• How to use Dependency Injection with ASP.NET

  - by Schneider

  I am trying to work out a way to use Dependency Injection with ASP.NET controls. I have got lots of controls that create repositories directly, and use those to access and bind to data etc. I am looking for a pattern where I can pass repositories to the controls externally (IoC), so my controls remain unaware of how repositories are constructed and where they come from etc. I would prefer not to have a dependency on the IoC container from my controls, therefore I just want to be able to construct the controls with constructor or property injection. (And just to complicate things, these controls are being constructed and placed on the page by a CMS at runtime!) Any thoughts?

• Is this sufficient to prevent query injection while using SQL Server?

  - by Derek Adair

  Hi, I have recently taken on a project in which I need to integrate with PHP/SQL Server. I am looking for the quickest and easiest function to prevent SQL injection on SQL Server as I prefer MySQL and do not anticipate many more SQL Server related projects. Is this function sufficient? $someVal = mssql_escape($_POST['someVal']); $query = "INSERT INTO tblName SET field = $someVal"; mssql_execute($query); function mssql_escape($str) { return str_replace("'", "''", $str); } If not, what additional steps should I take?

• What's a good way to copy files from a PC to a Windows Mobile device?

  - by MusiGenesis

  I have a C# application running on a server, and it needs to copy files out to multiple Windows Mobile 5.0 devices. These devices are connected to the network directly via Ethernet-enabled cradles (so they are not connected to a PC via ActiveSync). What different options do I have for doing this? I know RAPI can do this, but I'm not sure if it can copy something directly over the network like this. Also, I know RAPI uses ActiveSync DLLs and thus requires ActiveSync to be installed, and we would prefer to avoid doing this if possible. Is WMI a possibility? Can we use ordinary File.IO if we can somehow get the IP address of each device? Code samples or general knowledge would be most welcome.

• Progressive Enhancement with box-shadow

  - by toby

  I would like to use WebKit's box-shadow css property for a little drop-down. The code would look like: .drop_down{ -webkit-box-shadow: 1px 1px 4px #888; box-shadow: 1px 1px 4px #888; } However, for browsers that do not have this capability, I would like to use borders to approximate this drop shadow, like so: .drop_down{ border-top: 1px solid #bbb; border-left: 1px solid #bbb; border-right: 2px solid #bbb; border-bottom: 2px solid #bbb; } The problem is, I don't want the border-based shadow to show up for the browsers that DO support box-shadow. I would like to avoid browser sniffing because I assume it's hard to cover all the cases. What is the simplest way to do this? I prefer a javascript-less solution, but I will consider simple javascript-based ones too.

• C/C++/Assembly Programatically detect if hyper-threading is active on Windows, Mac and Linux

  - by HTASSCPP

  I can already correctly detect the number of logical processors correctly on all three of these platforms. To be able to detect the number of physical processors/cores correctly I'll have to detect if hyperthreading is supported AND active (or enabled if you prefer) and if so divide the number of logical processors by 2 to determine the number of physical processors. Perphaps I should provide an example: A quad core Intel CPU's with hyperthreading enabled has 4 physical cores, yet 8 logical processors (hyperthreading creates 4 more logical processors). So my current function would detect 8 instead of the desired 4. My question therefore is if there is a way to detect whether hyperthreading is supported AND ENABLED?

• Substituting Java for Groovy Little By Little

  - by yar

  I have been checking out Groovy a bit and I feel that moving a Java program to Groovy little by little -- grabbing a class and making it a Groovy class, then converting the method guts a bit at a time -- might be a relatively sane way to take advantage of some of the Groovy language features. I would also do new classes in Groovy. Questions: Is this a reasonable way to convert? Can I keep all of my public methods and and fields in Java? Groovy is "just" a superset, right? What kinds of things would you not do in Groovy, but prefer Java instead?

• Easy way to Populate a Dictionary<string,List<string>>

  - by zion

  Greetings Guru's, my objective is to create a Dictionary of Lists, does a simpler technique exist? I prefer the List(t) to IEnumerable(t) which is why I chose the Dictionary of Lists over Ilookup or IGrouping. The code works but it seems like a messy way of doing things. string[] files = Directory.GetFiles (@"C:\test"); Dictionary<string,List<string>> DataX = new Dictionary<string,List<string>>(); foreach (var group in files.GroupBy (file => Path.GetExtension (file))) { DataX.Add (group.Key, group.ToList()); }

• Low noise sites to keep track of news related to computers & programming?

  - by Sridhar Ratnakumar

  I am aware of sites like Slashdot and Ars Technica. Unfortunately they publish way too many articles per day. Ars Technical: 100 posts per week Slashdot: 179 posts per week And I prefer not to waste my attention over reading about 180 posts (even if I were to skim) every week. Is there a site that provides only important news - excluding not-so-important news items like top 6 iPad apps that someone is dying to try out (but haven't done yet; still thinks their readers/advertisers care about it)?

• Maven multi-module project with many reports: looking for an example

  - by hstoerr

  Is there an open source project that can serve as a good example on how to use the maven site plugin to generate reports? I would prefer it to consist of many modules, possibly hierarchically structured use as many plugins as possible (surefire, jxr, pmd, findbugs, javadoc, checkstyle, you name it) the reports should be aggregated: if some tests fail you want to have a single page that shows all modules with failing tests, not only a gazillion individual pages to check include enterprisey stuff (WAR, EAR etc), but this is not so important. The idea is to have something where you can gather ideas on how it is done and what is possible.

• Invoking MSYS bash from Windows cmd

  - by daevius

  I'm using GCC on Windows7 (using the TDM's build). I installed MSYS to be able to execute make and compile using makefiles. However, it is tedious to every time start up the MSYS bash shell, navigate to the directory of the project and run make. What I want is to automate this process. I prefer to have a batch file in Windows, or something similar, from which I then invoke the MSYS bash. It should navigate to the directory the batch file resides in and call "make". Is this possible? Can I send commands to MSYS bash from cmd (like navigation / invoking make)? Or can I let the MSYS bash run a "bash script", which sets the commands to be executed much like batch scripts? Thank you. PS: this is something similar as this question: http://stackoverflow.com/questions/2546757/executing-msys-from-cmd-exe-with-arguments

• iPhone OS: implementing your own achievements, how do I do it?

  - by nickthedude

  I'm working on a game where really the only game part is (at least right now) that the user can unlock achievements as she does various things throughout the game. I have a database that can keep track of certain user actions and record how many times a user does something but I'm having trouble figuring out the best way to architect the app so that I have to do the least amount of work. Kind of suck with the timing because gamecenter is not ready and it seems like openfeint is changing gears, but maybe I'm wrong. I'd prefer to do everything "in house" if it is not too ridiculous. looking for suggestions. Thanks, Nick

• When should I use String.Format or String.Concat instead of the concatenation operator?

  - by Kramii

  In C# it is possible to concatenate strings in several different ways: Using the concatenation operator: var newString = "The answer is '" + value + "'."; Using String.Format: var newString = String.Format("The answer is '{0}'.", value); Using String.Concat: var newString = String.Concat("The answer is '", value, "'."); What are the advantages / disadvantages of each of these methods? When should I prefer one over the others? The question arises because of a debate between developers. One never uses String.Format for concatenation - he argues that this is for formatting strings, not for concatenation, and that is is always unreadable because the items in the string are expressed in the wrong order. The other frequently uses String.Format for concatenation, because he thinks it makes the code easier to read, especially where there are several sets of quotes involved. Both these developers also use the concatenation operator and String.Builder, too.

• Programmatically clean Word generated HTML while preserving styles?

  - by GeReV

  In my current company, we have this decade old... let's call it a "Hello World" application. While wanting to create a newer version of it, we also want to preserve older entries. These older entries contain hideous Word generated HTML which was never filtered before. If and when we move to a newer system, I'd generally prefer to have that HTML cleaned and filtered in order to have the site comply with HTML standards as much as possible. However, just cleaning that code like Jeff Atwood described in his blog or in any other way I know of would also ruin the style and formatting. Now, that just might cause our users to revolt and then all hell will break loose... Not a very good idea. Question is -- can Word's HTML be cleaned while preserving basic formatting? (e.g: coloring, italicized, bold text and so on) Preferably using publicly available code or library, such as HTML Tidy, examples in C# would be much appreciated. Thanks!

• Best Fit Scheduling Algorithim

  - by Teegijee

  I'm writing a scheduling program with a difficult programming problem. There are several events, each with multiple meeting times. I need to find an arrangement of meeting times such that each schedule contains any given event exactly once, using one of each event's multiple meeting times. Obviously I could use brute force, but that's rarely the best solution. I'm guessing this is a relatively basic computer science problem, which I'll learn about once I am able to start taking computer science classes. In the meantime, I'd prefer any links where I could read up on this, or even just a name I could Google.

• Remove a keyboard shortcut binding in Visual Studio using Macros

  - by Pete

  Hi. I have a lot of custom keyboard shortcuts set up. To avoid having to set them up every time I install a new visual studio (happens quite a lot currectly, with VS2010 being in beta/RC) I have created a macro, that sets up all my custom commands, like this: DTE.Commands.Item("ReSharper.ReSharper_UnitTest_RunSolution").Bindings = "Global::Ctrl+T, Ctrl+A" My main problem is that Ctrl+T is set up to map to the transpose char command by default. So I want to remove that default value in my macro. I have tried the following two lines, but both throw an exception DTE.Commands.Item("Edit.CharTranspose").Bindings = "" DTE.Commands.Item("Edit.CharTranspose").Bindings = Nothing Although they kind of work, because they actually remove the binding ;) But I would prefer the solution that doesn't throw an exception. How is that done?

• How to generate all variations with repetitions of a string?

  - by Svenstaro

  I want to generate all variations with repetitions of a string in C++ and I'd highly prefer a non-recursive algorithm. I've come up with a recursive algorithm in the past but due to the complexity (r^n) I'd like to see an iterative approach. I'm quite surprised that I wasn't able to find a solution to this problem anywhere on the web or on StackOverflow. I've come up with a Python script that does what I want as well: import itertools variations = itertools.product('ab', repeat=4) for variations in variations: variation_string = "" for letter in variations: variation_string += letter print variation_string Output: aaaa aaab aaba aabb abaa abab abba abbb baaa baab baba babb bbaa bbab bbba bbbb Ideally I'd like a C++ program that can produce the exact output, taking the exact same parameters. This is for learning purposes, it isn't homework. I wish my homework was like that.

• I would like to build an app that alerts me when road traffic is high or low. Where can I get the r

  - by MedicineMan

  I'm sitting at work, waiting for traffic to die down. The thought occurred to me. I know when I want to go home, why don't I have an app that watches traffic for me? I also know that there are a lot of smart people on stackoverflow. Where can I get live traffic data for the san francisco bay area region? The data source should be timely, accurate, and as high resolution as possible. I would like to build an app on top of a service, rather than watch google maps or watch another website. I would prefer that I not have to scrape the data, but I have been know to do this in the past when no other option exists.

• RegEx - Indexed\Arrayed Named Capture groups?

  - by Josh

  I have a situation where something can appear in a format as follows: ---id-H-- Header: data Another Header: more data Message: sdasdasdasd Message: asdasdasdasd Message: asdasdasd There may be many messages, or just a couple. I'd prefer not having to step outside of RegEx, because I am using the RegEx to parse some header information above the messages and the messages along with the headers are part of the text I am parsing. The messages attached into the text might be many. I would also like to use named capture groups, so something like Message: (?<Message[index of match]>.+) Where it matches the match as many times as it can with the index filled in. Does anything like this exist in RegEx? (I will eventually be using this in Perl)

• Latex editor for windows that works with unicode

  - by Anna

  Hello, I need to write Hebrew text in Latex. I am currently working on Windows with TeXnicCenter. I was pretty happy with this tool, up until the time when I needed to write Hebrew text. My regular alt-shift just won't change the language (I even downloaded the last alpha version, which was supposed to solve the problem, but it didn't). So I'm looking for another latex editor for windows that will let me write Hebrew. Please advice. Note: I know that it is possible with Lyx, but I prefer a real Latex editor.

• How to set Height of items in XAML so they always occupy the same proportion of available space in p

  - by aoven

  I have an ItemsControl with the following ItemTemplate: <DataTemplate x:Key="myItemTemplate"> <TextBlock Height="???" Text="{Binding Path=Description}" /> </DataTemplate> My question is, how do I set the Height of the TextBlock in the template so that it automatically assumes ItemsControl.Height div ItemsCount amount of vertical space? When there's only one item, I'd like it to be the full height of container, when there're two, each should be half the size, and so on. If possible, I'd prefer to do this completely in XAML to keep my ViewModel clean of UI logic.

• Netbeans 6.8 groovy files in src/main/java

  - by Jeff Storey

  I have a new netbeans maven/groovy project, and I actually prefer to mix my java and groovy files in src/main/java and src/test/java (I find it easier to navigate this way and my pom reflects this configuration). However, when I have my project setup this way in Netbeans 6.8, it always shows the generated-sources folder in error. The stubs generated from groovy files in src/test/java can't be opened by netbeans and given an error that they can't be parsed. However, in windows explorer the files are in tact. Netbeans can run the project but it continues to prompt me that some files are in error (even though I know they're not). It's like netbeans isn't refreshing itself. Any thoughts on how to fix this? thanks, Jeff

• iPhone -- initialization partly by NSKeyedUnarchiver and partly by other means

  - by William Jockusch

  I have an object myObj, which is an instance of a class MyClass. Some of its instance variables always have their initial values passed in by the calling code. Other instance variables will be initialized in one of two ways. For an instanceArray of type NSMutableArray, the possibilities are either instanceArray = [[NSMutableArray alloc]init]; or instanceArray = [someKeyedUnarchiver decodeObjectForKey: kInstanceArrayKey]; The calling code should determine which of the above will be used. Any particular design pattern I should prefer?

• MLS Integration (RETSBond RI or?)

  - by prodigitalson

  I'm looking Specifically for some detailed information on RETSBond Integrator (RI) or something similar. Has anyone used it? Drawbacks? benefits? What I need is something that provides a PHP API out of the box or some kind of RPC exposure. This thing seems to provide an API for batching the MLS server and putting in my own DB which is acceptable although ideally I'd prefer something totally external. Do any MLS services provide that that you are aware of? I realize this is somewhat subjective but I'm looking for a starting point on different services/vendors to research.

• How to set up 3rd party developer portal

  - by Michael

  I am developing a web service and depend on 3rd party developers to write client applications for it. I need to set a developer portal, a web site where existing and potential developers would find documentation html pages doc files for download libraries downloads wiki forums support ticketing system. There should be a public part and a part protected by login. I want only logged in users to submit tickets, for example. I don't want to host it. I would prefer a generic design based on a sensible template, where I can add minimal customization, such as logo. I don't want to add code to get any of the above functionality. I will do all that if necessary, but I'd hope there would be an online service to do thing like that. What services would you guys recommend?
