I have a text file with ";" as a delimter but I am not able to seperate the text, I am able to read one line at a time using ReadLine Function but I can not find a way to separate columns from this line.
After some thinking, I think I figured out how to read delimited text. I was just curious as to whether it'd be better to use StreamReader.ReadLine or File.ReadAllLine or if it matters at all? I'm assuming the ReadLine method would be better if I'm working with a larger file since ReadAllLine would store the entire thing in memory? Here's my code - I'm reading from a text file and displaying into a listview.
File.ReadAllLines Dim lines() As String Dim parts() As String lines = File.ReadAllLines("C:lah.txt") For Each line As String In lines parts = line.Split("|") [Code] .....
I'm having a problem where instead of reading a text file from the location string, I changed it to read the text file from the resource location and it breaks my program. I've also used the insert snippet method to get most of this code, so it is safe to say I don't know what is going on. [code]
I was trying to read Quote-delimited file using VB TextFieldParser. It doesn't work. However it seems to work if I set the delimiter as comma (","). How do I read quote delimited file?

I have been struggling to get vbscript working for last three days of relentless effort. I have windows 7 ultimate and upgraded from windows vista. searched the web for solutions and tried out all the options I think I have, but yet no luck.
I tried registering vbscript.dll and I get a succeeded message back. Everything seems to be fine. but, I just cannot run vbscript on my computer. It complains that "can't find script engine vbscript for script ....". I have a hunch that it is something to do with "microsfot security essentials (my virus protection software)" or with UAC.
When I use to do some Delphi programming you were able to define variable as a target for a comma delimited file and then under that give variable names for each field to fall into. I forget the syntax now but it looked something like this...
Using Getline as Record: RecordId = Integer RecordName = String RecordAddress = String;
I have the following text file (ExamMarks.txt) John, 85, 95, 90 Micheal, 60, 75, 75
I want to extract a line and take the Name and separately and the ints separately. Then I want to print the name and the average of the numbers like this in a label: John's average is 90 Micheal's average is 70
So far I can only display what is in the text file in a label (see below):Dim FILE_NAME As String = "C:ExamMarks.txt"Dim TextLine As String If System.IO.File.Exists(FILE_NAME) = True Then
I need to be able to select a title from a listbox (lstBooks) and I need the data from a comma delimited text file (books.txt) to flow into a form (frmDetails)when I click the UpdateToolStripMenu button. Program is attached.

I need to be able to read common delimited text that the user enters into a text box. For example the text box would look like this:1,200,02,200,04,120,1203,200,120I need to be able to read the lines and put the data into a multi-dimension array with all the first values in column 1, all the second values in column 2, and all the thrid values in column 3.
I have used Mid,InStr and other methods to get a substring of a string from one text file and copied the required string to another text file. While I get the correct string, vbscript however generates a BLANK SPACE after evry character in the output string.
I tried to use the Replace function inorder to replace the " " with ""... but the function does not detect any blank spaces at all to replace.
Instead of copying to another file, I even tried to replace the undesired part of the string with a " " and get only the required part ... but then again it gives the same problem[ a BLANK SPACE after evry character]
I'm trying to parse a text file. First I plan on extrcating each line, then extracting each field by searching for a tasb.When I use InStr to search for a (return for end of line) or (for tab) I always get a zero. But if I put in a visable letter such as a I got a 5.also I tried /r, /n and all return a zero.The file looks as follows:
I have been able to load a drop down meny with a file, but the file is comma delimited. I tried to use the split function to only read the first part of the file before the comma, but I'm getting an erroHere's what I'm doing:
Dim Arts As New IO.StreamReader(System.AppDomain.CurrentDomain.BaseDirectory & _ "Artist.txt") Do Until Arts.EndOfStream
I've got a problem reading in a Tab-Delimited text file. There's an extra tab in one of the fields its reading it thats not a delimiter, and it's throwing off me reading the file into a table. This specific file does have quotations around that field though.
What would be the best way to take that tab out before splitting the row by vbTab?
Im reading each line in the text field like this, splitting on vbTab. X is a string array
This is my first program that I'm trying to write. I have been trying to make an application to run a date filtered query against a SQL server and output the results into a txt file that I define. I believe that my code is close for getting the data. I cannot figure out how to actually write the data into a text file. I am trying to use the datareader and streamwriter, but I am not sure what to put in the streamwriter.Write() function to actually get it to past the lines in the text file.
I previously asked a question about my meeting planner app, and how to delete a specific entry in the array. Someone had the interesting suggestion of using a ArrayList, instead of a normal array. I am attempting to learn ArrayList, but to no good result. I can't even get the ToString method to work correctly to write what I want it to into a text file.[code]...
My plan is to have each of those three fields to have their own entry in the ArrayList, but when it is saved to text file, those three fields are comma delimited to a line for each appointment. Of course when the text is loaded, it will have to be converted back. Can anyone point me in the right direction or have any other method of going about this with the ArrayList?
I am having some trouble including tab and space delimiters in my multiple delimiter code (see code below). It seems I can not just add the <vbtab> and <vbCrLf> codes into my delimiters list so I tried to replace them beforehand with a Clean String Function (also see code below) but it didn't seem to work. Ultimately, I would like to add any delimited text file to my datagridview.
The code below is working fine except for tabs and spaces (including next-to-each-other separators) I am using Visual Basics Express 2008.[code...]
I've got a problem in Importing Text delimited File to access Db , I always get an error "No value given for one or more required parameters'while execution [Select Into] Statement
[LEFT] Dim svdialog As New SaveFileDialog svdialog.Filter = "Access Database Files (*.mdb)/*.mdb" If svdialog.ShowDialog = Windows.Forms.DialogResult.Cancel Then Exit Function
what would be the easiest way to open a comma delimited text file - each field is surrounded by quotes - and then analyze this file to find the record with the most fields being used? right now i bring the file into and access db then loop through each record to see if there is any data.
Is there a set function in vb.net that allows you to read a delimited file with text qualifiers? In the past I have used the split command but that does not allow you to take into account the text qualifiers.
I am trying to open a text delimited database using the jet.OLEDB.4.0 driver. My connection string is as shown here: Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & dataDir & "; Extended Properties=""text;FMT=Delimited( )"";"
I have read that you either need to alter the registry, or to add a schema.ini file containing information about the delimiter in order to recognize the delimiter. My question is if there is any way to do this without altering the registry or adding a schema.ini file, as both of these are unfortunately not an option. The only solution I currently see is to split each row, is this the only way out.
i'm currently a student in a local polytechnic school, i was tasked to create a program that consisted in 3 parts which will bind together once it is done.at the moment, i have done the first part which is embedding video player into VB.now for the second part is that i'm stuck with, i need my VB to "read a text file which is space delimited and write into a access database" now my program is stuck at this and i do not know how to continue. i have been looking at alot of website for guide and codes but non are working.
