a daft question, cannot work: have long-running process in swing application may take several minutes. want display progress dialog user while process ongoing. want prevent user performing further actions, eg pressing button while process going on. if process on edt, prevents end-user doing while process going on. because edt busy processing, never gets around rendering dialog's content, outline of dialog. but if process in worker thread, end-user can click buttons , cause edt manipulate state worker manipulating @ same time, bad stuff consequence. if make dialog modal, not happen, modal in swing implies blocking , moment call setvisible(true) , thread blocks forever. so current "solution" use worker thread, , spawn off separate thread purpose absorb blocking nature of setvisible . surely there must better solution! so how dialog prevents user interacting rest of system (modal) not block thread causes visible? you should using glasspane preventing u...

i've downloaded ready lisp , playing around repl. want know is, how write long program, interpret , output? sort of plt scheme has. i'd minimal amount of hassle if that's possible. want on book i'm reading. thanks. common lisp provides functions load , compile-file . load load lisp textual source code or compiled files , execute those. printing done go usual output streams. compile-file allows generate compiled file file lisp source code. has advantage programs typically running faster when using file compiler , compiler checking , might give optimization hints. many implementations generate native machine code. file generated compile-file can loaded load. note in common lisp 1 uses running lisp compile , load code. in plt scheme model used each 'start' code gets executed in fresh scheme. may beginners, waste of time writing larger software.

the real use of --whole-archive linker option have seen in creating shared libraries static ones. came across makefile(s) use option when linking in house static libraries. of course causes executables unnecessarily pull in unreferenced object code. reaction this plain wrong, missing here ? the second question have has read regarding whole-archive option couldn't quite parse. effect --whole-archive option should used while linking static library if executable links shared library in turn has (in part) same object code static library. shared library , static library have overlap in terms of object code. using option force symbols(regardless of use) resolved in executable. supposed avoid object code duplication. confusing, if symbol refereed in program must resolved uniquely @ link time, business duplication ? (forgive me if paragraph not quite epitome of clarity) thanks there legitimate uses of --whole-archive when linking executable static libraries. 1 example ...

i using plugin scheduled job.but not working. confused points,should need create job class , set name in schedule file?when testing then,should run rescue scheduler , resque worker both or 1 of them. thanks in advance. my resque scheduler config... need these pieces: yml file (config/resque_scheduler.yml): every_1_minute: cron: "* * * * *" class: everyminute queue: some_queue description: tasks perform every minute config/initializers/resque.rb: require 'resque_scheduler' resque.schedule = yaml.load_file(file.join(rails.root, 'config/resque_scheduler.yml')) ruby class (lib/every_minute.rb or somewhere in load path): class everyminute def self.perform puts "hello every minute!" end end you need run rake resque:scheduler rake resque:work the resque:scheduler process periodically queues jobs, hence scheduling. , workers jobs blindly. why need both schedule , run jobs periodically.

i've got project 2 files want source-control using mercurial: a scx-file binary (database) file a sct-file text file my filter: [encode] **.scx = tempfile: sccxml infile outfile 0 [decode] **.scx = tempfile: sccxml infile outfile 1 problem sccxml receives path scx-file the scx-file can not converted text-file without corresponding sct-file workarounds is possible combine files before filter runs? is possible pass both file's paths sccxml-converter? update: no, i'm using not using win32text extension. sccxml-executable needs both sct-file , scx-file parameter convert them text-file (the text-representations of both files tar'ed 1 file). i want have binary files text-file in repo, meaningful diffs. trying achieve using precommit hook.

i want create sports application contains following. tabhost 3 main categories. (news, tables, live score) the news category have 2 sub categories.
