  • Extract form variable in AJAX response using jquery

    - by Jake
    All, I have a Jquery ajax request calling out a URL. The ajax response I receive is an HTML form with one hidden variable in it. As soon as my ajax request is successful, I would like to retrieve the value of the hidden variabl. How do I do that? Example: html_response for the AJAX call is : <html><head></head><body><form name="frmValues"><input type="hidden" name="priceValue" value="100"></form></body></html> $.ajax({ type: 'GET', url: "/abc/xyz/getName?id="+101, cache: false, dataType: "html", success: function(html_response) { //Extract form variable "priceValue" from html_response //Alert the variable data. } }); Thanks

  • TeX on iPad compatible with Apple's policy?

    - by Yuji
    Hi, As a nerd, I think it would be nice to have a TeX editor on the iPad. But TeX is a Turing-complete language, and it is arguably a general-purpose compiler/interpreter. Does that make it unacceptable to the App Store? Furthermore, if somebody ports TeX compiler to javascript and runs inside WebKit, does it make acceptable to the App Store? FYI, here's the section of the developer's agreement: 3.3.2 An Application may not itself install or launch other executable code by any means, including without limitation through the use of a plug-in architecture, calling other frameworks, other APIs or otherwise. No interpreted code may be downloaded and used in an Application except for code that is interpreted and run by Apple's Published APIs and builtin interpreter(s).

  • Ignore certificate errors when requesting a URL in Java

    - by Ryan Elkins
    I'm trying to print a URL (without having a browser involved at all) but the URL is currently throwing the following: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target I'm calling the URL using a JEditorPane's setPage method, which just takes a URL as a parameter. Assuming I can't change anything server side and I still need to get to this resource, how would I go about ignoring the certificate error (or something else that gets me to my goal)? Accessing this URL via a browser tells me the site is untrusted and asks me if I want to proceed.

  • C# ASP.Net The type or namespace name 'Secure' does not exist in the namespace 'source_extranet'

    - by Louis Russell
    Afternoon all, I really need your help as this is a Nightmare! I was earlier having a problem with referencing a 3rd Party Dll (Here) but have overcome this problem and am now having a problem referencing my own classes! Everything seems fine at build with no errors at all but when I go to run the application it comes up with the following Compilation Error: Compiler Error Message: CS0234: The type or namespace name 'Secure' does not exist in the namespace 'source_extranet' (are you missing an assembly reference?) The line that the Error points to this line in the class: source_extranet.Secure.BackendCustomData newdata = new source_extranet.Secure.BackendCustomData(); This line of code points to a class in the same folder as the calling code class. I have scoured Google looking for an answer and haven't found anything that points me to an answer to my problem. Any help would be AMAZING!

  • Protecting Data Feed for iPhone App

    - by Chris
    I am creating an App that pulls data from a file on my server. That file gets data from my database, based on GET values that are passed through the URL. I would like to keep this feed closed - that is, I don't want people finding the datasource and reading the data on their own. I considered sending an alphanumeric id along with the url string, but if they can find the URL that I am calling, then there won't be anything preventing them from grabbing that alphanumeric id also. I am looking for any ideas or experiences that might help me here. Thanks.

  • WPF: isolated storage file path too long

    - by user342961
    Hi, I'm deploying my WPF app with ClickOnce. When developing locally in Visual Studio, I store files in the isolated storage by calling IsolatedStorageFile.GetUserStoreForDomain(). This works just fine and the generated path is C:\Users\Frederik\AppData\Local\IsolatedStorage\phqduaro.crw\hux3pljr.cnx\StrongName.kkulk3wafjkvclxpwvxmpvslqqwckuh0\Publisher.ui0lr4tpq53mz2v2c0uqx21xze0w22gq\Files\FilerefData\-581750116 (189 chars) But when I deploy my app with ClickOnce, the generated path becomes too long, resulting in a DirectoryNotFoundException when creating the isolated storage directory. The generated path with ClickOnce is: C:\Users\Frederik\AppData\Local\Apps\2.0\Data\OQ0LNXJT.R5V\8539ABHC.ODN\exqu..tion_e07264ceafd7486e_0001.0000_b8f01b38216164a0\Data\StrongName.wy0cojdd3mpvq45404l3gxdklugoanvi\Publisher.ui0lr4tpq53mz2v2c0uqx21xze0w22gq\Files\FilerefData\-581750116 (247 chars) When I browse the folders all but the last directory of the path exists. Then when trying to create a folder at this location windows tells me I can't create a directory because the resulting path name will be too long. How can I shorten the path generated by the IsolatedStorage?

  • Prevent password leakage while using sql* loader

    - by Jai
    I have shell script calling Sql*loader utility which inturn uses username/password as arguments. This details cannot be stored on server in any form due to security related policies. i got 2 approaches to handle this situation, 1. create hidden parameter file with login details and limit the access to owner. again the implication is i cannot store login data in any format on server 2. Create the user as OS authenticated and straight away login into sql without any userid/password I am not able to figure out risks involved in 2nd approach which u experienced folks could have come across. let me know if there is any other approach to handle password leakage issue

  • Using Ruby Hash instead of Rails ActiveRecord in Coffeescript / Morris.JS

    - by Vanessa L'olzorz
    I'm following the Railscast #223 that introduced Morris.JS. I generate a data set called @orders_yearly in my controller and in my view I have the following to try and render the graph: <%= content_tag :div, "", id: "orders_chart", data: {orders: @orders_yearly} %> Calling @orders_yearly.inspect shows it's just a simple hash: {2009=>1000, 2010=>2000, 2011=>4000, 2012=>100000} I'll need to modify the values for xkey and ykeys in coffeescript to work, but I'm not sure how to make it work with my data set: jQuery -> Morris.Line element: 'orders_chart' data: $('#orders_chart').data('orders') xkey: 'purchased_at' # <------------------ replace with what? ykeys: ['price'] # <---------------------- replace with what? labels: ['Price'] Anyone have any ideas? Thanks!

  • How do I get Linq-to-SQL to refresh its local copy of a database record?

    - by Gary McGill
    Suppose I have an Orders table in my database and a corresponding model class generated by the VS2008 "Linq to SQL Classes" designer. Suppose I also have a stored procedure (ProcessOrder) in my database that I use to do some processing on an order record. If I do the following: var order = dataContext.Orders.Where(o => o.id == orderId).First(); // More code here dataContext.ProcessOrder(orderId); order.Status = "PROCESSED"; dataContext.SubmitChanges(); ...then I'll get a concurrency violation if the ProcessOrder stored proc has modified the order (which is of course very likely), because L2S will detect that the order record has changed, and will fail to submit the changes to that order. That's all fairly logical, but what if I want to update the order record after calling the stored proc? How do I tell L2S to forget about its cached copy and refresh it from the DB?

  • Advice on coding Perl to work like PHP

    - by user272273
    I am first and foremost a perl coder, but like many, also code in PHP for client work, especially web apps. I am finding that I am duplicating a lot of my projects in the two languages, but using different paradigms (e.g. for handling cgi input and session data) or functions. What I would like to do is start to code my Perl in a way which is structured more like PHP, so that I a) am keeping one paradigm in my head b) can more quickly port over scripts from one to the other Specifically, I am asking if people could advise how you might do the following in perl? 1) Reproduce the functionality of $_SESSION, $_GET etc. e.g. by wrapping up the param() method of CGI.pm, a session library? 2) Templating library that is similar to PHP I am used to mixing my code and HTML in the PHP convention. e.g. i <h1>HTML Code here</h1> <? print "Hello World\b"; ?> Can anybody advise on which perl templating engine (and possibly configuration) will allow me to code similarly? 3) PHP function library Anybody know of a library for perl which reproduces a lot of the php inbuilt functions?

  • Trouble with javascript subtraction

    - by rockinthesixstring
    I'm working on a simple subtraction problem, but unfortunately it keeps returning NaN Here is the function function subtraction(a, b) { var regexp = /[$][,]/g; a = a.replace(regexp, ""); b - b.replace(regexp, ""); var _a = parseFloat(a); var _b = parseFloat(b); return _a - _b; } And here is how I'm calling it. txtGoodWill.value = subtraction(txtSellingPrice.value, txtBalanceSheet.value); The numbers that get submitted to the function are ONLY Currency (IE: $2,000 or $20, etc) Now I know that I cannot subtract numbers with a $ or a ,, but I can't for the life of me figure out why they are getting evaluated in the equasion.

  • How can I retain carriage returns when I'm encrypting data?

    - by William Calleja
    I have this following setup, a textarea named with some data in it that may have carriage returns and another textarea that has style='display:none' in order to make it hidden as follows: <textarea id="myTextarea" onBlur="encryptMyData()"></textarea> <textarea name="encryptedText" style='display:none'></textarea> the user enters data in the first textarea and when that text area loses focus the 'encryptMyData()' javascript function is calling an ajax call to take whatever the user entered in the first textfield, encrypt it using rijndael, and paste it in the encryptedText textarea so that it is stored in the database later. Now what I need to do is this, find a way to convert the carriage returns before encryption to a tag like so [cr] so that when I retrieve the data, all formatting is retained. Any idea how I do this? I'm using asp.net and c# to perform the encryption.

  • Problems with VBScript - RegRead when running as a service

    - by Brandon
    I am working on a script that runs under a custom installation utility, which is running as a service. To get the current user name the script executes this command: str_Acct_Name_Val = "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Logon User Name" str_Acct_Name = RegRead(str_Acct_Name_Val) When I run the script from the command prompt, it can read that value just fine (under an administrator account). When the value is attempted to be read with service/local system privileges, the read fails. What is the problem here? EDIT: Some additional information. When running as a service calling the current user name returns "SYSTEM" and my guess is that HKCU doesn't "exist" under the view of the SYSTEM, since there is technically no current user. There is a user logged in at the time, but not in the scope of the running script. Maybe there is somewhere in HKLM I could find the currently logged on user?

  • How to use ORDER BY, LOWER .. in SQL SERVER 2008 with non-unicode data

    - by hgulyan
    Hi, The question is about Armenian. I'm using sql server 2005, collation SQL_Latin1_General_CP1_CI_AS, data mostly is in Armenian and we can't use unicode. I tested on ms sql 2008 with a windows collation for armenian language ( Cyrillic_General_100_ ), I have found here, ( http://msdn.microsoft.com/en-us/library/ms188046.aspx ) but it didn't help. I have a function, that orders hex values and a lower function, which takes each char in each string and converts it to it's lower form, but it's not acceptable solution, it works really slow, calling that functions on every column of a huge table. Is there any solution for this issue not using unicode and not working with hex values manually?

  • Is an object in objective-c EVER created without going through alloc?

    - by Jared P
    Hi, I know that there are functions in the objective-c runtime that allow you to create objects directly, such as class_createInstance. What I would like to know is if anything actually uses these functions other than the root classes' (NSObject) alloc method. I think things like KVC bindings might, but those aren't present on the iPhone OS (to my knowledge, correct me if I'm wrong), so is there anything that would do this? In case you're wondering/it matters, I'm looking to allocate the size of an instance in a way that circumvents the objc runtime by declaring no ivars on a class, but overriding the +alloc method and calling class_createInstance(self, numberofbytesofmyivars). Thanks

  • jquery: why a selector returns me an array, but attribute doesnt?

    - by Shlomi.A.
    Hi. I'm trying to understand JQ better. I'm calling an JQ object $(".FamiliesList li li span[class!='']").prev().find('option:selected') this returns back to me an array of all the options that their span parent's brother has a classname. [option, option] Now- I want to return back an array of the option's values $(".FamiliesList li li span[class!='']").prev().find('option:selected').attr('value') this returns back to me only the first child value, and a full array of the values. Why? I would appreciate to receive help and understand jq better :) Thanks.

  • Audio -- How much performance improvement can I expect from from reducing function calls by using bu

    - by morgancodes
    I'm working on an audio-intensive app for the iPhone. I'm currently calling a number of different functions for each sample I need to calculate. For example, I have an envelope class. When I calculate a sample, I do something like: sampleValue = oscilator->tic() * envelope->tic(); But I could also do something like: for(int i = 0; i < bufferLength; i++){ buffer[i] = oscilatorBuffer[i] * evelopeBuffer[i]; } I know the second will be more efficient, but don't know by how much. Are function calls expensive enough that I'd be crazy not to use buffers if I care event a tiny bit about performance?

  • Is there any way to get MSVC to pass structs arguments in registers on x64?

    - by Luke
    For a function with signature: struct Pair { void *v1, *v2 }; void f(Pair p); compiled on x64, I would like Pair's fields to be passed via register, as if the function was: void f(void *v1, void *v2); Compiling a test with gcc 4.2.1 for x86_64 on OSX 10.6, I can see this is exactly what happens by examining the disassembly. However, compiling with MSVC 2008 for x64 on Windows, the disassembly shows that Pair is passed on the stack. I understand that platform ABIs can prevent this optimization; does anyone know any MSVC-specific annotations, calling conventions, flags, or other hacks that can get this to work? Thank you!

  • GC.AddMemoryPressure in C#

    - by ssheldon
    I am writing an application in C# that makes use of a 3rd party COM DLL, this dll creates a lot of resources (like bitmaps, video, data structures) in unmanaged memory. While digging around I came across the following call for the Garbage Collector: GC.AddMemoryPressure(long long bytesAllocated) It is documented in MSDN here: http://msdn.microsoft.com/en-us/library/system.gc.addmemorypressure.aspx This sounds like something I should be calling since this external dll is createing a lot of resources the CLR is unaware of. I guess I have two questions... How do I know how much memory pressure to add when the dll is 3rd party and it's not possible for me to know exactly how much memory this dll is allocating. How important is it to do this?

  • How do laziness and I/O work together in Haskell?

    - by Bill
    I'm trying to get a deeper understanding of laziness in Haskell. I was imagining the following snippet today: data Image = Image { name :: String, pixels :: String } image :: String -> IO Image image path = Image path <$> readFile path The appeal here is that I could simply create an Image instance and pass it around; if I need the image data it would be read lazily - if not, the time and memory cost of reading the file would be avoided: main = do image <- image "file" putStrLn $ length $ pixels image But is that how it actually works? How is laziness compatible with IO? Will readFile be called regardless of whether I access pixels image or will the runtime leave that thunk unevaluated if I never refer to it? If the image is indeed read lazily, then isn't it possible I/O actions could occur out of order? For example, what if immediately after calling image I delete the file? Now the putStrLn call will find nothing when it tries to read.

  • Accessing the Custom Object Return type from ojdbc6 JDBC Thin Drivers

    - by Andrew Harmel-Law
    I'm writing some JDBC code which calls a Oracle 11g PL/SQL procdedure which has a Custom Object return type. I can get the code to call the procedure, but how do I access the returned Custom Object to obtain it's contained values?. An example of my code calling the procedure is below: PLSQL Code: Procedure GetDataSummary (p_my_key IN KEYS.MY_KEY%TYPE, p_recordset OUT data_summary_tab, p_status OUT VARCHAR2); Java Code: String query = "begin manageroleviewdata.getdatasummary(?, ?, ?); end;"); CallableStatement stmt = conn.prepareCall(query); stmt.setInt(1, 83); stmt.registerOutParameter(2, OracleTypes.ARRAY, "DATA_SUMMARY_TAB"); stmt.registerOutParameter(3, OracleTypes.VARCHAR); stmt.execute(stmt); How do I get the result back fron this?

  • Partial match in MaskFormatter for jFormattedTextField

    - by Toto
    How do I set up the MaskFormatter and the JFormattedTextField in order to allow partial matches? For example: I want the user to be able to enter numbers with this mask "## ###### ####", so if the user enters '123456789123' the formatter changes it to '12 345678 9123'. However, I also want the user to be able to enter '12346578', be converted to '12 345678' and still be a valid value (so I can get it using jFormatedTextField1.getValue()) This is part of my code (most of it generated by Netbeans): private javax.swing.JFormattedTextField jFormattedTextField1; // ... try { jFormattedTextField1.setFormatterFactory(new DefaultFormatterFactory(new MaskFormatter("## ###### ####"))); } catch (java.text.ParseException ex) { ex.printStackTrace(); } I've tried setting the focusLostBehavior to PERSIST so the value is not cleard after exiting the jFormattedTextField1, but that way I get a null when using the calling jFormattedTextField1.getValue()

  • Strange problem with SEAM stateful session bean

    Hi, I've got a staeful session bean. @Scope(ScopeType.SESSION) @Name("chuckNorrisBean") public class ChuckNorrisBean implements Serializable, ChuckNorris with some function public void roundHouseKick() { ... } interface @Local public interface ChuckNorris { public void roundHouseKick() { ... } } and calling them on a jsf .xhtml page using #{chuckNorrisBean.roundHouseKick} which works perfectly fine. However if I add the @Stateful annotation to the bean so it becomes @Stateful @Scope(ScopeType.SESSION) @Name("chuckNorrisBean") public class ChuckNorrisBean implements Serializable, ChuckNorris and the page will load with exceptions complainig about Exception during request processing:Caused by javax.servlet.ServletException with message: "#{chuckNorrisBean.roundHouseKick}: javax.el.MethodNotFoundException: //localhost/universe/earth.xhtml @41,65 action= "#{chuckNorrisBean.roundHouseKick}": Method not found: ChuckNorrisBean:a6gkg-w6das4-g8wmgh0y-1-g8woy0wo-4b.roundHouseKick()" Any advice on what might've went wrong with my chuckNorrisBean?

  • Auto scrolling or shifting a bitmap in .NET

    - by mikej
    I have a .NET GDI+ bitmap object (or if it makes the problem easier a WPF bitmap object) and what I want to to is shift the whole lot by dx,dy (whole pixels) and I would ideally like to do it using .NET but API calls are ok. It has to be efficient bacause its going to be called 10,000 times say with moderately large bitmaps. I have implemented a solution using DrawImage - but its slow and it halts the application for minutes while the GC cleans up the temp objects that have been used. I have also started to work on a version using ScrollDC but so far have had no luck getting it to work on the DC of the bitmap (I can make it work buy creating an API bitmap with bitmap handle, then creating a compatible DC asnd calling ScrollDC but then I have to put it back into the bitmap object). There has to be an "inplace" way of shifting a bitmap. mikej

  • How to declare more than one header on PHP

    - by Homer Simpson
    I want to send my users to different pages based on user action. So I made multiple functions at the top of the page like so: <?php function one() { header("location: pagea.php"); } function two() { header("location: pageb.php"); } function three() { header("location: pagec.php"); } ?> Of course I get an error because I am re declaring headers. At first I though it was going to be okay since I am containing them inside functions and am calling any one function at a time. But still I get the error. Is there any other way of doing this?
