  • password/login system in php

    - by Jonathan
    For a login system in php would this be a suitable outline of how it would work: users types in username and password, clicks login button. Checks if user exists in database, if it does, then retrieve the salt for that user hash the password and salt (would this be done on the client or server side? I think client side would be better, but php is server side so how would you do this?) check value against value in database, if the values match then user has typed in correct password and they are logged in.

  • Java - Optimize finding a string in a list

    - by Mark
    I have an ArrayList of objects where each object contains a string 'word' and a date. I need to check to see if the date has passed for a list of 500 words. The ArrayList could contain up to a million words and dates. The dates I store as integers, so the problem I have is attempting to find the word I am looking for in the ArrayList. Is there a way to make this faster? In python I have a dict and mWords['foo'] is a simple lookup without looping through the whole 1 million items in the mWords array. Is there something like this in java? for (int i = 0; i < mWords.size(); i++) { if ( word == mWords.get(i).word ) { mLastFindIndex = i; return mWords.get(i); } }

    I want to find the Mode in an Array. I know that I have to do nested loops to check each value and see how often the element in the array appears. Then I have to count the number of times the second element appears. The code below doesn't work, can anyone help me please. for (int i = 0; i < x.length; i ++) { x[i]++; int high = 0; for (int i = 0; i < x.length; i++) { if (x[i] > high) high = x[i]; } }

  • Checking if a string's characters are ascending alphabetically and its ascent is evenly spaced python

    - by FRU5TR8EDD
    So need to check if a string's characters are ascending alphabetically and if that ascent is evenly spaced. a = "abc" b = "ceg" So a is alphabetically ascending and it's spacing is 1 (if you convert to the ordinal values they are 97,98,99). And b is also alphabetically ascending and it's spacing is 2 (99,101,103). And I am sticking with the following code: a = 'jubjub' words1 = [] ords = [ord(letter) for letter in a] diff = ords[1] - ords[0] for ord_val in range(1, len(ords)-1): if diff > 0: if ords[ord_val + 1] - ords[ord_val] == diff: if a not in words1: words1.append((a, diff)) print words1 How come 'jubjub' works, 'ace' works, but 'catcat' doesn't?

  • MVVM Binding To Property == Null

    - by LnDCobra
    I want to show some elements when a property is not null. What is the best way of achieving this? The following is my ViewModel: class ViewModel : ViewModelBase { public Trade Trade { get { return _trade; } set { SetField(ref _trade, value, () => Trade); } } private Trade _trade; } ViewModelBase inherits INotifyPropertyChanged and contains SetField() The Following is the Trade class: public class Trade : INotifyPropertyChaged { public virtual Company Company { get { return _company; } set { SetField(ref _company, value, () => Company); } } private Company _company; ...... } This is part of my View.xaml <GroupBox Visibility="{Binding Path=Trade.Company, Converter={StaticResource boolToVisConverter}}" /> I would like this groupbox to show only if Trade.Company is not null (so when a user selects a company). Would I need to create a custom converter to check for null and return the correct visibility or is there one in .NET?

    Hi all, I am learning how to use JQuery to help check data availability. I have written a function in a Controller for checking data input, and the URL is like this: http://www.mywebsite.com/controllers/action/avariable but the returned data was blank. <Script language="javascript"> $(document).ready(function(){ $(document).change(function(){ var usr = $("#data\\[User\\]\\[name\\]").val(); $.post{"http://www.mywebsite.com/controllers/action/", usr, function(msg){alert(msg);} } }); }); </Script> <div id="username"> <input type=text name="data[User][name]" id="data[User][name]"> </div> Here is the code of the Action: function action($data=null){ $this->autoRender = false; $result2=$this->__avail($udata); if($result2==1) {return "OK";} else {return "NOT";} }

  • Subsonic: Select on a View, locks the table update?

    - by Jay
    Hi, I have a Web site live and running now. I am using the Subsonic to handle the database connections etc. I am getting time out expired error while updating a table (say Employee). When I check sp_who2, I see the suspended connection for the PID which is updating with a block by anothor pid, so I run the profiler and found out when ever this suspended connection occur, the blocked pid is a select statement on the view (say ActiveEmployees, which is the same as the table but with some where conditions). Anyone know why a Select statement on the view could cause failure in update. If it is other (like select fails due to update) may be reasonable. Is there any way for me to make select on a view without locking the table? PS: I am using the Sql server 2005 and subsonic 2.2. Thanks

  • How to avoid recursion in Java SecurityManager checkConnect?

    - by Zilupe
    I'm trying to take control of a Java code base that does lots of un-documented things. I'm using a custom SecurityManager to check permission requests. Specifically, my code is checking SocketPermission checks -- checkConnect. checkConnect is called when the application tries to resolve a host name to IP address and to connect to a specific IP address. The problem is that I don't know how to properly call host name resolution (InetAddress.getAddressByName) without falling into infinite recursion, because normally checkConnect is called even when I resolve the name from inside the SecurityManager.checkConnect. I have read on the web that I have to call the address resolution from a doPrivileged block, but no idea how. P.S. Is this possible without writing any policy files?

  • What is the correct connection string for SQL 2000 server in entity framework

    - by M-Askman
    I success to use entity framework for MySQL but reverse code can not be used with SQL Server 2000, then i guess to change connection string to connect SQL Server 2000, however, got error <add name="BetterContext" connectionString="Data Source=server2;Initial Catalog=GoodDB;User ID=sa;Password=hello;MultipleActiveResultSets=True;" providerName="System.Data.SqlClient" /> An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct public partial class BetterContext : DbContext { static BetterContext() { Database.SetInitializer<BetterContext>(null); } public livefeedContext() : base("Name=BetterContext") { }

  • Request/Response pattern in SOA implementation

    - by UserControl
    In some enterprise-like project (.NET, WCF) i saw that all service contracts accept a single Request parameter and always return Response: [DataContract] public class CustomerRequest : RequestBase { [DataMember] public long Id { get; set; } } [DataContract] public class CustomerResponse : ResponseBase { [DataMember] public CustomerInfo Customer { get; set; } } where RequestBase/ResponseBase contain common stuff like ErrorCode, Context, etc. Bodies of both service methods and proxies are wrapped in try/catch, so the only way to check for errors is looking at ResponseBase.ErrorCode (which is enumeration). I want to know how this technique is called and why it's better compared to passing what's needed as method parameters and using standard WCF context passing/faults mechanisms?

  • What are my alternatives to manage Python packages for clients?

    - by c00kiemonster
    So the setup is a slew of proprietary server/client Python applications running on one Linux box (the server) and a set of Windows 7 workstations (the clients). Everything is running smoothly until any of the proprietary Python packages needs updating. For now I am using distutils eggs which are very easily updated with easy_install, but it is still a manual process which quickly becomes tedious as the number of applications and client workstations grow. The ideal setup IMHO is to have the Python packages on the server so when a client application is launched on a workstation the client application can check to see whether its current Python packages are up-to-date. If not, the client application should download the newer Python package from the server, install it, and then launch as per normal. Does this sounds familiar to anyone? I have tried to find alternatives myself, but as far as I can see there is no Python module offering this functionality. Does anyone have any home made solutions for this?

  • .htaccess causes links on page to try an open a BIN file?

    - by user1796820
    My friend's site which I agree to tech-advise, is psychtalkonline.com. You can go check it out, it's an anonymous forum (miniBBS) running Apache on Unix. I at first had a problem with mod_rewrite but then I uploaded the .htaccess file. However, that seemed to cause problems. If you click on any link, you will get a pop-up saying "You have chosen to open which is a BIN file". If you click the source code, and click on the links in the source code, you will see that it goes to the BIN file. I'm not really sure what's going on. I really would appreciate some help. Thanks.

  • Interpreting Accept Headers as intended in IE and Webkit

    - by Jrgns
    I developed a web app that responds with data in the format as specified by the client in the HTTP Accept Headers. Everything worked fine while using Firefox, but when I wanted to check my CSS / HTML on Chrome and IE, both of them wanted to download the index page, as if it's an unknown content type. After some research I found this article, which states that IE sends out a lot of crud in it's HTTP Accept headers, amongst others a list of image/* content types right at the start. This caused my web app to try to send the index page as an image/jpeg. So how do I know when to ignore and when to use the Accept Headers?

  • How does Facebook codes their Cropping tool?

    - by Trip
    I ask this because I am currently trying to work out my own technique, and there are huge strategic hangups for the entire site when your begin this. Of them are: Using jCrop and rMagick, it takes up a huge amount of processing ( to which I have backgrounded ). Because I have it backgrounded, I must by ajax develop a feature that auto-updates every five seconds to check when the backgrounding is done. Has anyone accomplished this with their sites? If so, what are some creative techniques you came across to keep the processing streamline, and the users happy?

  • RemoteWebDriver InternetExplorer navigate().to() timeout?

    - by the qwerty
    i was running a test remotely on internet explorer, and when using navigate().to() selenium returns me this: "12:13:58.770 INFO - WebDriver remote server: Exception: The driver reported that the command timed out. There may be several reasons for this. Check that the destinationsite is in IE's 'Trusted Sites' (accessed from Tools-Internet Options in the 'Security' tab) If it is a trusted site, then the request may have taken more thana minute to finish." i've done what's said. but when looking at the browsers the page is loaded, but still this message continues. i've already tried as simon told me: "(16:32:54) simonstewart: ponto: http://code.google.com/p/selenium/wiki/FrequentlyAskedQuestions#Q:_The_does_not_work_well_on_Vista._How_do_I_get_it_to_work_as_e " but did not solve. could it be google analytics that on the background is getting data or something like that? ps: i ran the test on firefox and it works well. i've tried on Windows 7 and Windows XP, and Internet Explorer 7 and Internet Explorer 8.

  • Is there a class like a Dictionary without a Value template? Is HashSet<T> the correct answer?

    - by myotherme
    I have 3 tables: Foos, Bars and FooBarConfirmations I want to have a in-memory list of FooBarConfirmations by their hash: FooID BarID Hash 1 1 1_1 2 1 2_1 1 2 1_2 2 2 2_2 What would be the best Class to use to store this type of structure in-memory, so that I can quickly check to see if a combination exists like so: list.Contains("1_2"); I can do this with Dictionary<string,anything>, but it "feels" wrong. HashSet looks like the right tool for the job, but does it use some form of hashing algorithm in the background to do the lookups efficiently?

  • How can a class's memory-allocated address be determined from within the contructor?

    - by Jim Fell
    Is it possible to get the memory-allocated address of a newly instantiated class from within that class's constructor during execution of said constructor? I am developing a linked list wherein multiple classes have multiple pointers to like classes. Each time a new class instantiates, it needs to check its parent's list to make sure it is included. If I try to do something like this: MyClass() // contructor { extern MyClass * pParent; for ( int i = 0; i < max; i++ ) { pParent->rels[i] == &MyClass; // error } } I get this error: error C2275: 'namespace::MyClass' : illegal use of this type as an expression Any thoughts or suggestions would be appreciated. Thanks.

  • RSpec: in-depth differences between before(:all) and before(:each)

    - by gmile
    Ok, so I've ran into a very strange issue, directly connected with before blocks. I'm doing a integration testing via Watir and RSpec. For a simple test to check if user can perform a login I'm creating a 'user' record in the db by means of factory_girl. So I put the following code: before(:each) do @user = Factory(:user) end if "should perform a login" do # do stuff end In do stuff I call a browser and see how the user tries to login. Unfortunately, somehow he cannot do that — "Username isn't valid". After some investigation I discovered that if I put the code for creating user in before(:all) block, everything magically works. How's that? What's the difference between :all and :each in this context? Also, If I put the code for creating user actually in the test body, it still doesn't work (i.e. user somehow isn't added to the DB or something).

  • How can I traverse a reverse generic relation in a Django template?

    - by user569139
    I have the following class that I am using to bookmark items: class BookmarkedItem(models.Model): is_bookmarked = models.BooleanField(default=False) user = models.ForeignKey(User) content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey() And I am defining a reverse generic relationship as follows: class Link(models.Model): url = models.URLField() bookmarks = generic.GenericRelation(BookmarkedItem) In one of my views I generate a queryset of all links and add this to a context: links = Link.objects.all() context = { 'links': links } return render_to_response('links.html', context) The problem I am having is how to traverse the generic relationship in my template. For each link I want to be able to check the is_bookmarked attribute and change the add/remove bookmark button according to whether the user already has it bookmarked or not. Is this possible to do in the template? Or do I have to do some additional filtering in the view and pass another queryset?

  • grab inspect the parameters to "use" and pass on the rest?

    - by JoelFan
    I have a Perl module and I'd like to be able to pick out the parameters that my my module's user passed in the "use" call. Whichever ones I don't recognize I'd like to pass on. I tried to do this by overriding the "import" method but I'm not having much luck. EDIT: To clarify, as it is, I can use my module like this: use MyModule qw/foo bar/; which will import the foo and bar methods of MyModule. But I want to be able to say: use MyModule qw/foo doSpecialStuff bar/; and look for doSpecialStuff to check if I need to do some special stuff at the beginning of the program, then pass qw/foo bar/ to the Exporter's import
