• Using CSS to positon text after an image

  - by Charles L

  I've trying to do something that I'm sure is simple, but I can't do it. All I want to do is have an image and then some text after that image, and be able to control accurately the amount of space between the image and the text. Here's my code: http://pastebin.com/fx17XUaR I couldn't work out how to paste it in here directly. In my style sheet, wrap has these attributes: .wrap { //text-align: left; width: 1100px; height: 870px; background-color: white; color: black; padding: 10px; margin: auto; I want my text to look like this directly below the image: Username Age Location Currently, I just add loads of break tags to control where I have the text, but that's messy and there must be a better way. Thanks in advance for any help.

• possibility to do type/data conversion of data returned by ria services?

  - by reinier

  My service returns an byte array, which I have to convert to an 'animated gif' (using imagetools since silverlight doesn't support it yet) I was wondering, is it possible to insert some code at the client, where I can do the conversion before the actual object is returned to whatever it is binded against? On the server side, the queries can be customized before it is sent over the wire. I'm asking for the exact opposite, can I do some on the fly conversions the moment they get of the wire and before they are returned to the controls. If I'm overthinking this and there is a smarter/better/easier way to do it, I'm all for such an answer as well

• Accessing "current class" from WPF custom MarkupExtension

  - by chaiguy

  I'm attempting to write a custom MarkupExtension to make my life easier by giving me a better way to specify bindings in XAML. However I would like to know if there is any way I can access the object that represents the file the MarkupExtension is used in. In other words, suppose I have a UserControl that defines a particular rendition of a data model of my program. This control has lots of visual stuff like grids, borders and general layout. If I use my MarkupExtension on a particular property of some element in this UserControl, I want to access the instance of the UserControl, without knowing what type it is (I plan on using reflection). Is this at all possible?

• Force reload/refresh when pressing the back button

  - by FlyingCat

  I will try my best to explain this. I have an application that show the 50+ projects in my view page. The user can click the individual project and go to the update page to update the project information. Everything works fine except that after user finish updating the individual project information and hit 'back' button on the browser to the previous view page. The old project information (before update) is still there. The user has to hit refresh to see the updated information. It not that bad, but I wish to provide better user experience. Any idea to fix this? Thanks a lot.

• Check if a symlink has changed

  - by BCS

  I have a daemon that, when it's started, loads its data from a directory that happens to be a symlink. Periodically, new data is generated and the symlink updated. I want a bash script that will check if the current symlink is the same as the old one (that the daemon started with) and if not, restart the daemon. My current thought is: if [[ ! -e $old_dir || $(readlink "$data_dir") == $(readlink "$old_dir") ]]; then echo restart ... ln "$(readlink "$data_dir")" "$old_dir" -sf else echo no restart fi The abstract requirement is: each time the script runs, it needs to check if a symlink on a given path now points to a something other than it did the last time and if so do something. (The alternative would be to check if the data at the path has changed but I don't see that being any cleaner.) My questions: Is this a good approach? Does anyone have a better idea? Where should I put $old_dir?

• Data format for content heavy iPhone app - Plist or XML?

  - by Toby

  Hello, I'm building an iPhone app that is essentially a book, it will be bundled with a lot of text-heavy content. I considered bundling the data as XML and load it when the application starts but the XML would contain a lot of nested structures and be a bit of a pain to parse. Would it be better to use a plist? I'm concerned about memory usage and plists are loaded entirely into memory - can they be parsed in chunks? Is there a maximum size to a plist and how efficient are they? I'm not sure how big the bundled content is going to be yet but I should imagine it could be anywhere from 500k to 4MB. Thanks in advance.

• Why can I create a table with PRIMARY KEY on a nullable column?

  - by AlexKuznetsov

  The following code creates a table without raising any errors: CREATE TABLE test( ID INTEGER NULL, CONSTRAINT PK_test PRIMARY KEY(ID) ) Note that I cannot insert a NULL, as expected: INSERT INTO test VALUES(1),(NULL) ERROR: null value in column "id" violates not-null constraint DETAIL: Failing row contains (null). ********** Error ********** ERROR: null value in column "id" violates not-null constraint SQL state: 23502 Detail: Failing row contains (null). Why can I create a table with a self-contradictory definition? ID column is explicitly declared as NULLable, and it is implicitly not nullable, as a part of the PRIMARY KEY. Does it make sense? Edit: would it not be better if this self-contradictory CREATE TABLE just failed right there?

• User Defined Class as a Template Parameter

  - by isurulucky

  Hi, I' m implementing a custom STL map. I need to make sure that any data type (basic or user defined) key will work with it. I declared the Map class as a template which has two parameters for the key and the value. My question is if I need to use a string as the key type, how can I overload the < and operators for string type keys only?? In template specialization we have to specialize the whole class with the type we need as I understand it. Is there any way I can do this in a better way?? What if I add a separate Key class and use it as the template type for Key? Thank You!!

• When accessing ResultSets in JDBC, is there an elegant way to distinguish between nulls and actual z

  - by Uri

  When using JDBC and accessing primitive types via a result set, is there a more elegant way to deal with the null/0 than the following: int myInt = rs.getInt(columnNumber) if(rs.wasNull())? { // Treat as null } else { // Treat as 0 } I personally cringe whenever I see this sort of code. I fail to see why ResultSet was not defined to return the boxed integer types (except, perhaps, performance) or at least provide both. Bonus points if anyone can convince me that the current API design is great :) My solution was to write a wrapper that returns an Integer (I care more about elegance of client code than performance), but I'm wondering if I'm missing a better way to do this.

• Random numbers from binomial distribution

  - by Sarah

  I need to generate quickly lots of random numbers from binomial distributions for dramatically different trial sizes (most, however, will be small). I was hoping not to have to code an algorithm by hand (see, e.g., this related discussion from November), because I'm a novice programmer and don't like reinventing wheels. It appears Boost does not supply a generator for binomially distributed variates, but TR1 and GSL do. Is there a good reason to choose one over the other, or is it better that I write something customized to my situation? I don't know if this makes sense, but I'll alternate between generating numbers from uniform distributions and binomial distributions throughout the program, and I'd like for them to share the same seed and to minimize overhead. I'd love some advice or examples for what I should be considering.

• Business web application platform structure

  - by VoodooRider

  Hi, I would like to develop a web application in java/spring/hibernate serving as a business platform that I could connect plugins to (i.e. CRM plugin, ware plugin, sales plugin). Those plugins could be dependent of other plugins in a tree manner. The parent project would be packaged as war having all the basic configuration and looks (spring configs, css, scripts), ready to go user and group management, security settings, etc. All together I would like it to behave and look a bit like Joomla, but built using different tools for different purposes. And I have a few questions concerning that project: Do you know of any open source projects offering such a platform ready to go? If not is maven applicable for managing those plugins? What is the best way to package and deploy those plugins? And the last but not least, basically is this the right way to go or is a dead end and it would be better to create a separate web app for those business needs?

• How to name variables which are structs

  - by evilpie

  Hello, i often work on private projects using the WinApi, and as you might know, it has thousands of named and typedefed structs like MEMORY_BASIC_INFORMATION. I will stick to this one in my question, what still is preferred, or better when you want to name a variable of this type. Is there some kind of style guide for this case? For example if i need that variable for the VirtualQueryEx function. Some ideas: MEMORY_BASIC_INFORMATION memoryBasicInformation; MEMORY_BASIC_INFORMATION memory_basic_information; Just use the name of the struct non capitalized and with or without the underlines. MEMORY_BASIC_INFORMATION basicInformation; MEMORY_BASIC_INFORMATION information; Short form? MEMORY_BASIC_INFORMATION mbi; I often see this style, using the abbreviation of the struct name. MEMORY_BASIC_INFORMATION buffer; VirtualQueryEx defines the third parameter lpBuffer (where you pass the pointer to the struct), so using this name might be an idea, too. Cheers

• Converting a PHP array to class variables.

  - by animuson

  Simple question, how do I convert an associative array to variables in a class? I know there is casting to do an (object) $myarray or whatever it is, but that will create a new stdClass and doesn't help me much. Are there any easy one or two line methods to make each $key => $value pair in my array into a $key = $value variable for my class? I don't find it very logical to use a foreach loop for this, I'd be better off just converting it to a stdClass and storing that in a variable, wouldn't I? class MyClass { var $myvar; // I want variables like this, so they can be references as $this->myvar function __construct($myarray) { // a function to put my array into variables } }

• C++ get method - returning by value or by reference

  - by HardCoder1986

  Hello! I've go a very simple question, but unfortunately I can't figure the answer myself. Suppose I've got some data structure that holds settings and acts like a settings map. I have a GetValue(const std::string& name) method, that returns the corresponding value. Now I'm trying to figure out - what kind of return-value approach would be better. The obvious one means making my method act like std::string GetValue(const std::string& name) and return a copy of the object and rely on RVO in performance meanings. The other one would mean making two methods std::string& GetValue(...) const std::string& GetValue(...) const which generally means duplicating code or using some evil constant casts to use one of these routines twice. #Q What would be your choice in this kind of situation and why?

• Hibernate mapping to manage bidirectional relationship using intermediate table

  - by shikarishambu

  I have an object hierarchy that is as follows. Party inherited by Organization and Person Organization inherited by Customer, Vendor Person inherited by Contact In the database I have the following tables Party, Customer, Vendor, Contact. All of them have a corresponding row in Party table. Contact belongs to either Vendor or Customer. I have a field on the Contact table for org_party_id. However, since the organization can be either a Customer or Vendor I need to be able to look at different tables. Is there a way to map this in hibernate? Or, a better way to manage it in DB/ hibernate?

• MySQL::Eliminating redundant elements from a table?

  - by Legend

  I have a table like this: +-------+---------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------+---------+------+-----+---------+-------+ | v1 | int(11) | YES | MUL | NULL | | | v2 | int(11) | YES | MUL | NULL | | +-------+---------+------+-----+---------+-------+ There is a tremendous amount of duplication in this table. For instance, elements like the following: +------+------+ | v1 | v2 | +------+------+ | 1 | 2 | | 1 | 3 | | 1 | 4 | | 1 | 5 | | 1 | 6 | | 1 | 7 | | 1 | 8 | | 1 | 9 | | 2 | 1 | | 4 | 1 | | 5 | 1 | | 6 | 1 | | 7 | 1 | | 8 | 1 | | 9 | 1 | +------+------+ The table is large with 1540000 entries. To remove the redundant entries (i.e. to get a table having only (1,9) and no (9,1) entries), I was thinking of doing it with a subquery but is there a better way of doing this?

• Constructing an if, if else, else statement

  /* Errors exist, have user correct them */ if($form->num_errors > 0) { return 1; //Errors with form } /* No errors, add the new account to the */ else if($database->addLeagueInformation($subname, $subformat, $subgame, $subseason, $subwindow, $subadmin, $subchampion, $subtype)) { $database->addLeagueTable(); $_SESSION['players'] == $subplayers; $comp_name == '$format_$game_$name_$season'; $_SESSION['comp_name'] == $comp_name; return 0; //New user added succesfully } else { return 2; //Registration attempt failed } At the moment this isn't doing any of these things\: $database->addLeagueTable(); $_SESSION['players'] == $subplayers; $comp_name == '$format_$game_$name_$season'; $_SESSION['comp_name'] == $comp_name; Is there a better way to do this?

• Hibernate Annotation for Entity existing in more than 1 catalog

  - by user286395

  I have a Person entity mapped by Hibernate to a database table in a database catalog "Active". After a period of time, records in this database table in the "Active" catalog are archived/moved to an exact copy of the table in a database Catalog "History". I have the need to retrieve from both the Active and History Catalogs. Is there a better way to model this with Hibernate annotations than making an abstract class that 2 classes extend from. This is what I have now. @MappedSuperclass public abstract class Person { @Id private Integer id; private String name; } @Entity @Table(name="Person", catalog="Active") public class PersonActive extends Person { } @Entity @Table(name="Person", catalog="History") public class PersonHistory extends Person { }

• How to efficiently convert DataSet.Tables to List<DataTable>?

  - by Soenhay

  I see many posts about converting the table(s) in a DataSet to a list of DataRows or other row data but I was unable to find anything about this question. This is what I came up with using in .Net 3.0: internal static List<DataTable> DataSetToList(DataSet ds) { List<DataTable> result = new List<DataTable>(); foreach (DataTable dtbl in ds.Tables) { result.Add(dtbl); } return result; } Is there a better way, excluding an extension method? Thanks

• using partials in view helpers

  - by takeshin

  Creating custom Zend View helpers I often end up with something like: // logic here if ($condition) { $output = <<<EOS... } else { $output = <<<EOS... } or using switch. Then to eliminate this, I create setPartial(), getPartial() and htmlize() for using external .phtml's. This is not the best solution, because partials do not support doctype changing. Is there any better solution, than creating abstract class handling this common case? Are there any ready Zend solutions for this case? Separate view helper for each case? And where to put common code?

• Don't panic - there is time!

  - by ripper234

  If you're thinking of moving to Shapado right this instance, take a breath. Yes, I think it's the right move in the long run (be it three months or a year). However, take into consideration that the platform is still not ready. It has bugs and feature-requests that should be fixed. Until they are, you are better off staying with Stack Exchange as long as you can. Of course, it is in your best interest to participate heavily in the 'meta discussion' that takes place at Shapado.com and vote on the features and bug fixes that you want.

• WPF: Creating instances of resources?

  - by oakskc

  I'm brand spanking new to WPF and am trying to play around with projects to better understand what I'm reading. My understanding of a resource is that it is the instance, you can't use it like a factory and create instances of it. For example, a XAML-defined rectangle. You can reference it, but you can't have numerous instances of it all over the surface. In WPF, what would be the way to do that? If I define a Rectangle as a resource with specific properties and wanted to have multiple instances of that within a dynamically-generated grid, how should I be going about it? Or is there a different way I should be trying to do this? Purely academic exercise with no real-world application.

• ASP.NET, Visual Studio and Subversion - how to integrate?

  - by Michael Stum

  I use AnkhSVN and Visual Studio 2005 and 2008. Now, one thing that bugs me is that Ankh does not really work with ASP.NET sites. I cannot add them properly to a repository and it won't detect changes, especially because the site is on a remote server accessed through Frontpage Extensions (File = Open Site). What are the alternatives? Does a better plug-in exist? Manually downloading the files through FTP and using TortoiseSVN or svn.exe is not really the level of integration I want :) I want to stay within the Visual Studio IDE when possible. Also, I do not control the remote Server, so I can not install anything on it, which means the whole change tracking/comparison to repository has to be done on my machine.

• Leaving SQL Management open on the internet

  - by Tim Fraud

  I am a developer, but every so often need access to our production database -- yeah, poor practice, but anyway... My boss doesn't want me directly on the box using RDP, and so we decided to just permit MS SQL Management Console access so that I can do my tasks. So right now we have the SQL box somewhat accessible on the internet (on port 1433 if I am not mistaken), which opens a security hole. But I am wondering, how much of an uncommon practice is this, and what defaults should I be concerned about? We use MSSQL2008 and I created an account that has Read-Only access, because my production tasks only need that. I didn't see any unusual default accounts with default passwords on the system, so I would be interested to hear your take. (And of-course, is there a better way?)

• Reading bytes from JavaScript string

  - by Jan

  I have a string containing binary data in JS. Now I want to read, for example, an integer from it. So I get the first 4 characters, use charCodeAt, do some shifting etc. to get an integer. Problem is that strings in JS are UTF-16 (instead of ASCII) and charCodeAt often returns values higher than 256. The Mozilla reference states that "The first 128 Unicode code points are a direct match of the ASCII character encoding." (what about ASCII values 128?) How can I convert the result of charCodeAt to an ASCII value? Or is there a better way to convert a string of four characters to a 4 byte integer?
