Visual Basic :: Read Specific Line

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,

Read Specific Line Of Multiline Textbox?
I've only been working with VB for a very short time. I'm trying to read a specific line of a multiline text box. For example, I wish I could do something like this:

Dim Line4Data

Line4Data = txtBox.Text (line = 4)

Is there an easy solution to this? Everything I've read starts talking about SQL databases and blows my mind.

Thanks.

How To Read A Specific Http Link On A Specific Page And..
Hello ppl!
I am a REAL newbie to VB and I am trying to do a simple thing (I hope) I have no real basecode just the one to open a specific link: Code:

Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

Private Sub Form_Load()

ShellExecute 0, vbNullString, "http://play.mp3.com/cgi-bin/play/play.cgi/AAIBQgAAAADABG5vcm1QBAAAAFLeTgEAUQoAAABYAQAAAFneTgEAQ2.J0TwUhHw6YJu97A3gU7XcOVum/fuzytoes.m3u/", vbNullString, vbNullString, vbNormalFocus
Unload Me

End Sub
Now, Id like to add some functionality since MP3.com changes the links every now and then. I need the program to go to the page, snatch the new link and then use it to open, say winamp. BTW, IE 5.5 does not alway's respond to the code above.. Dunno why. Sometimes it does. sometimes nothing happends whatsoever. Strange!

Ideas? Perhaps not a whole solution cause then I'll not learn. Thanx in advance! /FuzyToes

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@

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

Thanks,

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.

Specific Line Only
I've done a search of the forum and found a mix of replies, but not one that seems particularly usefull. I'm wondering if there is a command to read only the specific (last) line of a text file. Btw, its for a highscores table containing exactly 15 entries, I want to read the last line in to compare to the new score. I know it can be done with *.ini file, but not sure this would be the best method for this. Obviously with only 15 files I could simply read in the whole lot each time, but figured I might aswell try to learn something new while I'm trying.

Any intelligent suggestions welcome. Cheers.

Go To A Specific Line In A File
I have different files of all sorts, and I wish to go to the end of the first line, insert a carridge return and line feed. Then insert a string variable and save the file to its original name.

I can't just do a string comparision, because the files will always be different. How can I do this?

Basically, I want to find a specific location in any file.
ie. nth line xth column

Thank you.

How Do I Tell This Line To End In A Specific Spot??
The following code creates a random wavy line.

Code:
Private Sub Timer1_Timer()
Me.Cls
segments = 20
X1 = 100
Y1 = 300
X2 = X1 + Int(Rnd * 20) + 1
Y2 = Y1 + Int(Rnd * 10) - 5
linelength = 300
For t = 1 To linelength / segments
Form1.Line (X1, Y1)-(X2, Y2)
X1 = X2
Y1 = Y2
X2 = X2 + linelength / segments
Y2 = Y2 + Int(Rnd * 10) - 5
Next t
End Sub
as you can see in the code, the line has a fixed start point.
The problem is, it's end point is not fixed. it jumps around like a string being blown in a breeze.

I'm going to use code similar to this to make a 'BumpyLine'
function that I can use to draw realistic coastlines for
random continents. so being able to set a fixed end point is important.

Any help would really be appreciated.

Read File From Specific Point To The End??
I am attempting to read a file and write what I read to the end of another file. My problem is that I do not want to read the first part of the file I am reading. I need to find a "keyword" which tells me where to start reading and writing the information to the other file. Here is my code.... this code opens one file for reading and then writes the whole file to the end of the other file?

Do I need to do this line by line to accomplish what i need? The problem is the file i am reading is an extremely long html file.

dim fso as new FileSystemObject
Dim file as file
dim filetocopy as file
dim textstream as textstream
dim newTextstream as textstream

Set file = fso.GetFile(MyfilePath.html)
set filetocopy = fso.getfile(MyFileToCopy.html)
set textstream = file.OpenAsTextStream(ForAppending)
set newTextstream = file.OpenAstextStream(ForReading)
textstream.write newtextstream.readall
textstream.close
newtextstream.close
set file = nothing
set fso = nothing

Any suggestions

Thanks,

M
