How Do I Read A SPECIFIC Line From A Text File ?? GURUS PLEASE HELP =)
A few easy questions for you gurus =)

2. How would i read a specific value in a text file? Lets say the file looks like an ini file:
thing1=value1
thing2=value2

How would i read/write from the specific value?? PLEASE HELP!!!!
Is it possible to search for a string in a file without loading it in a textbox? How would i then extract the value of thing2 for example then???

How Would I Read A Specific Line From A Text File As A String?
I would like to read configuration from a text file like config.txt
each line would look like: variable value (for example: version "0.9")

How would i find the variable and read it's value ????

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.

Reading A Specific Line In A Text File?
Hi all,

I have done a search on reading text files and have not found exactly what I am looking for. Most people what to read 1 line at a time to a text box or read the last line of a text file.

I am trying to write a programme that will give me the best flexibility to produce different size out put prints (from jpegs) when it is finished, but I need help on reading text files.

When printing I can use the paint picture method with no problems and define my out put. What I am looking to do is create a print products folder in the app path, with different text files representing what I want to print. With a structure something like this set out in a text file called “8x10.txt”

Bitmap: 8x10.bmp
High: 8 (or 11520 twips)
Wide: 10 (or 14400 twips)

Then if I want to add a “5x7.txt” there would be a 5x7 option to print also. I know I could use a filelistbox to list my different options, but how do I open a text file and use what are on the different lines to fill in my variables?

Dim PrntHigh as Integer ‘ height of the print
Dim PrntWide as Integer ‘ width of the print

PrntHigh = line 2 of the text file
PrntWide = line 3 of the text file

Any help is greatly appreciated as always.

Regards Tom

Access Specific Line From Text File
Hi,
I need to read text line by line from a text file. I have the following code:

Open "rollup.txt" For Input Lock Read Write As #1
Do While Not EOF(1)
Line Input #1, record
A() = Split(record, ",")
.......
Loop

The code functions as it should; my problem is that the text file is 3 MB in size, and over time, it's size will increase. It currently takes over an hour for the program to process on a 3.6 MHz machine! I need a way to optimize the code as much as possible.

I know there are portions of the data that I can skip. My question: is there a fast way to jump to a specific line in the text file? Can I do so without parsing through every line and storing it in a buffer?

Thanks in advance for all your help!

Writing To A Specific Line In A Text File.
How can I overwrite line one of a text file, but leave the rest of the text file in place?

Is it possible, or will I have to fake it by loading the whole file after line one into the program, then writing a new file with the new line one, and then the rest of the file after?

Reading Specific Line From A Text File In Vb 6
hi guys
have a look at this code

Code:
Open "C:Score.txt" For Input As #1
Text1.Text = Input$(LOF(1), #1)

lblX.Caption = Text1.Text
lblO.Caption = Text1.Text

the score text file contains the following

Code:
2
3

when i run the program, and load the file, the lblX and the lblO
both display everything in the text file

but i would like the lblX to display the first line in the text file ie: 2

and the lblO to display the second line in the text file ie: 3

so how can i do this?

Jump To A Specific Line In A Text File
Hi,

I have a huge text file that I need to read a specific line. The file has 5671 rows and 7743 columns, so it is too big to put into an array quickly. I know which row that I want to read, but I only know how to read from the first row down, so by the end it takes forever.

Here is the code:

aDEMFile = "C: empdem300ft.txt"
iFileNum = FreeFile
Open aDEMFile For Input As iFileNum

'if the position to go to is ahead of the current
'pointer, then move ahead to that position.
If Yposition > tempPosition Then
For i = tempPosition To Yposition - 1
Line Input #iFileNum, str
tempPosition = tempPosition + 1
Let Position = tempPosition
Next
...

Can you jump to a specific record?

Is there a better way?

Or can I easily load this into an array? (it takes forever to load into the array now)

Thanks, Chris

Need Way To Look At Specific Line In Text File. Tricky
Anyone know of a good package that will open a text file and display the line number you are looking at????? Be great if it was free (Not to the programmer though)???

I have a text file with 100,000 records. I try and pull it into a SQL server but it errors out and gives me the line number (83,001). However, I do not have a way to look at that line to see what the problem is. I had someone with AS400 access pull the file in and for some reason the AS400 will do it and not error. He looked at line 83,001 and it indeed had a problem with respect to bad quote marks. I want to be able to fix the problem myself rather than having him take this step every week when a new text file arrives. I am looking to correct the text file at the source but would like a fix in the mean time.

If I try and use the LINE INPUT function it can not open file and errors out. I believe because it is to large.

Thanks

Read Specific Line
Hi,
In my current project I need to load ever first and every fifth text line (from a txt file for example) to 2 textboxes

However the current code I use only allows me to but all the 10 lines to 10 texboxes and use it after that.
So as far as I know this code is only usable to load either every line to a seperate textbox, or to get the first line from a text file

My current code is:

Private Sub File1_Click()
Open File1.Path + "" + File1 For Input As #1
Line Input #1, a1
Line Input #1, b1
Line Input #1, c1
Line Input #1, d1
Line Input #1, e1

Text1.Text = a1
Text2.Text = b1
Text3.Text = c1
Text4.Text = d1
Text5.Text = e1
End Sub

Hope you can help

tnx in advance,

Maartuh03

Read Specific Line
Hello,

I'm looking at writing a password generator that uses real words. In order to do this I've downloaded a relatively small dictionary text file, about 80K words (600kb), with a word-per-line.

Now, my problem is what is the best way to pick a word out of this file randomly, preferably with FSO?

Currently I count the number of lines in the file and use a random number generator to pick a number within the lines-of-file range. This is where I run into problems/issues. I can read each line into an array, and access the random element as required, but is this the best/most efficient way for such a large number of lines?

Thanks.

[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.

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,
