• CSS line wrapping

  - by Mic

  Given a block container <div> this is a very long string which contains a bunch of characters that I want to break at container edges. </div> are there any css properties I can set to force it to break when it reaches the container width, regardless of the contents of the string, for example a break like: this is a ve ry long stri ng which ... is pretty much what I want. Right now, it seems to always prefer to break at whitespace characters or other special characters (such as /).

• "Access is denied" error on accessing iframe document object

  - by Ovesh

  For posting AJAX forms in a form with many parameters, I am using a solution of creating an iframe, posting the form to it by POST, and then accessing the iframe's content. specifically, I am accessing the content like this: $("some_iframe_id").get(0).contentWindow.document I tested it and it worked. On some of the pages, I started getting an "Access is denied" error. As far as I know, this shouldn't happen if the iframe is served from the same domain. I'm pretty sure it was working before. Anybody have a clue? If I'm not being clear enough: I'm posting to the same domain. So this is not a cross-domain request. I am testing on IE only. P.S. I can't use simple ajax POST queries (don't ask...)

• sql server datetime

  - by cvista

  hey i have the following query: select * from table where table.DateUpdated >='2010-05-03 08:31:13:000' all the rows in the table being queried have the following DateUpdated: 2010-05-03 08:04:50.000 it returns all of the rows in the table - even though it should return none. I am pretty sure this is because of some crappy date/time regional thing. if i swap the date to be select * from table where table.DateUpdated >='2010-03-05 08:31:13:000' then it does as it should. How can i force everything to be using the same settings? this is doing my head in :) This is sql generated by NHIbernate from my WCF service if that matters. w://

• Dealing w/ Sqlite Join results in a cursor

  - by Bill

  I have a one-many relationship in my local Sqlite db. Pretty basic stuff. When I do my left outer join I get back results that look like this: the resulting cursor has multiple rows that look like this: A1.id | A1.column1 | A1.column2 | B1.a_id_fk | B1.column1 | B1.column2 A1.id | A1.column1 | A1.column2 | B2.a_id_fk | B2.column1 | B2.column2 and so on... Is there a standard practice or method of dealing with results like this ? Clearly there is only A1, but it has many B-n relationships. I am coming close to using multiple queries instead of the "relational db way". Hopefully I am just not aware of the better way to do things. I intend to expose this query via a content provider and I would hate for all of the consumers to have to write the same aggregation logic.

• How do I start using Linux for web development?

  - by Chris Maple

  OK, so that's maybe not the best title, but I don't know exactly what I want to do, so, please, hear me out. I've used Windows pretty much all my life although I played with Linux on several occasions. At work everyone does web development with php on Windows using the same IDE and stuff. I would like to experience the powerful Linux command line as well as test my web apps locally running the Linux version of php, however I prefer to keep using the IDE because I feel that version control, FTP, code completion etc. are helpful to my productivity. Eventually I would also like to dive into Ruby and Python and I hear that they're not really suited for Windows users. Is running a Linux distro in a virtual machine my best bet? Should I try something like Wubi (Ubuntu running inside Windows)? Or are there any other options out there?

• Drupal: I cannot connect to the database.. please help

  - by Patrick

  hi, I've hard time to make Drupal work on IIS Microsoft server. I've succesfully run Joomla on the same server so I'm pretty sure the following information are correct: host: localhost user: user pass: pass databaseName = servername_databasename I've set the following line in settings.php file: $db_url = 'mysql://user:password@localhost/servername_databasename'; but what I get is this: If you are the maintainer of this site, please check your database settings in the settings.php file and ensure that your hosting provider's database server is running. For more help, see the handbook, or contact your hosting provider. I don't get any other error message such as: database doesn't exist, user/pass wrong.. just this. The database is running, I can access with phpmyadmin. I've tried both "mysql" and "mysqli". The host is a private server (IIS Microsoft), the database is Mysql The database and website files upload have also been succesfull.. so I dunno what to do to fix this issue. thanks

• How to create a tree with filtered nodes from drupal taxonomy.

  - by sprugman

  I'm trying to create a menu tree in drupal like this: - term 1 node 1 node 2 - sub-term 1 node 3 node 4 + sub-term 2 - sub-term 3 node 5 - sub-sub-term 1 node 6 + term 2 etc. (Sub-term 2 and term 2 are toggled closed.) Some requirements: Output this using something like JQuery Menu to get an interactive tree Filter the nodes by cck type Filter the nodes by cck field Only have terms with nodes or other active terms in them show up Mark the current node as such, and automatically open the tree to that point Do I have to write this myself, or are there a combination of modules that can do it? I've got Advanced Taxonomy Blocks, which is pretty close, but it doesn't list the nodes.

• Trying to understand MVC Models, Advice?

  - by Tyler

  I am writing my own MVC for the purpose of learning it. I have pretty much everything "down-pat" and my main stuff written besides models due to some trouble understanding them and lack of viable examples. Now, I've been told a model should reprecent a single row, someone told me, your model class should on update/insert and delete rows, anything that involves fetching a single or multiple rows - a "finder" class should be used. So... a) what is a finder class, b) how do I implement it in a useage example, c) Is what I've been told about models correct or is there a better way than "finders"? Advice is much appricated :)

• VB.NET: Scrollbar "button"?

  - by Omega

  I plan on using a scrollbar for, well, scrolling an image. The image is 200x500, however, the only visible area is 200x250. So I set the max value to 250, and the min value to 0. The idea is that if I drag the scrollbar's button to the bottom, 250 pixels will have moved for the image, right? But wait, the scrollbar's button is.... very small. And the scrollbar is actually pretty long. Is there a way to make the scrollbar's button longer?

• iphone Memory gets freed in debug mode but not in release mode

  - by gdr

  I have been testing my iPhone debug build on both my device and simulator with activity monitor, leaks, and object allocations. The code is pretty well optimized so I have decided to test the release build. I went into the project Menu and set the target build to be release, I then added the necessary header paths that my app is using to the headers search paths and ran the release build on the device with the above mentioned instruments. What I have noticed now is that memory that was freed when I used the debug build does not get freed when using release version. There is one place in my App that I remove a scroll view with some images which frees up a significant amount of memory when I use the debug build, but no memory is freed up in that place when I use the release version. Does someone have any ideas where I need to start looking at? did I setup my release build wrong?

• Python Beginner: Selective Printing in loops

  - by Jonathan Straus

  Hi there. I'm a very new python user (had only a little prior experience with html/javascript as far as programming goes), and was trying to find some ways to output only intermittent numbers in my loop for a basic bicycle racing simulation (10,000 lines of biker positions would be pretty excessive :P). I tried in this loop several 'reasonable' ways to communicate a condition where a floating point number equals its integer floor (int, floor division) to print out every 100 iterations or so: for i in range (0,10000): i = i + 1 t = t + t_step #t is initialized at 0 while t_step is set at .01 acceleration_rider1 = (power_rider1 / (70 * velocity_rider1)) - (force_drag1 / 70) velocity_rider1 = velocity_rider1 + (acceleration_rider1 * t_step) position_rider1 = position_rider1 + (velocity_rider1 * t_step) force_drag1 = area_rider1 * (velocity_rider1 ** 2) acceleration_rider2 = (power_rider2 / (70 * velocity_rider1)) - (force_drag2 / 70) velocity_rider2 = velocity_rider2 + (acceleration_rider2 * t_step) position_rider2 = position_rider2 + (velocity_rider2 * t_step) force_drag2 = area_rider1 * (velocity_rider2 ** 2) if t == int(t): #TRIED t == t // 1 AND OTHER VARIANTS THAT DON'T WORK HERE:( print t, "biker 1", position_rider1, "m", "\t", "biker 2", position_rider2, "m"

• where should I put the EF entity and data annotations in asp.net mvc + entity framework project

  - by giddy

  So I have a DataEntity class generated by EntityFramework4 for my sqlexpress08 database. This data context is exposed via a WCF Data Service/Odata to silverlight and win forms clients. Should the data entities + edmx file (generated by EF4) go in a separate class library? The problem here then is I would specify data annotations for a few entities and then some of them would require specific MVC attributes (like CompareAttribute) so the class library would also reference mvc dlls. There also happen to be entity users which will be encapsulated or wrapped into an IIdentity in the website. So its pretty tied to the mvc website. Or Should it maybe go in a Base folder in the mvc project itself? Mostly the website is data driven around the database, like approve users, change global settings etc. The real business happens in the silverlight and win forms apps. Im using mvc3 rc2 with Razor. Thanks

• How does jQuery .data() work?

  - by kazanaki

  My Javascript knowledge is pretty limited. Instead of asking several javascript questions I got the "message" from Stack overflow and started using jQuery right away in order to save me some time. However several times I do not undestand the "magic" behind jQuery and I would love to learn the details. I want to use .data() in my application. The examples are very helpful. I do not understand however WHERE these values are stored. I inspect the webpage with Firebug and as soon as .data() saves an object to a dom element, I do not see any change in Firebug (either HTML or Dom tabs). I tried to look at jQuery source, but it is very advanced for my Javascript knowledge and I lost myself. So the question is: Where do the values stored by jQuery.data() actually go? Can I inspect/locate/list/debug them using a tool?

• Which are the most important media queries to use in creating mobile responsive design?

  - by Matt

  There are a lot different media queries for mobile screen sizes. It can be overwhelming to accomodate all of them when designing a responsive mobile site. Which are the most important ones to use when designing for mobile? I found this article that does a pretty good job of outlining the available media queries: http://css-tricks.com/snippets/css/media-queries-for-standard-devices/. /* Smartphones (portrait and landscape) ----------- */ @media only screen and (min-device-width : 320px) and (max-device-width : 480px) { /* Styles */ } /* Smartphones (landscape) ----------- */ @media only screen and (min-width : 321px) { /* Styles */ } /* Smartphones (portrait) ----------- */ @media only screen and (max-width : 320px) { /* Styles */ } /* iPads (portrait and landscape) ----------- */ @media only screen and (min-device-width : 768px) and (max-device-width : 1024px) { /* Styles */ } /* iPads (landscape) ----------- */ @media only screen and (min-device-width : 768px) and (max-device-width : 1024px) and (orientation : landscape) { /* Styles */ } /* iPads (portrait) ----------- */ @media only screen and (min-device-width : 768px) and (max-device-width : 1024px) and (orientation : portrait) { /* Styles */ } /* Desktops and laptops ----------- */ @media only screen and (min-width : 1224px) { /* Styles */ } /* Large screens ----------- */ @media only screen and (min-width : 1824px) { /* Styles */ } /* iPhone 4 ----------- */ @media only screen and (-webkit-min-device-pixel-ratio : 1.5), only screen and (min-device-pixel-ratio : 1.5) { /* Styles */ }

• Selecting contents of Label Control

  - by j-t-s

  Hi All I have what I consider to be a pretty unique problem here, and no idea how to implement. From what I've seen, there is no documentation, tutorials, samples and/or articles on this. I've spent weeks researching, with nothing to show. The problem: I need the user to be able to select the contents of a Label Control at runtime, and edit it. If this can be done by extending the existing Label control, great! Or, if this requires a whole new Label Control to be created, fine. So be it. Using a TextBox is not an option I'm afraid. Any help at all is greatly appreciated! Thank you, jase

• AJAX with Ruby on Rails?

  - by Zachary

  This is probably a really dumb question with a simple answer but... I am working on a project where I need to use AJAX to send/receive information. I am using Ruby on Rails (which I am pretty new to), but rather than using the helper methods or the built in functionality in the 'defaults' Javascript file, I need to do this manually in my own Javascript. I believe that ultimately I will want to send a request with a JSON object, then have the controller return another JSON object containing the requested information. The problem is that I cannot seem to find the syntax for sending something to a specific controller method, with parameters, directly from Javascript - everything I Google ends up being tutorials for using the Rails AJAX helper methods.

• Connection to DB2 in Python

  - by Mestika

  Hi, I'm trying to create a database connection in a python script to my DB2 database. When the connection is done I've to run some different SQL statements. I googled the problem and has read the ibm_db API (http://code.google.com/p/ibm-db/wiki/APIs) but just can't seem to get it right. Here is what I got so far: import sys import getopt import timeit import multiprocessing import random import os import re import ibm_db import time from string import maketrans query_str = None conn = ibm_db.pconnect("dsn=write","usrname","secret") query_stmt = ibm_db.prepare(conn, query_str) ibm_db.execute(query_stmt, "SELECT COUNT(*) FROM accounts") result = ibm_db.fetch_assoc() print result status = ibm_db.close(conn) but I get an error. I really tried everything (or, not everything but pretty damn close) and I can't get it to work. I just need to make a automatic test python script that can test different queries with different indexes and so on and for that I need to create and remove indexes a long the way. Hope someone has a solutions or maybe knows about some example codes out there I can download and study. Thanks Mestika

• HTML/CSS Div placing

  - by Andreas Carlbom

  Yo. There's a tendency in placing divs to follow each other vertically, but what i'm trying to accomplish right now is to is basically to place a number of divs (two) inside a parent div like so: <div id='parent'><div id='onediv'></div> <div id='anotherone'></div> </div> And i'd like to place 'anotherone' just to the right of 'onediv'. Sadly, float:right is pretty much ruining the layout with the divs popping out of their parent divs and whatnot. Any suggestions are welcome. Edit: It might be worth noting that the parent div and 'anotherone' has no height elements at all, with 'onediv' planned to be thought as the "height support" div, allowing the contents of 'anotherone' to make the parent div larger at will.

• TStringGrid with BOTH editing AND range selection?

  - by Kevin Killion

  Question: Can anyone point to an article or code samples anywhere on how to provide BOTH editing AND range selection in a TStringGrid? Yes, I KNOW there are third-party grids that do this, but it's frustrating that the built-in grid lacks this basic capability. Background: It's pretty normal to expect to be able to both edit a cell in a grid, and also to select a range of cells such as for a Copy operation. As delivered, TStringGrid doesn't do that. It's either/or. In fact, the docs tell us about the grid Options, "When goEditing is included in Options, goRangeSelect has no effect". However, it looks like it may be possible to do editing and rangeselects in a TStringGrid anyway!!! Through careful use of the mousedown, mouseup, selectcell and exit events, you can get dang close by switching editing elements on and off at the right times. But I still don't have it perfect, and that only covers mouse use, not keyboard changes.

• (My)SQL performance: updating one field vs many unneccesary fields

  - by changokun

  i'm processing a form that has a lot of fields for a user who is editing an existing record. the user may have only changed one field, and i would typically do an update query that sets the values of all the fields, even though most of them don't change. i could do some sort of tracking to see which fields have actually changed, and only update the few that did. is there a performance difference between updating all fields in a record vs only the one that changed? are there other reasons to go with either method? the shotgun method is pretty easy...

• What's the best way to clear the slate with your team

  - by Jonathan

  I work largely as an architect, and have developed a pretty big enterprise application based on SOA. Turns out my teamleader has been skilling up the indians behind my back even though I've been spending time and effort preparing a formal handover (to describe the design decisions and why). It just breeds lack of trust and sends the wrong message about the value of my work. Now I'm too furious to even talk to anyone. Do I sit in silence for the next 3 weeks waiting for my transfer?

• What are the common issues that can cause slow boot times of Windows CE6 Images?

  - by Psychic

  I am relatively new to Platform Builder, and whilst I am able to produce nk.bin files, they boot very slowly, 80-100 seconds, so I think there may be some checkbox somewhere that I need to set (or clear)! I've already removed kitl, profiling, etc in the project settings, and set the project to 'release build' & 'ship'. When I looked at the startup event log (in debug), there doesn't appear to be any specific point where it is slow. The log pretty much scrolls all the way through with no major pauses. One thing I found strange was that although the nk.bin file was a lot smaller in release build (just under 12Mb), the boot time didn't noticeably change from the debug build... The board is a Vortex86DX_60A and I'm building CE6. Are there any 'common builder mistakes' that I may be missing here, or is this going to be something a little deeper?

• How to index a string like "aaa.bbb.ddd-fff" in Lucene?

  - by user46703

  Hi, I have to index a lot documents that contain reference numbers like "aaa.bbb.ddd-fff". The structure can change but it's always some arbitrary numbers or characters combined with "/","-","_" or some other delimiter. The users want to be able to search for any of the substrings like "aaa" or "ddd" and also for combinations like "aaa.bbb" or "ddd-fff". The best I have been able to come up with is to create my own token filter modeled after the synonym filter in "Lucene in action" which spits out multiple terms for each input. In my case I return "aaa.bbb", "bbb.ddd","bbb.ddd-fff" and all other combinations of the substrings. This works pretty well but when I index large documents (100MB) that contain lots of such strings I tend to get out of memory exceptions because my filter returns multiple terms for each input string. Is there a better way to index these strings?

• Increased kerning on website text

  - by Bradley Herman

  We're developing a site for a client right now and my boss (designer only) is once again making me increase letter-spacing on the text so that it looks 'prettier'. I am of the firm belief that this often causes eye-strain and hinders readability in body copy, but being the boss, she is of course always 'right' until I can provide her with examples showing why she's wrong (generally pretty easy). In this case, however, I can't find any articles talking about eye-strain and kerning, so I figured I'd ask what you guys think about the issue of increased letter-spacing in web text. Take a look at http://sparktoignite.com/allograft/process.php and tell me how you feel about the body copy. We're using font-embedding, so you'll only see the proper font in FF, Safari, and Chrome. Let me know what you guys think about the readability and eye-strain caused by the font. My boss currently thinks it's 100% perfect (she wanted the kerning increased further, but I talked her down luckily).

• How stable or unstable is symfony 2.0 ?

  - by Doron

  Well, I know it's a preview, and I know it says that it's not yet ready for production, and yet I dare ask the question. I need to start building a pretty big application, which is planned to go live at around sep-oct 2010. Lets say I will not release the application to production until the stable version of symfony 2.0 will be released - is it a good idea (well, I'll settle for a viable idea) for me to start building the application using the 2.0 version ? How big is the chance I will need to rewrite/replace code I've written due to core changes in the framework ? Thanks. Edit: the other option right now, is to use symfony 1.4. I have thought and tried Zend Framework, but I refuse to re-invent each and every module, which will cost me a lot of programming hours (if not days/weeks).
