Adding Records To Database - Displays IDs Respectively?
Dec 17, 2011
I'm trying to add a record through access. Below is my code. My problem is that when I add a new record, it adds to the database fine, and goes back to the first record like it should, but when I then scroll through using the BtnNext (button), it replaces the last record with the first record for some reason. This is the UI of it [URL]. A bit of further explanation, I'll have 3 records, IDs 1,2,3 respectively. I go to add another (with its ID as 4). When it's added, the program displays ID 1 as it should. It then goes 2 then 3, but instead of 4 as the next one, it displays 1 again. So 1231.
Here's the

I have been trying for a month to get a row added to an Access database and can not do it. I have the databindings all set and can select different records, but can not add a new one. I have tried BindingSource.AddNew.row() but can't figure out how to add data to the new row, nor does it show in the database.
I have tried
Dim ds As New myDataSet '<---Change this to the dataset name on your form
Dim dr As DataRow
dr = ds.Tables("Students").NewRow
[Code].....
But that doesn't do anything at all. No data added, no errors. I have tried updating a datagrid to be told it can't be updated when bound. I look on google and nothing seems to relate to adding data to an access database when bound to the project through the datasource wizard.

I have the following code which I hoped added a row to my DataGridView and also a record to my database. It does the first part, but not the second.
Dim row As DataRow = Me.CCLogDataSet.tblLog.NewRow()
row("cc_log_contract") = Me.txt_Log_Add_Contract.Text
row("cc_log_registration") = Me.mtb_Log_Add_Registration.Text.ToUpper()
row("cc_log_milage") = Me.txt_Log_Add_Milage.Text
[Code] .....
It seems to be storing the data in memory? As the data in the DataGridView is persistant, even after a Relaunch of the application. However, why I query the database, there are no records in it.

I have records in my datagridview (from database(ms sql server 2008 r2)). What i want to do is to insert the records selected by my datagridview checkboxcolumn and IF POSSIBLE automatically delete a record if the records to be inserted are equal to the records inside the database. (Hoping you got what I want to say.) For example. I have an A,B,C(child) that is under XXX(parent) in my database and I'll be inserting the A,B(child) again but it will be under YYY(parent). The old record in XXX will be deleted except C. I just want a possible DELETE STATEMENT These are what I've done so Far :
Insertion of record to database
Try
connectionString = "Data Source=***;"
sql_connection = New SqlConnection(connectionString)

I have used this form to add new records on my database(ms access) in my database I have a column name 'ID' which is my primary key 'ID' is set as auto number. Now I am having a trouble on creating my update and delete button it's always saying "cannot be delete/update"
Here's my code on add, update and delete
Public Sub SaveRecord()
Try
Dim dbConn As OleDbConnection
Dim dbInsert As New OleDbCommand
Dim str1, str2, str3, str4, str5, str6, str7, str8, str9 As String
[Code] .....
Note my add is working perfectly fine. I just can find the error on my delete and update. Also I have used this to view it to my datagrid I don't know if its the right thing but it's working fine too.
'declared dbpath globally'
Dim dbPath As String = "Provider=Microsoft.Jet.Oledb.4.0; Data Source=../VG.mdb;Persist Security Info=False"
[Code] .....
Another thing is how to code each textbox and combobox to bind it to my records so that when I click on the datagridview each column will be distributed on each respective textbox.

I am not able to add records in an Access 2007 database using VB 2010 Express Edition. I have read other posts and followed them but still I am not sucessful. I have the connection to the access database as MS Access Database, therefore it has the OLEDB connection (not the Jet 4.0). I am using the project instance in binding the text boxes to the fieldnames in the Access database. Did I miss something? I am also using Windows Vista Ultimate.

The apostrophe is used to separate data when adding records to an Access Database data table using the "INSERT INTO" SQL statement. Having apostrophes in the data really screws things up with this new software. Is there a simple workaround? Is it possible to specify a different character? Is it possible to add data without using SQL Statements? I also noticed that the new OleDbDataAdapter Add Method generates the same SQL Error because it apparently creates an "INSERT INTO" SQL Statement.gh

How can I design a datagrid that displays records and when one record is double-clicked, you can edit that record or when the datagrid record is double-clicked you can view the past history of that particular record in detail?
If you can view the "chart of accounts" in QuickBooks, then you will understand what I mean.

Pretty basic problem here. Nothing shows up in my listbox at runtime when I add these labels. Dim lblPerson As Label = New Label() lblPerson.Name = "Person" & Master.People.Count + 1 I even tried overriding the ToString() function of the label class as to return Me.Name:

I have some combo boxes which displays one column of one database, and I want to trigger a query to it every time the CBox is changed, but as soon as the dialog with the cboxes opens, triggers itself..
Private Sub cbProd2_SelectedIndexChanged(sender As System.Object, e As System.EventArgs) Handles cbProd2.SelectedIndexChanged
'MsgBox("Changed")
txtQtd1.Text = "2"
End Sub
[Code]...
To test it I used the MsgBox and everytime the form opens it triggers the Msgbox 3 times each combobox.
I tried with SelectecIndexChanged and SelectedValueChanged but none of them worked good (I tried both isolated, one at time)

I have written a program that queries an sql database displays it in a detailed listview, no problems so far. The only problem I am running in to is when I got to print the listview. When I do a regular printdocument.print() It prints out the listview exactly how I have it set up to do so. Which is a title , then column headers, next comes the listview, and then a total of some the columns. When I do a printpreview everything looks great. When I click the print button within the printpreviewdialog only the Title, Column headers, and the totals print. [code]

Processing an XML file with LINQ to add records into a table in a SQL Server database via a data context. As we are adding records we need to assign the parents in various other tables. Most of the time we can find the existing parent and use it but sometimes we will need to create a new parent.Thought we could do this like this:
Dim defaultPub As publication
defaultPub = New publication With {.name = e..Value}
Dim pub = _Data.publications.Where(Function(s) s.name =

I am trying to add a player registration form to a textfile. And i have a few problems.One of these is that when adding to the textfile, it isnt recognising the selected value in a checkbox (checkbox is used to distinguish between a goalkeeper and an outfield player). Can you tell me what should I be writing to make this happen, - "chkGoalkeeper.??? = "" "

I have an application I am creating that displays pump information based on customers in a database. I am using VB2008 .NET3.5.I have a combobox that has a selection for a unit of measure. What I want to happen is when that is changes the labels that have a unit of measure change to reflect the change. There are 15 labels total that need to be changed and all there names are the only ones in the project that start with a X if that helps at all.
I would like to avoid creating a bunch of labels and changing the visible property and just change the text value of each one. I have just started learning VB.NET

I was asked to create a program that inserts records into one parent table and multiple child tables. My question is, how do I know what the PK is for the parent table, so that I may add it as a FK in the child? The PK for the parent is an auto number. As I stated in my title, I'm using VB.net, mySQL, through an ODBC connection. I have to do this through the code and cannot use stored procedures.
my transaction looks like this:
Dim cmdText As String = "INSERT INTO candidate(first_name, last_name, phone1, phone2, email1, city, " _
& " state, country, zip,primary_contact_id ) VALUES (?,?, ?, ?,?,?, ?,?,?,?)"
