  • ASP.NET MVC & ADO.NET Entity Framework clientside validation

    - by JK
    Using aspnet mvc2 with the model auto-generated by entity framework: Is it possible to tell entity framework to auto-annotate all fields? eg: If database field says not null then add [Required] If DB field is a nvarchar(x) then add [StringLength(x)] And so on? What if the field name contains the string "email" eg CustomerEmail - can I get EF to auto-annotate that with an appropriate annotation ([Regex()] maybe) As I understand it, if the model fields are annotated, and I use both Html.ValidationMessageFor() and use if (ModelState.IsValid) in my controller, then that is all I need to do to have basic clientside input validation working? Thanks

  • ASP.NET connection pool question

    - by James Evans
    Does the same connection string used on two different physical servers hosting different web applications that talk to the same database draw connections from the same connection pool? Or are pooled connections confined to at the application level? I ask because I inherited a 7 year old .NET 1.1 web application which is riddled with in-line SQL, unclosed and undisposed sql connection and datareader objects. Recently, I was tasked to write a small web app that is hosted on another server and talks to the same database and therefore used the same database connection string. I created a LINQ object to read and write the one table required by the app. Now the original .NET 1.1 app is throwing exceptions like "Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached." Maybe these are unreleated, but wanted to get your opinions to make sure I cover all my bases. Thanks!

  • Refresh backend in GWT development

    - by T.K.
    I am developing a GWT application that uses EJB and other Java EE 6 technology as the backend. I am currently using the GWT 2.0 plugin for Safari. When I change my GWT client side code and save in my IDE (NetBeans), all that's required is a simple reload in the browser for the changes to become active. That works great! However, often I work on the server-side (the EJBs, GWT server code, etc) and then something in on the GWT client side. Any changes done to the server-side do not appear to incrementally deploy to the Glassfish V3 server. Currently I close the GWT Development Mode application, and then recompile the EJBs, and then go back into GWT Development mode. That is tedious. Any better way of doing this? I tried the "deploy on save" option in NetBeans but it does not seem to do the trick.

  • Does Ivy's url resolver support transitive retrieval?

    - by Sean
    For some reason I can't seem to resolve the dependencies of my dependencies when using a url resolver to specify a repository's location. However, when using the ibiblio resolver, I am able to retrieve them. For example: <!-- Ivy File --> <ivy-module version="1.0"> <info organisation="org.apache" module="chained-resolvers"/> <dependencies> <dependency org="commons-lang" name="commons-lang" rev="2.0" conf="default"/> <dependency org="checkstyle" name="checkstyle" rev="5.0"/> </dependencies> </ivy-module> <!-- ivysettings file --> <ivysettings> <settings defaultResolver="chained"/> <resolvers> <chain name="chained"> <url name="custom-repo"> <ivy pattern="http://my.internal.domain.name/ivy/[organisation]/[module]/[revision]/ivy-[revision].xml"/> <artifact pattern="http://my.internal.domain.name/ivy/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]"/> </url> <url name="ibiblio-mirror" m2compatible="true"> <artifact pattern="http://mirrors.ibiblio.org/pub/mirrors/maven2/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" /> </url> <ibiblio name="ibiblio" m2compatible="true"/> </chain> </resolvers> </ivysettings> <!-- checkstyle ivy.xml file generated from pom via ivy:install task --> <?xml version="1.0" encoding="UTF-8"?> <ivy-module version="1.0" xmlns:m="http://ant.apache.org/ivy/maven"> <info organisation="checkstyle" module="checkstyle" revision="5.0" status="release" publication="20090509202448" namespace="maven2" > <license name="GNU Lesser General Public License" url="http://www.gnu.org/licenses/lgpl.txt" /> <description homepage="http://checkstyle.sourceforge.net/"> Checkstyle is a development tool to help programmers write Java code that adheres to a coding standard </description> </info> <configurations> <conf name="default" visibility="public" description="runtime dependencies and master artifact can be used with this conf" extends="runtime,master"/> <conf name="master" visibility="public" description="contains only the artifact published by this module itself, with no transitive dependencies"/> <conf name="compile" visibility="public" description="this is the default scope, used if none is specified.

Is this possible? Any help would be greatly appreciated.

  • Dynamically loading CSS and JavaScript using Prototype

    - by Salman A
    I have a classic ASP application that I've been constantly trying to modularize. Currently, almost all pages are divided in to two pages: an outer page that contains the layout, header, sidebar, footer an inner page that contains ASP code The outer pages use dreamweaver templates so updating layout and replicating changes is easy. The inner pages are managed by me. Now here is the problem: I had to add a lightbox to one page, I chose Lightbox 2 which requires Prototype. I ended up adding Prototype on every page, assuming that sooner or later I'll upgrade all pages, forms, ajax requests and other javascript to use Prototype. I've now added two other plugins -- Modalbox and Protofade; each with a pair of .JS and .CSS files. Since I'll be using these three plugins on specific set of pages I am wondering if I can load the required CSS and JS files dynamically. I do not want to access the document head and add include files there, I'll have to do this from inside a DIV where all ASP code is supposed to go.

  • What is an SSH key?

    - by acidzombie24
    I signed up for github and notice the ssh key option which looked interesting. I originally expected something like an ssl key (name, co name, etc). After going through it i notice i only put a password and it is always myuser@comp-name (this is windows). Why? I thought it was a user/pass id and i can create separate keys for separate purpose for privacy reasons. Now i see i am required to use one to create a repository. Also i see something about a 'private key file' when looking at options. What exactly is an SSH Key and how can i create a separate user without creating a separate login in windows.

  • Setting amount of time to pass when sending emails in a loop

    - by Obay
    Forgive me for this noob question, but is there such a setting that sets a certain amount of time (e.g. milli/seconds) that has to pass in between sending emails through a script? How is that setting called and where do I change that setting? I'll give an example: I used to have a PHP script that sends emails like so: for ($i=0; $i<count($emails); $i++) { mail($email[$i],'test','test'); } It turned out that not all emails were sent successfully because the script ran so fast that there was not enough time in between sending emails that was required by the server. Did I make sense?

  • Modify Emdeded String in C# compiled exe

    - by nitefrog
    I have an issue where I need to be able to have a compiled exe ( .net 3.5 c# ) that I will make copies of to distribute that will need to change a key for example before the exe is sent out. I cannot compile each time a new exe is needed. This is a thin client that will be used as part of a registration process. Is it possible to add a entry to a resource file with a blank value then when a request comes in have another application grab the blank default thin client, copy it, populate the blank value with the data needed. If yes how? If no do you have any ideas? I have been scratching my head for a few days now and the limitation as due to the boundaries I am required to work in. The other idea I has was to inject the value into a method, which I have no idea how I would even attempt that. Thanks.

  • Capturing USB Plug/Unplug events in Firemonkey

    - by radsdau
    [RAD Studio XE3 / C++] I have a FMX project running in Windows only at this stage, but I need to detect events when USB devices are connected and disconnected. I have a similar VCL app that can do this fine, but the Application-HookMainWindow is not exposed in FMX (only VCL). Is there an elegant way to handle this? Or do I have to hack some VCL stuff into my FMX app to make that work? I'd imagine I have to abstract it so I can support other platforms down the track. For the meantime though I need to get the Windows solution working. If the 'VCL hack' thing is required, how would I reference the vcl::Forms::Application from within my Fmx app? Cheers.

  • Random access gzip stream

    - by jkff
    I'd like to be able to do random access into a gzipped file. I can afford to do some preprocessing on it (say, build some kind of index), provided that the result of the preprocessing is much smaller than the file itself. Any advice? My thoughts were: Hack on an existing gzip implementation and serialize its decompressor state every, say, 1 megabyte of compressed data. Then to do random access, deserialize the decompressor state and read from the megabyte boundary. This seems hard, especially since I'm working with Java and I couldn't find a pure-java gzip implementation :( Re-compress the file in chunks of 1Mb and do same as above. This has the disadvantage of doubling the required disk space. Write a simple parser of the gzip format that doesn't do any decompressing and only detects and indexes block boundaries (if there even are any blocks: I haven't yet read the gzip format description)

  • Why is the base() constructor not necessary?

    - by Earlz
    Hello, I have a class structure like abstract class Animal { public Animal(){ //init stuff.. } } class Cat : Animal { public Cat(bool is_keyboard) : base() //NOTE here { //other init stuff } } Now then, look at the noted line. If you remove : base() then it will compile without an error. Why is this? Is there a way to disable this behavior? I have had multiple bugs now from forgetting the base() which I would have thought to be required on such a special thing as a constructor.

  • Subversion terminology. Difference between projects, modules and root directories

    - by aioobe
    I'm setting up a repository for me and some colleagues. I have a subversion repository at hand, and all required rights. The usual directory-skeleton has been set up for me (branches, tags and trunk). Now I'm about to create a directory for me and my colleagues to put our files in. I'm quite sure the right place to put it is in trunk. Now here and there in tutorials, I see terms like "modules" and "projects" such as in Checking Out a Project - svn checkout svn checkout http://host_name/svn_dir/repository_name/project/trunk proj Is proj in the above line some glorified directory in trunk? Should I do something else than a checkout on trunk, mkdir and then commit when creating a directory for me and my colleagues? Whats the difference between a project, a directory in trunk and a module?

  • PHP: Replace umlauts with closest 7-bit ASCII equivalent in an UTF-8 string

    - by BlaM
    What I want to do is to remove all accents and umlauts from a string, turning "lärm" into "larm" or "andré" into "andre". What I tried to do was to utf8_decode the string and then use strtr on it, but since my source file is saved as UTF-8 file, I can't enter the ISO-8859-15 characters for all umlauts - the editor inserts the UTF-8 characters. Obviously a solution for this would be to have an include that's an ISO-8859-15 file, but there must be a better way than to have another required include? echo strtr(utf8_decode($input), 'ŠŒŽšœžŸ¥µÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝßàáâãäåæçèéêëìíîïðñòóôõöøùúûüýÿ', 'SOZsozYYuAAAAAAACEEEEIIIIDNOOOOOOUUUUYsaaaaaaaceeeeiiiionoooooouuuuyy'); UPDATE: Maybe I was a bit inaccurate with what I try to do: I do not actually want to remove the umlauts, but to replace them with their closest "one character ASCII" aequivalent.

  • On Edit Grid view Multiple row edit validation

    - by franics
    I am using a telerik radgrid so there are around 5 columns each column edittemplate contains a control along with a required field validator and also a property called AllowMultiRowEdit is set to true so i am able to multiple rows in edit mode. If any of the values are cleared the for multiple rows I want only those to be validated on update of that particular row. So i implemented the Grids item data bound event find each and every validator along with the update button and set a unique validation group. The above implementation most times but fails at some time. Is there any other way of going about this ?

  • Switch between views in Android

    - by ZelluX
    Hi, all I'm writing an Android application with multiple Tabs. The content of each tabs is determined by XMLs on the Internet, and it could be WebView for HTML rendering, GridView for photo displaying, etc. I'm going to delay downloading of those XML until the tab is clicked. Upon clicking the application will download corresponding XML from the Internet, and then choose suitable View for it. Currently I have written a MyViewDelegate and use TabSpec.setContent() to set the spec pointing to MyViewDelegate: spec = tabHost.newTabSpec(tabName[i]); intent = new Intent().setClass(this, HomeActivity.class); spec.setIndicator(title[i]); spec.setContent(new MyViewDelegate(this, tabName[i])); tabHost.addTab(spec); My problem is, after MyViewDelegate is required to draw, how can I switch to WebView/GridView and initialize it? Many thanks.

  • Any experience on Sitecore CMS using Windows Sharepoint Services?

    - by Marcin B
    Hi guys, I plan to develop a solution based on Sitecore CMS which would allow the client company to manage their documents in a Sharepoint-fashion (versioning, diffs??). Of course, we're after limiting the number of licences required for the project, and the client doesn't yet have licences for MOSS, so we couldn't simply use the Sitecore Sharepoint Connector which from everything I read requires the MOSS installation, and won't work with bare WSS. From what I know Sitecore CMS doesn't version documents as such, but is there a possibility for a workaround? Ideally we'd work with Documents and Files in the same fashion as with normal pages, which enables DIFFs and stuff. Any ideas? Thanks, Marcin B

  • Block All Keyboard Input in a Linux Application (Using Qt or Mono)

    Hi, I'm working on a online quiz client where we use a dedicated custom-made linux distro which contains only the quiz client software along with text editors and other utility software. When the user has started the quiz, I want to prevent him/her from minimizing the window/closing it/switching to the desktop or other windows. The quizzes can be attempted using only the mouse, so I need the keyboard to be completed disabled for the period of the quiz. How could I do this, using Qt or Mono? I'm ready to use any low-level libraries/drivers, if required. Thanks Evans

  • Maven test failure xml FileNotFoundException

    - by James
    My Maven build is failing on Hudson with a FileNotFoundException, I do not get the same failure through NetBeans. The FileNotFoundException is for some xml files in the same packages as my test classes themselves. It would appear these are not getting copied as part of the build in the same way the class files are. Do I have to add something to my POM for the xml files to be copied? If any more information is required please let me know, I wanted to keep the question short incase it was something simple.

  • IoC from start to finish

    - by Dave
    I'm quite sure that IoC is the way to go for my application. There are a ton of articles and even questions here on SO that discuss the different containers. I've read several blogs today with partial examples. I am personally leaning towards starting with the CommonServiceLocator and Unity as two way to solve the same problem -- I just need a bunch of assemblies to get data from a database, which I assume is what needs to be injected everywhere. I've yet to find any sites that really take a problem from beginning to end, with concrete code examples. For example, I've yet to find one that discusses an IServiceLocator and how to actually register it (or do whatever is required to make it known). What are your favorite posts / articles / SO questions that can take a noob from start to finish with the implementation?

  • sync framework server to server synchronization

    I have kind of a such scenario: Here i need to synchronize local server database with main DB server(example: computers in office are connected to office server and they use it like a local server, so that no sync is required.BUT computers in other office work with their local server too and we need synchronization between the offices though the main DB server.). As i see i cant use SQLCompact here. Is there a provider to do the server-to-server synchronization right from the client? If no can someone provide a sample of solution of how to manage such situation?

  • Efficient mass string search problem.

    - by Monomer
    The Problem: A large static list of strings is provided. A pattern string comprised of data and wildcard elements (* and ?). The idea is to return all the strings that match the pattern - simple enough. Current Solution: I'm currently using a linear approach of scanning the large list and globbing each entry against the pattern. My Question: Are there any suitable data structures that I can store the large list into such that the search's complexity is less than O(n)? Perhaps something akin to a suffix-trie? I've also considered using bi- and tri-grams in a hashtable, but the logic required in evaluating a match based on a merge of the list of words returned and the pattern is a nightmare, and I'm not convinced its the correct approach.
