Exporting DataTable To Excel?

Feb 10, 2012

I have been trying to export a DataTable to an excel file and have been hitting a few wallsI am using Visual Studio 2010, VB.Net, Windows 7 64-bit, Office 2010 32-bit. 1) I first had trouble with not closing the Excel.exe *32 process and solved that by using the FinalReleaseComObject(ExcelFile).2) When I use the FinalReleaseComObject, it re-checks the "Ignore other applications that use Dynamic Data Exchange" under Excel's Options-->Advanced. Then any time I try to double-click on an Excel file, I get the error: "There was a problem sending the command to the program." Excel opens, but the worksheet I want does not. The only solution I have found to this problem is to have the DDE unchecked

Private Sub PrintTable(ByVal data As DataTable, ByVal FileName As String)
Try
Dim priorSum As Integer = 0

.net - Exporting To Excel Removes Leading Zeros. Css Styles To The Table Does Not Carry Over To The Excel Export?

Aug 4, 2011

I have an asp:table which I want to exported to excel. One of my fields are alpha numeric and when exported to excel the leading 0s are stripped off. After going through this thread: Validation (CSS 2.0): 'mso-number-format' is not a known CSS property name I would like to use the css method "mso-number-format:@;.But the css is not exported to excel. I just tried to test it with simpler css things like bold font etc but its not getting carried over. I can see that if I surround my asp:Label with tags this change gets carried over to the excel but not the css bold . Other solutions in other thread does not work for me as ="00111" shows up as desired in excel but in the web form it shows up as ="00111" which is not what i want.

Exporting To Excel - Get Excel To Return Down A Row And Display The Next Product Within The List Box?

Apr 16, 2011

I am building an ordering system for my job. The idea is that the customer will put in a stage name for an item. That stage name is then interpreted by the program.The product id and the amount the customer wants to order is placed in a list box on the form. There are a couple of buttons, ADD, REMOVE, CLEAR, and EXPORT. The user input is handled by input boxes. When the user pushes the EXPORT button, excel should open and list out the interpreted product codes with the corresponding amount to order. I can get excel to open, but I can not get excel to display more than one line. It will display the first product, but then it comes up with an unhandled exception.I can not figure out how to get excel to return down a row and display the next product within the list box.

Exporting DataTable To CSV?

May 26, 2006

I am attempting to create a CSV file based on a datatable I am using in VB.NET

I can successfully write the data table to CSV format however my problem is that because the default data type for the columns in the CSV file are General ,any Text I pass through with Numbers in it that are preceded with zeroes (i.e. "001") will get written to the CSV file as "1" without the 0's. I need this to be treated as a text string so "001" gets written in to the CSV file.

Is there any way to do wthis or specify through code what data type the column will be?

Here is a sample if the code I am using:

Exporting A DataGridView To Excel?

Mar 13, 2006

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.

Exporting Excel 2003 To Pdf?

Sep 12, 2011

I have a vb6 app that creates an Excel 2003 doc that I need to export to pdf. I have the following code to export,

excelWorkBook.Worksheets.PrintOut Copies:=1, ActivePrinter:="Adobe PDF",' printtofile:=True, prtofilename:=strOutputName

but nothing prints. The app exports to pdf works in test, but not when I move it to production. I have to remote into the machine that runs the app, so my printers from my local pc are "attched" to the remote session, can this have something to do with no output. The remote machine does not have the Adobe print drivers installed.

What can I do to get the export to work?

Exporting To Excel From DataGridView

Jun 22, 2010

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.

Exporting To Excel In A VB Windows App?

Oct 20, 2009

I have a windows application that exports data from a datagridview into excel. Now this data can change based on what a user does in the datagridview itself. An example would be out of 1,000 files the user can sort through using DataGridViewAutoFilter to search for a handful of rows, say 50 or 143 or whatever.

The user then clicks on the button which exports to the excel worksheet. I'm looking for some help on getting a subtotal count at the bottom of the export. I would like to be able to have some additional code in place that would subtotal the records that the user exports into the worksheet. Let me show you what I have so far:

Charting With VB 2010 And Exporting To Excel?

Jun 7, 2012

Im doing a project with .Net 4.0, Visual Studio 2010 and Visual Basic .Net.I needed to add a Chart (the new one included by default in .Net 4.0) that represents temperatures evolving with time, so I added the drawing points in the elapsed event of the timer every second.The graph is doing somewhat ok, but I need another functionality, and this is, every time I stop the timer, save the graph in an excel (.XLS or .XLSX) file. As by default the chart provides with a collection of the type "System.Windows.Forms.DataVisualization.Charting.DataPointCollection", I would like to know if there is a way to create an xml and put the info of those collections in the excel file.I have looked around but I didn't find any similar example, last thing im thinking about is to use an iterative way to manually write in the excel file, but maybe its too much time consuming as the iteration will be of several thousands seconds.

Exporting Data From A Datagridview To Excel?

Jul 28, 2010

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;" & _

Exporting Excel Range As Image?

Dim rgExp As Range: Set rgExp = Range("B2:C6")
''' Copy range as picture onto Clipboard

[code]....

I am running into trouble converting the ActiveChart.Paste method. I can't get it to work in VB.NET. It either throws an error or It just leaves an empty box when I do it in VB.NET (if I add .chart before the paste it runs, but doesn't paste any values), but in VBA it fills in the values of interest. I have tried creating a chart object, but that did not seem to work either.
