  • 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.

  • MSBuild - setting a reference path

    - by Ryan
    I have several assemblies my project is dependant upon. These are stored in the Project's directory under the "Dependencies" folder. So something like this. Solution - Project - Dependancies FunkyAssembly.dll - bin - Debug - Release SomeCode.cs I've referenced FunkyAssembly.dll using Browse and in project.csproj I see <Reference Include="FunkyAssembly"> <HintPath>Dependancies\FunkyAssembly.dll</HintPath> </Reference> So far so good - except after a release build FunkyAssembly.dll is copied to the Release directory (not a problem in itself) but then future debug builds will reference this copy rather than the copy in Dependencies. You can see this if you at Path in the reference properties. This means that if Dependencies\FunkyAssembly.dll is updated the build won't pick it up as its referencing the old copy in bin/Release. Any way to FORCE the damn thing to pick up Dependencies\FunkyAssembly.dll rather than HINT?

  • Is it naughty to have a large utility file?

    - by banister
    In my C project I have quite a large utils.c file. It is really full of many utilities of different sorts. I feel a bit naughty just stuffing different miscellaneous functions in there. For example it has some utilities related to low level stuff such as a lowercase() function, and it also has some quite sophisticated utilities such as converting to/from different colour formats. My question is, is it very naughty to have such a large utils.c with many different types of utilities in it? Should I break it up into many different kinds of utility files? Such as graphics_utils.c and so on What do you think?

  • How would you audit ASP.NET Membership tables, while recording what user made the changes?

    - by Pete
    Using a trigger-based approach to audit logging, I am recording the history of changes made to tables in the database. The approach I'm using (with a static sql server login) to record which user made the change involves running a stored procedure at the outset of each database connection. The triggers use this username when recording the audit rows. (The triggers are provided by the product OmniAudit.) However, the ASP.NET Membership tables are accessed primarily through the Membership API. I need to pass in the current user's identity when the Membership API opens its database connection. I tried subclassing MembershipProvider but I cannot access the underlying database connection. It seems like this would be a common problem. Does anyone know of any hooks we can access when the ASP.NET Membership makes its database connection?

  • 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

  • Compiling zip component for PHP 5.2.11 in MAMP PRO

    - by Zlatoroh
    Helo I installed MAMP PRO on my Macbook Pro (10.6) some time ago. Now I would like to use zip functions in php. I found that I must add zip.so to my extension folder and edited php.ini. On my computer I have two different versions of PHP one in MAMP folder and other in user/lib which was pre-installed on my system. Now I wish to compile my zip library for MAMP version. I got zip sources for my version of PHP then in terminal called function /Applications/MAMP/bin/php5/bin/phpize so it uses mamp php version ./configure make then I moved compile zip.so to extensions/no-debug-non-zts-20060613. When MAMP is launched it returns this error: [11-Apr-2010 16:33:27] PHP Warning: PHP Startup: zip: Unable to initialize module Module compiled with module API=20090626, debug=0, thread-safety=0 PHP compiled with module API=20060613, debug=0, thread-safety=0 These options need to match in Unknown on line 0 Can some body explain to me how to do this the right way.

  • Cannot login to drupal in Chrome or Firefox, but Safari works

    - by WmasterJ
    Problem: Login is not working in Firefox and Chrome but it does in Safari. Details: We just moved a drupal 6 installation to another host and followed some steps: Moved sites/site1/Themes/themeFolder to sites/all/Themes/themeFolder Made these changes in page-node-NNN.tpl.php files (searched all files in themes/themeFolder): 1) find: /oldpath/ replace: /newpath/ 2) find: oldsubdomain. replace: www. 3) find: .com/sites/ replace: .com/newpath/sites/ Then as I login it fails in any browser when the wrong information is entered but when it is correct it simply redirects to that users profile page...and then nothing. There are no admin menus, no edit buttons for content and it is a though it authenticated but somehow never stored anything that would help with the authentication later. The strange thing is that for 3 people with three different systems Firefox and Chrome don't work. But Safari does. We have ruled out that it is the database or old cookies. Any one have a good guess?

  • How does jQuery stores data with .data()?

    - by TK
    I am a little confused how jQuery stores data with .data() functions. Is this something called expando? Or is this using HTML5 Web Storage although I think this is very unlikely? The documentation says: The .data() method allows us to attach data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks. As I read about expando, it seems to have a rick of memory leak. Unfortunately my skills are not enough to read and understand jQuery code itself, but I want to know how jQuery stores such data by using data(). http://api.jquery.com/data/

For example, when I input (5+6i)(6+1i), it just gives (5+6i)(6+1i). Even if I input any other things, for example, input "abc" it just gives "abc" and is not syntax error. I don't know where the problem is and I hope to know how to solve it.

  • onbeforeunload in safari does not run code server side

    - by Deepa
    On browser close or F5, I have to perform some code on server side For this I have a button. On click of that button which has onclientclick and onclick functions written. I also wrote an event on window.onbeforeunload which does a button.click(). window.onbeforeunload=function(e) { button.click() } My problem is that this runs the code of the client side click function of the button, however server side code does not get executed. This happens only when i close the browser. When I do F5 it works perfectly. Also this happens only on Safari. In FF and mozila it works perfectly . How can i

  • get the expanding node in a treeview

    - by Iulian
    I have a treeview control that functions like a folder browser. Because loading the entire folder structer from disk is taking a lot of time i'm trying to load only one level at a time. So i have a function that adds nodes for all the folders in the current node. I thought that the best method would be to run it on the BeforeExpand event of the treeview. UpdateTreeView(TreeView.SelectedNode); is not working because clicking the + sign to expand is not selecting the node also. So how to find the node that is expanding.

  • How to use/manipulate return value from nested boost::bind

    - by JQ
    I have two functions: 1. A & DataSource(); 2. void DataConsumer( A * ); What I want to achieve: Using one statement to assemble them into one functor. I have tried: 1. boost::function< void() func( boost::bind( DataConsumer, & boost::bind( DataSource ) ) ); certainly it didn't work, compiler says it can not convert 'boost::_bi::bind_t ' to 'A *' 2. boost::function< void() func( boost::bind( DataConsumer, boost::addressof( boost::bind( DataSource ) ) )); compiler says cannot convert parameter 1 from 'boost::_bi::bind_t' to 'A &' Question: how to use return value from the nested boost::bind ? or if you want to use boost::lambda::bind.

  • solution on SP and EF & Ria Service

    - by KentZhou
    As EF 4.0 released, more support to SQL server Stored procedure. Complex Type can be generated automatically for result dataset of SP. But complex type not support by Ria Service. When I try to use ria service combined with EF 4.0, I want to get dataset by SP. This result is not mapped to any entity/table. Some sulutions suggested by community are: 1. Create view to map sp result. (but for EF, if there is no ID or primary, can't be map to any entity) 2. Create Entity to map sp result.(for this, you even need to map SP for CRUD even though I don't need CUD on this sp result) Also above solution can't be automated. As Database objects maybe changed with the time, auto update edm will lost above solution. So what's the solution? I want to put data operation back to DB as possible, so that many changes can be done in DB and no need to rebuild .net assemblies(this cause redeploy).

  • Accessing a master page from httphandler

    - by vondip
    Hi All, I am developing a small application in asp.net (writing in c#). In my application I am using jquery to perform asynchronous call to the server. I have an http handler that listens in to the requests and does what it needs to do. Problems start when in the handler I need to access information stored in the page , from where the asynchronous call started. When I try this: Page page = HttpContext.Current.Handler as Page; I don't get a page. How else can I access the page itself? Thank you

  • slsvcutil.exe Proxy and Interfaces

    - by JPM
    Is it possible when using slsvcutil.exe to generate a proxy through the command line not to have the proxy file output the Interface in an Asynchronous fashion. For example, if I have a function "foo()" on the serverside in the Interface, when I generate the proxy using Slsvcutil.exe, it makes two functions in the interface definition in the proxy named "BeginFoo()" and "EndFoo()". All I want is "Foo()", I don't need the other two methods. Is this possible? I'm using the proxy with Monotouch which is why I need to use Slsvcutil.exe but don't need the Asynchronous methods. Thanks!

  • Sort an array by a child array's value

    - by Evan
    I have an array composed of arrays. I want to sort the parent array by a property of the child arrays. Here's an example array(2) { [0]=> array(3) { [0]=> string(6) "105945" [1]=> string(10) "First name" [2]=> float(0.080878465391) } [1]=> array(3) { [0]=> string(6) "109145" [1]=> string(11) "Second name" [2]=> float(0.0504154818384) } I would like to sort the parent array by [2] ascending in the child arrays, so in this case the result would be the child arrays reversed (.05, 08). Is this possible using any of the numerous PHP sort functions?

  • C# .net -> SQLite error: Unable to open the database file

    - by CODe
    Hello all, I'm getting "System.Data.SQLite.SQLiteException: Unable to open the database file." when I attempt to access the database to save a record upon the "first" opening of my program. Here's the thing, it works fine when debugging locally in Visual Studio, but stops working when I package the program in an installer, and then install the program somewhere. I was guessing that it was the location of the database, which I just have set at database.s3db without a path, because it is stored next to the program's exe, but how could that cause problems? I'm at a loss, any further ideas or suggestions for solving this problem would be greatly appreciated.

  • Java Memory Overhead

    - by flamealpha
    Hello, I would like to ask about Memory Overhead in java, I have a large ArrayList (61,770 items), and trying to calculate the amount of memory taken by each item (counting the object and its ArrayList entry), by profiling the app i get that after all the data is loaded, the heap takes ~ 25Mb. when the ArrayList has only 2 items the heap takes ~1Mb , so roughly: (24*1024*1024)/61,768 = 407 bytes. however, when i count the fields of the each object, i get 148 bytes(not including the ArrayList, and assuming int=4,float=4,reference=4), I am curious to know where did all of those extra bytes came from... i can guess that since the objects I store in the ArrayList are implementing an interface, they store extra values, maybe the VM stores a 4byte function pointer for each implemented method? the interface they implement have 20 functions so thats 80 more bytes, totaling 228 bytes, still not close to the 400 bytes measured. any help would be appreciated.

  • 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?

  • "Microsoft DNS Client" vs. getaddrinfo?

    - by Josh K
    Right now, my application is using the c-ares asynchronous DNS resolver library on Windows below cURL, and I have users complaining that it behaves differently from other windows apps. One particular user said that "other applications are using the Microsoft DNS client" and experiences no problems. cURL itself has an asynchronous DNS implementation that uses getaddrinfo() in a thread. My guess is that would be equivalent behavior to using the "DNS Client" and its host of functions (e.g. DnsQuery?) So, dear Lazyweb, I ask if there is a tangible difference between the behavior of getaddrinfo() vs. using the actual Dns* APIs from the Win32 API.

  • How to make a Django model fields calculated at runtime?

    - by Anatoly Rr
    I have a model: class Person (models.Model): name = models.CharField () birthday = models.DateField () age = models.IntegerField () I want to make age field to behave like a property: def get_age (self): return (datetime.datetime.now() - self.birthday).days // 365 age = property (get_age) but at the same time I need age to be a true field, so I can find it in Person._meta.fields, and assign attributes to it: age.help_text = "Age of the person", etc. Obviously I cannot just override Person.save() method to calculate and store age in the database, because it inevitably will become wrong later (in fact, it shouldn't be stored in the database at all). Actually, I don't need to have setters now, but a nice solution must have setting feature. Is it possible in Django, or probably there is a more pythonic and djangoic approach to my problem?

  • Sharing a custom datasource between Winforms and Webforms

    - by Earlz
    Hello, I'd like to create a custom datasource that is shared between a Winforms and Webforms project. This functions as a middle layer for a reporting tool(DevExpress Reporting). The Webforms project is a designer for these reports. So we want for the reports to be capable of going to the server to get data and such. So our datasource would abstract away all the communication overhead. Then, for consistency, the datasource would also run on the server for reporting, except for their would be no communication. What would be the best course of action? There doesn't seem to be such a thing as a DataSource in Winforms. Is DataSource not the thing I'm looking for? Edit: After some research, it appears that IDataAdapter may be good for my purpose. Any opinion on that?

  • ActionScript 3 class over several files - how?

    - by Poni
    So, how do we write a class over several files in action script 3? In C# there's the "partial" keyword. In C++ it's natural (you just "#include ..." all files). In Flex 3, in a component, you add this tag: <mx:Script source="myfile.as"/>. How do I split the following class into several files; package package_path { public class cSplitMeClass { public function cSplitMeClass() { } public function doX():void { // .... } public function doY():void { // .... } } } For example I want to have the doX() and doY() functions implemented in another ".as" file. Can I do this? And please, don't tell me something like "a good practice is to have them in one file" :)
