    Re: extract specific data from txt file

    you can try like
    Code:
    Open "c:\temp\card2.txt" For Input As 1
    scard = Input(LOF(1), #1)
    Close 1
    pos = 1
    Do
        pos = InStr(pos, scard, "DATE-TIME")
        If pos = 0 Then MsgBox ("no more transactions"): Exit Do
        pos2 = InStr(pos, scard, "TRANSACTION END")
        If pos2 = 0 Then MsgBox ("no transaction end"): Exit Do
        stran = Mid(scard, pos, pos2 - pos)
        pos = pos2
        adetails = Split(stran, vbNewLine)
        dt = Mid(adetails(0), 13, 17)  ' parse the date detail from array
        ' all details for one transaction should be in the array adetails
        ' here you need parse the required items from the array to assign the values to your database
    Loop
    this would not work for your previous sample of file as no transaction end
    i do my best to test code works before i post it, but sometimes am unable to do so for some reason, and usually say so if this is the case.
    Note code snippets posted are just that and do not include error handling that is required in real world applications, but avoid On Error Resume Next

    dim all variables as required as often i have done so elsewhere in my code but only posted the relevant part

    come back and mark your original post as resolved if your problem is fixed
    pete
