My program runs with no errors, but the actual .accdb file does not reflect changes when I make them in the running program. Also when I fill in the text boxes and click the "Add New Item" Button, the "ID" text box displays a -1. "ID" is the primary key in my Access Database.

View 3 RepliesI'm working on a simple data logging program, and I have little to no database experience. I wrote a little VB forms app to log the data to ms access and then graph the data, but I'm having trouble with adding records to the database. First, I created a simple one table database in access. Then, I added the database to the project as a data source, and gave it a data set using the wizard. Right now my code looks like this:

There are no problems during build or run time, but I do not see changes to database after the program runs.
so now i know i have to use begintransaction to insert records into Access. i've searched for information and it seems that i have to implement Ole.DB and SQL in order for begintransaction to work. My question is, currently i didn't implement any Ole.DB or SQL codes to connect my Access database to Visual Basic.

View 4 RepliesI typically dont use a dataset in a case of new data insertion to the database. But then again, I will run in a problem the weather the inserting data already exsit in the database. Therefore i need to perform a search first. However, if i follow this it will take slow down the application (if the table has 1 million records). One way i could optmimize this is to load the whole table in to a dataset then the application doesnt have to go to a back end trip nwo it can search inthe dataset. Is this the standard way for inserting records?

I have a web portal designed in ASP.NET in which we ask customers to enter the data. On the click of submit button all i have done is, just read the data and called a stored procedure which inserts that into a table. There seems to be a problem in SQL Server 2005 while inserting the data from multiple computers at the same time. We have tested in our lab with three computers, result is that we get the data inserted successfully in only one machine and on the other two machines we get error on page. I have used transactions in the stored procedure and also tried setting the isolation levels to READ_UNCOMMITTED, SERIALIZABLE and SNAPSHOT. Nothing seems to work properly.

I have a deployed desktop application which uses an Access Database. I have a need to update the databases which are in the field by adding a few extra fields to some tables to support new functionality. Thedatabases is password protected.
The process I am following is to ship a new empty database which contains the new fields (these fields are set to not require entry, accept nulls and they are not indexed) and then add functionality to the application which selects the data from each table in the current deployed DB and inserts it into the same table new template database. Then I kill the original db, rename the new template to be the file used by the application.
I am using OLEDB to communicate with the database and have tried using an 'INSERT INTO' but cannot get the syntax right - I used this example[URL]..but it throws and invalid argument when I try to supply a database password

Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?
For some reason my code is executing the INSERT query twice and putting duplicate records in my table. If I put a primary key on one of the fields I get a runtime error and it complains about the fact it can't add the record twice.The part of the code that INSERTs is near the bottom, bolded and italicized. I put the entire IF statement of code incase my logic is wrong.This is what's being executed when a user clicks a button
