• One database or many?

  - by dsims

  I am developing a website that will manage data for multiple entities. No data is shared between entities, but they may be owned by the same customer. A customer may want to manage all their entities from a single "dashboard". So should I have one database for everything, or keep the data seperated into individual databases? Is there a best-practice? What are the positives/negatives for having a: database for the entire site (entity has a "customerID", data has "entityID") database for each customer (data has "entityID") database for each entity (relation of database to customer is outside of database) Multiple databases seems like it would have better performance (fewer rows and joins) but may eventually become a maintenance nightmare.

• Generate service layer with Hibernate

  - by gmate

  Hi all! I generate *.hbm.xml mapping files and *.java file from the DB schema, with Hibernate tools. My question is, that is there any option, to generate service classes also? These are the classes where I implement the store(), find(), delete(), etc... methods. I know that for C# there are many solutions to generate almost everything. I'm looking for the same, but with Hibernate. Is there any? Thanks for every reply in advance!

• Can I use breakpoints (as while debugging) while 'unit testing' ?

  - by Richard77

  Hello, I'm walking through the FrontStore series tutorial on TDD in MVC (Part 3 by Rob Conery/ASP.NET). The test I'm concerned with is the CatalogRepository_Each_Category_Contains_5_Products(). Until I get to that test, everything was working fine. Now, I've gone through every line that makes this test (including the test itself, the TestCatalogRepository, ...). I've also compared my code to that of Rob, but the test keeps failing. I also checked the source code from CodePlex, that test was not there. Now, I wonder if I can put a break point somewhere to check the local values as the test is being executed? If not, something similar? Thanks for helping.

• Option Value Changed - ODBC Error 2169

  - by fredrick-ughimi

  Hello, I am connecting to ADS through ODBC DSN. Everything works well until I tried out my Save Routine. Data is saved quite alright but I get an error that says - "Option value changed". What could this be? Can't find in the help file. The full error message is: ODBC - 2169 [iAnywhere Solutions][Advantage ODBC Driver] Option Value Changed. I sent an email in respect of this to [email protected] since this error number falls between error numbers: 2168 - 2188 Internal Error that should be reported. I posted this question on the Newsgroup without a possitive response. Best regards, Fredrick Ughimi [email protected]

• Strange PYTHONPATH problem

  - by DoxaLogos

  I recently updated my python installation to 2.7 (previously 2.5), and I've noticed a strange problem where I cannot import certain modules that I created. I had no problem before. Normally, I edit the PYTHONPATH and add the directory I want to import modules. For some strange reason, I can no longer import. I checked my path in PYTHONPATH, and it looked correct. When I display the sys.path in an interpreter, I see the current directory prepended to every PYTHONPATH entry(i.e. 'c:\blah\blah c:\path\to\module') If I edit the sys.path by appending the directory that I want at the end of the list,everything works fine(i.e. 'c:\path\to\module\'). I never had to do this before. I'm on Windows 7 on two computers. Has anyone else had similar trouble?

• MySQL Group Results by day using timestamp

  - by Webnet

  I need to take the following query and pull the total order counts and sum of the orders grouped by day. I'm storing everything using timestamps. SELECT COUNT(id) as order_count, SUM(price + shipping_price) as order_sum, DAY(FROM_UNIXTIME(created)) as day FROM `order` WHERE '.implode(' AND ', $where).' I need to group by DAY but when I do for this past weekend's sales it takes my order_count and makes it 1 instead of 3. How can I pull the above values grouped by day? NOTE: The implode is used ONLY to define the time period (WHERE created = TIMESTAMP AND <= TIMESTAMP)

• PHP: Display comma after each element except the last. Using 'for' statement and no 'implode/explode

  - by Jonathan

  hi, so I have this simple for loop to echo an array: for ($i = 0; $i < count($director); $i++) { echo '<a href="person.php?id='.$director[$i]["id"].'">'.$director[$i]["name"].'</a>'; } The problem here is that when more than one element is in the array then I get everything echoed without any space between. I want to separate each element with a comma except the last one. I cant use 'implode' so I'm looking for another solution... Anyone?

• sIFR 3 - sifr-config.js possibly not running? Not sure what's wrong.

  - by nukegara

  Hi, I've been messing with this for a few hours, and I just can't get the text to be replaced at all. I really can't believe it's taking so long, especially because I did this a few months ago and got it to work in minutes. Anyway, here is my site I'm working on: http://www.moreheadplanetarium.org/regeneration/test/vision.php and I want to replace the h1 tag (Morehead's Vision). I don't know what's wrong, since I've done everything I know to do. I'm jumping back into web design and using Firebug, and when I check the scripts it only has sifr.js and sifr-debug.js in the list, so I'm assuming the config isn't loading but I have no idea what could be the hold up... How do you get the debug to work btw? thanks!

• Apache mod_rewrite help with Wordpress

  - by protohominid

  I administer my wife's site, namelymarly.com. Up until last week, the root page of the blog was namelymarly.com/blog/. Last week I changed it in the WP settings to be namelymarly.com. WP created the new htaccess file, and I moved the index.php to the root directory (but left the WP folder where it was in the /blog/ directory), as instructed. Everything is working great except for one very important thing: When you type 'namelymarly.com/blog/' into a browser now, you get a 404 error. All other URLs, when they include the '/blog/somethinghere', will redirect properly to '/somethinghere.' It's only when there's nothing after '/blog/' that there's a problem. I tried adding this rule but it breaks the site: RewriteRule ^/blog(/|)$ / Any suggestions/help?

  - by Sef

  Hello, I have a form (with post method) that takes the following input: - a certain name - a number - 3 checkboxes All this input gets generated and calculated in a table.(html code within the php) Everything gets properly calculated and displayed in a table. So my question: How do i make it possible after giving all those input to give in more input? Meaning i have made a hyperlink that goes back to the form itself (where i can give the input). So i can give in new data, and after submiting that again the table now contains 2 rows of values insteed of just 1. Not really sure what exactly i need for this. Regards.

• Entity Framework 4 and 0:1, 0:1 relationships

  - by Eric J.

  I'm using the Model First approach with EF 4 and hit a snag with two tables, Participant (singular because pre-existing from another app) and ActiveParticipants. A Participant may or may not be associated with exactly one ActiveParticipant and vice versa. When I create an association, everything seems to go well on the surface, but then I get a runtime error complaining that Participant does not contain the column ActiveParticipant_Id. It does contain a column ActiveParticipantId (no underscore). When I view the diagram as XML, there's a line like this: <Property Name="ActiveParticipant_Id" Type="uniqueidentifier" Nullable="true" /> Why is it adding an underscore? Is there anything special I need to do for 0:1, 0:1 relationships?

• Why do apps from Android 2.1 stop working with 2.2?

  - by poeschlorn

  Hi guys, I've just updated my nexus one to 2.2. Now all of my (own and some from the market) apps throw exceptions and were closed. It's weird, in the app I'm developing atm, there it displays only my start page with buttons, but when I tap on one button to fire an intent to another activity my app gets closed with an exception. Yesterday before the update everything worked fine. The same thing in my emulator: I have two devices, one with API level 7 and one with level 8. Level 7 worked fine, but level 8 killed my app :( What is the problem and how can I solve this? I'm desperatly trying to get it working again :( I hope someone can help me fixing this

• Shared memory of same DLL in different 32 bit processes is sometimes different in a terminal session

  - by KBrusing

  We have an 32 bit application consisting of some processes. They communicate with shared memory of a DLL used by every process. Shared memory is build with global variables in C++ by "#pragma data_seg ("Shared")". When running this application sometime during starting a new process in addition to an existing (first) process we observe that the shared memory of both processes is not the same. All new started processes cannot communicate with the first process. After stopping all of our processes and restarting the application (with some processes) everything works fine. But sometime or other after successfully starting and finishing new processes the problem occurs again. Running on all other Windows versions or terminal sessions on Windows server 2003 our application never got this problem. Is there any new "feature" on Windows server 2008 that might disturb the hamony of our application?

• QuickTime movie disappearing from Javascript when scrolled offscreen in Firefox?

  - by c-had

  I have a web page I'm creating that uses Javascript to control an embedded QuickTime player. I add the QuickTime movie to the page using the AC_QuickTime.js file from Apple (as described here - http://developer.apple.com/mac/library/documentation/QuickTime/Conceptual/QTScripting_HTML/QTScripting_HTML_Document/ScriptingHTML.html#//apple_ref/doc/uid/TP40001525-2-SW1 ). Everything seems to be working fine - I can call methods on the QuickTime movie and control its playback (as well as get the current timestamp). The problem is that in Firefox, when I scroll down such that the QuickTime player is no longer visible, I get the following error every time I try to call a method on the QuickTime movie: Error calling method on NPObject! This does not occur in Safari. Why is this happening, and is there any way to work around this?

• Shell Prompt Line Wrapping Issue

  - by Rob

  I've done something to break my Bash Shell Prompt in OS X (10.5.7) Terminal. This is the PS1 that I had configured: PS1='\[\e[1;32m\]\h\[\e[0m\]:\[\e[1;34m\]\w\[\e[0m\]\$ ' As far as I can tell I have the color commands escaping correctly. However when I scroll up and down in my command history I often get line wrapping issues if the historic commands wrap onto multiple lines. I simplified my prompts to the following: PS1='\[\e[1m\]\h:\w\$ \[\e[0m\]' PS2='> ' And I still see something like: localhost:~/Library/Application Support/Firefox/Profiles/knpmxpup.Defau lt/extensions/{1A2D0EC4-75F5-4c91-89C4-3656F6E44B68}$ expocd \{1A2D0EC4-7 5F5-4c91-89C4-3656F6E export PS1="\[ \e[1;32m\]\h\[\e[0m\]: cd Library/Appl ication\ Support/ I've also tried \033 instead of \e. I just included PS2 up there for information, I haven't changed that from the install default. If I completely remove the color codes then everything works fine, any ideas?

• Zend_Soap with attachments (server)

  - by Tom

  i'm trying to build a SOAP service with Zend_Soap. Everything is working great but the client needs the ability to send attachments to the service (not base64 encoded strings, as this service will be called multiple times a day with various file sizes so processing all that in memory is not possible. So I'd like to handle a normal SOAP attachment (DIME/MIME) with the SOAP server in Zend Framework however I'm unable to find documentation about it. Can I access it with $_FILES[] or any other way? Is it even possible in Zend_Soap (as there's not that much info available). SOAP is a must - so thanks for the advice but it has to be SOAP, not REST.

• How can I strip non-XHTML tags from a string in C#?

  - by No Average Geek

  I need to be able to remove non-XHTML tags from a string containing XHTML that has been stored in a database. The string also contains references for controls (e.g. ) inside the XHTML, but I need clean XHTML with all standard tag contents unchanged. These control tags are varied (they could be any ASP.NET control), so there are too many to go looking for each one and remove them. The way they are closed is also varied, so not all of them have closing tags, some are self closing. How can I go about doing this? I've found some HTML cleaners on-line for including in my project, but they either remove everything or just HTML encode the entire string. Also, I'm dealing with parts of XHTML documents, not entire documents - don't know if that makes a difference. Any help would be appreciated.

• alias not working on sql server 2008 r2

  - by Saba

  I have several servers with SQL Server 2008 R2 instances on them, and alias doesn't work on any of them. Clients connect to these servers using TCP/IP without any problem, telnet works on IP/Port I use for my alias, the firewall exceptions are created, basically everything works fine, except when I create an alias, I can not connect through it to my server using either TCP/IP or named pipes (local or one of other servers). I've installed latest cumulative updates, which updates native client too (which I think is the source of problem) and I still have the problem. The stranger part is, if I create an alias on a server with sql server 2005 (native client 9), I can connect to my 2008 r2 instances. Any suggestions?

• Odd toString behavior in javascript

  - by George

  I have this small function that's behaving oddly to me. Easy enough to work around, but enough to pique my curiosity. function formatNumber(number,style) { if (typeof style == 'number') { style = style.toString(); } return (number).format(style); } The return format part is based on another function that requires the style variable to be a string to work properly, so I'm just checking if style is a number and if it is to convert it to a string. When the function above is written as is, the format function format doesn't work properly. However when I write it as simply: return (number).format(style.toString()); Everything works. Is there a difference between putting the .toString function inside the format call vs performing it before hand and setting it as the variable style?

• exactly what does rake db:migrate do?

  - by happythenewsad

  Does rake db:migrate only add new migrations, or does it drop all migrations/changes and build everything new? I think rake is throwing an error because it is trying to access a table attribute in migration 040 that was deleted in migration 042. somehow my DB and rake are out of synch and I want to fix them. for you experts out there - is it common for rake to get out of synch with migrations? how can I avoid this (no, I do not hand-edit my schema or rake files).

• Cross version line matching.

  - by BCS

  I'm considering how to do automatic bug tracking and as part of that I'm wondering what is available to match source code line numbers (or more accurate numbers mapped from instruction pointers via something like addr2line) in one version of a program to the same line in another. (Assume everything is in some kind of source control and is available to my code) The simplest approach would be to use a diff tool/lib on the files and do some math on the line number spans, however this has some limitations: It doesn't handle cross file motion. It might not play well with lines that get changed It doesn't look at the information available in the intermediate versions. It provides no way to manually patch up lines when the diff tool gets things wrong. It's kinda clunky Before I start diving into developing something better: What already exists to do this? What features do similar system have that I've not thought of?

• How can I learn Android?

  - by Daisama

  I am a freshman in college which has been Java programming for over a year. I haven taken a couple of programming courses, both of which were with Java. And I have done web development for several years. So overall, I would't say that I am a complete beginner in programming. Recently, I have developed a strong interest in developing for Android. I read that Android development was with Java and I thought it would making development easier for me. But I was very wrong. Based on reviews from Amazon, I have begun reading "Professional Android Application Development by Meier but everything is going over my head. The Busy Coder's Guide to Android Development seems a bit more for my level but I still want everybody else's opinion. The Google stuff isn't very helpful to me at my level and neither are the tutorials on anddev and such. Any advice for a complete beginner on how to get started? Thanks.
