i'm trying to write a function that will open a text file for reading, then read the file line by line and put it into an existing table- graph. i am trying first just to read the lines and past it into one of the table's fields without deviding it to fields.
i wrote:
Private Sub load_Click()
Dim dbss As Database
Set dbss = OpenDatabase("db3") 'db3 is my dbase name
Dim textline As String
Open "a:movefile.txt" For Input As #1
Do While Not EOF(1)
    Line Input #1, textline
    dbss.TableDefs("graph").Fields("num") = textline
    Loop
Close #1
End Sub
the thing is it doesn't work.
the textline format in the file is:
:spo2= (3 digits number) pr= (3 digits number) no probe
if you can please tell me also how to read the file so i can imidiatly past the 3 digits numbers in to diffrent fields in table graph i would give you a very high score.
thank you my saviour.

I think I see what you are trying to do. The code looks roughly like this:


Private Sub foo()

Dim db As Database
Dim rs As Recordset
Dim h As Long
Dim s As String
Dim n1 As String
Dim n2 As String
Dim i As Integer

    Set db = OpenDatabase("db3")
   
    Set rs = db.OpenRecordset("graph", dbOpenTable)
   
    h = FreeFile
    Open "a:movefile.txt" For Input As #h
   
    Do While Not EOF(h)
   
        Line Input #h, s
       
        i = InStr(s, "spo2=")
        n1 = Mid$(s, i + 5, 3)
       
        i = InStr(s, "pr=")
        n2 = Mid$(s, i + 3, 3)
       
        rs.AddNew
        rs.Fields("num1").Value = n1
        rs.Fields("num2").Value = n2
        rs.Update
   
    Loop
   
    Close #h
   
    rs.Close
    Set rs = Nothing
   
    db.Close
    Set db = Nothing

End Sub


Obviously you will need to change the field names to suit. Also, some error handling and a transaction wouldn't go amiss.
