Get Number Of Lines From File?
May 23, 2012
how or what to do but I am trying to get data from a file. The file contains multiple lines, each lines represents a customer. the line is broken in this parts Quotealeks-1234 a street-CDA-ID-12345 then that is broken in name address city state(combo box)zip
Public Sub ReadFromFile()
Using fs As New FileStream("customer.txt", FileMode.Open, FileAccess.Read, FileShare.ReadWrite)
[Code]....
that is the code I am using to get each field in it's array. I am not quite sure how to get the number of lines so I can make it work properly. I also attached the whole project.

Is there a way to see how many lines are in a text file? This also includes blank lines. I have seen a lot of code in this forum before related to my question, but they stop if there is a blank line. I want it to be so that if there are like 10 blank lines

Basically, every time an entry is made - all of the proper data gets put out to a central Listings.txt file and then a specific .txt file for that area. When the user enters the recall form, they can view the listings for all or whichever area they've selected. That works quite fine. However! We also need to include a summary of how many are in each section. Not thinking properly, I started to do this with a counter - until I realized that a counter will lose its value once the program shuts down. My current idea is to count the number of lines in the text file (it outputs 8 lines per listing, so everything would be in values of 8) and then divide that by 8 - but after some searching I haven't been able to find a piece of code that will allow me to get an integer that relates to the amount of individual lines in the file.

Im making a text based game that i need to randomly select different numbers of lines from a text file then pass them to a list box.[code]...
First the code needes to identify the 4th element then randomly select lines from lines that contain that element. The code needs to work out how many lines have a matching text to the 4th array then randomly select lines from that total no need for a maximum limit to that number.The same line must only been show the once at a time, but It can then be shown again on a different button click.[code]...

As you will see from the code below I need to be able to tell before the array runs how many members of the array there are or else the program will crash. How can I redim the array depending on how many lines are in the text file (RECORDS.txt)

Public Class Form1

I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..
Dim ary() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then
[code]....
The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

I have a number of lines of text on an .aspx page that I want a user to be able to edit, I am not storing this text/information anywhere in the database. I just want it to be information that is displayed to the user but can be editable, so the user can view the text and if there is a mistake or want to make a change they can do this by editing it.
I have seen that if you display data in a label and put a textbox beside it then, the textbox can move into the place of the label - I have done this for other text on the page however that method would not fit for this purpose because I require this edit of text to be for a number of lines.

I am hoping that someone can help me with a problem I've got at the moment using Compact Framework.Net 2 SP 2.At the moment I have a UI with a series of text boxes and each textbox displays the contents of a database field. These are shown one beneath another with a scroll bar on the right hand side of the form. Each textbox has a set width which might.I would like to adjust the height each text box based on the number of lines it is holding, the font size and the font in order to avoid using scroll bars on each textbox.[code]

I have read a text file into a textbox. The text looks like this (small snippet):
N08861 A1 P 0 A2 P 0 A3 P 0
N08862 P 0
N08870 P 0
N08900 P 00000001
What I want to do is to only display certain lines - this depends on the N number shown above.
E.G. I want the text box the display line N5000 upto N6000.

As Strings.Space Method , but instead space - new lines.For example:If I want 4 spaces, I can do:
space ("4")
But if I want 4 new lines,I have to do?:
VbNewLine & vbNewLine & vbNewLine & vbNewLine
Or there is another way and more effective? (such as "Strings.Space Method"for example)

I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

I am trying to design a report where one filed can be multiple lines and the other related field should be located below (See attached)
address may be 1 one or more lines, city state zip should be located just below.
I already have the field set to can grow, however the spacing is the issue. How do I make the spacing adjust at runtime depending on the number of lines in the field. I can space it to say 3 lines, but if the address filed is only 1 line it leaves a 3 line gap.
