  • How to scroll the horizontal scrollbar in an iFrame from the parent frame?

    - by Mohammad
    Is there any cross browser way to scroll the horizontal scroll bar of an IFrame with super wide content with Javascript inside the parent frame. Also I need it to be attached to the mouse wheel event. This is what I have so far, it's a bit copy and paste at the moment and doesn't work unfortunately. //var myIframe = document.getElementById('iframeWithWideContent'); //myIframe.onload = function (myIframe) { var mouseWheelEvt = function (e){ var event = e || window.event; if (document.body.doScroll){ document.body.doScroll(event.wheelDelta>0?"left":"right"); }else if ((event.wheelDelta || event.detail) > 0){ document.body.scrollLeft -= 10; }else{ document.body.scrollLeft += 10; } return false; } if ("onmousewheel" in document.body){ document.body.onmousewheel = mouseWheelEvt; }else{ document.body.addEventListener("DOMMouseScroll", mouseWheelEvt); } //}? I probably should uncomment that code, replace document.body with myIframe though I wouldn't know what I'm doing wrong. Demo on JSBIN link fixed Any help from you JavaScript Lords would be very appreciated. Thank you!

  • Hazelcast Distributed Executor Service KeyOwner

    - by János Veres
    I have problem understanding the concept of Hazelcast Distributed Execution. It is said to be able to perform the execution on the owner instance of a specific key. From Documentation: <T> Future<T> submitToKeyOwner(Callable<T> task, Object key) Submits task to owner of the specified key and returns a Future representing that task. Parameters: task - task key - key Returns: a Future representing pending completion of the task I believe that I'm not alone to have a cluster built with multiple maps which might actually use the same key for different purposes, holding different objects (e.g. something along the following setup): IMap<String, ObjectTypeA> firstMap = HazelcastInstance.getMap("firstMap"); IMap<String, ObjectTypeA_AppendixClass> secondMap = HazelcastInstance.getMap("secondMap"); To me it seems quite confusing what documentation says about the owner of a key. My real frustration is that I don't know WHICH - in which map - key does it refer to? The documentation also gives a "demo" of this approach: import com.hazelcast.core.Member; import com.hazelcast.core.Hazelcast; import com.hazelcast.core.IExecutorService; import java.util.concurrent.Callable; import java.util.concurrent.Future; import java.util.Set; import com.hazelcast.config.Config; public void echoOnTheMemberOwningTheKey(String input, Object key) throws Exception { Callable<String> task = new Echo(input); HazelcastInstance hz = Hazelcast.newHazelcastInstance(); IExecutorService executorService = hz.getExecutorService("default"); Future<String> future = executorService.submitToKeyOwner(task, key); String echoResult = future.get(); } Here's a link to the documentation site: Hazelcast MultiHTML Documentation 3.0 - Distributed Execution Did any of you guys figure out in the past what key does it want?

  • displaying video from webcam in OpenCV

    - by Adi
    hi all, I have installed VS2008 and am able to run the demo codes "camshiftdemo and lkdemo " which comes in the opencv library. With this done, now I am trying to run some simple codes from the internet to get acquainted with the OpenCV. I am just trying to display video from webcam and I am getting the following error.. Error I am getting is : Unhandled exception at 0x5e7e3d10 (highgui200.dll) in opencv.exe: 0xC0000005: Access violation reading location 0x719b3856. The code I am trying to run is : include include void main(int argc,char argv[]) { int c; IplImage color_img; CvCapture* cv_cap = cvCaptureFromCAM(-1); // -1 = only one cam or doesn't matter cvNamedWindow("Video",1); // create window for(;;) { color_img = cvQueryFrame(cv_cap); // get frame if(color_img != 0) cvShowImage("Video", color_img); // show frame c = cvWaitKey(10); // wait 10 ms or for key stroke if(c == 27) break; // if ESC, break and quit } /* clean up */ cvReleaseCapture( &cv_cap ); cvDestroyWindow("Video"); } Any help in this will be greatly appreciated.

  • Java - How to detect that the internet connection has got disconnected through a java desktop applic

    - by Yatendra Goel
    I am developing a Java Desktop Application that access internet. It is a multi-threaded application, each thread do the same work (means each thread is an instance of same Thread class). Now, as all the threads need internet connection to be active, there should be some mechanism that detects whether an internet connection is active or not. Q1. How to detect whether the internet connection is active or not? Q2. Where to implement this internet-status-check-mechanism code? Should I start a separate thread for checking internet status regularly and notifies all the threads when the status changes from one state to another? Or should I let each thread check for the internet-status itself? Q3. This issue should be a very common issue as every application accessing an internet should deal with this problem. So how other developers usually deal with this problem? Q4. If you could give me a reference to a good demo application that addresses this issue then it would greatly help me.

  • Trimming bit of the beginning off a recorder waveform

    - by Lowgain
    I've got a flash 10.1 app that lets me record microphone input to a wav without a media server, which I am saving to an Amazon S3 bucket. I have another process running on a server which gets wavs from this bucket, converts to mp3 using LAME and puts them into another bucket. This all works fine, but in converting wav mp3, about 0.1sec or so of silence is added to my sound. In the application this are being used in, perfect sync is critical, so I need to trim off that little bit. If I have to trim it off the original waveform that is okay, I don't expect anything important to happen in that first fraction of a second. What is the best way to go about this? I am using Adobe's WavWriter to convert by ByteArray into a proper waveform. Is there a way I can easily trim off the first few samples from my ByteArray without invalidating the structure? Alternatively, is there a good server-side tool I can use to trim the wav before running it through LAME, or an argument I can give LAME? Or, could I even trim that sound off the mp3 after it has been converted? Thanks!

  • Google Maps API V3: How to jump to a specific marker from outside the map?

    - by Tom
    I have a map with two markers on it. The initial view of the map only shows one marker, and I want to provide a link next to the map that will move the map to the 2nd marker when clicked. Here's a demo of what I want, using v2 of the API: http://arts.brighton.ac.uk/contact-university-of-brighton-faculty-of-arts (note the links below the map) Here's what I have so far: <script type="text/javascript"> function initialize() { var latlng = new google.maps.LatLng(50.823817, -0.135634); var myOptions = { zoom: 13, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP, mapTypeControlOptions: { style: google.maps.MapTypeControlStyle.DROPDOWN_MENU } , scaleControl: false }; var map = new google.maps.Map(document.getElementById("map"), myOptions); // 1st marker var marker1 = new google.maps.Marker({ position: new google.maps.LatLng(50.823817, -0.135634), map: map, title: 'my title' }); var infowindow = new google.maps.InfoWindow({ content: 'my window content' }); google.maps.event.addListener(marker1, 'click', function() { infowindow.open(map, marker1); }); // 2nd marker var marker2 = new google.maps.Marker({ position: new google.maps.LatLng(51.5262405, -0.074549), map: map, title: 'my 2nd title'}); var infowindow2 = new google.maps.InfoWindow({ content: 'content for my 2nd window' }); google.maps.event.addListener(marker2, 'click', function() { infowindow2.open(map, marker2); }); } </script> So what I'd like to add is a link to marker2, to move the map some 50-odd miles up, e.g. <a href="#marker2">Second location</a>. How would I do this?

  • Obtaining YouTube video ID in a URL and inputting selected video ID into a URL

    - by Dave
    I've been having trouble in trying to figure this out. What I am trying to do is, obtain the ID of a video from YouTube, and input the 11 character ID into the css of a div of a specific id by using jquery. I know the URL for the thumbnail of any video, but I just need to be able to change the ID to display different video thumbnails. <script> $(document).ready(function() { function(data){ videoID = data.split('www.youtube.com/v/')[1].split('&amp')[0]; $("#304817679").append(videoID); }); $("#304817679").replaceWith("<div id=\"304817679\" style=\"background: url(http://img.youtube.com/vi/"+ $.function(data) +"/0.jpg) no-repeat middle; width: 15px; height: 150px;\"></div>"); }); }); </script> <div id="304817679"> <div style="display: none;"><object width="248" height="222"><param name="movie" value="http://www.youtube.com/v/vy90n2nNRKQ&amp;rel=0&amp;egm=0&amp;showinfo=0&amp;fs=1"></param><param name="wmode" value="transparent"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/vy90n2nNRKQ&amp;rel=0&amp;egm=0&amp;showinfo=0&amp;fs=1" type="application/x-shockwave-flash" width="248" height="222" allowFullScreen="true" wmode="transparent"></embed></object></div> </div> Trying to explain this better, I want the 11 Character YouTube Video ID from the embedded code, and put it into the URL of the thumbnail (http://img.youtube.com/vi/"+ function(data) +"/0.jpg). Which, would then also replace the original div (div id="304817679"). Am I on the right track with my script? I'm entirely new to this, and I would appreciate some of the help that's offered here.

  • Cross-Platform Language + GUI Toolkit for Prototyping Multimedia Applications

    - by msutherl
    I'm looking for a language + GUI toolkit for rapidly prototyping utility applications for multimedia installations. I've been working with Max/MSP/Jitter for many years, but I'd like to add a text-based language to my 'arsenal' for tasks apart from 'content production'. (When it comes to actual media synthesis, my choices are clear [SuperCollider + MSP for audio, Jitter + Quartz + openFrameworks for video]). I'm looking for something that maintains some of the advantages of Max, but is lower-level, faster, more cross-platfrom (Linux support), and text-based. Integration with powerful sound/video libraries is not a requirement. Some requirements: Cross-platform (at least OSX and Linux, Windows is a plus) Fast and easy cross-platform GUIs with no platform-specific modification GUI code separated from backend code as much as possible Good for interfacing with external serial devices (micro-controllers) Good network support (UDP/TCP) Good libraries for multi-media (video, sound, OSC) are a plus Asynchronous synchronous UNIX integration is a plus The options that come to mind: AS3/Flex (not a fan of AS3 or the idea of running in the Flash Player) openFrameworks (C++ framework, perhaps a bit too low level [looking for fast development time] and biased toward video work) Java w/ Processing libraries (like openFrameworks, just slower) Python + Qt (is Qt appropriate for rapid prototyping?) Python + Another GUI toolkit SuperCollider + Swing (yucky GUI development) Java w/ SWT Any other options? What do you recommend?

  • 1k of Program Space, 64 bytes of RAM. Is assembly an absolute must?

    - by Earlz
    (If your lazy see bottom for TL;DR) Hello, I am planning to build a new (prototype) project dealing with physical computing. Basically, I have wires. These wires all need to have their voltage read at the same time. More than a few hundred microseconds difference between the readings of each wire will completely screw it up. The Arduino takes about 114 microseconds. So the most I could read is 2 or 3 wires before the latency would skew the accuracy of the readings. So my plan is to have an Arduino as the "master" of an array of ATTinys. The arduino is pretty cramped for space, but it's a massive playground compared to the tinys. An ATTiny13A has 1k of flash ROM(program space), 64 bytes of RAM, and 64 bytes of (not-durable and slow) EEPROM. (I'm choosing this for price as well as size) The ATTinys in my system will not do much. Basically, all they will do is wait for a signal from the Master, and then read the voltage of 1 or 2 wires and store it in RAM(or possibly EEPROM if it's that cramped). And then send it to the Master using only 1 wire for data.(no room for more than that!). So far then, all I should have to do is implement trivial voltage reading code (using built in ADC). But this communication bit I'm worried about. Do you think a communication protocol(using just 1 wire!) could even be implemented in such constraints? TL;DR: In less than 1k of program space and 64 bytes of RAM(and 64 bytes of EEPROM) do you think it is possible to implement a 1 wire communication protocol? Would I need to drop to assembly to make it fit? I know that currently my Arduino programs linking to the Wiring library are over 8k, so I'm a bit concerned.

  • Javascript: Whitespace Characters being Removed in Chrome (but not Firefox)

    - by Matrym
    Why would the below eliminate the whitespace around matched keyword text when replacing it with an anchor link? Note, this error only occurs in Chrome, and not firefox. For complete context, the file is located at: http://seox.org/lbp/lb-core.js To view the code in action (no errors found yet), the demo page is at http://seox.org/test.html. Copy/Pasting the first paragraph into a rich text editor (ie: dreamweaver, or gmail with rich text editor turned on) will reveal the problem, with words bunched together. Pasting it into a plain text editor will not. // Find page text (not in links) -> doxdesk.com function findPlainTextExceptInLinks(element, substring, callback) { for (var childi= element.childNodes.length; childi-->0;) { var child= element.childNodes[childi]; if (child.nodeType===1) { if (child.tagName.toLowerCase()!=='a') findPlainTextExceptInLinks(child, substring, callback); } else if (child.nodeType===3) { var index= child.data.length; while (true) { index= child.data.lastIndexOf(substring, index); if (index===-1 || limit.indexOf(substring.toLowerCase()) !== -1) break; // don't match an alphanumeric char var dontMatch =/\w/; if(child.nodeValue.charAt(index - 1).match(dontMatch) || child.nodeValue.charAt(index+keyword.length).match(dontMatch)) break; // alert(child.nodeValue.charAt(index+keyword.length + 1)); callback.call(window, child, index) } } } } // Linkup function, call with various type cases (below) function linkup(node, index) { node.splitText(index+keyword.length); var a= document.createElement('a'); a.href= linkUrl; a.appendChild(node.splitText(index)); node.parentNode.insertBefore(a, node.nextSibling); limit.push(keyword.toLowerCase()); // Add the keyword to memory urlMemory.push(linkUrl); // Add the url to memory } // lower case (already applied) findPlainTextExceptInLinks(lbp.vrs.holder, keyword, linkup); Thanks in advance for your help.

I want to host near to my WCF services my own TCP programm for direct sockets operations (like lien to some sort of broadcasting TCP stream) I need control over namespaces (so I would be able to let my clients to send TCP streams directly into my service using some nice URLs like example.com:port/myserver/stream?id=1 or example.com:port/myserver/stream?id=anything and so that I will not be bothered with Idea of 1 client for 1 socket at one time moment, I realy want to keep my WCF services on the same port as my own server or what it is so to be able to call www.example.com:port/myWCF/stream?id=222...) Can any body please help me with this? I am using just WCF now. And I do not enjoy how it works. That is one of many resons why I want to start migration to clear TCP=) I can not use net-tcp binding or any sort of other cool WS-* binding (tooday I use the simpliest one so that my clients like Flash, AJAX, etc connect to me with ease). I needed Fast and easy in implemrnting connection protocol like one I created fore use with Sockets for real time hi ammount of data transfering. So.. Any Ideas? Please - I need help.

  • PHP Uploadprogress extension function always returning null, with no upload data.

    - by abhinavlal
    I am using php 5.3.2 with uploadprogress extension to get a progressbar during upload using zend framework. Even the demo provided with zend is not working. code in zend example - if (isset($_GET['uploadId'])) { set_include_path(realpath(dirname(__FILE__) . '/../../../library') . PATH_SEPARATOR . get_include_path()); require_once 'Zend/ProgressBar.php'; require_once 'Zend/ProgressBar/Adapter/JsPull.php'; require_once 'Zend/Session/Namespace.php'; $data = uploadprogress_get_info($_GET['uploadId']); $bytesTotal = ($data === null ? 0 : $data['bytes_total']); $bytesUploaded = ($data === null ? 0 : $data['bytes_uploaded']); $adapter = new Zend_ProgressBar_Adapter_JsPull(); $progressBar = new Zend_ProgressBar($adapter, 0, $bytesTotal, 'uploadProgress'); if ($bytesTotal === $bytesUploaded) { $progressBar->finish(); } else { $progressBar->update($bytesUploaded); } } uploadprogress_get_info always returns null. I thought something is wrong with my code so i downloaded the working sample available at http://labs.liip.ch/uploadprogresssimple/index.php but even in that case in uploadprogress_get_info always return null. My uploadprogress config values uploadprogress support enabled Version 1.0.1 uploadprogress.file.contents_template /tmp/upload_contents_%s uploadprogress.file.filename_template /tmp/upt_%s.txt uploadprogress.get_contents 1 While googling around i found uploadprogress extension has some issue with Suhosin Patch < 0.9.26 but i am using Suhosin Patch 0.9.9.1

  • Best way to randomly select rows *per* column in SQL Server

    - by LesterDove
    A search of SO yields many results describing how to select random rows of data from a database table. My requirement is a bit different, though, in that I'd like to select individual columns from across random rows in the most efficient/random/interesting way possible. To better illustrate: I have a large Customers table, and from that I'd like to generate a bunch of fictitious demo Customer records that aren't real people. I'm thinking of just querying randomly from the Customers table, and then randomly pairing FirstNames with LastNames, Address, City, State, etc. So if this is my real Customer data (simplified): FirstName LastName State ========================== Sally Simpson SD Will Warren WI Mike Malone MN Kelly Kline KS Then I'd generate several records that look like this: FirstName LastName State ========================== Sally Warren MN Kelly Malone SD Etc. My initial approach works, but it lacks the elegance that I'm hoping the final answer will provide. (I'm particularly unhappy with the repetitiveness of the subqueries, and the fact that this solution requires a known/fixed number of fields and therefore isn't reusable.) SELECT FirstName = (SELECT TOP 1 FirstName FROM Customer ORDER BY newid()), LastName= (SELECT TOP 1 LastNameFROM Customer ORDER BY newid()), State = (SELECT TOP 1 State FROM Customer ORDER BY newid()) Thanks!

  • How does jquery display an image received from an ajax request?

    - by Gnee
    I have this working great, but I'd like a deeper understanding of what is actually going on behind the scenes. I am using Jquery's Ajax method to pull 5 blog posts (returning only the title and first photo). A PHP script grabs the blog posts' title and first photo and sticks it in an array and sends it back to my browser as JSON. Upon receiving the JSON object, Jquery grabs the first member of the JSON object and displays it's title and photo. In a gallery I made, using buttons – the user can iterate the 1-5 posts. So the actual AJAX call happens right away, and only once. I am basically using this kind of setup: $('my_div').html(json_obj[i]) and each click does a i++. So jquery is plucking these blog posts from my computers memory, my web browsers cache, or some kind of cache in the Javascript engine? One of the things it's returning is a pretty gnarly animated gif. I just wonder if it constantly running in the background (but not visible), stealing processing cycles...etc. Or Javascript just inserting (say a flash movie) into the DOM, but before hand does nothing but take up a little memory (no processing). Anyway, I'm just curious. If someone is a guru on this, I'd love to hear your take. Thanks!!

  • Launch .jar files with command line arguments (but with no console window)

    - by Virat Kadaru
    I have to do a demo of an application, the application has a server.jar and client.jar. Both have command line arguments and are executable. I need to launch two instances of server.jar and two instances of client.jar. I thought that using a batch file was the way to go, but, the batch file executes the first command (i.e. server.bat [argument1] [argument2]) and does not do anything else unless I close the first instance, in which case it then runs the 2nd command. And also the I do not want a blank console window to open (or be minimized) What I really need is a batch script that will just launch these apps without any console windows and launch all instances that I need. Thanks in Advance! EDIT: javaw: works if I type the command into the console window individually. If I put the same in the batch file, it will behave as before. Console window opens, one instance starts (whichever was first) and it does not proceed further unless I close the application in which case it runs the 2nd command. I want it to run all commands silently SOLUTION: Found the solution, below is the contents of my batch file @echo off start /B server.jar [arg1] [arg2] start /B server.jar [arg3] [arg4] @echo on this opens, runs all the commands and closes the window, does not wait for the command to finish.

  • error detection/correction/recovery in serial protocols

    - by Jason S
    I have some designing to do for a serial protocol and am running into some questions that I figure must have been considered elsewhere. So I'm wondering if there are some recommendations for best practices in designing serial protocols. (Please either state a fact that is easily verifiable, or cite a reputable source if you make a claim.) General recommendations for websites/books are also welcome. In particular I have to deal with issues like parsing a stream of bytes into packets verifying a packet is correct (easy with a CRC, for instance) identifying reasonable types of errors that can occur (e.g. in a point-to-point serial stream, sporadic single bit errors, and dropped series of bytes, are both likely, but extra phantom bytes are unlikely; whereas with a record stored in flash memory or on a disk drive the types of errors that predominate are different) error correction or recovery (if I detect an error in a packet, can I correct it? If not, can I resync to the boundary of the next packet?) how to make variable-length packets robust to error correction / recovery. Any suggestions?

My code looks good and obviously works since FF displays the playlist perfectly. I've got no idea how to solve this. Anyone? <script type='text/javascript'> var so = new SWFObject('/UI/Flash/player.swf', 'ply', '<%=FlashWidth %>', '<%=FlashHeight %>', '9', '#ffffff'), playlistURL = '<%=PlaylistURL %>', imageURL = '<%=GetBackgroundImageUrl() %>'; so.addParam('allowfullscreen', 'true'); so.addParam('allowscriptaccess', 'always'); if (playlistURL !== '') { so.addVariable('playlistfile', playlistURL); so.addVariable('playlist', 'none'); so.addVariable('enablejs', 'true'); } else { so.addVariable('file', '<%=FlashURL %>'); } if (imageURL.length > 0) { so.addVariable('image', imageURL); } so.write('preview<%=PlayerID %>'); </script>

  • How do set up jquery to exclude classes in a function?

    - by user1497158
    I essentially only understand how to read bits of javascript and make modifications. I am using grid-slider, a script I purchased, but the code writer is mia at the moment, so hopefully someone here can help me. Basically, it's a slider and there are options to have links open like normal or to have links open in a panel on the same page. I want some links to open in a panel and others to open in the parent window. It seems to me that all that would be required to do this would be to activate the panel display function (which I've done) and then set up an exclude function to exclude certain uls or lis with a specific class from the function. I've read about the .not selector, but I don't see how to make it applicable to this code: enter code hereelse { enter code here if (this._displayOverlay) { if ($item.find(">.content").size() > 0) { $item.data("type", "static"); } else { var contentType = this.getContentType($link); var url = $link.attr("href"); $item.data({type:contentType, url:(typeof url != "undefined") ? url : ""}); } $item.css("cursor", "pointer").bind("click", {elem:this, i:i}, this.openOverlay); } $link.data("text", $item.find(">div:first").html()); $img = $link.find(">img"); } Can anyone help based on looking at this? Here's a link to the demo of the code: http://codecanyon.net/item/jquery-grid-style-slider/full_screen_preview/1204040 Thank you.

  • What guidelines should be followed when using an unstable/testing/stable branching scheme?

    - by Elliot
    My team is currently using feature branches while doing development. For each user story in our sprint, we create a branch and work it in isolation. Hence, according to Martin Fowler, we practice Continuous Building, not Continuous Integration. I am interested in promoting an unstable/testing/stable scheme, similar to that of Debian, so that code is promoted from unstable = testing = stable. Our definition of done, I'd recommend, is when unit tests pass (TDD always), minimal documentation is complete, automated functional tests pass, and feature has been demo'd and accepted by PO. Once accepted by the PO, the story will be merged into the testing branch. Our test developers spend most of their time in this branch banging on the software and continuously running our automated tests. This scares me, however, because commits from another incomplete story may now make it into the testing branch. Perhaps I'm missing something because this seems like an undesired consequence. So, if moving to a code promotion strategy to solve our problems with feature branches, what strategy/guidelines do you recommend? Thanks.

  • Remove a tag type from the view

    - by user284194
    I have an index view that lists all of the tags for my Entry and Message models. I would like to only show the tags for Entries in this view. I'm using acts-as-taggable-on. Tags Controller: def index @letter = params[:letter].blank? ? 'a' : params[:letter] @tagged_entries = Tagging.find_all_by_taggable_type('Entry').map(&:taggable) #@tagged_messages = Tagging.find_all_by_taggable_type('Message') #@tagged_messages = Tagging.find_all_by_taggable_type('Message').map(&:taggable) @title = "Tags" if params[:letter] == '#' @data = Tag.find(@tagged_entries, :conditions => ["name REGEXP ?", "^[^a-z]"], :order => 'name', :select => "id, name") else @data = Tag.find(@tagged_entries, :conditions => ["name LIKE ?", "#{params[:letter]}%"], :order => 'name', :select => "id, name") end respond_to do |format| flash[:notice] = 'We are currently in Beta. You may experience errors.' format.html end end tags#index: <% @data.each do |t| %> <div class="tag"><%= link_to t.name.titleize, tag_path(t) %></div> <% end %> I want to show only the taggable type 'Entry' in the view. Any ideas? Thank you for reading my question.

  • I need a true mouseOver...

    - by invertedSpear
    Ok, so mouseOver and RollOver, and their respective outs work great as long as your mouse is actually over the item, or one of it's children. My problem is that I may have another UI component "between" my mouse and the item I want to process the mouse/rollover(maybe a button that is on top of a canvas, but is not a child of the canvas). The mouse is still over the component, there's just something else that it's over at the same time. Any tips or help how to deal with this? Let me know if I'm not being clear enough. Here is a simplified code example detailing my question copy/paste that into your flex/flash builder and you'll see what I mean: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="500" height="226" creationComplete="ccInit()"> <mx:Script> <![CDATA[ private function ccInit():void{ myCanv.addEventListener(MouseEvent.ROLL_OVER,handleRollOver); } private function handleRollOver(evt:MouseEvent):void{ myCanv.setStyle("backgroundAlpha",1); myCanv.addEventListener(MouseEvent.ROLL_OUT,handleRollOut); } private function handleRollOut(evt:MouseEvent):void{ myCanv.setStyle("backgroundAlpha",0); myCanv.removeEventListener(MouseEvent.ROLL_OUT,handleRollOut); } ]]> </mx:Script> <mx:Canvas id="myCanv" x="10" y="10" width="480" height="200" borderStyle="solid" borderColor="#000000" backgroundColor="#FFFFFF" backgroundAlpha="0"> </mx:Canvas> <mx:Button x="90" y="50" label="Button" width="327" height="100"/> </mx:Application>
