• What is the best way to write class template-like generic code in C?

  I need to write AVL-tree with generic type in C. The best way I know is to use [ void* ] and to write some functions for creating, copying, assignment and destruction. Please, tell me some better way.

• how to reuse a CASE in the WHERE ?

  - by Thibault Witzig

  Hello I'm trying to do a request that looks like this SELECT field1, field2, field3 = CASE WHEN field2 = 'something' THEN 'something' WHEN field1 IS NOT NULL and field2 IS NULL THEN 'somethingElse' ELSE NULL END FROM SomeTable WHERE field3 IS NOT NULL This results in a syntax error. I have to rewrite the CASE in the WHERE instead of just refering to it. Is there a better way to achieve this ? And out of curiosity, why is "WHERE field3 IS NOT NULL" refused while for example "ORDER BY field3" would pass ?

• Replacing multiple `-` with one `-` without regexp

  - by Adam Kiss

  I've seen so many misuses of RegExp, I don't really like it :) I have string (as a result of two str_replaces) that might look something like this: .?This iš my ".stRiNg."! | V --this-is-my---string--- Is there any way better than $string = trim(preg_replace('/[-]+/u','-', $string),'-'); to get: this-is-my-string ?

• Multiple branch merges, stick with Subversion or move to Mercurial or Git?

  - by casualcoder

  Given a situation where there are three branches, A, B and C, where A is merged to both B and C on a regular basis. From time to time B is merged to C. With Subversion, B apparently must be removed and recreated after every merge to C. This raises groans from colleagues, but would any alternative do any better? It would seem to me that Mercurial would not. Perhaps Git? Does anyone else run into this problem?

• NullDisplayText in markup vs ISNULL(field, 0) in SQL?

  - by abatishchev

  Which approach is better to use: BoundField.NullDisplayText isn't set. NULL-case is foreseen in SQL query, i.e. SELECT ISNULL(amount, 0) FROM table or BoundField.NullDisplayText is set, e.g. "0.00 %". NULL-case isn't foreseen in SQL query, i.e. SELECT amount FROM table What do you think?

• J2EE v6 and .NET 4.0 comparison

  - by sme89288

  We are running our applications on .NET 3.5 and are planning on either updating to .NET 4.0 or switching entirely to the Java platform, J2EE v6, as we've heard from some clients that "it's better." Can anyone either explain some of the large differences between the two platforms and maybe what kind of costs would be associated with switching to Java rather than just updating, or point me to some articles or papers that make such comparisons? Thanks!

• Should I use AJAX or get every data beforehand

  - by rix501

  I have a web app where I need to change a drop down list dynamically depending on another drop down list. I have two options: Get all the data beforehand with PHP and "manage" it later with Javascript. Or get the data the user wants through AJAX. The thing is, that the page loads with all the data by default and the user can later select a sub category to narrow the drop downs. Which of the two options are better (faster, less resource intensive)?

• Does it make sense to test ui components seperately?

  - by Bless Yahu

  I'm working on a webform that has about 15 user controls, separated by context (comments, locations, members/leaders, etc).   If each control can render individually (using real or test data), does it make sense to have a seperate "functional" test page to test them in isolation or is there a better way?

• Database Design Question

  - by Soo

  Ok SO, I have a user table and want to define groups of users together. The best solution I have for this is to create three database tables as follows: UserTable user_id user_name UserGroupLink group_id member_id GroupInfo group_id group_name This method keeps the member and group information separate. This is just my way of thinking. Is there a better way to do this? Also, what is a good naming convention for tables that link two other tables?
