I am connected to a SQL Server Compact Edition Database. One of the tables involved has 3 columns - CompanyID, CompanyName and CompanyNotes. I have created a form in Visual Basic to add a new company to the database, and of course I don't want the user to have to manually put in the company ID.
In the dataset.xsd I have created an INSERT SQL query that simply inserts a new row with the CompanyID, CompanyName and CompanyNotes. I have set the CompanyID to auto-increment. However, when I tried inserting the name and notes it didn't like it because I set the ID field to be mandatory. How will I insert the new company data into a new row with a new ID?
The very basic code I currently use for adding a new company:
Private Sub btnSave_Click(sender As System.Object, e As System.EventArgs) Handles btnSave.Click Me.CompanyTableAdapter1.AddCompany(??????????, txtCompanyName.Text,

I have a teradata backend that uses auto increment. The form is databound i.e dragged a column to the form which gave me the navigation header etc.The problem I'm having is when user 1 opens a record the auto increment goes +1, let's say we're at 45 now, then user 2 opens a new record and it also goes to 45 as user 1 has not saved. Why is the databinding not locking 45 when the first user opens it
This feels like a completely basic question, but, for the life of me, I can't seem to work out an elegant solution.
Basically, I am doing a LINQ query creating a new object from the query. In the new object, I want to generate a auto-incremented number to allow me to keep a selection order for later use (named Iter in my example).
Here is my current solution that does what I need:
Dim query2 = From x As DictionaryEntry In MasterCalendarInstance _ Order By x.Key _ Select New With {.CalendarId = x.Key, .Iter = 0}
[Code]....
Is there a way to do this within the context of the LINQ query (so that I don't have to loop the collection after the query)?
I am trying to make a sample Master-Detail relation ship database example in vb.net. When I add MasterTable a new row via bindingnavigator and save via savebutton autoincrement field goes -1 -2... negative values hence cannot get correct ID numbes saved in table rows till I close open sample application. How can I see correct autoincrement ID numbers in gridview after savebutton ?.Just ID numbers saved to mdb.but cannot see them i gridview and displaying negative weird numbers. This problem is important because without getting ID numbers cannot bind Detail table rows to newly recorded master table rows.
