• How can I get Eclipse to insert tabs instead of spaces for Java content assist?

  - by Simon Nickerson

  Is there any way to persuade Eclipse to use tabs instead of spaces for indenting its built-in Java content assist proposals (such as when creating an empty method which overrides a method in the parent class)? The only setting I could find that looked relevant is in Windows/Preferences/General/Editors/Text Editors/Insert spaces for tabs, and this setting is unchecked. At the moment I have to remember to select them and re-format with <Ctrl>+<Shift>+<F>.

• How to create ActiveX DLL in Visual C++

  - by Eric Lavitsky

  Is there a tutorial/reference for creating an ActiveX DLL in Visual Studio 2008 C++ ? I've got a DLL built with the DLLRegisterServer/UnregisterServer, and it's registered, but I'm having a little trouble figuring out what name to use to reference it (from a vbscript) and how to make sure my functions are exported correctly. Do I have to put my functions in a special class? Thanks!

• Can I use IP addresses to limit API access

  - by ed209

  I have a mini API that is only for an app I have built. The API service is on a separate domain to my app. I make jsonp calls to it and receive json in return. Therefore I only want my app to be able to access it. Can I just list a series of IP addresses for my app and allow them? Is there a better way to stop requests from anyone else to my API?

• Tools and tips for switching CMS

  - by Jimmy

  I work for a university, and in the past year we finally broke away from our static HTML site of several thousand pages and moved to a Drupal site. This obviously entails massive amounts of data entry. What if you're already using a CMS and are switching to another one that better suits your needs? How do you minimize the mountain of data entry during such a huge change? Are there tools built for this, or some best practices one should follow?

• Given an array of arrays, how can I replace all empty values with 0?

  - by stormist

  Example array $myArray[0] = array('23, null, 43, 12'); $myArray[1] = array('null, null, 53, 19'); $myArray[2] = array('12, 13, 14, null'); All nulls should be replaced with 0. I was hoping someone would have an efficient way of doing this, perhaps a built in PHP function that I am unaware of.

• A viewmodel's role beyond databinding?

  - by DeanMc

  I'm a bit confused as to what a viewmodel's role is beyond databinding. I have a menu built in silverlight. The menu has x number of menu items which is determined at runtime. One of the features I would like to add to this is that each menuitem has a different text colour when hovered over. Is it the role of the view to have a colour selector method or should the view handle this in it's code behind?

• Decimal type in Qt (C++)

  - by Dave

  What is the correct type to use in Qt development (or C++ in general) for decimal arithmetic, i.e. the equivalent of System.Decimal struct in .Net? Does Qt provide a built-in struct? (I can't find it in the docs, but maybe don't know where to look.) Is there a "standard" C++ library to use?

• Do null SQLite Data fields take up extra memory?

  - by CSharperWithJava

  I'm using the built in sqlite library on the Android platform. I'm considering adding several general purpose fields that users will be able to use for their own custom applications, but these fields will be blank most of the time. My question is, how much overhead will these blank fields add to my database? Do null fields even take up per record memory in sqlite? If so, how much? I don't quite understand the inner workings of a sqlite database.
