i know i have to use a loop to get each line of the textbox onto a newline of a textfile but i dont know how to figure out how many lines of text the user has entered into a textbox. I tryed using a try statment to loop until it errors, it seems to work sometimes but other times it only takes half of the textbox and adds it to the textfile. And if atmaweapon reads this, i tryed to make better names for variables. Here is my code,
Code: Path = ("Meals" & ComboBox1.SelectedItem & "" & TextBox1.Text & ".txt") File = New System.IO.StreamWriter(Path) If ComboBox2.SelectedItem = "1" Then
[Code]....
how many line of text there are... im not so shure how good it is to run a loop tell it errors for a textfile, but its the only way i could think of.
The code below allows me to write a single line to a textfile. Id like to be able to open an entire textfile into a textbox, be able to edit said text and have it automatically write back to the same textfile.
Private myCoolFile As String = "C:UserskevinMy Documentspasswords.txt" '// your file. Private myCoolFileLines() As String = Nothing '// String Array to read File Lines into. Private sTemp As String = Nothing '// temp String to be used as needed.
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
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 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'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")
Basically what I want to achieve with this code is to read the text file and import the corresponding line to its textbox. But when i run this code BUT_A.text returns the value that is set for BUT_B on the textfile then any code after that doesn't import at all. Here's the code I am using for the open button (I'll be adding a OFD later)

I'm working on a new project and i need the program to pick one of the lines from textbox1 on a ramdom way: I have 1 timer and i want something like when the timer "ticks" to pick a different line from the textbox ex:
I have strMyString that contains about 5000 lines of data. There are some lines of data that need removing if they contain a certain string, such as "http", "www.", ".com", "cat", "fish", etc. The whole line needs removing. Each line is separated by a vbNewLine or similar.
How can I do that? Does it need pasting into a rich textbox first before processing?

I'm trying to integrate a parental controls feature on my webbrowser. Now, the user creates a text file containing a list of the words they don't want their child searching. Here's an example of what would happen. The list looks like this (I wont use vulgar words):
dog cat baby fish tree
and the kid tries going to "treeandbabynectar.com". I want a messagebox to come up saying "Site blocked". I want it to be able to detect the tree and baby in treeandbabynectar and realize the text file contains the word tree and baby and block the site. Is this possible? How would I do this?

I have a textbox which has a numeric value that changes - would it be possible to check if that value matches two numeric values in a text file? and if the value matches then to display some text in a label? The textfile only has fields displayed like so Horizontal 55 Vertical 16 So I would only need to check if the numeric field in textbox matches the two numbers in the second column. In the past I have use System.IO.File to create/delete/append to files but I havent come across anything like contains.
just another little problem here! Trying to write a quiz for a college portfolio and having trouble with writing to a .txt textfile. On one form(form4.vb), I have a listbox that picks up the information held within a notepad textfile called "usernames" which contains names of quiz users. When written in manually to this textfile, my listbox picks it up fine, however, on a different form(form3.vb), I have a textbox where a user inputs their name, this is supposed to go to the "usernames.txt" textfile to be picked up by the listbox on the other form but instead, it does not write anything at all and if there is already text on this textfile, it wipes it all out.I also have to use the application.startup path instead of the usual C:my documentents etc so i would have to begin with something like this: (Note: code is a little mixed up due to messing around with different variations but this is just a example)
