Looking forward for your kind suggestions......1) Did you write that code? If yes, proceed to 2). If no, I charge 150 euros/hr. Let me know when you want me to start.
2) Post the code for a program that opens a text file with the following in it:
hello world
and prints the contents out using System.out.println().
3) Modify the program in 2) to determine if the file contains the word "yes". Post the code.
4) An html file is no different than the text file in 2).

FF16.02: opens webpage HTML file as code instead of webpage, seems to save as temporary .txt instead of html.

Hi,
I'm using FF 16.0.2
I have to open a link/attachment on a webpage that is a .html file.
When I click open, regardless of what software I use to do so: OpenOffice, IE, FF, notepad, wordpad - only HTML code is seen. This is what I assume to be because of what "jscher2000" mentioned - the URL is converted into a HTML.txt file.
Notably, if I go to the website on IE and open the HTML file through it, it works no problem. I have tried disabling addons.
I have been looking for fixes & addons to go around this problem, but none so far. First time posting!

See my answer here: [[/questions/930461#answer-378263]]

Opening additional html file in same broswer window

Hi here is what i wasnt to do i will write the whole process in sequence to make it clear.
1. write to html file [accomplished]
2. open html file from GUI in browser window [accomplished]
3. rewrite html file from within GUI [accomplished]
4. reopening the html file in the SAME browser window [the problem]
Any one know if this is possible?
here is the code im using to open the initial window...
Process proc = Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler results.html");

Ok heres what im doing...
im using googles api..and in my GUI i have a "Next 10
results" button, i could refresh the page X amount of
seconds but this isnt really ideal.
But looks like that is what im gonna have to to do
...unless anyone else has any better suggestions?
(ps. i dont want to go down the JEditorPane path....
=] )Well then if you dont want to refresh the page, then you can have 2 pages.. The second page would be just this
<body>
</body>And include this HTML in the main one using a iframe like this
<iframe src="XXX.html" width="0" height="0"></iframe>When the user clicks the next button, you have to write 2 HTML this time.. The second one(XXX.html) would have the following code now
<body>
<script>
parent.window.location.reload();
</script>
</body>Just confirm the 'parent' one.. I am not that sure whether its parent or parent_...

Open an html file inside spry collapsible panel

Greetings,
Using CS5
Does anyone know the CSS code/possibility of opening an html file inside the Spry panel?
I've tried the following code:
.CollapsiblePanelContent {
background-image: url(lookoutgraph.html);
Is there a better CSS element for calling up an html file?
For what it's worth...the html file I'm tring to open uses a <canvas> tag. When opened by itself, the html file has no problem opening and displaying the canvas data.
Much Thanks!

With the exeption of images, to add external content to a document you will need to make use of either serverside or clientside code.
Have a look at the SpryHTMLPanel here http://labs.adobe.com/technologies/spry/samples/htmlpanel/html_panel_sample.html
Otherwise, please supply a link to your site so that we can come up with alternatives.

Opening a pdf file through form 10g

Dear all,
I have requirement to open a pdf file through my form application.
Ho will i do this?
What is the procedure to do this??
Please help me.
Regards

Can you tell me where the pdf can be found. Through a webserver or inside the database or is the pdf somewhere else?
If the pdf is available through an url you could use web.show_document which can open the url/pdf document in a new browser window.
If the pdf is inside the database you could download the pdf to the client using webutil and then open the pdf document using a host command.
If the pdf is inside the database or by a url you can also use a forms bean. I've used forms bean bean to unload a pdf from the database and show it inside the forms application. Most important when using a forms bean is that the bean component can show all the fonts which are used inside the pdf. There are some free solutions which can not show i.e. bar codes. The are also some paid components which will do the trick.
Regards,
Mark

Open my html file and cannot edit it

When I open my html file from Flash, in view design all I get is a grey box with the Flash symbol in the middle and no html tools.
I want to link some of my buttons but if I go into view live I get html tools but I still can't access them to make links.
How do I get my html page so that I can make my links?
Forrest

Your next button can still do that. But it has to be programmed within Flash. Flash files are not natively handled by Dreamweaver. You have to export them in order to place them on a website within Dreamweaver.
The only way that Dreamweaver can do this for you is if you create a button in Dreamweaver which does this action for you outside of the Flash area. Then this button can link to another page or Flash file. But if the button resides within the Flash file then it must be edited with Flash.

Help Needed in opening a HTML File from swing application

Hi,
I am opening a HTML file in Internet Explorer from my swing application.
I am using the code given below
private final static String WIN_FLAG = "url.dll,FileProtocolHandler";
private final static String WIN_PATH = "rundll32";
String cmd = WIN_PATH + " " + WIN_FLAG + " " + url;
// url is HTML file Path
Process p = Runtime.getRuntime().exec( cmd );
The HTML file is opening up,but it always opens behind the swing application,that makes me every time to maximize the HTML file after it being opened up.
I want to open it in front of the Swing Application.
Any Help Please ?

Check your Application's JFrame properties (may be ur Frame is set to be in top position ,always),and also check running your application in some other OS.

How do I Open an HTML file for iOS?

How do I open an HTML file for iOS using acrobat?

This is a forum for Adobe Reader for iOS. Acrobat doesn't run on iOS. You need to run it on a Mac or Windows computer. In Acrobat, you can choose File > Create > PDF from Web Page to do what you want. You cannot do that in iOS.

Opening an HTML file stored locally

Hello fellows,
Is it possible to open a locally stored HTML file using Acro javascript?
If, yes, how to make Acrobat/Reader open the HTML file only once, when the rights-enabled PDF is opened for the 1st time?
Thank you for your responses in advance!

Reader cannot open HTML files even manually. You can use JavaScript in Acrobat to convert an HTML file to PDF, but only from a privileged context: http://livedocs.adobe.com/acrobat_sdk/11/Acrobat11_HTMLHelp/JS_API_AcroJS.89.164.html

How do I reinstall iWeb 3.0.3? I inadvertently opened an html file of my website and tried to open it with iWeb '09. I get a message saying "Can't open file" etc., etc. I've tried reinstalling the updated version. Iweb will not open.

How do I reinstall iWeb 3.0.3? I inadvertently opened an html file of my website and tried to open it with iWeb '09. I get a message saying “Can’t open file” etc., etc. I’ve tried reinstalling the updated version. Iweb will not open.

Delete the iWeb preference file, com.apple.iWeb.plist, that resides in your Home/Library/Preferences folder. Then launch iWeb and see if it opens.
What happened was trying to open the html file reset the file path that iWeb saves in its preference file to tell it where to go when you launch iWeb. Deleting the pref file and launching iWeb creates a new file and iWeb looks in your Users/Home/Library/Application Support/iWeb folder for the Domain.sites2 file it uses to create your site.

when opening an HTML file recently my Firefox automatically opens up a yahoo search screen and the file, the entire file name and route for the file is searched for online. I don't even use Yahoo Search i use Google but that doesn't mater have to open the file manually with searching it on on the open screen to read it because it's trying to search for it online instead of reading it from where i clicked on it.

Please read this article about restoring bookmarks:
http://kb.mozillazine.org/Lost_bookmarks
As far as your passwords are concerned, I don't think there's anything you can do. But for the future, you can use the following add-ons to avoid any future loss:
https://addons.mozilla.org/en-US/firefox/addon/2848/
or
http://www.xmarks.com/
Both are good.
And a simple way to import your bookmarks (since you already saved it on your desktop as html) is:
Bookmarks / Organized Bookmarks / Import and Export
Good luck.

Opening local .html files on iPad

I have created a personal homepage that I have loaded on my Macs at home. Any way I can use this file on my iPad 3?

It is possible to open local HTML files in Safari on iPad2. Easy!
Open your Safari.
Touch Bookmark icon for a little while.
A dialogue box appears with "/var/Mobile" title.
Go to "Applications" > your app (iFile, GoodReade or whatever yours) > Documents.
And you are there. Open your HTML files.
Now you can go anywhere to and fro without problem.
It is FTP:///.
If need later, Bookmark that.
With Loving-Kindness!

I have opened two versions of Firefox (v3.6.18 and v3.5), v3.6.18 is my default browser. The problem comes after an attempt to open a HTML file.

I have opened two versions of Firefox (v3.6.18 and v3.5), v3.6.18 is my default browser. The problem comes after an attempt to open a HTML file. An error appears: "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." Why wouldn't it just open on my default browser? Thanks for the help!

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, maybe after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.
