Update A DataRow Immediately After Inserting It ?

Sep 20, 2011

I have an OleDBDataAdapter which I am using to communicating with an Access database. I have generated a SELECT command with parameters, and used this to generate a DataSet.I have then used the OleDbCommandBuilder to generate the UPDATE and INSERT commands. I can use this successfully to fetch data and then update it.

Next I have created a I have a DataRow using DataSet.Tables.NewRow which I have populated.I have then used my DataAdapter to insert this record.This works just find. I would like to now update this DataRow.Can I refresh this DataRow so that it populates the fields such as the autonumber field and the automatically populated timestamp? I could select it again but I don't know the autonumber. Is there not some way that I can get the existing DataRow to synchronise with the new row?

Update Ms Access Database Via VB

Dec 6, 2009

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.

DB/Reporting :: Access Update Error?

Oct 29, 2009

Well here I am again, could really use some expert eyes on this. I've got an update statement for access 2007 and when I run it it's giving me a "No value given for one or more required parameters." error. I've spent at least 2 hours on this now and searched all over the place and none of the suggestions I found are fixing it. I've got an insert statement to the same table that works fine, I took this same syntax for the update statement from another project where it was working perfectly. I've verified the spelling of the table and column names, As best as I can tell there are no reserved keywords being used and I've eliminated any spacing from the names. I've even tried updating a single row with no variables, just like for like data directly from the table and it still throws the error.

Code:
Dim DAEdit As New OleDbDataAdapter
Dim update As New OleDbCommand("UPDATE ActiveContracts " & _

At Wits End Trying To Update An Access Database In VB8

Apr 11, 2010

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.

Cannot Get DataSet To Update Access Database?

Apr 16, 2010

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?
