VS 2008 Error Connecting To Access DB?
Nov 30, 2009
When I try to connect to an access database I get this error: "The Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine."It comes up when I try to debug, da.Fill(ds) becomes highlighted and an arrow with that error comes up.I dont understand how its not registered on the machine, when I check the connection to my access database in the visual environment it says its successfully.

Microsoft Access 2007 A Students.mdb database file Visual Basic 2008 Express Edition. I was informed that one can connect to Access files with ease from the Express Edition and most of the tutorials on the internet also show this however I am encountering a problem.
I open Visual Basic 2008 Express Edition Start a new project, with a form, and then click on the Data window, and add new data sources from the Data menu.
I click on database. The problem starts with the data connection. I click New Connection Change the Data Source from Microsoft SQL Server Compact 3.5 to Microsoft Access Database File and instead of then leading back to the other window (as happens on the tutorials for me to browse for the mdb file). Another window pops up asking me to Add a Connection.
It has the data source listed as Access and asks for a Connection String under the misc section. I type in
CODE:
When I click on Ok I get this error: Format of the initialization string does not conform to specification starting at index 0.
The Test connection button works and says connection success whether the Connection String field is empty or not but when I click OK it still gives me the same error. So I can't leave it blank either
So basically I can't connect to the Access database since I can't change the connection type and it won't just let me browse and add the file anyway.

I'm using an MS Access database which has password (database password, not a workgroup or smth). I'm using 13 characters - with no special signs- only letters. When I try to open the DB from access it works fine, but when I try to run my Windows Form application from Visual Studio Connection String, I get a message that "Not a valid password".

First timer here, I love the site!
Running:
- VS 2008
- Sharepoint 3.0
- Access 2007
- Windows Vista (The machine I'm developing it from)
History: (Do excuse me if I don't reference different methods I've taken so far correctly, I'm still learning!) I am building some search software for a law firm that I work for in Australia. It's all coming along really well, but I seem to have hit a snag getting data out of sharepoint lists and into my project!
I first attempted to add a web reference to sharepoint and after a while was able to pull in all of the data from the lists, fantastic!(OR NOT!). The issue then was when I attempted to load it up into an array using XMLNodes, whilst it loaded up fine and I could see all the data, if there was a null value in one of the columns, it wouldn't pull that null value across, therefore, I couldn't really use the data...

I have a VB.net program connecting to an Access database. I use ADODB as connection (force of habit, I suppose). The program runs fine on all my machines, but on some of the client machines I get an error on the connection to Access. It is intermittent (sometimes runs without any problems) and happens at different places in the code, but always at the connection with the database. The program connects and closes connections quite a few times during a calculation.

just a few questions. I have read through a of tutorials and snippets on access database.Connecting, updating, inserting, deleting, etc. My main question is this, I have not yet coded the connection to a database using code such as you all. I have always used the wizard to create my connection, table and view this also add the database to the project. Is it better to code the connection, or use the wizard? I have just started creating a program to feed company keep track of there inventory, right now I have 2 tables (feed, misc) both table contain the same things (code, description, price, and quantity). Any way I am getting off the subject, Write the code to connect to the database or use the wizard?

So I downloaded the VB 2008 Express edition. My information is stored in a Access 2000 Database I'll call db1.mdb..After I connect I can't seem to run queries, it says that I don't have read permissions. I think this is because my string doesn't contain my workgroup information. I'll just explain my steps.In the Database Explorer I added a Database connection. I chose Microsoft Access Database File, with the Data Provider being
".Net Framework Data Provider for OLE DB"..I browse to my db1.mdb file. The file itself has no password to it. So I test connection and it is fine. Unfortunately when I try to run a query from the Database Explorer, it says I don't have read permissions.When I normally log into Access I fill in workgroup login info. My connection string doesn't have this information so I'm wondering if that could be the cause.[code]How would I add the workgroup login/password to the conenction string ad is this the possible cause?

I want to connect to a Access Database I've tried to do it though Data Binding and that doesn't seem to be working so I'm going to have to do this through Code... every book I have tells you how to do it with SQL Server but can't find a example for Access that doesn't involve just using the databinding tool. Writing the queries isn't a issue it's just connecting to the database and then putting that data into a couple of text boxes. Lets say the database is called TestData and the table is ClientInfo and we want to put Date, First, Last into txtBox 1, 2 and 3 respectively when the form loads.

I'm trying to connect to a access 2007 database with VB 9 and am having some problems.
I went to Data and then selected add new datasource.
Then I clicked on database and selected Next.
I click on new connection, change the datasource to access database file and then click ok.
It doesn't give me a browser box so I can choose where my access database file is. All it shows me is a connection string label and a text box to the right of it. I tried entering the full path to my accdb file in that connection string box and also just the name of the file itself since it's in the same directory but get the error message "format of the initialization string does not conform to specification starting at index 0."
Also, when I click on test connection, it always says succeeded even though no database has been selected.

This is my function:
Public Function DBConnection(ByVal path As String)
' This function makes the database connection and returns the object
' to reference it.
[code]....
As you can see, I want to initialize a database connection and return it so I can use it in my forms. This function is in a module and my variables are as follows:
Public cn As OleDbConnection
Public cmd As OleDbCommand
Public dr As OleDbDataReader
But I'm not sure how I can use this in my forms, do I just call the function DBConnection and then proceed with my SQL statements? Also, I need some opinions. My application relies on a MS Access database. Is it better to initialize the connection on Form_Load and then close the connection when the user closes the program, or open and close the connections as the queries are run? I'm planning to use some database queries on multiple forms hence the reason I was putting it into a module, but I'm not 100% on how I should proceed with this.
