  • very weird problem concerning date and time in silverlight + ria services

    - by Patrick LHM
    Hello Friends i'm facing a very weird problem in sliverlight 4 + RIA Services, or maybe it's not weird and i'm just a newbie anyway i hope someone here can help, the problem is the following i've created a function on the server side inside the domain service this function is very simple and has a line in it that adds the server current date and time to the database (it's an HR application and employees should sign in and out thrue it each from it's own pc ) Emp.TimeOut = system.DateTime.now (C# syntax) the weird part is that for some users it always adds 3 hours to the current time(exp if he signes out at 5 it shows 8) and for others it works perfectly. the server and all the stations in the company have exactly the same time settings and the same time zone, and anyway my fucntion is on the server side so it should no be realted to the users time. any ideas why this is happening ? i've bin trying to find out why for days now but with no luck

  • How to split up a long list using \n

    - by pypy
    Here is a long string that I convert to a list so I can manipulate it, and then join it back together. I am having some trouble being able to have an iterator go through the list and when the iterator reach, let us say every 5th object, it should insert a '\n' right there. Here is an example: string = "Hello my name is Josh I like pizza and python I need this string to be really really long" string = string.split() # do the magic here string = ' '.join(string) print(string) Output: Hello my name is Josh I like pizza and python I need this string to be really really long Any idea how i can achieve this? I tried using: for words in string: if words % 5 == 0: string.append('\n') but it doesn't work. What am I missing?

  • Need help with jQuery UI Accordion navigationFilter option

    - by theJBRU
    I'm building an accordion for navigation. Each section of the accordion has a set of links. The firing code looks like this: $(document).ready(function() { $(".selector").accordion({ collapsible: true, active: false, navigation: true }); }); This all worked fine and dandy until one of the links in each set was edited to point to a single file, call it foo.html. So now if you navigate to foo.html, the location.href matches every section of the accordion (since each section has a link to it) and that opens all the sections, defeating the purpose of the accordion. So I'm pretty sure I need to use the navigationFilter option but I've googled the living hell out of it and haven't found any examples of how to build the function associated with it. Help me, Stack Overflow!

  • template pass by const reference

    - by 7vies
    Hi, I've looked over a few similar questions, but I'm still confused. I'm trying to figure out how to explicitly (not by compiler optimization etc) and C++03-compatible avoid copying of an object when passing it to a template function. Here is my test code: #include <iostream> using namespace std; struct C { C() { cout << "C()" << endl; } C(const C&) { cout << "C(C)" << endl; } ~C() { cout << "~C()" << endl; } }; template<class T> void f(T) { cout << "f<T>" << endl; } template<> void f(C c) { cout << "f<C>" << endl; } // (1) template<> void f(const C& c) { cout << "f<C&>" << endl; } // (2) int main() { C c; f(c); return 0; } (1) accepts the object of type C, and makes a copy. Here is the output: C() C(C) f<C> ~C() ~C() So I've tried to specialize with a const C& parameter (2) to avoid this, but this simply doesn't work (apparently the reason is explained in this question). Well, I could "pass by pointer", but that's kind of ugly. So is there some trick that would allow to do that somehow nicely? EDIT: Oh, probably I wasn't clear. I already have a templated function template<class T> void f(T) {...} But now I want to specialize this function to accept a const& to another object: template<> void f(const SpecificObject&) {...} But it only gets called if I define it as template<> void f(SpecificObject) {...}

  • "Intercepting" user input into text box and removing it

    - by James P
    I have a text box that I would like to do some validation on. At the moment I have this code: function updateChanger() { // Validate input var likeMessage = validateInput($("#like").val()); alert(likeMessage); } function validateInput(input) { input = input.replace(/[^a-zA-Z0-9:\(\/\)\s\.,!~]/g, ""); return input; } This successfully trims out unwanted characters in the likeMessage variable, but the character still gets entered into the text box. I would like to stop that from happening. I know it will have something to do with $("#like").val() but the only thing I can think of is just chopping off the end character from the text box value, would this suffice? Thanks for any help!

  • How can I determine which dependency would cause a C++ compilation unit to be rebuilt?

    - by Seb Rose
    I have a legacy C++ application with a deep graph of #includes. Changes to any header file often cause recompiles of seemingly unrelated source files. The application is built using a Visual Studio 2005 solution (sln) file. Can MSBUILD be invoked in a way that it reports which dependency(ies) are causing a source file to be recompiled? Is there any other tool that might be able to help? NOTE: I'm only looking for a tool to tell me why a file would be rebuilt, not some restrospective magic telling me why it was rebuilt.

  • What's the fastest way to approximate the period of data using Octave?

    - by John
    I have a set of data that is periodic (but not sinusoidal). I have a set of time values in one vector and a set of amplitudes in a second vector. I'd like to quickly approximate the period of the function. Any suggestions? Specifically, here's my current code. I'd like to approximate the period of the vector x(:,2) against the vector t. Ultimately, I'd like to do this for lots of initial conditions and calculate the period of each and plot the result. function xdot = f (x,t) xdot(1) =x(2); xdot(2) =-sin(x(1)); endfunction x0=[1;1.75]; #eventually, I'd like to try lots of values for x0(2) t = linspace (0, 50, 200); x = lsode ("f", x0, t) plot(x(:,1),x(:,2)); Thank you! John

    - by aspdotnetuser
    Hi, I want to use jQuery to make a call to a c# web service called CheckUserName.ashx which checks whether that username is valid and returns an error message as a string. How can I use to jQuery to do this?

  • thumbs.db messing up my upload routine

    - by Scott B
    I'm getting the following error while uploading a zip archive. Warning: ZipArchive::extractTo(C:\xampplite\htdocs\testsite/wp-content/themes/mytheme//styles\mytheme/Thumbs.db) [ziparchive.extractto]: failed to open stream: Permission denied in C:\xampplite\htdocs\testsite\wp-content\themes\mythem\uploader.php on line 17 The thing I can't quite figure is that I don't see a thumbs.db file in either the zip archive or the destination folder that was created (the upload still processes, I just get these errors). The function is below, line 17 is commented... function openZip($file_to_open) { global $target; $zip = new ZipArchive(); $x = $zip->open($file_to_open); if($x === true) { $zip->extractTo($target); //this is line 17 $zip->close(); unlink($file_to_open); } else { die("There was a problem. Please try again!"); } }

  • Lambda expressions and nullable types

    - by Mathew
    I have two samples of code. One works and returns the correct result, one throws a null reference exception. What's the difference? I know there's some magic happening with capturing variables for the lambda expression but I don't understand what's going on behind the scenes here. int? x = null; bool isXNull = !x.HasValue; // this works var result = from p in data.Program where (isXNull) select p; return result.Tolist(); // this doesn't var result2 = from p in data.Program where (!x.HasValue) select p; return result2.ToList();

  • If free() knows the length of my array, why can't I ask for it in my own code?

    - by Chris Cooper
    I know that it's a common convention to pass the length of dynamically allocated arrays to functions that manipulate them: void initializeAndFree(int* anArray, int length); int main(){ int arrayLength = 0; scanf("%d", &arrayLength); int* myArray = (int*)malloc(sizeof(int)*arrayLength); initializeAndFree(myArray, arrayLength); } void initializeAndFree(int* anArray, int length){ int i = 0; for (i = 0; i < length; i++) { anArray[i] = 0; } free(anArray); } but if there's no way for me to get the length of the allocated memory from a pointer, how does free() "automagically" know what to deallocate? Why can't I get in on the magic, as a C programmer? Where does free() get its free (har-har) knowledge from?

  • Getting camera preview data without using a preview callback

    - by velocipedestrian
    I have an app that does some processing to camera preview frames before displaying them to the user. I'm currently using preview callbacks to access the image data, but the problem I have is that the onPreviewFrame() function stops getting called if you start recording video using a MediaRecorder, and I want the processing to continue when video is being recorded. I've tried doing the following: public static Bitmap convertViewToBitmap(View view) { Bitmap bitmap = Bitmap.createBitmap(view.getWidth(),view.getHeight(), Bitmap.Config.ARGB_8888); view.draw(new Canvas(bitmap)); return bitmap; } to convert the preview surface to a bitmap, but when I pass the preview SurfaceView to the function it returns an all-black bitmap (it works when I test it on normal views though). Is there any other way I can access the image data if preview callbacks are not available?

  • Backbone.js - Getting JSON back from url

    - by Brian
    While trying to learn Backbone.js, I've been trying to grab the content of a JSON file using the following code: (function($){ var MyModel = Backbone.Model.extend(); var MyCollection = Backbone.Collection.extend({ model : MyModel, url: '/backbone/data.json', parse: function(response) { console.log(response); return response; } }); var stuff = new MyCollection; console.log(stuff.fetch()); console.log(stuff.toJSON()); })(jQuery) 'stuff.fetch()' returns the entire object (with the data I'm after in responseText), 'stuff.toJSON' returns nothing ([]), but the console in the parse method is returning exactly what I want (the json object of my data). I feel like I'm missing something obvious here, but I just can't seem to figure it out why I can't get the right data out. Could someone point me in the right direction or show me what I'm doing wrong here? Am I using a model for the wrong thing?

  • How do I prevent form from redirecting after submission?

    - by Noor
    I have searched the site and I've found various solutions, most of them suggesting using return false; Problem is that I'm using this piece of code to submit the form: $(function() { $("#snd").click(function() { var dendar = "http://" + $("#inpt").val() + ":" + $("#pwd").val() + "secretsite.lol/something.xml"; $("#formen").attr("action", dendar); $("#formen").submit(); alert(dendar); return false; }); }); The alert is just there to let me know that the form has been submitted.. Thanks guys!

  • Set Page Output Cache VaryByCustom value programmatically

    - by Chris Marisic
    I want to use an Enum value for the types of VaryByCustom parameters I will support, is it possible to do this? I tried setting it in the page itself <%@ OutputCache Duration="600" VaryByParam="none" VaryByCustom='<%=VaryByCustomType.IsAuthenticated.ToString(); %>' %> But this returned the entire literal string "<%=VaryByCustomType.IsAuthenticated.ToString(); %>" inside my global.asax is there any way to do this either on the page itself or from the codebehind? Or is this just something I have to accept is purely magic strings and nothing I can do to add type safety to it?

  • Interesting Row_Number() bug

    - by Joel Coehoorn
    I was playing with the Stack Exchange Data Explorer and ran this query: http://odata.stackexchange.com/stackoverflow/q/2828/rising-stars-top-50-users-ordered-on-rep-per-day Notice down in the results, rows 11 and 12 have the same value and so are mis-numbered, even though the row_number() function takes the same order by parameter as the query. I know the correct fix here is to specify an additional tie-breaker column in the order by clauses, but I'm more curious as to why/how the row_number() function returned different results on the same data? If it makes a difference anywhere, this runs on Azure.

    I have jQuery code that loads images with jQuery load method. It works perfectly in all other browsers, except in IE.
