  • iPhone - AES256 Encryption Using Built In Library

    - by Robert
    Hey all, I am using http://pastie.org/966473 as a reference as all I need to do is encrypt something using AES256 encrypting. I created a class and put the implementation in the pastie on top of the implementation for my class. @implementation //pastie code @end @implementation //my class code @end In my class code I create a NSMutableData and try to call the EncryptAES method and I get a warning saying it might not respond to that. What am I doing wrong here? do I need to implement the pastie code elsewhere? Thanks for any help.

  • Archiving Database Tables using Java

    - by HonorGod
    My application demands archiving database tables between sybase and db2 and vice-a-versa and within(db2 to db2 and sybase to sybase) using java. I am trying to understand the best strategies around in terms performance, implementation, ease of use and scalability. Here is my current process - source and destination tables with the acceptable parameters (from java) are defined within xml. the application reads the source and destination configurations and execute them sequentially. destination is sometime optional when source is just deleting data from a specific table or when the source is just calling a stored procedure. dataset between source and destination is extremely large (in millions) From top of my head, it looks like I can define dependencies between multiple source and destination combination and have them execute in parallel in multiple treads. But will this improve any performance(i hope it will)? Are there any open-source frameworks for data archiving using java? Any other thoughts on the implements side will be really helpful. Thanks

  • Problems using jQuery $.ajax to pass data

    - by iboeno
    I'm using ASP.NET and attempting to call a method with a signature of [WebMethod] public static string GetInfo(string id){...} using the following javascript: var elementValue = $("#element").attr('id'); var d = "{id : " + elementValue + "}"; $.ajax({ type: "POST", url: "../WebPage.aspx/GetInfo", data: d, contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { //do this } }); And this is not working. If instead I set elementValue = 2; it works fine. If I try to hardcode in a string value for testing purposes e.g. elementValue = "nameToLookUp"; It fails. Why is this happening, and how do I resolve it? On a side not, why is type: required to be POST instead of a GET? In the end I just want to pass a string value I want to look up in a DB and retrieving some json data.

  • What is the best way to add attributes to auto-generated entities (using VS2010 and EF4)

    - by Dani
    ASP.NET MVC2 has strong support for using attributes on entities (validation, and extending Html helper class and more). If I generated my Model from the Database using VS2010 EF4 Entity Data Model (edmx and it's cs class), And I want to add attributes on some of the entities. what would be the best practice ? how should I cope with updating the model (adding more fields / tables to the database and merging them into the edmx) - will it keep my attributes or generate a new cs file erasing everything ? (Manual changes to this file may cause unexpected behavior in your application.) (Manual changes to this file will be overwritten if the code is regenerated.)

  • POST serialized JSON object to a Coldfusion remote method instead of using FORM

    - by zarko.susnjar
    I have javascript object which consists of complex array of structures with nested structures of other javascript objects created dynamicaly on page etc. long story. I can't use form since my vars would be like 2_34_x_y_foo_bar_235423 due to the nature of UI. When I send that stringified object using GET .ajax request to a remote cfc method everything runs ok until JSON becomes 4000+ chars long, and usually it will be longer then that. When I use POST .ajax, I get 302 status and redirection to cfcexplorer. Is there some way I could "attach" object to a form and send my data as form submit, or some way to send JSON object as it is now using ajax call?

  • Oracle, slow performance when using sub select

    - by Wyass
    I have a view that is very slow if you fetch all rows. But if I select a subset (providing an ID in the where clause) the performance is very good. I cannot hardcode the ID so I create a sub select to get the ID from another table. The sub select only returns one ID. Now the performance is very slow and it seems like Oracle is evaluating the whole view before using the where clause. Can I somehow help Oracle so SQL 2 and 3 have the same performance? I’m using Oracle 10g 1 slow select * from ci.my_slow_view 2 fast select * from ci.my_slow_view where id = 1; 3 slow select * from ci.my_slow_view where id in (select id from active_ids)

  • Problems inserting file data into sqlite database using python

    - by tylerc230
    I'm trying to open an image file in python and add that data to an sqlite table. I created the table using: "CREATE TABLE "images" ("id" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL , "description" VARCHAR, "image" BLOB );" I am trying to add the image to the db using: imageFile = open(imageName, 'rb') b = sqlite3.Binary(imageFile.read()) targetCursor.execute("INSERT INTO images (image) values(?)", (b,)) targetCursor.execute("SELECT id from images") for id in targetCursor: imageid= id[0] targetCursor.execute("INSERT INTO %s (questionID,imageID) values(?,?)" % table, (questionId, imageid)) When I print the value of 'b' it looks like binary data but when I call: 'select image from images where id = 1' I get '????' printed to the console. Anyone know what I'm doing wrong?

  • Upload image using CURL + PHP via remote form

    - by user253530
    I have a few images that i need to upload using an online form. So far here's my code $info = array('test title','1234','virginia','@'.realpath('e:\wamp\www\1.jpg'),'@'.realpath('e:\wamp\www\2.jpg'),'@'.realpath('e:\wamp\www\3.jpg'),'@'.realpath('e:\wamp\www\4.jpg'),'test description'); $post->postAd($url, $info); The $info array is processed in the postAd method and it's being sent as an associative array using a method from a Curl class i have (it has been tested and worked nicely with everything i needed to do so far with curl). The problem is that the data is completed correctly on the form but the images are not uploaded. Can anyone help with advices/code/guidance?

  • How does one force construction of a global object in a statically linked library? [MSVC9]

    - by Peter C O Johansson
    I have a global list of function pointers. This list should be populated at startup. Order is not important and there are no dependencies that would complicate static initialization. To facilitate this, I've written a class that adds a single entry to this list in its constructor, and scatter global instances of this class via a macro where necessary. One of the primary goals of this approach is to remove the need for explicitly referencing every instance of this class externally, instead allowing each file that needs to register something in the list to do it independently. Nice and clean. However, when placing these objects in a static library, the linker discards (or rather never links in) these units because no code in them is explicitly referenced. Explicitly referencing symbols in the compilation units would be counterproductive, directly contradicting one of the main goals of the approach. For the same reason, /INCLUDE is not an acceptable option, and /OPT:NOREF is not actually related to this problem. Metrowerks has a __declspec directive for it, GCC has -force_load, but I cannot find any equivalent for MSVC.

  • Opening all external links in Phongap's ChildBrowser using jQuery Mobile

    - by Adam
    I'm using jQuery Mobile & Phonegap, and have the following code to open all external links in a certain div with the ChildBrowser: $('.someDIV a').live('click', function() { var thisUrl = $(this).attr('href'); PhoneGap.exec("ChildBrowserCommand.showWebPage", thisUrl); return false; }); For some reason, while the page loads in the childbrowser, it also loads in the background, as if there's no "return false". I've found a workaround by giving the link's href attribute a value of "#", and using the title for the url like this: And updating the jQuery code accordingly, but this is a problem where my links are dynamically generated, and I can't have the url in the title attribute. Any ideas how to solve this?

  • Inheriting from multiple classes in Java (and possibly not using interface)

    - by sheidaei
    So, let's say we have classes A, B and C and I want to inherit from all those classes and have another class called D, it can be done using implements and interfaces in Java. But let's say we don't want to use this simple solution, would you be able to inherit class D from classes A, B and C in any other way in Java? (This question might be related to design patterns, it has been brought up after challenging my colleague at lunch discussing design patterns) I don't think there is any other way to have multiple inheritance in Java other than using multiple interfaces.

  • Accessing a variable passed by jquery using php

    - by celenius
    How does php access a variable passed by JQuery? I have the following code: $.post("getLatLong.php", { latitude: 500000}, function(data){ alert("Data Loaded: " + data); }); but I don't understand how to access this value using php. I've tried $userLat=$_GET["latitude"]; and $userLat=$_GET[latitude]; and then I try to print out the value (to check that it worked) using: echo $userLat; but it does not return anything. I can't figure out how to access what is being passed to it.

  • How to implement HeightMap smoothing using Thrust

    - by igal k
    I'm trying to implement height map smoothing using Thrust. Let's say I have a big array ( around 1 million floats). A known graphics algorithm to implement the above problem is to calculate the average around a given cell. If for example I need to calculate the value at a given cell[i,j] what I will basically do is: cell[i,j] = cell[i-1,j-1] + cell[i-1,j] + cell[i-1,j+1] + cell[i,j-1] + cell[i,j+1] + cell[i+1,j -1] + cell[i+1,j] + cell[i+1,j+1] cell[i,j] /=9 That's the CPU code. Is there a way to implement it using thrust? I know that I could use the transform algorithm. But I'm not sure it's correct to access different cells which are occupied but different threads (banks conflicts and so on).

  • CodeIgniter Question: How to delete records using ActiveRecord with mySQL function as WHERE conditio

    - by Jhourlad Estrella
    I have a table named ChatSessions where I keep track of active users in the chatroom. I need to prune expired user sessions from the table every 10 minutes. Using pure php-mysql is plain simple but I'm totally clueless how to convert this into ActiveRecord in CodeIgniter. The plain SQL query is below: SELECT * FROM `ChatSessions` WHERE `SessionExpires` < DATE_SUB( NOW( ) , INTERVAL 10 MINUTE ) Can anybody tell me what is the equivalent code in CodeIgniter using ActiveRecord? Thanks in advanced.

  • Problem with input filter using doxygen 1.6.3 on windows XP

    - by Marc
    I am trying to use doxygen to generate documentation for some matlab classes I have written. I am using the doxygen-matlab package, which includes a perl script to kludge matlab .m files into c++ style commented files, so that doxygen can read them. In my doxyfile, I have set (according to the instructions) FILTER_PATTERNS = *m=C:/doxygenMatlab/m2cpp.pl However, when the code runs, rather than running the script on the input files, it appears to just open the script using whatever the default windows setting for .pl is. IE, if I associate .pl with notepad, the script is opened by notepad once for each input file doxygen is trying to parse. If I associate .pl with perl.exe, the script runs and throws the no argument error Argument must contain filename -1 at C:\doxygenMatlab\m2cpp.pl line 4. The doxygen documentation says Doxygen will invoke the filter program by executing (via popen()) the command <filter> <input-file> So I am wondering if there is some problem with popen() and windows that I could fix.

  • What environment variables available while starting the script using init.d boot process

    - by raj_arni
    My problem is like this (OS is Sun Solaris): 1) At the boot time I want to start a process using a specific script. I am doing this by putting this script in /etc/init.d (and following other K and S rules) 2) The program which will be called by the script is located at $HOME/xxx/yyy location. 4) I am using 'su - {myuser} -c "{full path of the program}"' in order to execute the script as {myuser} 3) I dont want to hardcode the value of $HOME in the script but want to use the $HOME env variable only. How can I get this $HOME env variable in the shell script? Also what other variables will be available to me?

  • How to get the records using order by and so on

    - by paulrajj
    I have a table categories containing categories id having the records of 1 to 20. when i am doing the search query by using the IN function in mysql i got the results. but i am struggling to get the results using order by. The limit may be vary for every search as this is one of the input value. For example I have tried this query to find out the search results, select * from categories where category in (20,16,12,8) order by rand(), id limit 0,6 this query is executed and the results are in random category_id. the results will be, 8 12 16 20 and following this, another two records must be 8 12 If category_id contains only one record for 8 then, it should follow from 12,16. How can i achieve this ? thanks in advance.
