Load A Text File Into A List Box Using A Delimiter?
Jul 20, 2009
Alright, im trying to load a text file into a list box using a delimiter(sp?)I have 2 list box's lstFirstName and LstLastName I have the code to load it into a list box
r = New IO.StreamReader("c:\test.txt")
While (r.Peek() > -1)
lstFirstName.Items.Add(r.ReadLine)
End While
r.Close()
And at the moment this will just load the whole list box, how can I use a delimiter to split it up?So John Doe in the text pad will show up as lstFirstName: John lstLastName: Doe Sorry if im not all that clear, if you dont understand I will try to explain it clearer.

I'm trying to use VB.NET to parse a very large plain text file (2 GB). It is a database and has a field delimiter of SOH and a record delimiter of STX. I want to separate the fields and records of the file.
I would normally read each line of a text file and then use the split function to separate out the fields. I can't use this approach as there isn't always a delimiter on every line.
Is there any way to read a file until STX is found (rather than one line at a time)?

I am wanting to write an application which opens a delimited text file (either comma, pipe, colon, semi colon) and displays the file on the form. The same feature is in Excel when you import a data file. After selecting the file it shows the contents and you can choose the delimiter. Once the delimiter is chosen the data shown reflects this and updates to show the correctly formatted data.

I'm trying to Load data from a Text file, which is "," Delimited into 6 List Boxes.. Want a FileOpenDialog Box so that the user Can chose which Office Id txt File they wont to load into the List Boxes.How it works is;
-The user Enters an Office ID (e.g HH33)
-The user fills out the rest of the program, the data is then generated into the 6 list Boxes
-User then clicks Save to File button.
-The program creates a Text file with the name coming from the Office Id, so if the user enters HH33, the text file is created with name HH33.txt.
-All Data entered by the user under the office name HH33 will be added to the Text File..[code]

How can I change the delimiter when writing my Access table to a text file? I was hoping it would be as easy as adding a similar option like we do for HDR=No; maybe Delimiter=|
Dim AccessConn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|mydatabase.mdb")
AccessConn.Open()Dim AccessCommand As New System.Data.OleDb.OleDbCommand("SELECT * INTO[Text;HDR=No;DATABASE=" & userPath & "].[" & fileName & "] FROM tblMyTable", AccessConn)
AccessCommand.ExecuteNonQuery()
AccessConn.Close()

Here is the code for my program. We are making a membership list and it needs to load with just the names in the txt file that is in the debug bin. The txt file is set up in one column and holds the member name and the next line is member number and so on. Information is read into an "array of structures" and the display is supposed to be ONLY the names in the listbox on load. This is my problem. I had it displaying all th txt file info and I just need the names. I tried what you will see in the code but it is not working and my book is less then helpful when it comes to examples and/or knowledge on the subject. Though it could be too many hours spent trying to get it to work.
Imports System.IO
Public Class frmMemberList
Structure Members
Dim member As String
Dim number As Integer
End Structure

I need to load a large txt file that is in a fixed width format. There are over 45K lines, so speed is important.I need to load one of the fields into a dropdown box and have another field (label) display the text of another field in the related line.I could import the file to an access db if needed, but would rather not as i also want the txt file to update from a link on a regular bases. So having it in a DB would be more work to process that part.[code]

I've been working on this program all week and I've been able to finally get it to work except for one problem. The program is suppose to parse strings from a text box to a list box and then from a list box to a text box using the users choice of delimiters. I can't seem to figure out how to get the last comma off the end of the list. ie cat,dog,elf,It seems it should be easy, but since I've worked on this program so long I believe I can't see the forest for the trees. I don't want for you to do my work for me.

I want to read a text file with unlike delimters into a collection.This is what the file looks like:
_Item 4916 0.00 781.21
_Item 2831 0.02 842.25
there are 10029 items and i am trying to get each items description into 3 different collections: Item "names" (first column), Item "weights"(second column), and Item "values"(third column).the delimiters are as follows:
______(3 spaces)____(1 space)____
considering the amount of items in the file, it would be a complete waste of time to edit it.

I've made a rudimentary program that combines multiple files into one single file. Currently if I combine two .csv files together the output comes out correctly for what I need, which is a coma delimited file. When I try to combine two .csv files into a .xls file it doesn't format correctly (I get all the data separated by commas, but thrown into one column in the .xls file). For this reason I believe I need to add a delimiter.I'll post my code below.

Before I begin I would like to mention that I am not a noob in VB, it's just I've never had to do anything this complex before. Basically what I want is to have a program that you can load a txt file in, have it copy key words, and paste it in a textbox so I can use it later on. So in this text file, there is a bunch of info, but I am only needing a certain part. Here is an example of a text file (actually a .dat file, but is easily read):

I want to load a csv file (A comma delimited text file) into a datatable. I found the OdbcDataAdapter Class which looks perfect, but it says it is supported only in version 1.1 of the .NET Framework.
Is there a better way to import a csv file into a datatable? the first line has the column headers.
I am using Visual Studio 2008, using version 3.5 of the .NET framework

I've been staring at my code for a few hours, and cannot think of the next part.For my final I need to make a hangman program Pretty much I have a button to load a .txt, a label, a multiline textbox(which will be hidden later), and a normal textbox. I need the program to load the txt file, and randomly select a word. Then have the program put a " - " for every letter in that word The program loads the txt file,to the multiline textbox,but I don't know what to put next. EDIT:After looking at my book i noticed it shows how to make a hangman program, but without loading a text file. So, all I need is the code that will make it select a word randomly from the list, and i think I can do the rest..
