  • Computed column should result to string

    - by strakastroukas
    Here is a snap of my database. Both col1 and col2 are declared as int. My ComputedColumn currently adds the Columns 1 and 2, as follows... col1 col2 ComputedColumn 1 2 3 4 1 5 Instead of this, my ComputedColumn should join the columns 1 and 2 (includimg the '-' character in the middle) as follows... col1 col2 ComputedColumn 1 2 1-2 4 1 4-1 So, what is the correct syntax?

  • Pylons error handling

    - by TJ Huffington
    Hello, I am just getting started with Pylons and am confused as to how to account for exceptions. What is the proper way to error check user input (ensure a correct email address, check that it doesn't yet exist in the database, etc ...)? Should these checks go inside the model classes or somewhere else? Sample code would be great.

  • Crystal Reports from Access DB in FrontPage (plus RealPlayer integration)

    - by Jason
    Hey guys, My boss has some interesting requirements for his next project and insists that we try to implement some Crystal Reports on our Access database (on his computer) into a FrontPage document (for ease of maintenance). After that, he wants an MP3 to be embedded using a RealPlayer widget because that's the only one that he likes. I'm not really sure how to do any of this. What's the best way to go about this? Any help would be greatly appreciated.

  • Why does Module::Build's testcover gives me "use of uninitialized value" warnings?

    - by Kurt W. Leucht
    I'm kinda new to Module::Build, so maybe I did something wrong. Am I the only one who gets warnings when I change my dispatch from "test" to "testcover"? Is there a bug in Devel::Cover? Is there a bug in Module::Build? I probably just did something wrong. I'm using ActiveState Perl v5.10.0 with Module::Build version 0.31012 and Devel::Cover 0.64 and Eclipse 3.4.1 with EPIC 0.6.34 for my IDE. UPDATE: I upgraded to Module::Build 0.34 and the warnings are still output. *UPDATE: Looks like a bug in B::Deparse. Hope it gets fixed someday.* Here's my unit test build file: use strict; use warnings; use Module::Build; my $build = Module::Build->resume ( properties => { config_dir => '_build', }, ); $build->dispatch('test'); When I run this unit test build file, I get the following output: t\MyLib1.......ok t\MyLib2.......ok t\MyLib3.......ok All tests successful. Files=3, Tests=24, 0 wallclock secs ( 0.00 cusr + 0.00 csys = 0.00 CPU) But when I change the dispatch line to 'testcover' I get the following output which always includes a bunch of "use of uninitialized value in bitwise and" warning messages: Deleting database D:/Documents and Settings/<username>/My Documents/<SNIP>/cover_db t\MyLib1.......ok Use of uninitialized value in bitwise and (&) at D:/Perl/lib/B/Deparse.pm line 4252.

  • sha1(password) encryption

    - by Jason
    Alright, so I tried to make my users info super secure by adding '" . sha1($_POST['password']) . "' when inserting their password when they register. THAT WORKS great, looking at the database, I have no clue what their password is. Now the problem is logging in. I'm running some tests and when I try to log in, the password 12345 doesn't match the encrypted password using "$password=sha1($_POST['mypassword']);" Any idea's why?

  • NHibernate second-level cache with external updates.

    - by SztupY
    I've got a web application that is 99% read-only, with a separate service that updates the database at specific intervals (like every 10 minutes). How can this service tell the application to invalidate it's second-level cache? Is it actually important? (I don't actually care if I have too much stale data) If I don't invalidate the cache how much time is needed to the records to get updated (if using SysCache)

  • How do I check SQLite3 syntax?

    - by Benjamin Oakes
    Is there a way to check the syntax of a SQLite3 script without running it? Basically, I'm looking for the SQLite3 equivalent of ruby -c script.rb, perl -c script.pl, php --syntax-check script.php, etc. I've thought of using explain, but most of the scripts I'd like to check are kept around for reference purposes (and don't necessarily have an associated database). Using explain would also make it hard to use with something like Syntastic. (That is, I'm only wanting to check syntax, not semantics.)

  • What is a dictionary attack?

    - by Chris
    When we say dictionary attack, we don't really mean a real dictionary, do we? My guess is we mean a hacker's dictionary i.e. rainbow tables, right? My point is we're not talking about someone keying different passwords into the login box, we're talking about someone who has full access to your database (which has hashed passwords, not plain passwords) and this person is reversing the hashes, right?

  • Best forum solution for symfony

    - by Zoja
    I'm looking for a good solution to integrate a forum in a symfony application. Something like phpBB. I've seen the plugins to integrate just the user of phpBB with symfony but that's not enough, and mapping database tables is a lame aprouch. So if anybody knows a good working component of a forum that would go well with a symfony app then I would really apreciate it :) Thanks !

  • NHibernate - auto generate timestamp on create and update ?

    - by driis
    I am trying to map an entity in NHibernate, that should have an Updated column. This should be the DateTime when the entity was last written to the database (either created or updated). I'd like NHibernate to control the update of the column, so I don't need to remember to set a property to the current time before updating. Is there a built-in feature in NHibernate, that can handle this for me ?
