View 5 RepliesWIndows 7 Won't Run .NET MS Access Database Connection Program, But XP Mode Does?
Mar 16, 2010I have written a simple VB.NET program that connects to a MS Access Database. This program runs in Windows 7 XP Mode, but does not run properly in straight Windows 7. Somehow, the Windows 7 does not connect properly or read the MS Access database data properly with the DataAdapter.Fill method. I have dual monitors, so I can run the identical program side by side (one in Windows 7 and the other in XP Mode) - one works and the other doesn't (it doesn't crash, it just get "nothing" from the database when accessing - acts like it's not connected). Has anyone else run into this, or similar, problem with VB.NET and MS Access connectivity?
View 14 RepliesMake An Oledb Connection To An Access Database : Invalid Authorization Specification
Sep 15, 2007I am trying to make an oledb connection to an Access database.
1. I added a component class.It said drag from the toolbox to add components.
2. I dragged over the Oledbconnection and OledbdataAdapter
3. I clicked on new connection string for the oldeb Connection and try to connect to the SHX.mdb datababase in the debug/ bin folder I don't have a username or password for the database and do not want to set one up.( is this possible in .net?)
4.As soon as I try to test the connection, I get the "invalid authorization specification" message. I can't get past this and do not really understand why I am getting this message.I have vb 2005 standard edition, not express edition.The exact same thing happens when I try to set up the data adapter to the shx.mdb database.
I am on XP2 and not logged in with a password or username. Could this be the issue or is there something else I am overlooking.Also, since I am coming from vb6 and ADO is there anyway to just write the code without having to use datasets, adapters and oledb connections to bound controls?
Database Connection - Post-install - Created A Fairly Substantial Program
Aug 7, 2009Over the last couple months I've created a fairly substantial program for a friend in vb 2008 express to deal with the management of a fantasy football league, for its data storage it uses mainly an sql server 2008 express database for all the data, however there are a couple of text files for some unrelated fixed values.
I have spent the last week or so putting some vague finishing touches on it so that I can give it to said friend to test for me. However after working perfectly fine for me for the duration of the construction and also working fine on a couple of computers I installed and tested it on, upon giving it to my friend I find that (after installing) as soon as he opens up any form which relies on database data it spits out an error akin to the following:
Exception Text:
System.Data.SqlClient.SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
[CODE]...
Loaded Assemblies:
Assembly Version: 2.0.0.0
Win32 Version: 2.0.50727.4918 (NetFXspW7.050727-4900)
CodeBase: file:/Q:/Windows/Microsoft.NET/Framework/v2.0.50727/mscorlib.dll
[CODE]...
I have used a combination of LINQ and SQL statements to query and and update the database, with LINQ for querying and SQL for the updating, due to this most of the database communication is done through a LINQ to SQL datacontext using the pre-generated connection string in my app.config file: <add name="FFL.My.MySettings.FFLv2ConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\FFLv2.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />
The only other time a connection string for the database is used is in an SQL execution function which uses the following: Dim connectionString As String = "Data Source=.\SQLEXPRESS;AttachDbFilename='" + Application.StartupPath + "\FFLv2.mdf';Integrated Security=True;User Instance=True"
The textfiles are also referred to using the 'Application.StartupPath + "folders/filename"' method
As for other details; I started this program on vb 2008 express but upon finding that the express version didn't have much in the manner of deployment facilities, downloaded a 90 day trial of visual studio 2008 pro to deploy the program as an msi install file. Operating system wise, I started the project on XP before converting over to Vista home premium + latest service pack (I think) which is what I've finished it on and am using currently, the 2 computers I successfully installed it on were both running XP SP3 and my friend runs a dualboot of Windows 7 and Vista (not sure what edition), he's tried it on both to no avail.
And for reference; to the above code/error, the database is called FFLv2.mdf and the project FFL.
The pre-requisites for my program (as highlighted by vb) are as follows:
.Net Framework 3.5 SP1
Windows installer 4.5
SQL Server 2008 express edition
I've tried changing the connection strings to specify a specific filepath, but that didn't help.

Sql - Copying A Table From One Database Into A Database On A Different Connection (ADO.NET)
Jun 17, 2011I am trying to copy a table in a database into another database on another connection in VB.NET, using OleDb. If they were on the same connection I would just use SELECT INTO, but they are not. I have two different OleDbConnection and cannot see an easy way to do this.
Right now I am attempting to just copy the database into a DataTable using an OleDbDataAdapter, and then loop through the DataTable and insert every record into the target database one at a time. This obviously takes a ton of time for the large DB I could potentially be dealing with, and I have to deal with escaping strings, null values, etc.
edit - just to make this more clear: I have two OleDbConnection objects, one is linked directly to a local .mdb file on my computer (JET). The other is linked to a database on our servers (SQLOLEDB). I am wanting to do this:
"SELECT * FROM fromDB INTO toDB"
But I can't because fromDB and toDB are on different connections, and the OleDbCommand object is only attached to one. The only way I can see how to do this is to connect to fromDB, copy it into a DataTable, connect to toDB, and copy all of the data in the DataTable row by row into toDB. I was wondering if there is an easier way to do this.
