Dim strConnectie As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & Server.MapPath("~/App_Data/nieuwsbrief.mdb")
Dim Connectie As New OleDbConnection(strConnectie)
Try
Connectie.Open()
Dim strSQL As String = "INSERT INTO TBL_Subscribers(Email, SubscribeDate, ActivateDate, UnsubscribeDate) VALUES (@Email, @SubscribeDate, @ActivateDate, @UnsubscribeDate)"
Dim command As New OleDbCommand(strSQL, Connectie)
command.Parameters.AddWithValue("@Email", Emailadres.Text)
command.Parameters.AddWithValue("@SubscribeDate", DateTime.Now)
command.ExecuteNonQuery()
Connectie.Close()
Response.Write("inserted")
Catch ex As Exception
MsgBox(ex.Message.ToString, MsgBoxStyle.Exclamation, "BCT")
End Try
End Sub

I've a function named fillgrid() which fills the grid with data.This function works correctly on pageload,but after inserting into database i've called this function again, which is not getting executed.This issue happens only in real time server not in my local system,I'm not getting any error and i cannot recognize why fillgrid() function is not getting called??I've used update panel.This is the code for insert function which inserts over 500records.
DataTable dtMob = new DataTable();
dtMob = dtMobilizn.Copy();
DataSet dsMobilizn=new DataSet("dsMobilization");

I need to check for duplicate records before inserting them into the SQL database.Thus I have the following codes:
For count = 0 To GridView1.Rows.Count
If (GridView1.Rows(count).DataItem("Student Name").Equals(dtDataTable.Rows(count).Item("Student ID"))) Then
lblMsg.Text = "Records Existed"
End If
but there are error message. "Object variable or With block variable not set."

I have a web portal designed in ASP.NET in which we ask customers to enter the data. On the click of submit button all i have done is, just read the data and called a stored procedure which inserts that into a table. There seems to be a problem in SQL Server 2005 while inserting the data from multiple computers at the same time. We have tested in our lab with three computers, result is that we get the data inserted successfully in only one machine and on the other two machines we get error on page. I have used transactions in the stored procedure and also tried setting the isolation levels to READ_UNCOMMITTED, SERIALIZABLE and SNAPSHOT. Nothing seems to work properly.

On a website I'm building user's can subscribe to newsletters by entering their email address into a form and submitting. This will then add them to a 'Newsletter_Subscribers' table in the database.
Users can also sign-up to the website by entering their username/password/email details. They also have the option of subscribing to the newsletter. If they choose to do this then their email address is added to the 'Newsletter_Subscribers' table.
However, I wish to make the data more consistent rather than storing the email address into two different unrelated tables in the database.
Has anyone tackled this issue before, and what is the best way to go about storing this information?
One idea I had was to have a 'Users' table, a 'Users.Members' table and a 'Users.Subscribers' table. All three would have a relating UserID column, with the email address stored in the 'Users' table but I'm not sure this is the best method as I would also wish to store the Username/Password in the 'Users' table in case we had a 'Users.Advertisers' table for example.

Why am I getting two records inserted into the table, when I'm expecting and needing one? The VB code below is checking whether the HTTP is secure or not, and if it is then execute the SPROC. But for whatever reason, I'm getting two records inserted about 5 seconds apart. Does anyone know why and how to fix? I just need one record.

I have a DetailsView control that accepts two different fields to be populated. I need one of them to be masked so that whilst something can be entered, no-one can see what is actually being keyed?

I have a listview that I automatically generated from a database table, enabling editing and inserting on the listview and the EntityDataSource that runs it.
I started customizing the listview templates so that I didn't have to see some of the fields (they're unnecessary from the standpoint of the form), and have alternately tried removing or hiding the unwanted fields. This pretty much patently results in me not being able to insert new records, although updating seems to work just fine. There are no error messages.
I then tried using InsertParameters in the datasource, but that didn't really help either.
In the codebehind I have an onInserting handler that should fill in some of the hidden/removed fields before the record goes to the database.
I've tried pretty much everything I can think of, and even my colleagues are kind of stumped. Why can't I insert records into this table/listview?

Here's the next instalment of my asp.net data access nightmare!
I've got a listview on my page, and when I run the page it correctly displays the data that it should. However, when I add data into the empty new record and hit the 'Insert' button the page posts back but the record isn't inserted. Annoyingly, I don't get any error!
The listview's datasource has an INSERT command and insert parameters specified. The button seems to be triggering the listview's insert method because the ItemInserting event fires.
With no error message to go on I'm struggling to figure out what the problem is. I have a feeling it's something to do with the makeup of the page. The listview in question is nested within an Accordion control and the listview's data source isn't set until runtime, when it's done in the ItemDataBound event of the Accordion control. As I say, though, it does RETRIEVE data correctly, it's just the inserting that's a problem.
I created a new, blank page with just this listview on it using the same code but not nesting it within any other control and hardcoding the datasource instead of setting it at runtime and that works perfectly, so I'm confident that my INSERT command, insert parameters and so forth are correct.
I've tried to get my listview to break, deliberately leaving out insert parameters and so forth just so it'll give me an error message but it never does! It's as if the insert isn't taking place at all, except that because the ItemInserting even takes place I'm assuming that it is.

I have a form that is doing a simple insert, then a sub insert of a certain drop down selection is made. What i dont get is why the main insert is inserting duplicates and the sub works fine inserting 1 record per text as expected. I click the button 1 time, and when i check the table, there are 2 new records.. As you can see the insert is not wrapped with any conditions, once that is inserted i check if a slection was made and runs the sub insert.
My full code can be found in this post [URL], but here is what i have for my button event.

I've looked all over for this problem but can't find anything that works. I have a details view bound to a database that when a user enters their details and clicks insert it will store the data and then send them to another page. I have tried response.redirect but that does nothing. I am using c# btw.

Using checkboxes, can the row of record(s) be inserted into a database? I am populating a Gridview. Done. A checkbox field has been added, when the user selects one or more rows, a submit button (which is not working) needs to inserting those records into a table. The insert statment will work outside of the page but is not working using the scenario I jut described. Is this task as I have outlined doable?

I am using Linq to SQL. I have a table with a uniqueidentifyer column.
I need to insert 1000 records, each with all the same values except for the uniqueid field.
I know the syntax to insert a single record for example where dc is a DataContext():
[Code]....
Does anyone know how if there is a way, other than looping 1000 times, to tell SQL to insert 1000 records generating different unique ids but assign the constant values to the other columns?

I am trying to sort a DataTable. If I declare a DataView and use the following approach it works perfectly:
Dim dt As DataTable = getData()
Dim dv2 As New DataView(dt)
dv2.Sort = "surname, name"
dt = dv2.ToTable
I wanted to do this without using a DataView though if possible to reduce the impact on resources. I tried the following approach but it doesn't work. I might be writing the code wrong so
Dim dt As DataTable = getData()
dt.DefaultView.Sort = "surname, name"

What is the best method in T-SQL 2008 for extending a table's records with the criteria of 'repeating' all fields but the Primary KEY e.g. Consecutive Date for the previous n Records.
So you have for example 7 records (Easy...2 Fields. Date and nvarchar) with th Date runing from Jan-01 to Jan-07
We want to extend the table by 21 records...so
Record 1,8,15,22 will look identical apart from the DateField.
Record 2,9,16,23 will look identical apart from the DateField. etc...etc..
I have tried a number of methods ...all coming up short....
