• formatting and converting in java

  - by mike_hornbeck

  I have few small basic problems : How to format : int i = 456; to give output : ""00000456" ? I've tried %08d but it's not working. Next thing is a problem with conversion and then formatting. I have side and height of triangle, let's say int's 4,7, and 7 is the height. From formula for field we know that F=1/2(a*h). So how to get F as float, with precision up to 10 places ? float f = a*h; works fine, but multiplying it by 0.5 gives error and by 1/2 returns 0.

• What pattern is this? php

  - by user151841

  I have several classes that are basically interfaces to database rows. Since the class assumes that a row already exists ( __construct expects a field value ), there is a public static function that allows creation of the row and returns an instance of the class. Here's an example ( without the actual database inserts ): class selfStarter { public $type; public function __construct( $type ) { $this->type = $type; } public static function create( $type ) { if ( ! empty($type) ) { $starter = & new selfStarter($type); return $starter; } } } $obj1 = selfStarter::create( "apple" ); $obj2 = & new selfStarter( "banana" ); What is this pattern called?

• Need guidance for my first Android application: how many activities should I use?

  - by jul

  Hi, I'm starting Android doing an application for searching restaurants, and some guidance would be welcome! On the first screen I'd like to have a search field with a submit button (I get the data from a web service), and below a list with the results of the search. When clicking on one of the items of the list it will show a screen with the restaurant details as well as a map showing its location. My questions are: Can I do everything in one single activity or should I do an activity for the search, one for the result list, one for the restaurant description, and another for the map? Would doing one single activity make the application more responsive? How can I use a list and a map within a normal activity (without ListActivity and MapActivity)? Any help, pointer, example application or sample code is very appreciated! Thank you Jul

• Search for all instances of certain annotation type

  - by user1064918

  Suppose I have this annotation @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.FIELD) public @interface Name { String value(); } This is going to be used as follows @Name("name1") public static Foo foo = new Foo(); I have multiples of these across my project source files. Is there an fairly simple way to search and collect all those "foo"s that're preceded by @Name? In other words, I'd like to write a method that would return a Set<Foo> containing these. Thanks!!!

• how to remove error text from the email format checker code?

  - by rdesai

  I have been writing a code for validating forms using javascript/jquery. Following is a code snippet for checking email format. The problem is when I enter invalid email, it recognizes it, but when I go back to this field and enter correct email, the error text still stays even though I have used the 'else' part. How do I remove the error text in this case? if(e1.value!=''){ var emailRegEx = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i; if (document.signupForm.email1.value.search(emailRegEx) == -1) { $("#err_email1").html("Please enter valid email address."); } status=0; } else{ $("#err_email1").html(""); status=1; }

• iphone - Images (slide show) and audio snychronization

  - by Qaiser

  I have 20 images and some audio. I would like to show a single image at a time and change the images at (unequal) intervals. For example, I want to show image 1 for 1.44 seconds and image 2 for 1.67 seconds and so on. Can someone suggest how to go about doing this please? What I have seen are examples that show how to setup an array of images with one field that denotes total time. This causes the images to show for an equal amount of time (each). ... and that not what I am looking for ...

• Need to include #anchor after querystring list

  - by Bloopy

  Hello, Form is 'get' to a API which operates off of querystring. One of the parameters is a PackageID which indicates a vacation package. In order for the packageID to appear I also need to append '#packages' to the end of the get request. Since not all form 'get' have a package I need this to be dynamic. I've tried adding a hidden field with '#packages' as the value - however the '#' is automatically encoded and therefore not registered when the server grabs the URL. What would be the best way for me to dynamically include '#packages' as it appears in the querystring via javascript? Thanks!

• ActiveRecord date format

  - by Mongus Pong

  I've run into a spot of bother with date formats in our Rails application. I have a date field in our view which I want to be formatted as dd/mm/yy. This is how the user will expect to enter their dates, and the datepicker control uses this format. However, Active Record seems to be expecting mm/dd/yy. If I enter 01/03/2010, this gets put in as 03 January 2010. If I enter 25/03/2010, this gets put in a null. How do I get ActiveRecord to expect Her Majesties date format?

• Sql Server query performance

  - by Macros

  I have a stored procedure on a busy database which constantly come out top in the list of expensive queries (by some way). The query is very simple, it takes a single parameter (@ID, int) which is the primary key of the table, and selects the record that matches that ID. The primary key is an identity field with a clustered index, so I am stumped as to how to optimise this any further? The query is as follows CREATE PROCEDURE [dbo].[P_Call_Get] @ID int = null AS select ID, AppID, AgentID, AgentLogin, Ext, VDN, VDNName, Skill, SkillName, CallFrom, TelNoFrom, ParentCallID, CallStart, ACWStart, CallEnd, Outcome, StageID, TxTo, TxSuccess, ServiceID, DiallerID, CRC, TSCallID, CallDirection, [Manual], CallBackAgent, CallBackDateTime, Notes from P_Call where (ID = @ID or @ID is null) Not sure the best way to post the execution plan - all it shows is that 100% of the operation is taken up by the clustered index scan

• Order a List (C#) by many fields?

  - by Esabe

  Hi everyone, I want to order a List of objects in C# by many fields, not just by one. For example, let's suppose I have a class called X with two Attributes, A and B, and I have the following objects, in that order: object1 = A = "a", B = "h" object2 = A = "a", B = "c" object3 = A = "b", B = "x" object4 = A = "b", B = "b" and I want to order the list by A attribute first, and when they are equals, by B element, so the order would be: "a" "c" "a" "h" "b" "b" "b" "x" As far as I know, the OrderBy method order by one parameter. Question: How can I order a C# List by more than one field? Thank you very much

• Any ORMs that easily support access to raw table schema?

  - by fizil

  I work with a ASP.NET UI framework that pulls fields for a particular screen off a database. These fields can be associated with particular data fields in another database for binding. The idea with this setup is that if a client needs a new column on a table, they can easily add it, and create a UI field that binds to it without any sort of application restart or recompile. The problem I've always had with this is that it has meant I'm always having to work with untyped datasets in my code. Are there any ORM libraries for .NET out there that could easily accommodate the requirement of being able to access arbitrary columns in the table schema over and above ones mapped to strongly typed fields?

• Computed Column with relationships

  - by Sethery

  I have a table, MapLocation, which has a column and two relationships with tables that have a field that really need to be displayed as a single concatenated value. I was thinking this was a perfect case for a computed column, but not sure how to go about it. MapLocation MaoNo Section _____________________ _____________________ _____________________ MapNoId MapNoId SectionId SectionId MapNumber (int) Section (int) Identifier (nvarchar) LocationName (nvarchar) LocationName = "MapNUmber - SectionNumber - Identifier" ex: 20 - 03 - SW4 How would I write that? I haven't done much with computed columns or concatenating in SQL. Edit: I need an actual computed column that is automatically updated, im looking for the formula. Or is this more of a function/trigger? Its possible, I certainly barely know what I'm doing. The idea is that I dont want to have to do two more server calls and concatenate these values client side.

• Joomla 2.5 disable and remove Smart Cache

  - by WooDzu

  I am maintaining a Joomla 2.5 based magazine website with 3-4 new, long articles every day. Smart Search was enabled by default and now I've got a few "finder" tables full of indexed phrases and therms. I wonder if there are any disadvantages if I'd: Disable the Smart Search plugin Remove these 'finder' tables completely Aha, we're using a Search field, which works fine, but I'm not sure what's going to happen if I disable the plugin and remove these tables. Will it then search for phrases in content Joomla tables or simply break w/o missing 'finder' tables Has anyone tried this before?

• Splitting a double in two, C#

  - by Stacey

  I'm attempting to use a double to represent a bit of a dual-value type in a database that must sometimes accept two values, and sometimes accept only one (int). So the field is a float in the database, and in my C# code, it is a double (since mapping it via EF makes it a double for some reason... ) So basically what I want to do .. let's say 2.5 is the value. I want to separate that out into 2, and 5. Is there any implicit way to go about this?

• How is this problem usually solved without using sever-side scripting?

  - by cyggi

  Simple problem I have so far always solved via PHP: You have a site with header, menu, footer and content field. Header, menu and footer are usually the same for each page. How do you, without PHP or any other server-side language, have the header, menu and footer data exist only in one file? So that for example you don't have ten sites (like home.html, products.html, about.html, ..) all having a copy of the static header and menu in their html files. Now if you want to change the header you have to change ten files. I hope I made my question clear enough, if not please leave a comment :)

• How to perform dynamic formatting with perl during write?

  - by Bee

  I have a format which is defined like below: format STDOUT = ------------------------------------ |Field1 | Field2 | Field3 | ------------------------------------ |@<<<<<<<<<<| @<<<<<<<<<<<| @<<<<< |~~ shift(@list1),shift(@list2),shift(@list3) ------------------------------------ . write STDOUT; So the questions are as below: Is it possible to make the list of values printed dynamic? e.g. If list 1 contains 12 elements, and if $flag1 is defined, then print only elements 0..10 instead of all 12. I tried doing this by passing $flag as a parameter to the sub which generates the report. However, the last defined FORMAT seems to always take precedence and the final write when it happens, applies the last format no matter what the condition is. Is it possible to also add/hide fields using the same process. e.g. If $flag2 is defined, then add an additional field Field4 to the list?

• How can I improve this regular expression?

  - by Michael Haren

  I want a regular expression to match valid input into a Tags input field with the following properties: 1-5 tags Each tag is 1-30 characters long Valid tag characters are [a-zA-Z0-9-] input and tags can be separated by any amount of whitespace Here's what I have so far--it seems to work but I'm interested how it could be simplified or if it has any major flaws: \s*[a-zA-Z0-9-]{1,30}(\s+[a-zA-Z0-9-]{1,30}){0,4}\s* // that is: \s* // match all beginning whitespace [a-zA-Z0-9-]{1,30} // match the first tag (\s+[a-zA-Z0-9-]{1,30}){0,4} // match all subsequent tags \s* // match all ending whitespace Preprocessing the input to make the whitespace issue easier isn't an option (e.g. trimming or adding a space). If it matters, this will be used in javascript. Any suggestions would be appreciated, thanks!

• Setting an empty default value for a char-column in MySQL?

  - by user281434

  Hi In phpMyAdmin I have a char(32) column that has no default value(ie. Default: None). When I try to insert data through a SQL query, it throws out an error saying that the column "doesn't have a default value". I need it to be empty, so instead I've just set it's default value as "As defined: " and then nothing in the value field. Is this a bad idea? And is it any better than simply throwing in an empty value for the column in the SQL query? Thanks for your time.

• Turning user ID into name (seperate tables) in PHP

  I am currently trying to display the username of people who i am following, the problem is that during the following process, only the ID of me and the person i'm following is stored. I've got it to the point where the ID's are displayed but i'd like to show the names hyperlinked. $p_id is the profile ID. Here's what I've got: $following = mysql_query("SELECT `follower`, `followed` FROM user_follow WHERE follower=$p_id"); I am following: <?php while($apple = mysql_fetch_array($following)){ echo '<a href="'.$apple['followed'].'">+'.$apple['followed'].'</a> '; }?> The usernames are in a different table "users" under the field "username" - I need them to match up with the ID's that are currently displayed, and be displayed. Any help appreciated, thanks guys

• Rails 2.3.5: How to handle this type of validation

  - by randombits

  The use case is simple. I allow users to enter in an expiration field which needs to be between 1 and 15 into a form. The model takes that number and converts it into a datetime (such as adding 15 days from today) and stores it in the database. What's the correct way to actually validate that though? Do I validate against the datetime format that gets persisted in the database or the select box (1..15) that the user gets to pick through the form? I want to be able to validate that the user is putting in 1..15.. How is this done with ActiveRecord validation in Rails 2.3.5?
