Delete Data From Access DB After Use

Nov 15, 2011

I was wondering if there is a code i could add to my applicatio that will delete a data entry from a database. I'm designing a voting application as my project and i want a situation where an access code is good for only one entry. i put my code for retrieving the code below.

Is there anything that i can add to the code that will delete the entry that was used to login immediately after authentication?

Private Sub btnCodeEnter_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCodeEnter.Click
Dim connect As String
Dim query As String
Dim dbProvider As String
Dim dbsource As String

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.

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?

Unable To Delete Records From MS Access - OleDbConnection?

Feb 6, 2010

In my application, I open a "Customer Details" form and on confirming I have to delete all records from other 2 tables (Order & OrderDetails) of the database. I am not able to delete records. It somehow stops by on -  ordDetAdap.Update(ordDetDs) . The code is as follows :


There may be N number of Orders and each order may have N number of OrderRedetails. There are rows and also shows proper data in MsgBox, also row.Delete works fine, BUT why does it stop at Update(OrdDetDs) I can't make out. Any idea where am I going wrong.

Also Is their any easy way out to delete all records using just a single statement providing OrderId from OrderDetails table ? As of there are 10 rows of a single order, then For loop will iterate 10 times and delete 10 rows, instead if I can delete all 10 rows at once would be beneficial.

Delete Directory (Skip Access Denied Folders) ?

Jul 22, 2009

I'm fiddling around with a small program that can delete a directory, including its sub-folders and files.This is the code I'm using: (Note-I found it on the net, I didn't code it myself)

Private Sub filedelete(ByVal filename As String)
Dim filesystemobject As Object
filesystemobject = CreateObject("Scripting.filesystemobject")[code]..........

So on click of button '2' the folders are cleaned out, and on click of button '3' they are deleted - it works great.Now the problem is, if any of the folders in the directory 'test' are not accessible to the current user, the program throws the exception 'Access to the path is denied.Is it possible to skip folders that are not accessible, and just ignore them, and delete the ones that are accessible?What code needs to be added to enable this ability?
