Unable To Flip Through The Records In That One Text Box?

Nov 7, 2009

I have a blank form, and I've added a really simple Access database with two tables with two columns each. If I click and drag the name of one of the columns, and drop it on the form, I get a label and a textbox.

I was assuming that since the load procedure already had Me.WhateverTableAdapter.Fill in there, that when I pressed the green arrow to run the program, I'd be able to flip through the records in the column.

When I click "preview data", I do see the data is there, but when I run the program, it says 0 records and none load. Is there something else I have to do to be able to flip through the records in that one text box?

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 :

[Code]...

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.

2005 - Unable To Get Distinct Records From Datatable Using DefaultView.ToTable?

Mar 14, 2012

I am building a custom search control in VB.NET and came across a problem getting distinct records into my datagridview. I want to bring exact matches back first so I run 2 of the same query on the same table with a slight difference:

select ... like "code%"
select ... like "%code%"

I have a datatable that I need to get distinct records from; I am append records from a sql query to the end of the datatable so I cannot use a union in sql to return the dataset (I want to preserve the order which the rows are added) I have been using this which is working fine for 2 fields:

dt2 = dt.DefaultView.ToTable(True, "Code", "Name")

But when I have 3 (or more) fields I get duplicates ONLY for the row I am querying:

dt2 = dt.DefaultView.ToTable(True, "Code", "Name", "Initial")
select ... like "initial%"
select ... like "%intial%"

I am clearing the datagridview.source before rebuilding this. Is there a way to get the distinct rows this way or should I just build something myself to remove the duplicates from the second datatable before appending them to the new table?

Update Records In SQL Server Database?

Sep 28, 2010

I am using Visual Studio 2008 for creating a Winforms app. I have connected a database to it called XStats. There is one table in it called XGames and in that table 2 fields, XIndex (the primary key field) and GameNumber. Using the following code I can add records to the database, the data is taken from a text box, but once added I cannot view them unless I shut down the app and restart it.

con.ConnectionString = connectionString
con.Open()
Dim cmd As New SqlCommand

[Code]....

The existing records in the database are displayed on the form in detailed view via a binding navigator. How can I make it so that I can view all the records in the database, even those that are added during the current session. As will be obvious, this is my first attempt at creating and using a database with a win forms app,

.Net CommandBuilder Will Update, Insert, But Not Delete Records In SQL DB?

Feb 15, 2012

I have a datatable populated from an SQL Server 2008 database table. I created a DataAdapter with a commandbuilder to manage the updating, inserting, and deleting of records. The Updating and Inserting work as expected. However, Delete does not. The code runs through just fine without any errors. The number of records in the datatable after the row is deleted even reflects the deletion. The DataAdapter.Update works fine without any exceptions. But when checking the actual table in the SQL DB the deleted record is still there.Here are the parts of my code that deal with this table.

DGV Update - Allow Users To Edit Existing Records?

Aug 17, 2009

I have a DataGridView bound to a non-SQL Server database. I need to allow users to edit existing records but under certain circumstances I need to intercept the edit and instead of committing and updating the dataset I need to delete the edited record and re-add it as a new record. I have tried using every event I can think of to do this but haven't managed to get it right.

The closest I have got is with this:
Dim theRow As DataGridViewRow
Private loading As Boolean = True
Private rowLeft As Boolean = False
Private WithEvents cm As CurrencyManager
Dim copiedRow0 As String
[Code] .....

This almost works but sometimes completely messes up and re-adds rows twice and all kinds of other bad side effects. It seems a really simple thing to want to do but I just can't get it working.

How To Update Records On An Existing Access Database

Sep 28, 2009

how to update records on an existing access database using vb.net 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 vb.net 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.

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

Update Database Records Using Multiple Threads

May 27, 2012

Been a while since I did any VB work, and have started a new project that is a Windows Service that will update a database using multiple threads. I am testing this out with a dataset that consists of a "device name" and a "device IP", pinging the device, and attempting to update the device's "status".

I have it working in a single-thread type configuration, but would like to be able to ping and update different records across multiple threads (for obvious reasons).

The problem I'm having is with the logic mainly. When the service is started, I get all the devices from the database and fill a DataSet. From there, I am looping through the dataset's rows, pinging each device and updating the record. I know how to spawn multiple threads, but I do not know how to keep track of updating the correct record and also making sure that all records are checked in some kind of order. Like, if user specifies 5 threads, I need it to get record 1, thread finishes, gets record 6 (while other threads execute), or something like that.

Note: this does no interface updating or anything like that. Only updates a database record's field value.
