Application Which Can Create/update/delete/search Records Using Access Database?

Apr 24, 2010

i have a simple application which can create/update/delete/search records using Access database. If i add a record, save it, then close the application and run it again and search for that record, it appears. However, when i write some code to my application, nothing to do with the search function, and i run the application the record is not found. For example i added a button to clear the textfields, and when i ran the application the records i have added earlier were not found.

Update And Delete Records In Database (3 Tier)

Jan 8, 2010

I have problems with the updating and deleting of records in database. I'm using ObjectDataSource and the GridView to display the results in the database. Below is the codes for the update and delete (in the DAL (data access layer). BTW, I'm doing 3 tier architecture in VB.

'update the records accordingly in the database.
Public Function UpdateBooks(ByVal title As String, ByVal borrowDate As String, ByVal dueDate As String, ByVal NameBorrower As String, ByVal book_id As Integer) As Integer
Dim connectionString As String = My.Settings.dbConnection
[Code] .....

I don't know why, but every time I try to update (by clicking on the update button), every thing is not updated, the page would refresh then the records still remain the same in the GridView. As for delete, when I clicked on the 'delete' button, the record is not deleted, it still remains there.

These are the codes in the (BLL (business logic layer)):
Public Function getUpdateBooks(ByVal title As String, ByVal borrowDate As String, ByVal dueDate As String, ByVal NameBorrower As String, ByVal book_id As Integer) As Integer
Dim ds As Integer = UserDA.UpdateBooks(title, borrowDate, dueDate, NameBorrower, book_id)
Return ds
[Code] .....

Adding Records On Database - Creating Update And Delete Button?

Mar 10, 2012

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()
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.

Cannot Delete New Records In Access Database

Feb 17, 2008

I'm creating an application that adds and deletes records from a microsoft access database. The language I'm using is VB2008. I am importing the database through a wizard. I can add records and delete records, but I cannot delete a newly added record without closing the form first. When i reopen the form, I can delete the record. Here is how I have my database setup:

'Bind user info to the controls.
AUSERDataSet = New BulldogUsersDataSet
AUSERTableAdapter = New BulldogUsersDataSetTableAdapters.UsersTableAdapter
' Setup the binding source.
AUSERBindingSource = New BindingSource

Database - Delete Records From Ms Access?

Dec 21, 2009

how to do it, but the tutorial is not applicable on the program that I wish to do. The tutorial tells you to add 4 navigation buttons so that you can navigate the database(first, last, back, and forward). Then an update and delete button. But if this is what I will do, it would take 10 years to navigate the database and update a record. Now, what I want to do is just for the user to input a unique ID and click search button(which I have already done). Then the update would be easier. How can I update or delete a record using this method?

How To Update Records On An Existing Access Database

Sep 28, 2009

how to update records on an existing access database using 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 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.

DataTableAdapter.Update Doesn't Insert New Records In The Linked Access Database

May 20, 2010

I am writing an application that does a number of different things with data downloaded from hardware which is monitoring the power used in my home and produced by my PV Solar array. I have run into a roadblock early on, because I cannot seem to get new data into an Access database that I have linked to my application by means of a DataSet. I have checked the DataAdapter's InsertCommand, DeleteCommand, and UpdateCommand definitions (created by the DataSet Wizard), and they seem to make sense, and nothing is throwing exceptions or otherwise making VB complain, but new rows added to the dataset are not being added to the database.

VS 2008 - Delete / Insert Rows And Update Access Database

Jan 5, 2011

I am using this code to Add rows to a SQL database, and it adds the row to the SQL database if column 7 is not null. After it adds the row to the SQL database, it deletes it from the Access Dataset, and updates the Access Database. Sometimes double rows seem to get inserted into the database, so I'm thinking there is an error in my logic somewhere here.

Dim rowcount As Integer = AccessDataSet.AccessTbl.Rows.Count
Dim y As Integer = 0
For x = 0 To rowcount - 1
txtRow = AccessDataSet.AccessTbl(y)
If IsDBNull(txtRow(7)) = False Then
