• SQL Server - Filter field contents to numbers only

  - by Alex

  How can I copy the value of a field, but only its numbers? I am creating a computed column for fulltext search, and I want to copy the values from my Phone Number fields (which are varchar) into it, but not with their formatting - numbers only. What is the command that would do this in my computed column formula? Thank you!

• How to set JComboBox not to select an element when created? (Java)

  - by Alex Cheng

  Hi all. Problem: I am using JComboBox, and tried using setSelectionIndex(-1) in my code (this code is placed in caretInvoke()) suggestionComboBox.removeAllItems(); for (int i = 0; i < suggestions.length; i++) { suggestionComboBox.addItem(suggestions[i]); } suggestionComboBox.setSelectedIndex(-1); suggestionComboBox.setEnabled(true); This is the initial setting when it was added to a pane: suggestionComboBox = new JComboBox(); suggestionComboBox.setEditable(false); suggestionComboBox.setPreferredSize(new Dimension(25, 25)); suggestionComboBox.addActionListener(new SuggestionComboBoxListener()); When the caretInvoke triggers the ComboBox initialisation, even before the user selects an element, the actionPerformed is already triggered (I tried a JOptionPane here): First popup (notice that "flow byte_jump" is selected): Second popup (I think the setSelectionIndex is executed) Then in the end: The problem is: My program autoinserts the selected text when the user selects an element from the ComboBox. So without the user selecting anything, it is automatically inserted already. How can I overcome the problem in this situation? Thanks.

• How do I delete in Django? (mysql transactions)

  - by alex

  If you are familiar with Django, you know that they have a Authentication system with User model. Of course, I have many other tables that have a Foreign Key to this User model. If I want to delete this user, how do I architect a script (or through mysql itself) to delete every table that is related to this user? My only worry is that I can do this manually...but if I add a table , but I forget to add that table to my DELETE operation...then I have a row that links to a deleted, non-existing User.

• Javascript code plagiarism checker

  - by Alex Ciminian

  I was wondering if there was any tool available that detects code plagiarism and works well with Javascript. I want to test assignment submissions for homework I'm going to hand out. The only tool that I know of that can do this is MOSS, but, from what I've heard, it's pretty poor for anything else than C. Unfortunately, I can't test it yet because I don't have submissions :).

• Align child element to bottom with CSS

  - by alex

  I have a form input, and the label spans multiple lines, and I want the corresponding checkbox to appear at the bottom (last line of the label element). Here is what I was playing with CSS .standard-form { width: 500px; border: 1px solid red; } .standard-form .input-row { overflow: hidden; margin-bottom: 0.8em; } .standard-form label { width: 25%; float: left; } .standard-form .input-container { width: 70%; float: right; } .standard-form .checkbox .input-container { display: table-cell; height: 100%; vertical-align: text-bottom; } HTML <form class="standard-form"> <div class="input-row checkbox" id="permission"> <label for="input-permission"> Do I hereby grant you permission to do whatever tasks are neccessary to achieve an ideal outcome? </label> <div class="input-container"> <input type="checkbox" id="input-permission" name="permission" value="true" /> </div> </div> </form> It is also online at JSbin. Is there any way to do this? I notice that div.input-container isn't expanding, which is the old multi column problem with CSS. I thought I could get this going with display: table-cell and vertical-align: bottom but I haven't been able to do it yet. I don't mind that IE6/7 won't render it correctly.

• How can I write this Table Valued Function as a Stored Procedure?

  - by Alex

  I have the following TVF for fulltext search: FUNCTION [dbo].[Fishes_FullTextSearch] (@searchtext nvarchar(4000), @limitcount int) RETURNS TABLE AS RETURN SELECT * FROM Fishes INNER JOIN CONTAINSTABLE(Fishes, *, @searchtext, @limitcount) AS KEY_TBL ON Fishes.Id = KEY_TBL.[KEY] When I'm using this TVF, it doesn't return a collection of objects of type Fish (which I want!) - instead LINQ creates a new result type which includes all "Fish" fields and the fields Key and Rank. In another question, it was suggested that I rewrite this TVF into a stored procedure for it to return Fish objects only. Can someone help me do this please? Also, it needs to be ordered by Rank. Thank you!

• Validating primitive types in ASP.NET MVC

  - by Alex

  I've implemented the following classes to validate data public abstract class Validated { public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } public abstract IEnumerable<RuleViolation> GetRuleViolations(); } public partial class User: Validated { public override IEnumerable<RuleViolation> GetRuleViolations() { if (this.Age < 1) yield return new RuleViolation("Age can't be less than 1"); } } It works great! When the form is submitted I just do if (user.IsValid == false) blah... But I still need to validate that the Age is an integer int a = 0; if (!int.TryParse(age, out a)) { error = "Not integer"; // ... } How can I move this to my model?

• Can PHP's glob() be made to find files in a case insensitive manner?

  - by alex

  I want all CSV files in a directory, so I use glob('my/dir/*.CSV') This however doesn't find files with a lowercase CSV extension. I could use glob('my/dir/*.{CSV,csv}', GLOB_BRACE); But is there a way to allow all mixed case versions? Or is this just a limitation of glob() ?

• Java technologies for web-development.

  - by Alex

  Hello. I'm PHP-programmer, but I'm extremely interested in learning Java. So I decided to change speciality from PHP to Java. At the moment I have an opportunity to try to make quite simple web-application (it should contain 2-3 forms, several pages with information from the database and authorization module) and also I have a chance to choose any technology I want. Besides I have about 3 months for this task. I've decided to develop site with Java technologies for the purpose of studying. I've already read a book about Java ("Java2 Complete Reference" by P.Naughton) and currently I'm reading "Thinking in Java" by B.Eckel. I clearly understand it's not enough for efficient development, but I want, at least, to try. I would be very appreciated for the advises, which framework (for example) or technology to choose (Spring, Grails etc.) and what primary aspects and technologies of Java should I pay attention to? Thank you in advance.

• Need to escape a special character in a jQuery selector string

  - by alex

  According to the selectors docs, you must escape [ with double backslash, etc \\[. I have a selector that is created like so (assume val attribute is something[4][2] in this example). var val = $(this).attr('val'); $select.find('option[value=' + val + ']').show(); Can I write a regex to escape the brackets for me?

• How can I disable the F4 key from showing the items in a ComboBox

  - by Alex

  You might not know this, but pressing the F4 key on a ComboBox makes it's drop-down item list appear. I believe this is the default behavior on Windows. Does anyone know how to override this behavior in WPF (C#)? I know that overriding default behavior is generally seen as bad practice, however in this case I have a rugged-device that runs XP Embedded. It has a handful of prominent Function keys (F1-F6) that need to trigger different events. This works fine, however when focused over a ComboBox the events aren't triggered as the ComboBox drops down. I have tried catching the KeyDown event both on the form and on the ComboBox and listening for the F4 key, however it doesn't get this far as the key press must be handled at a lower level. Any ideas? Thanks.

• What's the new way to iterate over a Java Map in Scala 2.8.0?

  - by Alex R

  How does scala.collection.JavaConversions supercede the answers given here: http://stackoverflow.com/questions/495741/iterating-over-java-collections-in-scala (doesn't work because the "jcl" package is gone) and here http://www.eishay.com/2009/05/iterating-over-map-with-scala.html (doesn't work me in a complicated test which I'll try to boil down and post here later) The latter is actually a Scala Map question but I think I need to know both answers in order to iterate over a java.util.Map. Thanks

• MySQL select one field from table WHERE condition is in multiple rows

  - by Alex

  Tried to find the answer, but still couldn't.. The table is as follows: id, keyword, value 1 display 15.6 1 harddrive 320 1 ram 3 So what i need is something like this.. Select an id from this table where (keyword="display" and value="15.6") AND (keyword="harddrive" and value="320") There's also a possibility that there will be 3 or 4 such keyword conditions which should result into returning one id (one row) It seems there's something to deal with UNION but i didn't use it before so i can't figure it out Thanks in advance

• Is there any tips for minimising access to a public page without login?

  - by alex

  I have a page that is just a non interactive display for a shop window. Obviously, I don't link to it, and I'd also like to avoid people stumbling across it (by Google etc). It will always be powered by Chrome. I have thought of... Checking User Agent for Chrome Ensuring resolution is 1920 x 1080 (not that useful as it is a client side check) Banning under robots.txt to keep Google out of it Do you have any more suggestions? Should I not really worry about it?

• How to exit a process run with Ruby if it takes more than 5 seconds?

  - by Alex

  I'm implementing a checking system in Ruby. It runs executables with different tests. If the solution is not correct, it can take forever for it to finish with certain hard tests. That's why I want to limit the execution time to 5 seconds. I'm using system() function to run executables: system("./solution"); .NET has a great WaitForExit() method, what about Ruby?. Is there a way to limit external process' execution time to 5 seconds? Thanks

• Query Execution Plan - When is the Where clause executed?

  - by Alex

  I have a query like this (created by LINQ): SELECT [t0].[Id], [t0].[CreationDate], [t0].[CreatorId] FROM [dbo].[DataFTS]('test', 100) AS [t0] WHERE [t0].[CreatorId] = 1 ORDER BY [t0].[RANK] DataFTS is a full-text search table valued function. The query execution plan looks like this: SELECT (0%) - Sort (23%) - Nested Loops (Inner Join) (1%) - Sort (Top N Sort) (25%) - Stream Aggregate (0%) - Stream Aggregate (0%) - Compute Scalar (0%) - Table Valued Function (FullTextMatch) (13%) | | - Clustered Index Seek (38%) Does this mean that the WHERE clause ([CreatorId] = 1) is executed prior to the TVF ( full text search) or after the full text search? Thank you.
