  • method to find my UDP socket's "real" port?

    - by yairchu
    Is there any free service to which I could send a UDP packet and it would respond telling me what is my "real" UDP port? (my application is behind a NAT) This kind of service could allow me to make a p2p coordination server with normal php hosting. The p2p clients would know their UDP ports from this service They will then contact my server over HTTP (which is what regular web hosting allows) and tell it their port (and ip, which is normally supplied to cgi scripts) My server will give the clients the IP addresses and ports of the other clients.

  • How to inherit from a library in a MVC.NET view

    - by Dofs
    I am trying to implement CKFinder in my MVC.Net website, but the default setup only works for regular asp.net websites, so I am trying to alter it to work. One page inherits from a library CKFinder.Connector.Connector. In the old days my aspx would just inherit="CKFinder.Connector.Connector", but how is this done in MVC.NET? Is Inherits="System.Web.Mvc.ViewPage<CKFinder.Connector.Connector>" the same?

  • Automatically copy files without overwriting, but creating numbered ones instead

    - by user1688322
    I need to copy files at a regular interval, eg once an hour so I tried setting up an xcopy batch saying it should copy the files it needs to copy to another folder. Now when it copies, it overwrites the files which is not what it is supposed to do. When a file is copied, it should create a new file instead, named something like File.txt, File-COPY1.txt, File-COPY2.txt or something like that. Any way to do that? Thanks in advance.

  • Pin fogbugz tab in visual studio

    - by boris callens
    The fogbugz plugin for visual studio opens up a tab right next to your regular code tabs with in it the fogbugz window. Tiny bit lame if you ask me, but I can accept that. Is there a way however to make that tab pinned? So I cannot accidently close it and it will stay the first tab at all times?

  • How to validate hostname in perl?

    - by embedded
    Hi, I need to come up with a regular expression to validate hostname against RFC-1123 and RFC-952. Right now I'm using this: ^(?=.{1,255}$)[0-9A-Za-z](?:(?:[0-9A-Za-z]|\b-){0,61}[0-9A-Za-z])?(?:\.[0-9A-Za-z](?:(?:[0-9A-Za-z]|\b-){0,61}[0-9A-Za-z])?)*\.?$/ but this does not do the trick since it does not catch a. as invalid hostname. How do I enhance the reg expression to comply with those RFCs? Thanks

  • Can't sign into linkedin when using a QT4 (WebKit-based) browser?

    - by Inshim
    I started using the lightweight QT4 browser for some of the time on my Mac. Most simple websites, and even quite a few AJAX-heavy web apps, work for me flawlessly, including gmail (!) However, with LinkedIn, I can't even manage to sign in. Even when I change the useragent to one of a regular browser, it keeps kicking me out. Any ideas what could be wrong and for some workaround? Thanks!

  • Alternative to Windows Azure tables out of the cloud

    - by John Grey
    Hi :) I'm developing a .NET app, which needs to run both on Azure and on regular Windows Servers(2003). It needs to store a few GB of data and SQL Azure is too expensive for me, so I'll use Azure tables in the cloud version. Can you recommend a storage solution, which will run on standalone servers and have an API and behavior similar to Azure tables? From what I've seen Server AppFabric does not include Tables. TIA

  • Foreign key pointing to different tables

    - by Álvaro G. Vicario
    I'm implementing a table per subclass design I discussed in a previous question. It's a product database where products can have very different attributes depending on their type, but attributes are fixed for each type and types are not manageable at all. I have a master table that holds common attributes: product_type ============ product_type_id INT product_type_name VARCHAR E.g.: 1 'Magazine' 2 'Web site' product ======= product_id INT product_name VARCHAR product_type_id INT -> Foreign key to product_type.product_type_id valid_since DATETIME valid_to DATETIME E.g. 1 'Foo Magazine' 1 '1998-12-01' NULL 2 'Bar Weekly Review' 1 '2005-01-01' NULL 3 'E-commerce App' 2 '2009-10-15' NULL 4 'CMS' 2 '2010-02-01' NULL ... and one subtable for each product type: item_magazine ============= item_magazine_id INT title VARCHAR product_id INT -> Foreign key to product.product_id issue_number INT pages INT copies INT close_date DATETIME release_date DATETIME E.g. 1 'Foo Magazine Regular Issue' 1 89 52 150000 '2010-06-25' '2010-06-31' 2 'Foo Magazine Summer Special' 1 90 60 175000 '2010-07-25' '2010-07-31' 3 'Bar Weekly Review Regular Issue' 2 12 16 20000 '2010-06-01' '2010-06-02' item_web_site ============= item_web_site_id INT name VARCHAR product_id INT -> Foreign key to product.product_id bandwidth INT hits INT date_from DATETIME date_to DATETIME E.g. 1 'The Carpet Store' 3 10 90000 '2010-06-01' NULL 2 'Penauts R Us' 3 20 180000 '2010-08-01' NULL 3 'Springfield Cattle Fair' 4 15 150000 '2010-05-01' '2010-10-31' Now I want to add some fees that relate to one specific item. Since there are very little subtypes, it's feasible to do this: fee === fee_id INT fee_description VARCHAR item_magazine_id INT -> Foreign key to item_magazine.item_magazine_id item_web_site_id INT -> Foreign key to item_web_site.item_web_site_id net_price DECIMAL E.g.: 1 'Front cover' 2 NULL 1999.99 2 'Half page' 2 NULL 500.00 3 'Square banner' NULL 3 790.50 4 'Animation' NULL 3 2000.00 I have tight foreign keys to handle cascaded editions and I presume I can add a constraint so only one of the IDs is NOT NULL. However, my intuition suggests that it would be cleaner to get rid of the item_WHATEVER_id columns and keep a separate table: fee_to_item =========== fee_id INT -> Foreign key to fee.fee_id product_id INT -> Foreign key to product.product_id item_id INT -> ??? But I can't figure out how to create foreign keys on item_id since the source table varies depending on product_id. Should I stick to my original idea?

  • Rewrite URL, regex help...

    - by Tony
    Hello, I am using the following Rewrite URL: RewriteRule /([^/?.]+) /somedir/somefile.aspx\?Name=$1 [NC,L] which works great for my use, but I need to restrict it to only act on text that does not contain a filename... for example, if I use the url www.somedomain.com/SomeName it works fine, but it also fires if I use www.somedomain.com/TestPage.aspx So I am not sure if I need an additional Rewtire rule, or if the current one can be modified to disallow any text with an extension, for example. Any help with this regular expression would be greatly appreciated.

  • htaccess blog feed redirect

    - by kb
    hi helpful people, i'm trying to get my old blogger blog feed URL (/blog/atom.xml) to redirect to my new blog feed URL (/blog/feed). A regular 301 redirect didn't work, and the advice given on the wordpress site, which is: RewriteRule ^oldfeed.php(.*)? /wordpress/?feed=newfeed [QSA] isn't quite cutting it either - probably because i'm not sure how to adjust the code for oldfeed to accomodate a directory. or for some other reason entirely! Can anyone help me with this? Thanks very much, kb

Am I missing something here maybe? Kind regards, Mark

  • Checking if app can run without admin rights?

    - by overtherainbow
    Hello To get Windows users to log on as regular users instead of admin, I need to check that all their applications run OK with limited rights. Is there an application specifically aimed at checking that an application can run with limited rights, or is SysInternals' Process Monitor what everyone uses for this purpose? Thank you.
