Control How A Table Adapter Is Filled
Jan 9, 2010
How can I control what is filled into the table adapter at runtime? Basically, I have a table full of thousands of rows, and I want to limit this to just 1 row. I want to specify an ID number and be able to pull up that row in the table, and I need to do this at run time. What are my options, and what is the easiest way? I want to make sure the data is still linked to the original row in my database, that way the changes are saved properly.

I have a data table whose one column is related to a column of another table. I have a listbox in a form which shows a column (which is sorted by another column value by ORDER clause) of the parent table and other columns are in textboxes. The child table is represented by a datagrid. When I add a new item in parent table and click save, the newly created item is listed at the bottom of the listbox violating my ORDER clause. When I wrote some codes to fill data again after updating, it shows an error message[code]...

I added a table to my Access database. I added that table to my dataset. Using Database Designer VB Studio, my table and tableadapter show up in the design view. The class definition is in the datasetdesigner.vb, and it shows in the object browser. But, I can't reference it in code. I am a newby and obviously missing somethning.

I have a form that fills a table adapter with this:
Me.Scratchpad3TableAdapter.Fill(Me.MDRDataSet.scra tchpad3
and what I'd like to do is when users edit something on this form that they post the changes to a table called exceptionsedit which is not part of that dataset. What I don't know how to do is to how to insert those edits to the exceptionsedit table.

We are filling a combobox with information of a table. (we read a field for filling the combobox and the id)
It's necessary that if we choose an item in the combobox we also get the id of the table.How do we put the id into the combobox so can read this id after selecting an item.

I have a form and it is databound to a Access table with the standard TABLEADAPTER wizard. All works well HOWEVER, new records are not displayed in sorted order.When I add a new RECORD, it can go anywhere within the table. When I move around the table using the TABLEADAPTER Manager, the newly added record does not appear in sorted order.Furthermore, when I restart the application and show the form (which issued a FILL command), the records are not sorted.The SELECT I am using is fairly simple:
SELECT [list of fields] FROM TableXYZ ORDER By [sort field]
This HOWEVER, does not appear to work.get the table to be sorted when filled?Other information - the table in question has the field that is specified in the ORDER BY clause which is the same as the Primary Key.As an example, in the table there are records with the following KEY:
4313, 4314, 4315
When I insert a new record, it might fall between 4313 and 4314. Lets assume I add 9999. I expect it to be at the end of the list however, it appears between 4313 and 4314.FYI Also tried this in the code as well:
TableBindingSouce.Sort = "field1 ASC"

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?

I have a table adapter that I use just to fill a form when it loads. I've added two new columns in the backend and went in through the "DataSources" and added them. They appaear in the XSD designer but for some reason are not filling the form when it loads. I the form is writting to the backend correctly via hand coded SQL.

I have code in vb.net that was created using Visual Studio 2008. It has got queries done via data sets and table adapters. dsStagMyfileDesigner.vb and dsStagMyfile.xsd are the files having all the sql queries. They are code generated by using data table adapters I believe. Editing them might screw the system.

I'm currently trying to create a system which stores different cases for clients using Visual Studio 2010.When adding fields from the database a table adapter is automatically created.Me.TblMattersTableAdapter.Fill(Me.MJPAccessDataSet.tblMatters)Now my problem is that each case may be at a different stage. They are either 'Active', 'Closed' or 'Archived'.So my question, is there a way to filter these results? I've tried creating DataTable and only adding the archived cases but I couldn't get it to work. I was trying.

I currentt have three tables, using a table adapters and datagridviews I would like to add a new record to each table. the only problem is that the primary key from table 1 is a foreign key in table 2 and 3. Is there a way to add a new record in the table adapter without sending it to the DB and get a predicted primary key so I could put this as the foreign key in tables 2 and 3.

i'm using vb 2008 and local database sql server compact 3.5 to build a application.the problem is that i can't insert a new data to the database from the app. i'm wrote the query right at dataset and using table adapter. but when i call the query, it succeed but the data don't exist at database.why when i add data, it's not working. actually when i run it, it says that adding process is success, no error, and it shows at the datagrid. but when i look at database. the data that i add is not there.and in tableadapter, i also make sortData, seachData query, i can use both of them perfectly when i run the app.so, i really confuse why is the insert query didn't work.

I have a form that has a datagridview and a table adapter that displays data from a SQL database. What I'd like to do is that when edits are made to the data in the datagrid, I'd like to post all of the data back to the table. I know that you can do that with a dataset and a data adapter, but I don't know how to do that with a table adapter. Here is the code for my page:
Public Class ExceptionEdit
Private Sub ExceptionEdit_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'MDRDataSet.scratchpad3' table. You can move, or remove it, as needed.
[code]....
When people click on the Save Exception button, I'd like to save back to the update the database with the new data.

I can do this easily with table adapter, but I can't seem to use variables in the table adapters connection string, or specify the connection string to use before "filling". Is there a way to populate the form without using any sort of binding? Currently I've used this method - a search form that populates a list box, and on the double click action I have this:
Private Sub lstResults_CellMouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles lstResults.CellMouseDoubleClick
'Fills Main Form
Dim firstcellvalue As String = lstResults.Rows(e.RowIndex).Cells(0).Value.ToString()
frm_IMT.intPendingID = CInt(lstResults.Rows(e.RowIndex).Cells(0).Value.ToString())
frm_IMT.Show()
Then When the form loads:
Me.PendingTableAdapter.Fill(Me.Phone_memo_backendDataSet.Tables("Pending"), intPendingID)

I'm having a hard time wrapping my head around data access in VB2010. I have properly set up a datagridview, table adapter etc... I have only 3 columns showing (out of 7 that are stored) in my datagridview (dgv for the sake of less typing).i don't show the ID column which is the unique index. It's hidden.what I want to do is have a button on each row (already done that) that, when clicked, deletes the row from the dgv AND the database. I have been able to get it to remove the row from the DGV, but not the underlying database. My background is in VB6 so i'm sort of flailing around in the dark here. I tried using [code]

connectionString="Data Source=########;Initial Catalog=DowntimeD51;Persist Security Info=True;User ID=#######;Password=########;Connection Timeout=120;Encrypt=False;TrustServerCertificate=False;Network Library=dbmssocn" I have the above connection string in a vb windows application , This is part of my app config file.
I then have a number of table adapters for connecting my business logic to the database , One of the queries inparticular is a pretty large one and requires extra time to complete however the connection is getting a timeout error. When I checked the adapter connection with Dim connection2 As Int32 = Adapter1.Connection.ConnectionTimeout This shows the connection time out to be 120 seconds but the timeout is still occuring after 30 seconds.

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
