Heya all, I don''t think I''ve been paying attention. When a Windows API function fails, I could have been doing this: raise SystemCallError(GetLastError()) Instead of this: # Where ''Error'' is nested under the current class. raise Error, get_last_error I''m not sure how big of a deal this is in practice, however, or if it''s even preferred for our purposes.

Similar to python and perl. But MUCH easier (especially considering that this is the first time I've every tried to run Ruby). I even had fun making set_error() polymorphic.

Hi, I have one minor issue. I''m trying to check whether a directory is empty given some path to the directory. My code does the following: if(File.directory?(dirpath)) # dirpath = public/images/1 if(File.zero?(dirpath)) FileUtils.rm_rf(dirpath) end end The problem is, while testing this, if I put a file in the directory and run the above code, it still ends up deleting the

Hi, I have a problem where I need an auto-incremented id back from the database for a statement that has yet to be committed. The operation that uses the id may fail, and if so, I need to rollback the database. I can''t figure out how to send only the statement to the database without the commit without sending over hard coded SQL. This is what I started out with: 1 def add_album

...JAX (all of this is working so far). How would I correctly wrap the worker in a begin..rescue so that it spits out ''invalid command'' when someone types in something incorrect. Right now, I have: def start_working begin @result = IO.popen(@cmd) rescue SystemCallError @result = "Invalid or Failed Command: " + $! end end but in my view, the @result doesn''t seem to be accessible to the ajax periodical updater in the same way the @result from the popen is... what am i missing?

Hi, I have a quick question. I am trying to create folders dinamically using FileUtils.mkdir, the problem is that if the folder already exist it gives me an error. Does anyone know if there are any options to mkdir that would let me overwrite the already existing directory? I just need to create a folder with the same name everytime. Any other solution you might suggest? Thanks. -- Posted
