c# - Can I "block" a function until an asynch thread has finished? -


i have code on winform:

private void buttonstart_click(object sender, eventargs e) {     task.factory.startnew(() => threadfunction())         .continuewith(t => threadfunctioncomplete()         , cancellationtoken.none         , taskcontinuationoptions.none         , taskscheduler.fromcurrentsynchronizationcontext());      threadfinished(); }

and i'd start threadfinished() when threadfunctioncomplete() has been finished. well, put threadfinished() @ end of threadfunctioncomplete(), workflow of process won't. possible? sort of wait/lock maybe?

basically, can call continuewith twice:

task.factory.startnew(....)             .continuewith(...)             .continuewith(...)

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
