  • Generic TryParse

    - by Piers Myers
    I am trying to create a generic extension that uses 'TryParse' to check if a string is a given type: public static bool Is<T>(this string input) { T notUsed; return T.TryParse(input, out notUsed); } this won't compile as it cannot resolve symbol 'TryParse' As I understand, 'TryParse' is not part of any interface. Is this possible to do at all?

  • Grails Domain.get() returns null for mongo's ObjectId

    - by Shashank Agrawal
    I'm using grails 2.3.5 with mongodb 3.0.1 and no hibernate installed. I've a domain class which uses mongo's ObjectId. import org.bson.types.ObjectId class Category { ObjectId id String name } And has a record in mongo database: { "_id": ObjectId("53f6c34c33a429240e2ab471"), "name": "art", "version": NumberLong("41") } When I do, Category.get(new ObjectId("53f6c34c33a429240e2ab471")) somewhere in grails app, it returns null but when I do Category.get("53f6c34c33a429240e2ab471") it then actually returns the result. Why, get() method does not process ObjectId type?

    - by Kaido
    I have built an application which uses user executable through WScript com object. Now the main program is located in C:\Program files\Myapp Curl executable is located in C:\Curl But it looks like my application is unable to execute curl if main application is in Program files. If i move it to another location it can execute curl nicely. Problem occurs only on Windows Xp on Vista and Win7 it works perfectly. Is there any special permissions i have to give to my app or what?

  • Get just the hour of day from DateTime using either 12 or 24 hour format as defined by the current c

    - by InvisibleBacon
    .Net has the built in ToShortDateString() function for DateTime that uses the CultureInfo.CurrentCulture.DateTimeFormat.ShortTimePattern format. It returns something like this for en-US: "5:00 pm". For a 24 hour culture such as de-DE it would return "17:00". What I want is a way to just return just the hour (So "5 pm" and "17" in the cases above) that works with every culture. What's the best/cleanest way to do this? Thanks!

  • How can I get started with PHPUnit, where my class construct requires a preconfigured db connection?

    - by Ben Dauphinee
    I have a class that uses a lot of database internally, so I built the constructor with a $db handle that I am supposed to pass to it. I am just getting started with PHPUnit, and I am not sure how I should go ahead and pass the database handle through setup. public function setUp(/*do I pass a database handle through here, using a reference? aka &$db*/){ $this->_acl = new acl; } public function __construct(Zend_Db_Adapter_Abstract $db, $config = array()){

    Hi everyone, Please suggest me a C# cross-platform solution to copy a File with progress. The method should be able to copy the file on Mono as well on .NET. P.S. Most of the solutions here refers to CopyFileEx (which uses PInvoked and I am not sure if this will works on a Mono) P.S.S. Many thanks in advance! -- Murat

  • Apache as Reverse Proxy for CouchDB

    - by Overflown
    I'm thinking of a web app that uses CouchDB extensively, to the point where there would be great gains from serving with the native erlang HTTP API as much as possible. Can you configure Apache as a reverse proxy to allow outside GETs to be proxied directly to CouchDB, whereas PUT/POST are sent to the application internal logic (for sanitation, authentication...)? Or is this unwise -- the CouchDB built-in authentication options just seem a little weak for a Web App. Thanks

  • Python: Pass parameter one time, but use more times

    - by Gabriel L. Oliveira
    I'm trying to do this: commands = { 'py': 'python %s', 'md': 'markdown "%s" "%s.html"; gnome-open "%s.html"', } commands['md'] % 'file.md' But like you see, the commmands['md'] uses the parameter 3 times, but the commands['py'] just use once. How can I repeat the parameter without changing the last line (so, just passing the parameter one time?)

    I created a text editor in C# and I use a special file extension for the XML file that my program uses. When I use "Open With..." from the Windows context menu, my program doesn't read the file and I get an error. How do I fix this?

  • What is the most useful programming language that no one is using?

    - by dbyrne
    What language do you find incredibly useful that no one else seems to care about? I am not looking for the language with the coolest features, but the language that makes you the most productive. I realize that a productive language that no one uses is a bit of an oxymoron. My personal choice would probably be ruby without rails, but I am sure others can come up with some better answers.

  • Use Apache authentication in Django without popup

    - by chernevik
    I am using Apache to authenticate users for Django, but I would like to do so without the popup form that Apache uses in its basic configuration. How do I embed the login form within a page while still using Apache for authentication? That is, I'd like a page that says "Please login" and provides a form asking for username and password, and passes this information on to Apache for authentication. (I'd do this over an SSL connection, of course.)

  • Email SMTP validator

    - by Hrvoje
    I need to send hundreds of newsletters, but would like to check first if email exists on server. It's called smtp validation, at least i think so, based on my research on net. There's several libraries that can do that, and also a page with open-source code in asp (http://www.coveryourasp.com/ValidateEmail.asp#Result3), but I have hard time reading classic asp, and it seams that it uses some third-party library... Does someone have code for smtp validation in c#, and/or general explanation of how it works?

  • jQuery attribute auto added to elements

    - by macca1
    After using the IE8 built in Developers Tools for the first time, I noticed jQuery is attaching an attribute to some of my elements: I've never noticed this before. In fact, this doesn't show up in Firebug... I'm only seeing it for the first time now in IE8 Developer Tools. Does anyone know what jQuery uses this for, and why it's hidden in firebug?

  • JavaScript Music Player with progress bar?

    - by pfunc
    I am creating a little JavaScript music player that sits on the btottom of the page, a lot like streampad. But streampad uses a flash progress bar for the song and JavaScript for everything else and I am having a hard time finding anyone who does this with JavaScript alone. Can anyone point me in the right direction on how this can be done (preferably without using HTML5)?

  • Resizing an iframe based on content

    - by larssg
    I am working on an iGoogle-like application. Content from other applications (on other domains) is shown using iframes. How do I resize the iframes to fit the height of the iframes' content? I've tried to decipher the javascript Google uses but it's obfuscated, and searching the web has been fruitless so far. Update: Please note that content is loaded from other domains, so the same-origin policy applies.

  • spring security filter-chain regex pattern

    - by lewap
    In my application which uses spring security I want to define two different areas both using their own spring security filter-chain. My question is: is it possible to define two regex expressions as follows: every path starting with /foobar/* every other path not starting with /foobar The important part here is that the second path should also match if somewhere within it, but not in the beginning, it cotains the /foobar/ string. Thanks
