call a method in the beginning before using this adapter (say in main form after you create instance of it).

Whilst one can subscribe to the tableadapters underlying adapter in the tableadapter partial class I find you cannot easily initialise it without having to remember to call an initialisation of your own.

Properties class Program Data Adapters and Data Readers Row States and Row Versions Accept Changes and Reject Changes Merging Data Set Contents Retrieving Identity or Autonumber Values ADO.

I'm currently working on a program that allows for connections to multiple provider specific databases, so obviously I'm using the non-provider-specific classes (in System. Common) to work with these various connections once the connection or data adapter has been instantiated through the use of the provider's implementation.

Records that don't exist in the new CSV shouldn't be deleted, however.

I've been playing around the example from the MSDN library.

Otherwise, it works fine, and now I have provider-independent event handlers available from the Db Data Adapter class (which is how Microsoft should have implemented them to begin with). ''' Public Delegate Sub Row Updating Event Handler(sender As Object, e As Row Updating Event Args) Public Module Db Data Adapter Extension Sub New() End Sub Private Function Get Event(event Name As String, type As Type) As Event Info Return type.

Get Event(event Name, Binding Flags.[Public] Or Binding Flags. Declared Only) End Function ''' Public Function Add Row Updated Handler(adapter As Db Data Adapter, handler As Row Updated Event Handler) As Boolean Dim upd Event As Event Info = Get Event("Row Updated", adapter.[Get Type]()) If upd Event Is Not Nothing Then Try If handler.

v=14625 if you look at this video you can see, that you just double click on something in the dataset designer and the event gets generated and wired up for you...this works only for VB programmers :)) sux // Assumes that connection is a valid Sql Connection object. Row Updating -= new Sql Row Updating Event Handler(On Row Updating); cust Adapter.Sql Data Adapter cust Adapter = new Sql Data Adapter( "SELECT Customer ID, Company Name FROM Customers", connection); // Add handlers. Row Updating = new Sql Row Updating Event Handler(On Row Updating); cust Adapter. Row Updated = new Sql Row Updated Event Handler(On Row Updated); // Set Data Adapter command properties, fill Data Set, modify Data Set. The following examples demonstrate how to perform updates to modified rows by explicitly setting the Private Sub Adapter Update(By Val connection String As String) Using connection As Sql Connection = New Sql Connection( _ connection String) Dim adapter As Sql Data Adapter = New Sql Data Adapter( _ "SELECT Category ID, Category Name FROM dbo. Update Command = New Sql Command( _ "UPDATE Categories SET Category Name = @Category Name " & _ "WHERE Category ID = @Category ID", connection) adapter.

Fill(category Table) Dim category Row As Data Row = category Table.

New Row(); row1["Age"] = 10; row1["Name"] = "Smith"; row1["Temp Test Table Id"] = 1; var row2 = temp Test Table.
