I'm using text files as an array to store and remove information, however I do not know know how to adapt this code so the line I search for is removed.
My text files are set up as such:
021,Donovan,56 Eynesford Crescent,Bexleyheath,CT5 1TR,09/08/1967,13 March 2012,Bronze
062,Fredrikson,6 Freil Road,Gravesend,CT9 1RB,12/06/1995,13 March 2012,Silver
So I can search and locate the ID, in these cases 021 or 062, but I want to be able to remove the line I want, once it's been found.
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

After I add tons of text lines on RichTextBox, I need to select any line(s) by just clicking this line. After that this line is highlighted. Then I click one button to remove this line. How to do that? (the starting character for each line is the same)

I have 2 things that i need to keep in sync An array of file paths A listbox with just the file names of the file paths The indexes of each correspond with the other object.If the user deletes an item from the listbox (the file name) i want to delete the item in the File Path array. Once this is done, i want the file paths and file names to still be corresponding?
How can i remove an array item by selecting an item from listobx and press remove/delete button?for an example, if i want remove index 2 from listbox, so the array should remove index 2 item and move the item of index 3 to index 2 and so on.

I must use streamreader to read text file line by line into array.
Here's what I've got.

Row3 ;W910 RF350022 ;Increase backlight by 100% ;(c) spring ;(p) spaceman +1000000 F5 000000 5555 44 555555 904938291 8676859 00
Row4 (Duplicate of Row3) ;W910 RF350022 ;Increase backlight by 100% ;(c) spring ;(p) spaceman +1000000 F5 000000 5555 44 555555 904938291 8676859 00
if label1 = RF350022 label2 = Increase label3 = spring label4 = 100%

In the following code, the items master is displayed the user can select as many as needed to add to the budget grid. Now the need is to remove a line that was added if so desired or if by mistake they added the wrong line.[code]..
I have a text document that has a lot of data. I want to search for a specified term say "apple" and remove that entire line of data from the document.
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'm having a little trouble deleting multiple lines for a listbox. I know how to remove a single line, which is this: [code]If I change the value for IndexOf to SelectedItems, I get an error stating that -1 is not valid for index.I am guessing this needs to be done using an integer array and a for each but I don't know how to do that. I really never bothered to look much into arrays.
How can you remove a specific line from a listbox? How can you like make it so instead of password it would show ******* but on a listbox because it doesnt have passwordchar option. and how can you make it save the listbox data in the my.settings
