• How to make sliding button sidebar in Flex

  - by Tam

  Hi, I'm fairly new to Flex. I want to make a button (icon) on the far right in the middle of the page that display a sliding side bar with multiple buttons in it when you hover over it. I want when the user hover out of the button bar it slides back again. Conceptually I got the basics of that to work. The issue I'm having is that when the user moves the mouse between the buttons in the sidebar it kicks in changing state and side bar slides back again. I tried using different types of containers and I got the same results. Any Advice? Thanks, Tam Here is the code: <?xml version="1.0" encoding="utf-8"?> <s:VGroup xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/halo" xmlns:vld ="com.lal.validators.*" xmlns:effect="com.lal.effects.*" width="150" horizontalAlign="right" gap="0"> <fx:Script> <![CDATA[ import com.lal.model.LalModelLocator; var _model:LalModelLocator = LalModelLocator.getInstance(); ]]> </fx:Script> <fx:Declarations> <mx:ArrayCollection id="someData"> </mx:ArrayCollection> </fx:Declarations> <s:states> <s:State name="normal" /> <s:State name="expanded" /> </s:states> <fx:Style source="/styles.css"/> <s:transitions> <s:Transition fromState="normal" toState="expanded" > <s:Sequence> <s:Wipe direction="left" duration="250" target="{buttonsGroup}" /> </s:Sequence> </s:Transition> <s:Transition fromState="expanded" toState="normal" > <s:Sequence> <s:Wipe direction="right" duration="250" target="{buttonsGroup}" /> </s:Sequence> </s:Transition> </s:transitions> <s:Button skinClass="com.lal.skins.CalendarButtonSkin" id="calendarIconButton" includeIn="normal" verticalCenter="0" mouseOver="currentState = 'expanded'"/> <s:Panel includeIn="expanded" id="buttonsGroup" mouseOut="currentState = 'normal' " width="150" height="490" > <s:layout> <s:VerticalLayout gap="0" paddingRight="0" /> </s:layout> <s:Button id="mondayButton" width="120" height="70" mouseOver="currentState = 'expanded'"/> <s:Button id="tuesdayButton" width="120" height="70" mouseOver="currentState = 'expanded'"/> <s:Button id="wednesdayButton" width="120" height="70" mouseOver="currentState = 'expanded'"/> <s:Button id="thursdayButton" width="120" height="70" mouseOver="currentState = 'expanded'"/> <s:Button id="fridayButton" width="120" height="70" mouseOver="currentState = 'expanded'"/> <s:Button id="saturdayButton" width="120" height="70" mouseOver="currentState = 'expanded'"/> <s:Button id="sundayButton" width="120" height="70" mouseOver="currentState = 'expanded'"/> </s:Panel> </s:VGroup>

• Flex 4: Traversing the Stage More Easily

In order to do this I need to find the column chart on the stage using actionscript. I've currently got 3 lines of code in here to do this: var selectedTab:NavigatorContent = this.tn.selectedChild as NavigatorContent; var colChart:ColumnChart = selectedTab.getChildByName("CC") as ColumnChart; trace(selectedTab.getChildAt(0)); Getting to the active tab in the tabnavigator is easy enough, but then selectedTab.getChildAt(0) - which I was expecting to be the chart - is a "spark.skin.spark.SkinnableContainerSkin"...anyway, I can continue to traverse the tree using this somewhat annoying code, but I'm hoping there is an easier way. So in short, at run time I want to, with as little code as possible, identify the column chart in the active tab so I can redraw it. Any advice would be greatly appreciated.

• Retrieving Encrypted Rich Text file and showing it in a RichTextBox C#

  - by Ranhiru

  OK, my need here is to save whatever typed in the rich text box to a file, encrypted, and also retrieve the text from the file again and show it back on the rich textbox. Here is my save code. private void cmdSave_Click(object sender, EventArgs e) { FileStream fs = new FileStream(filePath, FileMode.Create, FileAccess.Write); AesCryptoServiceProvider aes = new AesCryptoServiceProvider(); aes.GenerateIV(); aes.GenerateKey(); aes.Mode = CipherMode.CBC; TextWriter twKey = new StreamWriter("key"); twKey.Write(ASCIIEncoding.ASCII.GetString(aes.Key)); twKey.Close(); TextWriter twIV = new StreamWriter("IV"); twIV.Write(ASCIIEncoding.ASCII.GetString(aes.IV)); twIV.Close(); ICryptoTransform aesEncrypt = aes.CreateEncryptor(); CryptoStream cryptoStream = new CryptoStream(fs, aesEncrypt, CryptoStreamMode.Write); richTextBox1.SaveFile(cryptoStream, RichTextBoxStreamType.RichText); } I know the security consequences of saving the key and iv in a file but this just for testing :) Well, the saving part works fine which means no exceptions... The file is created in filePath and the key and IV files are created fine too... OK now for retrieving part where I am stuck :S private void cmdOpen_Click(object sender, EventArgs e) { OpenFileDialog openFile = new OpenFileDialog(); openFile.ShowDialog(); FileStream openRTF = new FileStream(openFile.FileName, FileMode.Open, FileAccess.Read); AesCryptoServiceProvider aes = new AesCryptoServiceProvider(); TextReader trKey = new StreamReader("key"); byte[] AesKey = ASCIIEncoding.ASCII.GetBytes(trKey.ReadLine()); TextReader trIV = new StreamReader("IV"); byte[] AesIV = ASCIIEncoding.ASCII.GetBytes(trIV.ReadLine()); aes.Key = AesKey; aes.IV = AesIV; ICryptoTransform aesDecrypt = aes.CreateDecryptor(); CryptoStream cryptoStream = new CryptoStream(openRTF, aesDecrypt, CryptoStreamMode.Read); StreamReader fx = new StreamReader(cryptoStream); richTextBox1.Rtf = fx.ReadToEnd(); //richTextBox1.LoadFile(fx.BaseStream, RichTextBoxStreamType.RichText); } But the richTextBox1.Rtf = fx.ReadToEnd(); throws an cryptographic exception "Padding is invalid and cannot be removed." while richTextBox1.LoadFile(fx.BaseStream, RichTextBoxStreamType.RichText); throws an NotSupportedException "Stream does not support seeking." Any suggestions on what i can do to load the data from the encrypted file and show it in the rich text box?

• Flex: convert VideoPlayer.currentTime to string "00:00:00:000"

  - by numediaweb

  Hi there! what about this one: I want to format the currentTime displayed by a videoPlayer component inside flex, something like : 8230.999 to something like 01:59:59:999 which is "hours:minutes:seconds:milliseconds" I trie different sets of codes but they can't get it to work because currentTime is nor a correct miliseconds time as it adds a floating 3 digit point to seconds; so instead of : 2000ms it outputs 2.000 something people like me just can't understand! thanx for any help :) ### UPDATE I still have problem with milliseconds. here's the current MXML: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"> <fx:Script> <![CDATA[ protected function convert_clickHandler(event:MouseEvent):void { var val:Number = new Number(inPut.text); //inPut.text = 1000.001 //val = val * 1000; outPut.text = timeFormat(val); } public static function timeFormat(value:Number):String { var milliseconds:Number = value % 1000; var seconds:Number = Math.floor((value/1000) % 60); var minutes:Number = Math.floor((value/60000) % 60); var hours:Number = Math.floor((value/3600000) % 24); var s_miliseconds:String = (milliseconds<10 ?

• How do I use data from the main window in a sub-window?

  - by eagle

  I've just started working on a photo viewer type desktop AIR app with Flex. From the main window I can launch sub-windows, but in these sub-windows I can't seem to access the data I collected in the main window. How can I access this data?

• Check to see if CallResponder is processing

  - by Travesty3

  I'm using Flash Builder 4.6. As a simple example, say I have the following application: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:sdk="services.sdk.*"> <fx:Script> <![CDATA[ private function btnGetValue_clickHandler():void { getValueResult.token = sdk.getValue(); } private function getValueResultHandler():void { // ... } ]]> </fx:Script> <fx:Declarations> <sdk:SDK id="sdk" fault="{Alert.show(event.fault.faultString +'\n\n'+ event.fault.faultDetail, 'SDK ERROR');}" showBusyCursor="false"/> <s:CallResponder id="getValueResult" result="getValueResultHandler()"/> </fx:Declarations> <s:Button id="btnGetValue" click="btnGetValue_clickHandler()" label="Get Value" /> </s:Application> So when you click on the button, it calls a PHP file and when it gets a result, it calls getValueResultHandler(). Easy enough. But what if the response from the PHP file takes a second or two and the user clicks the button rapidly? Then the result handler function may not get called every time, since the call responder gets a new token before it received the last response. Is there a standard way of resolving this issue? I came up with the following workaround, and it works fine, but it seems like this issue would be common enough to have a more built-in solution. My workaround is: var getValueResultProcessing:Boolean = false; private function btnGetValue_clickHandler():void { var interval:uint = setInterval(function():void { if (!getValueResultProcessing) { getValueResultProcessing = true; getValueResult.token = sdk.getValue(); clearInterval(interval); } }, 100); getValueResult.token = sdk.getValue(); } private function getValueResultHandler():void { getValueResultProcessing = false; // ... } Any better way of resolving this issue?

• Replace Infinite loop in Flex

  - by H P

  Hello, I want to access a webservice:getMonitorData() , on creationcomplete and returns an array, in an infinite loop so that the getIndex0.text is updated each time. Flex is not able to handle an infinite loop and gives a timeout error 1502. If I run the for loop until i<2000 or so it works fine. How can replace the loop so that my webservice is accessed continiously and the result is shown in getIndex0.text.

• Thread too slow. Better way to execute code (Android AndEngine)?

  - by rphello101

  I'm developing a game where the user creates sprites with every touch. I then have a thread run to check to see if those sprites collide with any others. The problem is, if I tap too quickly, I cause a null pointer exception error. I believe it's because I'm tapping faster than my thread is running. This is the thread I have: public class grow implements Runnable{ public grow(Sprite sprite){ } @Override public void run() { float radf, rads; //fill radius/stationary radius float fx=0, fy=0, sx, sy; while(down){ if(spriteC[spriteNum].active){ spriteC[spriteNum].sprite.setScale(spriteC[spriteNum].scale += 0.001); if(spriteC[spriteNum].sprite.collidesWith(ground)||spriteC[spriteNum].sprite.collidesWith(roof)|| spriteC[spriteNum].sprite.collidesWith(left)||spriteC[spriteNum].sprite.collidesWith(right)){ down = false; spriteC[spriteNum].active=false; yourScene.unregisterTouchArea(spriteC[spriteNum].sprite); } fx = spriteC[spriteNum].sprite.getX(); fy = spriteC[spriteNum].sprite.getY(); radf=spriteC[spriteNum].sprite.getHeightScaled()/2; Log.e("F"+Float.toString(fx),Float.toString(fy)); if(spriteNum>0) for(int x=0;x<spriteNum;x++){ rads=spriteC[x].sprite.getHeightScaled()/2; sx = spriteC[x].body.getWorldCenter().x * 32; sy = spriteC[x].body.getWorldCenter().y * 32; Log.e("S"+Float.toString(sx),Float.toString(sy)); Log.e(Float.toString((float) Math.sqrt(Math.pow((fx-sx),2)+Math.pow((fy-sy),2))),Float.toString((radf+rads))); if(Math.sqrt(Math.pow((fx-sx),2)+Math.pow((fy-sy),2))<(radf+rads)){ down = false; spriteC[spriteNum].active=false; yourScene.unregisterTouchArea(spriteC[spriteNum].sprite); Log.e("Collided",Boolean.toString(down)); } } } } spriteC[spriteNum].body = PhysicsFactory.createCircleBody(mPhysicsWorld, spriteC[spriteNum].sprite, BodyType.DynamicBody, FIXTURE_DEF); mPhysicsWorld.registerPhysicsConnector(new PhysicsConnector(spriteC[spriteNum].sprite, spriteC[spriteNum].body, true, true)); } } Better solution anyone? I know there is something to do with a handler, but I don't exactly know what that is or how to use one.

• C++ property system interface for game editors (reflection system)

  - by Cristopher Ismael Sosa Abarca

  I have designed an reusable game engine for an project, and their functionality is like this: Is a completely scripted game engine instead of the usual scripting languages as Lua or Python, this uses Runtime-Compiled C++, and an modified version of Cistron (an component-based programming framework).to be compatible with Runtime-Compiled C++ and so on. Using the typical GameObject and Component classes of the Component-based design pattern, is serializable via JSON, BSON or Binary useful for selecting which objects will be loaded the next time. The main problem: We want to use our custom GameObjects and their components properties in our level editor, before used hardcoded functions to access GameObject base class virtual functions from the derived ones, if do you want to modify an property specifically from that class you need inside into the code, this situation happens too with the derived classes of Component class, in little projects there's no problem but for larger projects becomes tedious, lengthy and error-prone. I've researched a lot to find a solution without luck, i tried with the Ogitor's property system (since our engine is Ogre-based) but we find it inappropiate for the component-based design and it's limited only for the Ogre classes and can lead to performance overhead, and we tried some code we find in the Internet we tested it and worked a little but we considered the macro and lambda abuse too horrible take a look (some code omitted): IWE_IMPLEMENT_PROP_BEGIN(CBaseEntity) IWE_PROP_LEVEL_BEGIN("Editor"); IWE_PROP_INT_S("Id", "Internal id", m_nEntID, [](int n) {}, true); IWE_PROP_LEVEL_END(); IWE_PROP_LEVEL_BEGIN("Entity"); IWE_PROP_STRING_S("Mesh", "Mesh used for this entity", m_pModelName, [pInst](const std::string& sModelName) { pInst->m_stackMemUndoType.push(ENT_MEM_MESH); pInst->m_stackMemUndoStr.push(pInst->getModelName()); pInst->setModel(sModelName, false); pInst->saveState(); }, false); IWE_PROP_VECTOR3_S("Position", m_vecPosition, [pInst](float fX, float fY, float fZ) { pInst->m_stackMemUndoType.push(ENT_MEM_POSITION); pInst->m_stackMemUndoVec3.push(pInst->getPosition()); pInst->saveState(); pInst->m_vecPosition.Get()[0] = fX; pInst->m_vecPosition.Get()[1] = fY; pInst->m_vecPosition.Get()[2] = fZ; pInst->setPosition(pInst->m_vecPosition); }, false); IWE_PROP_QUATERNION_S("Orientation (Quat)", m_quatOrientation, [pInst](float fW, float fX, float fY, float fZ) { pInst->m_stackMemUndoType.push(ENT_MEM_ROTATE); pInst->m_stackMemUndoQuat.push(pInst->getOrientation()); pInst->saveState(); pInst->m_quatOrientation.Get()[0] = fW; pInst->m_quatOrientation.Get()[1] = fX; pInst->m_quatOrientation.Get()[2] = fY; pInst->m_quatOrientation.Get()[3] = fZ; pInst->setOrientation(pInst->m_quatOrientation); }, false); IWE_PROP_LEVEL_END(); IWE_IMPLEMENT_PROP_END() We are finding an simplified way to this, without leading confusing the programmers, (will be released to the public) i find ways to achieve this but they are only available for the common scripting as Lua or editors using C#. also too portable, we can write "wrappers" for different GUI toolkits as Qt or GTK, also i'm thinking to using Boost.Wave to get additional macro functionality without creating my own compiler. The properties designed to use in the editor they are removed in the game since the save file contains their data and loads it using an simple 'load' function to reduce unnecessary code bloat may will be useful if some GameObject property wants to be hidden instead. In summary, there's a way to implement an reflection(property) system for a level editor based in properties from derived classes? Also we can use C++11 and Boost (restricted only to Wave and PropertyTree)

• Rendering MXML component only after actionscript is finished

  - by basicblock

  In my mxml file, I'm doing some calculations in the script tag, and binding them to a custom component. <fx:Script> <![CDATA[ [Bindable] public var calc1:Number; [Bindable] public var calc2:Number; private function init():void { calc1 = //calculation; calc2 = //calculation; } ]]> </fx:Script> <mycomp:Ball compfield1="{calc1}" compfield2="{calc2}"/> The problem is that the mxml component is being created before the actionscript is run. So when the component is created, it actually doesn't get calc1 and calc2 and it fails from that point. I know that binding happens after that, but the component and its functions have already started and have run with the null or 0 initial values. My solution was to create the component also in actionscript right after calc1 and calc2 have been created. This way I get to control precisely when it's created <fx:Script> <![CDATA[ [Bindable] public var calc1:Number; [Bindable] public var calc2:Number; private function init():void { calc1 = //calculation; calc2 = //calculation; var Ball:Ball = new Ball(calc1, calc2); } ]]> </fx:Script> but this is creating all kinds of other problems due to the way I've set up the component. Is there a way I can still use mxml to create the component, yet control that it the <myComp:Ball> gets created only after init() is run and calc1 calc2 evaluated?

• wcf callback exception after updating to .net 4.0

  - by James

  I have a wcf service that uses callbacks with DualHttpBindings. The service pushes back a datatable of search results the client (for a long running search) as it finds them. This worked fine in .Net 3.5. Since I updated to .Net 4.0, it bombs out with a System.Runtime.FatalException that actually kills the IIS worker process. I have no idea how to even go about starting to fix this. Any recommendations appreciated. The info from the resulting event log is pasted below.

• Mootools Javascript can't push to array

  - by nona

  I have an array set with the heights of each hidden div, but when I use it, the div instantly jumps down, rather than slowly sliding as when there is a literal number. EDIT: testing seems to reveal that it's a problem with the push method, as content_height.push(item.getElement('.moreInfo').offsetHeight);alert(content_height[i]);gives undefined, but alert(item.getElement('.moreInfo').offsetHeight); gives the correct values Javascript: window.addEvent('domready', function(){ var content_height = [];i=0; $$( '.bio_accordion' ).each(function(item){ i++; content_height.push( item.getElement('.moreInfo').offsetHeight); var thisSlider = new Fx.Slide( item.getElement( '.moreInfo' ), { mode: 'horizontal' } ); thisSlider.hide(); item.getElement('.moreInfo').set('tween').tween('height', '0px'); var morph = new Fx.Morph(item.getElement( '.divToggle' )); var selected = 0; item.getElement( '.divToggle' ).addEvents({ 'mouseenter': function(){ if(!selected) this.morph('.div_highlight'); }, 'mouseleave': function(){ if(!selected) { this.morph('.divToggle'); } }, 'click': function(){ if (!selected){ if (this.getElement('.symbol').innerHTML == '+') this.getElement('.symbol').innerHTML = '-'; else this.getElement('.symbol').innerHTML = '+'; item.getElement('.moreInfo').set('tween', { duration: 1500, transition: Fx.Transitions.Bounce.easeOut }).tween('height', content_height[i]); //replacing this with '650' keeps it smooth selected = 1; thisSlider.slideIn(); } else{ if (this.getElement('.symbol').innerHTML == '+') this.getElement('.symbol').innerHTML = '-'; else this.getElement('.symbol').innerHTML = '+'; thisSlider.slideOut(); item.getElement('.moreInfo').set('tween', { duration: 1000, transition: Fx.Transitions.Bounce.easeOut }).tween('height', '0px'); selected = 0; } } }); } ); }); Why could this be?

• Flex 4: Scale to a point (zoom into an image where the mouse was clicked)

  - by Jason W

  I've been trying to get this working and I can't seem to figure it out. There is an Image control that when I click on it I need to zoom in (using the center/transform point where the mouse is clicked). I have the zoom transition working great, but when I set transformX & tranformY (with autoCenterTransform false) it doesn't zoom into that point. Here is my code that only zooms in (not to a specific point) <fx:Script> <![CDATA[ protected function imgLogo_clickHandler(event:MouseEvent):void { transformer.play(); } ]]> </fx:Script> <fx:Declarations> <s:Parallel id="transformer" target="{imgLogo}"> <s:Scale scaleXBy="0.5" scaleYBy="0.5" /> </s:Parallel> </fx:Declarations> <mx:Image id="imgLogo" width="250" x="100" y="100" maintainAspectRatio="true" source="@Embed('src/logo.png')" click="imgLogo_clickHandler(event)" /> Any help is greatly appreciated.
