Open a html page from an applet

Hi,
I would like to open, from an applet, an HTML page in a new window with a specific width an eight.
Who can help me ?

Here is an example of applet to javascript with liveconnect:
http://www.narhari.com/java/applet2javascript/
You can use the send(String) method from the sample applet to send something like:
window.open('xyz.html','myPopup','width=200,height=200');in order to open a window with specific dimensions
of course you can also build HTML in your applet and use send() + some javascript to render it.

Open an *.html page from a vi

Hi,
I don't know how to open an .html file from a boolean bouton.
someone could help me ?
thanks

But the HTML file on the RIO (if it's anything like remote front panels on the PC) is only a "pointer" to the VI. It is only used so that the browser will have a place to start. The PC has nothing actually running on it and the RIO is not displaying the web page.
Here is the basic text from a sample file which tells the web browser to connect to a running VI.
http://www.ni.com/webappdemos/lv">>
You can see that it's only a few lines telling the browser to connect to the VI. I think that to use the link you will either need an LV program running on the computer or you will need to write your own browser for the RIO (not a recommended solution).
Is all right, I know that the html file make only a connection to the VI, but the the web page file are on the cRIO.So I don't understand because you think that the browser must start from the cRIO. If I actually can visualize an html file, that is on the cRIO, and the browser are running on my pc, why a link from the VI (as www.html.it) must open a browser on the cRIO and not on client PC?

Open HTML page from the stage

How can I open a HTML page by pressing a button on the stage?
I've created a rollover button and I'm trying to make it open
an existing html page from the local disk (not an internet URL).
But I can't make it open with Lingo or behaviour.
Please help.
Thanks a lot.
Gideon.

goToNetPage "
http://somewhere.html" is the
typical form for a page on
the web, director must use the address format the system's
browser uses
for local files, this is somewhat platform dependant, a
practical
aproach is to open the file in question from within your
browser then
copy and paste the displayed address into your lingo code.
Some report the goToNetPage counterpart provided by the
buddyAPI xtra
works more reliably, the xtra can be used for free if limited
to a
couple of functions.
An alternate approach buddyAPI can use is to have the browser
directly
access the html file as if it were double clicked in the file
manager
using the same form commonly used to open PDF files with
acrobat.
(sorry I don't have example code handy)

Opening a web page in an applet

Some may recognize this as I have posted it before and got nowhere. So I decided to post it again to see if anybody could help me. I have made a few changes to my code, but no guarantees it's better.
public class FinalWindow extends Applet
     private AppletContext appContext;
     public void init()
          java.net.URL url;
          appContext = this.getAppletContext();
          try
               url = new java.net.URL("http://www.google.com");
          } catch (Exception e)
             System.out.println("Didn't work.");
             url = null;
        System.out.println("this");
        try
        if(url != null)
             getAppletContext().showDocument(url, "_self");
               //appContext.showDocument(url, "_self");
        } catch (Exception e)
             System.out.println("Error loading page.");
     public static void main(String[] args)
          FinalWindow fw = new FinalWindow();
          fw.init();
}I have to things that i tried to use to show the web page in the applet, but they both produce NPE saying:
Exception in thread "main" java.lang.NullPointerException
    at java.applet.Applet.getAppletContext(Applet.java:187)
    at FinalWindow.init(FinalWindow.java:84)
    at FinalWindow.main(FinalWindow.java:107)Let me know what ya'll think.

No, I don't want the page to load in the browser window, I want it to load in the applet, as I said before.Your showDocument commands above would result in the target page replacing the page the applet is in, rather than opening the target page inside the applet.
To load a document inside the applet, might be achieved by using a JEditorPane to contain the HTML, then simply calling JEP.setPage(URL). Two things about that though:
1) An applet will need to be trusted in order to load documetns from foreign hosts.
2) Google frowns upon people reading their pages into any bot or software other than a standard browser.
I defined the main() method because that is the way I know how to do it. I'm not worried about having a main() in it right now. You should be. Combined applet/applications do make some sense during development - I do them quite often. But you need to realise that an applet launched that way will not be able to use the kind of things an embedded applet can normally expect to be able to access, such as the AppletContext. (1)
..I just can't figure out how to load a web page in an applet.
Basically making a web browser out of an applet that loads the page I tell it to in the code.JEditorPane (with a HyperlinkListener), trusted applet, not Google. And in fact, though the JEP is getting better over time, it is not generally considered to be good enough to use as the basis for a 'real world (wild web)' browsing component.
Edit 1:
(1) Having implemented a basic AppletContext for Appleteer , I can tell you it is not trivial!
Also, that code above was just one line short (the import for the applet package) of being an SSCCE *(<- link).* Please consider posting SSCCEs in future - you get better chance of help, faster.

Opening an HTML popup from Flash, not as tab

Hi
I need to open an HTML popup from Flash (using ActionScript in
Flex 4).
Thus far I found a solution, and it does work in Safari - a new
and separate HTML window is popped up (with a new web page).
private function popUpTheHtmlEditor():void {
var url:String = "http://www.adobe.com";
var request:URLRequest = new URLRequest(url);
try {
    navigateToURL(request, '_blank');
} catch (e:Error) {
    trace("Error occurred!");
But in (my) Firefox (with my settings), when I click on the Flash
(Flex) button, the page is being opened in a new tab.
I need a solution which pops up the HTML page in a new/separate
window, as far as possible regardless of the browser (and browser
settings).
I found an example where a popup is opened from HTML, and it opens a
separate window (a real popup) in my Firefox:
http://www.gtalbot.org/FirefoxSection/Popup/PopupAndFirefox.html
-> "Open a requested popup"
The JavaScript code seems to be:
OpenRequestedPopup(this.href, this.target); return false;
with this function def:
function OpenRequestedPopup(strUrl, strTarget)
    if (WindowObjectReferenceOfRequestedPopup == null || WindowObjectReferenceOfRequestedPopup.closed)
    WindowObjectReferenceOfRequestedPopup = window.open(strUrl, strTarget, "top=" + windowTop + ",left=" + windowLeft + ",width=" + windowWidth + ",height=" + windowHeight + ",menubar,toolbar,location,resizable,scrollbars,status");
    else
    if(WindowObjectReferenceOfRequestedPopup.focus)
      WindowObjectReferenceOfRequestedPopup.focus();
How could I call such code from ActionScript? Should this work through
ExternalInterface? I couldn't even get this to work:
ExternalInterface.call('alert', 'foo');
Should I use swfobject.js for embedding the .swf in the HTML wrapper?
Any other ideas?
The two files are pasted below.
Here's the compiler command I'm using:
mxmlc -output button.swf -target-player 10.0.0 flash_to_editor.mxml
I'm running the examples locally (as files, not over http). Would it
help to place the files on a server?

Hi,
Here's a solution.
1. Make ExternalInterface work when files are loaded as local files:
Go to
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.htm l
In tab Global Security Settings: Edit Locations -> Add Location ->
browse to the .swf file, add it. Make sure it's in the list (under the
Edit Locations drop down, with a green check mark.)
Now open the HTML wrapper in a browser (eg Firefox).
Now this works (ActionScript):
private function popUpTheHtmlEditor():void {
ExternalInterface.call('alert', 'foo');
On Windows: perhaps:
http://techjig.blogspot.com/2008/03/flash-global-security-settings-windows.html
"In order for external interface functions to be called, you must also
specify the folder/file where the swf file is located."
The above setup isn't necessary when the files are on a server.
Also see:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/external/External Interface.html#call()
""ExternalInterface" "
"call() method"

"Using the ExternalInterface API to access JavaScript"
2. Open a real popup: Example:
ActionScript:
private function popUpSomething():void {
var editorPathOrUrl:String =
    'wrapper.html';
var windowName:String =
    "SomeNameSeeDocs";
var windowFeatures:String =
    "toolbar=yes,menubar=yes,location=yes,scrollbars=yes,resizable=yes,width=500,height=700";
ExternalInterface.call(
    'launch',editorPathOrUrl,windowName,windowFeatures
JavaScript:
function launch(editorPathOrUrl,windowName,windowFeatures) {
windowRef = window.open(
    editorPathOrUrl,windowName,windowFeatures
Works in all browser I tested except Opera.

Replace HTML page with an applet

Hello to everybody!
I created a servlet who can manage file upload from an HTML page.
Now I want to replace that HTML page with an applet.
I know that I need to use multipart/form-data , but I have no experience with applet.
HTML page code is:
<html>
<head><title>Upload</title></head>
<body>
<FORM ACTION="http://localhost:8080/examples/servlets/servlet/UploadTest" ENCTYPE="multipart/form-data" METHOD=POST>
What is your name? <INPUT TYPE=TEXT NAME=submitter> <BR>
Which file do you want to upload? <INPUT TYPE=FILE NAME=file> <BR>
<INPUT TYPE=SUBMIT>
</FORM>
</body>
</html>
Any help for "translating" this html page into an applet?
Applet will send, like html page, a string and a file.
Thanks in advance, Liuk

If you use something like Apache Http Client you dont have to do any low level implementations.
Also if you are the one who is writing both servlet and applet you dot have to stick to standerd formats. you can develop your own format and write both servlet and applet to handle it. that kind of thing can be done easily even with URLConnection. But if you plan to send large files then URLConnection may not be the right option becouse I have seen many complaining that URLConnection gives OutOfMemoryErrors when uploading large amounts of data.
