VS 2010 Deleting Lines From Text File?

Dec 16, 2011

I have the following code to read a csv file and copy each line to another file as long as it does not contain certain strings, it seems to work a little but it leaves some lines in it shouldn't, and it's also taking lines out it shouldn't as if I keep running it again on each output file it eventually takes everything out!

Private Sub Strip_File()
Microsoft.VisualBasic.FileOpen(1, tFile.Text, OpenMode.Input, OpenAccess.Read)
Microsoft.VisualBasic.FileOpen(2, "C:AcmeIPPMaster.csv", OpenMode.Append, OpenAccess.ReadWrite)

Deleting Duplicate Lines In A Text File Using An Array

Sep 27, 2009

I am adding line entries in a .ini file. The problem is, I am creating duplicate lines in the file, which I do not want to do. I searched this issue online, and the consensus is to use an array, loop through for duplicates and create a new file. However, being so new at this and teaching myself how to code no less, I am at a dead end. This is not a school project, it is something I am doing for work on my own time. I have all of my code done for the program except for this last step.

VS 2008 Deleting Multiple Lines In A Text File?

Sep 20, 2009

I need to be able to search through a text file and find a line of text, then delete that line and the 7 previous lines and also the line following the searched line. Basically the program creates student records to a text file and asks if the user wants to mark the record for deletion then when the user exits the program, I want it to find the records mark for deletion and delete them.The records in the text file look like this:

Name: Some, Students, Name
Age: 20
Phone Number: (555) 555-5555

File I/O And Registry :: Deleting Lines In A Sequential Text File?

Mar 22, 2009

I know that Deleting a specific line in a sequential text file is impossible but instead copy the needed lines and not copying the unneeded ones to an output file .. killing the old one and renaming the new one with the same.. I can't make this step...

That is my record file

Code:
Input #1, CustomerName, CustomerHomeAddress, CustomerBussAddress, CustomerTel1, CustomerMob1, CustomerID, DateRent, CarRegPin

Code:
"Josek Sam","68 West Land Street","149 Union of States","4524563","45635463","JOSKSAM1",#2009-03-02#,"MILANCGLZ2008"
"Josef Malm","142 Unions Street","64 Hamersters Street","452504","42542054","JOSFMALM2",#2009-03-06#,"MILANCGLZ2008"
"Dave Green","131 Oxford Street","96 BlueBane Route","452542452","43254345","DAVGRN3",#2009-03-07#,"MILANCGLZ2008"

I made a form that when you put your CustomerID in Text3 Box.. it access the records and make some calculations. now.. The customer will return the car.. Then his data should be deleted.. I want to know how to make that when I enter the CustomerID and press on the Command button .. It copies the other lines to a new output folder and doesn't copy these ... So it appears to be deleted using this way..

Get A Bunch Of Lines From A Text File (they Will Be Filenames Eventually) Which Are Split By New Lines And Puts Each One Into An Array?

Jun 22, 2010

I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..

Dim ary() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then

[code]....

The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

Read Lines From Text File 1 And Delete Those Lines From Text File 2?

Sep 15, 2009

I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

Deleting A Text Line In Windows Forms Project

Jan 10, 2011

I am busy with a project converting VS2005/2008 sln files.

I am quite far but have came acroos a problem with my source code.

I have found the files I need to change, I have changed them to the version that I need.

I now need to read the files back into my program and delete the line I have changed as it contains project numbers that are irrelevant. Then I need to save it.

I have got as far where I have searched for lines that begin with 'Project'. I have changed this also so it's now a question of reading the files in, Deleting the line with the 'Project' number and saving them.

Forms :: Resolved ClassicXP/win98 Style GUI On Vista?

Jan 26, 2010

my application has "picked up" the old style button design. In Vista the buttons have a slight shadow / 3d effect, however, my application appears not be using the default style and instead applying the older XP, Win98 typ appearance. At first it didnt bother me, however, not its annoying and rather than rip all my code out and apply it to a new project, i would prefer to remove the offending code call.

Its a long shot, but i thought i would see if anyone here knew what might be causing it?

Forms :: Resolved Search And Display ArrayList Stored In A Hashtable?

Mar 25, 2009

I am new to VB.net and I am trying to work out an exercise from a book I am reading on VB. Basically I am storing some book information in a hashtable using a class called Book to store the book information. I am trying to work out my Search and Display All procedures. My Search will work for the first value in my arraylist but not for any other values. I even added the ISBN to my book class to try and use this as a search point. The ISBN is used to pull the item from the hashtable as well.

In the main code I am having problems with the ButtonSearch and ButtonAll.
