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?
I have a machine which creates a new log file at the beginning of the day(12am) and updates the log file whenever there is any changes until the end of the day. How do I import the data in real time (30 sec, 1min or whenever there is any changes) to my SQL server database? Will SQL Server 2008 be able to access the active log file? If not will it be easier if I let my machine create a new log file whenever there is any updates? But if it is so, how do I import so many log files with different names in real time. (I must be able to scale the solution up to multiple machines).

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.
I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.
The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.
For what it's worth, the relevent part of the query is:
Select [Date Created] From MyWorksheet
Iam having difficulty with what should be a simple program.I am trying to access a MS Access Database file (2003) using VS 2010 Visual Basic.It is a basic application of opening the Access database file and retriving informaion from one row of data.

View 3 RepliesI tried Firebird with .NET Provider yesterday. Firebird was sure to beat SQL Compact Edition. I was amazed from it's features and precision. But I felt sad when I wasn't able to find updatable RecordSet/ResultSet features and functions in the .NET provider. FBResultSet doesn't contains anything, no rows addition, creation, modification, nothing. Anybody knows if this feature exists in Ado .Net provider of Firebird because there's no documentation.I would like to receive help because I am waiting to integrate Firebird in my freeware application.Also, if there's are replacement functions for implementing updatable RecordSet, ResultSet.
View 1 RepliesI've created a small DLL, an addin for Autodesk Inventor, this addin saves some information provided by the user and the program to an access(mdb)database.The whole idea behind this is that it allows users to quickly find drawings, assemblies and so on.The DLL works great on x86 systems however it has issues on x64 because I used ado.net.In a attempt to solve it I forced .net to compile it with the target x86 CPU settings.
However using this I'm unable register the dll (C:WINDOWSMicrosoft.NETFramework64v2.0.50727RegAsm.exe /codebase SavetoDatabase.dll )It says its not a proper .net dll file and therefore cannot be registered.
is there any other access-database connection provider (like dao or ado.net) that works on a 64 bit machine? Or do I need to change from mdb databases to another type (like mysql)? because sooner or later all machines its running on will be converted to x64.Or do I need to register the dll in another way?I've also tried to replace the conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0 with ACE, with no luck however

VS 2010, VB.NET, WINFORMS. In my app i have a need to import foxpro database tables and exclude the deleted records. The problem is that FOXPRO tables keep deleted items inside the same table. I have tried using DELETED=NO in the connection string but vb throws "Format of the initialization string does not conform to the OLE DB specification."
My function is as follows:
Dim _DBConn1 As String = "provider=vfpoledb.1; Data Source = " & file1 & ";DELETED=NO"
Dim _DBConn2 As String = "provider=vfpoledb.1; Data Source = " & file2 & ";DELETED=NO"
Dim _DBConn3 As String = "provider=vfpoledb.1; Data Source = " & file3 & ";DELETED=NO"
Google results pointed me in the direction of DELETED=NO but its throwing that exception error now that I have added it..

Provider cannot be found. It may not be properly installed.
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 am using a database file Database1.mdf which have a tabel called student. This Database1.mdf is simply added by using the option Add New Item in Solution Explorer. The problem is that I am to able to update the database through form and code. The code is as:
Dim conn As SqlClient.SqlConnection
Dim ada As SqlClient.SqlDataAdapter
Dim cp As SqlClient.SqlCommandBuilder
[code]....
The ds is updated at run time, but as form is closed and run again the actual database table student is not updated.I have no idea what is going on. The same code work right with Access database and SQL database but in this case it is not working. I've tried on google but not getting satisfactory answer. I've also seen a post on this site but that is about ConnectionString, not about the database update.

At the moment i have an access database file just sat in a folder on my employers server which every computer can see. We can all run an application i have done which we can add/update/delete records/rows on te access database.I was told that access can be temperamental if too many people are using it at once, and that i should look into changing it to a sql server database ? Can a sql database just sit independently like the access database and is it just similar code except for the connection ?
