Exporting DataGridView To CSV File
Jan 24, 2011
I have the following code:
Public Class Payrollfinal
Private Sub Payrollfinal_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub payrollsubmitButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles payrollsubmitButton.Click
[Code] .....
And when two things happen when I try to use this code (which I modified after finding it on another site)
1. Intellisense tells me that MyDataSet is not defined.
2. When I define MyDataSet as
Dim MyDataSet as New Dataset
Intellisense tells me that I'm told that AppendText is not part of String.

I have a form that I'm writing that will run a stored procedure, present data from that stored procedure in a datagridview and then allow users to export that data to a csv file. I found the following code:
Code:
Imports System.Data.SqlClient

Private Sub Payrollfinal_Load(ByVal sender As System.Object, ByVal e As

I have the following code:
[Code]...
End Class and what intellisense is telling me is that MyDataSet is not declared (I took the code for this portion from another site and modified it to suite my needs.) I tried adding the declaration Code: Dim MyDataSet As Dataset but when I added that, where ever there is a .AppendText statement, I'm told that AppendText is not part of String.

I have a a DGV with the following fields:
FirstName
LastName
Address
Job
StaffNum
Nationality
DOB
Notes
Picture
FileName
Now my DGV has records in it and I try to export it to Excel File. Now it exports the the Column Names above but none of the records. My code is below.
Dim fs As New IO.StreamWriter("C:exported.xls", False)
fs.WriteLine("<?xml version=""1.0""?>")
fs.WriteLine("<?mso-application progid=""Excel.Sheet""?>")
fs.WriteLine("<ss:Workbook xmlns:ss=""urn:schemas-microsoft-com:office:spreadsheet"">")
fs.WriteLine("<ss:Styles>")
[Code] .....
I got this code from the MSDN forums from a link someone posted. They said they changed IntCol and it worked to incoude the records as well but I cant figure it out. When I hit Export it does prom,pt me to save the file and saves the Names above to excel sheet but none of the records.

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 have a datagridview(DGV) which contains data based on a user selections from a pre-defined dataset
In point form:
User starts program
program builds datatable
user opens file and program read all data from file into the dataset.datatable
user defines the data they want to see
program displays datagrid based on dataset.datatable and user choices. (basically it displays the whole dataset and removes unwanted columns
ecords)
I want to be able to export the datagrid to excel (not sure which method yet). I have tried the excelexporter component i found somewhere on the msdn forums (it exports the data to look exactly like the datagridview) but its painfully slow. It exports something in the region of 100 records per minute. Most of the time, the datagridview can contain anywhere from 3000-32,000 records. As such, at 100 records per minute, the excel generation can take updwards of 50minutes. Unacceptably slow for the purposes of the program.
What do people recommend as the best method to quickly dump the contents of a datagrid into excel. By quickly, im talking at the speed of about 10,000 records per minute. In all honesty, anything over 5000 records per minute will be fast enough, but the quicker the better!
Is there a way of creating a new dataset.datatable that is built of the contents of the datagridview and then building an excel sheet by connecting to the new dataset?
I would like to be able to export to Excel 2000-2003 at a minimum, but if i can do excel 97 as well it won't hurt.

I found some code online that describes how to export from a DataGrid to a CSV file.
It creates strings just fine, but when I go to save it (writeline) it breaks.
First, here's the code.

I have to export a datagridview in a word document, i already started by creating a header but I don't know how to export my datagridview. I'm a starter in programming vb.net.
Here's the code:
Imports Word = Microsoft.Office.Interop.Word
Public Class Form2
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim oWord As Word.Application

I am filling a datagridview with very lengthy results. Roughly 60k rows on average. I am filling them via an oracle database using a table adapter. The records then have a filter placed on them in the datagridview so the results displayed are a bit different.
My problem: I built an export to excel function which populated a dataset and then red through it and wrote to excel. Bad idea with the amount of records I am using. I tried just writing the records straight to a csv file using streamwriter but I don't very much like this way.
My proposal: I would like to fill an array from the datagridview and then be able to dump the array into excel. However I am having some trouble finding examples on creating an array from a datagridview.

I'm using this to export an unbound datagridview to a csv:
Private Sub subExportDGVToCSV(ByVal strExportFileName As String, ByVal DataGridView As DataGridView, Optional ByVal blnWriteColumnHeaderNames As Boolean = False, Optional ByVal strDelimiterType As String = ",")
Dim sr As StreamWriter = File.CreateText(strExportFileName)
Dim strDelimiter As String = strDelimiterType
[Code]...
It works great but the only thing it doesn't write is the column headers. I can't figure out why it won't include them in.

I am using Visual Studio 2008 and looking for an efficient and hopefully straightforward approach for exporting data from a DataGridView to Excel. If doable, my preference would be to export the data to Excel without instantiating an Excel application. I found some code on the Microsoft support site that is fairly accessible but the example shows how to export just a few pieces of data. Would someone be able to demonstrate how to modify this code to so that it could be used for large amounts of data (for example, data from a DataGridView).
'Establish a connection to the data source.
Dim sConnectionString As String
sConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _

What I'm looking for is a snippet on how to export data from a datagridview to an access DB. My other question is fairly simple what code would I use once the data has been entered to account for the addition/subtraction. I know these are fairly
simple questions with probably incredibly easy answers, but once again the first time I've picked up a programing language was a week ago. Hey trial by fire works 70% of the time all the time.

I have a datagridview which I would like to be able to export the information to an Excel spreadsheet, and be able to reload the information later on from a specified worksheet. Also, I'd like to avoid using Databases with Access etc because I am aware that some of the machines I'll be deploying the program on do not have Access installed and would not want to have to install it either.

I have a problem on Data Grid View.Actually, i need to transfer data from a VB 2005 form by clicking on the form which consist of a two dimensional array grid - Infact the form will consist of a picture on which a 2 dimensional array grid, which would represent the various coordinates on the map. The user will have to click on the points on the grid to export those results to the x an y coordinates on a datagrid view.

** Edit - just thinking - I have this export code elsewhere in my application; testing it with blanks works fine. All the fields in the two forms are text fields. The only difference that I can see is that the form that is causing me a problem is based on a left join query from my database; the form that works is based on a flat table. Any ideas???
I have tried everything in my (very, very limited) knowledgebase for VB and am completely stumped. I'm sure the fix is simple, but no clue where to go. (I got this code from a site which I didn't make a note of, and cannot find it by doing a google search)...
The code listed below is supposed to export a datagrid view to CSV. It works fine - if, and only if - all the fields are populated. If one of my columns is blank, then I get a ""Conversion from type 'DBNull' to type 'String' is not valid." error. **Edited to provide exact error message
The code that's giving me a problem is the second IIf(intRowData < intColumnCount, strDelimiter, "").

I already exporting contents of my datagridview to excel and word but I need to format one of the column of my datagridview. That column is "Amount". In my datagridview, it displays like this "122234". I want to display all the value in that column in this format: "122,234.00". I already tried to format it to number("N") in my datagridview but when I exported it to excel and word, it shows no format.[code]

I need to export the contents of DataGridView into an Excel file. There is lot of discussion which I went thru and leaves me more confused now than before. I am using VS 2010 Express with Office 2007.

Not the current time, but the time when a file was sent. It displays correctly in the DataGridView but displays 12:00 AM for every row in excel. I'm adding it to the DataGridView like this:

I am writing a program that uses several textboxes that a user will fill in and then click the add button to add the data into the datagrid. There is no backend database or anything. Just seeing the data in the program only.
What I want to do is then export this data from the datagrid into a file, preferably excel.
I've done copying textbox data into txt files but I can't find a method to copy datagrid data into a file.

Currently I am building an application that will do Data Validation on an Excel Spreadsheet.The application will allow a user to load an Excel Spreadsheet in and runs checks on the data. The application needs to export the spreadsheet as a pipe delimited file with all of the fields separated by the character.Currently I have written an Excel Macro that will export it as a Text File then delimit it and save the text file as a .ps1 file. I cant seem to figure out how to write this same code in VB instead of VBA.I am currently using Visual Studio 2010.Here is the code for my Macros that work fine but I need it in the application and not on the spreadsheet.

I have a field that needs to be 10byts long. However, if the number does not use all 10 bytes, then it will need to have zeroes in front of it.say you have a Check number of 12345, well in the text file it would need to show up as : 0000012345..This is the code I'm currently using but when I open the text the other 5 remaining bytes are just spaces.
