Import Spreadsheet Data Into VB 2010 As Variables Array?
Mar 19, 2011
My basic set up is Visual Basic 2010 Express on Windows 7 64 bit What I'm trying to do is to have VB 2010 get the data from a Open Office spreadsheet. I have looked around on the general interenet and have found quite a few references to MS Excel, but none dealling with Open Office. The code samples I have tried to use seem to rely on MS Excel being installed (Which I dont have). The 'Automate excel' page (Here: http://support.microsoft.com/kb/302094) naturally seems to rely on a Microsoft Excel Object Library reference that, not surprisingly, isnt there because I dont have MS Excel. Keep in mind I havent mucked around with a programming code for decades!
What I do have is Open Office 3.2, which CAN save spreadsheets in a excel format (.xls), and a few others such as .ods, .dbf and .xml (Excel 2003?).

I am trying to import data from an excel file but the spreadsheet name is causing problem. If I use 'Sheet1' as the name of the spreadsheet from which I want data, then it works fine but I want to change the name of the spreadsheet to the name which has spaces like 'PROJECT SHEET'. Please guide
Dim ExcelFile As String = "C:ProjectFile.xlsx"
Dim myDatabasePath as string = "C:ProjectsDatabase.mdb"
Dim excelConnectionString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + ExcelFile + ";Extended Properties=""Excel 12.0 Xml;HRD=NO"""
Dim excelConnection As New OleDbConnection(excelConnectionString)
excelConnection.Open()

I'm currently trying to import data from an Excel document to a list in Visual Basic 2010 Express. The Idea is to have the data easily modifiable by the users. I have looked quite a bit online and all of the examples seem to reference either an "Imports Microsoft.Office.Interop.Excel" or "Imports Excel". When I try to use the I get "(no correction suggestions)".

Here is my objective. I have a text file, delimited. Data sample below
1140001074,03/06/12,0001000016,03/07/12,0412652694,1150000309
1140001074,03/06/12,0001000016,03/07/12,0412652695,1150000369
I need to import this data into a table, that is already created in sql. I'm not updating, just a simple insert.I thought the way I would do this is read the file, put that into an array, then from the array import into the table.My code below for reading the text file, and placing it into an array
Private Sub ReadtxtFile()
Dim lista As New Collections.ArrayList
Dim input As String
If File.Exists("C:filetestBol Test.txt") Then

I wanting to try and develop a form that will allow me to import an excel spreadsheet in to a datagrid view, can do that bit with this, Vb.net Information. what i want to be able to do is select which columns in the spreadsheet go where so say i have a spreadsheet with;
ProductCode, ProductName, ProductDescription, ProductCost and ProductMaker
In my DataGridView i have ProductName, ProductCost and ProductDescription.Is it possible to get a list of the columns in a spreadsheet that have text in and then either have a combobox that you select a value from and then after pressing a button it then imports the selected details in to the correct format, (Like mail merge)

I'm trying to import an excel spreadsheet to a bound datagridview. I have a second form which I do all the importing from and update Form1's datagrid view. This part works great. Now, I am trying to update the table that the DGV is bound to, but cannot seem to get it. I know it is probably a simple Update command (which I've tried) but everything fails. It is confusing to me because I create a second dataAdapter and dataSet to import to, then set the BindingSource of the DGV to this new ds. Ideally, I want the Bound table to be empty, then require the user to import on the first run. After that, the imported list would always load.
Here is the code I use to import to the DGV and it works:
vb.net
Dim ds As New DataSet
Dim da As OleDbDataAdapter
Public Sub importDBButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles importDBButton.Click
OpenFileDialog1.InitialDirectory = ""
OpenFileDialog1.Title = "Select the Excel File to import from"
OpenFileDialog1.Filter = "Excel(*.xls)|*.xls"
[Code] .....
My DGV on the first form has a manually added column at index 0 that is a simple graphic. Not sure if this is causing errors, but thought I'd mention it. The spreadsheet that is imported is only 2 columns of the DGV. Do I have to specify data for the other columns? (There's about 16 and I didn't want to have to require the user to fill all that data out in the spreadsheet). How to save this imported data to the bound table?

I've worked out how to display charts in VB 2010 Express, but now I'm needing the user to input data into a spreadsheet/table that will be used within the program. I know that table is no longer available and neither is the OWC11 set. Is my remaining option then to use DataGridView? I know it is SQL based and I don't have much experience there yet, but I didn't want to commit to it if there is another method that would work just as well. The values that are put in by the user does not need to be preserved.

I have to write an application in Visual Basic.Net that will open an excel file, run through the contents an export a test file for processing.
The application works great for me (Windows 7) but when transferred to a WinXP PC gives the following error: HResult 0X800A03EC
I can replicate this error by making the Excel Application visible so it seems like it is an issue where it can't access the file because it is open. Error occurrs when trying open the workbook.
Original Code
Dim excel As Excel.Application
Dim wb As Excel.Workbook

This seems like it should be easy. I have an Excel file that has the information I need, but I don't want to need Excel to run my program. I need to be able to package that information with the VB code. I'm using VS 2010.
I know how to write a program to read Excel and put information into an array, but can I turn that information into something my next program can read independently of the original spreadsheet. This isn't something I have time to input by hand.
I'll try to explain this one more time so that it's clear as mud. I need to be able to incorporate an Excel spreadsheet or VBA code into a VB program so that it becomes independant of MS Office and/or (because it'd be nice to know how to do both) read information from the Excel spreadsheet and then save that array for use in a later program thereby removing the influence of Excel completely.
Finally, I'll explain my program and desired function so that somebody might be able to interperet my desperate ranting. I am writing a program that will require properties of steam to calculate boiler performance. I have found an example of the properties I need [URL] or I might be able to find other sources. I now need to roll that information into my own program.

I have a VB.Net program that reads in a flat file, and then parses line by line, formatting the data into different spreadsheets in an excel workbook (each line can be any 10+ different record types so I parse and put in appropriate excel sheet).
For smaller sized flat files (under 10mb), the parser works great. However, I am trying this on a file that is over 120mb (400k+ lines). While running, I will get an OleDBException saying that the spreadsheet is full. Now I am pretty confident that Excel can handle a much larger data set than a flat file. So I assume this exception is not giving me the true story as to what is really occuring.
I open a connection, and then parse each line in the file, inserting each row into the excel file. I assumed it would be bad performance wise to open/close the connection between each insert. Could this be causing the issue? Any ideas what I need to do to handle such a large file? There are cases where the flat file can be over 500mb.
To actually do the insert into excel, I am just doing the following (I construct an sql query based on the type of row and values parsed):
Dim conn As New OleDbConnection()
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + ExportLocation.Text + "" + importFileName + "-PVF.xls;Extended Properties=""Excel 8.0;HDR=YES"""

So I'm a little rusty on my VB.NET skills, but I decided to take up a project to get me working in it again. Problem is I've hit a slight road block and I was hoping someone here might be able to point me in the right direction.I have a spreadsheet (or 3, but they could be combined if that makes it easier) that contain interest rates. I need my program to use user-input to select which interest rate it needs and then calculate and output the grand total, without the end user ever seeing or even being aware of the interest rate table.

So I need to create a windows form that is able to generate reports by querying a SQL Database or SQL Server. There is data in the databases that will be put into an excel file from whatever columns from a specific table I need. I need it to be a dynamic query that is probably hard coded into the application because I might need to write other queries at some point to generate different reports that need different columns.
What I need is somewhere to start or some code that I can look at because im not very familiar when it comes to vb.net/excel. I need code to get all that data from the database and put it neatly in an excel file and I would like to specify what columns in the excel file all the data goes under.

I have an project which was written in VB6 and made use of the Spread3.0 component to display multiple large data from database in spreadsheet. My objective is to convert this project into a VB.NET current version which would not use the third party component but can possibly use a freeware that does similar if not all the functionality.
My question is, are there any freeware that is available in .NET for such spreadsheet-like manipulation of data programatically? I have come across dsoFramer but this only allows the display of the data in an IE frame. I would like to jus embed the content into my existing form.
Also this freeware must be able to handle formula and user-editing as well as multiple cell type such as combobox/checkbox etc.

I have a program that currently takes data and writes it to a MS Excel spreadsheet. (automatically opens the program, creates the cells, and fills them with data)
I would like to add an additional feature to my program that offers support for OpenOffice.org's 'Calc' spreadsheet program. (so users without MS Excel can use the application) So I am basically asking if anyone knows how to automate OpenOffice 'Calc' from VB.net. (I am using Visual Studio 2005)
I have searched on the OpenOffice forums but no one seems to know the vb.net code for this. So I was wondering if anyone here has done this, or would know how to do this.

I have been on MSDN about this and searched but it's not quite telling me what I'm after. I've extracted a list of file names from an Excel spreadsheet and want to check whether they all exist in a directory which a user can select in a text box. It feels like I'm nearly there with it but currently my listbox is displaying everything, I want it to just show the files that are missing. I'm a beginner so I'm not exactly sure if I'm even telling it to compare the two things properly, I've tried a couple of ways of checking if a file exists but neither seem to work.[code]
