  • Debugging dynamically added Javascript code

    - by gilm
    One of the programmers I worked with has something similar in code: var head = document.getElementsByTagName("head")[0]; var e = document.createElement("script"); e.type = "text/javascript"; var b = "function moo() { alert('hello'); }"; e.appendChild(document.createTextNode(b)); head.appendChild(e); moo(); This is all good and dandy, but I would like to step into moo(), and firebug just can't do that. I know I can rip the whole thing apart, but I reallllly don't want to touch it and his code works :) Any ideas how I can debug this with Firebug? Cheers

  • Anything wrong with this php code?

    - by Hwang
    1st I have to say I know nothing bout php. I was actually doing my AS3 guest-book and through parts of tutorials from Activetut, I managed to come out a flash guest-book. So the problem now I'm facing is the guest-book could only inject 1 XML data and it will always clear off the old 1, while the flash is still caching on the old XML files. I'd found some other tutorials(which I think its quite hard since i dunno anything about php) and comparing to the php code I'm using, it seems to be extremely short. I have no idea what the code does, so currently I'm not sure whether the problems came from the php or my AS3. <?php if (isset($GLOBALS["HTTP_RAW_POST_DATA"])){ $xml = $GLOBALS["HTTP_RAW_POST_DATA"]; $file = fopen("wish.xml","wb"); fwrite($file, $xml); fclose($file); } ?> and below is my correct XML format: <WISHES> <WISH> <NAME>Test</NAME> <EMAIL>[email protected]</EMAIL> <DATENTIME>2/3/10</DATENTIME> <MESSAGE>Dummy Message</MESSAGE> </WISH> <WISH> <NAME>Test</NAME> <EMAIL>[email protected]</EMAIL> <DATENTIME>2/3/10</DATENTIME> <MESSAGE>Dummy Message</MESSAGE> </WISH> </WISHES> So anyone kind to explain what that php code does? cause it replace my XML with: <WISH> <NAME>Test</NAME> <EMAIL>[email protected]</EMAIL> <DATENTIME>2/3/10</DATENTIME> <MESSAGE>Dummy Message</MESSAGE> </WISH>

  • Hy, problem mantaining big javascript code.

    - by Totty
    I have more than 1000 lines in a big jquery plugin, that is actually a big class, that inludes some others classes, but they have to be in the same file. I inlcude a piece of code. If you have another way to simplify the code.. The actual problem is that i have a gallery with a lot of things, is dynamic with smart ajax data loading so it requires a lot of classes to use it properly and to cache the data. (function($){ var TottysGallery = function(element, options, data){ var Core = new function(){...}; var Core2 = new function(){...}; var Core3 = new function(){...}; var Core = function(){...}; };

  • Need an encrypted online source code backup service.

    - by camelCase
    Please note this is not a question about online/hosted SVN services. I am working on a home based, solo developer, project that now has commercial significance and it is time to think about remote source code backup. There is no need for file level check in/out, all I need is once a day or once a week directory level snapshot to remote storage. Automatic encryption would be a bonus to protect my IP. What I have in mind is some sort of GUI interface app that will squirt a source code snapshot off to an Amazon S3 bucket on an automatic schedule. (My development PC runs on MS Windows.)

  • Downloading Eclipse's Source Code

    - by digiarnie
    I'm doing a study on large Java projects and would like to view the source code for Eclipse. I have gone to this url (http://wiki.eclipse.org/index.php/CVS_Howto) and figured that the most useful cvs repository for me to look at would be this one: :pserver:[email protected]:/cvsroot/eclipse (The Eclipse platform project) However, when looking at this repository, it has so many modules! Which modules should I be trying to check out? I don't necessarily want to build the IDE from source, however, I just want to get the core Eclipse code base to perform some analysis. Would I just check out any modules starting with "org.eclipse..."? Should I be checking out any of the others? Or is there an easier way to get the source? I read somewhere that you can get the source from the binary version of Eclipse but I am unsure where to find the source.

  • Is it possible to compile IronRuby code to a .NET assembly (EXE or DLL)

    - by Chris Ammerman
    My scenario consists of the following points. I have a packaged software product I am developing in C# Since it is a packaged product, the public interfaces of the assemblies need to be tightly controlled... All assemblies are strong-named Any classes that don't absolutely have to be "public" are "internal" I want to write unit tests for those "internal" classes, since they are the bulk of the code And finally.... I want to try writing the unit tests in Ruby. Since the unit tests would be external to the assembly containing the code under test, the assemblies under test would each need to have an "InternalsVisibleTo" attribute specifying the name of the unit test assembly. Which of course would mean that the Ruby unit tests would have to compile down to a .NET assembly so they can be given access in this way. Can this be done? If so, how? All I can find on the web about "compiling IronRuby" is about building the actual IronRuby runtime from source.

  • Swing code in sockets

    - by asb
    I am learning swings for making GUI. I was thinking which is the best possible way in case of socket with swings. 1. The whole swing code goes in the server file. All the handlers and logic in on server side. Client only create socket. 2. The server have logic part. The code for the swing to display interface goes on client side. Client Creates stream to send / rec. data from server. Whch is the good way out of 2 ?

  • IFrame causing javascript code to not execute

    - by Claudio Redi
    Does anyone know why this code doesn't work. This means, the alert is NOT fired <iframe/> <script type="text/javascript">alert('hello');</script> While this code with the alert BEFORE the Iframe works perfeclty. This means the alert is fired <script type="text/javascript">alert('hello');</script> <iframe/> Seems that no javascript placed after the iframe is executed, I don't find any logic to this.

  • Abstract out repeated code

    - by CookieMonster
    The code in this event is repeated exactly in two other event handlers. How do I put the repeated code into a method and call that method from the event handlers so I only have to maintain it in one place? I'm not sure how to pass the event args to the calling method. protected void gvDocAssoc_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { if ((Convert.ToString(DataBinder.Eval(e.Row.DataItem, "DETAIL_TYPE_DESC")) == "Transcript") && (Convert.ToString(DataBinder.Eval(e.Row.DataItem, "INSTITUTION_CODE")) == "")) { e.Row.BackColor = System.Drawing.Color.Red; } if ((Convert.ToString(DataBinder.Eval(e.Row.DataItem, "DETAIL_TYPE_DESC")) == "Certified Diploma") && (Convert.ToString(DataBinder.Eval(e.Row.DataItem, "INSTITUTION_CODE")) == "")) { e.Row.BackColor = System.Drawing.Color.Red; } if ((Convert.ToString(DataBinder.Eval(e.Row.DataItem, "DOC_TYPE_DESC")) == "Post Graduate conditions") && (Convert.ToString(DataBinder.Eval(e.Row.DataItem, "INSTITUTION_CODE")) == "")) { e.Row.BackColor = System.Drawing.Color.Red; } } }

  • Rhino - Set FEATURE_LOCATION_INFORMATION_IN_ERROR in code?

    - by Scott
    I'd like fileName, lineNumber and stack traces to automatically be provided by Rhino for any errors. I've been told that I need to set FEATURE_LOCATION_INFORMATION_IN_ERROR on the current context, but I'm not sure how to do this in code. Does anybody have an example of turning this feature on so that I can see stacktrace dumps on crashes? I'm using Rhino as part of Narwhal/Jack, and so that complicates things a bit, and I think the easiest way to at least get moving forward is if I can set it through code. Thanks.

  • Optimizing Haskell code

    - by Masse
    I'm trying to learn Haskell and after an article in reddit about Markov text chains, I decided to implement Markov text generation first in Python and now in Haskell. However I noticed that my python implementation is way faster than the Haskell version, even Haskell is compiled to native code. I am wondering what I should do to make the Haskell code run faster and for now I believe it's so much slower because of using Data.Map instead of hashmaps, but I'm not sure I'll post the Python code and Haskell as well. With the same data, Python takes around 3 seconds and Haskell is closer to 16 seconds. It comes without saying that I'll take any constructive criticism :). import random import re import cPickle class Markov: def __init__(self, filenames): self.filenames = filenames self.cache = self.train(self.readfiles()) picklefd = open("dump", "w") cPickle.dump(self.cache, picklefd) picklefd.close() def train(self, text): splitted = re.findall(r"(\w+|[.!?',])", text) print "Total of %d splitted words" % (len(splitted)) cache = {} for i in xrange(len(splitted)-2): pair = (splitted[i], splitted[i+1]) followup = splitted[i+2] if pair in cache: if followup not in cache[pair]: cache[pair][followup] = 1 else: cache[pair][followup] += 1 else: cache[pair] = {followup: 1} return cache def readfiles(self): data = "" for filename in self.filenames: fd = open(filename) data += fd.read() fd.close() return data def concat(self, words): sentence = "" for word in words: if word in "'\",?!:;.": sentence = sentence[0:-1] + word + " " else: sentence += word + " " return sentence def pickword(self, words): temp = [(k, words[k]) for k in words] results = [] for (word, n) in temp: results.append(word) if n > 1: for i in xrange(n-1): results.append(word) return random.choice(results) def gentext(self, words): allwords = [k for k in self.cache] (first, second) = random.choice(filter(lambda (a,b): a.istitle(), [k for k in self.cache])) sentence = [first, second] while len(sentence) < words or sentence[-1] is not ".": current = (sentence[-2], sentence[-1]) if current in self.cache: followup = self.pickword(self.cache[current]) sentence.append(followup) else: print "Wasn't able to.

  • Windows Store App Visual Basic Rotate Object with code

    - by Ajay Raghav
    How to rotate an ellipse (or any other object) with VB code? In XAML, I designed an ellipse and easily rotated it from the properties (Transform - Rotate - Angle). When I am trying to do it with VB code, I cannot locate the rotate/angle property of that ellipse. So, I tried this: Dim Rotator As RotateTransform Rotator.Angle = 90 Ellipse1.RenderTransform = Rotator It didn’t work. It says: Unable to cast object of type 'Windows.UI.Xaml.Media.MatrixTransform' to type 'Windows.UI.Xaml.Media.RotateTransform'. I think I’m close to the right way. Please give me a push. Thanks

  • XSLT: Disable output escaping in an entire document.

    - by Kragen
    I'm trying to generate some C# code using xslt - its working great until I get to generics and need to output some text like this: MyClass<Type> In this case I've found that the only way to emit this is to do the following: MyClass<xsl:text disable-output-escaping="yes">&lt;</xsl:text>Type<xsl:text disable-output-escaping="yes">&gt;</xsl:text> Where: Often it all needs to go on one line, otherwise you end up with line breaks in the generated code In the above example I technically could have used only 1 <xsl:text />, however usually the type Type is given by some other template, e.g: <xsl:value-of select="@type" /> I don't mind having to write &lt; a lot, but I would like to avoid writing <xsl:text disable-output-escaping="yes">&lt;</xsl:text> for just a single character! Is there any way of doing disable-output-escaping="yes" for the entire document?

  • How to write this JavaScript code without eval?

    - by karlthorwald
    How to write this JavaScript code without eval? var typeOfString = eval("typeof " + that.modules[modName].varName); if (typeOfString !== "undefined") { doSomething(); } The point is that the name of the var that I want to check for is in a string. Maybe it is simple but I don't know how. Edit: Thank you for the very interesting answers so far. I will follow your suggestions and integrate this into my code and do some testing and report. Could take a while. Edit2: I had another look at the could and maybe itis better I show you a bigger picture. I am greatful for the experts to explain so beautiful, it is better with more code: MYNAMESPACE.Loader = ( function() { function C() { this.modules = {}; this.required = {}; this.waitCount = 0; this.appendUrl = ''; this.docHead = document.getElementsByTagName('head')[0]; } function insert() { var that = this; //insert all script tags to the head now! //loop over all modules: for (var modName in this.required) { if(this.required.hasOwnProperty(modName)){ if (this.required[modName] === 'required') { this.required[modName] = 'loading'; this.waitCount = this.waitCount + 1; this.insertModule(modName); } } } //now poll until everything is loaded or //until timout this.intervalId = 0; var checkFunction = function() { if (that.waitCount === 0) { clearInterval(that.intervalId); that.onSuccess(); return; } for (var modName in that.required) { if(that.required.hasOwnProperty(modName)){ if (that.required[modName] === 'loading') { var typeOfString = eval("typeof " + that.modules[modName].varName); if (typeOfString !== "undefined") { //module is loaded! that.required[modName] = 'ok'; that.waitCount = that.waitCount - 1; if (that.waitCount === 0) { clearInterval(that.intervalId); that.onSuccess(); return; } } } } } }; //execute the function twice a second to check if all is loaded: this.intervalId = setInterval(checkFunction, 500); //further execution will be in checkFunction, //so nothing left to do here } C.prototype.insert = insert; //there are more functions here... return C; }()); var myLoader = new MYNAMESPACE.Loader(); //some more lines here... myLoader.insert();

  • Convert the ada code to its C .

    - by maddy
    HI All, I have a piece of ada code shown below which is a simple switch case statements.Is there any better way to convert this into C. for I in 1..100 loop case I is when 100 => Dollars := Dollars + 1; when 25|50|75 => Quarters := Quarters + 1; when 10|20|30|40|60|70|80|90 => Dimes := Dimes + 1; when 5|15|35|45|55|65|85|95 => Nickles := Nickles + 1; when others => Pennies := Pennies + 1; end case; end loop; Now by adding the switch and the case for each values in the case,i can do that conversion,But it seems tyo make the code too big.Is there anywa other simple and compact way.Please get back to me if the question is not clear?

  • Flash: Adjust this code to keep the duplicated movie clip

    - by Luke Evans
    OK, so here is my code ham_mc.onPress=function(){ startDrag(this); } ham_mc.onRelease=ham_mc.onReleaseOutside=function(){ stopDrag(); _root.ham_mc.duplicateMovieClip("ham_mc" + "x",2); x++; } The user can at first drag the movie clip. When released, the duplicateMovieClip command runs, leaving a new ham movie clip in the position the first is dragged to. PROBLEM: When I click and drag the first ham movie click again, the duplicateMovieClip runs again but REPLACES the previous generated movie clip. I added x and x++ in an attempt to give the movie clip duplication a different name every time, but this doesn't solve it. How do I change this code so that a NEW ham_mc is created every time, rather than overwriting the old one. I'm tired, sorry for the poor explaination!

  • Default taglibs used within included JSPs for editing

    - by lostiniceland
    Hello everyone Within Eclipse's jsp-editor, as you all know, I get code-assistance for external taglibs once I defined them. In the project I am working on now a lot of jsps are just included and have no taglib definition in the top which gives me a lot of editor warnings. In the deployment this doesnt matter because the taglibs are defined in the head-jsp. Is there a way that I can define default taglibs within a project so the eclipse editor will give me code-assist even though I dont include the taglib in each file again?

  • Setting a "dependency property" in code

    - by Matt B
    I'm on a roll today... I have the following code delaring a dependency property inside a class called ActionScreen: #region Dependency Properties & Methods public string DescriptionHeader { get { return (string)GetValue(DescriptionHeaderProperty); } set { SetValue(DescriptionHeaderProperty, value); } } // Using a DependencyProperty as the backing store for DescriptionHeader. This enables animation, styling, binding, etc... public static readonly DependencyProperty DescriptionHeaderProperty = DependencyProperty.Register("DescriptionHeader", typeof(string), typeof(ActionScreen), new UIPropertyMetadata("xxx")); #endregion I bind to this property in my Xaml as so: <GridViewColumn DisplayMemberBinding="{Binding Description}" Header="{Binding DescriptionHeader}" Width="350" /> Now I want to be able to set the parameter from my code behind when I recieve an event - but it's not working: public string DescColText { set { this.Dispatcher.Invoke(DispatcherPriority.Normal, new Action(delegate() { DescriptionHeader = value; })); } }

  • Javascript code inside updatepanel usercontrol.

    - by Ed Woodcock
    Ok: I've got an updatepanel on an aspx page that contains a single Placeholder. Inside this placeholder I'm appending one of a selection of usercontrols depending on certain external conditions (this is a configuration page). In each of these usercontrols there is a bindUcEvents() javascript function that binds the various jQuery and javascript events to buttons and validators inside the usercontrol. The issue I'm having is that the usercontrol's javascript is not being recognised. Normally, javascript inside an updatepanel is executed when the updatepanel posts back, however none of this code can be found by the page (I've tried running the function manually via firebug's console, but it tells me it cannot find the function). Does anyone have any suggestions? Cheers, Ed. EDIT: cut down (but functional) example: Markup: <script src="/js/jquery-1.3.2.min.js"></script> <form id="form1" runat="server"> <div> <asp:ScriptManager ID="Script" runat="server" /> <asp:Button ID="Postback" runat="server" Text="Populate" OnClick="PopulatePlaceholder" /> <asp:UpdatePanel ID="UpdateMe" runat="server"> <Triggers> <asp:AsyncPostBackTrigger ControlID="Postback" EventName="Click" /> </Triggers> <ContentTemplate> <asp:Literal ID="Code" runat="server" /> <asp:PlaceHolder ID="PlaceMe" runat="server" /> </ContentTemplate> </asp:UpdatePanel> </div> </form> C#: protected void PopulatePlaceholder(object sender, EventArgs e) { Button button = new Button(); button.ID = "Push"; button.Text = "push"; button.OnClientClick = "javascript:return false;"; Code.Text = "<script type=\"text/javascript\"> function bindEvents() { $('#" + button.ClientID + "').click(function() { alert('hello'); }); } bindEvents(); </script>"; PlaceMe.Controls.Add(button); }

  • Add UIView behind UITableView in UITableViewController code

    - by Drew C
    I would like to use a fixed image as the background in a simple grouped table view in my iPhone program. Unfortunately, no matter what I do, the background is always solid white. I have followed several supposed solutions on this site and others to no avail. Here is the relavant code in the viewDidLoad method of the table view controller class (note, this code uses a solid blue color rather than an image for simplicity's sake): self.tableView.opaque = NO; self.tableView.backgroundColor = [UIColor clearColor]; UIView *backgroundView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; backgroundView.backgroundColor = [UIColor blueColor]; [self.tableView.window addSubview:backgroundView]; [backgroundView release]; I suspect that I am not positioning the backgroundView view in the right place. I have tried sendToBack:, bringToFront:, and others but I always just get a white background. Is it possible to do this from within the UITableViewController? Must I use Interface Builder?
