Parsing Text File

I am trying to parse a text file in Visual Basic 6.
These are the steps that I am taking:

1. Open the input file for reading.
2. Open the output file for writing.
3. Read one line from input file.
4. Parse this line and filter out non-printing characters.
5. Write the line to the output file  

I need help on step 4.

what do u mean by non-printing characters
What is a non-printing character?  One whose ASCII values falls outside of an acceptable range?  If its that simple, then you should be able to do something like:

For i = 1 To Len(strLineInput)
    If Asc(Mid(strLineInput, i, 1)) < 255 Then
        strLineOutput = strLineOutput & Mid(strLineInput, i, 1)
    End If

Print #1, strLineOutput

strLineOutput = ""

I really had no idea so I just threw up the first "border" number that came to mind.  You're right though, other than Unicode characters, anything under 255 would include the entire ASCII table.
fh2Author Commented:
Non-printable characters are characters from 0 to 31 and 127 in standard ascii table.
fh2 ,
Check out the ascii values and decide what you wish to keep and what you wish to replace

you can remove the characters with something along the lines of

strLine = Replace(strLine, Chr(7), "")   'Removes "Belll"

If thats the case then Azra's code will work for you with only a slight modifications
