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"""

My project that I had built used spreadsheets and charts within the forms to provide the user with the necessary data. This worked fine for VB2008 as it had all of the ActiveX office web components built into it. It seems that VB2010 has a different set of base components and emphasis office 14.0. I was wondering how people have gotten around this or if they can. I tried using DataGridView, but it doesn't seem to be able to do what I want to do. I need the ability to have users enter data into a table and then use that information to be able to build graphs real-time based on their data.

I have produced some VBA in Access that creates a spreadsheet.I have also created an SQL query that retrieves records from an Access table.I have 48 tables (each table for a specific institution centre).I have created another bit of VBA code that creates a spreadsheet and loads the records from the query in to the spreadsheet.Each centre has a unique Sequence Number (Indent Number)At the moment though, all I can do is import one table (records for one institution) in to a spreadsheet. I want to end up with calling the function and having an output of 48 spreadsheets being saved to my desktop, each spreadsheet containing records of a different center.I have thought about putting a loop in, but not sure how I would quite go about it.
Here is my code to create the spreadsheet:
Public Sub ExcelExport(lngIndentNumber As Long, strFolder As String, strCrit As String, strReport As String)
', ctlLabel As Label,
DoCmd.SetWarnings False

I am using Visual Basic 2008 Express, and just need a line of code for a button to open an application/spreadsheet. Also, is it possible to have a search box open a file automatically?

I have a weird behavior when trying to copy a file with System.IO.File.Copy. The file never gets copied. More than that, the call doesn't generate an exeption!
I am using VB.NET, Framework 3.5. I'm trying to copy in C:Temp and I do have the privileges. Or at least I used to...

I have a form that allows a user to import a spreadsheet. This spreadsheet is generally static when it comes to column headers, but now the users want to be able to include an optional column (called Notes). My code crashes when I try to read the column from the spreadsheet if it doesn't exist.
Dim objCommand As New OleDbCommand()
objCommand = ExcelConnection() 'function that opens spreadsheet and returns objCommand
Dim reader As OleDbDataReader

i want to explore vb abit more and i want to create a VB application similar to a cash register in a cafe or a bar, mainly for touch screen computers/systems. I want this to be for a bar and have a vague idea on how to do it.
i dont want to assign a price statically to a button e.g 'Button1' = "Fosters 2.00" because prices are subject to change, i know this may be possible using a database but i have no clue about them, is there anyway to use excel maybe? and say 'button1' reads from the spreadsheet cell 'C1'.

In my app, I'm downloading a spreadsheet from FTP, moving the data read from thespreadsheet to a DataTable, and, depending on certain conditions, emailing a new spreadsheet (one that contains certain rows from the 1st spreadsheet).My problem is creating the spreadsheet that will be mailed. I can't seem to work out how to add the row from the DataTable (originally from the spreadsheet that was downloaded) into the spreadsheet that's going to be mailed.DS.Tables(0).Rows.Add(ObjSheet.Range(workTable.Rows(i)) - 1)Is what I've got at the moment, but it's not working. workTable is the DataTable where the rows from thespreadsheet were copied to. DS is the DataSet where I'm putting the rows from the specific selection.

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.

I'm writing an application in vb.net 2005. The app reads a spreadsheet into a DataSet with ADO.NET and uses a column of that table to populate a ListBox. When a ListBox Item is selected, the user will be presented with detailed information on the selected record.One part of this information isn't in the DataSet. I have to compare a column from the spreadsheet with several external data sources to determine the nature of the record in question. Here's where I have my problem.This comparison has to search through 9.5m rows in a SQL table at one stage. I've checked and there's no way to "shrink" the query down as I'm already only searching absolutely essential data.What happens is that the application never visibly does anything. The CPU usage shoots up to 100% regardless of what it was at beforehand and the system's performance becomes almost unbearably slow.Can anyone suggest a way I can improve this situation while this massive query is running? I was originally going to write the contents of the 9.5m rows in the database table to a text file which I'd then read from, but after 6.5m rows, I got an OutOfMemoryException.

if any of you have called up excel spreadsheet data within your VB.net app. Is it at all possible instead of calling up access and the like?
And just before some overzealous person puts "we will not do your work for you blah blah blah......" Im not asking you to write it for me, im just asking if its possible, has anyone succeeded in doing so?
Id rather not use VBA script if possible, Id like to create my own app and use a spreadsheet that has all my workings on already - sorry if its a bit noobie to ask such a daft question but one of my friends is going to be opening a restaurant soon and asked me if i could do a little prog for him using his excel stuff

I am trying to write a program that will display an excel spreadsheet in Visual Basic. My goal is for the program to display this Work Order Form I have designed in excel and to modify user, date and auto assign a work order number. After that is done I would like to print the excel form. So I guess my questions are:
- How can I display an excel spreadsheet in win forms
- How can I print the spread sheet after it is modified
- Is there a better way I should be doing this
