Can't open local HTML file with RevBrowser

[annettes]

I am trying to open a local HTML file in RevBrowser, in order to display a Youtube video. If I load the HTML file up to a website and access using the http prefix it works fine. But when I try to access it as a local file, stored in the same directory as the stack, Livecode hangs and the browser is not displayed. I am working on Windows 7 in the development environment and using Livecode 6.6.2.

This is the code I am using for the card containing the browser:

Code: Select all

on preOpenCard
   openBrowser
end preOpenCard

on closeCard
   closeBrowser
end closeCard

local sBrowserId, tPath

on openBrowser
   put the windowid of this stack into tWinID
   set the itemdel to "/"
   put the effective filename of stack "Food Chain" into tPath
   delete last item of tPath
   put "/dissolvedOxygen.html" after tPath
   put "file://" before tPath
  
  -- Open the browser, using the windowId and initial url
  put revBrowserOpen(tWinID,tPath) into sBrowserId

  -- Set some basic properties for the browser
  revBrowserSet sBrowserId, "showborder",false
  revBrowserSet sBrowserId, "scrollbars",false
  revBrowserSet sBrowserId, "rect", (250,220,900,600)
end openBrowser

on closeBrowser
  revBrowserClose sBrowserId
end closeBrowser

I have tried using "file:/", "file://" and "file:///" but nothing works. I have displayed the pathname of the file using answer and it is correct. There are no spaces in the pathname. What am I doing wrong?
Thanks.

You could try this, it works for me.

Code: Select all

...
  put "file:" before tPath ## <----
  -- Open the browser, using the windowId and initial url
  put revBrowserOpen(tWinID,tPath) into sBrowserId
  -- Set some basic properties for the browser
  revBrowserSet sBrowserId, "showborder",false
  revBrowserSet sBrowserId, "scrollbars",false
  revBrowserSet sBrowserId, "rect", (250,220,900,600)
  revBrowserRedraw sBrowserId ## <----
...

Hi annettes,

1. welcome to the forum!

2. Maybe you have some SPACES in your pathname? The browser does not like that!

Do this:

Code: Select all

on openBrowser
   put the windowid of this stack into tWinID
   set the itemdel to "/"
   put the effective filename of stack "Food Chain" into tPath
   delete last item of tPath
   put "/dissolvedOxygen.html" after tPath
   put "file://" before tPath
  
  ## The trick:
  replace SPACE with "%20" in tPath
...

At least worth a try

Hi 'anettes'.

I saw too late that you are on Win. It's presumably the missing partition name ("C" or "D" or whatever in your path). See below.
Also I prefer to use "file:" as prefix. Please, test both "file: and "file://".

Hi Klaus,
she has no space in her path (she wrote).
And using "file://" sometimes failed for me (for complicated file locations on external drives), but never "file:".

The following is tested on LC 5.5./6.6.5/6.7/7.0 and Mac+Win for a local file.

Code: Select all

# on Mac
local baseaddress="/Users/hh/Documents/"
# on Win
local baseaddress "C:/Users/hh/Documents/" --> watch the leading "C:"
#
# and then, on both platforms the same:
#
put revBrowserOpen(tWinID) into sBrowserId
# set here rect, scrollbars etc., then:
revBrowserSet sBrowserId, "url", ("file:" & baseaddress & "test.html")
revBrowserRedraw sBrowserId

With LC 6.7 and later this works also for revBrowserOpenCEF
(NOT on Mac for a local PDF, YES on Win for a local PDF).

On which version of LC and platform/OS did you run your script (could be interesting for tests of differences between revBrowserOpen and revBrowserOpenCEF)?

Hi Klaus,

Oh, yes, sorry, overlooked this one...

Hi Everyone,
Thanks for your replies. I tried what you suggested Hermann. The result is that now nothing is displayed. Previsouly when it couldn't find the file, the revBrowser would appear and there would be a message in it saying it couldn't find the file. Now I just get an empty space. I tried adding a border and scrollbars to the browser so that I would know if it was there or not, but these do not appear, so it seems like the browser is not being drawn.

The "C:/" was always present at the start of the path name. I display it in an answer box to check.

This is my code

Code: Select all

   put the windowid of this stack into tWinID
   set the itemdel to "/"
   put the effective filename of stack "Food Chain" into tPath
   delete last item of tPath
   answer question tPath with "OK"
  
  put revBrowserOpen(tWinID) into sBrowserId
  -- Set some basic properties for the browser
  revBrowserSet sBrowserId, "showborder",true
  revBrowserSet sBrowserId, "scrollbars",true
  revBrowserSet sBrowserId, "rect", (250,220,900,600)
  
 revBrowserSet sBrowserId, "url", ("file:" & tPath & "/dissolvedOxygen.html")
 revBrowserRedraw sBrowserId

Do you have any other suggestions?
Thanks,
Annette

Hi, could you please try a newer version (6.7.1-rc2 is very good), downloadable here:
http://downloads.livecode.com/livecode/
May be this is an old problem of 6.6.2.?
Perhaps Klaus knows more, he's a knowledgeable fox, I'm rather a greenhorn ...

Hi all,

although the DEFAULT value for VISIBLE is supposed to be TRUE, adding this is worth a try:
...
revBrowserSet sBrowserId, "visible",true
...

Hi Klaus and Hermann,
When I opened the livecode file again (in 6.6.2 initially), the border and scrollbars were visible, without having to set the visible property. Maybe I hadn't saved it properly last time. But still the browser was completely empty. However, it does take a long time before I can do anything else, so there is some processing going on. Then I tried it in 6.6.7 STABLE, but the same thing happened. I don't know why.
Thanks for your suggestions.

Does it work if you try to open a local html file with just some "hello world" text?
I wonder if there is an issue with trying to have the local file stream in from YouTube.

Hi all,

we are keen to solve your problem, because LC browser works usually fine.
Today I had also a display problem and tried the following:

Opened the browser demo stack of LC (Toolbar > Resources > Internet > Browser Sampler) and dragged the file to the browser window (not to the addressbar, to the display rectangle itself). It worked (and I found, that my file had an exotic encoding).

An easy way to test whether the browser is working. Did you already try this with several files?
