
    Dim System As Object
    Dim Host As Object
    Set System = CreateObject("EXTRA.System")    ' Gets the system object
    If (System is Nothing) Then
        Msgbox "Could not create the EXTRA System object.  Stopping macro playback."
        STOP
    End If
    Set Sessions = System.Sessions
 
    If (Sessions is Nothing) Then
        Msgbox "Could not create the Sessions collection object.  Stopping macro playback."
        STOP
    End If
'--------------------------------------------------------------------------------
' Set the default wait timeout value
    g_HostSettleTime = 3000        ' milliseconds
 
    OldSystemTimeout& = System.TimeoutValue
    If (g_HostSettleTime > OldSystemTimeout) Then
        System.TimeoutValue = g_HostSettleTime
    End If
 
' Get the necessary Session Object
    Dim Sess0 As Object
    Set Sess0 = System.ActiveSession
    If (Sess0 is Nothing) Then
        Msgbox "Could not create the Session object.  Stopping macro playback."
        STOP
    End If
    If Not Sess0.Visible Then Sess0.Visible = TRUE
    Sess0.Screen.WaitHostQuiet(g_HostSettleTime)
    
'--------------------------------------------------------------------------------

        
        
MsgBox  Sess0.screen.getstring(1,76,1)   
MsgBox  Sess0.screen.getstring(15,1,15)  


 

End Sub

What happens if you add to 15 the number of rows on a screen. So if your screen if 16 rows...

CODE

MsgBox  Sess0.screen.getstring(31,1,15)
