VS 2008 : Load A Comma Delimited Text File Into An Array?
Dec 19, 2010
I have a text file, with several lines of comma delimited data. The easy part is that each item fits into the same field, so I can use a 2 dimensional array. I would like to use .net classes to do this, not the old file handling functions I was used to.How can I take the text file and load the data in the text file into a 2 dimensional array.Here is example data in test.txt
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
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.
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?
I want to add the contents of a comma delimited text file(PracInfo.txt) into a Dictionary on Form_Load. The contents of the file are as follows: wlvc,coadmin mrmd,thadmin ccoa,oaadmin bfhl,bfadmin trty,tradmin nppp,npadmin
For example, I want the wlvc to be the key and the coadmin to be the corresponding value. The code I have so far goes as follows: Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim sr As New StreamReader("C:Programming filesPracInfo.txt") Dim openWith As New Dictionary(Of String, String) Do While sr.Peek <> -1 strHold = sr.ReadLine() ' here I would like to use the String.Split method on strHold and then put that into the Dictionary using Dictionary.Add(Key,Value) but not sure how to do this???? Loop End Sub End Class
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 have a text file with for example this data in it :
"19 Mar 2010","6:00","16:00","10","1","9","6.61","59.49" "20 Mar 2010","9:45","19:15","10","1","9","6.61","69.89" "21 Mar 2010","9:00","17:00","8","1","8","6.61","99.32"
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've spent a while trying to get Split() to work but I get errors regarding converting strings to one-dimensional arrays Also the Split() method asks for a "ParamArray" but I haven't been able to find examples of other people providing them on the net any idea what those are about?
i have a stream reader reading a csv comma delimited file, its skipping every second line though if i edit the file and enter blank lines in between, it reads them correctly
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'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]
I'm attempting to read from a comma delimited file, the values are put into a structure (employeerecords) i want to know how i can access the separate sections of this structure i will provide my code so far, i apologize for the comments I'm making sure i know whats going on, I'm new to this, the code currently just dumps the whole file into a textbox, i would like to be able to access and manipulate the individual fields but i am at a genuine loss.[code]
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 recently asked a question about reading a file with Streamreader to variables arrays, but I made it more complicated than need be. Here is the simple version of what I am trying to do:
dim MyNumber(1) as String
strMyFile = 100,200 (I already have this)This is the result that I am trying to make happen:
MyNumber(0)=100 MyNumber(1) =200
I would also like the result to be MyNumber(0), MyNumber(1) as double, but I could do that in a later step. This is almost embarrassing to ask, because it is probably basic stuff.
I used to just code up a module that looked like this Ref to MS Access 11.0 Obj Lib was set
Dim myaccess as New Access.Application myAccess = CreateObject("Access.Application") myAccess.Visible = false myAccess.OpenCurrentDatabase("c:\path\databaseName.mdb")
But now it seems that even with that ref included, none of these commands exist. From what I've been reading online, to do this via .net, you have to parse the file out and create a serious of SQL inserts. I'm assuming/hoping/praying that there is a more efficient way to do this...
What is the best method to parse through a Comma Delimited .dat file? I am using VS2002 and VB. My code will be looking for certain placeholders within the files and pulling the value from that element to populate a table in SQL2000.Here is a sample of one row that is in the database so far:17768 01 1770 003 2009-11-01 00:00:00 5065.14 NULL NULLEach spaced section is taken from a part of the .dat file, but being manually keyed in for now. My job is to automate the reading of the file, and writing it to the SQL database.Here is a sample of the flat file I am trying to parse:
I am looking for a different kind of solution here. I have a database in which I have around 14 tables. I have to write the output of 14 seperate queries to each of these tables in to a comma delimited file. I know how to write it using direct read , loop through and write to text. What I am looking for is a more configurable solution. I should be able to configure my application if a new table/query needs to be outputed. I should also be able to configure the delimiter to use.(I am Ok with C# or VB.NET )
are loaded in listbox1 and i split the "," and its value to textbox1 when i select the index 1 in listbox i get the same value as first index here is my code for load the textfile to listbox
Dim linereader As New System.IO.StreamReader(OpenFileDialog.FileName) While (linereader.Peek <> -1) ListBox1.Items.Add(linereader.ReadLine.Split(",")(0)) End While
655211, Male, David Graham, 1992, 20, 0411221122I have got the code which displays all the info, however i need to modify it to display only male or females
Dim fileReader As String fileReader = My.Computer.FileSystem.ReadAllText("C:data.txt") Label1.Text = (fileReader)
I have another puzzle to solve and I was hoping that I could get some pointers in the right direction. I have a comma delited text file and I want to write a program that will read the rows and write a report grouping the rows by a column.[code]...
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 am doing an audit of equipment for a charitable organization and have a list of assets (enclosure output.zip) going vertically.
I would like to translate the information from vertical into a comma delimited file, one row per staff member which would be imported into excel and filtered to reporting requirements.
I'm trying to input this into an array and then a combo box using:
dim item as integer dim array() as string dim ifile as integer
[CODE]............
What I want to do is to display the right part of the delimited text (Z920081, Z920082, etc) in the combo box. But when you select the item in the combo box, I want it to use the left part of the delimited text (21, 22, 59, 120, etc) as a variable for other use.
I want to pass a comma delemited list of values as a parameter to a query I'm building using the designer in Visual Studio 2008 based on some strongly typed DAL tutorials I was going through. The query is going against a DB2 database. Here's what I want to do:
select * from prices where customer in(?)
It works fine win I pass in 123456 as ?But fails when I pass in '123456' (it is a char field so I don't know why this doesn't work; it must be adding these behind the scenes) or 123456, 123457 or '123456', '123457' I'm adding this page to a portal where all the data access is being done based on the DAL designer model with a BLL that calls it so I wanted to do it this way for consistency.
