Updating Data From A Table Adapter

Apr 18, 2006

Honestly I do not understand why I need to write code to update a databse and why it stores it localy. I'd simply rather the system update the individual row after it is scrolled off of.

In either case since I guess I can't do that.

Here is some code in a button on a form

Try
ItemsTableAdapter.Update(NewCreationsDataSet1.Items)
LineCodeTableAdapter.Update(NewCreationsDataSet1.LineCode)
Catch ex As Exception

Concurrency - Restore A Dataset To The Previous State Before Updating The Database With A Data Adapter?

Dec 10, 2009

How do you restore a dataset to the previous state before updating the database with a data adapter? I have a concurrency update problem that I believe to be caused by this. The update fails during the update and a rollback command is issued using a SQLTransaction object. However, now the rowstates of the rows that did not have errors have been changed to unchanged. So this record is no longer availible to be inserted into the database. When I updated the value that could not be null and then test the second update which runs just as the first does then I get a concurrency error. The update code is below:

Update Data From Data Set And Table Adapter

Oct 6, 2010

I have a windows form program that pulls data from a sql server. That same data is being read from a ASP.NET website that sets properties for the site. The SQL server has 3 tables: tblWebPage, tblObjects, tblProperties. and 6 views for the 6 web page: vWebPage01, vWebPage02, vWebPage03..ect. When the program loads you see buttons for each web page on the site. When the user clicks on the Home Page it loads this data: [code]Now, the problem lies in updating vWebPage02, vWebPage03, ect.. I assume with the same data I can copy my form with the code and change the form name and the data set to build and update. So that's just what I did changed the form name where needed and changed "vWebPage01" to "vWebPage02".When I tested the program My "vWebPage01" form it built and updated no problem. when I went to test "vWebPage02" it built the dataset and table adapter fine but it did not update at all.

Selecting Specific Data To Fill A Datasource Table Adapter?

Sep 15, 2009

I have a datasource linked to a table in a database.When I wnated to display this data on a form, I just dragged the datasource onto the form and it did everything for me, including the code to fill it;

Me.ProjectFileTableAdapter.Fill(Me.ProjectFileDataSet.ProjectFile)

My problem, is that this program will have multiple users, and I don't other users to be able to see each others data. So the problem with the above statement is that it fills the table with ALL the data in the datasource. How can I make it only display data that is for a specific user?Here's the code that is used to fill the tableadapter:

DB/Reporting :: Updating Client Data Tables When Data Table On Shared Drive Is Updated?

Sep 28, 2009

I would like to know the best, or standard, way to accomplish real-time client updates in a small multi-user application using an access data table as a data source.Specifically, this application will be used by 3-4 people. It uses a datatable which is filled on form load and bound to a datagrid at design time. The datatable is stored on a shared drive. The data table on the shared drive is updated in two ways:

1) Users can update the datagrid which then updates the datatable on the shared drive via the data adapter's Update method.

2) A server application does some work on some text files, periodically updating the data table.

I need the clients to reflect the changes to the data table on the shared drive as closely to real-time as possible. I know that the data table stored in memory on the client is disconnected from the data table on the shared drive, so I must query again to get the updates.

1) Is there an alternvative model I can use which is connected, and which will automatically reflect the updates in the data table on the shared drive?

2) If not, what is the best way to check for changes in the data table (so I can know when to call the data adapter fill method)? I am planning to poll the drive for a change to the .mdb file, raise an event and then fill the data adapter when the event is triggered. I am using this method successfully now to check for changes to a text file in another application, and I know how to implement it?

Refresh Combobox Values After Updating Its Datatable And Adapter

Jul 8, 2008

on a windows form i have a combobox called currency, it is populated by a table-adapter called exchan-gerate which is turn populated by a dataset called mydataset. on form load, i issue update commands to the back-end database that holds the table which populates the dataset - they work. if i look at the update to the combobox, they are not reflected until i exit and restart the app - then they're fine. further down the form load i've tried:

Me.exchangerate.Update(Me.DataSet.Currency)
Me.CurrencyComboBox.Refresh()

am i missing something silly to have the values in the combobox change and refresh at the time of the update to the database? as i said, an exit and restart of the app displays the accurate data.

Accessing And Updating An Access Data Base Via A Table Index?

Feb 18, 2011

I am an old VB2 programmer and in the process of moving up. In VB2 I could obtain a data row via and index on an access table. I can not find an example on how to do this. I can retrieve a single row using a query, but an index would be faster. I know in Oracle use can use a hirt to direct the query to use the index.Here is what I was during in VB2 (Sample) with no hint.

Set Stock_Tbl = "DataBaseName".openTable(Stock_Tbl_Name)
Stock_Tbl.Index="Symbol_Idx"
Stock.Tbl.Seek="MSFT"

Client Database From Dialog Box Not Updating Table View Of Data Collected?

Apr 20, 2012

I am currently working on a Database that collects information. Firstly, i use a new windows form to collect that data. I have it set up to where, when the form loads, the database is ready to collect the information fields. And then the form closes on the button click to add that data, it does not update that data table view. It adds it once i close the program and debug it again.

Code: (Open the windows form)
Private Sub btnAddNew_Click_1(sender As System.Object, e As System.EventArgs) Handles btnAddNew.Click
AddNewClientData.ShowDialog()

[Code].....

Problem two: I need to make a button that will increment a cell that was set as an Int, by one, but can't figure out how to put it into code.

Get Id Value With Table Adapter?

May 29, 2010

To get an id value after a table insert into an Access database you do a SELECT @@IDENTITY. I would like to know if this will work if your INSERT query is a table adapter query? I created an INSERT query for a table in the dataset designer which is working. My concern is that if I make another query with SELECT @@IDENTITY it won't work because table adapters make a new connection each time. Can someone clear me up on this?
