• bind key to complete filename wherever the context is in Zsh

  - by lilydjwg

  Sometimes I want a filename instead of what zsh guesses for me. For example, I have a PNG file without a proper .png suffix, which makes zsh think it isn't a picture and won't list it when I type Tab to complete arguments of display.

• Open x86 'SOFTWARE' registry key on an x64 machine in C#

  - by Lance May

  I am trying to read the 32-bit HKLM\SOFTWARE registry key from a 64-bit (C#) application. This, of course, keeps redirecting my view to HKLM\SOFTWARE\Wow6432Node.

• Iterating over key/value pairs in a dict sorted by keys

• Trying to parse out the $_POST key names that I don't want

  - by Adam

  $post_keys = array_keys($_POST); $special_keys = array(); for($i=0;$i<count($post_keys);$i++){ if(strpos($post_keys[$i], "special") !== false){ $special_keys[] = $post_keys[$i]; } } I have numerous post vars with naming conventions such as special0, special0_time, special0_duration, special1, special1_time etc.... What I want to do is to find out how many main groups there are, so special0, special1 etc... The code I currently have searches all key names that have "special" in it, thus retrieving more than I want.
