    Realtime operations in database from VB code?

    Hello!

    Is there anyway in VB.NET (windows forms) to work in realtime on the
    database? I mean entering stuff in a textbox directly, updates the
    database...

    Best Regards
    /Lars

      ... I don't want to have to catch a KeyDown and then Update some DataAdapter
      ... that will be way to slow I asume!

          You cannot do anything in VBNet without code why than would you assume this
          will work.

          (The code is made by the/a designer when you are not making it)

          However you can use the executenonquery commands when you are meaning this.

          I hope this helps?

              Thanx for you answer!

              I'm not trying to do ANYTHING without code, just don't think the the
              KeyPress would be very good.

              I'm pretty sure I in VB 6 in a beginners lesson saw an example of an object
              that sort of looked like a database reader... that you could browse thru the
              posts in an access database in real time with and if you changed any values
              you didn't have to save or anything.

              If there are no such thing.. I need to prove to my customer that this is not
              possible to do in .NET and if you have anykind of link to a microsoftpage
              that will explain that using an Adapter to update (or execute non query)
              with is the ONLY and the best way... please post!

                  Lars,

                  In non Beta, (because I do not know what by instance the Express versions
                  are able to do in future) is as far as I know all done as you wrote.

                  dotNet is not a MS Access Application (what is bassicly not a devellopment
                  tool but an enduser application that uses the MS Access database).

                  I never saw a feature what can do what your customer wants in dotNet 2002 or
                  2003

                  However check this yourself to be sure it is not in there what the customer
                  wants and will be told to you in future.

                  Visual Basic 2005 Express:
                  http://lab.msdn.microsoft.com/express/vbasic/default.aspx



                  I hope this helps?
