I have tried if(grade.text doubleValue] == 0){ //Not a number } but then it still can accept "23f". Thanks

  • What real life bad habits has programming given you? [closed]

    - by Jacob T. Nielsen
    Programming has given me a lot of bad habits and it continues to give me more everyday. But I have also gotten some bad habits from the mindset that I have put myself in. There simply are some things that are deeply rooted in my nature, though some of them I wish I could get rid of. A few: Looking for polymorphism, inheritance and patterns in all of God's creations. Explaining the size of something in pixels and colors in hex code. Using code related abstract terms in everyday conversations. How have you been damaged?

  • "Right" way to deallocate an std::vector object

    - by Jacob
    The first solution is: std::vector<int> *vec = new std::vector<int>; assert(vec != NULL); // ... delete vec; An alternative is: std::vector<int> v; //... vec.clear(); vec.swap(std::vector<int>(vec)); The second solution's a bit of a trick --- what's the "right" way to do it?

  • Fast (de)serialization on iPhone

    - by Jacob Kuypers
    I'm developing a game/engine for iPhone OS. It's the first time I'm using Objective-C. I made my own binary format for geometry data and for textures I'm focusing on PVRTC. That should be the optimal approach as far as speed and space are concerned. I really want to keep loading time to a minimum and - if possible - be able to save very fast as well. So now I'm trying to make my "Entity" stuff persistent without sacrificing performance. First I wanted to use NSKeyedArchiver. From what I've heard, it's not very fast. Also, what I want to serialize is mostly structs made of floats with some ints and strings, so there isn't really a need for all that "object graph" overhead. NSArchiver would have been more appropriate, but they kicked that off the iphone for some reason. So now I'm thinking about making my own serialization scheme again. Am I wrong in thinking that NSKeyedArchiver is slow (I only read that, haven't tested it myself)? If so, what's the best way to encode/decode structs (with no pointers, mostly floats) without sacrificing speed?

  • Global mouseMove

    - by Jacob Kofoed
    I have made the following javascript to be used in my jQuery based website. What it does, is to move a slider up/down, and scale the item above higher/smaller. Everything works fine, but since the slider is only a few pixels in height, and the move event is a bit slow (it does not trigger for every pixel) so when I move the mouse fast, the slider can't hold on and the mouse get's out of the slider item. The mouseMove event won't be triggered no more since it is bound to the slider. I guess everything could be fixed by setting the mouseMove global to the whole site, but it won't work, or at least I don't know how to make that work. Should it be bound to document, or body? here is my current code for the slider: $.fn.resize = function (itemToResize) { MinSize = 100; MaxSize = 800; pageYstart = 0; sliderMoveing = false; nuskriverHeight = 0; this.mousedown(function(e) { pageYstart=e.pageY; sliderMoveing = true nuskriverHeight = parseFloat((itemToResize).css('height')); }); this.mouseup(function() { sliderMoveing = false }); this.mousemove(function(e) { if (sliderMoveing) { (itemToResize).css('height', (nuskriverHeight + (e.pageY - pageYstart))); if (parseFloat( (itemToResize).css('height')) > MaxSize) { (itemToResize).css('height', MaxSize) }; if (parseFloat( (itemToResize).css('height')) < MinSize) { (itemToResize).css('height', MinSize) }; }; }); }; Thanks for any help, is much appreciated

  • C++ and C#, "Casting" Functions to Delegates, What's the scoop?

    - by Jacob G
    In C# 2.0, I can do the following: public class MyClass { delegate void MyDelegate(int myParam); public MyClass(OtherObject obj) { //THIS IS THE IMPORTANT PART obj.SomeCollection.Add((MyDelegate)MyFunction); } private void MyFunction(int myParam); { //... } } Trying to implement the same thing in C++, it appears I have to do: MyDelegate del = gcnew MyDelegate(this, MyFunction); obj-SomeCollection-Add(del); Obviously I can create a new instance of the delegate in C# as well instead of what's going on up there. Is there some kind of magic going on in the C# world that doesn't exist in C++ that allows that cast to work? Some kind of magic anonymous delegate? Thanks.

  • Using jQuery, how to modify text outside of tags?

    - by Jacob
    Given a string of text that is both adjacent to a span and inside of a div, what are some methods to modify just that text, leaving the surrounding HTML intact? For example: <div id="my-div">modify this text<span id="my-span"></span></div> I have tried things like $('#my-div').html(function(i, elem){blah;}); but this seems to cause the span to be deleted and a new span to be added, because some styling is lost. I realize that it would be best to wrap the text string in its own HTML tags before applying client-side code, but that is out of my control.

  • Apply [ThreadStatic] attribute to a method in external assembly

    - by Sen Jacob
    Can I use an external assembly's static method like [ThreadStatic] method? Here is my situation. The assembly class (which I do not have access to its source) has this structure public class RegistrationManager() { private RegistrationManager() {} public static void RegisterConfiguration(int ID) {} public static object DoWork() {} public static void UnregisterConfiguration(int ID) {} } Once registered, I cannot call the DoWork() with a different ID without unregistering the previously registered one. Actually I want to call the DoWork() method with different IDs simultaneously with multi-threading. If the RegisterConfiguration(int ID) method was [ThreadStatic], I could have call it in different threads without problems with calls, right? So, can I apply the [ThreadStatic] attribute to this method or is there any other way I can call the two static methods same time without waiting for other thread to unregister it? If I check it like the following, it should work. for(int i=0; i < 10; i++) { new Thread(new ThreadStart(() => Checker(i))).Start(); } public string Checker(int i) { public static void RegisterConfiguration(i); // Now i cannot register second time public static object DoWork(i); Thread.Sleep(5000); // DoWork() may take a little while to complete before unregistered public static void UnregisterConfiguration(i); }

  • Can I attach data gathered by a form to a file that is being uploaded?

    - by Jacob
    I need customers to upload files to my website and I want to gather their name or company name and attach it to the file name or create a folder on the server with that as the name so we can keep the files organized. Using PHP to upload file PHP: if(isset($_POST['submit'])){ $target = "upload/"; $file_name = $_FILES['file']['name']; $tmp_dir = $_FILES ['file']['tmp_name']; try{ if(!preg_match('/(jpe?g|psd|ai|eps|zip|rar|tif?f|pdf)$/i', $file_name)) { throw new Exception("Wrong File Type"); exit; } move_uploaded_file($tmp_dir, $target . $file_name); $status = true; } catch (Exception $e) { $fail = true; } } Other PHPw/form: <form enctype="multipart/form-data" action="" method="post"> input type="hidden" name="MAX_FILE_SIZE" value="1073741824" /> label for="file">Choose File to Upload </label> <br />input name="file" type="file" id="file" size="50" maxlength="50" /><br /> input type="submit" name="submit" value="Upload" /> php if(isset($status)) { $yay = "alert-success"; echo "<div class=\"$yay\"> <br/> <h2>Thank You!</h2> <p>File Upload Successful!</p></div>"; } if(isset($fail)) { $boo = "alert-error"; echo "<div class=\"$boo\"> <br/> <h2>Sorry...</h2> <p>There was a problem uploading the file.</p><br/><p>Please make sure that you are trying to upload a file that is less than 50mb and an acceptable file type.</p></div>"; }

  • Allocated Private Bytes keeps going up in one computer but not the other

    - by Jacob
    OK, this may sound weird, but here goes. There are 2 computers, A (Pentium D) and B (Quad Core) with almost the same amount of RAM. If I run the same code on both computers, the allocated private bytes in A never goes down resulting in a crash later on. In B it looks like the private bytes is constantly deallocated and everything looks fine. In both computers, the working set is deallocated and allocated similarly. Could this be an issue with manifests or DLLs (system)? I'm clueless. Note: I observed the utilized memory with Process Explorer.

  • Comments on this assumption about running on dev server vs a real instance in app engine (python)?

    - by Jacob Oscarson
    Hello app engineers! I'm on an app engine project where I'd like to put in a link to a Javascript test runner that I'd like to only exist when running the development server. I've made some experiments on a local shell with configuration loaded using the technique found in NoseGAE versus live on the 'App Engine Console' [1] and it looks to me like a distinction btw real instance and dev server is the presence of the module google.appengine.tools. Which lead me to this utility function: def is_dev(): """ Tells us if we're running under the development server or not. :return: ``True`` if the code is running under the development server. """ try: from google.appengine import tools return True except ImportError: return False The question (finally!) would be: is this a bad idea? And in that case, can anyone suggest a better approach? [1] http://con.appspot.com/console/ (try it! very handy indeed)

  • Simple oracle backup without using exp or expdp

    - by Jacob
    I have Oracle 10g installed on Windows in C:\oracle. If I stop all Oracle services, is it safe to backup by just copying the entire directory (e.g., to C:\oracle_bak), or am I significantly better off using expdp? Pointers to docs/websites very welcome, I wasn't able to Google up anything relevant.

  • finding links that are hyper-links in jQuery

    - by Jacob Lowe
    Im trying to take a link either when clicked or hover over be able to grab the attribute href and tell if its a hyper-link or not. Also i want it to be able to tell me if its a hyper-link to my own site. Plus various other filters. The main purpose for this is so that when a internal link is clicked it will tell ajax to grab the content, alot of my links are generated (via wordpress)so I can't modify them too much. Another purpose for this is so i can also make all external links open on a new window. I have a solution that works on a simple test page but when i put into a working page it breaks. I know i am probably making this harder then it should be. Here is my code $(function(){ $('a').live('click', function(){ var x = $(this).attr('href'); $(this).parent('div').append('<div id="test">' + x +'</div>'); $('#test:contains("http")').css('color', 'red'); $('#test:contains("sitename")').css('color', 'black'); $('#test:contains("admin")').css('color', 'red'); if($('#test').css('color') == 'red'){ alert('external link'); $('#test').remove(); return true; }else{ alert('external link'); $('#test').remove(); return false; } }); }); thanks for you help

  • ASP MVC ViewData from one view to another (Html.Encode())

    - by Jacob Huggart
    Hello all, I have a page with a bunch of labels and checkboxes on it. On this page, the labels need to be easily customizable after the project is deployed. So I made all of the labels in this style: Html.Encode(ViewData["lblText"]) And I added a button on the page called "Edit Button Labels" that will only be seen by admins. When that button is clicked, I would like to load another view that simply contains a table of two columns. One column needs to contain the current labels and the other should have text boxes for the user to enter new labels. Then, once any changes have been made, I need to permanently change the "lblText" for each label on the original page. I have tried passing viewdata and tempdata to the "Edit Button Labels" view using both return view() and return RedirectToAction() with no success. Am I missing something minor or is there a better way to do this?

    Hi everyone, I lost over 35 hours' worth of code today. I don't know how it happened, but it just did. And I'm extremely upset about it. I learned the hard way that version control / backups are the most important. Anyone want to share your similar experiences?
