Form update of all connected sessions

[DanBarclay]

I tried to add timer on form and start it in procedure pRefreshForm, but it had no effect. If I understand correctly you advise me to add a timer on a form and set it to be enabled all the time ? That is a problem because update frequency should be 1 second or 1 hour, depending on the situation. We would like to monitor entrances to the building where user image is displayed to the receptionist each time a person checks in. So frequency should be 1 second in peak time, when a lot of people are coming to the building and much less otherwise.

Any other idea ?


ps: how come that webapplication.showmessage is shown ?

Does this work in the async procedure?

 

Code:

 for i := 0 to ControlCount - 1 do
  Controls[i].Invalidate

Another suggestion:

Code:

 js: string;
begin
 js := 'var form =  window.document.forms["SubmitForm"];' +
       'if (form) {' +
       '  form.submit();' +
       '}';
 WebApplication.CallBackResponse.AddJavaScriptToExecuteAsCDATA(js);
end;

Both from Alex some time back.  I haven't needed them so haven't tried.
