[solved] How to send Chrome a refresh periodically

netmaestro · Post by **netmaestro** » Mon Dec 11, 2023 2:28 am

I've been trying the iFrame approach by Kiffi but without success. I slightly modified the code to make sure it's using html5 and edited the address to reflect my page but with both Chrome and Edge this is my result:

And here is the code I used:

<!doctype html>
<html>

<head>
<meta charset="utf-8">
</head>

<body>

<iframe id="myFrame" src="https://www.squareup.com/ca/en"></iframe>

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

</body>

</html>

If I compile the code, add it to my taskbar and run it from there it does not work anymore. Anyone have an idea?

In the compiled version did you remove the Debug statement?

Code: Select all

Debug SendF5("window title")

should be

Code: Select all

SendF5("window title")

Thanks 6theo4 and firace, that was it. I took the Debug statement out quite a while back and I thought I'd recompiled after that but I hadn't. Working perfectly now. Kiffi's code should work too imho but the server refuses to connect in both Chrome and Edge.

you should add an entry with the chrome title when your connection is interrupted so you can also get a refresh after a disconnection....

You should be able to use ReceiveHTTPMemory() to get the page's raw HTML periodically, and then parse that. I do it all the time to get info from my website. No need to muck around with a Chrome window and F5.

@BarryG, that's a great idea and I'll see if the site will talk to my computer. But it's a banking site so its security may not be something I can get through to. With the webpage I log in with my credentials and it sometimes gives me captchas and text messages containing 6 digit codes. I don't think my chances are going to be that good.

Which browser?

Chrome and Edge are based on chromium code. Both bowsers fail to connect certain websites. Dell.com connects but I did not inspect why the others fail.

Code: Select all

<html>
<body>
<!--
<iframe id="myFrame" src="https://www.dell.com"></iframe>
-->
<iframe id="myFrame" src="https://www.ibm.com/us-en"></iframe>
<script>
	window.setInterval("reloadIFrame();", 30000);
	function reloadIFrame() {
<!--
		document.getElementById("myFrame").src="https://www.dell.com";
-->
		document.getElementById("myFrame").src="https://www.ibm.com/us-en";
	}
</script>
</body>
</html>

That certainly changes things, NetMaestro, when a login and captchas are involved.

Without keyboard hacking involved:

Code: Select all

If OpenWindow(0, 0, 0, 600, 300, "WebGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered) 
  WebGadget(0, 10, 10, 580, 280, "https://www.purebasic.com") 
  AddWindowTimer(0, 123, 3000)
  Repeat 
    Event = WaitWindowEvent()
    If Event = #PB_Event_Timer
      If EventTimer() = 123
        SetGadgetItemText(0, #PB_Web_HtmlCode, "<script>document.location.replace(location.href);</script>")
      EndIf
    EndIf
  Until Event = #PB_Event_CloseWindow 
EndIf

Some website operators prevent their site from running in an IFrame. For this reason, my solution does not work.

+1 for infratec's solution.

There are different methods available to do it with javascript.

Thanks infratec but the site won't work in the native webgadget. But the WebGadgetEx by RSBasic works flawlessly. So I have a couple of solutions that are working now until Fred releases b1 of PB 6.10. Then the native webgadget should do the trick and your code will be the best and simplest solution overall. You're just a couple weeks early is all. I found your implementation of js very instructive as I'm pretty much of a noob when it comes to javascript.

There is also an other possibility: use the WebView2 runtime from Windows Edge

This implements a full working WebView2Gadget().
