ruby on rails - Save a local attachment on the server -


though paperclip gem used easy file uploads, have similar requirement @ server side. have generated image @ server , want save in various styles configured in paperclip options.

i have generated migration , model looks this:

attr_accessible :genimg has_attached_file :genimg   styles: { mini: '48x48>', small: '100x100>',             product: '240x240>', large: '600x600>' },   default_style: :product   url: '/images/:basename.:extension',   path: ':rails_root/app/assets/images/:basename.:extension'   convert_options: { all: '-strip -auto-orient' }

is there way can save local image in various formats using paperclip. how can so? if that's not possible, other possible way try out?

class yourcontroller < actioncontroller::base   def your_action     @image = image.find 1 # (might other way how asset)      file_path = '/path/to/your/file'     file      = file.open(file_path, 'r')      @image.asset = file     @image.save   end end

in console might do:

image.new(:data => file.new(path_to_your_file, "r"))

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
