Update Access Database With OleDbCommandBuilder?
Oct 7, 2011
I have been working on this for a couple days now, and I am ready to throw my computer through the window.I am still rough around the edges with Visual Studio 2010.When I run the project, it works just as it should. the fields populate with the selected items from the .accdb, and I can navigate just fine up and down the rows. The problem comes when I try to update the info. When I change a value and hit the update button I get the following ERROR: System.Data.OleDb.OleDbException was unhandled Syntax error (missing operator) in query expression '((PID = ?)

I have a field in a 2003 access database named first. I run the data adapter update command, gives me "Syntax error in UPDATE statement." I change the field name to firstName, try the update again, it works. I already have a bunch of programs using the database and using the field "first", do I really have to rename my field, go back and update all my programs to read from firstName instead of first? I really don't want to go that route if I don't have to. (provider=microsoft.jet.oledb.4.0)
*Edit: I meant to specify, I want the answer to use commandbuilder (but it won't work that way).

This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

How can I do that? I already have the code I'm working on but it seems that it doesn't work really fine. I input an id number(unique) on a text box and click the search button. The entries that corresponds to the id number is then displayed on the other text boxes. And then I try to edit one of the entries manually(changing its letters or name) then I click the update button.
Here is now the problem: It really updates the entry but it makes a mirror of the entry with a different id number(maybe automatically generated). So basically the ms access database will now contain the old entry and the updated version of the entry.

I am an experienced VB6 programmer trying to adapt to the vb.net mindset. I am using Visual Basic 8 and I am using Microsoft Access 2003 as my database. I have spent the past 6 hours trying to do something as simple as updating my database for the following event. Everything I find on the net is either using SQL server or bound controls (which I don't think can work here).
I have a login page (gets the data from the database)( which then opens my main form. This works fine. I then have a menu item that allows the user to change his password. After doing all the appropriate validity checks, the program is supposed to save the new password back to the database. This does not work. I have a textbox where the user enters the new password. How do I set up (in code) the appropriate objects to then save the data. The pertinent code is below. I have left off the connection string (cn) as I know it works.

I have a form in vb8 that is set up as follows:
I have a table in my Access database calledUsers that has a name and a password (encrypted).
Using the toolbar I created aBindingSource with a name of UsersBindingSource and a dataSource ofUsers
Using the toolbar I created aDataset called with a Name and a DatasetName called Users_Dataset
Using the toolbar I created atableAdapter called UsersTableAdapter
I added two textboxes on the form and changed theirDatabindings...Text property to the corresponding field in the Database.
How to now update the database when I click Update. What the program needs to do first is encrypt the Password before saving it. I wrote the code in the TextBox2.Lostfocus event to encrypt the data a place it back into the TestBox2 field. The only samples I find on the net refer to DataGridView controls (which work) but I don't want to use them. How can I get the database to accept these changes as well as changes to radio buttons or comboboxes?

I've been perusing some hep forums and some help books but cant seem to get my head wrapped around this. My task is to read data from two text files and then load that data into an existing MS Access 2007 database. So here is what i'm trying to do:
Read data from first text file and for every line of data add data to a DataTable using CarID as my unique field. Read data from second text file and look for existing CarID in DataTable if exists update that row. If it doesnt exist add a new row. once im done push the contents of the DataTable to the database.
What i have so far:
Dim sSQL As String = "SELECT * FROM tblCars"
Dim da As New OleDb.OleDbDataAdapter(sSQL, conn)
Dim ds As New DataSet
[Code].....
In constructing my table i use "SELECT * FROM tblCars" but what if that table has millions of records already. Is that not a waste of resources? Should i be trying something different if i want to update with new records?
Once Im done with the first text file i then go to my next text file. Whats the best approach here: To First look for an existing record based on CarNum or to create a second table and then merge the two at the end?
Finally when the DataTable is done being populated and im pushing it to the database i want to make sure that if records already exist with three primary fields (DriveDate, DCode, and CarNum) that they get updated with new fields and if it doesn't exist then those records get appended. Is that possible with my process?

I have been tasked with writing a program for our yearly reviews. We want all of the information gathered in the form to be submitted to an access database. I have created the form and the database. I can send info to the database but it is put on a new line everytime it is submitted. I would like to check the first column of the table to see if the user login is already there. If it is there I would like to update the information. If it is not there I would like to create a new row. This seems simple, but I can not figure out how to see if the user login is already there.[code]...

I am developing a VB.Net windows application to replace a legacy Access database. I started with the legacy database (.mdb) and made changed to tables (like deleting unused columns) and changing anniversaries from 3 columns (day, month, and year) to DataTime etc recognized the need to import data from the legacy system at the time when the new one goes live and wrote an import dialog to do this. And this is where my problem is. The importer correctly imports the data and writes new tables, but each time I restart the application I have the old data back.
This is the approach I took:
In the load event I fill each tableadapter in the new (target) dataset as follows:
Me.ClientInfoTableAdapter1.Fill(Me.DataSet1.ClientInfo)

how to update records on an existing access database using vb.net with just a textbox and a command button and how a specific record of a field can show up in a label or a textbox
i connected vb.net to my access database by just clicking on "add new data source">>"new connection">>"microsoft access database file" and just continue..tested connection and done.
you can see in the screenshot of my form, by default the left side textboxes are disabled but they're enabled if the user checks the checkboxes and disabled again if unchecked.
assuming that the textbox is already enabled and i want to enter a value in the Brewed Coffee area of the form...for example 5. when i click on my Submit button the value of that particular record in the database will be updated, so in my table the value of the quantity field in Brewed Coffee will be 5.
another thing is that how can i see a particular value on a label or textbox from my database like on the Prices area. in my database if a product's price is 80 then it should show a 80 in the label. the values of the prices from the screesnshot of the form are not the ones on the database xD i just typed them in.
