Stop WebGadget accessing the internet

[ricardo]

I investigated a little bit more.
The hanging is caused by the CSS file, which unfortunately does not seem to obey DLCTL directives.
In your example page the file is named bundle.css.
A quick hack to disable the loading of the CSS file is to rename it to a different filename (eg, disabledbundle.css)
Then the page always loads instantly in my tests.

(If you'd prefer to preserve most styles in that file, there's another quick hack which I'm still testing at the moment)

Id the problem is the CSS file, the solution is Meyer's CSS reset (vert well know) or any other CSS reset:

Code: Select all

html, body, div, span, object, iframe,
h1, h2, h3, h4, h5, h6, p, blockquote, pre,
abbr, address, cite, code,
del, dfn, em, img, ins, kbd, q, samp,
small, strong, sub, sup, var,
b, i,
dl, dt, dd, ol, ul, li,
fieldset, form, label, legend,
table, caption, tbody, tfoot, thead, tr, th, td,
article, aside, canvas, details, figcaption, figure, 
footer, header, hgroup, menu, nav, section, summary,
time, mark, audio, video {
  margin:0;
  padding:0;
  border:0;
  outline:0;
  font-size:100%;
  vertical-align:baseline;

/* change colours to suit your needs */

  border-top:1px solid #cccccc;
  margin:1em 0;

input, select {

ricardo, how do I call that? I tried this which (obviously) doesn't work. I know nothing about proxies.

Code: Select all

SetProxy1("",0,0)

You need a proxy, in the exmaple i put just an imaginary number, you need to put your own

Code: Select all

SetProxy1("152.98.42.35", "8080")

String Size - I see, it is actually an IDE limit but the error message does not suggest that!

In case someone still has a need for this, calling the following procedure (InitOfflineWebGadget) works fine for me:

Code: Select all

Procedure InitOfflineWebGadget()  
  Structure S1 
    mode.i
    *pNextHop
    *pStub
  EndStructure
    
  owg.S1
  owg\mode      = 3  
  owg\pNextHop  = @"0"
  
  CallFunctionFast(GetFunctionEntry(OpenLibrary(-1,"urlmon"), 241), 38, @owg, SizeOf(S1), 0) 
EndProcedure


;;; Testing

OpenWindow(0, 0, 0, 800, 600, "OFFLINE_WG") 

InitOfflineWebGadget() 
WebGadget(0, 10, 10, 780, 580, "C:\testfile.html")    

Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow

Just saw this, and tried it with high hopes, but it doesn't work here. The WebGadget still hangs for over a minute while trying to load external resources with my test HTML file. Thanks for trying to help!

Just a shot in the dark: try replacing

owg\pNextHop = @"0"

With one of the below:

owg\pNextHop = Ascii("00.00")

or

owg\pNextHop = Ascii("FE80::1")

or

owg\pNextHop = ascii(“localsystem”)

Tried all 3 with no luck, firace. I'll do some searching with StackOverflow again later.

Question: Do you need images and links to be active? If you are OK with no links/images, I may have a solution suitable for you (part of a feature I am building for my web browser)

Hi again firace. No, all I want is the HTML with no external links followed; see here -> viewtopic.php?p=556007#p556007

So if the HTML code is loading local files, that's okay, but not for loading external images/data from the net. Thanks.

You may want to give the latest version of Nessie (my toy, PB-based web browser) a try - specifically with the -offline command-line argument:

Code: Select all

nessie.exe -offline yourHTMLfile.html

Nessie homepage: https://www.radsix.com/

Does this offline mode match your requirements ?

Note that the browser source code is not currently available, but I can see if it's feasible to easily extract the offline viewing code.

Does this offline mode match your requirements ?

Yes, it does! Finally! Haha. It loads and shows the basic HTML without trying to load external resources from their links, as if my network was disabled.

I would very much appreciate it if you could post the relevant code that works the magic - I'm so curious to see what does the job. Thanks!

Great news! I'll send you a PM shortly.

Good day purebasic-ers fellows!

Is it possible share the code for offline webbrowsing?

Thanks in advance!

Give this one a try.
Depending on your exact needs, it could be sufficient.
