Update ms access database via vb.net

How can I do that?

I already have the code I'm working on but it seems that it doesnt work really fi开发者_JAVA技巧ne. Here is how my program works. I input an id number(unique) on a text box and click the search button. The entries that corresponds to the id number is then displayed on the other text boxes.

And then I try to edit one of the entries manually(changing its letters or name) then I click the update button.

Here is now the problem: It really updates the entry but it makes a mirror of the entry with a different id number(maybe automatically generated). So basically the ms access database will now contain the old entry and the updated version of the entry.

I can show you my code if you wish to. As long as I am assured by your reputation in this site.

Show the code, seems like you are using insert instead of update.

OK, check this link DataAdapter.Update Method

You seem to be missing

' Without the OleDbCommandBuilder this line would fail.
builder.GetUpdateCommand()

before

adapter.Update(dataSet)

Let me know if this works?
