  • jquery click on anchor element forces scroll to top?

    - by Dan.StackOverflow
    http://stackoverflow.com/questions/720970/jquery-hyperlinks-href-value[link text][1] I am running in to a problem using jquery and a click event attached to an anchor element. [1]: http://stackoverflow.com/questions/720970/jquery-hyperlinks-href-value "This" SO question seems to be a duplicate, and the accepted answer doesn't seem to solve the problem. Sorry if this is bad SO etiquette. In my .ready() function I have: jQuery("#id_of_anchor").click(function(event) { //start function when any update link is clicked Function_that_does_ajax(); }); and my anchor looks like this: <a href="#" id="id_of_anchor"> link text </a> but when the link is clicked, the ajax function is performed as desired, but the browser scrolls to the top of the page. not good. I've tried adding: event.preventDefault(); before calling my function that does the ajax, but that doesn't help. What am I missing? Clarification I've used every combination of return false; event.preventDefault(); event.stopPropagation(); before and after my call to my js ajax function. It still scrolls to the top.

  • MATLAB intersection of 2 surfaces

    - by caglarozdag
    Hi everyone, I consider myself a beginner in MATLAB so bear with me if the answer to my question is an obvious one. Phi=0:pi/100:2*pi; Theta=0:pi/100:2*pi; [PHI,THETA]=meshgrid(Phi,Theta); R=(1 + cos(PHI).*cos(PHI)).*(1 + cos(THETA).*cos(THETA)); [X,Y,Z]=sph2cart(THETA,PHI,R); surf(X,Y,Z); %display hold on; x1=-4:.1:4; [X1,Y1] = meshgrid(x1); a=1.8; b=0; c=3; d=0; Z1=(d- a * X1 - b * Y1)/c; shading flat; surf(X1,Y1,Z1); I have written this code which plots a 3d cartesian plot of a plane intersecting a peanut shaped object at an angle. I need to get the intersection of these on 2D (going to be the outline of a peanut, but a bit skewed since the intersection happens at an angle), but don't know how. Thanks

  • How Do You Get the bufspec While Using Vimdiff Through Git

    - by Elizabeth Buckwalter
    I've read Vimdiff and Viewing differences with Vimdiff plus doing various google searches using things like "vimdiff multiple", "vimdiff git", "vimdiff commands" etc. When using do or diffg I get the error "More than two buffers in diff mode, don't know which one to use". When using diffg v:fname_in I get "No matching buffer for v:fname_in". From the vimdiff documentation: :[range]diffg[et] [bufspec] Modify the current buffer to undo difference with another buffer. If [bufspec] is given, that buffer is used. If [bufspec] refers to the current buffer then nothing happens. Otherwise this only works if there is one other buffer in diff mode. and more: When 'diffexpr' is not empty, Vim evaluates to obtain a diff file in the format mentioned. These variables are set to the file names used: v:fname_in original file v:fname_new new version of the same file v:fname_out resulting diff file So, I need to get the name of bufspec, but the default variables (fname_in, fname_new, and fname_out) aren't set. I ran the command git mergetool on a linux box through a terminal. [Edit] A partial solution that bred more questions. I used the "filename" at the bottom of the buffer. It's only a half answer, because occasionally I get a file does not exist error. I believe it's consistently the remote version of the file that "does not exist". I suspect this has something to do with git and indexing. How do you get the bufspec value consistently while using vimdiff through git-mergetool?

  • AndEngine VS Android's Canvas VS OpenGLES - For rendering a 2D indoor vector map

    - by Orchestrator
    This is a big issue for me I'm trying to figure out for a long time already. I'm working on an application that should include a 2D vector indoor map in it. The map will be drawn out from an .svg file that will specify all the data of the lines, curved lines (path) and rectangles that should be drawn. My main requirement from the map are Support touch events to detect where exactly the finger is touching. Great image quality especially when considering the drawings of curved and diagonal lines (anti-aliasing) Optional but very nice to have - Built in ability to zoom, pan and rotate. So far I tried AndEngine and Android's canvas. With AndEngine I had troubles with implementing anti-aliasing for rendering smooth diagonal lines or drawing curved lines, and as far as I understand, this is not an easy thing to implement in AndEngine. Though I have to mention that AndEngine's ability to zoom in and pan with the camera instead of modifying the objects on the screen was really nice to have. I also had some little experience with the built in Android's Canvas, mainly with viewing simple bitmaps, but I'm not sure if it supports all of these things, and especially if it would provide smooth results. Last but no least, there's the option of just plain OpenGLES 1 or 2, that as far as I understand, with enough work should be able to support all the features I require. However it seems like something that would be hard to implement. And I've never programmed in OpenGL or anything like it, but I'm willing very much to learn. To sum it all up, I need a platform that would provide me with the ability to do the 3 things I mentioned before, but also very important - To allow me to implement this feature as fast as possible. Any kind of answer or suggestion would be very much welcomed as I'm very eager to solve this problem! Thanks!

  • What scalability problems have you solved using a NoSQL data store?

    - by knorv
    NoSQL refers to non-relational data stores that break with the history of relational databases and ACID guarantees. Popular open source NoSQL data stores include: Cassandra (tabular, written in Java, used by Facebook, Twitter, Digg, Rackspace, Mahalo and Reddit) CouchDB (document, written in Erlang, used by Engine Yard and BBC) Dynomite (key-value, written in C++, used by Powerset) HBase (key-value, written in Java, used by Bing) Hypertable (tabular, written in C++, used by Baidu) Kai (key-value, written in Erlang) MemcacheDB (key-value, written in C, used by Reddit) MongoDB (document, written in C++, used by Sourceforge, Github, Electronic Arts and NY Times) Neo4j (graph, written in Java, used by Swedish Universities) Project Voldemort (key-value, written in Java, used by LinkedIn) Redis (key-value, written in C, used by Engine Yard, Github and Craigslist) Riak (key-value, written in Erlang, used by Comcast and Mochi Media) Ringo (key-value, written in Erlang, used by Nokia) Scalaris (key-value, written in Erlang, used by OnScale) ThruDB (document, written in C++, used by JunkDepot.com) Tokyo Cabinet/Tokyo Tyrant (key-value, written in C, used by Mixi.jp (Japanese social networking site)) I'd like to know about specific problems you - the SO reader - have solved using data stores and what NoSQL data store you used. Questions: What scalability problems have you used NoSQL data stores to solve? What NoSQL data store did you use? What database did you use before switching to a NoSQL data store? I'm looking for first-hand experiences, so please do not answer unless you have that.

  • How to set up a user Quartz2D coordinate system with scaling that avoids fuzzy drawing?

    - by jdmuys
    This topic has been scratched once or twice, but I am still puzzled. And Google was not friendly either. Since Quartz allows for arbitrary coordinate systems using affine transform, I want to be able to draw things such as floorplans using real-life coordinate, e.g. feet. So basically, for the sake of an example, I want to scale the view so that when I draw a 10x10 rectangle (think a 1-inch box for example), I get a 60x60 pixels rectangle. It works, except the rectangle I get is quite fuzzy. Another question here got an answer that explains why. However, I'm not sure I understood that reason why, and moreover, I don't know how to fix it. Here is my code: I set my coordinate system in my awakeFromNib custom view method: - (void) awakeFromNib { CGAffineTransform scale = CGAffineTransformMakeScale(6.0, 6.0); self.transform = scale; } And here is my draw routine: - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGRect r = CGRectMake(10., 10., 11., 11.); CGFloat lineWidth = 1.0; CGContextStrokeRectWithWidth(context, r, lineWidth); } The square I get is scaled just fine, but totally fuzzy. Playing with lineWidth doesn't help: when lineWidth is set smaller, it gets lighter, but not crisper. So is there a way to set up a view to have a scaled coordinate system, so that I can use my domain coordinates? Or should I go back and implementing scaling in my drawing routines? Note that this issue doesn't occur for translation or rotation. Thanks

  • Creating instance of a service-side DataContract class on client-side in WCF

    - by hgulyan
    Hi, I have my custom class Customer with its properties. I added DataContract mark above the class and DataMember to properties and it was working fine, but I'm calling a service class's function, passing customer instance as parameter and some of my properties get 0 values. While debugging I can see my properties values and after it gets to the function, some properties' values are 0. Why it can be so? There's no code between this two actions. DataContract mark workes fine, everything's ok. Any suggestions on this issue? I tried to change ByRef to ByVal, but it doesn't change anything. Why it would pass other values right and some of integer types just 0? Maybe the answer is simple, but I can't figure it out. Thank You. <DataContract()> Public Class Customer Private Type_of_clientField As Integer = -1 <DataMember(Order:=1)> Public Property type_of_client() As Integer Get Return Type_of_clientField End Get Set(ByVal value As Integer) Type_of_clientField = value End Set End Property End Class <ServiceContract(SessionMode:=SessionMode.Allowed)> <DataContractFormat()> Public Interface CustomerService <OperationContract()> Function addCustomer(ByRef customer As Customer) As Long End Interface type_of_client properties value is 6 before I call addCustomer function. After it enters that function the value is 0. UPDATE: The issue is in instance creating. When I create an instance of a class on client side, that is stored on service side, some of my properties pass 0 or nothing, but when I call a function of a service class, that returns a new instance of that class, it works fine. What's is the difference? Could that be serialization issue?

  • Why isn't my WPF Datagrid showing data?

    - by Edward Tanguay
    This walkthrough says you can create a WPF datagrid in one line but doesn't give a full example. So I created an example using a generic list and connected it to the WPF datagrid, but it doesn't show any data. What do I need to change on the code below to get it to show data in the datagrid? ANSWER: This code works now: XAML: <Window x:Class="TestDatagrid345.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:toolkit="http://schemas.microsoft.com/wpf/2008/toolkit" xmlns:local="clr-namespace:TestDatagrid345" Title="Window1" Height="300" Width="300" Loaded="Window_Loaded"> <StackPanel> <toolkit:DataGrid ItemsSource="{Binding}"/> </StackPanel> </Window> Code Behind: using System.Collections.Generic; using System.Windows; namespace TestDatagrid345 { public partial class Window1 : Window { private List<Customer> _customers = new List<Customer>(); public List<Customer> Customers { get { return _customers; }} public Window1() { InitializeComponent(); } private void Window_Loaded(object sender, RoutedEventArgs e) { DataContext = Customers; Customers.Add(new Customer { FirstName = "Tom", LastName = "Jones" }); Customers.Add(new Customer { FirstName = "Joe", LastName = "Thompson" }); Customers.Add(new Customer { FirstName = "Jill", LastName = "Smith" }); } } }

  • C# Path Ellipsis without Win32 API call revisited

    - by casterle
    I was searching for a way to insert an ellipsis in a C# path, and found an answer here on stackoverflow: http://tinyurl.com/y6rmdfr Using the RTM versions of VS2010 and .Net 4.0, I was unable to get the suggested method to work. I searched the 'Net and found example code that uses the same method, but it failed in the same way. You can see the string I'm trying to shorten in my code below. After calling the MeasureText method, both the input string (OriginalName) and the output string (ellipsisedName) look like this: d:\abcd\efgh\ijkl\mnop\qrst\...\test.txt\0F\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt Two problems: 1) The resulting string is narfed (the path is truncated as expected, but is followed by what looks like a C-style terminating null and a chunk of the original path). 2) My original string is changed to be identical to the output string. Am I doing something wrong? namespace WindowsFormsApplication2 { public partial class Form1 : Form { public Form1() { InitializeComponent(); string OriginalPath = @"d:\abcd\efgh\ijkl\mnop\qrst\uvwx\yzAB\CDEF\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt"; string ellipsisedPath = OriginalPath; Size proposedSize = new Size(label1.Width, label1.Height); TextRenderer.MeasureText(ellipsisedPath, label1.Font, proposedSize, TextFormatFlags.ModifyString | TextFormatFlags.PathEllipsis); } } }

  • View Controller's viewDidLoad method finishing before applicationDidFinishLaunching

    - by mwt
    I'm creating a fairly complex iPhone app using Core Data. Up until now, things have been working fine. As the app has been getting more complex, however, a new problem has come up: the first view controller is finishing its viewDidLoad method before the AppDelegate gets even halfway through its applicationDidFinishLaunching method. The view controller is not the root, which is a tab bar controller. The VC in question is the one for the default selected tab on the tab bar. It's getting instantiated by IB. Nothing like this has occurred before in my experience, and it's throwing off the important initialization I'm doing in the AppDelegate (getting objects from Core Data and preparing them for use) . Furthermore, it's intermittent -- sometimes the delegate does finish first. Has anyone else noticed a difficulty like this? Any sample code that deals with such an issue? I suppose that the answer is to make the VC load the data that the AppDelegate is getting ready only when the AppDelegate sends a message that it's ready. I'm a bit concerned that this is adding something that will just end up biting me in the butt later on.

  • Assert.AreEqual to not fail when comparing an enum and an int

    - by codingbear
    I'm not sure if this is doable, but I will just give a shot. I am calling Assert.AreEqual() method. For the parameters, I'm passing... an enum value which has Int32 as the underlying type because I didn't specify the base type an int (Int32) value Assert fails because it sees that the enum is not int (which is definitely correct). However, is there a way to make this Assert pass when the enum has the correct int value as the 2nd parameter? I can cast the enum to int and have it a quick fix, but it's really ugly. I was expecting some kind of overriding a method that Assert uses to compare 2 different objects and implicitly make that enum type look like an int. However, I wasn't successful at finding any hint/answer around that so far. Someone suggested to create a type converter and use the TypeConverterAttribute to get around. If this works for sure and is the only way to do it, I would; however, it does seem a lot of unnecessary work.

  • Sub Menu Rollover Pop up Not Showing

    - by Stradigos
    Hello everyone, hopefully this will be an easy answer for some of you CSS veterans out there. I'm developing a site for a client. For readability, I'll just give you a link to the website and the css page in question. HTML CSS I'm trying to make a sub menu pop up to the right of the main menu when you scroll over "Star Quartz Grout." My current CSS obviously isn't correct though, and I could use some guidance. ul#subNav {display: none; width: 134px; } li:hover ul#subNav, li.over ul#subNav {display: inline-block; position: absolute; top: 0px; left: 134px; } My guess is that it's working but it's hidden behind the rest of the page. I could be wrong though. It's kind of hard to confirm, even with Chrome's "Inspect Element" (very nice thing btw). It's probably some dumb mistake. Anyway, thanks in advance. I'm a bit of a CSS novice.

  • How to get stack trace information for logging in production when using the GAC

    - by Jonathan Parker
    I would like to get stack trace (file name and line number) information for logging exceptions etc. in a production environment. The DLLs are installed in the GAC. Is there any way to do this? This article says about putting PDB files in the GAC: You can spot these easily because they will say you need to copy the debug symbols (.pdb file) to the GAC. In and of itself, that will not work. I know this article refers to debugging with VS but I thought it might apply to logging the stacktrace also. I've followed the instructions for the answer to this question except for unchecking Optimize code which they said was optional. I copied the dlls and pdbs into the GAC but I'm still not getting the stack trace information. Here's what I get in the log file for the stack trace: OnAuthenticate at offset 161 in file:line:column <filename unknown>:0:0 ValidateUser at offset 427 in file:line:column <filename unknown>:0:0 LogException at offset 218 in file:line:column <filename unknown>:0:0 I'm using NLog. My NLog layout is: layout="${date:format=s}|${level}|${callsite}|${identity}|${message}|${stacktrace:format=Raw}" ${stacktrace:format=Raw} being the relevant part.

  • Static Data Structures on Embedded Devices (Android in particular)

    - by Mark
    I've started working on some Android applications and have a question regarding how people normally deal with situations where you have a static data set and have an application where that data is needed in memory as one of the standard java collections or as an array. In my current specific issue i have a spreadsheet with some pre-calculated data. It consists of ~100 rows and 3 columns. 1 Column is a string, 1 column is a float, 1 column is an integer. I need access to this data as an array in java. It seems like i could: 1) Encode in XML - This would be cpu intensive to decode in my experience. 2) build into SQLite database - seems like a lot of overhead for static access to data i only need array style access to in ram. 3) Build into binary blob and read in. (never done this in java, i miss void *) 4) Build a python script to take the CSV version of my data and spit out a java function that adds the values to my desired structure with hard coded values. 5) Store a string array via androids resource mechanism and compute the other 2 columns on application load. In my case the computation would require a lot of calls to Math.log, Math.pow and Math.floor which i'd rather not have to do for load time and battery usage reasons. I mostly work in low power embedded applications in C and as such #4 is what i'm used to doing in these situations. It just seems like it should be far easier to gain access to static data structures in java/android. Perhaps I'm just being too battery usage conscious and in my single case i imagine the answer is that it doesn't matter much, but if every application took that stance it could begin to matter. What approaches do people usually take in this situation? Anything I missed?

  • Wordpress displays posts of category ID

    - by Miker
    Can't seem to find the right answer for what I thought would be trivial. I have some categories arranged like this... Parent Category 1 - Child Category 1 - Child Category 2 - Child Category 3 ...and I have some posts that are in Child Category 2. I want my page to display all posts from the category I am currently in. This is what I am doing right now: <?php query_posts('cat=2&showposts=10'); if (have_posts()) : while (have_posts()) : the_post(); ?> <div class="timeline"> <h3><?php the_title(); ?></h3> <?php the_content();?> <?php endwhile; else: ?> <?php _e('No Posts Sorry.'); ?> <?php endif; ?> </div> As you can see I am having to manually specify the category (cat=2), but instead I want it to automatically detect the category I am already in and display the posts (that way if I'm in a different category it will display those posts). Any suggestions? Thanks in advance. (SO Community = Awesome Sauce).

  • Database warehouse design: fact tables and dimension tables

    - by morpheous
    I am building a poor man's data warehouse using a RDBMS. I have identified the key 'attributes' to be recorded as: sex (true/false) demographic classification (A, B, C etc) place of birth date of birth weight (recorded daily): The fact that is being recorded My requirements are to be able to run 'OLAP' queries that allow me to: 'slice and dice' 'drill up/down' the data and generally, be able to view the data from different perspectives After reading up on this topic area, the general consensus seems to be that this is best implemented using dimension tables rather than normalized tables. Assuming that this assertion is true (i.e. the solution is best implemented using fact and dimension tables), I would like to seek some help in the design of these tables. 'Natural' (or obvious) dimensions are: Date dimension Geographical location Which have hierarchical attributes. However, I am struggling with how to model the following fields: sex (true/false) demographic classification (A, B, C etc) The reason I am struggling with these fields is that: They have no obvious hierarchical attributes which will aid aggregation (AFAIA) - which suggest they should be in a fact table They are mostly static or very rarely change - which suggests they should be in a dimension table. Maybe the heuristic I am using above is too crude? I will give some examples on the type of analysis I would like to carryout on the data warehouse - hopefully that will clarify things further. I would like to aggregate and analyze the data by sex and demographic classification - e.g. answer questions like: How does male and female weights compare across different demographic classifications? Which demographic classification (male AND female), show the most increase in weight this quarter. etc. Can anyone clarify whether sex and demographic classification are part of the fact table, or whether they are (as I suspect) dimension tables.? Also assuming they are dimension tables, could someone elaborate on the table structures (i.e. the fields)? The 'obvious' schema: CREATE TABLE sex_type (is_male int); CREATE TABLE demographic_category (id int, name varchar(4)); may not be the correct one.

  • Java RMI InitialContext: Equivalent of LocateRegistry.createRegistry(int) ?

    - by bguiz
    I am trying to some pretty basic RMI: // Context namingContext = new InitialContext(); Registry reg = LocateRegistry.createRegistry(9999); for ( int i = 0; i < objs.length; i++ ) { int id = objs[i].getID(); // namingContext.bind( "rmi:CustomObj" + id , objs[i] ); reg.bind( "CustomObj" + id , objs[i] ); } That works without a hitch, but for future purposes, I need to use InitialContext. Context namingContext = new InitialContext(); for ( int i = 0; i < objs.length; i++ ) { int id = objs[i].getID(); namingContext.bind( "rmi:CustomObj" + id , objs[i] ); } But I cannot get this to work. I have started rmiregistry from the command line. Is there an equivalent of LocateRegistry.createRegistry(int)? Or some other way to start the RMI registry / registry used by InitialContext from inside my class?

  • why does text from socket server erase previously written text?

    - by mix
    This is strange enough I'm not sure how to search for an answer. I have a program in Python that communicates via TCP/IP sockets to a telnet-based server. If I telnet in manually and type commands like this: SET MDI G0 X0 Y0 the server will spit back a line like this: SET MDI ACK Pretty standard stuff. Here's the weird part. If, in my code, I precede my printing of each of these lines with some text, the returned line erases what I'm trying to print before it. So for example, if I write the code so it should look like this: SENT: SET MDI G0 X0 Y0 READ: SET MDI ACK What I get instead is: SENT: SET MDI G0 X0 Y0 SET MDI ACK Now, if I make the "READ: " text a bit longer, I can get a better idea of what's happening. Let's say I change READ: to 12345678901234567890, so that it should read as: 12345678901234567890: SET MDI ACK What I get instead is: SET MDI ACK234567890: So it seems like whatever text I'm getting back from the server is somehow deleting what I'm trying to precede it with. I tried saving all of my saved lines in a list, and then printing them out at the end, but it does exactly the same thing. Any ideas on what's going on, or even on how to debug this? Is there a way to get Python to show me any hidden chars in a string, for example? thx!

  • Where can I find free and open data?

    - by kitsune
    Sooner or later, coders will feel the need to have access to "open data" in one of their projects, from knowing a city's zip to a more obscure information such as the axial tilt of Pluto. I know data.un.org which offers access to the UN's extensive array of databases that deal with human development and other socio-economic issues. The other usual suspects are NASA and the USGS for planetary data. There's an article at readwriteweb with more links. infochimps.org seems to stand out. Personally, I need to find historic commodity prices, stock values and other financial data. All these data sets seem to cost money however. Clarification To clarify, I'm interested in all kinds of open data, because sooner or later, I know I will be in a situation where I could need it. I will try to edit this answer and include the suggestions in a structured manners. A link for financial data was hidden in that readwriteweb article, doh! It's called opentick.com. Looks good so far! Update I stumbled over semantic data in another question of mine on here. There is opencyc ('the world's largest and most complete general knowledge base and commonsense reasoning engine'). A project called UMBEL provides a light-weight, distilled version of opencyc. Umbel has semantic data in rdf/owl/skos n3 syntax. The Worldbank also released a very nice API. It offers data from the last 50 years for about 200 countries

  • NHibernate HiLo generation and SQL 2005/8 Schemas

    - by Kirk Clawson
    I have an issue on my hands that I've spent several days searching for an answer to no avail... We're using HiLo Id generation, and everything seems to be working fine, as long as the entity table is in the same schema as the hibernate_unique_key table. The table structure is pretty simple. I have my hi value table in the db as dbo.hibernate_unique_key. Several entity table are also in the dbo schema, and they work without issue. Then we have tables under the "Contact" schema (such as Contact.Person and Contact.Address). In the Person Mapping file: <class name="Person" table="Person" schema="Contact"> <id name="Id" unsaved-value="0"> <generator class="hilo"> <param name="max_lo">100</param> </generator> </id> ... When I try to insert a Person entity, I get an error of "Invalid object name 'Contact.hibernate_unique_key'. That error is certainly clear enough. So I add: <param name="schema">dbo</param> to my mapping file/generator element. Now, when the SessionFactory is built, I get a "An item with the same key has already been added." error. So now I'm a bit stuck. I can't leave the HiLo generator without a schema, because it picks up the schema from the Class, and I can't specify the schema because it's already been added (presumably because it's my "default_schema" as identified in my XML cfg file). Am I completely hosed here? Must I either A) Keep all my tables in the dbo schema or B) Create a separate HiLo Key table for each unique schema in the DB? Neither of those scenarios is particularly palatable for my application, so I'm hoping that I can "fix" my mapping files to address this issue.

  • Apache Axis2 1.5.1 and NTLM Authentication

    I've browsed all of the discussions here on StackOverflow regarding NTLM and Java, and I can't seem to find the answer. I'll try and be much more specific. Here's some code that returns a client stub that (I hope) is configured for NTLM authentication: ServiceStub getService() { try { ServiceStub stub = new ServiceStub( "http://myserver/some/path/to/webservices.asmx"); // this service is hosted on IIS List<String> ntlmPreferences = new ArrayList<String>(1); ntlmPreferences.add(HttpTransportProperties.Authenticator.NTLM); HttpTransportProperties.Authenticator ntlmAuthenticator = new HttpTransportProperties.Authenticator(); ntlmAuthenticator.setPreemptiveAuthentication(true); ntlmAuthenticator.setAuthSchemes(ntlmPreferences); ntlmAuthenticator.setUsername("me"); ntlmAuthenticator.setHost("localhost"); ntlmAuthenticator.setDomain("mydomain"); Options options = stub._getServiceClient().getOptions(); options.setProperty(HTTPConstants.AUTHENTICATE, ntlmAuthenticator); options.setProperty(HTTPConstants.REUSE_HTTP_CLIENT, "true"); stub._getServiceClient().setOptions(options); return stub; } catch (AxisFault e) { e.printStackTrace(); } return null; } This returns a valid SerivceStub object. When I try to invoke a call on the stub, I see the following in my log: Jun 9, 2010 12:12:22 PM org.apache.commons.httpclient.auth.AuthChallengeProcessor selectAuthScheme INFO: NTLM authentication scheme selected Jun 9, 2010 12:12:22 PM org.apache.commons.httpclient.HttpMethodDirector authenticate SEVERE: Credentials cannot be used for NTLM authentication: org.apache.commons.httpclient.UsernamePasswordCredentials Does anyone have a solution to this issue?

  • shortest digest of a string

    - by meta
    [Description] Given a string of char type, find a shortest digest, which is defined as: a shortest sub-string which contains all the characters in the original string. [Example] A = "aaabedacd" B = "bedac" is the answer. [My solution] Define an integer table with 256 elements, which is used to record the occurring times for each kind of character in the current sub-string. Scan the whole string, statistic the total kinds of character in the given string by using the above table. Use two pointers, start, end, which are initially pointing to the start and (start + 1) of the given string. The current kinds of character is 1. Expand sub-string[start, end) at the end until it contains all kinds of character. Update the shortest digest if possible. Contract sub-string[start, end] at the start by one character each time, try to restore its digest property if necessary by step 4. The time cost is O(n), and the extra space cost is constant. Any better solution without extra space?

  • How to group strings by prefix

    - by namenlos
    I am writing a Winform UI in which the user must select a single customer. (For reasons beyond my control I am limited to a UI that uses dropdown lists, text fields, checkboxes, radiobuttons only -i.e. no fancy special UI controls) The situation There are a lot of customers (a thousand for example) If i put all the customers in a single dropdown there's no way it will be easy for a customer to even see all the customers. Also the it will take too long to retireve all the customers from the DB to populate the dropdown My thought is to have two combo box, the first lists groups of the customers by their last name something like a phone book "Aa-Ac", "Ad-Ade", "Adf-B", when selecting the first combo box, it scope the second one to a managable set customer names (no more than for example 40 names) The question I need a reasonable way of grouping their names such that it will be clear to customer which group contains the name. I.e. given a group of names I need to bucketize then int "Aa-Ac". Comments I don't need to solve the general problem of an immense number of names - we know based on our data that 1000 names is the max our users will encounter. If there are other techniques please do share, but I am interested specifically in an answer to my specific question around how to determine the buckets ("Aa-Ac", etc.)

  • C# Regex - Replace multiple characters at once without overwriting?

    - by Everaldo Aguiar
    Hello guys, I'm implementing a c# program that should automatize a Mono-alphabetic substitution cipher. The functionality i'm working on at the moment is the simplest one: The user will provide a plain text and a cipher alphabet, for example: Plain text(input): THIS IS A TEST Cipher alphabet: A - Y, H - Z, I - K, S - L, E - J, T - Q Cipher Text(output): QZKL KL QJLQ I thought of using regular expressions since I've been programming in perl for a while, but I'm encountering some problems on c#. First I would like to know if someone would have a suggestion for a regular expression that would replace all occurrence of each letter by its corresponding cipher letter (provided by user) at once and without overwriting anything. Example: In this case, user provides plaintext "TEST", and on his cipher alphabet, he wishes to have all his T's replaced with E's, E's replaced with Y and S replaced with J. My first thought was to substitute each occurrence of a letter with an individual character and then replace that character by the cipherletter corresponding to the plaintext letter provided. Using the same example word "TEST", the steps taken by the program to provide an answer would be: 1 - replace T's with (lets say) @ 2 - replace E's with # 3 - replace S's with & 4 - Replace @ with E, # with Y, & with j 5 - Output = EYJE This solution doesn't seem to work for large texts. I would like to know if anyone can think of a single regular expression that would allow me to replace each letter in a given text by its corresponding letter in a 26-letter cipher alphabet without the need of splitting the task in an intermediate step as I mentioned. If it helps visualize the process, this is a print screen of my GUI for the program: http://img43.imageshack.us/img43/2118/11618743.jpg

  • LINQ 2 SQL: Partial Classes

    - by Refracted Paladin
    I need to set the ConnectionString for my DataContext's based on an AppSetting. I am trying to do this by creating a Partial Class for each DataContext. The below is what I have so far and I am wondering if I am overlooking something? Specifically, am I dealing with my DataContext's correctly(disposing, staleness, etc)? Doing it this way will I have issues with Updates and Inserts? Is the file BLLAspnetdb.cs useful or neccessary in the least or should all of that be in the generated partial class AspnetdbDataContext file? In short, is this an acceptable structure or will this cause me issues as I elaborate it? dbml File Name = Aspnetdb.dbml Partial Class File Name = Aspnetdb.cs partial class AspnetdbDataContext { public static bool IsDisconnectedUser { get { return Convert.ToBoolean(ConfigurationManager.AppSettings["IsDisconnectedUser"]) == true; } } public static AspnetdbDataContext New { get { var cs = IsDisconnectedUser ? Settings.Default.Central_aspnetdbConnectionString : Settings.Default.aspnetdbConnectionString; return new AspnetdbDataContext(cs); } } } My Created File Name = BLLAspnetdb.cs public class BLLAspnetdb { public static IList WorkerList(Guid userID) { var DB = AspnetdbDataContext.New; var workers = from user in DB.tblDemographics where user.UserID == userID select new { user.FirstName, user.LastName, user.Phone }; IList theWorkers = workers.ToList(); return theWorkers; } public static String NurseName(Guid? userID) { var DB = AspnetdbDataContext.New; var nurseName = from demographic in DB.tblDemographics where demographic.UserID == userID select demographic.FirstName +" " + demographic.LastName; return nurseName.SingleOrDefault(); } public static String SocialWorkerName(Guid? userID) { var DB = AspnetdbDataContext.New; var swName = from demographic in DB.tblDemographics where demographic.UserID == userID select demographic.FirstName + " " + demographic.LastName; return swName.SingleOrDefault(); } } see this previous question and the accepted answer for background on how I got to here... switch-connectionstrings-between-local-and-remote-with-linq-to-sql
