  • jQuery ajax request to php, how to return plain text only

    - by jyoseph
    I am making an ajax request to a php page and I cannot for the life of me get it to just return plain text. $.ajax({ type: 'GET', url: '/shipping/test.php', cache: false, dataType: 'text', data: myData, success: function(data){ console.log(data) } }); in test.php I am including this script to get UPS rates. I am then calling the function with $rate = ups($dest_zip,$service,$weight,$length,$width,$height); I am doing echo $rate; at the bottom of test.php. When viewed in a browser shows the rate, that's great. But when I request the page via ajax I get a bunch of XML. Pastie here: http://pastie.org/1416142 My question is, how do I get it so I can just return the plain text string from the ajax call, where the result data will be a number? Edit, here's what I see in Firebug- Response tab: HTML tab:

  • Can CSS change the apparent sequence of elements, e.g. using float or position?

    - by ChrisW
    Edit: answer to this question is easy, a simple example of float left and float right. I'd like to float some annotations to the left of a topic using HTML and CSS, for example the 'status' and 'author' annotations shown in the following mockup/image: For semantic reasons, perhaps: I prefer to use CSS instead of a table-based layout In the HTML, the status should appear after the corresponding heading For example: <h1>This is a section title</h1> <div class="status">approved</div> <div class="author">chris</div> <p>This is some text. Lorem ipsum.</p> <p>Lorem ipsum.</p> <h1>Different section title</h1> <div class="status">rejected</div> <p>Lorem ipsum.</p> I'd like the annotations to be after the heading in the HTML, because everything associated with (i.e. the contents of) a topic is usually whatever is after the topic's heading. However I'd like the annotations to be displayed before (to the left of) the heading, as illustrated above. Is this possible? What is the most semantic HTML, and corresponding CSS, that will render as shown above? Would you recommend a table-based layout instead? Even if that means putting the headings in a table cell? It may not be possible; this answer suggests it isn't possible ... but I don't know CSS well enough to say that for sure.

  • Generic calls to OnResetDevice() and OnLostDevice()

    - by bobobobo
    This is kind of a COM question to do with DirectX. So, both ID3DXSprite and ID3DXFont and a bunch of the other ID3DX* objects require you to call OnLostDevice() when the d3d device is lost AND OnResetDevice() when the device is reset. What I want to do is maintain an array of all ID3DX* objects and simply call OnResetDevice() and OnLostDevice() on each whenever the device is lost or reset. However I can't seem to find a BASE CLASS for the ID3DX* classes... they all seem to COM-ually inherit from IUnknown. Is there a way to do this or do I have to maintain separate arrays of ID3DXFont* pointers, ID3DXSprite* pointers, etc?

  • How to rotate a drawable with anti-aliasing enabled

    - by Mike
    I need to rotate an ImageView by a few degrees. I'm doing this by subclassing ImageView and overloading onDraw() @Override protected void onDraw(Canvas canvas) { canvas.save(); canvas.scale(0.92f,0.92f); canvas.translate(14, 0); canvas.rotate(1,0,0); super.onDraw(canvas); canvas.restore(); } The problem is that the image that results shows a bunch of jaggies. How can I antialias an ImageView that I need to rotate in order to eliminate jaggies? Is there a better way to do this?

  • Strip text of all formatting on paste

    - by griegs
    I have an application that allows the user to create an article. The problem arises when the user pastes from something like Word which comes loaded with a bunch of markup. I'm using a jQuery editor called tiny_mce which allows the markup. I do a htmlencode and decode obviously but it means that i carry a huge payload of markup. Is there a way to strip (all) markup from pasted text and just keep the text? Or is there a way that tiny_mce can show the markup as text?

  • Sending variables in URLs in PHP with echo

    - by alexpelan
    Hi all, I can't really find good guidelines through google searches of the proper way to escape variables in URLs. Basically I am printing out a bunch of results from a mysql query in a table and I want one of the entries in each row to be a link to that result's page. I think this is easy, that I'm just missing a apostrophe or backslash somewhere, but I can't figure it out. Here's the line that's causing the error: echo "<a href = \"movies.php/?movie_id='$row['movie_id']'\"> Who Owns It? </a> "; and this is the error I'm getting: Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING If you could elaborate in your answers about general guidelines for working with echo and variables in urls, that would be great. Thanks.

  • Sync two SqlExpress using NHibernate

    - by Christian
    Hello, I am creating a simple project management system which uses NHibernate for object storage. The underlying database is SQL express (at least currently for development). The client runs on either the desktop or laptop. I know I could use web-services and store the DB only on the desktop, but this would force the desktop to be available all the time. I am currently thinking about duplicating the DB, having two instances with "different data". To clarify, we are not talking about a productive app here, its a prototype. One way to achieve this very simple would be the following process: Client: Check if desktop DB is available (through web service) Client: If yes, use desktop storage, no problem here Client: If not, use own DB as storage Client: Poll desktop regulary, as soon as it comes on, sync Client: Switch to desktop storage ... Desktop: Do not attempt any DB operation before checking for required sync Desktop: If sync needed, do it... My question is now, how would you sync? Assume 4 or 5 types of objects, all have GUID as identifiers. Would you always manually "lazy load" all objects of a certain type and feed them to the DB. Would you always drop the whole desktop DB in case the client DB may be newer and out of sync? Again, I want to stress out, I am not assuming any conflicts or stale data, I basically just want to "copy the whole DB from the client". Would you use NHibernate for this? Or would you separate the copy process? When I think about it, my questions comes down to this: Is there any function from NHibernate: SyncDBs_SourceWins_(SourceDB, TargetDB) Thanks for help, Chris

  • Shared WCF client code between .NET and Silverlight apps?

    - by Eduardo Scoz
    I'm developing a .NET application that will have both a WinForms and a Silverlight client. Although the majority of code will be in the server, I'll need to have quite a bit of logic in the clients as well, and I would like to keep the client library code the same. From what I could figure out so far, I need to have two different project types, a class library and a Silverlight class library, and link the files from one project to the other. This seems kind of lame, but it works for simple code. My problem, though, is that the code generated by the SVCUtil.exe to access WCF services is different from the code generated by the slsvcutil.exe, and the silverlight code is actually incompatible with the .NET one: I get a bunch of problems with the System.ServiceModel.Channel classes when I try to import the class into .NET. Has anybody done anything similar to this before? What am I doing wrong?

  • .NET XML Serialization, possibly to use a different method name than PropertySpecified for ignoring

    - by Lasse V. Karlsen
    I have a bunch of classes that I intend to serialize in order to transport over a webservice call. These classes already have properties that return whether a given "real" property has a value or not, that is ingrained in a lot of code of our product. Is it possible, for instance through attributes, for me to specify that each "real" property should be included if a specified other property returns true, but not one that is called RealPropertyNameSpecified? ie. for instance if I have this class: [XmlType("test")] public class TestClass { [XmlIgnore] public bool NameHasGotAValue { get; set; } [XmlElement("name")] public string Name { get; set; } } Is it possible for me to use the NameHasGotAValue as the "*Specified" method for the Name property, or is my only option to either rename NameHasGotAValue, add a NameSpecified method, or implement IXmlSerializable?

  • Client / Server security from mobile to website

    - by Amir Latif
    Hey. Am new to the world of web programming and learning a bunch of fairly simple new pieces of tech, trying to piece them all together. So, we have a simple client (currently iPhone, to move to J2ME soon) that's pulling down lists of data via PHP, which is talking to a MySQL db. I have a rudimentary user/login system so that data is only served to someone who matches a known user etc, either on the website or on the client. All the php scripts on the website that query the DB check to make sure an active session is in place, otherwise dumping the user back to the login screen. I've read a little about SSL and want to know if that is sufficient to protect the website AND the data passing between the server and the client?

  • Cannot customize Solution Explorer project context menu in VS 2010

    - by mikoro
    I'm trying to customize that context menu which comes up when you right click the project in the Solution Explorer. When I goto: Tools - Customize - Commands - Context Menu (radio button) - Project and Solution Context Menus | Project (drop down) I get nothing in the "controls:" list. I can modify other context menus starting with "Project and Solution Context Menus" but none of them is the right one. Any ideas? Currently I have ReSharper, PowerTools and StyleCop installed, but I have installed and uninstalled bunch of other addins (dotTrace, CodeIt.Right, VisualHG, DevExpress, random stuff from Extension Manager).

  • new image makes http request even though cached?

    - by joshs
    I have a javascript slide show that creates the next slide dynamically and then moves it into view. Since the images are actually sprites, the src is transparent.png and the actual image is mapped via background:url(.. in css. Everytime (well, most of the time) the script creates a new Element, Firefox makes an http request for transparent.png. I have a far-future expires header, and Firefox is respecting all other files' expiries. Is there a way to avoid these unnecessary requests. Even though the server is returning 304 unmodified responses, it would be nice if Firefox would respect the expiries on dynamically created images. I suspect that if I injected a simple string instead of using new Element, this might solve the problem, but I use some methods on Prototypes extended Element object, so I would like to avoid a bunch of html strings in my js file. This is a nit-picky question, but I'm working on front-end optimization now, so I thought I would address it. Thanks.

  • Hiding text under an image for SEO purposes

    - by JCHASE11
    I am going to use a large image on my page with a bunch of text on it. The reason I am including body text on an image is because the text will be rotated, and there currently isn't any GREAT solution for rotating text seamlessly across all browsers. On this image, there is a lot of text, and I want it to be indexed by search engines. (but its a picture so it's content won't be indexed, obviously) If I was to include a div with all the text html and set the css to display:none, would Google still index the content that is hidden under the picture? Are their any other solid solutions here?

  • Custom XAML property

    - by Scott Silvi
    Hey all - I've seen a library that allows me to do this inside my XAML, which sets the visibility of the control based on whether or not the user is in a role: s:Authorization.RequiresRole="Admin" Using that library with my database requires a bunch of coding that I can't really do right now. Ultimately here's what I want to know... I have received the authenticated users role from my SPROC, and its currently stored in my App.xaml.cs as a property (not necessary for the final solution, just FYI for now). I want to create a property (dependency property? attached property?) that allows me to say something very similar to what the other library has: RequiresRole="Admin", which would collapse the visibility if the user is not in the Admin role. Can anyone point me in the right direction on this? Thanks, Scott

  • How do I correctly use generics?

    - by ninjasense
    I basically am making webrequests and recieving a JSON response. Depending on the request, I am parsing JSON request into objects I have created. The parsing is pretty much the same no matter what the object Im parsing into looks like. So I have a bunch of methods doing the same work only with different objects, I was wondering how I could accomplish this with generics? Here is an example public static ArrayList<Contact> parseContacts(String responseData) { ArrayList<Contact> Contacts = new ArrayList<Contact>(); try { JSONArray jsonContacts = new JSONArray(responseData); if (!jsonContacts.isNull(0)) { for (int i = 0; i < jsonContacts.length(); i++) { Contacts.add(new Contact(jsonContacts.getJSONObject(i))); } } } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (Exception e) { } return Contacts; }

  • Side effects of reordering columns in PostgreSQL

    - by Summer
    I sometimes re-order the columns in my Postgres DB. Since Postgres can only add columns at the end of tables, I end up re-ordering by adding new columns at the end of the table, setting them equal to existing columns, and then dropping the original columns. My question is: what does PostgreSQL do with the memory that's freed by dropped columns? Does it automatically re-use the memory, so a single record consumes the same amount of space as it did beforehand? But that would require a re-write of the whole table, so to avoid that, does it just keep a bunch of blank space around in each record? Thanks! ~S

  • Error handling and polymorphism

    - by Neeraj
    I have an application with some bunch of code like this: errCode = callMainSystem(); switch (errCode){ case FailErr: error("Err corresponding to val1\n"); case IgnoreErr: error("Err corresponding to val2\n"); ... ... default: error("Unknown error\n"); } The values are enum constants. Will it make some sense to have something like: // Error* callMainSystem() ... Some code return FaileErr(); // or some other error // handling code Error* err = callMainSystem(); err->toString(); The Error class may be made singleton as it only has to print error messages. What are the pros and cons of above methods,size is an important criteria as the application needs to be supported on embedded devices as well. P.S: I don't want to use exception handling because of portability issues and associated overheads.

  • JQuery Validation Plugin not working when used on page that includes another page via AJAX

    - by droidy
    We have a long page that contains a bunch of different form elements. One part of the form is called remotely via AJAX and is populated in an empty div. This is the part which JQuery Validation plugin is not working correctly on. We have class="required" on the elements on this page, but they do not show up as required. I'm guessing it's because the Validation plugin is looking for class="required" on our main page, and since the content from the AJAX page is put into the empty div behind the scenes, it's not detected the required fields. Any help is greatly appreciated.

  • How do I set up for sharing code (ASP.NET) across multiple domain names?

    - by Scott J.
    I have built a website and now the customer wants to split it between three different domains. What is the best way to do this? This is what I have so far. c:/website1/ points to www.website1.com c:/website1/vd1/ points to www.website2.com c:/website1/vd2/ points to www.website3.com The webhost I'm working with has done it the following way, but now I'm getting a bunch of errors that seems like it's not seeing the App_code folder. Do I need to make a lot of changes? How does this affect the location references?

  • Is there a better way to deal with reserved characters when parsing XML/JSON data on the iPhone?

    - by Charles S.
    The following code works, but it's ugly and creates a bunch of autoreleased objects. I'm using similar code for parsing reserved HTML characters as well (for quotes, & symbols, etc). I'm just wondering... Is there a cleaner way? NSString *result = [[NSString alloc] initWithString:userInput]; NSString *result2 = [result stringByReplacingOccurrencesOfString:@"#" withString:@"\%23"]; NSString *result3 = [result2 stringByReplacingOccurrencesOfString:@" " withString:@"\%20"]; formatted = [[result3 stringByReplacingOccurrencesOfString:@"&" withString:@"\%26"] retain]; [result release];

  • Rename files to increment filenumber using PowerShell?

    - by Frode Lillerud
    Hi, I've got a bunch of files named attachment.023940 attachment.024039 attachment.024041 attachment.024103 etc... I need to rename the files by incrementing the filenumber by a given number. (So that they match the right ID in a database) I guess I could write a C# application that uses RegEx to parse the filename, but I assume this is a task that could be accomplished in PowerShell as well? I've found several other threads on SO about using PowerShell to rename files, but none of them handled incrementing a filenumber. I'm on Win7, so PowerShell 2.0 is available.

  • Errors/Warnings/Debug Info no longer appears in Debug Console

    - by Alex L
    Hi Guys: This one is driving me crazy. When I run my App and open the Debug Console there is nothing there! Nope, not even the output from my NSLog statements. Before I would see a bunch of debug information starting with [Session Started ...] and ending with 'Terminating in response to SpringBoard's termination'. The Status Bar at the bottom of the Console says my App was successfully launched. Even Errors and Warnings from my code no longer appear. How do I get this to show up again? Any help would be greatly appreciated.

  • XCode enum woes

    - by Raconteur
    Hi gang, I thought I had this sorted, but I am still missing something. Very simply, I have a Settings class that hold a DAO (sitting on a plist). I want to have a couple of enums for the settings for convenience and readability, such as GamePlayType and DifficultyLevel. Right now I am defining them in the Settings.h file above the @interface line as such: typedef enum { EASY, NORMAL, HARD } DifficultyLevel; and typedef enum { SET_NUMBER_OF_MOVES, TO_COMPLETION } GamePlayType; If I access them from within the Settings class like: - (int)gridSizeForLOD { switch ([self difficultyLevel]) { case EASY: return GRID_SIZE_EASY; case NORMAL: return GRID_SIZE_NORMAL; case HARD: return GRID_SIZE_HARD; default: return GRID_SIZE_NORMAL; } } everything is fine. But, if I try to access them outside of the Settings class, let's say in my main view controller class, like this: if (([settings gameType] == SET_NUMBER_OF_MOVES) && (numMoves == [settings numMovesForLOD])) { [self showLoseScreen]; } I get errors (like EXC_BAD_ACCESS) or the condition always fails. Am I doing something incorrectly? Also, I should point out that I have this code for the call to gameType (which lives in the Settings class): - (GamePlayType)gameType { return [dao gameType]; } and the DAO implements gameType like this: - (int)gameType { return (settingsContent != nil) ? [[settingsContent objectForKey:@"Game Type"] intValue] : 0; } I know I have the DAO returning an int instead of a GamePlayType, but A) the problem I am describing arose there when I tried to use the "proper" data type, and B) I did not think it would matter since the enum is just a bunch of named ints, right? Any help, greatly appreciated. I really want to understand this thoroughly, and something is eluding me... Cheers, Chris

  • How can one describe a rock-paper-scissors relationship between 3 items?

    - by Madara Uchiha
    Let's say I have the following structure: abstract class Hand {} class Rock extends Hand {} class Paper extends Hand {} class Scissors extends Hand {} The goal is to make a function (or a method) Hand::compareHands(Hand $hand1, Hand $hand2), which would return the winning hand in a rock-paper-scissors match. That would be very easy with a bunch of ifs, but the point is to have a more robust structure, that's relying on polymorphism rather than on procedural code. P.S. this is done in actual production code, if someone is asking. This isn't some sort of challenge or homework. (It's not really rock-paper-scissors, but you get the point).

  • Maximum executable size on the iPhone?

    - by Sirp
    Is there a maximum size of executables or executables + shared objects on the iPhone? I've been developing an app that has been crashing on startup or early in execution with SIGSYS. Removing code from the program has helped, though structuring data so the code is simply not executed does not. This could be memory corruption, of some kind, however when I compiled with -Os rather than -O2 or -O3 the size of my executable goes down from 5.15MB to 3.60MB and the application runs perfectly. I also have a bunch of libraries I use, of course. I'm wondering, is there a limit on the size of executable code on the iPhone? Or am I just 'getting lucky' and masking memory corruption when I use -Os?
