  • ASP.NET MVC AJAX value not displaying

    - by mazhar kaunain baig
    View: function success(arg) { var obj = arg.get_response().get_object(); if (obj.ErrorMessage === '') { var answer = document.createElement('div'); answer.appendChild(document.createTextNode(obj.Answer)); document.getElementById('answers').appendChild(answer); } else { document.getElementById('errors').innerHTML = obj.ErrorMessage; } } <% using (Ajax.BeginForm("EditOrganizationMeta", "Organization", new AjaxOptions { HttpMethod = "POST", OnSuccess = "success" })) { %> <input type="submit" name="button<%=OrganizationMeta.vcr_MetaKey + Lang.int_LangId %>" value="Save" /> <div id="errors"></div> <div id="answers"></div> <% } %> Controller: [HttpPost] [ValidateInput(false)] public ActionResult EditOrganizationMeta(FormCollection collection) { return Json(new { Answer = "Record Successfully Saved", ErrorMessages = "Title is required" }); } The thing is that success method in the javascript is not getting the required parameters. It is printing undefined there. Is there a problem in javascript method OnSuccess?

  • Some math and animation

    - by Ockonal
    Hello, I have a grass texture: I use it in my 2d-game. I want to animate it by code, without any predefined animations. The grass should interact with wind. So when the wind is stronger, the grass should stoop into need side more. First version of animation I made using sinusoid function, but such animation is a bit ugly, because the base of the grass moves left/right like all another part of picture. And with sinusoid I'm not able to regulate stoop of the image. Any advices?

  • jquery li with image fade in background (fade in class)

    - by steve
    I'm currently using this code: var gallery = $('ul#gallery').children(); $(gallery).filter(':even').not(':last').hover(function () {$(this).toggleClass('next')}); I'm trying to make it fade this new class in. Currently, there's an <li> with an image in it, no background. When the 'next' class is added, it gives it a background image when hovered over. Is there a way to just fade in the new class without making the image blink/fade at all? Thanks.

  • Conky graph frozen in time

    - by dijxtra
    Is it possible to plot a graph in conky? Give a function a set of values 0-100 and conky plots a graph similar to execgraph? What I want is to visualize how a variable changed in last week. For example, I'd like to make a graph of gold prices in last 14 days. One way I could do that is use "execigraph 86400 python fetch_price_of_gold.py" and keep my box up 24/7 and eventually I'd get a nice graph. But, unfortunately my box isn't up 24/7. Not to mention I'd have to wait 14 days after every reboot ;-) So, any other ideas? :-)

  • Good way to edit the previous defined class in ipython

    - by leo
    Hi, I am wondering a good way to follow if i would like to redefine the members of a previous defined class in ipython. say : I have defined a class intro like below, and later i want to redefine part of the function definition _print_api. Any way to do that without retyping it . class intro(object): def _print_api(self,obj): def _print(key): if key.startswith('_'): return '' value = getattr(obj,key) if not hasattr(value,im_func): doc = type(valuee).__name__ else: if value.__doc__ is None: doc = 'no docstring' else: doc = value.__doc__ return ' %s :%s' %(key,doc) res = [_print(element) for element in dir(obj)] return '\n'.join([element for element in res if element != '']) def __get__(self,instance,klass): if instance is not None: return self._print(instance) else: return self._print_api(klass)

  • [C#, Regex] EOL Special Char not matching

    - by Aurélien Ribon
    Hello, I am trying to find every "a - b, c, d" pattern in an input string. The pattern I am using is the following : "^[ \t]*(\\w+)[ \t]*->[ \t]*(\\w+)(,[ \t]*\\w+)*$" The input is : a -> b b -> c c -> d The function is : private void ParseAndBuildGraph(String input) { MatchCollection mc = Regex.Matches(input, "^[ \t]*(\\w+)[ \t]*->[ \t]*(\\w+)(,[ \t]*\\w+)*$", RegexOptions.Multiline); foreach (Match m in mc) { Debug.WriteLine(m.Value); } } The output is : c -> d Actually, there is a problem with the line ending "$" special char. If I insert a "\r" before "$", it works, but I thought "$" would match any line termination (with the Multiline option), especially a \r\n in a Windows environment. Is it not the case ?

  • Actionscript 3 Navigate with Keyboard Between Labels

    - by Sbml
    Hello I need to navigate between labels with arrow keys like a power point presentation. I have an array with labels and a KeyboardEvent. My problem is, if I am in label number four for example and click in arrow click, always goes to first label. So I need help defining my current label to go to the next on key press. My code: import flash.events.KeyboardEvent; var myLabels:Array = [ "label_1", "label_2", "label_3", "label_4"]; var nextLabel:String; var inc:int = 0; stage.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed); function keyPressed(evt:KeyboardEvent):void { switch(evt.keyCode) { case Keyboard.RIGHT : nextLabel = String(myLabels[inc]); gotoAndStop(nextLabel); inc++; break; } } Thanks

  • Geocoding autocomplete bias not working

    - by chris
    I'm using the following code to get the autocomplete functionality for an address input box using Google Maps API v3: function initializeAutocomplete() { var defaultBounds = new google.maps.LatLngBounds( new google.maps.LatLng(1.484016,103.575212), new google.maps.LatLng(1.233592,104.033618)); var input = document.getElementById('destStreet'); var myOptions = {bounds: defaultBounds, types: ['geocode']}; autocomplete = new google.maps.places.Autocomplete(input, myOptions); } The problem is that biasing doesn't seem to work as the first results are usually not relevant to the defined bounds (a country). I've seen a few apps working fine, so I'm wondering where the problem is. I came across the JQuery autocomplete plugin (http://code.google.com/p/geo-autocomplete/) which would seem like a good alternative since it has a region filter, but I'm unable to "install it" or use it because of my very limited knowledge (I learn by example). Could you please help me getting more relevant results with the above code or guide me through the implementation of the JQuery alternative? Of course I'm very open to other suggestions as well.

  • SQL Server Multiple Joins Are Taxing The CPU

    - by durilai
    I have a stored procedure on SQL Server 2005. It is pulling from a Table function, and has two joins. When the query is run using a load test it kills the CPU 100% across all 16 cores! I have determined that removing one of the joins makes the query run fine, but both taxes the CPU. Select SKey From dbo.tfnGetLatest(@ID) a left join [STAGING].dbo.RefSrvc b on a.LID = b.ESIID left join [STAGING].dbo.RefSrvc c on a.EID = c.ESIID Any help is appreciated, note the join is happening on the same table in a different database on the same server.

  • Google Chrome + Ajax

    - by teehoo
    Im writing an ajax web app that uses Comet/Long Polling to keep the webpage up to date, and I noticed in Chrome, it treats the page as if its always loading (icon for the tab keeps spinning). I thought this was normal for Google Chrome + Ajax because even Google Wave had this behaviour. Well today I noticed that Google Wave no longer keeps the loading icon spinning, anyone know how they fixed this? Here's my ajax call code var xmlHttpReq = false; // Mozilla/Safari if (window.XMLHttpRequest) { xmlHttpReq = new XMLHttpRequest(); } // IE else if (window.ActiveXObject) { xmlHttpReq = new ActiveXObject("Microsoft.XMLHTTP"); } xmlHttpReq.open('GET', myURL, true); xmlHttpReq.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xmlHttpReq.onreadystatechange = function() { if (xmlHttpReq.readyState == 4) { updatePage(xmlHttpReq.responseText); } } xmlHttpReq.send(null);

  • what is order notation f(n)=O(g(n))?

    - by Lopa
    2 questions: question 1: under what circumstances would this[O(f(n))=O(k.f(n))] be the most appropriate form of time-complexity analysis? question 2: working from mathematical definition of O notation, show that O(f(n))=O(k.f(n)), for positive constant k.? My view: For the first one I think it is average case and worst case form of time-complexity. am i right? and what else do i write in that? for the second one I think we need to define the function mathematically, so is the answer something like because the multiplication by a constant just corresponds to a readjustment of value of the arbitrary constant 'k' in definition of O.

    This is only a problem in IE. the following actionscript is for a simple preloader for a movie i'm working on.

  • Python: How do I create a reference to a reference?

    - by KCArpe
    Hi, I am traditionally a Perl and C++ programmer, so apologies in advance if I am misunderstanding something trivial about Python! I would like to create a reference to a reference. Huh? Ok. All objects in Python are actually references to the real object. So, how do I create a reference to this reference? Why do I need/want this? I am overriding sys.stdout and sys.stderr to create a logging library. I would like a (second-level) reference to sys.stdout. If I could create a reference to a reference, then I could create a generic logger class where the init function receives a reference to a file handle reference that will be overrided, e.g., sys.stdout or sys.stderr. Currently, I must hard-code both values. Cheers, Kevin

  • MFMailComposerViewController doesn't always display attachments

    - by davbryn
    I'm attaching a few files to an email to export from the application I've written, namely a .pdf and a .png. I create these by rendering some view to a context and creating an image and a pdf. I can validate that the files are created properly (I can confirm this by looking in my apps sandbox from Finder, and also by sending the email. I receive the files correctly.) The problem I'm getting is that larger files don't have a preview generated for them within the MFMailComposerViewController view (I simply get a blue icon with a question mark). Is there a limitation on file sizes that can be attached in order for preview to function correctly? With small files it works as expected, but if I try and attach a pdf with the following properties: Pages: 1 Dimensions: 2414 x 1452 Size: 307 KB the file is generated correctly, but displays the question mark icon. If there is no way around that, can I remove the attachment preview altogether? Many thanks, Bryn

  • Thread safety of Matlab engine API

    - by Jeremy
    I have discovered through trial and error that the MATLAB engine function is not completely thread safe. Does anyone know the rules? Discovered through trial and error: On Windows, the connection to MATLAB is via COM, so the COM Apartment threading rules apply. All calls must occur in the same thread, but multiple connections can occur in multiple threads as long as each connection is isolated. From the answers below, it seems that this is not the case on UNIX, where calls can be made from multiple threads as long as the calls are made serially.

  • VB in Access: Combo Box Values are not visible in form view but are visible through Debug.Print

    - by Thor
    Code in Form onLoad: country_combo.RowSourceType = "Value List" Code in a reset function: Dim lListIndex As Long With Me.country_combo For lListIndex = .ListCount - 1 To 0 Step -1 .RemoveItem (lListIndex) Next lListIndex<br/> End With Code to populate country combo: *For n = 1 To numCountries* *countryCombo.AddItem (countryRS.Fields("countryName"))* *countryRS.MoveNext* *Next n* I'm having a problem that occurs AFTER the code to populate the country combobox runs. The values are there as I can run Debug.Print(countryCombo.Value) and it prints out the name of the selected country, but I can't see the values in the combobox at all. They're invisible, and as far as I know there is no visiblity property for specific items, unless I'm completely mistaken.

  • How's my pygame code?

    - by Isaiah
    I'm still getting the hang of lots of things and thought I should post some code I made with pygame and get some feedback^^. I posted code here: http://urlvars.com/code/snippet/39272/my-bouncing-program http://urlvars.com/code/snippet/39273/my-bouncing-program-classes There's tome things that I implemented that I'm not using yet I just realized like a timer at the bottom of the main while loop. If my code isn't readable, I'm sorry, I'm self taught and this is the first code I've ever posted anywhere. By the way I made some variables that take the screensize and half it to find a point to spit out the squares, but when I try to use it, it makes a weird effect :/ Try switching the list i have in the newbyte() function with the halfScreen variable and see it freak out o.O thank you

  • Recursive vs. Iterative algorithms

    - by teehoo
    I'm implementing the Euclidian algorithm for finding the GCD (Greatest Common Divisor) of two integers. Two sample implementations are given: Recursive and Iterative. http://en.wikipedia.org/wiki/Euclidean_algorithm#Implementations My Question: In school I remember my professors talking about recursive functions like they were all the rage, but I have one doubt. Compared to an iterative version don't recursive algorithms take up more stack space and therefore much more memory? Also, because calling a function requires uses some overhead for initialization, aren't recursive algorithms more slower than their iterative counterpart?

  • String labels on boxplot outliers

    - by Benoît Collette
    Hi! I want to put string labels on outliers in a boxplot. Here's a simplification of the dataset I'm using: [,x] [,y] [,z] 7 2 a 10 2 b 112 3 c boxdata<-boxplot(x ~ y) To put values as label on outliers by group, I use this function: for(i in 1:length(boxdata$group)){ text(boxdata$group[i], boxdata$out[i], which(x==boxdata$out[i]),labels=boxdata$out[i],pos=4) } The problem is that I want to put z (string) as label instead of outlier value, but I don't know how to proceed. What do I need to do? Thank you! Ben

  • my version of strlcpy

    - by robUK
    Hello, gcc 4.4.4 c89 My program does a lot of string coping. I don't want to use the strncpy as it doesn't nul terminate. And I can't use strlcpy as its not portable. Just a few questions. How can I put my function those its paces to ensure that it is completely safe and stable. Unit testing? Is this good enough for production? size_t s_strlcpy(char *dest, const char *src, const size_t len) { size_t i = 0; /* Always copy 1 less then the destination to make room for the nul */ for(i = 0; i < len - 1; i++) { /* only copy up to the first nul is reached */ if(*src != '\0') { *dest++ = *src++; } else { break; } } /* nul terminate the string */ *dest = '\0'; /* Return the number of bytes copied */ return i; } Many thanks for any suggestions,
