• Application Role and access second database

  - by lszk

  I have written a script to create an audit trails to my database in a second one db. So far I had no problems during tests on my dev machine from SQL Server Management Studio. Problems started to occurs when I first tried to test my triggers from my application by modyfing data in it. Using profiler I found out, that my audit trails db is not visible in sys.databases, so here lies the problem. The application using an Application Role, so as I found on MSDN, that's why I can't get access to other db on the server. I'm not a DBA. I have no experience with properly settings the security stuff, so please guide me, how can I set the setting for guest account (according to MSDN) to get access to this db? I need to have a record for this database in sys.databases and I need to be able to insert data in this database in all tables. No select, update or delete I need.

• How to create a web framework in C# without ASP?

  - by Mark

  I've managed to get a C# asp page running under ubuntu/apache/mono, but I don't want to write my framework in these ASP pages, I want to use straight C# and then I'll use a templating language for my views. But I don't know where to begin? C# is a compiled language, so... how would I do this? Would I compile everything and then have apache hook into the (single) executable and pass in the the request URL? Could I request specific .cs pages and then have apache tell it to compile and then "display" it only if it's been updated? Can the "view" files be compiled individually to avoid having to recompile everything every time there's a change? Is there some "base" I can work from, or am I going to have to reinvent accessing GET and POST variables (by reading header info) and all sorts of other stuff we take for granted in languages like PHP?

• Is it good practice to export variables in Perl?

  - by gvkv

  I'm finding it very convenient to pass configuration and other data that is read or calculated once but then used many times throughout a program by using Perl's use mechanism. I'm doing this by exporting a hash into the caller's namespace. For example: package Myconfiguration; my %config; sub import { my $callpkg = caller(0); my $expsym = $_[1]; configure() unless %config; *{"$callpkg\::$expsym"} = \%config; } and then in other modules: use MyConfiguration (loc_config_sym); if ( $loc_config_sym{paramater} ) { # ... do stuff ... } However, I'm not sure about this as a best practice. Is it better to add a method that returns a hash ref with the data? Something else?

• Are there viable alternatives for Web 2.0 apps besides lots of Javascript?

  - by djembe

  If you say find C-style syntax to be in the axis of evil are you just hopelessly condemned to suck it up and deal with it if you want to provide your users with cool web 2.0 applications - for example stuff that's generally done using JQuery and Ajax etc? Are there no other choices out there? We're currently building intranet apps using pylons and a bunch of JavaScript along with a bit of Evoque. So obviously for us the world would be a better place if instead something equivalent existed written in like PythonScript. But I've yet to seen anything approaching that aside from the Android system's ASE - but obviously that's something rather unrelated. Still - if browsers could support other scripting languages....

• Htaccess/robots.txt to allow search bots to explore main domain but not directory on other domain

  - by gX

  Ok, I understand the Title didn't make any sense so here I've tried to explain it in detail. I'm using a hosting that gives me space for my domain and lets me "add on" other domains on it. So lets say I have a domain A, and I add on a domain B. Basically my hosting gives me a public_html where I can put stuff that shows when someone visits website A. But, when I add the domain B, it lets me put the content of B, INSIDE of that public_html so that website B.com can also be visited by going to A.com/siteB... Thats all good, except that Google has started indexing B.com as well as A.com/siteB, I'm ok with it indexing B.com, but I somehow want to prevent it from indexing A.com/siteB so that when people search for B, it doesn't end up showing A.com/siteB. Any ideas? Let me know if the question is still unclear.

• jquery specific show buttons on hover

  - by bob

  I have an application creating a bunch of divs through a loop. Each div has the class "product" so it looks like <div class="product"> !.....stuff here ....! <div class="show_on_hover">...buttons here... </div> </div> so there are about 12 of these same divs per page. I would like to hover over a specific one and show the specific "show_on_hover" div which is initially set to display:none. $('.product').hover(function() { $(.show_on_hover).show(); }, function () { $(.show_on_hover).hide(); } ); That is what I have so far but it will show ALL of the .show_on_hovers on the page so I am wondering how to get only the specific one you have moused over to show. This effect is seen on youtube when you mouseover any of the comments, and some comment tools pop up. Thanks!

• Consistency in placing operator functions

  - by wrongusername

  I have a class like this: class A { ...private functions, variables, etc... public: ...some public functions and variables... A operator * (double); A operator / (double); A operator * (A); ...and lots of other operators } However, I want to also be able to do stuff like 2 * A instead of only being allowed to do A * 2, and so I would need functions like these outside of the class: A operator * (double, A); A operator / (double, A); ...etc... Should I put all these operators outside of the class for consistency, or should I keep half inside and half outside?

• Squid+iptables: how do i allow https to pass-through and bypassing Squid?

  - by logansama

  Hello, Basically started with Squid and iptables today (google is your friend). This stuff is going to be the death of me. I have Squid3 setup on Ubuntu 9.04 server as Transparent Proxy. It works sweetly when i use the proxy-box as my default gateway etc. The iptable rules for this setup was part of the tutorial. :P I can unfortunately not access https sites (such as Gmail or anything on port 443 basically). This is because Squid dont like what it cannot cache, which in this case is the https traffic. I would like to add an iptable rule so that i can basically access https sites and use Skype. Basically allow these types of traffic to pass through without going through Squid proxy? (bypassing it so to speak) Would anyone perhaps know how to do this or have a link to any sources that would assist me in figuring it out? Thank you.

• MySQL Returns wrong values on SELECT statement

  - by Andrew K

  All, I'm wondering if this is a MySQL bug, but since I've seen others playing with larger numbers than this, I'm thinking I'm doing something wrong here. Here is my table structure for the table I'm querying: mysql describe ipspace6\G ************* 1. row ************* Field: id Type: decimal(39,0) unsigned Null: NO Key: Default: NULL Extra: ************* 2. row ************* Field: addr Type: decimal(39,0) unsigned Null: NO Key: PRI Default: 0 Extra: ************* 3. row ************* Field: netmask Type: decimal(39,0) unsigned Null: NO Key: Default: 0 Extra: ************* 4. row ************* Field: subnet Type: int(4) Null: NO Key: Default: NULL Extra: Now, I run a simple SELECT statement against the "id" column: mysql SELECT id FROM ipspace6 WHERE id='50552019118453823914642686339427860480'; +----------------------------------------+ | id | +----------------------------------------+ | 50552019118453823730175245602332344320 | | 50552019118453823730175245602332344320 | | 50552019118453823914642686339427860480 | | 50552019118453823914642686339427860480 | +----------------------------------------+ ...What the heck is going on here? Two of these results are valid, and two definitely are not. It's not like I'm doing some super-complex nested query or anything, this is simple stuff, and it's driving me insane. Help, anyone?

• Java import from other directory

  - by heldopslippers

  Hi People! I am building a Enterprise Service Bus (ESB) with Java. I won't get into details But I have to build multiple servers who make use of the same classes. I have the following directory structure: /server1 -Main.java /server2 -Main.java /com -Database.java I want to import from the Main.java class for example the Database.class. But of course the following statements won't work: import com.Database; I am working with the javac compiler in the command line (so not eclipse stuff or whatever. just TextMate and the command line). And I found a (pretty stupid) solution by creating a symbolic link in the servers to the com directory. But that is not really an ideal solution. Does anybody have a better one?? THANXS in advanced!! :D

• Calling a method on a Object says "disallows late binding"

  - by Maury Markowitz

  I have a calls called DtaDate that stores an integer "key", a string name, a string for the date, and a Date object that is created from that string. I have some code that needs to accept a date-like object. I'd like the user to be able to pass in anything date like - a Date object which I'll extract the information from, another DtaDate, a string with the date in it, or even the key, which I'll use to look up the DtaDate from a collection. So I have this: Friend Sub New(NameIn As String, DateFormulaIn As String, Optional FromDateIn As Object = Nothing) [stuff that works] [check that we got a FromDateIn...] If TypeOf FromDateIn Is DtaDate Then fdk = FromDateIn.Key Ans.FromDate = fdk VB tells me that "Option Strict On disallows late binding". The other cases, where a string or integer is the TypeOf, I use CInt or CStr. But this is the first time I've actually run into a case where the casting is a non-base type. What's the trick?

• Dollar sign and/or Dash breaking Razor's parser

  the end-result i'm trying to render: <input type="radio" name="options" id="options_1" />$1 - A Not Very Expensive Chocolate <input type="radio" name="options" id="options_2" />$10 - A Kinda Expensive Chocolate <input type="radio" name="options" id="options_3" />$100 - A Really Expensive Chocolate From this code: @foreach (var o in Model.Options){ <input type="radio" name="options" id=@("options_" + @o.ID) />[email protected] - @o.Label } If i drop both the '$' and the '-' from what should be plain old text - stuff works. Adding either resulted in compiler warnings and runtime errors. I've tried the explicit syntax as described here but haven't found the right combination yet.

• could you build Stackoverflow with Drupal 7?

  - by ajsie

  im wondering if one can/should build a site like Stackoverflow with Drupal 7? we all know what Stackoverflow is and how it looks like. users <- threads <- tags and the openid stuff, validation etc. if you are going to build a site exactly as SO, will you use Drupal 6/7 or a MVC framework like CakePHP, CodeIgniter...? try to be realistic here and think about the actual work to do and how to implement with or without Drupal, not just "Drupal has nice features you can use and extend". would be helpful. thanks!

• The D Programming Language for Game Development

  - by n2liquid

  Hi all, Recently I've been bothered because I reached a point in which C++ (even 0x) felt very limited, so I started looking for alternatives. Forget Java, C#, Python or Ruby. I still like the low-level nature of C++ and I'm not fond of virtual machines. Further, I'm a game engine developer, so I have to develop core routines which must be really fast, and lately I've been hungry for code expressiveness. C++ is an almost-there language for me, but there are many exceptions on how to use templates, and GCC isn't optimizing stuff as well as I'd hoped it would. So I'm considering to start learning D. Do you think it will suffice my needs as a game developer? I'm weary because I've never heard of D being used for that. Thanks!

• Normalized Device Coordinates to window coordinates

  - by okoman

  I just read some stuff about the theory behind 3d graphics. As I understand it, normalized device coordinates (NDC) are coordinates that describe a point in the interval from -1 to 1 on both the horizontal and vertical axis. On the other hand window coordinates describe a point somewhere between (0,0) and (width,height) of the window. So my formula to convert a point from the NDC coordinate system to the window system would be xwin = width + xndc * 0.5 * width ywin = height + ynfv * 0.5 * height The problem now is that in the OpenGL documentation for glViewport there is an other formula: xwin = ( xndc + 1 ) * width * 0.5 + x ywin = ( yndc + 1 ) * height * 0.5 + y Now I'm wondering what I am getting wrong. Especially I'm wondering what the additional "x" and "y" mean. Hope the question isn't too "not programming related", but I thought somehow it is related to graphics programming.

• Java Thread Message Passing

  - by pkulak

  I'm writing an Android app. I have a main method, which creates and runs a new Thread using an anonymous inner Runnable class. The run() method, when it's done, calls a method on it's parent class (in the main thread) that calls notifyDataSetChanged() so that the main thread can redraw the new data. This is causing all kinds of trouble (ViewRoot$CalledFromWrongThreadException). The thing is, this method being called from the worker thread is on the class that's created in the UI thread. Shouldn't that be running on the UI thread? Or am I missing something? Here's some code about what I'm talking about: public class Mealfire extends Activity { @Override public void onCreate(Bundle icicle) { (new Thread() { public void run() { // Do a bunch of slow network stuff. update(); } }).start(); } private void update() { myAdapter.notifyDatasetChanged(); } }

• send javaScript variable to php variable

  - by mrbunyrabit

  First i thought that i had to convert javascript to php, but then i found out that cant because of server and client side executions. So now I simply want to send ONE variable <script type="text/javascript"> function scriptvariable() { var theContents = "the variable"; } </script> to a php variable <?php $phpvariable ?> That function in the javascript executes when lets say i click on a button. Now i have Nooo idea how to get that phpvariable Equal to the javascript one so i can use that phpvariable to look up stuff in my Database. I know i can add it to my url or some thing, and just refresh the page.. But id like to do it with AJAX as further in my webpage i might have to use this Ajax method.. So is there an easy way to do this without having to dump pages of code on my page to do one simple thing?

• iPhone app -- are plists the way to handle default values and other languages?

  - by d_CFO

  I wrote my first program almost fifty years ago (yes, coding is still a blast, managing big projects with many programmers was not), but my Von Neumann thinking gets in the way. I want to (a) load default values and (b) account for multiple languages more elegantly (?) than 60-plus iterations of NSLocalizedString. Can I park all of this data into what amounts to a record with fields like this: (key value stuff), (tweak-able user prompt / screen name / whatever), (tasteful default), (user-supplied value)? NSUserDefault has worked well so far; Core Data looks like overkill (?), and sql lite, well, where's Oracle when you need it?

• No optimization causes wrong search result

  - by KailZhang

  I just took over our solr/lucene stuff from my ex-colleague. But there is a weird bug. If there is no optimization after dataimport, actually if there are multiple segment files, the search result then will be wrong. We are using a customized solr searchComponent. As far as I know about lucene, optimization is only optimization which could improve the speed of indexing and should not affect search result. I doubt this may be related to multithreading or unclosed searcher/reader or something. Anybody can help? Thank you.

• Is there any way to get Visual Studio 2008 to update .net style comments automatically?

  - by Jon Cage

  I've been writing a lot of VC++ 2008 / CLI software recently and am using the C#/CLI style documentation: /// <summary> /// Function the does stuff /// </summary> /// <param name="someParam">Specifies some option</param> /// <returns>true if it worked</returns> bool DoStuff( bool someParam ); I find myself re-typing those blocks quite frequently and frankly, it's getting repetitive. Is there any way to get Visual Studio to create / update those blocks automatically as you create new function definitions or update existing definitions?

• Running CodeIgniter cron on localhost

  I'm trying to get a cron job to run every 5 min on my localhost. Using the Cronnix app I entered the following command 0,5 * * * * root curl http://localhost:8888/site/ > /dev/null The script runs fine when I visit http://localhost:8888/site/ in my browser. I've read some stuff about getting CI to run on Cron, using wget and various other options but none make a lot of sense. In another SO post I found the following command wget -O - -q -t 1 http://www.example.com/cron/run What is the "-O - -q -t 1" syntax exactly? Are there other options?

• jQuery works on local host, but not on website

  - by Cortopasta

  Using Notepad++ and XAMPP to test stuff, then I upload it to the website over FTP. In the head of my code, I have this to call jQuery and the script: <script type="text/javascript" src="/jquery.js"></script> <script type="text/javascript" src="/portfolio.js"></script> and it works fine locally on my XAMPP server. But as soon as it's uploaded onto the host, it throws this error: Resource interpreted as script but transferred with MIME type text/html. Not sure what's going on, or why it's having a hard time using jQuery. Any ideas?
