      Re: Window Form refresh

      i had window application, everytime run the app, the form_load event starts
      run , what I want to do is to refresh the form-load event every minute. the
      whole purpose is to refresh the app every minute.

      I try to use timer to call form_load, but it fails. so any advice?

      Thanks

        Re: Window Form refresh

        Hi Martin I am afraid it's not clear at all what you want to do.
        Anyway... generally talking... you can take the code necessary for the
        refresh and put within a sub (instead of under the load event)

        Sub RefreshMyThings
        'any refresh here
        end sub

        you can get this sub called by a timer. Just add the timer and schedule
        the refresh

        Private Sub Timer1_Tick(ByV al sender As System.Object, ByVal e As
        System.EventArg s) Handles Timer1.Tick
        me.RefreshMyThi ngs
        End Sub

        .... what this would be good for is a mistery ! :)

          Re: Window Form refresh

          Thank you, Tom,

          I knew what you said, take refresh thing into sub, then timer control the
          sub. what i want to do is refresh the window application every minute since
          starting run.

          one solution may or may not correct, that is timer to refresh form_load
          event to meet this requirement since form_load is initilize the application,
          but it doesn't work. any more advice?

          Thanks

            Re: Window Form refresh

            what are you actually trying to do? Can you post some simple code to
            explain the main idea?

                    Hi, Tom,

                    I try to set timer to run form_load every minute, but it fail. The code
                    snippet is below:

                    -------------Code start------------
                    Private Sub Form_Load(ByVal sender As Object, ByVal e As System.EventArg s)
                    Handles MyBase.Load

                    'call timer for refresh app every minute
                    TimerAppRunPerM inute()

                    End Sub

                    '*** create timer for refresh app per minute ***
                    Private Sub TimerAppRunPerM inute()
                    AddHandler comTimerApp.Ela psed, AddressOf ComOnTimedEvent
                    'Set the Interval to 60 seconds.
                    comTimerApp.Int erval = 60000
                    comTimerApp.Ena bled = True
                    End Sub

                    Private Sub ComOnTimedEvent (ByVal source As Object, ByVal e As
                    ElapsedEventArg s)
                    Form_Load(sourc e, e)
                    End Sub
                    ----------code end--------------

                    Thank you, Tom,

                    I knew what you said, take refresh thing into sub, then timer control the
                    sub. what i want to do is refresh the window application every minute since
                    starting run.

                    one solution may or may not correct, that is timer to refresh form_load
                    event to meet this requirement since form_load is initilize the application,
                    but it doesn't work. any more advice?

                    Thanks

                    Anyway... generally talking... you can take the code necessary for the
                    refresh and put within a sub (instead of under the load event)

                    you can get this sub called by a timer. Just add the timer and schedule

                      Hi Martin,

                      Hmmm... your code seems meaningless to me. Why don't you say what is
                      what you are trying to achieve. Do you wish your form to stay on *top*
                      of other forms? Do you wish to *activate* it every so often. Do you
                      wish to *invalidate* and repaint it or what? What does the form has on
                      it? What is the purpose of attempting a form reload?

                        Re: Window Form refresh

                        hi, Tom,

                        What I want to do is refresh the app every minute since the app strat
                        running. the form load event is retrieve data from db and bind dataset to
                        datagridview which display data from database. Since the data in the db is
                        update per minute, so the datagridview should refresh every minute to
                        display/reflect new data. I try to reload the form to achieve this, but it
                        doesn't work, any alternative solution?

                        Thank you a lot in advance

                        Thank you, Tom,

                        I knew what you said, take refresh thing into sub, then timer control the
                        sub. what i want to do is refresh the window application every minute since
                        starting run.

                        one solution may or may not correct, that is timer to refresh form_load
                        event to meet this requirement since form_load is initilize the application,
                        but it doesn't work. any more advice?

                        Thanks

                        Anyway... generally talking... you can take the code necessary for the
                        refresh and put within a sub (instead of under the load event)

                        >
                        you can get this sub called by a timer. Just add the timer and schedule
                        the refresh

                          Hi Martin, You have actually provided the answer yourself.
                          Don't put any working code under the load event.

                          If you need to refresh the grid, for some public display purpose,
                          you just re-run the extraction and binding code.

                          What I want to do is refresh the app every minute since the app strat
                          running. the form load event is retrieve data from db and bind dataset to
                          datagridview which display data from database. Since the data in the db is
                          update per minute, so the datagridview should refresh every minute to
                          display/reflect new data. I try to reload the form to achieve this, but it
                          doesn't work, any alternative solution?

                          Hi Martin,

                          Hmmm... your code seems meaningless to me. Why don't you say what is
                          what you are trying to achieve. Do you wish your form to stay on *top*
                          of other forms? Do you wish to *activate* it every so often. Do you
                          wish to *invalidate* and repaint it or what? What does the form has on
                          it? What is the purpose of attempting a form reload?
