I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts

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.
having trouble adding records to an existing dataset, I tried the following code but it made a new connection which I don't want:
Dim inc As Integer
Dim con As New OleDb.OleDbConnection
Dim da As OleDb.OleDbDataAdapter
Dim sql As String
[code].....
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'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.

View 1 RepliesProcessing 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:

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.??? = "" "

View 3 RepliesI 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 (?,?, ?, ?,?,?, ?,?,?,?)"

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 :

I know that when I add a record to a table through a binding source using a binding navigator - it completely handles the IDENTITY PK (it's bound to a textbox and you can see it immediately).
Now I'm trying to do this differently in another part of the program - here I only have a BINDING SOURCE - that's bound to a DATAGRIDVIEW.
I put a new record into the DGV like this

View 3 RepliesI'm, using a SQL Server table in a DataGridView and I'm having trouble adding records. I'm new to vb.net but used vb6 for a lot of years so the transition is a little difficult. For now I'm just trying to add a record using a button click but the record key which is setup as integer and to automatically increment by 1 shows as -1 after the record is created. While the data does show in the grid it is never actually posted in the table. Once created I want to select the record just entered.
Here's what I have:

newMessagesRow = ArcadeDataSet.messages.NewmessagesRow

I'm loading my listview with records from a mySQL Table, which works great. But I'm having issues when I try to add records to another listview according the selected row in the first listview.

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 have two problems with my datagridview in VB 2005 that I did not encounter in VB6. I would like to add multiple records to a datagridview by allowing the user to tab and type.When they get to the end of a record and tab it should go to the next record like Access does. The user can move to the next record and it even shows the pencil on the left leading them to believe that a new record is being created. But, it will not create the record unless they first click on my button that will add the record with the code BindingSource2.AddNew(). I use a bindingsource to populate the datagridview. Here are some snipits of my code for clarity:
DataGrid2.DataSource = BindingSource2
GetDataDetail(
"Select * from [Order Detail] Where [Order Detail ID] = Null")

I have problem and I've been looking for a week now on how to solve it. Yesterday I thought I solved but apparently I didn't when I tried the query with new data added in my database.Here's my query
Public Function getTicketsByBeginstation(ByVal station As String) As Array
Dim r As Array
r = (From u In treinDataContext.Tickets Where u.ritId =[code].....
The problem I have is: when I have a station selected there are more than 1 trajecten (connections in English) but I had to use the .first else Visual Studio would give the error "the '=' operator is not defined for 'integers' and 'system.linq. IQueryable(of integer)".
So I give the name of a station -> I have to select all trajectens with the given station as beginstation -> I have to select all ritten which have the given trajecten -> I have to select all tickets which have the given ritten So: I have to show all tickets for a certain station.
I have following data in my table:
slno Name Age City
1 Ron 22 Dallas
2 Jonny 26 Texas

I have a form that is going to displays the same field from each of my 185 records. How do I get it to show all records for that field without using a data grid. If you think of this form as a layout of a parking lot and each field is a parking spot then what I am trying to do is display the assigned parking spots. When you click on the spot I want to open a second form that I already created to display and edit that spot.
