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...
what i need to do is open a txt file, read line by line, decode each line into an array and display. Now all works ok apart from one line.
sTextLine = objReader.ReadLine() <-- Value of string cannot be converted.
full code here ------------- Dim objReader As New System.IO.StreamReader(sOpenFile.Text) Dim sTextLine As New ArrayList() Dim sText As String = "" Dim i As Integer = 0
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:
I'm trying to read a file line by line into an array but It skips the item at index:3 I have it msgboxing just to make sure and it wont even touch it.
Dim Btn As Button = DirectCast(sender, Button) Dim path As String = Application.StartupPath & "Libraries" & Btn.Text.Replace(" ", "_") & ".ipt" Dim i As Integer = 0 Dim lines As String() = IO.File.ReadAllLines(path)

I'm making a program which has 7 textboxes. I intend the program to be used for classes in school, so the text would be like 2D Art, Geology etc... whatever your classes are. I have figured out how to use the streamwriter to take the text in the textboxes and write them to a .txt file however, my issue is with loading the text from the .txt file back into the textboxes. I did figure out how to write it so that all the text in the .txt file is loaded back into textbox1 but I have 7 textboxes... Here's the coding for the Load button:
Private Sub Button46_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button46.Click Dim MainWindowLog As String = "V:Users(O.o)~(--_--)~(o.O)DocumentsVisual Studio
Dim sFileName As String Dim srFileReader As System.IO.StreamReader Dim sInputLine As String sFileName = "D:UsersArbenDesktopSerieA.txt" srFileReader = System.IO.File.OpenText(sFileName)
[Code]...
under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file
I have a textfile wich my app will have to read.The textfile will be like this
Hello=Bye SeeYou=SeeYa GoodMorning=GoodAfternoon
And so on, each line in the textfile will consist of two words seperated by a = Now I want to load this textfile and then be able to use each line and have a name for the word on either side of the = and then do something with line 1 word 1 and then do something with line 1 word 2 (word 1 beeing the first word before the = and two beeing the one after the =)
I'm making a function that is supposed to delete a line from a textfile "test.txt". I'm having no problems with finding what line i want to delete. The basic idea is this: read the whole file with streamreaderdelete the linerewrite the file with streamwriter. My problem is the last, how can i completely remove the file content, and write another string in it, writer.writeline just appends a line.
I am having trouble removing a line from a text file. When I click on the button in order to remove the line it gives me an error that access to the file is not possible. Now I assume that the file is in use during me wanting to change it and therefore cant save it while it is loaded in ht application. I have tried a few things but cant seem to get it to work.Essentially what it does is that I have another dialog that a used can add data, the data is then written to the file FilingLocations.txt and then it saves it and loads it again. But once the line is no longer needed I would like to have the option to remove the line agaise.
Here is the code: Private Sub cmdRemoveLocation_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdRemoveLocation.Click
I have a textfile which is in the following format.
[code]...
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.
I have a program that reads a text file tab delimted using OLEDb I need to be able to allow the user to insert a user created record into the file which I can do. The problem is I need to be able to let the user edit that record. From my understanding you can not edit or delete with OLEDB only insert So I thought I would read the file using stream reader, find the line I want to edit and just delete it, rewrite the file, then let the user insert a new record?
Dim strDelimiter As String = vbTab OpenFileDialog1.InitialDirectory = "C:\" OpenFileDialog1.Filter = "Text Files (*.txt)|*.txt"
I have a program that searches for a word in a .txt file. When it finds the word I want to print the following 5 lines under that word. So for example: I search for "juice", and my label grabs this out of the textfile: juice apple grape orange milk Is there anyway to this in VB.NET?
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 have not had much time to go threw my code properly as this is some urgency. I need to remove line 1 from a textfile if it contains a string but its not working.I have 500 files and not going to do this manually.
Code: Private Sub btnRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRemove.Click If String.IsNullOrEmpty(txtDirectory.Text) Then OpenFolderDialogDirectory()
[code]....
I also feel the function is very pointless sime i am opening the file twice.
How do I read a line from a database using WHERE? I've read this post but it doesn't really cover it and the forum search throws out the words, 'From' and 'Where' as being common. This is my bit of code but it just skips over it as if it doesn't exist so presumably there's an error, I dunno. I'm trying to read an entire line from the database where it equals the value of 'getweek' where 'getweek' is a variable.
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.
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.
