I'm sure this is a common problem but I have been unable to find a good solution anywhere.I am using line.Split to read a CSV file.Unfortunately the data contains strings that have comma's in them like so:
"Singer","Hasselhoff, David",21,15
This results in 5 strings:

I want to export data from a DataGridView to a CSV/text file. I then also want to be able to load that same CSV/text file and populate that same DataGridView at a later point in time. My information is loaded into columns in the DataGridView. That is, I am not using rows to represent records, I am using columns. As such, I need to load all the data in each column and export this, by column to the CSV/Text file. Likewise, when I load the control from the CSV/text file, I need to load each column with this information.How do you export/import from/to a DataGridView controlHow do you organize the data in the CSV/File

I'm new to using CSV Files, and I've been looking around for a few hours now for a good example on them and no luck. This is what I have so far, which does work.[code]how to ignore commas within the file... for example lets stay Data Entry Guru entered 78 Main St, Apt 1 and the raw file reads ,"78 Main St, Apt 1",Anytown, CAI would like 78 Main St, Apt 1 to be one "field", Anytown another and CA another.

I am loading a dataset with a csv file.I remove the quotes around each field in the csv file and I am splitting each field wherever there is a comma:Dim fields() As String = lines(i).Split(","c) The problem is that some of the fields have a comma in the csv file (surrounded by double quotes).How do I replace those commas with a space to avoid problems when loading the dataset?

View 4 RepliesI want to read a text file that has multiple lines and commas on every line, every comma represents a value, like an integer or boolean. here is an example
50, 100, 50, 50, True, "C:WINDOWSWhatever.jpg"
I want to read each individual line from the text file and read the values after the comma's.
So the first value would be a picturebox height, the value after the second comma would be the width, the value after the third would be the top, after that the left, and then stretch image, and the location of the image. How could I do this?
Here is a simpler version.
Height, Width, Top, Left, Stretch?, ImageLocation

I'm new to Comma Delimited values. What I'm trying to do is load up a text file which has employee info separated with commas
like 1/1/09, John Smith, (555) 555-5555, 101 S 1st Street and has numerous rows of info like this
so what I want it to do is just write this info to 4 different textboxes
like txtdate would just have all the dates of employees listed in rows or multilines
then another text box for names and so on.. Right now I just have it all being written to one text box.
I'm not sure how to separate all the information accordingly.

I am trying to import data from a server and put it into an excel sheet. I have included (imported) the Microsfot.Office.Interop package into my program. I have been looking through the Object Browser to find the correct commands to add this imported data. Should the ListColumns.Add and Listrows.Add functions be used in this spot? I have started a code however, it was initially going to be used with human interaction. The new direction is to make it automated. The section of code I have written follows:
#Region " (Import Data) This function will import the PI Tag Names and desired Attributes into an Excel worksheet "
Private Sub Import()

After the nvs.Add("changer", 1) there are many more attributes that are going to be added to the excel file but I did not feel they needed to be shown here.
We have a legacy application that is dumping large volumes of data to tab delimited files.Each file contains a single record type and all fields are fixed length.These files can readily be imported into corresponding tables in our SQL server database using the BCP utility from the command line.We have a VB.Net program written in VS 2003 that imports these files using the SQLDMO.BulkCopy routine. We are updating the system to use VS 2010 with SQL Server 2008 and according to the Microsoft documentation SQLDMO is no longer available.I have searched on the internet and have rewritten the import routine to import the tab delimited files into a DataTable using the Microsoft.Jet.OLEDB.4.0 provider. The SqlClient.BulkCopy object is then used to import this DataTable. This issue I am having is that fields in the tab delimited file that are set to spaces are being treating as NULLs when imported into the DataTable. When the DataTable is processed by the SqlClient.BulkCopy the copy fails because the null values are rejected by the SQL table fields that are defined as NOT NULL.Code being tested is shown below
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
