  • What are good memory management techniques in Flash/as3

    - by Parris
    Hello! So I am pretty familiar with memory management in Java, C and C++; however, in flash what constructs are there for memory management? I assume flash has a sort of virtual machine like java, and I have been assuming that things get garbage collected when they are set to null. I am not sure if this is actually the case though. Also is there a way to force garbage collection in Flash? Any other tips? Thanks

  • Merge functionality of two xsl files into a single file (not a xsl import or include issue)

    - by anuamb
    I have two xsl files; both of them perform different tasks on source xml one after another. Now I need a single xsl file which will actually perform both these tasks in single file (its not an issue of xsl import or xsl include): say my source xml is: <LIST_R7P1_1 <R7P1_1 <LVL2 <ORIG_EXP_PRE_CONV#+# <EXP_AFT_CONVabc <GUARANTEE_AMOUNT#+# <CREDIT_DER/ </LVL2 <LVL21 <AZ#+# <BZbz1 <AZaz2 <BZ#+# <CZ/ </LVL21 </R7P1_1 </LIST_R7P1_1 My first xsl (tr1.xsl) removes all nodes whose value is blank or null: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:if test=". != '' or ./@* != ''"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:if> <xsl:template </xsl:stylesheet The output here is <LIST_R7P1_1 <R7P1_1 <LVL2 <ORIG_EXP_PRE_CONV#+# <EXP_AFT_CONVabc <GUARANTEE_AMOUNT#+# </LVL2 <LVL21 <AZ#+# <BZbz1 <AZaz2 <BZ#+# </LVL21 </R7P1_1 </LIST_R7P1_1 And my second xsl (tr2.xsl) does a global replace (of #+# with text blank'') on the output of first xsl: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" <xsl:template name="globalReplace" <xsl:param name="outputString"/ <xsl:param name="target"/ <xsl:param name="replacement"/ <xsl:choose <xsl:when test="contains($outputString,$target)"> <xsl:value-of select= "concat(substring-before($outputString,$target), $replacement)"/> <xsl:call-template name="globalReplace"> <xsl:with-param name="outputString" select="substring-after($outputString,$target)"/> <xsl:with-param name="target" select="$target"/> <xsl:with-param name="replacement" select="$replacement"/> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$outputString"/> </xsl:otherwise> </xsl:choose </xsl:template <xsl:template match="text()" <xsl:template match="@*|*"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> </xsl:stylesheet So my final output is <LIST_R7P1_1 <R7P1_1 <LVL2 <ORIG_EXP_PRE_CONV <EXP_AFT_CONVabc <GUARANTEE_AMOUNT </LVL2 <LVL21 <AZ <BZbz1 <AZaz2 <BZ </LVL21 </R7P1_1 </LIST_R7P1_1 My concern is that instead of these two xsl (tr1.xsl and tr2.xsl) I only need a single xsl (tr.xsl) which gives me final output? Say when I combine these two as <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" <xsl:template match="@*|node()" <xsl:if test=". != '' or ./@* != ''"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:if> <xsl:template name="globalReplace" <xsl:param name="outputString"/ <xsl:param name="target"/ <xsl:param name="replacement"/ <xsl:choose <xsl:when test="contains($outputString,$target)"> <xsl:value-of select= "concat(substring-before($outputString,$target), $replacement)"/> <xsl:call-template name="globalReplace"> <xsl:with-param name="outputString" select="substring-after($outputString,$target)"/> <xsl:with-param name="target" select="$target"/> <xsl:with-param name="replacement" select="$replacement"/> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$outputString"/> </xsl:otherwise> </xsl:choose </xsl:template <xsl:template match="text()" <xsl:call-template name="globalReplace" <xsl:with-param name="outputString" select="."/ <xsl:with-param name="target" select="'#+#'"/ <xsl:with-param name="replacement" select="''"/ </xsl:call-template </xsl:template <xsl:template match="@|" <xsl:copy <xsl:apply-templates select="@*|node()"/ </xsl:copy </xsl:template </xsl:stylesheet it outputs: <LIST_R7P1_1 <R7P1_1 <LVL2 <ORIG_EXP_PRE_CONV <EXP_AFT_CONVabc <GUARANTEE_AMOUNT <CREDIT_DER/ </LVL2 <LVL21 <AZ <BZbz1 <AZaz2 <BZ <CZ/ </LVL21 </R7P1_1 </LIST_R7P1_1 Only replacement is performed but not null/blank node removal.

  • Django shows too many warnings when deleting an object

    - by valya
    Hello! I have two models: class Account(models.Model): main_request = models.ForeignKey('JournalistRequest', related_name='main_request') key = models.CharField(_('Key'), max_length=100) class JournalistRequest(models.Model): account = models.ForeignKey(Account, blank=True, null=True) When I try to delete a JournalistRequest, It shows warning with a lot of nesting, like Are you sure you want to delete the selected ?????? ??? objects? All of the following objects and their related items will be deleted: Journalist Request: some request Account: some account Journalist Request: some request Account: some account Journalist Request: some request Account: some account Journalist Request: some request Account: some account Journalist Request: some request All accounts are the same one (ids are same), and all requests are the same one, so I think it becaues of a recursion. But I have no idea how to solve this problem in Django 1.1.1! Can you help me?

  • Red-Black trees - Erasing a node with two non-leaf children

    - by SalamiArmi
    Hi all, I've been implementing my own version of a red-black tree, mostly basing my algorithms from Wikipedia (http://en.wikipedia.org/wiki/Red-black_tree). Its fairly concise for the most part, but there's one part that I would like clarification on. When erasing a node from the tree that has 2 non-leaf (non-NULL) children, it says to move either side's children into the deletable node, and remove that child. I'm a little confused as to which side to remove from, based on that. Do I pick the side randomly, do I alternate betweek sides, or do I stick to the same side for every future deletion?

  • Displaying Video using a Window Handle

    - by fergs
    I'm working on a C# wrapper for Dallmeier camera's and currently have a working wrapper. I can connect to a camera via passing the window handle (in my application its a picture box handle), this is used to send video and messages. Once connected I can then send the StartLiveView command and then a live stream video will be shown in the picture box. Can someone explain how this works by just giving the window handle? And how can I grab an Image from this stream when Picturebox1.Image is null?

  • Capture window close event

    - by -providergordienko.vladimir
    I want to capture events that close editor window (tab) in Visual Studio 2008 IDE. When I use dte2.Application.Events.get_CommandEvents(null, 0).BeforeExecute I successfully captured such events: File.Close File.CloseAllButThis File.Exit Window.CloseDocumentWindow and others. If code in window is not acceptable, I stop the event (CancelDefault = true). But if I click "X" button on the right hand side, "Save Changes"; dialog appears, tab with editor window close and I have no any captured events. In this case I can capture WindowClosing event, but can not cancel the event. Is it poosible to handle "x" button click and stop event?

  • Build XML document using Linq To XML

    - by JasonDR
    Given the following code: string xml = ""; //alternativley: string xml = "<people />"; XDocument xDoc = null; if (!string.IsNullOrEmpty(xml)) { xDoc = XDocument.Parse(xml); xDoc.Element("people").Add( new XElement("person", "p 1") ); } else { xDoc = new XDocument(); xDoc.Add(new XElement("people", new XElement("person", "p 1") )); } As you can see, if the xml variable is blank, I need to create the rood node manually, and append the person the root node, whereas if it is not, I simple add to the people element My question is, is there any way to generically create the document, where it will add all referenced node automatically if they do not already exists?

  • TelerikProfileProvider with custom Membership Provider

    - by Larsenal
    I've setup two membership providers: my custom provider and the Sitefinity provider. My custom membership provider is set as the default. I want to use Sitefinity's Profile provider for both sets of users. However, the profile provider only seems to work for the users that I pull out of the Sitefinity membership provider. After poking around with Reflector a bit, it seems that the Telerik Profile Provider assumes that the username exists in its own DB. User userByName = this.Application.GetUserByName(userName); if (userByName != null) { // magic happens here... } All the magic only happens if it was able to retrieve the user locally. Seems to violate the principles of the providers. Shouldn't I be able to arbitrarily add properties to any user regardless of the membership provider? (I've also posted this on the Sitefinity forum, but haven't got a response yet. SO has spoiled me. I've come to expect an answer in minutes, not days.)

  • Catch isn't working

    - by neoneye
    I'm baffled. What could be causing 'catch' not to be working and how do I fix it? <?php try { throw new Exception('BOOM'); error_log("should not happen"); } catch(Exception $e) { error_log("should happen: " . $e->getMessage()); } ?> Actual output [27-Apr-2010 09:43:24] PHP Fatal error: Uncaught exception 'Exception' with message 'BOOM' in /mycode/exception_problem/index.php:4 Stack trace: #0 {main} thrown in /mycode/exception_problem/index.php on line 4 Desired output should happen: BOOM PHP version 5.2.3 In php_info() I don't see anywhere exceptions could have been disabled. I have tried with "restore_exception_handler();" but that doesn't make the catch block working. I have also tried with "set_exception_handler(NULL);" but that neither make the catch block working. How do I get the desired output?

  • missing event when using modules with requirejs

    - by ali haider
    I had javascript code in a single JS file that was working fine (using XHR/AJAX). When I split it up into separate modules in a requirejs application, I do not seem to get a handle on the event object & it shows up as undefined (testing in firefox 29.0.1). Calling module: ajax.onreadystatechange = new ajaxResponse().handleAjaxResponse(e); ajaxResponse define(["require", './url/urlCommon'], function(require, urlCommon) { 'use strict'; var ajaxResponse = function() { var ajax = null; // e = event || window.event; this.handleAjaxResponse = function() { if (typeof event === 'undefined') { var event = event || window.event; } console.log('e is now:' + typeof e); I also do not have a handle on the event in the handleAjaxResponse method (error: undefined). Any thoughts on what I need to do to troubleshoot/fix this will be greatly appreciated.
