Visual Basic :: How To Read Text And Use It Line By Line

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.

stupid question...tried lookin at the tutorials section;

thx!

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 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.

[Help] Read Last Line Of A Text File
Hey Guys,

Im in the process of trying to make an application and have come to a stand still, unable to find out how to read _just_ the last line of a text file.

The problem is that, instead of loading XXX.txt which could contain 2000+ lines, then getting the last line, causing major overhead, I am trying to find a method for getting just the last line.

Thanks in advance,

Read Last Line Of Text File
Hi Guys,

I needed some help regarding file reading in VB 6. I am writing a program that needs to insert a record in a text file. The text file has following format..

Date, Time, Open Price, Close price

Now i need to insert record only if date is greater than last date in file.

So everytime I need to insert record, I have to open file and read sequentially and then I reach last record. This takes time.

IS there a way to read such file in binary or whatever so that i can get last record straight away or very quickly without going thru all records one by one.

If there is can anyone post a small code.

[Records in the (text) file is like -

01/01/2006, 1100, 123.33, 155.55
01/01/2006, 1130, 122.22, 134.33
01/01/2006, 1200, 112.22, 124.33
so on ... ]

Thanks a lot,

Cheers,

VB Code:
Dim sFileText as StringDim iFileNo as Integer iFileNo = FreeFile 'open the file for reading Open "C:Test.txt" For Input As #iFileNo'change this filename to an existing file! (or run the example below first) 'read the file until we reach the end Do While Not EOF(iFileNo) Input #iFileNo, sFileText 'show the text (you will probably want to replace this line as appropriate to your program!) MsgBox sFileText Loop 'close the file (if you dont do this, you wont be able to open it again!) Close #iFileNo

I have managed to get it too display the .txt file in a Textbox running from a command button.

But as the text file has mulitple lines it reads and displays the last line of the text file.

I want to find a line of text in the .txt file and display that.

First program so..

Read Random Line From Text-file
Hi!

I want to read a random line from a text file. My text file has 315 lines in it. Here is what I have written so far:

Code:
Dim number As Integer
Dim line As Integer

number = Int(300 * Rnd) + 1
Open App.Path & "words.txt" For Input As #1
For line = 1 To number
Input #1, line
Next
MsgBox (line)
Close #1

But every time I try to run this, the debugger informs me about Run-time error '62': Input past end of file.

The problem can't be with the randomizer because I checked the output once and it said that the number was 8. And since my text-file is 315 lines long, I really can't figure what is the problem.

Can anyone help me?

Read From A Text File One Line At A Time
Sorry to revive an old thread but its probably better then adding a new one

Im using a code to download a file and then read from that file, the file downloads OK, all the text in the downloaded file is correct but this code doesnt seem to be working

Code:
intFile = FreeFile()
Open CurDir & "
otice2331.dat" For Input As #intFile
Line Input #intFile, strLinenews1
Line Input #intFile, strLinenews2
Line Input #intFile, strLinenews3
Close #intFile
it works if i use just the Line Input #intFile, strLinenews1, if i put the other 2 i get a Input past end of file, but im sure the file has more then 3 lines.

Any idea whats wrong?
