• Modifying UINavigation Bar Buttons in SubViews

  - by james

  I'm having trouble trying to modify the navigation bar in the subview portion of my application. self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(add_Clicked:)] autorelease]; I have no issues modifying the navigation bar in any of my UIViewControllers classes. The simplified application class outline is as such: AppDelegate - UIViewControllerA (has a left and a right navigationBarButton) - Subview is displayed when a SegmentControl is selected. (Within the subview, I'm trying to modify the right NavigationBarButton that is displayed) [self.view addSubview:newControllerName.view]; Methods I have attempted: Trying to set self.navigationItem.rightBarButtonItem within my subview to a new UIBarButtonItem. Creating a pointer to UIViewControllerA within my AppDelegate. The UIViewControllerA contains a function setNavButton I wrote to set the rightBarButtonItem to a button. Then I am referencing the AppDelegate's reference to UIViewControllerA and attempting to call setNavButton. I included a NSLog call to see if that function is being called and it is executing but the NavigationBar isn't being modified. I'm trying to avoid having to push a UIViewController after the SegmentControl is clicked in UIViewControllerA so that I can simulate the SegmentControl as tabs. I'm not getting any errors during compile or run time. Anyone have any ideas?

• How to run an external SWF inside a Flex Application?

  - by lk

  I want to run an Action Script 3.0 Application into a Flex Application. To do this I've done the following: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication windowComplete="loadSwfApplication()" xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script> <![CDATA[ private function loadSwfApplication() { var urlRequest:URLRequest = new URLRequest("path/to/the/application.swf"); swfLoader.addEventListener(Event.COMPLETE, loadComplete); swfLoader.load(urlRequest); } private function loadComplete(completeEvent:Event) { var swfApplication:* = completeEvent.target.content; swfApplication.init(); // this is a Function that I made it in the Root class of swfApplication } ]]> </mx:Script> <mx:SWFLoader id="sfwLoader"/> </mx:WindowedApplication> The problem is that in the calling of swfApplication.init(); the AIR Player throws me an exception: Security sandbox violation: caller file:///path/to/the/application.swf cannot access Stage owned by app:/SWFApplicationLoader.swf. This is because somewhere in application.swf I use the stage like this: if (root.stage != null) root.stage.addEventListener(Event.REMOVED, someFunction); root.stage.stageFocusRect = false; How can I load this swf application and USE the stage without any problems?

• Adding editFTPnetPRO to SSIS package causes error message

  - by gfrizzle

  I'm trying to add some secure FTP code to an SSIS package. I've used the EnterpriseDT product successfully on other .NET projects, so I wanted to incorporate it into an SSIS 2008 package I'm working on. If I create a Script Task (VB), edit the script, choose Project | Add Reference, and select the editFTPnetPRO.dll file, it comes back with this error: No template information found. See the application log in Event Viewer for more details. To open Event Viewer, click Start, click Control Panel, double-click Administrative Tools, and then double-click Event Viewer. The application log doesn't contain any pertinent details. I have no idea what this is trying to tell me. I've gone down a couple dead ends searching for this error message and following the prescribed fixes, but nothing has fixed it yet. Any idea what might be going wrong? P.S. - I tried the devenv.exe /installvstemplates fix, which didn't change anything. Update: Here is the error captured in the SSIS package when you try to run it: Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. --- System.IO.FileNotFoundException: Could not load file or assembly 'edtFTPnetPRO, Version=6.3.1.20, Culture=neutral, PublicKeyToken=0dce1ad63760d80b' or one of its dependencies. The system cannot find the file specified. Where is it looking for this file? I tried copying it to the project direcory, the bin folder, and the C:\WINDOWS\Microsoft.NET\Framework\v2.0.nnnn folder, but it still can't find it, and it won't tell me where it's looking.

• Problems with html forms.

  - by Michael

  My form views fine in IE7 and IE8 but FireFox does not display the form correctly: The problem is it does not display the form inside my "mainContent1" Note my code below: <div id="mainContent1"> <form action="forms.php" target="_self"> <fieldset> <legend>Postal Address</legend> <label for="street">Street address:</label> <input id="street" name="street" type="text" /> <label for=" suburb">County</label> <input id="county" name="county" type="text" /> <label for="state">State</label> <input id="state" name="state" type="text" /> <label for="zip">Zip Code</label> <input id="zip" name="zip" type="text" /> </fieldset> </form> </div>

• ArrayList in Java, adding code to methods

  - by yaz

  Why am I getting a compile time error for the two method headers at the end of my code in my class ArrayListTest? ArrayListTest: http://pastebin.com/dUHn9vPr Student: http://pastebin.com/3Vz1Aytr I have a compiler error at the two lines: delete(CS242, s3) replace(CS242, s, s4); When I try to run the code it states: Exception in thread "main" java.lang.Error: Unresolved compilation problems: The method replace(ArrayList<Student>, Student, Student)in the type ArrayListTest is not applicable for the arguments (List<Student>, Student, Student) The method delete(ArrayList<Student>, Student) in the type ArrayListTest is not applicable for the arguments (List<Student>, Student) at ArrayListTest.main(ArrayListTest.java:54) I fixed the compile time errors since I use Eclipse and Eclipse gives options of code you can use to fix the compile time error. I chose to "Change method to 'replace(ArrayList, Student, Student)' to 'replace(List, Student, Student)' Although it fixed that compile time error, I don't understand why I was getting a compile time error to begin with and why that effectively fixed the error I don't really know what missing code I need to write to correct these two methods below: public static void replace(List<Student> cS242, Student oldItem, Student newItem) { public static void delete(List<Student> cS242, Student target){

• How can I load a view based on how long I hold a UIButton?

  - by Thomas

  Hello all, I've searched the net and documentation, but haven't found anything quite like what I'm trying to do. I'm working on an app where I want to load one view if a UIButton is held for x seconds, another if it's held for x+y seconds, etc. I found this tutorial. The problem I'm running into is, how do I switch the length of the button press? The tutorial switched the number of taps. -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSSet *allTouches = [event allTouches]; switch ([allTouches count]) { case 1: // Single touch { // Get the first touch. UITouch *touch = [[allTouches allObjects] objectAtIndex:0]; switch ([touch tapCount]) { case 1: // Single Tap. { // Start a timer timer = [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(showAlertView:) userInfo:nil repeats:NO]; [timer retain]; } break; case 2: // Double tap. break; } } break; case 2: // Double touch { } break; default: break; } } Any suggestions? Thanks! Thomas

• Why use Django on Google App Engine?

  - by Travis Bradshaw

  When researching Google App Engine (GAE), it's clear that using Django is wildly popular for developing in Python on GAE. I've been scouring the web to find information on the costs and benefits of using Django, to find out why it's so popular. While I've been able to find a wide variety of sources on how to run Django on GAE and the various methods of doing so, I haven't found any comparative analysis on why Django is preferable to using the webapp framework provided by Google. To be clear, it's immediately apparent why using Django on GAE is useful for developers with an existing skillset in Django (a majority of Python web developers, no doubt) or existing code in Django (where using GAE is more of a porting exercise). My team, however, is evaluating GAE for use on an all-new project and our existing experience is with TurboGears, not Django. It's been quite difficult to determine why Django is beneficial to a development team when the BigTable libraries have replaced Django's ORM, sessions and authentication are necessarily changed, and Django's templating (if desirable) is available without using the entire Django stack. Finally, it's clear that using Django does have the advantage of providing an "exit strategy" if we later wanted to move away from GAE and need a platform to target for the exodus. I'd be extremely appreciative for help in pointing out why using Django is better than using webapp on GAE. I'm also completely inexperienced with Django, so elaboration on smaller features and/or conveniences that work on GAE are also valuable to me. Thanks in advance for your time!

• Design considerations for temporarily transforming a player into an animal in a role playing game

  - by mikedev

  I am working on a role playing game for fun and to practice design patterns. I would like players to be able to transform themselves into different animals. For example, a Druid might be able to shape shift into a cheetah. Right now I'm planning on using the decorator pattern to do this but my question is - how do I make it so that when a druid is in the cheetah form, they can only access skills for the cheetah? In other words, they should not be able to access their normal Druid skills. Using the decorator pattern it appears that even in the cheetah form my druid will be able to access their normal druid skills. class Druid : Character { // many cool druid skills and spells void LightHeal(Character target) { } } abstract class CharacterDecorator : Character { Character DecoratedCharacter; } class CheetahForm : CharacterDecorator { Character DecoratedCharacter; public CheetahForm(Character decoratedCharacter) { DecoratedCharacter= decoratedCharacter; } // many cool cheetah related skills void CheetahRun() { // let player move very fast } } now using the classes Druid myDruid = new Druid(); myDruid.LightHeal(myDruid); // casting light heal here is fine myDruid = new CheetahForm(myDruid); myDruid.LightHeal(myDruid); // casting here should not be allowed Hmmmm...now that I think about it, will myDruid be unable to us the Druid class spells/skills unless the class is down-casted? But even if that's the case, is there a better way to ensure that myDruid at this point is locked out from all Druid related spells/skills until it is cast back to a Druid (since currently it's in CheetahForm)

• GCC - How to realign stack?

  - by psihodelia

  I try to build an application which uses pthreads and __m128 SSE type. According to GCC manual, default stack alignment is 16 bytes. In order to use __m128, the requirement is the 16-byte alignment. My target CPU supports SSE. I use a GCC compiler which doesn't support runtime stack realignment (e.g. -mstackrealign). I cannot use any other GCC compiler version. My test application looks like: #include <xmmintrin.h> #include <pthread.h> void *f(void *x){ __m128 y; ... } int main(void){ pthread_t p; pthread_create(&p, NULL, f, NULL); } The application generates an exception and exits. After a simple debugging (printf "%p", &y), I found that the variable y is not 16-byte aligned. My question is: how can I realign the stack properly (16-byte) without using any GCC flags and attributes (they don't help)? Should I use GCC inline Assembler within this thread function f()?

• model view controller question

  - by songBong

  Hi, I've been working on my iphone game recently and came across a forked road when deciding the design of my various classes. So far I've adhered to the MVC pattern but the following situation had me confused: I have 4 buttons displayed visually. Each button though consists of a container UIView (which I've subclassed) and 2 UIButtons (also subclassed) as subviews. When you press a button, it does the flip effect plus other stuff. The user input is using target-action from my container UIView to my controller. This part is ok, the following part is the debatable part: So I've subclassed the container view as well as the UIButtons and I need to add more data/methods (somewhere) to do more things. Putting data that needs to be serialized and non-rendering related code in the view classes seems to break the MVC design but at the moment, it makes the most sense to me to put it there. It's almost like my subclassed views are their own little MVC's and it seems neat. Separating out the data/methods from the view to my main controller in this case seems unnecessary and a more work. How should I be doing it? Thanks heaps.

• Authenticating GTK app to run with root permissions

  - by Thomas Tempelmann

  I have a UI app (uses GTK) for Linux that requires to be run as root (it reads and writes /dev/disk*). Instead of requiring the user to open a root shell or use "sudo" manually every time when he launches my app, I wonder if the app can use some OS-provided API to ask the user to relaunch the app with root permissions. (Note: gtk app's can't use "setuid" mode, so that's not an option here.) The advantage here would be an easier workflow: The user could, from his default user account, double click my app from the desktop, and the app then would relaunch itself with root permission after been authenticated by the API/OS. I ask this because OS X offers exactly this: An app can ask the OS to launch an executable with root permissions - the OS (and not the app) then asks the user to input his credentials, verifies them and then launches the target as desired. I wonder if there's something similar for Linux (Ubuntu, e.g.) Update: The app is a remote operated disk repair tool for the unsavvy Linux user, and those Linux noobs won't have much understanding of using sudo or even changing their user's group memberships, especially if their disk just started acting up and they're freaking out. That's why I seek a solution that avoids technicalities like this.

• Hiding Command Prompt with CodeDomProvider

  Hi All I've just got my own little custom c# compiler made, using the article from MSDN. But, when I create a new Windows Forms application using my sample compiler, the MSDOS window also appears, and if I close the DOS window, my WinForms app closes too. How can I tell the Compiler? not to show the MSDOS window at all? Thank you :) Here's my code: using System; namespace JTS { public class CSCompiler { protected string ot, rt, ss, es; protected bool rg, cg; public string Compile(String se, String fe, String[] rdas, String[] fs, Boolean rn) { System.CodeDom.Compiler.CodeDomProvider CODEPROV = System.CodeDom.Compiler.CodeDomProvider.CreateProvider("CSharp"); ot = fe; System.CodeDom.Compiler.CompilerParameters PARAMS = new System.CodeDom.Compiler.CompilerParameters(); // Ensure the compiler generates an EXE file, not a DLL.

• Automatic multi-page multi-column flowing text with QtWebkit (HTML/CSS/JS -> PDF)

  - by Peter Boughton

  I have some HTML documents that are converted to PDF, using software that renders using QtWebkit (not sure which version). Currently, the documents have specific tags to split into columns and pages - so whenever the wording changes, it is a manual time-consuming process to move these tags so that the columns and pages fit. Can anyone provide a way to have text auto-wrapped into the next column/page (as appropriate) when it reaches the bottom of the current container? Any HTML, CSS or JS supported by QtWebkit is ok (assuming it works in the PDF converter). (I have tested the webkit-column-* in CSS3 and it appears QtWebkit does not support this.) To make things more exciting, it also needs to: - put a header at the top of each page, with page X of Y numbering; - if an odd number of pages, add a blank page at the end (with no header); - have the ability to say "don't break inside this block" or "don't break after this header" I have put some quick example initial markup and target markup to help explain what I'm trying to do. (The actual documents are far more complicated than that, but I need a simple proof-of-concept before I attack the real ones.) Any suggestions? Update: I've got a partially working solution using Aaron's "filling up" suggestion - I'll post more details in a bit.

• Display object in just a certain viewport

  - by PSilo

  Hi I got 4 viewports and one large that I can switch between now I got an object namely the camera and the cameras target position that I show with rendering a sphere at those locations. I want to show the cameras position in 3 of my viewports but not in the last which is the camera display but at the moment I got an all or nothing scenario. void display(int what) { if(what==5){ glMatrixMode(GL_MODELVIEW); glLoadIdentity(); camControll();} if(what==1){ glMatrixMode(GL_MODELVIEW); glLoadIdentity(); gluLookAt(75,15,-5,0,5,-5,0,1,0);} if(what==2){ glMatrixMode(GL_MODELVIEW); glLoadIdentity(); gluLookAt(0,110,0,0,0,0,1,0,0);} if(what==3){ glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective(45.0f, float(320) / float(240), 0.1f, 100.0f); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); camControll();} if(what==4){ glMatrixMode(GL_MODELVIEW); glLoadIdentity(); gluLookAt(185,75,25,0,28,0,0,1,0);} //glMatrixMode(GL_MODELVIEW); //glLoadIdentity(); ////gluLookAt(cos(shared.time) * shared.distance, 10, sin(shared.time) * shared.distance, 0, 0, 0, 0, 1, 0); ////ca.orbitYaw(0.05); //ca.lookAt(); glClearColor(0, 0, 0, 1); glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT); drawScene(); // scene that all views should render drawCamera(); / camera position that only certain views should render glutSwapBuffers(); } I'm thinking that perhaps I could do one sweep for first the 3 viewports and then call glutSwapBuffers() and then do the other viewport without the camera position but some stuttering I previously had was traced to glutSwapBuffers() being called for each viewport so I guess there has to be another way only that I cant figure it out.

• The uncatchable exception

  - by chaiguy

  Another custom MarkupExtension binding question... This time, my converter is being called before DataContext is set on the target element. This isn't a big deal because it will get updated when DataContext eventually receives a value. What is causing problems is the NullReferenceException I'm getting because of DataContext being null. Even though I'm attempting to catch the exception in my value converter: try { return ( (MethodInfo)_member ).Invoke( parameter, null ); } catch { return Binding.DoNothing; } For some reason the debugger is still halting at this point. Now I'm thinking it could be because the exception is happening in another assembly from where it is being caught (I'm trying to package this in a reusable class library, and _member above points to a method in the application assembly). If I run my little test app without the debugger it works fine, however my application is a little more robust and has general exception handling which is getting triggered because of this. I'm wondering if there is just some attribute or something (or perhaps some reflection parameter I'm missing?) I can use to make the exception be caught like it's supposed to.

• QueryReadStore loads JSON into DataGrid, but JsonRestStore does not (from the same source)

  - by labratmatt

  I'm building a Dojo DataGrid from JSON data provided by my REST interface. The DataGrid loads the data fine using a QueryReadStore, but doesn't seem to work with the same same data piped into a JsonRestStore. I'm using the following Dojo libs with Dojo 1.4.1: dojo.require("dojox.data.JsonRestStore"); dojo.require("dojox.grid.DataGrid"); dojo.require("dojox.data.QueryReadStore"); dojo.require("dojo.parser"); I declare my stores in the following manner: var storeJRS = new dojox.data.JsonRestStore({target:"api/collaborations.php/1", idAttribute: 'items[].id'}); var storeQRS = new dojox.data.QueryReadStore({url:"api/collaborations.php/1", requestMethod:"get"}); I create my grid layout like this: var gridLayout = [ new dojox.grid.cells.RowIndex({ name: "Row #", width: 5, styles: "text-align: left;" }), { name: "Name", field: "name", styles: "text-align:right;", width:20 }, { name: "Description", field: "description", width:30 } ]; I create my DataGrid as follows: The above works, but if I use QueryReadStore as my store, the grid is created with the headers (Name, Description), but it isn't populated with any rows: <div dojoType="dojox.grid.DataGrid" jsid="grid3" store="storeQRS" structure="gridLayout" style="height:500px; width:1000px;"></div> Using FireBug, I can see that QueryReadStore is getting my JSON data from my REST interface. It looks like the following: {"numRows":6,"items":[{"name":"My Super Cool Collab","description":"This is for all the super cool people in the super cool group","id":1},{"name":"My Other Super Cool","description":"This is for all the other super cool people","id":3},{"name":"This is another coll","description":"This is just some other collab","id":4},{"name":"some new collab","description":"this is a new collab","id":5},{"name":"yet another new coll","description":"uh huh","id":6},{"name":"asdf","description":"asdf","id":7}]} Any ideas?

• Resolving Circular References for Objects Implementing ISerializable

  - by Chris

  I'm writing my own IFormatter implementation and I cannot think of a way to resolve circular references between two types that both implement ISerializable. Here's the usual pattern: [Serializable] class Foo : ISerializable { private Bar m_bar; public Foo(Bar bar) { m_bar = bar; m_bar.Foo = this; } public Bar Bar { get { return m_bar; } } protected Foo(SerializationInfo info, StreamingContext context) { m_bar = (Bar)info.GetValue("1", typeof(Bar)); } public void GetObjectData(SerializationInfo info, StreamingContext context) { info.AddValue("1", m_bar); } } [Serializable] class Bar : ISerializable { private Foo m_foo; public Foo Foo { get { return m_foo; } set { m_foo = value; } } public Bar() { } protected Bar(SerializationInfo info, StreamingContext context) { m_foo = (Foo)info.GetValue("1", typeof(Foo)); } public void GetObjectData(SerializationInfo info, StreamingContext context) { info.AddValue("1", m_foo); } } I then do this: Bar b = new Bar(); Foo f = new Foo(b); bool equal = ReferenceEquals(b, b.Foo.Bar); // true // Serialise and deserialise b equal = ReferenceEquals(b, b.Foo.Bar); If I use an out-of-the-box BinaryFormatter to serialise and deserialise b, the above test for reference-equality returns true as one would expect. But I cannot conceive of a way to achieve this in my custom IFormatter. In a non-ISerializable situation I can simply revisit "pending" object fields using reflection once the target references have been resolved. But for objects implementing ISerializable it is not possible to inject new data using SerializationInfo. Can anyone point me in the right direction?

• Setting up a pc bluetooth server for android

  - by Del

  Alright, I've been reading a lot of topics the past two or three days and nothing seems to have asked this. I am writing a PC side server for my andriod device, this is for exchanging some information and general debugging. Eventually I will be connecting to a SPP device to control a microcontroller. I have managed, using the following (Android to pc) to connect to rfcomm channel 11 and exchange data between my android device and my pc. Method m = device.getClass().getMethod("createRfcommSocket", new Class[] { int.class }); tmp = (BluetoothSocket) m.invoke(device, Integer.valueOf(11)); I have attempted the createRfcommSocketToServiceRecord(UUID) method, with absolutely no luck. For the PC side, I have been using the C Bluez stack for linux. I have the following code which registers the service and opens a server socket: int main(int argc, char **argv) { struct sockaddr_rc loc_addr = { 0 }, rem_addr = { 0 }; char buf[1024] = { 0 }; char str[1024] = { 0 }; int s, client, bytes_read; sdp_session_t *session; socklen_t opt = sizeof(rem_addr); session = register_service(); s = socket(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM); loc_addr.rc_family = AF_BLUETOOTH; loc_addr.rc_bdaddr = *BDADDR_ANY; loc_addr.rc_channel = (uint8_t) 11; bind(s, (struct sockaddr *)&loc_addr, sizeof(loc_addr)); listen(s, 1); client = accept(s, (struct sockaddr *)&rem_addr, &opt); ba2str( &rem_addr.rc_bdaddr, buf ); fprintf(stderr, "accepted connection from %s\n", buf); memset(buf, 0, sizeof(buf)); bytes_read = read(client, buf, sizeof(buf)); if( bytes_read 0 ) { printf("received [%s]\n", buf); } sprintf(str,"to Android."); printf("sent [%s]\n",str); write(client, str, sizeof(str)); close(client); close(s); sdp_close( session ); return 0; } sdp_session_t *register_service() { uint32_t svc_uuid_int[] = { 0x00000000,0x00000000,0x00000000,0x00000000 };

sdp_set_access_protos( record, access_proto_list ); // set the name, provider, and description sdp_set_info_attr(record, service_name, service_prov, service_dsc); int err = 0; sdp_session_t *session = 0;

• How to instantiate spring bean without being referenced from aop:aspect

  - by XDeveloper

  Using Spring and Java; I have a pointcut which works OK. Now I want to remove the pointcut and AOP from the spring and just trigger the event with an event from inside the java code but I want "myAdvice" bean still called via Spring and its properties set. I want to get ridoff all advice things even in java code, no more advice or any trace of AOP, I already have a nice event system working. I just want to instantiate my bean via Spring. When I remove the second code block (one starting with "aop:config") then I noticed the bean "myAdvice" is not called and instantiated anymore. How can i stil call it set its properties without referencing it from the "aop:aspect" ? in my application context ; <bean id="myAdvice" class="com.myclass"> <property name="name1" ref="ref1" /> <property name="name2" ref="ref2" /> </bean> <aop:config proxy-target-class="true"> <aop:aspect id="myAspect" ref="myAdvice"> <aop:pointcut id="myPointcut" expression="execution(* com.myexcmethod" /> <aop:around pointcut-ref="myPointcut" method="invoke" /> </aop:aspect> </aop:config>

• Convert a Relative URL to an Absolute URL in Actionscript / Flex

  - by Bear

  I am working with Flex, and I need to take a relative URL source property and convert it to an absolute URL before loading it. The specific case I am working with involves tweaking SoundEffect's load method. I need to determine if a file will be loaded from the local file system or over the network from looking at the source property, and the easiest way I've found to do this is to generate the absolute URL. I'm having trouble generating the absolute URL for sound effect in particular. Here were my initial thoughts, which haven't worked. Look for the DisplayObject that the Sound Effect targets, and use its loaderInfo property. The target is null when the SoundEffect loads, so this doesn't work. Look at FlexGlobals.topLevelApplication, at the url or loaderInfo properties. Neither of these are set, however. Look at the FlexGlobals.topLevelApplication.systemManager.loaderInfo. This was also not set. The SoundEffect.as code basically boils down to var url:String = "mySound.mp3"; /*>> I'd like to convert the URL to absolute form here and tweak it as necessary <<*/ var req:URLRequest = new URLRequest(url); var loader:Loader = new Loader(); loader.load(req); Does anyone know how to do this? Any help clarifying the rules of how relative urls are resolved for URLRequests in ActionScript would also be much appreciated. edit I would also be perfectly satisfied with some way to tell whether the url will be loaded from the local file system or over the network. Looking at an absolute URL it would just be easy to look at the prefix, like file:// or http://.
