How To Get SQL Server CE TableAdapter To Commit To Database
Sep 19, 2010
Created dataset with tableadapter.Dragged dataset and tableadapter to the form so I can reference it in code.New records successfully add to the dataset but will not commit back to the database.Gives no error or clue why it won't work.TableAdapter insert statement was created automatically and is parameterized (@p1, @p2, etc.), but I am trying to avoid those parameter.add statements as I want to be able to use a field-by-field format without having to essentially repeat the schema of my database in code with parameter.add statements.Command object and INSERT statements work fine, but then you always have to construct an INSERT statement -- a pain if they're complicated.I want something as simple as working with a ADO recordset,but in .NET.What can I do to accomplish the following without parameter.add statements?

[code]So both methods seem to step through fine but don't commit the changes back to the database. This function is my only 'edit' function. It needs to look for the datarow which is to be edited. Edit it and then save the changes to the database.My other two functions create datarows and work fine. This one I just can't work out. I have a dataset with two datatables. This is running as a web service. Database is MSSQL.

I have a form with the following on it [code]then everything works as it should (as long as there is data in the text boxes) If there is one of the text boxes is left empty then an error is returned. The text boxes are not bound and the db is set to allow nulls. Is there an easy way to suggest that if name.textbox is empty then input "nothing" or dbnull etc.I have a lot of text boxes (approx 30) and ideally dont want to write if statements for each one. But will if i have to of corse.

I have to work in two parallel environments, developement and production, I want to use the same TableAdapter to connect to different databases (two Oracle databases running on different servers) with the very same structure. How is this possible?

I've been struggling the entire day trying to figure this out. Basically the data in my form won't save to the tableAdapter. To update the database I use:
Me.dataSetName.TableName.Rows.Add (DataRowName)
Me.tableAdapterName.Update(Me.dataSetName.TableName)
The database was created using SSMS 2008 R2 and I'm using VS 2010.
I have confirmed that the data is being stored in the data row (because when I removed data from the data row it wouldn't accept because there are NOT NULL columns) and I have followed the instructions of this form as well:[URl]..

AddNodesTableRows As SampleDatabaseDataSet.NodesRow
Dim i As Integer
For i = 0 To 10
AddNodesTableRows = SampleDatabaseDataSet.Nodes.NewNodesRow()
[code]....
End Try I've get no errors or exceptions from this code but it will not put the data into the database file. It always run through the "update successfull" yet nothing is ever written out to the file.

I have a table adapter for a fairly sizable piece of data. Now with this data I would like to give the user the ability to change the company name and have this reflected in the form on the drop down list of all of the companies once they have clicked submit. However, in order to do so I currently "Fill" the entire table adapter again to achieve this.Is there any way which I could just re-fill the company column from the database in the same tablea dapter.Here is my code for the sub:
Dim NewName As String = txtNewName.Text
Dim OldName As String = txtOldName.Text
Dim FieldName As String = Me.Text[code]...

I was working through Beth Massi's article, "Using TableAdapters to Insert Related Data into an MS Access Database" here: http:blogs.msdn.co...s-database.aspx
And I configured the TableAdapter exactly as shown by Beth, yet I am getting an error here:
Me.OrderDetailsTableAdapter.Update(newOrderDetailsRow) The Error says: "You must enter a value in the 'OrderDetails.CustomerID' field."
I am using this code for inserting a related record:
Namespace MyDataSetTableAdapters
Public Class AccessIDHelper
'<summary>
[Code].....
I am not able to insert and move on as I am getting the error marked above.
What could be possibly wrong with the above code and why is this giving an error ?

I'm using Visual Studio 2010 Express running on Windows 7 64-bit. I get the same error as detailled in this link [URL] .I need to work with some data to develop the system. I think I can only do this by changing the Copy to Output Directory file property to "Copy if newer" to prevent the debugger from losing it.However this causes TableAdapter.Fill to exit from the sub immediately after executing leaving behind the other code in the form "Add_Load" routine.

Maybe there is a better way to do this. The jist of I want is to have SQL Server raise me 2 types of errors: a WARNING and an ERROR from a trigger when I update a table. If SQL server returns a WARNING the trigger should COMMIT but show the warning to the user (using .NET - preferably through a SQL Exception which is only raised if severity > 10) and if it is an ERROR the trigger should ROLLBACK and show the ERROR to the user (through a SQL Exception).My attempts (needless to say this isn't working) at this was to have a trigger like this:
ALTER TRIGGER [dbo].[TR_TRANSACTION_UPDATE]
ON [dbo].[tTRANSACTION]
FOR UPDATE

I'm binding user settings to a bunch of controls on a WinForm dialog that has OK/Cancel buttons. While this works great to read in the bindings in, I would only like to commit binding changes if a user clicks OK, and not if they click cancel. Is there a simplistic setting to achieve this rather than managing all reading and committing myself?
Right now, let's say I have a textbox that binds to a user setting called "country". It has "United States" in it and if a user changes it to "Bolivia", that will get committed as soon as it is typed instead of when the OK button is pressed.

I have a DataGridView and in it a CheckBoxColumn, when I click a cell of that column the check box gets checked.I do it like this:
dgvMessages.CurrentRow.DataBoundItem("have_read") = 1
but the change does not get committed to the DataSource (or at least not immediately), so when I search through it I get wrong results.
I can't call AcceptChanges as that will refresh the grid and cause unwanted side effects... What can I do about this? Is there such a thing as an 'AutoCommit' property on a DataGridView?

I have developed a VB.NET program using a strongly typed dataset. This dataset has its connection to a SQL Server 2008 R2. The software should now be additionally used offline. The database should be exported to a *.sdf database. If no connection to the SQL server is produced, the software have to try to connect to the *.sdf database.I would like to achieve:
1. Export the data in the SQL Server 2008 R2 database to a local *.sdf file.
2. This *.sdf file has to work as an alternate connection string in the strongly typed dataset.
