I read the other threads but i didn`t understood and none of the codes worked. I have 1 form with a Data Grid View bounded to the table Produse and 3 texboxes and 1 Save button.

In the save button i`ve putted the code : Using con As New Sql Connection("Data Source=.\SQLEXPRESS; Attach Db Filename=H:\Projects\Windows Application1\Windows Application1\Database1.mdf; Integrated Security=True; Connect Timeout=30; User Instance=True") Try con.

You can also call End Edit on the Binding Source in code to commit the new row. Click '---------------------------------------------------------------------------- Using con As New Sql Connection("Data Source=.\SQLEXPRESS; Attach Db Filename=H:\Projects\Windows Application1\Windows Application1\Database1.mdf; Integrated Security=True; Connect Timeout=30; User Instance=True") Me. And after (if this will be solved) that i managed again with your blog (john) to copy form one table to another and now i need to change that code too because i can`t refresh / update it.

If you want to create a new row in code then you use the Binding Source like so: The user can then enter the field values via the UI and the row is committed to the underlying Data Table when they navigate away to another record. Database1Data Set1) Dim new Row = Direct Cast(Produse Binding Source. And i have 3-4 columns in that row , how hould i do that , i tried some variants but did not succeed.

If you use a Data Grid View then that's all you need, because it allows the user to add, edit and delete records. displaying one record at a time, then you need to add a bit more code to add or delete records. End Edit() End Using End Sub It shows me the new record but when i close the application , it doesn`t save.

Using bind variables also improves query performance in the database, eliminates the need for special handling of literal quotation marks in the input, and protects against SQL injection attacks.

The following code shows a typical contains a client copy of the database data.
