I have created a database to house a lot of data. I have created a front end application to allow the users to enter the data and it gets checked and then written to the database. The problem I am having is the users have a lot of data that has been kept in Excel sheets and they are wanting to import the data to the database without having to reenter all the data.I have been reading through the different posts trying to find one that will fit my needs and haven't been able to. The old way of putting the data into Excel has now been turned into a few different tables in the database. The database is created off a national standard so it can't be changed. What I am needing to know is how to take data from these Excel sheets and import either into my application and then find a way to covert the data over to where it can go into all the tables that need it or to create something that will write the data directly to the database into the different tables.

I am being given excel sheet daily and want to upload them to an existing database with the exact same column names, i wanted to do this in sql server 2005, but then i thought it would be easier to just creat an asp.net program that could do this autmatically, that way the managers could do it them selves. would i use a bulk insert?
I have a simple Windows Service that reads from an Excel spreadsheet and imports the records into a SQL Server 2000 database table. Before it loads it checks if the file has been successfully imported before (using filename) and whether any of the records in the file have been imported before (using primary key). If these checks are ok I load the records into a datatable and then update the datatable to the database.
However, I need to do this in a transaction as I want to ignore the whole file if there is an error. The file goes to a discarded folder and the user gets an email with why the import failed. (This is likely to be because the store the record is for is not yet added to the database and the referential intergrity of the db fails). If there is no transaction the records before the failure record are imported. When the file is imported again (the store has been added to store table) the file is then rejected because duplicate records are already in the db.
I have read some of the other posts on this and seem to be a little different than my situation. Trying to print out some reports into an excel document on the clients machine - of course it works fine on my local (heard that before right). I went in and set my references Ms.Office.Core and Ms.Office.Interop.Excel to 'Copy Local' = True so the .dll are in the servers bin folder.
We have a VB 2005 program that reads data from a database and builds an Excel output file to be emailed. This works fine from my computer but when we put it on the server it fails on the Excel functionality.
The error is: Unhandled Exception: System.Runtim.InteropServices.COMException
Although Excel is not installed on the server we did also build a Setup program to install our program. It copies the Microsoft.Office.Interop.Excell.dll to the server folder with the exe.I thought the setup program should register the Excel DLL and the program should work even if the server does not have Office or Excel installed.
I am trying to do something fairly simple.. allow my user to import thier data from Excel into SQL Server, where it can be used by the application.To do this, I'm using the fairly simple code that is common everywhere I look:
Now, on my development computer this code works perfectly. The data imports, and I can go on my merry way.
On the TEST computer, this code throws the error: "ODBC -- Connection to {SQL Server} servernamesqlservername failed." This seems very odd to me, because I'm using exactly the same SQL Server and database to interact with the application, and all the other screens in the application work perfectly. The test computer CAN connect to this SQL Server, but it keeps throwing this error whenever I try import data from Excel.I've tried everything I can think of - using the server's IP address instead of the server name, sending the SQL Server administrator data along with the request, taking out the Trusted_Connection=Yes... nothing works. What is going on here? How can this code work fine on my computer, and hiccup on another?
I have created my site using ASP.NET Personal Starter Kits 3.5. I use Visual Studio 2008 only . .with its built-in SQL Server (2005 Express) ... my database in App_Data is ASPNETDB.MDF ...I have created some of my tables also ....in ASPNETDB ..In my local PC the site was running fine ...But when I publish my site on production server it doesn't work and shows the following error
I have developed a VB.NET program using a strongly typed dataset. This dataset has its connection to a SQL Server 2008 R2. The software should now be additionally used offline. The database should be exported to a *.sdf database. If no connection to the SQL server is produced, the software have to try to connect to the *.sdf database.I would like to achieve:
1. Export the data in the SQL Server 2008 R2 database to a local *.sdf file.
2. This *.sdf file has to work as an alternate connection string in the strongly typed dataset.
How can I write a connection string? I has four different computer that can be connect via ethernet.How can I maintain a inserting data if to computer insert on same table at a single time..??
I am tring to make the below application work with SQL Server 2005 Database Currently it works for test.mdb, which is in the same folder with the application. How shoud I modify the MapPath to work with SQL Server.
i have a app in visual basic mobile 2008, so i finish but now i need to tranfer the data generate in the in the app mobile to data base in sql server 2008.
I recently upgraded the MS SQL Server installed on my personal computer from 2005 Express to 2008 Express. Problem is when I try to add an SQL database file to a project using VS 2005 I get an error message saying that the version of my database server is not supported, I must have SQL Server 2005 Beta 2 or later installed. I didn't do it yet but I'm pretty sure that when I open the other projects that I included a database file to it, I'm going to get the same error. My question is it possible to have two SQL Servers installed on my machine? If so, is it a good idea to have two DB servers in the same machine?
Ive created one database Sql Server Compact Edition 2005, with one table ("Cliente") I know that I can created my database good, but i have a problem saving information since three textbox, in my table(With columns "Nombre" "Apellido" "Cliente". In my form there is a button save ("Guardar"). When I do click in my button appear the next message : "The column cannot contain null values. [ Column name = Nombre,Table name = Cliente ] " and happen the same with apellido and Id_Cliente. And this happen becouse my code cant save the information....
This is the code
Option Explicit On Option Strict On
Imports System Imports System.IO Imports System.Data
[CODE]...
And the code for my button is:
Private Sub cmdguardar_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdguardar.Click
Dim myconnection As SqlCeConnection Dim mycommand As SqlCeCommand
before re-inventing the wheel, i want to ask you how i can do this best: I have a VB.Net application that uses a database connection to MS SQL Server 2005 (express version). There are users that input data with the application into the database lets say once to 2x an hour to once a minute. I want to do backups like this: Once a day or once a week (in the evening) a full backup, and whenever the program/user is idle for lets say 10 Minutes, i want to do an incremental backup (so that it does not take so long until he can work on after the backup).
There are no big security issues, just copying the backup data files to a network share / a different computer or server would be fine. i guess the average db size may be 300MB, but the daily increments about 1MB.
I work with vb.net I have a sqlServer database and i need to migrate to a DBF database.I know that a dbf file sctructure is a hexadecimal text file.I want to generate this file without a provider...building this file with this hexadecimal structure.
I have a problem here... I'm using SQL Server as may database and developing that database in Visual Studio 2008.my problen is, when I use the STORED PROCEDURE from SQL SERVER it doesn't update/save new data on a the table. here's my coding; This is my stores procedure: when I execute this on on SQL SERVER it worked perfectly.
I am trying to make a copy of an existing database, I use .net framework data provider for SQL Server.I get error "Unable to connect to source server for Transfer" when it runs to oPackage.Execute().
oConnection = oPackage.Connections.New("what the providerID should be?") oStep = oPackage.Steps.New oTask = oPackage.Tasks.New("DTSTransferObjectsTask")[code]......
I have developed some software(vb.net) that records fees paid by the students. The purpose is that the database should be stored in a server, which can be accessed from any stations linked with it.This is working fine with a network of 10 computers. I need to publish it over the net so people could do this job logging in over internet. Database (access database) should be stored on a web based server.
I have to write a code in vb.net (2010).To get a data from Database A table 1 and dump it to Database B Table 2.What's the best way to do this? Most efficient way? I know I can do this very easily in sql management studio but I need to write a code to do this in vb.net.
Everything seems to imports ok until i look at the data in more detail, this is when I notice its imported the data but in the wrong order.
for some reason when I look at the db table all records are in the wrong order, and strangely enough it seems to be a different order every time I import things.
Is there a way to force the routine to import the data in the same order as the it is in the excel file?, because at the minute it seems to have a mind of its own[code]...
Does anyone know how to import exel data into sql server using vb.net? I want to create a openfiledialog and allow user to choose which exel file to be imported into the server.

I created a vb.net RTD server as explained in the link below in vb 2008 express. [URL]. But this link gives no indication of how to register the dll on another machine. I tried to register the dll using regasm, but it still doesn't work. (I keep getting #N/A s).
I'm programming a file transfer between my computer and a FTP server.I can download the file from my server but I can't load a File from my computer to the server.I use following code for it:
