Maybe this will help.

In this case the input text is read from a disk file. Instead of having control characters it has $, <, and > characters... just for demonstration.

I bro... sory for delay, but busy in a big project.

is this correct to find and remove chr$(12) and Chr$(26)...

Const TO_BE_FILTERED As String = "Chr$(12)Chr$(26)"

tks.

It should read:

sal21

... Not sure your suggestion work.
Tksin other case for code.

Chr() does not work for Const in VB6 (but fine in VB.Net). Here is a discussion:
[RESOLVED] Constants for ASCII Control characters?-VBForums

Another option might be to just load the values into a Dim string variable when Sub Main is loaded:

sal21

OK I use
Dim TO_BE_FILTERED As String
TO_BE_FILTERED = Chr$(12) & Chr$(26)

and the code wotk fine untill

DataIn = Input$(LOF(F), #F)

have error: out of string space error 14

my file is approx 140 mb, with fixed lenght of each line 132 byte

solution?

Flyguy

This error has nothing to do with the filter string.
You should not read such a big file in a single string.

Can you explain again what kind of data the file has.
Is it a text file, from which you want to strip certain characters?
Or is it a binary file with special line separators?

dilettante

Well he said he has fixed 132 character lines. However so much else is left unsaid it is hard to know where to begin.

Are there record delimiters or not? If not and this is truly fixed records are they padded with spaces on the right? NULs?

Character encoding? ANSI, ASCII, UTF-16LE, UTF-8, etc? If ANSI do you need to deal with LCID/CharSet or are the characters encoded for your locale?

What does "read line by line" mean? Read each line as a String for the program to do something with? Do you really want to read all of this bulky file, or are you trying to reformat it as a new file for some other application to accept?

What about those control characters? Strip them, replace then by spaces, or...?


It sounds like a printer file produced by a terminal emulator, but that doesn't tell us much without specific details.
