[Code]...

I've got a simple mdb database set up in Visual Basic Express Edition (winforms) and I'm trying to update data from a datagridview to a database. I've databinded the textboxes to the columns I want in the datagridview and this works great. After some struggling, I've finally managed to have the values updated in every row of the database. But, trying to modify a newly created record throws this error:
"Concurrency violation: the UpdateCommand affected 0 of the expected 1 records"
I mean, it seems as though the error only happens with newly created rows. Because closing the application and reopening it immediatly, I'm allowed to update the values of the cells.
I also noticed that the ID of the row is set to "-1" when I've just created a new row. The other rows don't have a negative number for ID. Could this be the cause? Seems as though the row isn't really updated to the database.
So this is the code for the AddRow button
Dim newRow As MusicDBDataSet.SongsRow
newRow = MusicDBDataSet.Songs.NewSongsRow()
newRow.Name = txtBoxNewName.Text
newRow.Genre = txtBoxNewGenre.Text
newRow.Rhytm = txtBoxNewRhytm.Text
[Code] .....
But thinking about it, the textboxes used to update the values of the newly created row are databinded to the database or tableadapter itself right? Could it be that the UpdateCommand fails because the row hasn't really been created properly yet?

I have created an application which ticks and unticks a routing sequence. But whenever I click on my save button after tickin the required, I get an exception thrown at me stating "Concurrency violation: the UpdateCommand affected 0 of the expected 1 records". My code is as follows:Private Sub OKButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OKButton.Click
'Displaying the rows in the dataGridView.Me.myadapter.SelectCommand.CommandText = "SELECT dbo.WR010130.RTSEQNUM_I, " _& "RTSEQDES_I, SCHEDULESTARTDATE_I, DONECB_I, " _& "CLOSEDBY_I, DATECLOSED_I, TIMECLOSED_I, SCHEDULESTARTDATE_I, WCID_I " _& "FROM dbo.WR010130 JOIN WO010032 ON dbo.WR010130.MANUFACTUREORDER_I = dbo.WO010032.MANUFACTUREORDER_I " _& "WHERE dbo.WR010130.MANUFACTUREORDER_I = '" & MoNoComboBox.Text & "' AND (dbo.WO010032.MANUFACTUREORDERST_I = 3 OR dbo.WO010032.MANUFACTUREORDERST_I = 7)"

I am working on a program whereby insert, update and delete of database is required, i have been able to do so successfully but the above error occurs when i tried to insert a new row of data into the database and tried to edit it and update it to the database. The database platform i used is SQL server 2005 and i am using datagridview to display my data, my primary key is "s/n" which is an auto number, however, whenever after i insert data into the database, the newly added row has the "s/n" column blank shown in the datagridview and after i edited that row and tried to update it, the error occurs.

None of the "answers" that I have been able to find, address the problem. I am using oledb to read and update a MS Access DB in an ASP.NET application.I read the member dataset and fill it using the data adapter.I modify the row of data in the dataset.I then use the data adapter to update the row and get the error shown in the subject.
I am an experienced developer using ado.net on sql server windows application via the data adapter, so am familiar with how this should work.
I have searched everywhere and am hoping that someone here at Microsoft might have the answer.

My client recently got this error but I can't reproduce it on my pc. Any Idea what the problem could be. I have a master/detail scenario. So I have a grandparent/parent relationship, so when I select a product from my product combobox it displays the relevant results from the Result_Header table in my first datagridview.
Then I have a parent/child relationship so that when I select a result_header item from my first datagridview it displays the child records from the Result_detail table. If i'm adding a new Result_Header and then click save, I search for existing tests for the chosen product and insert them as new datarows into the Result_detail table. then I can update the child rows and click the second save button and it saves what I edit. Quite complicated.

I'm trying to update a Access database. I'm new to this and I've reviewed an Ado tutorial early today. I'm trying to apply what is taught but I'm getting an error message and I can't seem to get passed it.
In my code I have an Add, Update, and Delete process. The Add and Delete processes work just fine. It is only when I go to update the database that I get the following message."Concurrency violation: the UpdateCommand affected 0 of the expected 1 records."

This code used to work but for some reason it doesn't anymore. I get the error "Concurrency violation: the DeleteCommand affected 0 of the expected 1 records." I checked to see if the values were in the db and they were, by the way I'm using Access 03. I commented out the try/catch block and got the error when trying to update the ds.

Update requires valid UpdateCommand passed DataRow collection modified rows. When I run the following code. But the strange thing is that I have similar code on another form and it works great. The only difference is the database table is different. I verified both tables and they look identical, as far as settings. I have verified that _Non_MS_Office_Licenses has a primary key that is unique. Looking in dataset manager I see the query for fillBy() is fine and it has all the insert and update stuff. At the end when it verifies it says all is verified when I configure the dataset
Dim row = FrmApp.Non_MS_Office_LicensesBindingSource.Current
row("Primary User") = Replace(CStr(TxtUserid.Text), "'", "`")
row("Staff Last Name") = Replace(CStr(TxtLastName.Text), "'", "`")
row("Staff First Name") = Replace(CStr(TxtFirstName.Text), "'", "`")

I'm having trouble updating a sql server database with a dataset using a dataadapter. I have used the dataadapter with success in the past when adding new rows, using a single table, and just calling the dataadapter.update command.However, I am now running into a more complex scenario and I need to use dataadapter.UpdateCommand method and I'm having lots of problems.
The sql statement that I'm using to fill the dataset looks like this: "Select [Order Details].ProductID, [Order Details].UnitPrice, [Order Details].Quantity, [Order Details].Discount, Products.ProductName From [Order Details] INNER JOIN Products ON [Order Details].ProductID = Products.ProductID Where OrderID='" & strOrderID & "'", sqlConn"
This is pulling the data from 2 different tables (Order Details and Products) and then joining them and filling the dataset, and I am seeing the exact results I want. I am then binding the dataset to a datagrid control that allows the user the option to edit the datagrid, which in turn updates the dataset.
So that being said how do I get the updated dataset back into the database? I tried using dataadapter.update but it informed me that I now need to use dataadapter.UpdateCommand. Ok, so I've looked up how to use UpdateCommand but I cannot for the life of me figure out how to set up the right sql command statement. Part of what has me confused is the UpdateCommand examples I have seen are working with a specific row and updating that rows data. I can get that to work but I want all changes to the dataset to persist and update to the database when the user is done working on the datagrid.
Also, the examples shown set up command parameters but again, this is only confusing me because I just want to send the whole dataset back to the database. It seems like the parameters are saying "Ok, this specific row in this specific dataset.table, update these specific fields in this specific database". I'm not sure how to accomplish that when working with a datagrid.

I have a table in Access with two key fields (let's call them Item and Cust). These key fields *combined* are the primary key. So each record must have a unique Item and User combination. It can have a duplicate Item with other records, and a duplicate Cust with other records, but not a duplicate of both. Because my "primary key" is a combination of two fields, I can't make a primary key on the table in Access (it only supports one field as a primary key).
I have another table in SQLServer which also has Item and Cust, but in addition, is has several descriptive fields that give more details about the Item and Cust. I'm trying to use ADO.NET to bring in that SQL Server table and UPDATE some matching fields in Access with the descriptive fields. [Code]

I have looked at multiple posts regarding this issue, but can't seem to find a solution. To keep it simple I have an Access database with a single table. It does have a field as a primary key. When I click the save icon on the Binding Navigator I get this error having to do with the following code:
Me.Validate()
Me.TitlesBindingSource.EndEdit()
Me.TitlesTableAdapter.Update(Me.VFCurvesDataSet.Titles)
I cannot set the Refresh the Data Table check box in Advanced Options of the TableAdapter Configuration Wizard as it is grayed out. Once again, I have a primary key.
The posts I have reviewed indicate that an UpdateCommand needs to be created, but I can't understand how it should be done. W

im new to vb.net 2003 but have used vb 6 for years and dabbled with 2005. A program that would usually take me a few hours to make i am on day 5, 4 and a half of which have been trying different ways to get it to update, and not one of them will post the information back to the SQL 2000 database I am actually going insaine.
The best i can get out of it is this error. "Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information" I have googled it and come up with the fact the primary key isnt set right, but i still cant get that to work. Here is the peices of code that are relevant.
