    How to stop multiple click on Zoom function in the processbook ActiveX

    OlivierL

      Hello !

       

      When I click many time on the "Zoom In" or "Zoom Out" in the Process book, the activeX will save all my click.

      So when it finish to draw the new range, it will get the next one. When the ActiveX find the data, it freeze my application.

       

       

      So do you know, how can I drop all mouse click after click on a zoom button ?

      Or any other solution, which can stop to freeze my application when I click on those Zoom buttons !

       

       

      Regards,

      OIivier.

          Hello Olivier,

           

          Looks like you added some custom code to your display and the zoom may be interfering with your customization or am I mistaken and you are able to reproduce the behavior with a "standard" ProcessBook display?

          If the issue is with custom code, we need to know more about it and may even have to reproduce before being able to think about a potential solution.

              Hello,

               

              Thanks for your answer !

               

              My problem is the same if I use ProcessBook. If In ProcessBook you create a graph, and you click a lot of time on the zoom - button, the Processbook application will freeze. After the freeze, it will continue to dezoom (and re-freeze the GUI) until all click in queue are done !

              So I would like that the GUI Freeze only one time, and after the plot, the processbook drop all mouse event to stop the next zoom request.

               

              Regards,

              Olivier.

                  Hello Olivier,

                   

                  I don't know how many times you click until you see the ProcessBook trend freezing. I wasn't able to reproduce the issue you describe but can imagine that you are looking at a trend with one or more busy points and when zooming out the trend data retrieval takes a good amount of time causing the trend appearing to be frozen.

                   

                  The screenshot you've posted shows a trace of SINUSOID rendered with more details than I am used to. It almost appears you have not just disabled compression but also increased the scan frequency. I would be interested what period is showing for the trend when it appears to freeze? Please note start- and endtime for the trend and try to figure out how much events the PI Point has for the period e.g. by asking the event count using PI DataLink.
