Import EDI file into Access line by line - vba

Question

I need to import into Access table this EDI text file ( ' as line terminator):
UNA:+.?'

This is the result I need:
0089430043 05/02/2018 46550705 AL7B009435
0089430043 05/02/2018 46550705 AL7B009438
etc...
and this is what I tried:
Public Function import1()
Dim strFilename As String: strFilename = "C:\despatch.txt"
Dim strTextLine, CodProd, DataDoc As String
Dim SNarray() As String
Dim NumDoc As Long
Dim nPAC, NumRig, intCount As Integer
Dim iFile As Integer: iFile = FreeFile
Open strFilename For Input As #iFile
Do Until EOF(1)
Line Input #1, strTextLine
strTextLine = Replace(strTextLine, "'", "")
'BGM
If Left(strTextLine, 3) = "BGM" Then
NumDoc = Mid(strTextLine, 9, 10)
End If
'DTM
If Left(strTextLine, 6) = "DTM+11" Then
DataDoc = Mid(strTextLine, 14, 2) & "/" & Mid(strTextLine, 12, 2) & "/" & Mid(strTextLine, 8, 4)
End If
'CPS = numero record
If Left(strTextLine, 3) = "CPS" Then
NumRig = Val(Mid(strTextLine, 5, 3))
End If
'PAC = numero di matricole da estrarre
If Left(strTextLine, 3) = "PAC" Then
nPAC = Val(Mid(strTextLine, 5, 3))
End If
'GIN
If Left(strTextLine, 3) = "GIN" Then
'strTextLine.MoveNext
End If
'LIN
If Left(strTextLine, 3) = "LIN" Then
CodProd = Mid(strTextLine, 8, 8)
End If
'strTextLine.MovePrevious
SNarray = Split(Mid(strTextLine, 8), "+")
For intCount = LBound(SNarray) To UBound(SNarray)
Debug.Print NumDoc & " " & DataDoc & " " & NumRig & " " & CodProd & " " & SNarray(intCount)
Next
'strTextLine.MovePrevious
'strTextLine.MovePrevious
Loop
Close #iFile
End Function
Before to import GIN record with serial numbers, I need to achieve the LIN record with che product code, and then pass them to variables.
I've tried with .MoveNext and then with two .MovePrevious but it gives me error: object needed.
Any help would be appreciated.
Thanks.

Answer 1

This is an example of a function that parses an EDIFACT segment, it's not debugged but it shows the algorithm to read the EDI data. It can be easily adapted to read ANSI X12.
Function GetLine() as String()
Dim Elements as String(99,3)
Do Until EOF(1)
mychar = Input(1, #1) ' Get one character
If mychar = vbCr Or \
mychar = vbLf Then ' Skip Line Breaks
Continue
Else If mychar = "?" Then ' Process Escape
If EOF(1) Then Exit Do ' Reached end of file
mychar = Input(1, #1)
data = data & mychar ' Treat next char as regular
Else If mychar = "'" Then ' End of Segment
Exit Do
Else If mychar = "+" Then ' Element separator
Elements(Elem,Comp) = data
data = ""
Comp = 1
Elem = Elem + 1
Else If mychar = ":" Then ' Composite separator
Elements(Elem,Comp) = data
data = ""
Comp = Comp + 1
Else ' Regular data
data = data & mychar
End If
Loop
Elements(Elem,Comp) = data
GetLine = Elements
End Function
Example use
'BGM
If Elements(0,0) = "BGM" Then
NumDoc = Elements(2,1)
End If

Answer 2

Finally I solved (I really don't know how I did), here my code:
Function GetLine() As String()
Dim FSO As Object, objFile, objFolderIN, objFolderOUT As Object
Set FSO = CreateObject("Scripting.FileSystemObject")
Set objFolderIN = FSO.GetFolder("C:\IN")
Set objFolderOUT = FSO.GetFolder("C:\Archivio")
Dim data, elem, comp
Dim i As Integer
Dim iFile As Integer: iFile = FreeFile
Dim Elements(99, 3) As String
Dim mychar As String
Dim NumDoc As Long
i = 1
For Each objFile In objFolderIN.Files
Open objFile For Input As #iFile
Do Until EOF(1)
Line Input #1, data
'Debug.Print data
mychar = Input(1, #1) ' Get one character.
If mychar = "'" Then Exit Do ' End of Segment
If mychar = vbCr Or _
mychar = vbLf Then
'Continue
ElseIf mychar = "?" Then
mychar = Input(1, #1) ' Skip Line Breaks and Escape
data = data & mychar
ElseIf mychar = "'" Then
Exit Do
ElseIf mychar = "+" Then ' Element separator
Elements(elem, comp) = data
data = ""
comp = 1
elem = elem + 1
ElseIf mychar = ":" Then ' Composite separator
Elements(elem, comp) = data
data = ""
comp = comp + 1
Else ' Regular data
data = data & mychar
End If
Loop
Elements(elem, comp) = data
GetLine = Elements
Close #iFile
i = i + 1
Next objFile
'BGM
If Elements(0, 0) = "BGM" Then
NumDoc = Elements(2, 1)
Debug.Print NumDoc
End If
End Function
