• NHibernate will insert but not update after move to host with shared server running mysql.

  - by Andy LifeBrixx

  Hi, I have a site running MVC and Nhibernate (not fluent) using standard session per request in an http module, runs fine locally (also with mysql) but after a move to a hosting provider no update statements are being issued. I can insert but not update, no exceptions are raised, I have the 'show_sql' option switched on which locally shows the update statements being issued but on the server no update statements are logged. I don't think NHProf is an option for me as I can only run asp.net apps on my shared server, are there any other methods of diagnosing NH issues like this ? Anyone had a similar issue ? Cheers, A

• Scope of Constants in Ruby Modules

  - by user204078

  I'm having a little problem with constant scope in mixin modules. Let's say I have something like this module Auth USER_KEY = "user" unless defined? USER_KEY def authorize user_id = session[USER_KEY] def end The USER_KEY constant should default to "user" unless it's already defined. Now I might mix this into a couple of places, but in one of those places the USER_KEY needs to be different, so we might have something like this class ApplicationController < ActionController::Base USER_KEY = "my_user" include Auth def test_auth authorize end end I would expect that USER_KEY would be "my_user" when used in authorize, since it's already defined, but it's still "user", taken from the modules definition of USER_KEY. Anyone have any idea how to get authorize to use the classes version of USER_KEY?

• Help constructing query - Compare columns and replace numbers

  - by Tommy

  I have a feeling that this query is pretty easy to construct, I just can't figure it out. I want to replace all numbers in table X column C, with numbers in table Z column A, where numbers from table X column C matches numbers in table Z column B. I hope that makes sense. Perhaps a little background information will make it clearer. I've converted from one CMS to another, and the module I used to convert mapped the ids to the new database. Table X column A is the new id's. Table X column B is the old id's. Table Z is the table for an image gallery that I migrated, and column C contains the id's of the images owners. Can anyone crack this nut?

• What are the possible tags of "global" tag in Magento "config.xml" file?

  - by Knowledge Craving

  Can someone professional experienced Magento developer tell me how to accomplish the following in Magento? I want to know what are the possible tags that can fit in the "global" tag of the "config.xml" page of every module's etc folder? I have tried searching for this answer at many places in Internet but in vain. Please provide the full details along with it, because I want at least the users accessing this website find it useful enough, instead of scratching their heads. I really want a detailed explanation, because every newbie like me gets totally confused at this point. From what I know till now, is that in this page, you can set routers, rewrites, cron jobs, admin html, front-end html and many more. But without any strong concepts. So please I want that strong fundamental concept with a detailed explanation about it.

• How do I link to another action in Magento whilst passing a parameter to the controller?

  - by desbest

  I need to pass a parameter, because I would like to redirect back to the module and query string of the current page. So I can get from showdown/index?id=35 --click--- showdown/vote?id=1 showdown/vote?id=1 --redirect-- showdown/index?id=35 The vote action is not seen. (The redirect method doesn't work as it takes the index.php url only and no actions, and I cannot find a helper in Magento for creating hyperlinks.) Does Magneto have a link helper for this? Example of stuff I want: <a href="<?php echo Mage::Helper->Link->($url, $array); ?> then $array or whatever variables gets sent to the controller.

• Can JavaScript be overused?

  - by ledhed2222

  Hello stackoverflow, I'm a "long time reader first time poster", glad to start participating in this forum. My experience is with Java, Python, and several audio programming languages; I'm quite new to the big bad web technologies: HTML/CSS/JavaScript. I'm making two personal sites right now and am wondering if I'm relying on JavaScript too much. I'm making a site where all pages have a bit of markup in common--stuff like the nav bar and some sliced background images--so I thought I'd make a pageInit() function to insert the majority of the HTML for me. This way if I make a change later, I just change the script rather than all the pages. I figure if users are paranoid enough to have JavaScript turned off, I'll give them an alert or something. Is this bad practice? Can JavaScript be overused? Thanks in advance.

• Will Haskell be a good choice for my task?

  - by Narzanka

  I'm starting a new project and don't know which language to use. My 'must have' requirements are: Be able to run on Windows/LinuxMacOs natively (native executable) - user should be able to just run the exe (when on Windows for example) and see the results. No runtimes/interpreters (no jvm, clr, etc) - one file download should be enough to run the application. Full unicode support. Be able to manipulate OS threads (create them, run multiple tasks in parallel on multi-core CPUs, etc). Be reasonably fast (Python level performance and better). To have some kind of standard library that does low-level, mundane tasks. Not very niche and have some community behind it to be able to ask questions. My 'nice to have' requirements are: Language should be functional It should have good string manipulation capabilities (not necessarily regex) Not extremely hard to learn I'm thinking about Haskell now but keeping in mind OCaml as well. Please advice if my choice is correct.

• Why do C# and Java require everything to be in a class?

  - by Javier Badia

  It seemed like this question should have been asked before, but searching found nothing. I've always wondered what's the point of making us put every bit of code inside a class or interface. I seem to remember that there were some advantages to requiring a main() function like C, but nothing for classes. Languages like Python are, in a way, even more object oriented than Java since they don't have primitives, but you can put code wherever you want. Is this some sort of "misinterpretation" of OOP? After all, you can write procedural code like you would in C and put it inside a class, but it won't be object oriented.

• Grouping and retrieving most recent entry in a table for each group

  - by Lisa

  First off, please bear with me if I don't state the SQL question correctly. I have a table that has multiple columns of data. The selection criteria for my table groups based on column 1(order #). There could be multiple items on each order, but the item #'s are not grouped together. Example: Order Customer Order Date Order Time Item Quantity 123456 45 01/02/2010 08:00 140 4 123456 45 01/02/2010 08:30 270 29 123456 45 03/03/2010 09:00 140 6 123456 45 04/02/2010 09:30 140 10 123456 45 04/02/2010 10:00 270 35 What I need is a result like: Order Customer Order Date Order Time Item Quantity 123456 45 04/02/2010 09:30 140 10 123456 45 04/02/2010 10:00 270 35 This result shows that after all the changes the final order includes 10 of Item 140 and 35 of Item 270. Is this possible. python

• Django: IE doesn't load locahost or loads very SLOWLY

  - by reedvoid

  I'm just starting to learn Django, building a project on my computer, running Windows 7 64-bit, Python 2.7, Django 1.3. Basically whatever I write, it loads in Chrome and Firefox instantly. But for IE (version 9), it just stalls there, and does nothing. I can load up "http://127.0.0.1:8000" on IE and leave the computer on for hours and it doesn't load. Sometimes, when I refresh a couple of times or restart IE it'll work. If I change something in the code, again, Chrome and Firefox reflects changes instantly, whereas IE doesn't - if it loads the page at all. What is going on? I'm losing my mind here....

• Image analysis on the iPhone

  - by user362808

  Hi, guys! Hopefully a quick one. Working on a devious little algorithm that'll automatically scan a user's iPhone for a photo of some emotional poignance (e.g. go back in time a ways, look for one of a group of photos that are proximally timestamped, etc.). Need a quick-and-dirty way of picking out a photo containing two people in close proximity to each other. I know that the OpenCV Python lib [for image processing] works on the iPhone, I'm just curious whether it's actually the best way of doing this (from scratch or otherwise). Cheers!

• Why is this consider bad practice? or is it? (ASP.Net)

  - by user318573

  Would this code be considered bad practice: <div id="sidebar"> <% =DisplayMeetings(12) %> </div> This is a snippet of code from the default.aspx of a small web app I have worked on. It works perfectly well, runs very fast, but as always, I am aware of the fact that just because it works, doesn't mean it is OK. Basically, the DisplayMeetings subroutine outputs a bunch of formatted HTML (an unordered list actually), with no formatting, just the requisite html, and then my CSS performs all the necessary formatting. The data for generating the list comes from an SQL server database (the parameter controls how many rows to return) and I am using stored procedures and datareader for fast access. This keeps my front-end extraordinary simple and clean, imho, and lets me do all the work in VB or C# in a separate module. I could of course use a databound repeater (and probably 6 or more other methods) of accomplishing the same thing, but are they any better? Other than loosing the design-time features of VS2010?

• open program once with multiple files as arguments from explorer

  - by Jonathan

  I have a program that works when, a file is opened with it using the right click menu in explorer. But if I select multiple files and then right click and open with my program then it opens multiple instances of my program, instead of just passing the multiple files as arguments to a single instance. The program is written in vb.net but is not a windows form, it is just a module, so I can to tick the Single instance option in the properties in Visual Studio. So how do I open multiple files from explorer context menu in a single instance.

• Dotnetnuke menu custom root

  - by Yobi21

  Is there anyway to use the built-in DNN Menu module to display a menu based at a different root node other than the current tab node? Given the following structure: Page1 -child1_1 -child1_2 Page3 Page2(hidden) -child2_1 -child2_2 In this scenario I will be having 2 menus on this skin. One will be normal navigation based off of the current node and the other will be a set of 'static' links to pages located outside the current node. When on Page1 the normal navigation will show Page1, Page3 and the children of Page1 nested under Page1. The 'static' links will use 'Page2' as their root and will show child2_1 and child2_2.

• Stocket server crashing with unhandled exception

  - by Rob

  We have a c# (3.5 framework) socket server which is a console app, after about 3000 connections (or less, it's quite random), we get an unhandled exception which crashes the app completely. We're really struggling to find out what's happening and where, the only info we get is below, can anyone shed any light?

• Apache crashes after installing mysqli

  - by Marco P.

  System: Apache 2.2 running on Windows 2008 Server with PHP 5.2.17 VC6 Thread-Safe as a Module and MySQL 5.5.17 - all working fine. After installing mysqli using the php package, Apache won't start anymore. There is no error message in the log. What I have tried: Make sure Windows PATH points to libmysql.dll: Yes, done. Make sure extension_dir points to the right point: Yes. Other extensions load fine. Try without mysqli: Yes, Apache loads fine then. Try without mysql: Yes, does not help. Test mysql itself: Restarts server! Overwrite libmysql: Yes, does not help. It seems to me that there is some general problem with MySql, but the DB server seems to be running fine. I'm really out of ideas of things I could try, so I'm desperate for any hints or tricks.

• Capture variable assignments in a Perl eval

  - by Bruce

  I would like to be able to capture variable assignments from a Perl eval. That is, to determine what variable names have been assigned to within the code and extract their value. For example if I run: eval '$foo=42; $bar=3.14;' The result of the eval is 3.14 (the last value evaluated), but I would also like to be able to determine the names "$foo" and "$bar" and their values (without knowing the names in advance). I have read up on a couple of ways of inserting variables into the eval block, through Safe and Eval::Context, but not yet any way of extracting them. I am more familiar with Python's eval/exec which have built in support for this.

• In a shared .iml file, what should the jdkName be for an IntelliJ IDEA Plugin SDK?

  - by bolinfest

  I work on a team where we commit our .iml files in version control so that everyone can use them. We have an .iml file for a plugin module, which includes the following: <orderEntry type="jdk" jdkName="IDEA IC-117.798" jdkType="IDEA JDK" /> however, that only works for people who are using that version (IC-117.798) of IntelliJ (some are on 12, some are using the ultimate edition, etc.) Is there any sort of variable like $INTELLIJ_SDK that could be used for the value of jdkName so that the .iml file is valid regardless of which version of IntelliJ you are using?

• Kohana 3.2 useradmin routing issue

  - by user1789926

  I am new to kohana and am developing a simple application that is using the useradmin module from http://blog.mixu.net. I am having, what I think, an understanding problem. At present the action_index redirects to user/profile when a non admin user logs in. I want to go to a controller called home instead. I want to redirect to home/index.php I have tried simply changing the redirect and this does not work. I am suspecting I need to do something with routes to get me to home/index but I can not work out what I should be doing. I would really appreciate it if someone could steer me in the right direction here.

We are looking for pluggable component.

• not autolinking all-numeric twitter hashtags in perl?

  - by all_numeric_no_hash

  I'm producing HTML from twitter search results. Happily using the Net::Twitter module :-) One of the rules in Twitter is that all-numeric hashtags are not links. This allows to unambiguously tweet things like "ur not my #1 anymore", as in here: http://twitter.com/natarias2007/status/11246320622 The solution I came up with looks like: $tweet =~ s{#([0-9]*[A-Za-z_]+[0-9]*)}{<a href="http://twitter.com/search?q=%23$1">#$1</a>}g; It seems to work (let's hope), but I'm still curious... how would you do it?

• Count number of results in a View

  - by Jukebox

  I need to count how many people belong in pre-defined groups (this is easy to do in SQL using the SELECT COUNT statement). My Views query runs fine and displays the actual data in my table, but I simply need to know how many results it found. However there doesn't seem to be a COUNT option in views. I am guessing I am going to have to use some sort of views hook, and then stick the result in the table. Here's a quick example of what i'm trying to achieve: My Table ---------------------- Group A | 20 people Group B | 63 people and so on. (I've tried using the Views_Calc module, but I get errors because it is not quite stable yet.) Anybody know of an easy way to count results in Views?

• the problem of redirecting stdout in c#

  Could you please explain why the shell redirection doesn't work with System.Diagnostics.Process class? I am trying to redirect the output streams to file with the following snippet: Process p = new Process(); p.StartInfo = new ProcessStartInfo(); p.StartInfo.FileName = "java.exe"; p.StartInfo.Arguments = @"> c:\Temp\test.log 2>&1"; p.StartInfo.UseShellExecute = true; p.Start(); The similar code works without problems with Python. Reading the output streams programmatically doesn't seem a preferable solution in my case because there will be a bunch of processes launched by my application.
