Read Textfile Lines And Put It In Different Label?
Feb 27, 2011
I have a txt document here that have certain word on it per line. How can I show it in different labels. I have 25 labels and have label name as followsword1,word2,word3,word4,word5 and so on up to word25. I want the word 1 label will show the first line of the text file and the second word2(label name) will show the second line of the textfile and so on up to the 25th line . Can it be done using loop?I tried but I dont know exactly how readline process works to identify certain lines you want to read and also I tried using the "i" variable to auto generate the name of my label but it did not work.
Dim timepath As String = "C:ACCOUNTSAccount" + user1 + " ime.text"
Dim times As String
Dim timeread As New System.IO.StreamReader(timepath)
I have a textfile I need to open and I need to put each line into the array. What is the simplest way to add the elements/each line's data into the array while increasing the array as it reads each line? This is blowing my mind right now..I thought about using a counter and then redim-ing the array (while preserving of course).
I want to create a set amount of threads, and have those threads open the same file, and then each thread will go read a different line all the way down to the end of the file. Also I do not want to use thread pool, so I have to create the threads. I have the code to create threads, but I need help on the file part:
Try Dim s As New IO.StreamReader("C: est.txt") For i As Integer = 1 To 4 s.ReadLine()
[code]....
this only reads one line and proceeds with command.. how can i fix this to be able to read multiple lines, like read line 7, do command, read line 9, do command, etc..so much work to do and so many choices to choose from...
I am trying to create a textfile and write some lines into the textfile. However, the code that i am using can only write when the textfile is already created in the directory.
For this case, can i actually allow my script to search if a textfile is being created, if not create a textfile ???
Dim pathdir As String = "C:workingdir est.txt" If System.IO.File.Exists(pathdir) = True Then Dim objWriter As New StreamWriter(pathdir)
how to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
I have a tab delimited text file as so : name loan period loan amount John 5 years 6000 Sarah 5 years 6000 Jane 1 month 100
I'm looking to copy the lines where "loan period" = "5 years" to where "loan period" = "1 month", in order to show the comparison. The new lines would be appended at the end of the resulting file. The ultimate end result I hope to achieve is this : name loan period loan amount John 5 years 6000 Sarah 5 years 6000 Jane 1 month 100 John 1 month 100 Sarah 1 month 100
I've been toying about this with Visual Basic .Net, and so far, this is what I've come up with Dim strData As String Dim i As Short Dim strLine() As String lngSize = 0 FileOpen(1, txtloanlistinput.Text, OpenMode.Input) [Code] .....
I have two text files and each text file has various columns (each column is separated by a tab " "), now some of the fields in column1 text file2 match the fields in column1 text file1. What I'm trying to achieve is to remove every row in text file 1 where the field in column1 matches the field in column 1 textfile 2 - is this possible?I have used some basic coding in the past to remove certain lines, but nothing as complex as this.
Dim linesList As New List(Of String)(File.ReadAllLines("Path")) linesList.RemoveAt(1) File.WriteAllLines("Path", linesList.ToArray())
I use the following coding to replace a word in my textfile, would it be possible to add any coding that will remove all blank lines from the same text file? Dim EditMyFile As String = IO.Path.Combine("D:Test.txt") Dim inputFile = Regex.Replace(IO.File.ReadAllText(EditMyFile), "test", "test2") IO.File.WriteAllText(EditMyFile, inputFile)
I have tried the following but it doesnt work. Dim EditMyFile As String = IO.Path.Combine("D:Test.txt") Dim inputFile = Regex.Replace(IO.File.ReadAllText(EditMyFile), "test", "test2") IO.File.WriteAllText(EditMyFile, inputFile) Dim sText As String = File.ReadAllText("D:Test.txt") Dim sNewLines() As String = sText.Split(New Char() {ControlChars.Lf}, StringSplitOptions.RemoveEmptyEntries) File.WriteAllLines("D:Test.txt", sNewLines)
I'm writing a program that retrieves certain lines from a textfile. This textfile is rather large, so is it possible to have a progressbar that shows the progress when it retrieves?
I'm currently use visual basic 2008. The problem is I have try this code but,it produce no output. There is no problem with the code I guess. Here is my code
Dim i As Integer = 0 Dim line As String 'Dim reader As StreamReader = New StreamReader("C:\drill.txt")
I have a textfile which is in the following format.

There are only 5 rows and two columns. each field is seperated by a space (" ") What I'm trying to do is display column 2 value 1 in textbox1, column 2 value 2 in textbox2, column 2 value 3 in textbox3,column 2 value 4 in textbox4 and column 2 value 5 in textbox5.
below are a few lines from my text file(10929 lines)I need to read each line and insert into MS Access. each line is a column in my table and the record changes on every 8th line or to be more specific(on every 8th line you will see a number [1,2,3,4,5,6,7,8,9.....] this is where another record starts,
I want read the content of the text file and write to vb.net application. My text file name is wires.txt. The above code only read and the file appear on the application. I dont want the file to be visible to the end user.
I'm trying to place the contents of a text file (just a list of names) into a list box when the form loads.
My code currently looks like this:
Imports System.IO Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code].....
I can get the names into the list box, but they're all on one line. I thought about using a For...Next loop to read the contents of the text file, but I got into all sorts of trouble; do I need an array with that method? So I've got back to the code I originally had.
I have a form with 2 listboxes. I've added items in each listbox. I save all the items from each listbox to a text file. What I want to do is open the text file and I want each string inside the text file to go to the appropriate listbox. How can I make my program recognize where each string belongs?
I have my code it is able to read a text file and do checks each line if there are 7W and 5L in that particular line, if no matches it will remove that line... 1 problem i face now is that, there are duplicates in my textfile..Im not sure how am i going to remove the duplicate in the text file. I want to know if there is a way to integrate an additional function inside my code to check if that particular line is a duplicate so i can accomplish 2 tasks at 1 time... Since there are about close to 1million records in my text file.
What I am trying to do may be better for use with SQL Server but I have seen many applications in the past that simply work on text files and I am wanting to try to imitate the same behaviour that those applications follow. I have a list of URL's in a text file. This is simple enough to open and read line by line, but how can I store additional data from the file and query the data?
E.g. Text File: link1 - 0 link2 - 0 link3 - 1 link4 - 0 link5 - 1
Then I will read the data with: Private Sub ButtonX2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonX2.Click OpenFileDialog1.Filter = "*txt Text Files|*.txt" If OpenFileDialog1.ShowDialog() = DialogResult.OK Then Dim AllText As String = My.Computer.FileSystem.ReadAllText(OpenFileDialog1.FileName) Dim Lines() = Split(AllText, vbCrLf) [Code] ..... Am I going completely the wrong way about storing the data after importing from a text file?
This is my first time using a list vs an array but I'm having a bit of trouble. I am trying to read a textfile into a list of song objects. I am reading the file successfully into the list however after the loop ends the program stops executing the load event and ignores the populateListBox() procedure. Any thoughts.
how do i have my app read a line from a textfile and if that line equals "whatever" proceed with command, this case a msgbox.so much work to do and so many choices to choose from...
I've got a csv text file "test.txt" in the following format with one record per line in the following format: Builder,Bob,B,99HappyStreet,Springtime,4
I've read them into an array and in design use the first two to populate a listbox and then use a selected index to fill text boxes and some list boxes.
How do I write the changes made in the text fields back to the position in the file where it was? It has me stumped although I'm sure there is a SelectedIndex option that can work.
I've considered having all the new/changed data saved as a new record and then just deleting the 'old' entry but my delete code gives me a selectedindex-1 index out of range exception error that I'm working on as well. I am sure both problems are related.[cod]e...
