  • .NET desktop App remembering login to a webservice

    - by pete the pagan-gerbil
    I am in the planning stages of a .NET desktop app that will communicate with a web service. The web service requires a username and password, and a common feature in this sort of app is to save the user's credentials for the next logon. I've thought of a few ways of achieving this, but I am not sure what the most secure way would be. Should it be stored encrypted in a file (and could someone nefarious copy that file to their own machine and hence logon as the original person), or in the registry somehow (I've not done any registry work before, is it secure and would it work)? Are there any other options I might not have thought of?

  • Extract string that is delimited with constant and ends with two numbers (numbers have to be included)

    - by Edmon
    I have a text that contains string of a following structure: text I do not care about, persons name followed by two IDs. I know that: a person's name is always preceded by XYZ code and that is always followed by two, space separated numbers. Name is not always just a last name and first name. It can be multiple last or first names (think Latin american names). So, I am looking to extract string that follows the constant XYZ code and that is always terminated by two separate numbers. You can say that my delimiter is XYZ and two numbers, but numbers need to be part of the extracted value as well. From blah, blah XYZ names, names 122322 344322 blah blah I want to extract: names, names 122322 344322 Would someone please advise on the regular expression for this that would work with Python's re package.

  • Reporting. MS Word templates population required

    - by Andrew Florko
    Application we developed fills MS Word templates with data from Database. Customers require to have ability edit Word templates via MS Word (change style, font, layout e.t.c) with no additional software to be installed and no training. AFAIK, Sql Reporting Services and Crystal Reports can't populate MS Word templates produced in MS Word. So we implemented our custom solution that maps .net classes onto xml-saved MS Word documents. It looks like we declare class MyTemplate { // maps to [age] field declared in ms document straight in the text int Age { get; set; } // maps to table by attributes applied to property (omitted) List<Person> Persons { get; set; } } We also implemented images insertion. Are there any free libraries for this task or may be you use your own MS-word templators in your projects?

  • SQL query to get field value distribution (mode)

    - by Bryan Lewis
    I have a table of over 1 million test score records that basically have a unique score_ID, a subject_ID and a score given by a person. The score range for most subjects is 0-3, but some have a range of 0-4. There are about 25 possible subjects. I need to produce a score distribution report which looks like: subject_ID 0 1 2 3 4 ---------- --- --- --- --- --- 1 967 576 856 234 2 576 947 847 987 324 . . So it groups the data by subject_ID, then shows how many times a specific score value was given within that subject. Any SQL pointers to generate this would be greatly appreciated.

  • How to grab all cookies in Flash

    - by Leticia Meyer
    For a site I'm developing with a user login that uses cookies to store the session ID, a separate section of it uses Flash to provide content and such. Is there some way it can access the cookies that were set the by login? The name of the cookie will not the be same every time, as it is randomly generated, as well as its value. I then need to send the name and value of the cookie back to a page on the server to do additional stuff. Anyone know how to do this? Note that I didn't write the Flash interface, an the person who did doesn't know how to do this. Please help me, and thanks in advance!

  • Django and a referrer system question

    - by Hellnar
    Hello, I am trying develop a basic referrer system to my Django website, system will be generating a unique url for each users to share with their friends. Once these friends enter this website, system somehow keep the data that "this user is browsing by the reference of X user" and once this invited person decided to register for an account, system will save this information (maybe as an extra Foreign Key of the inviting user in the UserProfile model) Now how can I keep track of the inviting user from the moment entering using the referred link to the point where he/she registers to the site. Would session framework work on this? If not how could this be done ?

  • Track Pedestrians

    - by 2vision2
    I am using OpenCV sample code “peopledetect.cpp” to detect and track pedestrians. The code uses HoG for feature extraction and SVM for classification. Please find the reference paper used here. The camera is mounted on the wall at a height of 10 feet and 45 degree down. There is no restriction on the pedestrian movement within the frame. I want to track the detected pedestrians’ movement within the frame. The issue I am facing is pedestrians are detected only in the middle region of the frame as most of the features are not visible as soon as the pedestrian enters the frame region. I want to track each person’s movement in the entire frame region. How to do it? Is tracking required? Can anyone give any reference to blogs/codes?

  • Backdoor Strategy- opinion needed.

    - by the Hampster
    I'm creating an application to track publications and grants for a university. Professors will need to put they CV into the system when it is up and running. Yeah, right. The person in charge is planning on hiring someone to input all of the information, but my questions is how? The strategy I'm thinking of is to install a backdoor. The lucky undergrad can log in as any professor using the backdoor. Once all the data is removed, the backdoor can be removed. Doing so would probably be as simple as editing out a comment in the config file. The IT guys would still have access, but since they control the machines, they would have access anyway. Are there any flaws to this strategy?

  • How Likely Is It That I'll Get Sued Developing Software?

    - by yar
    It has been a practically unanimous truth on StackOverflow that if you work as an independent consultant, you should probably form a corporation (as seen here), to limit personal liability, supposedly to protect you in case of lawsuit. It seems to me that developing software does not result in many lawsuits, but this is an empirical (objective [and not community wiki]) question: How likely is it that a lone software developer will be sued? Also, by whom (a disgruntled company, coworker)? Since incorporating is basically taking out insurance, the likelihood of catastrophe needs to be taken into account. Also, aren't there standard laws covering, for example, total screw-ups with corporate data that mean that protect the lone cowboy/girl/person/coder?

  • VS2005 and VSS. Should .exes, .dlls, pdbs, .resource and generated .xml files go in VSS?

    - by Velika
    It seems like the following type of files need to be writable to be able to compile a solution. .exe .dll .pdb (if debugging) .resource (?) .xml (at least the system generated ones. I'm not sure if they are just all XML documentationf iles) If they were checked in and could only be overwritten by the compiler by the person who had them checked out, then checking them into sourcesafe and requiring a checkout to modify them, which is attemtped by the compiler each time you run, would interfer with other developer's ability to debug and run. What is the best practice? It seems like VSS automatically adds everything.

  • I want to retrieve some information based on Caller ID

    - by Hassan Al-Jeshi
    Hello, my friend has a Real Estate company that receives a lot of phone calls everyday. He wants to have a solution such that when somebody call to his company, the operator sees all the information about the person who is calling based on the database he have right now and the caller ID. Is there a ready made software or solution that can do the job?? Since I'm a software engineer myself, I would never mind developing something from scratch or built on a ready made system (with a team of course), but I need some direction on how to start?? Notes: 1- cost is not an issue 2- the customers database is there but we never mind replacing it in a format to suit the new solution Best Regards,

  • Using Html.LabelFor to display human readable label?

    - by Shay Friedman
    I'm using ASP.NET MVC 2 and I'm struggling to understand how can I use the Html.LabelFor helpet method. Assuming I have a model: public class Person { public string FirstName { get; set; } } In my view, if I write: <%: Html.LabelFor(model => model.FirstName) %> What I get on the page is "FirstName". But I don't want that because it's now user-friendly. I want it to be "First Name". How do I achieve that? Thanks.

  • Match an element of an array to a different element in that array

    - by Anh
    I have an array containing several students. I want them to cross-grade one another randomly, i.e. each student will grade someone and will be graded by someone else (these two people may or may not be the same person). Here is my working solution. I'm sure there is a more elegant answer! def randomize(student_array) graders = student_array.dup gradees = student_array.dup result = {} graders.each do |grader| gradee = grader while gradee == grader gradee = gradees.sample end result[grader] = gradee gradees.delete_at(gradees.index(gradee)) end return result end

  • How to use anonymous types with Netflix OData API

    - by obautista
    If I create this collection: IEnumerable<_TITLE> _titles = null; How can I set the result set from Netflix in this expression: _titles = from t in Titles where t.Id == "ApUFq" select new {t, t.Cast} I am getting: Cannot implicitly convert type 'System.Linq.IQueryable' to 'System.Collections.Generic.IEnumerable<_Title'. An explicit conversion exists (are you missing a cast?) I understand it's because I am using an anonymous type. _TITLE is a custom complex object I create that exposes a subset of Netflix properties. If I add "_TITLE" in front the of the "new" it says that my object does not implement IENUMBERABLE. If then _TITLE implements IENUMBERABLE, it says _TITLE does not contain a definition for ADD and still getting conversion error. Basically, I want to set the _TITLE properties with the data returned from Netflix. I have defined _TITLE to contain the fields I need, plus a collection of PERSON (for Cast).

  • Linq to SQL inheritance and Table per Class - approach needed for multiple roles

    - by Ash Machine
    I am using L2S and an inheritance model for mapping Persons against certain roles. Guy Burstein's excellent blog post explains how to accomplish this: http://blogs.microsoft.co.il/blogs/bursteg/archive/2007/10/01/linq-to-sql-inheritance.aspx However, I have a specific case where a Person has multiple roles. For example 'Jane Doe' is a Contact and a Programmer. In this model, she would need two rows in the People table, one as Contact (PersonType = 1) and one as Programmer (PersonType = 3). If she changes her last name, and that update happens in her role as Contact, I would need to change all instances of 'Jane Doe' to reflect the name change everywhere. What sort of best approach (improved data structure) could be used to change last name within all roles? Finally, I am hoping to avoid overriding each general form update events to include all instances, but that may be the only way. Any suggestions or approaches appreciated.

  • What traits can hint a teenager he should pursue software development career?

    - by sharptooth
    We're gonna have a day when employees' kids will visit our company office. The idea is that they will come see "how parents work", "how cool stuff is done", have fun, etc. Kids will be up to 17 years old. Now I suppose some of the teenagers already think of what they wanna do when they finally grow up and will ask questions like "how can I tell I should get a degree in software engineering and not in logistics/finances/whatever?" So I think we better be prepared and ready to answer those questions so that those who really fit don't waste time but use their potential to the full. What traits that already emerge in teenage years indicate that a person could become a very good software developer?

  • Getting data into an input field from YUI Calendar with multi-select:true

    - by kylex
    <script type="text/javascript"> YAHOO.util.Event.onDOMReady(function(){ YAHOO.dateSelects.exc = new YAHOO.widget.Calendar("exc","excContainer", { title:"Choose a date:", close:true, multi_select:true }); YAHOO.dateSelects.exc.render(); YAHOO.util.Event.addListener( "excshowup", "click", YAHOO.dateSelects.exc.show, YAHOO.dateSelects.exc, true ); }); </script> <div class="calendarOuterContainer"> <div id="excContainer" class="calendarContainer"></div> </div> <a id="excshowup"><img src="/images/icons/calendar.png" /></a> The preceding code generates a YUI calendar with the ability to select multiple dates on one calendar. What I am having trouble figuring out is how to capture that data and place it inside a text input tag on the fly. So when a person clicks the close button, all the selected dates are populated inside the input tag. Suggestions?

  • GEM Version Requirements Depreciated

However, if I add any gems to my environment.rb: config.gem "authlogic" And run the same generator, I get the following: /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/rails/gem_dependency.rb:119:Warning: Gem::Dependency#version_requirements is deprecated and will be removed on or after August 2010. The warning just recently appeared (I think), but I would like to fix it if possible. Any hints or similar experiences? Thanks.

  • What are the exact versions of stuff you have to install in order to be able to step-debug a Scala p

    - by Alex R
    How do YOU debug a Scala program? I mean YOU as in the person posting the Answer :) Please answer only from personal experience, not from stuff you've heard or read on the Internet. You should not believe everything you read on the Internet, especially tales of complex open-source software configurations that actually work :-) The are many Java tools which claim to support Scala in some way or another, but I have so far struck out in trying to get any one of them to actually let me set a breakpoint in Scala code and step through it. These are big, major open-source IDEs I'm talking about here. The main problem in getting a debugger to work seems to be the "version hell" with fast-changing IDEs, Plug-Ins, JDKs, and the Scala language itself. Hence, the more detailed re-statement of the question is appropriate: What is the exact version number of the IDE, Plug-In, JDK, Scala, and even Operating System, that you are successfully using? My question is related to this one, but wider in scope: http://stackoverflow.com/questions/2272705/how-to-debug-scala-code-when-outside-of-an-ide Thanks

  • Alternates to C++ Reference/Pointer Syntax

    - by Jon Purdy
    What languages other than C and C++ have explicit reference and pointer type qualifiers? People seem to be easily confused by the right-to-left reading order of types, where char*& is "a reference to a pointer to a character", or a "character-pointer reference"; do any languages with explicit references make use of a left-to-right reading order, such as &*char/ref ptr char? I'm working on a little language project, and legibility is one of my key concerns. It seems to me that this is one of those questions to which it's easy for a person but hard for a search engine to provide an answer. Thanks in advance!

  • One account, multiple users, multiple shopping cart in a web application

    - by lemotdit
    I received a somewhat unusual request (imo) for a transactional web site. I have to implement the possibility of having multiple shopping cart for the same user. Those really are shopping carts, not order templates. I.E: A store with several departments ordering under the same account, but with a different person placing orders for a specific department only. Having more than one user per account is not an option since it would involve 'too much' management from the stores owner and the admins. Anyone had to deal with this before? The option so far is to have names for shopping cart, and a dropdown list or something alike after login to choose the cart with some kind of 'busy flag' to lock the cart if it's in use in another session.

  • Hidden Features of Google Guice

    - by Jon
    Google Guice provides some great dependency injection features. I came across the @Nullable feature recently which allows you to mark constructor arguments as optional (permitting null) since Guice does not permit these by default: e.g. public Person(String firstName, String lastName, @Nullable Phone phone) { this.firstName = checkNotNull(firstName, "firstName"); this.lastName = checkNotNull(lastName, "lastName"); this.phone = phone; } http://code.google.com/p/google-guice/wiki/UseNullable What are the other useful features of Guice (particularly the less obvious ones) that people use?

  • Qlikview joins that dosen't join on all matching column names

    - by Dev_Karl
    Hi! I'm new to Qlikview and looking for some answers regarding scripting. How can I create Qlickview joins that just join on a specific column (and not all that are having a matching name)? Let's say that I'm having the following tables: Employee Id | Person | DepartmentID | Flags 1000 , Bob , 2001 , 1000000 1001 , Sue , 2002 , 1100000 Department Id | Name | Flags 2001 , HR , 01101111 2001 , R&D , 1100000 What is the best way of joining those tables on the DepartmentID <- ID field? The data is provided by SQL selects. I'm thinking of writing SQL views using unique names would be one idea, but there must be a simpler way. Please advice Kind regards, Karl
