  • WCF Ria Services For Real

    In my previous post I discussed creating the database and tables for the Silverlight HVP configuration data.  All that was great, and worked just dandy until it was time to get the data from the database server to the application running on the client. But, I thought, How hard can it be?  Ive done a few mini-tutorials should be straight-forward And it was sorta. Getting Going The steps are pretty straight forward: Create an entity data model that corresponds to the tables ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • WebForms vs MVC (again)

    There's a new video up on www.asp.net which aims to help developers pick between ASP.NET WebForms and ASP.NET MVC. The video boils down to 5 benefits per technology which Microsoft thinks you should consider. Let's go over the points, shall we? First, ASP.NET WebForms: 1 - Familiar control and event base programming model The claim here is that the ASP.NET model is comfortable for WinForm programmers (thankfully this unbiased analysis left out who it's more familiar for). This is largely...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

  • Which .NET performance and/or memory profilers will allow me to profile a DLL?

    - by Eric
    I write a lot of .NET based plug-ins for other programs which are usually compiled as a DLL which is up to the native application to start up. I've been using Equatec's profiler, which works great, but now would like something with more features, including the ability to profile memory usage. I tried out Red Gate's Ant Profiler, but as far as I can see there is no way to profile a DLL. The only option is to profile an EXE. So my question is what other profiling tools are available that will allow me to profile a single library DLL rather than an EXE. I'm assuming this would require injecting profile code into the library as Equatec does?

  • FPDF Page Break Question

    - by Michael
    I am using PHP and FPDF to generate a PDF with a list of items. My problem is if the item list goes on to a second or third page, I want to keep the Item Name, Quantity and Description together. Right now, it will go to a second page, but it may split up all of the details for a particular item. PLEASE HELP! <?php require_once('auth.php'); require_once('config.php'); require_once('connect.php'); $sqlitems="SELECT * FROM $tbl_items WHERE username = '" . $_SESSION['SESS_LOGIN'] . "'"; $resultitems=mysql_query($sqlitems); require_once('pdf/fpdf.php'); require_once('pdf/fpdi.php'); $pdf =& new FPDI(); $pdf->AddPage('P', 'Letter'); $pdf->setSourceFile('pdf/files/healthform/meds.pdf'); $tplIdx = $pdf->importPage(1); $pdf->useTemplate($tplIdx); $pdf->SetAutoPageBreak(on, 30); $pdf->SetTextColor(0,0,0); $pdf->Ln(10); while($rowsitems=mysql_fetch_array($resultitems)){ $pdf->SetFont('Arial','B',10); $pdf->Cell(50,4,'Item Name:',0,0,'L'); $pdf->SetFont(''); $pdf->Cell(100,4,$rowsitems['itemname'],0,0,'L'); $pdf->SetFont('Arial','B',10); $pdf->Cell(50,4,'Quantity:',0,0,'L'); $pdf->SetFont(''); $pdf->Cell(140,4,$rowsitems['itemqty'],0,1,'L'); $pdf->SetFont('Arial','B'); $pdf->Cell(50,4,'Description:',0,0,'L'); $pdf->SetFont(''); $pdf->Cell(140,4,$rowsitems['itemdesc'],0,1,'L'); } $pdf->Output('Items.pdf', 'I'); ?>

  • Convert C# unit test names to English (testdox style)

    - by Igor Zevaka
    I have a whole bunch of unit tests written in MbUnit and I would like to generate plain English sentences from test names. The concept is introduced here: http://dannorth.net/introducing-bdd This is from the article: public class CustomerLookupTest extends TestCase { testFindsCustomerById() { ... } testFailsForDuplicateCustomers() { ... } ... } renders something like this: CustomerLookup - finds customer by id - fails for duplicate customers - ... Unfortunately the tool quoted in the above article (testdox) is Java based. Is there one for .NET? Sounds like this would be something pretty simple to write, but I simply don't have the bandwidth and want to use something already written.

  • running asp.net 3.5 and asp.net 2.0 in same site

    - by cori
    We're running ASP.Net 2.0 on our corporate web site, and I'd like to get it up to ASP.Net 3.5 as smoothly as possible. The project/solution architecture in VS 2005 is an ASP.Net 2.0 web project and an .Net 2.0 data access layer project which is used by the site code. Upon opening the projects in a new VS 2008 solution they seemed to be converted to .Net 3.5 with a minimum of fuss - they built correctly out of the box, deployed successfully, and seem to work just fine, which is exactly as I would expect given that .Net 2.0 and 3.5 share a common runtime. The major difference after the conversion is that the web.config file's referenced dlls are now the 3.5 versions. What I would like to do is to update the site piecemeal; as I make modifications to a given page send the 3.5 verson of that page over to our webserver and not update the whole site at once. In testing on our dev box this approach seems to be working fine - the site code is interacting with the .Net 3.5 data access layer without difficulty, a handful of pages are running 3.5 page-behind code (by this I mean that they're running assemblies built in VS 2008 - the site is using single-page assemblies for code behind), the 3.5 web.config is in place, and the bulk of the site is running code-behind assemblies built in VS2005. Everything looks great. Which makes me worried that I'm missing something. Is this architecture workable, or is there a problem lying is wait for m that I haven't considered?

  • One template specialization for multiple classes

    - by peper0
    Let's assume we have a template function "foo": template<class T> void foo(T arg) { ... } I can make specialization for some particular type, e.g. template<> void foo(int arg) { ... } If I wanted to use the same specialization for all builtin numeric types (int, float, double etc.) I would write those lines many times. I know that body can be thrown out to another function and just call of this is to be made in every specialization's body, however it would be nicer if i could avoid writting this "void foo(..." for every type. Is there any possibility to tell the compiler that I want to use this specialization for all this types?

  • algorithm q: Fuzzy matching of structured data

    - by user86432
    I have a fairly small corpus of structured records sitting in a database. Given a tiny fraction of the information contained in a single record, submitted via a web form (so structured in the same way as the table schema), (let us call it the test record) I need to quickly draw up a list of the records that are the most likely matches for the test record, as well as provide a confidence estimate of how closely the search terms match a record. The primary purpose of this search is to discover whether someone is attempting to input a record that is duplicate to one in the corpus. There is a reasonable chance that the test record will be a dupe, and a reasonable chance the test record will not be a dupe. The records are about 12000 bytes wide and the total count of records is about 150,000. There are 110 columns in the table schema and 95% of searches will be on the top 5% most commonly searched columns. The data is stuff like names, addresses, telephone numbers, and other industry specific numbers. In both the corpus and the test record it is entered by hand and is semistructured within an individual field. You might at first blush say "weight the columns by hand and match word tokens within them", but it's not so easy. I thought so too: if I get a telephone number I thought that would indicate a perfect match. The problem is that there isn't a single field in the form whose token frequency does not vary by orders of magnitude. A telephone number might appear 100 times in the corpus or 1 time in the corpus. The same goes for any other field. This makes weighting at the field level impractical. I need a more fine-grained approach to get decent matching. My initial plan was to create a hash of hashes, top level being the fieldname. Then I would select all of the information from the corpus for a given field, attempt to clean up the data contained in it, and tokenize the sanitized data, hashing the tokens at the second level, with the tokens as keys and frequency as value. I would use the frequency count as a weight: the higher the frequency of a token in the reference corpus, the less weight I attach to that token if it is found in the test record. My first question is for the statisticians in the room: how would I use the frequency as a weight? Is there a precise mathematical relationship between n, the number of records, f(t), the frequency with which a token t appeared in the corpus, the probability o that a record is an original and not a duplicate, and the probability p that the test record is really a record x given the test and x contain the same t in the same field? How about the relationship for multiple token matches across multiple fields? Since I sincerely doubt that there is, is there anything that gets me close but is better than a completely arbitrary hack full of magic factors? Barring that, has anyone got a way to do this? I'm especially keen on other suggestions that do not involve maintaining another table in the database, such as a token frequency lookup table :). This is my first post on StackOverflow, thanks in advance for any replies you may see fit to give.

  • Sending items in a LINQ sequence to a method that returns void

    - by generalt
    Hello all. Often while I'm dealing with LINQ sequences, I want to send each item to a method returning void, avoiding a foreach loop. However, I haven't found an elegant way to do this. Today, I wrote the following code: private StreamWriter _sw; private void streamToFile(List<ErrorEntry> errors) { if (_sw == null) { _sw = new StreamWriter(Path.Combine (Path.GetDirectoryName(_targetDatabasePath), "errors.txt")); } Func<ErrorEntry, bool> writeSelector = (e) => { _sw.WriteLine(getTabDelimititedLine(e)); return true; }; errors.Select(writeSelector); _sw.Flush(); } As you can see, I write a lambda function that just returns true, and I realize that the Select method will return a sequence of booleans- I'll just ignore that sequence. However, this seems a little bit noobish and jank. Is there any elegant way to do this? Or am I just misapplying LINQ? Thanks.

  • sql exception when transferring project from usb to c:\

    - by jello
    I'm working on a C# windows program with Visual Studio 2008. Usually, I work from school, directly on my usb drive. But when I copy the folder on my hard drive at home, an sql exception is unhandled whenever I try to write to the database. it is unhandled at the conn.Open(); line. here's the exception unhandled Database 'L:\system\project\the_project\the_project\bin\Debug\PatientMonitoringDatabase.mdf' already exists. Choose a different database name. Cannot attach the file 'C:\Documents and Settings\Administrator\My Documents\system\project\the_project\the_project\bin\Debug\PatientMonitoringDatabase.mdf' as database 'PatientMonitoringDatabase'. it's weird, because my connection string says |DataDirectory|, so it should work on any drive... here's my connection string: string connStr = "Data Source=.\\SQLEXPRESS;AttachDbFilename=|DataDirectory|\\PatientMonitoringDatabase.mdf; " + "Initial Catalog=PatientMonitoringDatabase; " + "Integrated Security=True"; Someone told me to: Connect to localhost with SQL Server Management Studio Express, and remove/detach the existing PatientMonitoringDatabase database. Whether it's a persistent database or only active within a running application, you can't have 2 databases with the same name at the same time attached to a SQL Server instance. So I did that, and now it gives me: Directory lookup for the file "C:\Documents and Settings\Administrator\My Documents\system\project\the_project\the_project\bin\Debug\PatientMonitoringDatabase.mdf" failed with the operating system error 5(Access is denied.). Cannot attach the file 'C:\Documents and Settings\Administrator\My Documents\system\project\the_project\the_project\bin\Debug\PatientMonitoringDatabase.mdf' as database 'PatientMonitoringDatabase' I checked the files' properties, and I have allow for everyone. Does anyone know what's going on here?

  • How do you create a dropdownlist from an enum in ASP.NET MVC?

    - by Kevin Pang
    I'm trying to use the Html.DropDownList extension method but can't figure out how to use it with an enumeration. Let's say I have an enumeration like this: public enum ItemTypes { Movie = 1, Game = 2, Book = 3 } How do I go about creating a dropdown with these values using the Html.DropDownList extension method? Or is my best bet to simply create a for loop and create the html elements manually?

  • Scheme implementations - what does it mean?

    - by JDelage
    Hi, I'm a beginning student in CS, and my classes are mostly in Java. I'm currently going through "Little Schemer" as a self study, and in the process of finding out how to do that I have found numerous references to "implementations" of Scheme. My question is, what are implementations? Are they sub-dialects of Scheme, or is that something else (DrScheme seem to allow for different "flavors" of the language)? Is it just the name given to any given ecosystem incorporating an IDE, interpreter, interactive tool and the like? Do all other languages (e.g., Java) also have a variety of "implementations", or is it something reserved to "open" languages? Thank you, Joss Delage

  • In .NET, How to obtain the target of a symbolic link (or Reparse Point)?

    - by Cheeso
    In .NET, I think I can determine if a file is a symbolic link by calling System.IO.File.GetAttributes(), and checking for the ReparsePoint bit. like so: var a = System.IO.File.GetAttributes(fileName); if ((a & FileAttributes.ReparsePoint) != 0) { // it's a symlink } How can I obtain the target of the symbolic link, in this case? ps: I know how to create a symbolic link. It requires P/Invoke: [Interop.DllImport("kernel32.dll", EntryPoint="CreateSymbolicLinkW", CharSet=Interop.CharSet.Unicode)] public static extern int CreateSymbolicLink(string lpSymlinkFileName, string lpTargetFileName, int dwFlags);

  • How can I prevent Rails from "pluralizing" a column name?

    - by Mike
    I'm using dwilkie's foreigner plugin for rails. I have a table creation statement that looks like: create_table "agents_games", :force => true, :id => false do |t| t.references :agents, :column => :agent_id, :foreign_key => true, :null => false t.references :games, :column => :game_id, :foreign_key => true, :null => false end However, this generates the following SQL: [4;35;1mSQL (2.7ms)[0m [0mCREATE TABLE "agents_games" ("agents_id" integer NOT NULL, "games_id" integer NOT NULL) [0m I want the columns to be called agent_id and game_id - not agents_id and agent_id. How can I prevent Rails from pluralizing the columns? I tried the following in my enviornment.rb file, which didn't help: ActiveSupport::Inflector.inflections do |inflect| inflect.uncountable "agent_id", "game_id" end

  • how to hack this php class for parse ZIP file in random or specific order

    - by Jesse
    My English is poor so I will make it short. Right now, I have imzip.zip which has three txt files: a.txt b.txt c.txt When I try to load imzip.zip using: http://pastebin.com/m1d974990 It loads the files alphabetically. In this case: a.txt b.txt c.txt However, I would like to be able to have the class load on different variables such as by size, date or simply random. The problem is I have no idea how I would go about modifying the class to fit my needs. I would really appreciate your help! :D

  • 3rd Party Document Management Service

    - by Element
    I am developing an asp.net application that requires users to upload/view various documents. Rather then reinvent the wheel I was thinking about using a 3rd party service like Scribd to handle these documents and integrate it into my app via their API; I really like their ipaper viewer too. My concern is some of these documents will be sensitive data. Even though Scribd's FAQ says they are equipped to handle sensitive information, I am a little hesitant to trust an unpaid service that lacks an SLA. Has anyone used Scribd successfully for a similar task? Or can anyone recommend a better document management service?

  • update jquery validation plugin dateISO javascript

    Right now...the dateISO method is as follows: dateISO: function(value, element) { return this.optional(element) || /^\d{4}[\/-]\d{1,2}[\/-]\d{1,2}$/.test(value); }, but ive noticed that when a user enters something like 1991-99-99 it sees it as a "valid date" when it obviously is not. How would i change this code to have it check if the month is 01-12 and the date is 1-31?

  • Property Scope (Iphone)

    - by Hank
    Hello All. I am having trouble accessing a declared property and I think I am missing something fundamental about the nature of properties and perhaps view controllers. Here's what I'm doing so far: declaring a property "myPhone" in a root view controller called RootViewController. grabbing a phone number from a modally presented people picker setting "myPhone" to the value from the people picker (from within shouldContinueAfterSelectingPerson of ABPeoplePickerNavigationController) trying to access "myPhone" from another modally presented view controller "myPhone" continues to NSLog to null despite trying every permutation of self.myPhone, super, RootViewController, etc. to try and access the value I set. What am I missing?

  • Any good method for mounting Hadoop HDFS from another system?

    - by Beel
    I want to mount the Cloudera Hadoop as a Linux file system over the LAN. As a setup, I already have the hadoop cluster running on a set of Ubuntu machines. But now I need to be able to use it as a normal file system from a Fedora system over the LAN. I tried FUSe but two things: 1. Cloudera says FUSE loses data (click here for that comment by a Cloudera employee on the official Cloudera support site) 2. I've had no success making it work the way we want As a point of clarification, I am using Hadoop ONLY for the file system, not for its other capabilities.

  • notepad sql Unicode and Non Unicode

    - by RBrattas
    Hi, I have a Microsoft Notepad flate file with data and Vertical Bar as column delimiter. I get following message: cannot convert between unicode and non-unicode string data types It seems it is my nvarchar(max) that creates my problem. I changed to varchar(max); but still the same problem. How do I insert my flate file into my SQL Server 2005? And in the SQL Server 2005 import and export wizard the flate file source advanced tab the OutputColumnWith is 50. Will that say my flate file column is max 50? I hope not because my column is more then 50... Thank you, Rune

  • Create an alias in Windows XP

    - by Lord Torgamus
    Back in school, I used to have a .login file along the lines of alias ll = ls -l alias dir = ls -Fhl alias web = cd ~/public/public_www/development ... I'd like to do that sort of thing with my XP box here at work, but most of the resources I've found online seem fairly complicated and heavy-duty. Is there a way to do this that doesn't involve mucking about in the registry or running a large batch file? EDIT: My original reason for asking this was that I only need the command line for one command in one specific folder, and I wanted to be able to get to that folder quickly when I launched the command line. But the accepted answer for this question is so good that I decided to ask about my original issue as a separate question here.
