Access Database Connection And Work With It Using ADO Objects?

Oct 11, 2009

I opened vs 2008 and used the server explorer for the first time to create a connection to my SQL 2005 db. The solution explorer pulled in all the tables, the database diagram etc. My question is how do I access that database connection and work with it using ADO objects? Do I need a reference to ADO?

Close Connection To Access Database?

Dec 23, 2009

I created a connection to a Microsoft Access database by using the wizard. Now in the server connections I see my data connection to the db. I'm trying to create a method to compact the database, so I used JRO to do it. To do it however, an exclusive access is required, and when I try to call the method I get an exception.

Database Access After Closing A Connection?

Feb 17, 2010

I'm writing a Windows form application in VS 2008. In the application I need to move among several SQL express databases (.mdf). I'm using the following commands to change the connection:

Me.MyTableAdapter.Connection.Close()
Me. MyTableAdapter.Connection.ConnectionString = "NewString"
Me. MyTableAdapter.Connection.Open()

I can see the form is showing data from the 2nd database. However, When I tried copying the 1st database (for a Save as function I'd like to implement), I got a system error saying "Cannot copy MdfFile: It is being used by another person or program.". Actually, I found all the visited databases were "being used" untill I closed my application. How do I break the connection completely?

Run Computer But Program Does Not Work As It Cannot Access Database

Mar 18, 2012

I made a program that i want to run on computers at school and it utalizes a MySQL database. When i try to run it the program does not work as it cannot access the database. I open the code up on my computer at school and it has errors saying ti does nto recognize the MySQL code as it does not have it in its .Net library. So i try to download it into the library but that does not work. So my question is, will programs using any kind of database not work unless the user installs the needed add on, weather it be a .Net library add on or a java add on for MySQL? That cant be right it.

Dao Connection To Access 2007 Database With Attachment Field

Oct 6, 2011

I am working on an asp.net project in VS2010 using vb.NET (not VBA) designing an interface to allow a user to upload a file to an access 2007 table attachment field. My understanding is that in order to interface with a table with an attachment field you
must use DAO to connect to the database so that you can expose the attachment field properties. When I try to open the DAO recordset I am getting "COM exception was unhandled by user code" with a message stating "Too few parameters. Expected 3". The error code is -2146825227 and the stacktrace message is "at dao.Database.OpenRecordset(String Name, Object Type, Object Options, Object LockEdit)"

WIndows 7 Won't Run .NET MS Access Database Connection Program, But XP Mode Does?

Mar 16, 2010

I 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?

DB/Reporting :: Access-database Connection Provider (like Dao Or Ado.net) That Works On A 64 Bit Machine?

Jul 8, 2010

I'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

Asp.net - Swapping A Connection String To Access A Test Database For Unit Testing?

Jun 22, 2009

I've set up a test database to begin unit-testing an app that I've recently been added to. It is a 3-tier design (presentation layer, BOL and DAL) and this is my first time writing unit tests. I've decided to start at the BOL and I figure the best way is to swap out the ConnectionString (which has been passed along as a Shared String) with one that points to my new test database. However, I don't wish to change any production code. I simply wish to somehow redirect the app to the test database during unit tests.

Make An Oledb Connection To An Access Database : Invalid Authorization Specification

Sep 15, 2007

I 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?
