I decided on a comma separated data file, saved as a text file. This is for data that will not change. After loading the data from the text file; then throughout the lifetime of the program the data can change. The data can then be saved back to a different binary file. The idea is to have a save state system going.Does anyone have a suggestion or is opposed to the idea. Is there a simpler way to organize something like this?
i have code for loading a text file (comma separated) into my DGV:
If Not DataGridView1.LoadTextFile(TextBox1.Text, ErrorList) Then Dim sb As New System.Text.StringBuilder sb.AppendLine("Failed to load text file, see error messages below.")
[Code]....
I'm wondering...is it possible to run this code if the user was to drag and drop the text file onto the datagridview, rather than having to navigate via buttons etc...it'd make it a much nicer method!
These is the content of my txt file which is saved in D drive in my pc abc,1,2,3..I tried the flowing but it didn't work:[code]I am getting error on this line.. data = line.Split(","c)...it says this line isn't in use anymore or something and that I rather use LineInput but thats asks for filenumber and i don't know what that is. I am sorry but I am a complete beginner. what else can I try? [code]ok that error is gone now but now if I want to add these values to a list box..how can i do that?
I'm brand new to visual basic and I've been given an exercise to extract data from a text file. I can get the lines of data to read in and can get the names out using the following code. How can I extract the department i.e. sales and finance also using the mid and instr functions? I also need to be able to list list the people by department using a dropdown combo box.
What my problem is that, how can I load this .txt file to a datagrid and arrange it in a 3 columns. That .txt file is auto generated that's why i cannot do anything about the textfile.
This is my first 'serious' VB2008 project. Attempting to write a comma separated file. vis:
[Code]...
Is there a better method for outputing the data, rather than having to concatinate all the elements into a string and then writing it? In the 'good old VB6' days a Print statement followed by each value and a separator would do the trick. I can't seem to find the appropriate override for the WriteLine method.
I'm attempting to add comma delimited values to a combobox. The problem is I do not know if this is the best way to split the values into the combobox. Is there a more cleaner/efficient way to do this?:
Dim toread As String toread = ini.ReadValue("Schools", "Schools") Dim textdelimiter As String textdelimiter = "," Dim splitout = Split(toread, textdelimiter) Dim i As Integer For i = 0 To UBound(splitout) ComboBox1.Items.Add(splitout(i)) Next
When I look at a file on my hard disk, e.g. test.csv, when I look at the Properties of the file, it is officially known as, "Microsoft Office Excel Comma Separated Values File", and file types of .pdf are listed as "Adobe Acrobat Document", etc. etc. All of this information can be seen in Windows Explorer too when my folders are displayed by Details. How do you get at this "type of file" information with .NET?
I'm trying to read a csv file with comma separated. Problem is inside the file, it has one column which original value already contains Comma. Here is the example
[Code]....
So, when I Split the string with Comma, it gave me problem. Actually total it has 6 columns. But because of internal comma, it gave me 7 columns. And this CSV format can't change so I must deal with this problem. And so here I come out with a solution (because of its too long, I looking for better idea and solutions from you guys ):
I'm having a little trouble with this... I have a Session variable which contains a string of comma separated ID's which needs to be passed to a stored procedure but if it is more than 8000 characters, it needs to be split into more comma separated strings. For example;
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 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 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.

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 have my datagridview being loaded from a Text File and then being saved to a text file as a comma separated file - the commas obviously separate the columns. However in some of the cells prior to saving, I have data that i have inputted over two lines by pressing shift + return.
E.g. "SOLD 10/05/2012"
This saves fine, but obviously shows up in the text file as a line break, which then causes some issues when I choose to re open the info back into DGV. How I can code so that it saves as a line break within a cell, rather than a completely new line.
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 have problems to print the records which is saved in text file. It prints whatever in between the textfile but does not print whatever contents in the textfile.
Public Class Form1 Private Sub pd_PrintPage(ByVal sender As Object, ByVal ev As Printing.PrintPageEventArgs)
I'am creating a script editor for my own purposes.And i have a menu option called "Close", and i want to check if the file is saved or not, so it no code get lost by clicking wrong.
Anyone have a idea how i check if the file is saved?
I used a built in function to create comma separated string using List easily.(It is not split and join but new function) I'm not able to recollect or find it. If some one knows about it and uses it please post a link to that. Framework - .net 2.0
(It is not Join or split - I know about this, .net has new built in function to create CSV format)
Check Jacob G Answer below for what i was looking for let me know your thoughts on it compared to join ;)
And whoever gave me -ve rep need to keep some patience and not hurry
