• How could I generate instances of an object randomly at the top of the screen and make them "fall"?

  - by Custard

  I am making a game in Flash CS4 (actionscript 3) and I would like to be able to make "copies" of an instance that would randomly appear at the top of the screen and fall. For example, multiple objects(that are the same one) are falling from the top of the screen continuously, starting at random X positions. (i think this would be considered Real-Time effect). P.S., please tell me if the information is insufficient for an answer, I couldn't think of much more to add to it. Thanks for your time and answers, -Custard

  Hi, I'm looking for free tools to design the UI for my web app. I'm pretty new to this field, so please point me to acceptable solutions.

• Delphi component you can't live without?

  - by Warren P

  Most delphi developers have a list of delphi components they wouldn't live without. Not including anything that ships with Delphi (standard VCL or included third-party software like Rave or Indy), what are the components you can't live without, be they commercial or open-source? I will refrain from adding my own answers unless this becomes a community wiki. One component name, or product name, per answer please. Please vote up on components and do not post duplicates.

• VB6 code for Reading/Writing Windows Registry values

  - by Clay Nichols

  I'm looking for a good example of reading and writing to the Windows Registry using VB6. Yes, I know there are lots of mediocre examples. I spent an hour googling and testing. Some were incredibly complex, others had only some of the functions, and almost none of it had been vetted in any way (voted on). Since Stack Overflow is intended to the canonical location for answers to programming questions, it seems reasonable to post it here.

• Change encoding to UTF-8 recursively on Windows?

  - by Pekka

  Does anybody know a tool, preferably for the Explorer context menu, to recursively change the encoding of files in a project from / to UTF-8 and other encodings? Freeware or not too expensive would be great. Edit: Thanks for the answers, +1 for all of them as they are all fine but I am a lazy bastard sometimes, and would really like to be able to just right click a folder and say "convert all .php files to UTF-8". :) Further suggestions are appreciated.

• Ask Field formatting

  - by developer

  I am using ASK fields in a word document, wherein the user are prompted with questions and the document is then built with the answers that the user type in.

Also I want to change the font color of the question asked in the prompt box. Is it possible?

• Errors in c++ faq lite?

  - by Gianluca

  Hello, I'm reading questions and answers around here for a few days. I have seen the c++ faq lite at Parashift has been mentioned many times. Personally I have always considered it to be a good reference, not my favourite one but certainly useful. Here I have seen somebody advising it, but many others commenting against it instead. Somebody mentioned it's full of mistakes. Could you please point out which are the major errors in there, if any?

• How to detect slow internet connections?

  - by Starx

  Currently, most of the popular websites, like google, yahoo detect if the user connection speed is slow and then give a option to load basic version of the website instead of the high end one. What are the methods available to detect slow internet connections? P.S. I think this is achieved through javascript, so I will tag it as a javascript question? However, I am looking for answers oriented more towards PHP, if this is also server related.

• Is incremental Macro definition possible?

  - by Davorak

  I often find the following type of incremental definition useful: (define (foo) (display "bar")) (foo) ;prints bar (define foo (let ((bar foo)) (lambda () (display "foo") (bar)))) (foo) ;prints foobar How do I preform this type of incremental definition with macros? I could not get let-syntax to provide the same functionality. Currently I use plt scheme, but would like to see answers in different lisp implementations as well.

• Using PreferenceScreen/PreferenceActivity to configure home screen widgets

  - by hpe

  Hi, I'm creating an appwidget, where the user should be able to configure it before it is added to the home screen. To me, PreferenceScreen/PreferenceActivity seems perfect for the task, but the intention behind these classes seem to be configuring an actual application. I've searched, but cannot find any documentation or tutorials which covers this question. Is it possible to configure a widget using these classes, or is the only alternative to configure it through an ordinary view? Thanks for any answers!
