  • Convert an array of bytes into one decimal number as a string

    - by Martin Kirsche
    I'm trying to write function that converts an arbitrary large array of bytes (larger than 64-bit) into a decimal number represented as string in c# and I simply can't figure out how to do it. For example the following code ... Console.WriteLine(ConvertToString( new byte[] { 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88, 0x99, 0xAA, 0xBB, 0xCC, 0xDD, 0xEE, 0xFF, 0x00 })); .. should print out 22774453838368691933757882222884355840 I don't want to just use an extra library like biginteger for that, because I want it to be simple and like to understand how it works.

  • HTML overlay height to cover entire visible page

    - by Evgeny
    I have a web page that loads some stuff using AJAX. I want to display an overlay with a loading indicator while the loading is in progress, so that the user cannot interact with most of the page - except the menu at the top. I'm using jQuery and the jQuery BlockUI plugin to do this. I call $(element).block() and it works fine, but the overlay only extends as far down as the current content of my page. As more content is loaded and added to the page the overlay moves down with it and this looks a bit ugly. Ideally I'd like it to cover the entire visible area of the page right from the start. A simple hack for doing this would be to set a large height value for the overlay, like this: $(myElement).block({ overlayCSS: { height: '10000px' } }); ... but this creates a scrollbar! How do I avoid this and make it just the right height to cover the visible page, but not enlarge it?

  • EE Major : Should I learn Ruby on Rails or Haskell?

    - by Vivek
    Hi,I've just completed my freshman year in college and am majoring in EE (with a lot of interest in CS as well) . I know some Python,C/C++ and Java and also a little bit of Actionscript . I am planning to learn either Haskell or Ruby on Rails. Haskell because it is a functional programming language, and I've been really impressed by this paradigm and Ruby on Rails , as I don't know any 'web' programming language and have heard that you can develop apps in RoR very easily and quickly . Which one should I learn ? and please suggest some links / books for starting off .

  • ASP.NET GridView and UpdatePanel

    - by Echilon
    I have a GridView, inside a UserControl, inside an UpdatePanel on a page. There's a button in the GridView which needs to fire a postback. What happens is: User clicks button - RowCommand Fires - Custom event is raised on UserControl - Page detects this and changes the active view index for a multiview and also the page title and some other controls outside the UpdatePanel. The problem is, the page posts back asyncchronously, the page title changes, but the actions requireing a full postback don't happen because a full postback doesn't occur. To register the button as a postback trigger I'm using: ImageButton btnResults = e.Row.FindControl("btnResults") as ImageButton; ScriptManager scrCurrent = ScriptManager.GetCurrent(this.Page); if (btnResults != null && scrCurrent != null) { scrCurrent.RegisterPostBackControl(btnResults); } I know this is a bit of a complicated problem, but I'd really appreciate any help.

  • ruby on rails state machines

    - by srboisvert
    I'm looking to implement a state machine to manage a user moving through a series of steps over an extended period of time (weeks) with emails and then they interact with the app. I've looked at a couple of AASM plugins and forks (it seems like this plugin space has become a bit chaotic) and am curious what people would recommend. I saw the automatic AASM by hashrocket, that transitions states using cron, and from the title it looks like it might fit the bill but there doesn't appear to be any documentation anywhere and it looks more like a skeleton app than a plugin.

  • jQuery preventDefault stops rest of code working

    - by Tim
    I have this code where I am using jQuery to navigate to the next page, because I want some effects to take place before that happens. The problem is, that everything after the prevent.Default(); doesn't seem to work! $("a").click(function(event){ event.preventDefault(); $(".content-center").animate({height: "0px"}, 500); navigate($(this).attr('href')); }); I need things to happen in that order, so that the animation happens and once it's complete - load the next page... Does anyone have any ideas? Many thanks in advance? Tim Updated code (moves to new page but no animation occurs) --- $("a").click(function(event){ event.preventDefault(); var driver = $(this).attr('href'); $(".content-center").animate({ height: "0px" }, 500, function(){ navigate(driver); }); }); see: http://bit.ly/aOeYgE Many thanks for your help!!

  • Are there any serialization frameworks for java

    - by Grofit
    I know there is simple, which seems to be a decent enough XML serializer and i know there is Jaxb which seems to do the job as well. However im after something a bit more generic, so I could serialize my model to Xml, Json, Binary etc. So the models are just dumb objects that just get thrown into some sort of serialization factory and then the relevant output is spat out... I dont see any reason why you couldn't do this with reflection, so for a REALLY simple solution get the relevent public properties, cut off the get or set and make that the element name... i.e getPersonName() would become <PersonName>xxxx</PersonName> or PersonName:XXXXX

  • noob question : reading xml from url link by using php

    - by mireille raad
    Hello, I am trying to build an authentication plugin that uses php/xml. My application can communicate to another application by sending this : http://tst.example.net/remote/validate_user.jhtml?ticket=$ticket_value in return i get a formatted xml document. i want to be able to parse that document. I googled and read a bit around here , but what i could find is that using php_simplexml i can do the following $xml = simplexml_load_file("test.xml"); echo $xml-getName() . ""; foreach($xml-children() as $child) { echo $child-getName() . ": " . $child . ""; } my question is : i don't have a test.xml file, it is a url that i am reading/parsing, any way how to get the info from the url, not a file. I know this is a very noobish question, i would appreciate the help

  • how to calculate a bill from several tables on mysql?

    - by Audel
    I'm using mysql to create an hotel booking system, but i am struggling a little bit to calculate the final bill. I need a SELECT command to get data from several tables and make some calculations. Basically I just need to get the 'night cost' from a table called 'room_types'. Then, use DATEDIFF function to get the difference of days between the 'checkin' and 'checkout' columns in the table 'room_booking' and multiply the difference with the night cost and display the total. These are the tables I would be using: are room_booking, room_types, booking, and room. One booking may have several room bookings, so Im looking for a table that looks something like this: +------------+------------+---------------+------------------+ | bookingid | Room price | nights stayed | total room price | +------------+------------+---------------+------------------+ | B001 | 30.00 | 4 | 120.00 | +------------+------------+---------------+------------------+ | B001 | 40.00 | 3 | 120.00 | +------------+------------+---------------+------------------+ booking id comes from table 'booking' room price from 'room_types', 'nights stayed' is calculated from the table room_booking, using the datediff command between checkin and checkout . I hope i was clear

  • Access to Apache::DBI from DBI

    - by hpavc
    Is it possible to access a Apache::DBI database handle from a perl script (that isn't running under mod_perl). What I am looking for is database pooling for my perl scripts, I have a fair number of database sources (oracle/mysql) and a growing number of scripts. Some ideas like SQLRelay, using Oracle10XE with database links and pooling, and or convert all scripts to SOAP calls, etc are becoming more and more viable. But if there was a mechanism for reusing Apache::DBI I could fight this a bit. I have no non-perl requirements, so we don't have a php/jdbc implementation or similar to deal with. Thanks

  • Adding js to a drupal node form

    - by googletorp
    In Drupal you can create your own nodetype in a custom module. Doing this you get to create your own form which is all very nice. However if you want to add js the form things get a bit more tricky. If you add the js in the form, the js will only be added form the form when it is loaded. If the user would post the form with validation errors, the form function is not run again and thus the js is not added. Normally you would just create a menu callback and add the js there, but for the node add form, this wont be a possible solution. So what is the best solution for adding js in a node add form, to keep it persistant when the form doesn't validate?

  • Step-by-step execution for Intel AT&T assembler?

    - by Søren Haagerup
    Hello everyone, I'm writing a compiler that converts source code (written in a small imperative programming language) to Intel AT&T 32-bit assembler. I tend to spend a lot of time debugging, because of nasty offset-mistakes etc. in the generated code, and I would like to know if anyone knows of a tool to "walk through" the generated assembler code step-by-step, visualizing what's on the stack etc. I use Ubuntu Linux as my development platform, and I'm comfortable with the terminal -- a GUI-program would be nice though. Does it exist? Or is there a good reason it doesn't (maybe the problem isn't so straightforward..?) If you have good ideas for approaching debugging tasks in assembly code, I'll be glad to hear from you!

  • Do I always have to provide Tkx's -command argument an anonymous subroutine?

    - by Zaid
    I find it a bit weird that I have to wrap defined subroutines anonymously when specifying the -command argument for Tkx widgets. An excerpt from a TkDocs tutorial demonstrates this: my $cb = $frm->new_ttk__button ( -text => "Calculate", -command => sub {calculate();} ); sub calculate { $meters = int(0.3048*$feet*10000.0+.5)/10000.0 || ''; } Why doesn't it work when I write -command => &calculate() or -command => \&calculate()?

  • Hardest javascript debugging problem ever

    - by Craig
    We have an ASP.NET application and when running on client site they often get null reference Javascript errors. As with all these errors the information IE6 displays is less than helpful. But the problem is as soon as I install IE script debugger and try and debug a bit more the error becomes non-reproducible.When script debugger is not installed then the error occurs again. Are there any other tools that could be helpful for javascript debugging on client site. The error is also not produced with IE7 or Firefox.

  • How to use NSString drawInRect to centre text?

    - by Steve Folly
    How can I draw a string centred within a rect? I've started off with: (an extract from the drawRect method of my custom view) NSString* theString = ... [theString drawInRect:theRect withAttributes:0]; [theString release]; Now I'm assuming I need to set up some attributes. I've had a look through Apple's Cocoa documentation, but it's a bit overwhelming and can't find anything for how to add paragraph styles to the attributes. Also, I can only find horizontal alignment, what about vertical alignment? Thanks.

  • Winform BindingSources - Question

    - by Stephen Patten
    I have a windows form (net 2.0) with controls on it bound to an entity (w/ INotifyPropertyChanged) through a BindingSource..works. On the same form I have a drop down list that is also wired up through a BindingSource..works Here's a sample of the relevant code: m_PlanItemLookupBindingSource.DataSource = GetBusinessLogic().RetrievePaymentPlanLookups(); // Collection of PaymentPlans paymentPlanType.Properties.DataSource = m_PlanItemLookupBindingSource; paymentPlanType.Properties.DisplayMember = "Name"; paymentPlanType.Properties.ValueMember = "ID"; paymentPlanType.DataBindings.Add(new Binding("EditValue", m_PlanBindingSource, "PaymentPlanID", true, DataSourceUpdateMode.OnPropertyChanged, null, "D")); agencyComission.DataBindings.Add(new Binding("EditValue", m_PlanBindingSource, "AgencyCommission", true, DataSourceUpdateMode.OnPropertyChanged, null, "P1")); billingType.DataBindings.Add(new Binding("Text", m_PlanBindingSource, "BillingType")); So when I change a value in the drop down list I thought that the m_PlanItemLookupBindingSource Current property would change along with the PaymentPlanID property of the entity which does change. Just a bit confused. Thanks in advance, Stephen

  • C# Custom Dictionary Take - Convert Back From IEnumerable

    - by Goober
    Scenario Having already read a post on this on the same site, which didn't work, I'm feeling a bit stumped but I'm sure I've done this before. I have a Dictionary. I want to take the first 200 values from the Dictionary. CODE Dictionary<int,SomeObject> oldDict = new Dictionary<int,SomeObject>(); //oldDict gets populated somewhere else. Dictionary<int,SomeObject> newDict = new Dictionary<int,SomeObject>(); newDict = oldDict.Take(200).ToDictionary(); OBVIOUSLY, the take returns an IENumerable, so you have to run ToDictionary() to convert it back to a dictionary of the same type. HOWEVER, it just doesn't work, it wants some random key selector thing - or something? I have even tried just casting it but to no avail. Any ideas?

  • How does a syscall knows where the wrapper function put its parameters in?

    - by EpsilonVector
    I'm trying to implement a syscall in Linux (RedHat Enterprise 8) and I'm a bit confused about the way it works. From what I understand, I implement a wrapper in user mode which puts the syscall number in eax and parameters in ebx, ecx, edx, etc, and then invokes int 0x80 which calls the appropriate syscall. My question is, since a syscall is written like a regular C function, how does it know what registers contain what parameters? Is it a convention, or is there a mechanism for it, and if so where and how does it do it?

  • Choosing a source control system: logical next steps after VSS

    - by Dave
    I've been using Git for the past few months and love it. I looked into how to host it in a corporate environment. Considering a 10 person team who use Visual SourceSafe, programming in Coldfusion, Powerbuilder, PHP and a bit of .NET, I found, to my surprise, that the Git 'server' tooling is still fairly rudimentary. http://stackoverflow.com/questions/1761054/git-in-a-company-hosting-own-server Question Apart from SVN, what other source control options would be a logical next step after VSS? Paid options are fine. Something with nice tooling, that isn't scary would be great :-)

  • Show blank UITableViewCells in custom UITableView

    - by Typeoneerror
    I am trying to customize a UITableView. So far, it looks good. But when I use a custom UITableViewCell sub-class, I do not get the blank table cells when there's only 3 cells: Using the default TableView style I can get the repeating blank rows to fill the view (for example, the mail application has this). I tried to set a backgroundColor pattern on the UITableView to the same tile background: UIColor *color = [UIColor colorWithPatternImage:[UIImage imageNamed:@"score-cell-bg.png"]]; moneyTableView.backgroundColor = color; ...but the tile starts a bit before the TableView's top, so the tile is off once the actual cell's are done displaying: How can I customize my tableview but still keep the blank rows if there's less rows than fill a page?

  • DataSource for Tomcat web app, Spring and Hibernate

    - by EugeneP
    Web app runs on Tomcat. Datasource is configured with Spring configuration, and is used by Hibernate. If we cannot use JNDI, what would you suggest to use as a DataSource? org.springframework.jdbc.datasource.DriverManagerDataSource will be ok? It's not very good, but sincerely speaking, it can be used on production server, right? Just a bit of headache with too frequent connection reopening. Also, we can use BasicDataSource from Apache. It's much better of course, but here's the question. IF WE DON'T USE JNDI, THEN: If every instance of an app will create its own copy of a DataSource, and every DataSource can have 5 open connections, what do we get? Num_of_running_apps * Num_of_max_active_connections = max active open connection on a DB for this user? Second question: from the perspective of Hibernate, is there any difference about what datasource implementation is used? Will it work with no matter what datasource perfectly and in a stable way?

  • Linq to sql add/update in different methods with different datacontexts

    - by Kurresmack
    I have to methods, Add() and Update() which both create a datacontext and returns the object created/updated. In my unit test I call first Add(), do some stuff and then call Update(). The problem is that Update() fails with the exception: System.Data.Linq.DuplicateKeyException: Cannot add an entity with a key that is already in use.. I understand the issue but want to know what to do about it? I've read a bit about how to handle multiple datacontext objects and from what I've heard this way is OK. I understand that the entity is still attached to the datacontext in Add() but I need to find out how to solve this? Thanks in advance

  • using MODI in C# to read image - numbers with a length of 1 is missing

    - by keysersoze
    I am about building an C#-application in which I am trying to read text from an gif-image (OCR) - I am using MODI and the images are a bit like a lotto coupon (random numbers in rows and columns). I now got the following code which read all numbers except single numbers (1, 2, 3...) MODI.Document objModi = new MODI.Document(); objModi.Create("C:\\image.gif"); objModi.OCR(MODI.MiLANGUAGES.miLANG_DANISH, true, true); MODI.Image image = (MODI.Image)objModi.Images[0]; MODI.Layout layout = image.Layout; I cannot change the content of the image but can I do anything with the above code so it can read the single numbers?

  • Populating an association with children in factory_girl

    - by Craig Walker
    I have a model Foo that has_many 'Bar'. I have a factory_girl factory for each of these objects. The factory for Bar has an association to Foo; it will instantiate a Foo when it creates the Bar. I'd like a Factory that creates a Foo that contains a Bar. Ideally this Bar would be created through the :bar factory, and respect the build strategy (create/build) used to create the Foo. I know I could just call the :bar factory and then grab the Foo reference from the new Bar. I'd like to avoid this; in my test case, the important object is Foo; calling the Bar factory seems a bit circuitous. Also, I can see the need for a Foo with multiple Bars. Is this possible in factory_girl? How do you define this relationship in the parent?

  • Why does installing NVidia 9600GT graphics card, take 1GB of RAM away from Windows?

    - by Nick G
    Hi, I've changed graphics cards in my PC and now Windows 7 (32bit) is reporting that I have a whole gigabyte less physical RAM in my PC. Why is this? Firstly, the machine has 4GB of physical RAM. The old card was an ATI 2600XT with 256MB and the new card is an NVidia 9600GT with 512MB. With the ATI card windows sees 3326MB. With the NVidia card, windows sees 2558MB. I realise that due to address space restrictions I will not see all 4GB with 32bit windows, but why is there such a massive loss of RAM when simply changing cards (bearing in mind BOTH cards have their own RAM and borrow no main memory like some built on chipsets do). Would using 64 bit windows solve this? Thanks Nick.
