How can I open a URL from BlackBerry ?
in J2ME I am using:
this.platformRequest("http://www.google.com");
How can I do this on BlackBerry?
If you want to launch a browser session you would use:
Browser.getDefaultSession().displayPage("http://www.google.com");
If you want to open, and then read the returned data for processing yourself:
HttpConnection google = (HttpConnection)javax.microedition.io.Connector.open("http://www.google.com");
int rc = google.getResponceCode();
...
InputStream is = google.openInputStream();
You do need to make sure that processing the connection and returned data does not happen on the event thread or your blackberry will hang.
Browser.getDefaultSession().displayPage("http://www.google.com");
is the correct way to launch the BlackBerry browser with your URL.
well i think kozen is right but u can go ahead like this,may be......
BrowserSession bSession = Browser.getDefaultSession();
bSession.displayPage(url);
BrowserSession myBrowser = Browser.getDefaultSession();
myBrowser.displayPage("http://www.stackoverflow.com");
or
Browser.getDefaultSession().displayPage("http://www.stackoverflow.com");

I am playing a list of audios in an html into UIWebView of IOS with the AudioContext object of the Javascript
eg :
var ctx = new AudioContext();
var node= ctx.createBufferSource();
node.buffer = AudioBufferFromAjaxCall;
node.connect(gainNodeObjCreatedEarlier);
node.start();
and the problem is node.stop(); isnt working , the audio started continuesly playing and not stopping
It would be helpful to know the version of safari that your UIWebView is using and whether or not you can reproduce it in the desktop version. Also, do you get any kind of log or error in the console?
In any case, have you tried passing a parameter to the stop method? something like
node.stop(0);
This argument specifies after how many seconds the node should stop. Sending 0 may help.
I am running Win10 IoT on a pi 2. I need to be able to take pictures that are focused but cannot get the focus working. The application is a background app so I don't have a way of previewing the camera on a display. Is there any way of doing this? Currently I have
await _mediaCapture.StartPreviewAsync();
_mediaCapture.VideoDeviceController.FocusControl.Configure(new FocusSettings
{
Mode = FocusMode.Continuous,
WaitForFocus = true
});
await _mediaCapture.VideoDeviceController.FocusControl.FocusAsync();
await _mediaCapture.CapturePhotoToStreamAsync(ImageEncodingProperties.CreateJpeg(), stream);
await _mediaCapture.StopPreviewAsync();
but I am getting the error
WinRT information: Preview sink not set
when I try to focus. All of the examples I've seen online show that the preview is output to a control and I assume it wires a sink up automagically. Is there a way to do this manually through code? Possibly without the preview?
I wonder if the code may work even without FocusControl.
I propose you follow Customer Media Sink implementation example and use of StartPreviewToCustomSinkIdAsync method described at http://www.codeproject.com/Tips/772038/Custom-Media-Sink-for-Use-with-Media-Foundation-To
I didn't find a way to do this. I ended up converting the background app to a UI app with a Page containing a CaptureElement control in order to preview and focus.
Instead of adding a UI, just create a CaptureElement and set the source to the _mediaCapture before calling await _mediaCapture.StartPreviewAsync();
Something like:
_captureElement = new CaptureElement { Stretch = Stretch.Uniform };
_mediaCapture = new MediaCapture();
await _mediaCapture.InitializeAsync(...);
_captureElement.Source = _mediaCapture;
await _mediaCapture.StartPreviewAsync();
This may be a simple one but I can't figure it out. How can I open a web page in the main browser from extendscript as I would do with window.open() in Javascript?
I am targeting After Effects and would like it to work on both OS X and Windows.
In After Effects you can simply do it using the system object, as Dirk mentioned. However you need several things for that:
checking that the script can access the network:
if (app.preferences.getPrefAsLong("Main Pref Section", "Pref_SCRIPTING_FILE_NETWORK_SECURITY") != 1)
{
alert("Please tick the \"Allow Scripts to Write Files and Access Network\" checkbox if Preferences > General");
// Then open Preferences > General to let people tick the checkbox
app.executeCommand(2359);
// Here you should check again if they ticked it, and choose to continue or stop ...
}
checking of the OS:
var os = system.osName;
if (!os.length)
{
// I never remember which one is available, but I think $.os always is, you'll have to check
os = $.os;
}
app_os = ( os.indexOf("Win") != -1 ) ? "Win" : "Mac"
os-dependent system calls:
var url = "http://aescripts.com";
if ( app_os == "Win" )
{
system.callSystem("explorer " + url);
}
else
{
system.callSystem("open " + url);
}
Provided you have access to CSInterface.js:
cep.util.openURLInDefaultBrowser("http://www.google.com")
One application independent way is to write an operating system's representation of the URL into a file, then execute() the file.
On the Mac that would be a .webloc file. The underlying format is "plist binary", if you prefer to generate xml, create a sample webloc by drag&drop from the browser address and convert it:
plutil -convert xml1 ~/Desktop/sample.webloc
To invoke that webloc, run the ExtendScript
File("~/Desktop/sample.webloc").execute()
You can do anything on your local computer - commandline and anything else in a VBS file, and you can launch a vbs file from javascript like this:
function RunScriptVBS(whatscriptname){
app.doScript(File(whatscriptname), ScriptLanguage.VISUAL_BASIC);
}
Here is your vbs script:
Dim objShell
Set objShell = CreateObject("WScript.shell")
objShell.Run ("http://www.somewhere.com")
set objShell = nothing
The scope of the question apparently has been refined to After Effects (AE), so I add another answer specific to that application.
On my Machine AE CS6 does not produce an object model file for display by the ExtendScript Toolkit. Please retry it yourself, the object model viewer is in the help menu of ESTK.
Anyway, the ESTK data browser does works. If you target AE, you'll see a couple of objects and classes. Eventually check some more menu items in the databrowser panel flyout menu. I had a deeper look at the app object itself (no openUrl() there) and also found a "system" object. Expand that and you see several interesting methods.
The following script opens a URL on the Mac. I have not tried Windows, maybe it is even the same.
system.callSystem("open http://www.google.com")
As this is the first time I launched AfterEffects, I might have missed better ways.
I would like to create a simple add-on that would play a different MP3 recording every time the user double clicks a word in a webpage he is visiting and selects a special option from the context menu.
The MP3 files are located on a remote server. Normally I would use JavaScript+Flash to play the MP3 file. In a Firefox add-on, however, I'm unable to load external scripts for some reason (playing the sound works fine if it's the webpage itself that loads the scripts, but of course I need it to work with every website and not just the ones that include the script).
So what's the easiest way to play a remote MP3 file in a Firefox add-on using JavaScript?
This may not entirely solve your question, as I don't BELIEVE it plays MP3s, but I'm not certain.
Firefox has nsISound, which I KNOW can play remote WAV files, as I've tested and proved it.
You may want to test it for yourself and see if it leads you a little closer!
var ios = Components.classes['#mozilla.org/network/io-service;1'].getService(Components.interfaces.nsIIOService);
var sound = ios.newURI("http://www.yoursite.com/snds/haha.wav", null, null);
var player = Components.classes["#mozilla.org/sound;1"].createInstance(Components.interfaces.nsISound);
player.play(sound);
Good luck, I hope this at least gets you close!
I know this is an old question, but if someone needs a way to do it:
let player = document.createElement("audio");
player.src = browser.runtime.getURL(SOUND_URL);
player.play();
There is one caveat: the user must have allowed autoplay on the website.
Here is a working code....
var sound = Components.classes["#mozilla.org/sound;1"].createInstance(Components.interfaces.nsISound);
var soundUri = Components.classes['#mozilla.org/network/standard-url;1'].createInstance(Components.interfaces.nsIURI);
soundUri.spec = "chrome://secchat/content/RING.WAV";
sound.play(soundUri);
var window = require('sdk/window/utils').getMostRecentBrowserWindow();
var audio = ('http://example.com/audio.mp3');
audio.play();
I'm developing an applications which I've got running on a server on my linux desktop. Due to the shortcomings of Flash on Linux (read: too hard) I'm developing the (small) flash portion of the app in Windows, which means there's a lot of frustrating back and forth. Now I'm trying to capture the output of the flash portion using flash tracer and that is proving very difficult also. Is there any other way I could monitor the output of trace on linux? Thanks...
Hope this helps too (for the sake of google search i came from):
In order to do trace, you need the debugger version of Flash Player from
http://www.adobe.com/support/flashplayer/downloads.html (look for "debugger" version specifically - they are hard to spot on first look)
Then an mm.cfg file in your home containing
ErrorReportingEnable=1 TraceOutputFileEnable=1 MaxWarnings=50
And then you are good to go - restart the browser. When traces start to fill in, you will find the log file in
~/.macromedia/Flash_Player/Logs/flashlog.txt
Something like
tail ~/.macromedia/Flash_Player/Logs/flashlog.txt -f
Should suffice to follow the trace.
A different and mind-bogglingly simple workaround that I've used for years is to simply create an output module directly within the swf. All this means is a keyboard shortcut that attaches a MovieClip with a textfield. All my traces go to this textfield instead of (or in addition to) the output window. Over the years I've refined it of course, making the window draggable, resizable, etc. But I've never needed any other approach for simple logging, and it's 100% reliable and reusable across all platforms.
[EDIT - response to comment]
There's no alert quite like javascript's alert() function. But using an internal textfield is just this simple:
ACTIONSCRIPT 1 VERSION
(See notes at bottom)
/* import ExternalInterface package */
import flash.external.*;
/* Create a movieclip for the alert. Set an arbitrary (but very high) number for the depth
* since we want the alert in front of everything else.
*/
var alert = this.createEmptyMovieClip("alert", 32000);
/* Create the alert textfield */
var output_txt = alert.createTextField("output_txt", 1, 0, 0, 300, 200);
output_txt.background = true;
output_txt.backgroundColor = 0xEFEFEF;
output_txt.selectable = false;
/* Set up drag behaviour */
alert.onPress = function()
{
this.startDrag();
}
alert.onMouseUp = function()
{
stopDrag();
}
/* I was using a button to text EI. You don't need to. */
testEI_btn.onPress = function()
{
output_txt.text = (ExternalInterface.available);
}
Notes: This works fine for AS1, and will translate well into AS2 (best to use strong data-typing if doing so, but not strictly required). It should work in Flash Players 8-10. ExternalInterface was added in Flash 8, so it won't work in previous player versions.
ACTIONSCRIPT 3 VERSION
var output_txt:TextField = new TextField();
addChild(output_txt);
output_txt.text = (String(ExternalInterface.available));
If you want to beef it out a bit:
var alert:Sprite = new Sprite();
var output_txt:TextField = new TextField();
output_txt.background = true;
output_txt.backgroundColor = 0xEFEFEF;
output_txt.selectable = false;
output_txt.width = 300;
output_txt.height = 300;
alert.addChild(output_txt);
addChild(alert);
alert.addEventListener(MouseEvent.MOUSE_DOWN, drag);
alert.addEventListener(MouseEvent.MOUSE_UP, stopdrag);
output_txt.text = (String(ExternalInterface.available));
function drag(e:MouseEvent):void
{
var alert:Sprite = e.currentTarget as Sprite;
alert.startDrag();
}
function stopdrag(e:MouseEvent):void
{
var alert:Sprite = e.currentTarget as Sprite;
alert.stopDrag();
}
[/EDIT]
If you only need the trace output at runtime, you can use Firebug in Firefox and then use Flash.external.ExternalInterface to call the console.log() Javascript method provided by Firebug.
I've used that strategy multiple times to a large degree of success.
Thunderbolt is a great logging framework with built-in firebug support.
I use the flex compiler on linux to build actionscript files, [embed(source="file")] for all my assets including images and fonts, I find actionscript development on linux very developer friendly.
Then again, I'm most interested in that flash has become Unix Friendly as aposed to the other way around :)
To implement FlashTracer, head to the following address and be sure you have the latest file. http://www.sephiroth.it/firefox/flashtracer/ . Install it and restart the browser.
Head over to adobe and get the latest flash debugger. Download and install the firefox version as FlashTracer is a firefox addition.
Now that firefox has the latest flash debugger and flash tracer we need to locate mm.cfg
Location on PC: C:\Documents and Settings\username
Inside of mm.cfg should be:
ErrorReportingEnable=1
TraceOutputFileEnable=1
MaxWarnings=100 //Change to your own liking.
Once that is saved, open firefox, head to the flash tracer window by heading to tools > flash tracer. In the panel that pops up there is two icons in the bottom right corner, click the wrench and make sure the path is set to where your log file is being saved. Also check to see that flash tracer is turned on, there is a play/pause button at the bottom.
I currently use this implementation and hope that it works for you. Flash Tracer is a little old, but works with the newest versions of FireFox. I am using it with FireFox 3.0.10.
