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]

View 4 RepliesAfter 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("|")

for example I have this plain text:
Quote:

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?

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 want to take a comma delimited text file and then select all unique records based on one of the fields in the text file. should i read the text file into a data table or just use a data reader?
View 7 RepliesSo i'm new to working with vba in access and i'm having trouble getting this code to work. What it is suppose to do is take a selected text file and read the original file into a list box. Then there is a second button that when pressed will convert the text file from a pipe delimited file into a tab delimited file and then show the changed file into a new listbox.
Option Compare Database
Option Explicit
Function GetFilenameFromPath(ByVal strPath As String) As String

this is how i would normally import a comma delimited text file into a ms access table:
sql.CommandText = "SELECT * INTO [tblMailList] FROM [Text;DATABASE=" & System.IO.Path.GetDirectoryName(Me.OpenFileDialog1.FileName) & ";HDR=NO].[" & Me.OpenFileDialog1.SafeFileName & "]"
sql.ExecuteNonQuery()
my question is, how can i do something similar for a tab delimited text file?
After two days of looking I give up. The basic problem is that at the end of my program I need to be able to write out a text file and then read that same text file back in when the program restarts or reopens. The best and easiest way I have found to read in the file is to place the text file with in the Resources and use this code.
Dim ReadingIN As String = My.Resources.Mytext
So then I want to be able to change that string and then write it back out. Part of the problem is I want to be able to use this from a flash drive or a changing directory.
I have tried but it doesn't work
Dim WritingOut As String = ReadingIN + "Edited text"
Dim DirString As String = My.Resources.Mytext
If System.IO.File.Exists(TemperString) = True Then

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:
ID Name
1 Patient
2 Bed
3 PatientSet

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
text = x(J).Split(vbTab)
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 am trying to import a TAB (NOt comma) delimited text file into a DataGridView. The following code works fine if I have a comma separated file. All I have to do is change the FMT to "Delimited".It just does not work with FMT=TabDelimited. All columns are read into single datatable column. The text file is ANSI text and I have double checked to make sure Tabs are tabs and not spaces, even exported a sample Tab Delimited file from Excel.Can this even be done using Text Driver? [code]

I'm having trouble with reading a file from embedded resources.
I'm starting to learn about developing applications for eBay. You can pass queries to eBay in XML format, and receive replies back in the same format.
I have some examples of code to do this. Here's how the sample code loads an xml file, containing the query.
'Get XML Document from Embedded Resources
Dim xmlDoc As New XmlDocument()
Dim current_assembly As Assembly

I can't see any difference between the sample and my attempt.
The Assembly Name and Root Namespace in my project are both set to "Sample," just as in the original.
I've tried things like changing the filename and the namespace, but I still can't get it to work.

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?

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.
View 3 RepliesI have a text file with for example this data in it :

I used " , " to delimit individual pieces of data and " " to denote end of line.I'd like to be able to split the files into lines and assign each line to an array then split each of those array strings into the comma " , " delimited data and feed each piece of data into another array ready for writing to a datagridview.

I am new to the VB Forums. I searched the forums for an answer, but could not find one that exactly fit my issue. I apologize if I missed it. What I am doing is I'm pulling strings of text from a backslash-delimited text file and throwing it into a (Of String, Array) dictionary. This info is then displayed, added to, removed from, through the use of the form. Changes to the entries (new, old, or otherwise) then need to be written back in the same delimited format to the text file.

I would like to be able to perform SQL queries on these files. How can I connect to a text tab delimited file to either pretend it is a database table or import it into SQL as a table, preferably through VB.NET? I could have 300,000 rows, and the fields are all numbers, not text... I have manually imported these files into SQL before using management studio, so I know it is possible but I would love to be able to do it programmatically.
Is there any way I can get the SQL code from this process because it does exactly what I need it to do but it is manual. There is an SSIS package that I saved, but I do not know what that is.
