Hmm - New Lines Arent Read As New Lines By Vb In A File
Heres the situation
im using urldownloadtofile to download a text file from the internet onto the harddrive. although the textfile on the net has 5 items, each on a single line, when i use that function the file saves as 5 items all on a single line.. and where a new line is supposed to be, i see a "box" in notepad..

needless to say, when i try to load the file into an array using Line Input, all 5 items are on a single array number, instead of one item in each array number..

heres what i mean..

text file online:
a
b
c
d
e

text file when downloaded to hd:
a[]b[]c[]d[]e

the box is interesting, if i copy the entire text from the file on my hd and paste it, they paste with all 5 items on seperate lines..

my question is, how can i load a[]b[]c[]d[]e with one item in each array with VB? line input wont work cause itll store a[]b[]c[]d[]e in one string

Read Lines And Count Lines From Txt File - Thank Ye All

ive had a quick search on the forums for this but cant find anything that helps, so heres my problem:

i have this code:
Code:
Function random2()
Dim lines As Integer
Dim current As String
lines = 0
    Open "C:files.txt" For Append As #1
    Do While Not EOF(1)
        Line Input #1, current
            lines = lines + 1
            MsgBox (current)
    Loop
    Close #1
txtFILE = lines
End Function

but that code doesnt work, it does count the lines at all, i get no msgbox's, no count, no nothing.

any help would be much appreciated.

thanks.

Loading Lines From A Text File Line By Line
I need to be able to load a line from a text file, perform actions on the line then read out the next line and perform the same actions each time adding the text to a text box, so that by the end the text box will contain all the information from the text file but formatted as to how my code formats it.

My Knowledge of VB is quite limited so explanations of how to use any code posted will probably be needed.

Thanks in advance

Line By Line Text File Read And Correct Each Line
Can anyone help me create a small program or have any pointers
on pieces of code that reads a text file from folder "unfixed" then
fix the contents and then store the corrected contents
in another folder "fixed" and then move the file in folder "unfixed" to folder "old"

Details of contents.
There is a space infront of each line that should be removed.
Between the first group of numbers and the second there should be a zero for every space.
Then after the second group of numbers there should be just one space and the rest trimed off.

011531015222360000500355 3350505212004 50122
011531015222360000500363 5336305212004 6255
011531015222360000503465 2404505212004 50022
011531015222360000503463 1345205212004 50025
02153101522236 13 1503256

The @ symbol represents where a space should be.
I would like to read the file and then correct it and then
place the fixed contents in another folder with the original name.
Below is how I would like it to look.

01153101522236000050035500000003350505212004@
01153101522236000050036300000005336305212004@

Read Line By Line Problem && Question
have a text file that I need to read line by line. This text file is very large (upwards of 1.5GB). The problem with this is that the lines are not separated by normal vbCRLFs but by Unix line feeds which means I can't use the normal Open Blah as #1.

I have tried reading the file in and changing the vbLF to vbCRLF which works for small files and even putting the thing into an array and splitting on the vbLF, but it just won't work. The file is so large that I can't just read the whole thing into memory because it will kill the system.

I know other people may have experienced this because this is an Apache web log and I am hoping someone has some insight or knows of another way or even a custom ReadLine Function that is out there that someone else has built to solve this.

Thanks in advance.

How To Read Text File Line By Line?
Dears Friends,
I am coding a program to read emails.
Is there a way to read the email body text line by line ? if not possible, how can I set the bodytext to a text file and use that text file to read line by line?

Here is my psuedocode for reading email line by line:

With .bodytext
Loop from line 1 to EOF
If line x has string "Hello" then
If line x + 1 has "Money" then
forward this to youare@somewhere.com
end if
end if
End loop
End with

Here is my psuedocode for set .bodytext to file.
dim sFirststring as string
dim sSecondstring as string
With .bodytext
save the .bodytext to a file name A.txt
sFileName = " C:A.txt"
Open sFileName For Input As #1
Do Until EOF(1)
Input#1, sFirststring, sSecondstring
If Mid(sFirststring, 1, 1) = "Hello" Then
If Mid(sSecondstring, 1, 1) = "Money" Then
forward this to youare@somewhere.com
End IF
End If
Loop

How To Read 1st Variable Line By Line From A .txt File
1st question. Is it easier if I use a database I assume?

Say for example I have a file named test.txt which looks like this

"Test1"
"Tst2"
"tt3"

And I do a search for "Tst2" how would I go through file to find that?

Open test.txt for input #1
white not EOF(1)

????

I am totally lost here. And are there any thorough tutorials online for visual basic 6 or a GOOD quality book that would touch on things like this an DBGrid's? The only one I have is too basic.

Thanks in advance and I apologize for the question but I can't find a resolution anywhere.

What's Best Way To Do Read These Lines?
Each day I am going to first create a text file manually like this:

apples 100
oranges 50
peaches 70
...

There will be about 20 lines. I want to read the items into a string variable and the numbers into a long variable. Each variable will be passed to its own procedure.

What is the best way to do this? Just use regular sequential I/O or do I need random access file? Or should I read each line into an array first and then split them? I don't care if I have to use commas or tabs instead of spaces. For example, it's fine if I have to make the text file look like this:

apples, 100
...
or
apples [tab] 100
...

Thanks.

How To Read Certain Lines In A File And Tell What Is Different
Hello,
I have 2 files that I am going to compare. I was wondering how would I go about to read those files, and tell what is different. Take for instance...that file1.txt has <name>Fred</Fred>
<name>Barney</name>
<name>This</name>
File2.txt has...
<name> Barn</name>
<name> Fred</name>
<name> This</name>

Then I would have file box say file2.txt is different than file1.txt.
Because it has more names than than file1.txt and also file2.txt is missing barney.

Can someone tell me of a website that can help me with this, or can they help me themselves?

Read More Lines From Textfil
I'm making a program, were i can store my results from school. The results i put into a textfile called: variable.txt.
Now the program have tot read te textfile, and store each line in an variable.
So each line have is own variable.

But now the problem, i created this code for reading and store the variable:

VB Code:
strFile = "C:Documents and SettingsNilsBureaubladcijfersvariable.txt" 'your file with full path file must exist before you read from it Open strFile For Input As 1 'open text file for reading Line Input #1, strTemp 'read first string to variable Close #1 ec1.Text = strTemp

As you see it opens the file variable.txt, read it and puts the data on line 1 into the variable strTemp. After that the variable is shown in an textbox called ec1.

This works fine, but i have more results, and another result is on the second line in variable.txt. I wanna do the same thing with the secondline as with the first line. Someone knows how i should do this?

How Do I Keep Only The 1st Line In A String Of Several Lines With The Same Name?
Hello there !!!
Say I have this string:

Code:
line1
line2
line*
line*
line3
line5
line77
line*
I think you get the idea

anyways, from the several lines with the same name(line*)
I want to keep only the 1st one of those... meaning, I'll have this in the end:

Code:
line1
line3
line*
line8
line5
line77
BTW - deleting always the 4th&8th lines(those with the same name, but not the 1st ones) won't work cause I don't always know what the user will import and in what order the lines would be.

thx in advance.
