Add A Record To An Access DB?
May 26, 2010
I had my students connect to a MS Access DB (2002) and used the datagrid to display the data and that works just fine. Theproperties are set to allow adding of records, however when we add a record it seems to accept the record, but if you check the table its not there./ No error or any indication there is a problem, the record is simply not there. You can add 10 to the datagrid and they will appear in the data grid but not in the table an of course if you closethe app & reopen it the records are gone. This used to work just fine, by the way the same thing happens when you use the Binding Navigator so I don't think its VB, I'm guseeing its Access?

I have a access database with these columns. USER_ID,COUNT,TIMES
Let say the current record is this:
USER_ID,COUNT,TIMES
STEVE20,24,1.5
Now I want to updated the current count record and times, but before updating I want the old record to be added to the new record. What should be my query?

I have an Access 2007 DB With 3 Tables I fill a form with information from 2 of the tables which works fine I then want to add a row to the third table with the information obtained from the form.(I know this may seem like duplicating data but there is a reason for doing this that I can explain if needed) This is where I am having the problem. I have tried several approaches with no success.The following code works fine I get no errors and it even says it added a new record but it does not. when I look at my access table there are no changes.Why can I get info from the DB but not Write back(yes I have the properties set to "update if newer"[code]...

Hi, as part of a computing project I am writing a program to add, edit and delete data from an access database.
I have successfully written code to edit data but when adding a row to the dataset I run into a problem.
This is the code in my button which adds a new record.
Dim cb As New OleDb.OleDbCommandBuilder(da)
Dim NewRow As DataRow
NewRow = ds.Tables("CandidateID").NewRow

Im having problems getting data out of the databse and checking a checkbox if the records are there. I have two Records in my access database:
IDItemIDLocationIDInStock
1544MainWarehouse900
2544NewLocation100
3544StrongRoom200
WHat i have done is Create a SQL string that takes the ID 544 and searches through database. If a match is found the the same as the LOCATION name on another Table then it takes the LOCATIONID (it will be the ID, but not at the moment) and puts it into a listview along with its IN STOCK.THe location Table looks like so:
IDLocationName
3MainWarehouse
4StrongRoom
[code]....
Running through this code. The system checks the "NewLocation" checkbox ONLY!

I have 2 tables in my database (SITES and RECORDERS) SITES has only 2 fields (SiteID and SiteName)
RECORDERS has SiteID as a foreign key.
The primary key of RECORDERS is two fields, SiteID and RecorderID .I don't want to use a DataGridView for editing. I like the Details view and have dragged the fields to my form (using the Data Wizard). It adds the BindingNavigator to the top of the form and I'm able to go through each record of the RECORDERS table successfully.
What I am wanting to do is somehow select (through a ComboBox or ListBox)a SiteID and RecorderID (which will return one row) and have it load those fields in the controls just like it does with the BindingNavigator.I want to maintain bound controls to make the Addition and Deletion of records easier.
The reason for this is navigating with the BindingNavigator one at a time is quite cumbersome if I need to access a record near the end or middle.

Any way that I can set the value of a particular field (let's say a name) on a particular record without having to have the data presented on the forum? Syntax would be along the lines of "Go record "12" and set "Callum Kerr" on field #name"?

first of all here is the code that populates the fields when the user logs in. This code is correct and works fine.
Dim passwordrow() As Data.DataRow
passwordrow = MyDBDataSet.Tables("Customer").Select("Username = '" & txtusername.Text & "'")
'This try statement checks to see if a row has successfully been found

I'm at another wall in my project. I've been trying to get it to add a new record to a table but I got a message that said "Object reference not set to an instance of an object" but I have no clue where the error is popping up. I am also unsure of whether the coding for adding a record will actually work on not.Here is the code for the form with the bits subs that I'm sure aren't the problem removed (as they have no relevance to adding a record);

We're trying to work out some code for saving from a textbox to a database field without using DataGridViiew. We have it working using the automated controls that Visual Studio gives us, but if we have a form with text boxes, can we make it so that, on a button click, it dumps that stuff into a field in a table?

I just want to add a value from a textbox/variable and save it as a new record in a MS Access Database after a button click.
I've set up the database, set up the tables required.
From what I gather, I need to first link declare 'Imports System.Data' outside all the code. And also define a variable as a connection (Dim con As New OleDb.OleDbConnection) then access the database with "con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = PathName").
What else do I need to include?
