RE: Catch lines screen Extra


Where are you writing and executing your VBA code?

RE: Catch lines screen Extra

I am writing and executing in Extra macro editor.

RE: Catch lines screen Extra

Please post your code.

RE: Catch lines screen Extra


Global g_HostSettleTime%

Sub Main()

Dim Sessions As Object
Dim System As Object

Set System = CreateObject("EXTRA.System")

If (System is Nothing) Then
Msgbox "Error macro 1."
End If

Set Sessions = System.Sessions
If (Sessions is Nothing) Then
Msgbox "Error macro 2."
End If

g_HostSettleTime = 3000
OldSystemTimeout& = System.TimeoutValue
If (g_HostSettleTime > OldSystemTimeout) Then
System.TimeoutValue = g_HostSettleTime
End If

Dim Sess0 As Object
Set Sess0 = System.ActiveSession
If (Sess0 is Nothing) Then
Msgbox "Error macro 3."
End If

If Not Sess0.Visible Then Sess0.Visible = TRUE

Dim MaxCols as Integer
MaxCols% = Sess0.Screen.Cols

Dim MaxRows as Integer
MaxRows% = Sess0.Screen.Rows - 3

Dim Buffer as String
Buffer$ = ""
Dim LineBuffer as String
LineBuffer$ = ""
Dim NumLin as String
NumLin = "000000"

Dim Lin as Integer
Lin% = 4


FNum% = FreeFile
Open "C:\file12.txt" for Output as FNum%

LineBuffer$ = Sess0.Screen.GetString (Lin%,1,MaxCols%)
If Right$(Trim$(LineBuffer$),3) = "END" and Right$(Trim$(LineBuffer$),5) <> "DOEND" Then
Buffer$ = Buffer$ + LineBuffer$
Print #FNum%, Buffer$
Exit Do
End If
If Lin% Mod 23 = 0 Then
Buffer$ = Buffer$ + LineBuffer$
Print #FNum%, Buffer$
Lin% = 4
NumLin$ = Left$(LineBuffer$,7)
Buffer$ = ""
If Val(Left$(LineBuffer$,7)) > Val(NumLin$) Then
Buffer$ = Buffer$ + LineBuffer$ + Chr$ (13) + Chr$ (10)
End If
Lin% = Lin% + 1
End If


MsgBox "File: C:/file12.txt"

SystemY.TimeoutValue = OldSystemTimeout
End Sub

RE: Catch lines screen Extra

I'd fix errors before trying to RUN.

SystemY.TimeoutValue = .......

What is SystemY????

There may be other syntax errors.

I almost NEVERTHELESS code in Extra. In my line of work I'm scraping data from the mainfram terminal emulator, to get it into Excel for analysis. So I do nearly ALL my coding in Excel VBA. Excel has a much MUCH better code editor.

RE: Catch lines screen Extra

I liked the tips.
thank you for help.
