Removing Line Number Textfile Only If String Is At The Top?

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.

Removing Duplicate Rows In A Textfile Then Add To Datatable?

Aug 16, 2010

I am reading a textfile and extracting information from each line. For example string1 and string2. I am then writing these string to a datatable.

However, sometimes there will be repeats in string1 and string2.

If there are repeated lines I would like to be able to delete the repeating line and add a counter to find the total number of repeating lines.

so if a string repeates 3 times I would like there to be a column with a 3 displayed next to the line in my datatable.

File I/O And Registry :: Line By Line TextFile Reading?

Mar 5, 2009

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

VS 2010 Value Of A Textbox Matches The First Value Of Each Line In A Textfile?

May 30, 2012

I have some coding which displays a label if the value of a textbox matches the first value of each line in a textfile.

Dim sList As New List(Of String)(IO.File.ReadAllLines("Path"))
Dim i As Integer
For i = 0 To sList.Count - 1

[Code]...

The problem is if the textbox has 1 and the textfile has 11 it will display the label, what would be the best way around this?

I have tried sList(i).Contains etc but none of them are doing the job.

VS 2010 Removing Line From Either String Or Textbox

Aug 3, 2011

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 have a program remove lines from a text file if they start with a certain string. I haven't had much luck with this over the past couple of days so I thought I'd try and get some advice.

Dim SourcePath As String = "C: est.txt"
Dim fileLines As List(Of String)
fileLines = New List(Of String)(File.ReadAllLines(SourcePath))

I am reading a list of IP's from a text file. After every procedure, the first IP (the first line) needs to be removed, and the new first IP will be read at the beginning of the next procedure.

VS 2010 Removing A Line Form A Text File?

Feb 8, 2012

I'm trying to remove a line from a text file that begins with a set value.

The idea would be to paste values into a Windows form, which then finds each line that begins with that value (a 5 digit number) and removes those lines from the file, and then removes the gaps.
