Line Input Method

[Trevor Fairchild]

Hello, all.

I am writing a program that parses an html report (generated by
another program).

I use the Open "C:\...." for Input As myValue method to open
the html, and read through it line by line, using "Line Input
#myValue, myLine" to do so.

My problem is that there are, occasionally, unusual Unicode characters
in the report. When the Line Input method hits a line with one of
these square-looking characters, it interprets it as an End-Of-File
marker. There is more information after it but VB refuses to access
it.

I cannot force another Line Input, and cannot even have a Mid()
function read any of the characters beyond this unicode character.

Does anyone have any ideas/suggestions on what command I can use to
trap this type of event? I was thinking I could use FileLen() to
identify how large the file is, and then compare it against a running
tally of the size of each line and say that, if fileLen >
runningTally, force past the current character.

Any help would be appreciated.

That would be highly unusual ... The *only* character that's interpreted as
an EOF is CTRL-Z.
There is more information after it but VB refuses to access it.

... which is half of what you are supposed to do :-)

1) Open the file "for binary: instead of "for input"
2) Replace the "eof(MyValue)" with "(not seek(MyValue) < lof(MyValue))"

That should be all ...

I had tried the binary on this issue and it didn't work - each time I
try to read the line, it only comes back with a portion of it...
I can't get into too much detail, but the program that makes this
report goes through a harddrive and rebuilds folder structures from
Unallocated Clusters - because these are folders that had been deleted
and now rebuilt, they are not always intact, and, as such, non-ascii
characters appear where the folder name cannot be 100% reconstructed.
I have put a sample of the character issue:

partsᨀ\00000001.did<br>

it is the square, after parts that is the problem.

When I use the Binary method, myLine only reads as "ÿþp" - I don't
know where the two other characters come from...
If I use the Input method, myLine comes out as "ÿþparts"

I can't even get VB6 to read that square - if I could, then I could
have it ignore it, or something...

even as I look at my message post, I see the square has been replaced
with

lol, you'll hve to trust me, though, it looks like a square on my
side, and even in my message - I guess Google groups, or Internet
Explorer changed it after I submitted it - it was a square.

In binary mode you get all the data, no lines. You have to parse
the data manually to break it up in any meaningful way. If you're
lucky, you might get End Of Line characters to help you, but don't
count on it.

Data in any file, is simple data, why didn't binary access work for
you?

Unicode is not really supported on the Web
