  • ubuntu boots into gnu grub 1.99

    - by greenish
    I've tried set root=(hd0,2) chainloader +1 boot set root=(hd0,2) linux /boot/vmlinuz... and the loopback (loop0) /ubuntu/disks/root.disk command etc. When I try the boot command it tells me there's no kernel and when I boot Win7 (it's a dual boot) the root.disk says 0kb. nothing boots from the live usb I've made and I've tried to use programs to mount the partitions to no effect - they only show me what's on my windows file drives. I've got some really important docs on the linux harddrive I need to get to. any ideas?

  • How to use cursor keys to switch buffers in GNU screen

    - by suvayu
    I want to use cursor keys or cursor keys with a modifier like Ctrl to switch between screen buffers (e.g. C-a [arrow] or C-a C-[arrow]). So far I have tried settings like the ones below with no success. bind \224\115 prev bind \224\116 next bindkey -d ^[[1;5D prev bindkey -d ^[[1;5C next They are either ignored or behave unexpectedly (the second one). I am also not sure how to specify the keys. To get the characters, I either used C-v to quote them in bash, or tried to look-up on the Internet (e.g. http://ascii-table.com/ansi-escape-sequences.php). Any idea how I can achieve this key binding?

  • I am stuck at the "GNU" screen and I need to know how to get past it

    - by Comet
    I have had Ubuntu 12.04 for 6 days now and now, for some reason, I am getting the GRUB screen when I try to restart my computer. When I turn it on, it asks me, since I also have Windows 7 on my laptop, if I want to start with windows 7 or Ubuntu. When I choose Ubuntu, it brings me to the GRUB screen. How do I get to my normal Ubuntu desktop when in my computer appears the next message? GNU version 1.99-21ubuntu3.9

  • Flex Debugger wont launch - Only on particular project.

    - by John Isaacks
    When trying to launch Flex debaugger on my project, it does not launch and I get an error instead. Every other project in different workspaces launches just fine. This is the only one giving me an issue. Here is the error: Process terminated without establishing connection to debugger.

  • php mysql flex unicode

    - by JonoB
    I have a problem with saving the £ symbol to a mysql database. I am running a flex front end, with a php + mysql backend When I save a record from flex, the string gets sent to the server as "This amount is £10" php views the string as above, and when it gets saved into the DB, it gets saved as "This amount is £10". My understanding is that this is correct based on MySQL or PHP is appending a  whenever the £ is used I now retrieve the above record, and it gets sent to flex as "This amount is £10". Flex correctly displays this in a textarea as "This amount is £10" I change another field in the same record in flex, and re-save the transaction. The string now gets sent to the server as "This amount is £10" The record is now saved into the DB as "The amount is £10". Each time the record is re-saved, this effect snowballs. Thanks for any advice you can give.

  • Setting up multiple channel types (AMF/AMFX) for Flex/BlazeDs

    - by Fergal
    We've configured our Flex client to have two channels for calling our services via BlazeDS. One channel is configured to use AMFChannel and the other for HTTPChannel. Here's the services-config.xml <channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel"> <endpoint url="http://{server.name}:{server.port}/{context.root}/data/messagebroker/amf" class="flex.messaging.endpoints.AMFEndpoint" /> <properties> <polling-enabled>false</polling-enabled> </properties> </channel-definition> <channel-definition id="my-amfx" class="mx.messaging.channels.HTTPChannel"> <endpoint url="http://{server.name}:{server.port}/{context.root}/data/messagebroker/amfx" class="flex.messaging.endpoints.HTTPEndpoint" /> <properties> <polling-enabled>false</polling-enabled> </properties> </channel-definition> Our flex client is written to use either AMF or AMFX depending on how we configure it. The problem is that although the client can switch between channels it sends an AMF binary payload when attempting to call services via AMFX (expecting XML). The funny thing is that we can write services-config.xml to use either AMF or AMFX individually but Flex doesn't seem to want to let us use both. Is this a bug in Flex? If not how can we get it to use the correct protocol?

  • Silverlight vs Flex

    - by 1kevgriff
    My company develops several types of applications. A lot of our business comes from doing multimedia-type apps, typically done in Flash. However, now that side of the house is starting to migrate towards doing Flex development. Most of our other development is done using .NET. I'm trying to make a push towards doing Silverlight development instead, since it would take better advantage of the .NET developers on staff. I prefer the Silverlight platform over the Flex platform for the simple fact that Silverlight is all .NET code. We have more .NET developers on staff than Flash/Flex developers, and most of our Flash/Flex developers are graphic artists (not real programmers). Only reason they push towards Flex right now is because it seems like the logical step from Flash. I've done development using both, and I honestly believe Silverlight is easier to work with. But I'm trying to convince people who are only Flash developers. So here's my question: If I'm going to go into a meeting to praise Silverlight, why would a company want to go with Silverlight instead of Flex? Other than the obvious "not everyone has Silverlight", what are the pros and cons for each?

  • Wrapping a Flash/AS3 Sprite as a Flex MXML component

    - by John
    For my game, I am making the main game view as a plain Flash/AS3 class, something like: public class GameArena extends Sprite This is simply a big rectangle in which game objects are drawn, so no need for fancy UI and I want to keep the main game engine Flex-free so I can use Sprites rather than heavier Flex components. However for the entire game/app, I do still want to use Flex for GUI/layout. So I thought I could create a Flex class subclassing UIComponent, which has a GameView object as a child... now I can use this in MXML as a standard Flex component. e.g. public class ArenaView extends UIComponent { public var gameArena:GameArena; override protected function createChildren():void { super.createChildren(); if (!gameArena) { gameArena = new GameArena(); gameArena.width = 200; gameArena.height = 200; addChild(gameArena); } } } Then I have a simple line in my main App MXML like: <logic:Arena x="0" y="0" width="50%" height="100%" name="TestArenaPanel" /> But so far while my code compiles, the Flash class isn't getting rendered. Maybe it's something simple, but I wanted to ask if this is a reasonable approach, or there is something better? BTW: I've had the "should Flex be used" conversation many times. If you want to discuss that please do so in comments, but keep answers on topic.

  • Flex Spark DropDownList selectedItem didn't update after dataProvider changed

    - by Candy Chiu
    I have two dataProvider's for one DropDownList. The following code can be compiled and run. <?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" creationComplete="flipLast()" minWidth="955" minHeight="600"> <fx:Script> <![CDATA[ import mx.collections.ArrayCollection; public function flipLast():void { if( last ) { list.dataProvider = dp1; list.selectedItem = "Flex"; } else { list.dataProvider = dp2; list.selectedItem = "Catalyst"; } last = !last; } public var last:Boolean = true; public var dp1:ArrayCollection = new ArrayCollection( [ "Flex", "Air" ] ); public var dp2:ArrayCollection = new ArrayCollection( [ "Catalyst", "FlashBuilder" ] ); ]]> </fx:Script> <s:VGroup> <s:DropDownList id="list" requireSelection="true" /> <s:Label id="listSelectedItem" text="{list.selectedItem}" /> <s:Label id="listSelectedIndex" text="{list.selectedIndex}" /> <s:Button label="Flip" click="flipLast()" /> </s:VGroup> </s:Application> Scenario 1: dataProvider updated, but selectedIndex is the same. At startup: [ listSelectedItem=Flex, listSelectedIndex=1 ]. Click Flip: dataProvider is updated, but still [ listSelectedItem=Flex, listSelectedIndex=1 ]. Scenario 2: dataProvider updated, selectedIndex is also updated. At startup: [ listSelectedItem=Flex, listSelectedIndex=1 ]. Select Air from list: [ listSelectedItem=Air, listSelectedIndex=2 ]. Click Flip: dataProvider is updated, but still [ listSelectedItem=Catalyst, listSelectedIndex=1 ]. Seems to me that selectedItem is driven by selectedIndex. selectedItem updates only when selectedIndex updates. Shouldn't selectedItem be updated when dataProvider is updated? Is binding to selectedItem flawed?

  • Someone tell me why people writing GNU code use { like that?

    - by Deus Deceit
    I saw the rules on how to type code for UNITY project or GNU software in general. Why do they write code in such an ugly form? Is there a particular reason why they don't put brackets the way (from what I know) most people do? Why like this: for (i = 0; i < 5; i++) { //do something } and not like this: for (i = 0; i < 5; i++) { //Do something } or this: for(i = 0; i < 5l i++) { //Do Something } ???

  • Bash vs. Gnu screen : Replace Ctrl-A with Ctrl-Shift-A

    - by Stefan Lasiewski
    I'm a new user to GNU Screen. I've been using Bash for a very long time, and I want to give GNU Screen a try. As you know, GNU Screen uses 'C-a' (Control-A) as as the command character. Trouble is, this interferes with the Line Editing feature in Bash (and GNU Readline), because Control-A in Bash will Move to the start of the line." I know I can set the Command Character to another key sequence, like "^Q" or "``" (Backtick), but I have trouble finding another key sequence which isn't already in use (^Q is used by the terminal, backtick is used when writing shell scripts). It appears that the Command Character may only be one or two characters in length. Can I set the GNU Screen control character to be something like "Control-Shift-A"? (I can't use more then one hyperlink yet, so I cannot link to the Bash documentation)

  • How do I add color syntax highlighting to GNU emacs?

    - by Alex Reynolds
    I have two versions of emacs available to me on a locked workstation: $ /usr/local/bin/emacs --version GNU Emacs 22.3.1 $ /usr/bin/emacs --version GNU Emacs 21.4.1 In both cases, my terminal type is xterm when I run either version of emacs. When I run the v21 version of emacs, I get syntax coloring for Perl, HTML, and other modes. When I run the v22 version, I do not get syntax coloring. I would like to migrate from the v21 version because the combination of v21 emacs, GNOME Terminal and GNU Screen is eating Ctrl-arrow key chords, which prevents me from moving quickly between words. (OS X Terminal and GNU Screen do not have this issue.) The v22 version allows use of Ctrl-arrow key combinations with GNOME Terminal and GNU Screen. How do I fix the v22 version (or ask my sys admin to fix) so that it once again highlights syntax and allows me to use Ctrl-arrow key combinations?

  • Flex/PHP/XML data issue

    - by reado
    I have built a simple application in Flex. When the application loads, a GET request is made to the xmlService.php file with parameters "fetchData=letters". This tells the PHP to return the XML code. In Flex Debug I can see the XML data being sent by the PHP to the flex client. What I need it to do is populate the first drop down box (id="letter") with this data, however nothing is being received by Flex. I added an Alert.show() to check what was being returned but when the application runs, the alert is blank. Can anyone help? Thanks in advance.

  • What exactly is the GNU tar ././@LongLink "trick"?

    - by Cheeso
    I read that a tar entry type of 'L' (76) is used by gnu tar and gnu-compliant tar utilities to indicate that the next entry in the archive has a "long" name. In this case the header block with the entry type of 'L' usually encodes the name ././@LongLink . My question is: where is the format of the next block described? The format of a tar archive is very simple: it is just a series of 512-byte blocks. In the normal case, each file in a tar archive is represented as a series of blocks. The first block is a header block, containing the file name, entry type, modified time, and other metadata. Then the raw file data follows, using as many 512-byte blocks as required. Then the next entry. If the filename is longer than will fit in the space allocated in the header block, gnu tar apparently uses what's known as "the ././@LongLink trick". I can't find a precise description for it. When the entry type is 'L', how do I know how long the "long" filename is? Is the long name limited to 512 bytes, in other words, whatever fits in one block? Most importantly: where is this documented?

  • GNU Flex, multiline rule

    - by Simone Margaritelli
    Hi there i have a flex rule inside my lexer definition : operators "[]"|"[]="|"[]<"|".."|"."|".="|"+"|"+="|"-"|"-="|"/"|"/="|"*"|"*="|"%"|"%="|"++"|"--"|"^"|"^="|"~"|"&"|"&="|"|"|"|="|"<<"|"<<="|">>"|"!"|"<"|">"|">="|"<="|"=="|"!="|"&&"|"||"|"~=" Is there any way to split this ruole on more lines to keep it clearer? I tried with \ just like macros but it does not seem to be accepted by flex :( PS: I don't want to split the rule in more sub-rules, but only split its regex in more lines to keep the code clearer.

  • how to build GNU Classpath and JamVM

    - by michelemarcon
    I'm trying to build GNU Classpath 0.98 and JamVM 1.5.2. Following the JamVM readme, I did 'configure; make; make install' on the jamVM, and it worked. I then added jamvm and Sun javac to the path. Then with GNU Classpath I did this: ./configure --enable-jni --disable-gtk-peer --disable-gconf-peer --disable-plugin I got this error: The javac failed (see config.log) On the config.log, I see that javac can't find VMStackWalker (which is jamvm-specific) I added the jamvm classes to the CLASSPATH, then I got this error: The Java VM jamvm failed (see config.log) On the config.log, I see that jamvm cannot find java.lang.Class WTF?

  • How to catch all exceptions in Flex?

    - by Yaba
    When I run a Flex application in the debug flash player I get an exception pop up as soon as something unexpected happened. However when a customer uses the application he does not use the debug flash player. In this case he does not get an exception pop up, but he UI is not working. So for supportability reasons, I would like to catch any exception that can happen anywhere in the Flex UI and present an error message in a Flex internal popup. By using Java I would just encapsulate the whole UI code in a try/catch block, but with MXML applications in Flex I do not know, where I could perform such a general try/catch.

  • How can I define custom 'contentGroups' in a custom Flex 4 component?

    - by swidnikk
    The spark panel component for example can be written like this And its skin file will handle layout of the contentGroup, controlBarGroup, and titleDisplay. Notice, however that the contentGroup is doesn't appear in the code above and that the controlBarGroup accepts child mxml components. Now say I want to create a custom component that defines various required and non-required skinparts, such as 'headerGroup', 'navigationGroup', and 'accountPreferencesGroup'. I'd like to write this custom component like this The motivation here is that I can now create a couple different skin files to change the look and layout of those subgroups. Reading source of the spark panel, there are some calls within the mx_internal namespace such as getMXMLContent() which is a method of the spark group component, but which I have no access to. Does the description above make sense? How can I create custom 'contentGroups' in my custom Flex4 component that can use nested mxml child components? Should I approach this a different way?

  • flex debugger (how to retrieve a session variable set by a browser)

    - by Rees
    hello, i'm creating a flex application and trying to debug using the "Network Monitor" view. The script i'm debugging fetches a PHP session variable (the PHP outputs xml) and the actionscript retrieves the value from the HTTPService event. if I am using say a chrome browser, i can correctly retrieve the session variable ANY TIME. if I switch to say a firefox browser, then clearly the chrome session variable is unavailable to firefox. My issue is that I create the session variable with say chrome, and then try to retrieve my session variable from my FLEX application debugger (which always returns null) -when I really want it to return my session variable. is there a way for my flex debugger to retrieve this session variable set by chrome (or any browser)? (I'm even using chrome as my debugging browser for flex)

  • How do I get Flex Builder to use the selected framework?

    - by Michael Prescott
    I'm attempting to create a Flex Project that will cause the Flash Player to cache the Flex framework. Flex Builder comes with Flex SDK 3.2.0.3958 and setting the Framework Linkage to use Runtime shared Library (RSL) under Project Properties - Flex Build Path will separate the framework from my main application and I see that my project's bin-debug directory contains framework_3.2.0.3958.swf and *.swz for distribution. Flex SDK 3.4 fixes a few bugs, so I configured it as another available sdk and set it as the default SDK. When I compile, I expect the bin-debug directory to contain framework_3.4.0.9271.swf and *.swz; however, Flex Builder is still writing framework_3.2.0.3958.swf and *.swz. How do I configure Flex Builder to package the correct framework files for Flash Player caching?

  • tabIndex fails in an AS3 swf loaded into a flex app

    - by quoo
    I feel like I'm missing something really simple here. I'm loading a AS3 swf containing a form (created by one of our designers) into a flex app. The swf's tabIndex properties work fine when the swf is viewed by itself, however, once it's loaded into the flex app: <mx:SWFLoader source="form.swf" top="20" horizontalCenter="0" id="formSwf" complete="swfCompleteHandler(event)"/> the form fields stop receiving focus on tab. I've been looking at the FocusManager in flex, for some sort of solution, but I can't seem to find any examples, and I'm not entirely sure I'm looking in the right place. Am I stuck redoing this form in flex?
