I have one .fla file sent by some one. I want to import this file into my actionscript project using flex builder and I need to work on frames of the fla file . How to do this. I am very new to flex . I am searching this in internet with of no results. please help me.
You cannot edit a flash file directly within the Flash Builder (i.e. Flex) IDE. You can however access the published swf from within Flex.
A common use is to access assets from a library swf - http://www.bit-101.com/blog/?p=853. But I assume you are interested in accessing specific frames in the interactive. Different options are possible :
use localConnection - http://fbflex.wordpress.com/2008/06/12/passing-data-from-flash-to-flex-and-back/
load the resulting swf into a loader object and navigate to frame - SWFLoader starts to play SWF without the loading being complete
load the resulting swf into a loader object and communicate via events
<mx:SWFLoader id="embeddedFlash" source="path/to/file.swf" complete="onLoaderComplete(event)"/>
<mx:Script>
<![CDATA[
private function onLoaderComplete(event:Event)
{
// the swf file needs to be fully loaded before these calls are made
if(embeddedFlash.content)
{
// 2 - navigate to frame
var mc:MovieClip = MovieClip(embeddedFlash.content);
mc.gotoAndPlay(0);
// 3 - communicate via events
embeddedFlash.content.addEventListener("nextButtonClick", onNextClick);
embeddedFlash.content.dispatchEvent(new Event("changeOptions", {/* pass on data */}));
}
}

I have a default website in my IIS where I have created one virtual directory "wsdls".
I would want to gather statistics on how many requests are triggered to my virtual directory. This would need a request interception at web server level and gather statistics. "HTTPModule" was one of the many solutions I have considered which is suitable for such scenario. Hence I have started building one.
For testing purpose, I wanted to create a HTTP Module and apply it on a particular extension files (say *.wsdl) and on every GET request of any .wsdl files in this virtual directory, I will want to redirect the application to "www.google.com". This would demonstrate a good example of how HTTP Module can be used and deployed on IIS.
HTTPModule which is written using Visual Studio is shown below,
namespace Handler.App_Code
{
public class HelloWorldModule : IHttpModule
{
public HelloWorldModule(){
}
public String ModuleName{
get { return "HelloWorldModule"; }
}
// In the Init function, register for HttpApplication
// events by adding your handlers.
public void Init(HttpApplication application){
application.BeginRequest +=
(new EventHandler(this.Application_BeginRequest));
application.EndRequest +=
(new EventHandler(this.Application_EndRequest));
}
private void Application_BeginRequest(Object source,
EventArgs e)
{
// Create HttpApplication and HttpContext objects to access
// request and response properties.
HttpApplication application = (HttpApplication)source;
HttpContext context = application.Context;
context.Response.Redirect("www.google.com");
}
private void Application_EndRequest(Object source, EventArgs e)
{
//Nothing to be done here
}
public void Dispose() { }
}
}
Now I have done a build of this project for x64 version and I am able to browser successfully the "dll" file. Now I have to register this dll in IIS and whenever I try to access the *.wsdl files, the requests automatically divert to "www.google.com". Here is the next step I have done,
Then I have enabled the Handler mappings as shown below,
I am assuming that is it!! Nothing more to be done. I should be able to intercept the requests for all HTTP requests which are of the form "*.wsdl". This means whenever I access any wsdl from the server, control should be going back to google(Because of the logic written in begin request ). But unfortunately, I failed in achieving it. What can be done here?
One thing I noticed is that when you are trying to redirect to an external URL use
http://
So change
context.Response.Redirect("www.google.com");
to
context.Response.Redirect("http://www.google.com", true);
I could solve the problem what I am facing and below are the observations which were missing in my understanding and which helped me in solving my problem:
Locating proper web.config file :
Every website in IIS will be having a web.config file to have control over the application.
Since I am working with "Default Website", this refers to the directory "C:\\inetpub\\wwwroot"
There will be a "web.config" file which would be present in this director. Please create it if not already present.
Modifying web.config :
Once you have identified the file which needs to be modified, just add necessary module configuration to web.config
In this case, we would want to add a Module to the default website, the probably setting would be shown below,
Adding contents to bin directory :
Now if you try to run the application, the IIS would not find any dll or executable to run and hence we would need to keep the executables at a particular location.
Create a director if not already present with the name "bin" at the root of the directory and place all the dlls which you would want this website to execute. Sample shown below,
General Points to be considered:
Proper access must be given for the folder which consists of dll.
It is ideally not suggested to modify the entire website. It would be ideal if one works only on their web application.
If web.config is not found, we can create one.
If bin is not present in the web root directory, we can create one.
I'm using the QT WebEngine framework to display web pages. I'm injecting javascript into a page when it loads, and want to allow the javascript to be able to access a QT object. Apparently, to do this a QWebChannel must exist that establishes some IPC between chromium (the javascript) and the rest of my C++/QT project. I came across the QWebEnginePage::setWebChannel (QWebChannel *channel) function, however I can't find any examples of its use. The documentation (http://doc.qt.io/qt-5/qwebenginepage.html#setWebChannel) mentions that qt.webChannelTransport should be available in the javascript context, but I don't see where that is established in qwebchannel.js (https://github.com/qtproject/qtwebchannel/blob/dev/src/webchannel/qwebchannel.js). I've seen the WebChannel examples (http://doc.qt.io/qt-5/qtwebchannel-examples.html) and would like to avoid WebSockets if possible.
Below is how I tried to implement the web channel.
Whenever a page loads I establish a channel and inject the javascript in C++:
QWebChannel *channel = new QWebChannel();
channel->registerObject(QStringLiteral("jshelper"), helper);
view->page()->runJavaScript(qwebjs); //this is qwebchannel.js
view->page()->setWebChannel(channel);
view->page()->runJavaScript(myfunction); //function that calls QT object (jshelper)
In Javascript:
new QWebChannel(qt.webChannelTransport, function(channel) { ... });
Which results in the channel not being connected properly (assuming this is because of qt.webChannelTransport, as it was working when I was using WebSockets). Any pointers to examples of QWebChannel being set up with QWebEnginePage this way is also appreciated.
Short answer: add <script type="text/javascript" src="qrc:///qtwebchannel/qwebchannel.js"></script> to your html page (before you call new QWebChannel of course), and remove the line view->page()->runJavaScript(qwebjs); //this is qwebchannel.js from your C++ code.
Long answer:
I too had a ton of trouble figuring out how to use QWebChannel without WebSockets correctly -- managed to get it working after digging around in Qt 5.5 source code and mailing lists (documentation is still lacking). Note that this only works with the new Qt 5.5.
Here's how to use QWebChannel:
// file: MyWebEngineView.cpp, MyWebEngineView extends QWebEngineView
QWebChannel *channel = new QWebChannel(page());
// set the web channel to be used by the page
// see http://doc.qt.io/qt-5/qwebenginepage.html#setWebChannel
page()->setWebChannel(channel);
// register QObjects to be exposed to JavaScript
channel->registerObject(QStringLiteral("jshelper"), helper);
// now you can call page()->runJavaScript(...) etc
// you DON'T need to call runJavaScript with qwebchannel.js, see the html file below
// load your page
load(url);
And on the JS side:
<!-- NOTE: this is what you're missing -->
<script type="text/javascript" src="qrc:///qtwebchannel/qwebchannel.js"></script>
<script type="text/javascript">
<!-- it's a good idea to initialize webchannel after DOM ready, if your code is going to manipulate the DOM -->
document.addEventListener("DOMContentLoaded", function () {
new QWebChannel(qt.webChannelTransport, function (channel) {
var jshelper = channel.objects.jshelper;
// do what you gotta do
});
});
</script>
Also make sure you've added QT += webenginewidgets webchannel to your .pro file else this won't build!
Bonus: you can debug your JavaScript from the comfort of Chrome Dev Tools now! Just add this somewhere in your Qt code (ideally in your application startup):
#ifdef QT_DEBUG
qputenv("QTWEBENGINE_REMOTE_DEBUGGING", "23654");
#endif
Then start your application, navigate to http://localhost:23654 in Chrome, and you'll get a fully-functional JS debugger, profiler, console, etc :)
Follow-up (19/04/2016): if your remote debugger isn't working, note that the qputenv call must also occur before any calls to QWebEngineSettings or any other WebEngine-related class, because these trigger the WebEngine "zygote" process immediately (the zygote is the parent QtWebEngineProcess from which all future QtWebEngineProcesses are forked) and then qputenv cannot affect it. Spent a few hours tracking this down.
I'm stuck with an issue that I'm gonna try and explain clearly. I'm using a gtkmm webkit browser in a sort of embedded application to access php/html files. The point is that I fail to code a way for this webkit to handle downloads.
Oh, and I'm coding in C++.
The file to download currently looks like below in my HTML code :
<a href='excel/template_users.php'><img src='imgs/excelbis.png'/>Download Excel File</a>
The "template_users.php" file is just a way of forcing the user to download the file (you can also access to the website via a "classic" web browser). It contains only :
<?php
header("Content-disposition: attachment; filename=template_users.xls");
header("Content-type: application/vnd.ms-excel:");
readfile("template_users.xls");
?>
I've been trying to handle downloads by adding to my IntegratedBrowser class constructor (which instantiate the webkit) a connector to the signal "download-requested" :
gboolean ret = FALSE;
g_signal_connect(webView, "download-requested", G_CALLBACK(&IntegratedBrowser::downloadRequested), &ret);
And the associated method :
gboolean IntegratedBrowser::downloadRequested(WebKitWebView* webView, WebKitDownload *download, gboolean *handled)
{
const gchar* dest = webkit_download_get_uri(download);
webkit_download_set_destination_uri(download, dest);
return FALSE;
}
I should precise that everything runs of course fine when I'm trying to download the file via a "classic web browser". The c++ code compile smoothly, however, nothing happens when I click on the link using the webkit. I would like the file to be downloaded in a location chosen by the user if possible (downloading the file into a specific location is viable as well) when clicking on the link.
Have you got any idea of what I am doing incorrectly ?
Thanks for your answers !
Edit : now my downloadRequested method looks like that :
gboolean IntegratedBrowser::downloadRequested(WebKitWebView* webView, WebKitDownload *download, gboolean *handled)
{
const gchar* dest = g_strdup_printf("%s", "file:///home/user/test.xls");
webkit_download_set_destination_uri(download, dest);
return TRUE;
}
The return FALSE from your IntegratedBrowser::downloadRequested() method cancels the download. return TRUE should start it.
Also, you are getting the URI that you are downloading with webkit_download_get_uri() (e.g. http://my.website.com/myfile.jpeg) and setting that to be the destination URI. Set the destination URI to point to a local file instead (although leaving it unset probably downloads the file to a default location.)
If you want a file selector for choosing where to save the download, use GtkFileChooser and when you are done with it, retrieve a URI using gtk_file_chooser_get_uri().
I need to create a simple web service (being the "server"). The goal is to provide some data I do read in an Qt / C++ application as JSON data. Basically a JavaScript application in the browser shall read its data from the Qt app. It is usually a single user scenario, so the user runs a Google Maps application in her browser, while additional data come from the Qt application.
So far I have found these libs:
Qxt: http://libqxt.bitbucket.org/doc/0.6/index.html but being a newbie on C++/Qt I miss some examples. Added: I have found one example here
gSoap: http://www.cs.fsu.edu/~engelen/soap.html has more examples and documentation and also seems to support JSON
KD SOAP: http://www.kdab.com/kdab-products/kd-soap/ with no example as far as I can tell, docu is here
Qt features itself, but it is more about acting as a client: http://qt-project.org/videos/watch/qt-networking-web-services
Checking SO gives me basically links to the above libs
webservice with Qt with an example I do not really get.
How to Create a webservice by Qt
So basically I do have the following questions:
Which lib would you use? I want to keep it as simple as possible and would need an example.
Is there another (easy!) way to provide the JSON data to the JavaScript Web page besides the WebService?
-- Edit, remarks: ---
Needs to be application intrinsic. No web server can be installed, no extra run time can be used. The user just runs the app. Maybe the Qt WebKit could be an approach....
-- Edit 2 --
Currently checking the tiny web servers as of SO " Qt HTTP Server? "
As of my tests, currently I am using QtWebApp: http://stefanfrings.de/qtwebapp/index-en.html This is one of the answers of Edit 2 ( Qt HTTP Server? )
Stefan's small WebServer has some well documented code, is written in "Qt C++" and easy to use, especially if you have worked with servlets already. Since it can be easily integrated in my Qt project, I'll end up with an internal WebServer.
Some demo code from my JSON tests, showing that generating the JSON content is basically creating a QString.
void WebServiceController::service(HttpRequest& request, HttpResponse& response) {
// set some headers
response.setHeader("Content-Type", "application/json; charset=ISO-8859-1");
response.setCookie(HttpCookie("wsTest","CreateDummyPerson",600));
QString dp = WebServiceController::getDummyPerson();
QByteArray ba = dp.toLocal8Bit();
const char *baChar = ba.data();
response.write(ba);
}
If someone has easy examples with other libs to share, please let me know.
QByteArray ba = dp.toLocal8Bit();
const char *baChar = ba.data();
You don't need to convert the QByteArray to char array. Response.write() can also be called with a QByteArray.
By the way: qPrintable(dp) is a shortcut to convert from QString to char array.
I currently store text to speech mp3 files as varbinary(max) in the database. what I want to do is play those audio files using the embed tag where the source is ashx file that will recieve the id of the database record and write the byte array.
My ashx file has the following code
byte[] byteArray = ttsMessage.MessageContents;
context.Response.Buffer = true;
context.Response.Clear();
context.Response.ClearContent();
context.Response.ClearHeaders();
context.Response.ContentType = "audio/mpeg";
context.Response.OutputStream.Write(byteArray, 0, byteArray.Length);
context.Response.End();
The call from the aspx page is as follows
Panel5.Controls.Add(new LiteralControl(String.Format("<embed src='/TestArea/PreviewWav.ashx?source={0}' type='audio/mpeg' height='60px' width='144px'/>", ttsMessage.Id.ToString())));
I have gotten this to work with the following
Panel5.Controls.Add(new LiteralControl(String.Format("<audio controls='controls' autoplay='autoplay'><source src='/TestArea/PreviewWav.ashx?source={0}' type='audio/x-wav' /></audio>", ttsMessage.Id.ToString())));
Using the audio tag but cannot seem to get it to work with the embed tag.
I am using IE9/VS2010
Any ideas?
I think the wrong thing with embed tag is that...
Embed tag call a plugin like winmediaplayer ocx than handler firstly called from web page than media plugin get the ashx url than it started to call handler.
But web page's request and mediaplayer plugin's requests are diffent so if you check users Authentication or some other header information it fails.
You can easily see that on fiddler utility. On fiddler top-right side shows the request info. there is a user-agent part. Look it carefully.
How many requests happen from your handler,notice them. What are the differs. for each reqs.
If you have this issue,
You may use a ticket system or redirect a safety area for download without header or other request checks. Sadly web page requst cannot complately transfer media player and others.
hope helps
