[solved] How to send Chrome a refresh periodically

netmaestro · Post by **netmaestro** » Sat Dec 09, 2023 6:20 pm

I have a sales page which is always up during the day and it's displayed in Chrome. When sales are recorded on site the info isn't pushed, I have to refresh the page if I want to see the latest sales. I would like to write a small tool in PB that knows where the Chrome window is and refreshes it once per minute. My problem: no idea how to do that. Any suggestions would be much appreciated, thanks.

An alternative would be the webgadget I guess but the doc for it says it uses Internet Explorer 4. IE4 is 26 years old! Can this be right? If so, is it possible to hook it up to a more modern engine?

Thanks Fred. IE4 is older than PureBasic! Don't tell anyone else, this'll be our secret, OK?

You can place your page in an iFrame and then update it regularly:

Code: Select all

<html>

<body>

<iframe id="myFrame" src="https://yourSite"></iframe>

<script>
	window.setInterval("reloadIFrame();", 30000);
	function reloadIFrame() {
		document.getElementById("myFrame").src="https://yourSite";
	}
</script>

</body>

</html>

This code from Rashad might help:

I haven't tried it, but KCC was very happy it worked so I assume it works.

this works for me

Code: Select all

Procedure SendF5(window$) ; use part of window name  
  r=GetWindow_(GetDesktopWindow_(),#GW_CHILD)
  Repeat
    t$=Space(999) : GetWindowText_(r,@t$,999) 
;        Debug t$  ;to get window titles
  If FindString(LCase(t$), LCase(window$),1)<>0 And IsWindowVisible_(r)=#True
    t$=Trim(t$)
;    If t$ = window$ And IsWindowVisible_(r)=#True   ; use this part for full window name 
    w=r
    Else
      r=GetWindow_(r,#GW_HWNDNEXT)
    EndIf
  Until r=0 Or w<>0  
 handle = w     
  If IsWindow_(handle)=0 ; Does the target window actually exist?
    ProcedureReturn 0 ; Nope, so report 0 for failure to type.
  Else
    ; This block gives the target window the focus before typing.
    thread1=GetWindowThreadProcessId_(GetForegroundWindow_(),0)
    thread2=GetWindowThreadProcessId_(handle,0)
    If thread1<>thread2 : AttachThreadInput_(thread1,thread2,#True) : EndIf
    SetForegroundWindow_(handle) ; Target window now has the focus for typing.
    Sleep_(125) ; 1/8 second pause before typing to prevent fast CPU problems.
    ; Now the actual typing starts.
    keybd_event_(#VK_F5,0,0,0)    
    If thread1<>thread2 : AttachThreadInput_(thread1,thread2,#False) : EndIf ; Finished typing to target window!
    ProcedureReturn 1 ; Report successful typing!  :)
  EndIf
EndProcedure

Debug SendF5("window title")

Thanks, 6theo4, that works perfectly for me! Thanks as well to all who gave ideas, it's much appreciated

You only need to see an animated GIF from KCC to know some code worked.

Ok, so this is just weird now. The code from 6theo4 works perfectly, refreshing my window at the selected intervals. But only if run from the IDE. If I compile the code, add it to my taskbar and run it from there it does not work anymore. Anyone have an idea?

maybe forgot to remove the "Debug" ?

Yeah, the iFrame html approach did not work for me.
And sendkeys will probably get blocked in the future.
