How to inset data into ms access database in vb 2008
View 2 RepliesI have been posting almost 4 questions now where I have received 2 answers being solved. These are simple questions which any one familar with VB.Net can solve easily. Please understand, I'm a newbie to VB.Net.
Now my next issue is; I have a a form which has text boxes from where the user has to enter the data for the MS Access backend. I am getting the error as INSERT SYNTAX Error when entering the data and clicking the Save button. What is wrong with my insert statemnet below which is at the click even of the Save button?I desperately need to get this application working.

I have two relational tables: the Profiles table which contains 3 kinds of user roles (Manager, Developer, Common User) and the Users table which contains information about the user and their roles ID (Profile_ID field) in the Access 2010 database.
I created a Webform in ASP.NET which should simply register users, asking for their names, selecting their roles in a dropdown list and inserting it all in the Access database. As in the following code:
Dim cs As String = ConfigurationManager.ConnectionStrings("Access 2010").ConnectionString
Dim cn As New OleDbConnection(cs)
[Code].....
It happens that I can't insert in the database because they have a relationship between each other, it gives me an error. Actually, I just need to insert data in the Users table 'cause the roles are fixed. How can I do it?
EDIT
The error I get is You can not add or change records, it is necessary that they have a related record in table 'Profiles'.
I was working through Beth Massi's article, "Using TableAdapters to Insert Related Data into an MS Access Database" here: http:blogs.msdn.co...s-database.aspx
And I configured the TableAdapter exactly as shown by Beth, yet I am getting an error here:
Me.OrderDetailsTableAdapter.Update(newOrderDetailsRow) The Error says: "You must enter a value in the 'OrderDetails.CustomerID' field."
I am using this code for inserting a related record:
Namespace MyDataSetTableAdapters
Public Class AccessIDHelper
'<summary>
[Code].....
I am not able to insert and move on as I am getting the error marked above.
What could be possibly wrong with the above code and why is this giving an error ?
when i insert a new row/record it currently inserts it at the bottom of all existing rows, is it possible to have it insert at a specific row/place? For example alphabetically base don items in column 2.

I am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?

My main problem is that if a build the program and run it outside VS then update never being saved. How can i solve this. I tried using "commit"(maybe totaly wrong) but that didnt work.
I have a VB 2010 program with a single-table Access Database.I have selected the option to copy the Access Database to the output directory.When doing so, the program copies the original database to the inDebug folder.I want the original (NOT the copy) to be modified when the program is being tested.Also, when I attempted to publish the program and run it to test, I got an error which was sourced to be a temporary file (which was the database) that was missing.I think this is a reaction from the "Copy Always" option.
View 1 RepliesVB 2010 Express + MS Access 2003
today I successfully configured an interface to work with a test database I created in MS Access 2003. The database consists of only 8 records with 10 fields.
I used the basic built-ins with VB 2010 to build the interface in a simple form which shows only 6 of the 10 fields. It all seems to work well, that is the connection string built correctly, and I can run the program and view the individual records. My trouble is that when it goes to the 1st record it's actually the 3rd record in the database. And when I go to the last record it's actually the 2nd record in the database and the next to the last record is actually the first record in the database.
why the program seems to start at the 3 record and shifts the first two records to the end. All the records show up, it's just that they are somewhat out of order.
Everytiem I try to access data, like herejust to view it, or edit the table schema or something, the data resets
