Question

Using VB, a text line read in is not yielding correct record length ... any ideas for this newbie?

Asked by: bhindbjorgen

I am reading in a file containing records of variable length ... some of which are quite long (over 4096 characters).  For these records, I am wishing to handle differently than those that are less than 4096 characters in length.  The problem is with the Len().  It is not yielding the correct length for me on these long records.  I am attaching code and input file.  
Thanks in advance.  Brad.

FileToDelete = ("WCR-PreSort.txt")
    
    If objFSO.FileExists(FileFolder & FileToDelete) = True Then
        Dim objOutputFile
        Set objOutputFile = objFSO.CreateTextFile(FileFolder & FileToDelete, True)
        objOutputFile.Close
        objFSO.DeleteFile (FileFolder & FileToDelete)
    Else
        ' MsgBox "Msg from Form's VB Code ... File(s) do not exist."
    End If
 
    Dim SourceNum, DestNum, RecLength As Integer
    Dim ReadLine, strText As String
    
    SourceNum = FreeFile()
    Open "C:\Case Reports\Access Data\WCR-Merged2.txt" For Input As SourceNum
    
    DestNum = FreeFile()
    Open "C:\Case Reports\Access Data\WCR-PreSort.txt" For Append As DestNum
    
    Do While Not EOF(SourceNum)
    Input #SourceNum, ReadLine
    RecLength = Len(ReadLine)
    If RecLength > 4095 Then
        strText = "Due to content length, this text cannot be viewed here."
    Else
        strText = ReadLine
    End If
    Print #DestNum, strText
    Loop
 
Exit_RunCommandPreSort_Click:
    Close #DestNum
    Close #SourceNum
    
    Exit Sub

Raising Points to 500.  I didn't think that the answer would be so difficult, but maybe it is.
Anybody have any ideas whatsoever?

Try ReadLine.Length as Len() might be returning the bytes required to store the variable instead of characters.

You must have something else wrong. If you send me the actual code at technofyle@yahoo.com I will be happy to look. If you have specific proprietary stuff you can leave that out but i might not be able to solve the problem if you don't send enough.

 

by: bhindbjorgenPosted on 2009-09-03 at 07:23:43ID: 25250974

the code and file are all here, but I will be happy to send them to you.
I will send them later this afternoon when time permits.  thanks much.  Brad.

I (see note) determined that the problem was with the line of VB code ... Input #SourceNum, ReadLine
The VB line of code should be ... Line Input #SourceNum, ReadLine
This reads the entire line in.
When using Input #SourceNum, ReadLine ... it uses any comma in the line as an end-of-record situation.
My text has commas all over the place.
NOTE:  Sorry Technofile.  
Credit would go to Idle_Mind from Question w/ Title: Title:
VB6 Input command problem with commas.
I do appreciate the time, in any case.
Thanks again.  Brad.

If you are using VB6 I understand now. If you are using vb.net I would really appreciate it if you sent me a copy of your code because some of this stuff really didn't make sense. VB6 would totally explain everything because I only used it for a short while and it was about 10 years ago.
