Auto-Numbering Primary Key In Access 2007 Database?
Aug 3, 2010
When I add a new row to an access database, I would like the primary key to be automatically incremented and entered. I've got this to work using a sql database, but it doesn't work with access for some reason. The following code works if I give the code a value for "@key" which is my primary key column. If I leave it out I get the error "Number of query values and destination fields are not the same". I don't want to have to supply the primary key, I want it to generate automatically.
[Code]...
In the database the primary key is type "AutoNumber". Does anyone know what I'm doing wrong?

I conected my access database with the form and I need the code to count how much entries are in the database and increase that number by one, and then to write that number in one textbox so that when I press save in the form the entry would have that numbar as id.

I am using the vb 2005 to create an application and I created a database from the vb by adding a new Item (Database). I want to know how can I make the id which is a number, to take an auto number and not to have to enter it with my insert statement. I know in oracle I use a sequence and in access I use Auto Number as a type for the field, I want something like this here.

I'm using vb2005express for forms (front-end) and ms access database. I have a form with a master-detail setup. The problem I'm having is that when I set the primary key column to autonumber, I don't get the pk value generated in ms access database into my master datatable in forms when a new record is created. Then I tried setting the AutoIncreament to True in the pk column of the datatable in my dataset (forms). This generates a number in my pk column but its not the number generated in the database (since I think because the pk column is still set to AutoNumber). So I change the field property of my pk to Number in the access database and on my dataset (forms), i still have AutoIncrement to True.
This works okay since what it seems to be doing is getting the max value for the pk column when the datatable is filled upon form load. The problem now is that I normally don't do tableadapter.fill(datatable) at form load since I think there would be a performance issue if record counts around millions. What happens now is that when I create a new record, the pk generated is still 1 which will cause duplicate violation when saving to database. I'm not quite familiar with access features but in oracle, what I do is I create a sequence in database then I create a function that gets the next value of the sequence. Then at form load I set the datatable.column.default_value = get_sequence. How do I do this in ms access?

i am wondering if it is possible to get the source code for the following:
1. use vb.net code to set on/off primary key when connected to Access database
2. update a particular data.
for e.g: hostname: AES-19 *use source code to check data in Microsoft Access database
if hostname is new, insert into Access. if hostname already exist, update into Access
*so that i will not have duplicate data in Access.

I have managed to successfully create a logon page and have created a form to insert data into one of my tables using text boxes and a "Save" button, however the first field in the table is the named "CustomerID" and is set to Autonumber, this is the primary key of the table. If I enter a record into the table in Access it automatically enters the next valid ID however when I can't seem to make this happen when entering data via my VB form!

I am having an issue with my program that I hope you can help with. I have integrated my program to work with Outlook and I have installed the 2003 Primary Interop Assemblies on the client computer and it works fine (i.e. opens Outlook Email and attaches a file from my program). Well, we have many computers here that run Office 2007, so I installed the 2007 PIA on their computer and it doesnt work. It doesnt tell you anything in the error when the update download fails, just "You need to contact your system administrator". Is there anything else I need to do to get it to work with computers running Office 2007 - any references I need to add, or properties needing changed?
I know the isnt any issue with the server, connectivity, or anything like that because it works just fine on computers without Office 2007.

I am using VB 2008, then I noticed that with the Provider.Oledb.12.ACE = database.accdb whatever connection string uses the bin/debug/database.accdb file when I connect my program with a database. Suddenly, a database with the same name appeared on the lets say "WindowsApplication1" folder. Then whenever I try to debug/run, it throws an error saying that it was unable to copy the database from the "WindowsApplication1" folder to the debug folder even though VB 2008 reads through the database from the bin/debug folder. As a result, after I input values when I debug, it resets because VB 2008 copies the database from the "WindowsApplication1" folder.

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.

I just installed a VB application developed using VS 2008. I installed the application on a Windows 7 machine. The application uses a MS Access 2007 database.When I run the application, an exception gets raised:The "Microsoft.ACE.OLEDB.12.0" provider is not registered on the local machine.But I don't seem to have this problem on a Windows 98 machine.

I have an application that uses an *.accdb file as the back-end database. Connecting to and retrieving data from the access file is not an issue and is working quite well. However, as a precaution, I have the application first check to make sure the database file exists in the application's folder while it loads up. As a convenience, if the database file is not found, then the application creates a new (structured, yet empty) database. The creation of the actual *.accdb file and the creation of the tables is complete and is also working well.
