• To change checkbox text or to not change?

  - by Axarydax

  Hi, I'm having an argument with a co-worker, and I'm trying to convince him that it's a bad idea to change checkbox text (label) according to the checkbox state. For example, we have a combobox that automatically picks selected value (and is disabled) when checkbox next to it is checked and is enabled when checkbox is cleared. His idea is to show Autoselect when checkbox is checked and Manual select when it's cleared. I'm sure that this will confuse the user as users tend to think that checking a checkbox next to a verb will make it true, only to find that the label has changed to something else. What is your opinion on this matter? P.S. I remember reading about changing checkbox text somewhere, in a book or blog article, but can't remember where. It would be great to have this in writing :-)

• Exploding a range of dates with LINQ

  - by Robert Gowland

  If I have a pair of dates, and I want to generate a list of all the dates between them (inclusive), I can do something like: System.DateTime s = new System.DateTime(2010, 06, 05); System.DateTime e = new System.DateTime(2010, 06, 09); var list = Enumerable.Range(0, (e - s).Days) .Select(value => s.AddDays(value)); What I'm stuck on is that I've got a list of pairs of dates that I want to explode into a list of all the dates between them. Example: {2010-05-06, 2010-05-09}, {2010-05-12, 2010-05-15} should result in {2010-05-06, 2010-05-07, 2010-05-08, 2010-05-09, 2010-05-12, 2010-05-13, 2010-05-14, 2010-05-15} Note the pairs of dates are guaranteed not to overlap each other.

• How to create custom CSS "on the fly" based on account settings in a Django site?

  - by sdolan

  So I'm writing a Django based website that allows users select a color scheme through an administration interface. I already have middleware/context processors that links the current request (based on domain) to the account. My question is how to dynamically serve the CSS with the account's custom color scheme. I see two options: Add a CSS block to the base template that overrides the styles w/variables passed in through a context processors. Use a custom URL (e.g. "/static/dynamic/css//styles.css") that gets routed to a view that grabs all the necessary values and creates the css file. I'm content with either option, but was wondering if anyone else out there has dealt with similar problems and could give some insight as to "Best Practices".

• Problem installing wordpress child themes.

  - by Jay

  Hi, I've tried to install either the Fusion or Thematic child themes for my blog. My Wordpress directory is located at myblog/wordpress while my domain is just myblog (example). Everything works fine with both basic themes or the parent Fusion or Thematic themes. When I install a child theme for either framework, I can view the preview and select 'activate.' However, after that my entire site crashes. I can't even view the wordpress admin panel. I've had to restore my database from my hosting provider just to get my blog working. All that I'm able to see is my favicon icon and a blank page. I've tried to deactivate all plugins and this doesn't help either. I really want to use the Hybrid News child template. Any thoughts on what might be happening? thanks so much!

• What are the typical reasons Javascript developed on IE fails on Firefox?

  - by lwburk

  Inspired by this post it occurs to me that I often suffer from the opposite problem. That is, I've got code in a legacy application designed only for Internet Explorer and I need to get it to work in Firefox. For example, I recently worked on an app that made heavy use of manually simulating click events, like this: select.options[0].click(); ...which completely broke the application in Firefox. But you wouldn't find that information in the answers to the other question, because that's not something you'd ever even attempt if your app first targeted Firefox. What other things should a developer updating a legacy IE-only application look for when migrating to modern browsers?

• How to prevent an automerge using git?

  - by marckassay

  I am trying to merge a local branch into the master branch without having Git to do an automerge. I would like to “hand pick” what I would like to be merged into master. When I use Git’s difftool command, I am able to diff and select what I want to be added into the master branch. But then when I do a merge, I will lose what I selected prior because Git will do an automerge. I can commit the changes into master prior to the merge, but doing so seems unnatural. And Git’s mergetool is only available when there are conflicts from a merge. But if Git does an automerge then usually there aren’t conflicts, so I am unable to run the mergetool command.

• How to determine the date that Office 2003 was installed

  - by GalleySlave

  Is there any guaranteed way of determining the date that Office 2003 (and .Net Framework v2.0) were installed on a client computer? I am trying to nail down a problem which I think is due to the order that the .Net Framework and Office 2003 were installed in, so I need a way I can get a client to have a look at their machine (preferably the file system) and let me know. It may require admin privileges (or Registry etc) which wouldn't be a problem but not the preferred solution. It appears that the folders under Program Files\Microsoft Office\Office11 have a number with the same date which at first sight appear to be an installation date / time. Likewise in Windows\Microsoft.Net\Framework\v2.0.50727 there are two with the same date, but this seems less certain. I could use WMI with a winmgmts:object and SELECT * FROM Win32_Product, but was wondering if there was a 'telephone' way to do it!

• MySQL: Selecting One Record When Others Have Same Data

  - by LoganFrederick

  I have a table of cities that all share the same area code: 367 01451 Harvard Worcester Massachusetts MA 978 Eastern 368 01452 Hubbardston Worcester Massachusetts MA 978 Eastern 369 01453 Leominster Worcester Massachusetts MA 978 Eastern The table has multiple area codes, all with multiple cities. What I'd like to do is only select one city from each area code and delete any extra cities from duplicate area codes. What would be the best query to accomplish this? I believe: http://stackoverflow.com/questions/596629/mysql4-sql-for-selecting-one-or-zero-record Is coming close to what I need but didn't quite get what/how those answers were working. Note The "978" row is the "area_code" row, table name is "zip_code".

• Design best practice - best way to handle user selection

  - by user1457227

  I'm an experienced developer (WPF) moving over to Android development. My question: an app I am developing allows the user to browse their local storage (such as SDCARD) and select a file. Now, should I simply create a new Activity (after the user has made a selection) to handle what I want to have the app do with that chosen file, -or- is the better approach to pass the path/name of the selected file back to the main Activity and let IT launch the next Activity? In other words, is the better practice to have the main Activity launch other (support) activities, or is it perfectly ok and normal to have one activity chain to another and on and on? Thanks!

• How do I get every nth row in a table, or how do I break up a subset of a table into sets or rows of

  - by Jherico

  I have a table of heterogeneous pieces of data identified by a primary key (ID) and a type identifier (TYPE_ID). I would like to be able to perform a query that returns me a set of ranges for a given type broken into even page sizes. For instance, if there are 10,000 records of type '1' and I specify a page size of 1000, I want 10 pairs of numbers back representing values I can use in a BETWEEN clause in subsequent queries to query the DB 1000 records at a time. My initial attempt was something like this select id, rownum from CONTENT_TABLE where type_id = ? and mod(rownum, ?) = 0 But this doesn't work.

• Anyway to get a value similar to @@ROWCOUNT when TOP is used?

  - by cfeduke

  If I have a SQL statement such as: SELECT TOP 5 * FROM Person WHERE Name LIKE 'Sm%' ORDER BY ID DESC PRINT @@ROWCOUNT -- shows '5' Is there anyway to get a value like @@ROWCOUNT that is the actual count of all of the rows that match the query without re-issuing the query again sans the TOP 5? The actual problem is a much more complex and intensive query that performs beautifully since we can use TOP n or SET ROWCOUNT n but then we cannot get a total count which is required to display paging information in the UI correctly. Presently we have to re-issue the query with a @Count = COUNT(ID) instead of *.

• VB.NET Loacalization

  - by PandaNL

  In my winform app in VB.NET i want to use the localization option. But i have a few questions/problems. I'm using a menu strip to select an other language. But it seems that is doesn't change my menustip text to my selected language. It does change my labels, buttons, and textboxes but menu strips doesnt seem to change when i choose an other language. Also is it possible to get those resx files such as MyForm.fr-FR.resx compiled so it isn't an external file outside my app? Or to get those files in an Language folder at the same location of my app, so i don't have all those fr-FR, nl-Nl folders in the same location as my program.

• Passing a column name instead of index in sqlite3

  - by user271753

  The problem code: NSString *query = @"SELECT Name FROM Category"; sqlite3_stmt *statement; if (sqlite3_prepare_v2(database, [query UTF8String], -1, &statement, nil) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { char *row =(char *)sqlite3_column_text(statement,0); char *rowData = (char *)sqlite3_column_text(statement,1); NSString *fieldName = [[NSString alloc] initWithUTF8String:row]; NSString *fieldValue = [[NSString alloc] initWithUTF8String:rowData]; NSLog(@"%@",fieldName); NSLog(@"%@",fieldValue); [fieldName release]; [fieldValue release]; } sqlite3_finalize(statement); } char *row =(char *)sqlite3_column_text(statement,0); In the above code instead of 0 can't I just pass a column name? How can I do that ?

• Show data relationship in gridview with dropdownlist or similar?

  - by Anders Svensson

  I have data coming from two tables with a foreign key relationship - one User table containing users of the web application, and one Page table containing details about pages visited by each user. I would like to be able to view these data in a gridview or the like on a page. It's easy enough to just show the User table data like so (I'm using the Entity Framework and LINQ): UserDBEntities context = new UserDBEntities(); GridView1.DataSource = from user in context.UserSet select new { user.Ip, user.Count, user.Description, user.Referer }; GridView1.DataBind(); But how can I show the Page details? I'm not bent on any particular way of showing it, but the only idea I've been able to come up with is to have a dropdown list for each user in a column. But I can't figure out how to get the page data into such a dropdown list. The tables are associated with the primary/foreign key UserID. Any ideas would be welcome (dropdownlist solution or other)!

• Even lighter than SQLite

  - by Richard Fabian

  I've been looking for a C++ SQL library implementation that is simple to hook in like SQLite, but faster and smaller. My projects are in games development and there's definitely a cutoff point between needing to pass the ACID test and wanting some extreme performance. I'm willing to move away from SQL string style queries, allowing it to be code driven, but I haven't found anything out there that provides SQL like flexibility while also preferring performance over the ACID test. I don't want to go reinventing the wheel, and the idea of implementing an SQL library on my own is quite daunting, even if it's only going to be simple subset of all the calls you could make. I need the basic commands (SELECT, MODIFY, DELETE, INSERT, with JOIN, and WHERE), not data operations (like sorting, min, max, count) and don't need the database to be atomic, or even enforce consistency (I can use a real SQL service while I'm testing and debugging).

• laravel multiple where clauses within a loop

  - by user1424508

  Pretty much I want the query to select all records of users that are 25 years old AND are either between 150-170cm OR 190-200cm. I have this query written down below. However the problem is it keeps getting 25 year olds OR people who are 190-200cm instead of 25 year olds that are 150-170 OR 25 year olds that 190-200cm tall. How can I fix this? thanks $heightarray=array(array(150,170),array(190,200)); $user->where('age',25); for($i=0;$i<count($heightarray);i++){ if($i==0){ $user->whereBetween('height',$heightarray[$i]) }else{ $user->orWhereBetween('height',$heightarray[$i]) } } $user->get(); Edit: I tried advanced wheres (http://laravel.com/docs/queries#advanced-wheres) and it doesn't work for me as I cannot pass the $heightarray parameter into the closure. from laravel documentation DB::table('users') ->where('name', '=', 'John') ->orWhere(function($query) { $query->where('votes', '>', 100) ->where('title', '<>', 'Admin'); }) ->get();

• WF - Creating a selective list

  - by Michael Bendtsen

  I have a stupid question. I have created a workflow Designer host where I publish my own activities. I also have a property grid which only displays the properties decorated with a special attribute. This designer is going to be used by none IT staff. What I want is that on an activity the user can select a property value from a list. I know I just could create an Enum but I would like it to be dynamic. I.e. all events on a specific interface (extracted using reflection). Is this at all possible or am I stuck with enums?

Please suggest accordingly. Thanks in advance

• How can I strip line breaks from my XML with XSLT?

Although it works, it's awfully messy. How can I prevent this?

• Fastest way for inserting very large number of records into a Table in SQL

  - by Irchi

  The problem is, we have a huge number of records (more than a million) to be inserted into a single table from a Java application. The records are created by the Java code, it's not a move from another table, so INSERT/SELECT won't help. Currently, my bottleneck is the INSERT statements. I'm using PreparedStatement to speed-up the process, but I can't get more than 50 recods per second on a normal server. The table is not complicated at all, and there are no indexes defined on it. The process takes too long, and the time it takes will make problems. What can I do to get the maximum speed (INSERT per second) possible? Database: MS SQL 2008. Application: Java-based, using Microsoft JDBC driver.
