Hi everyone, I''m using WxRuby to develop a GUI app, and it needs to transfer files through ftp. If I use ftp.put_binary method, the GUI can response, but the ftp is very slow. And if I use Process.create and Process.waitpid to call windows ftp, it''s much faster, but the GUI doesn''t respond at all until the ftp is finished. Please tell me if there''s other way to do ftp in a GUI app, with a high ftp speed and responsable GUI. Thanks. -- Posted via http://www.ruby-forum.com/.

There are a lot of wxruby discussions on using threads - have a search through the archives for further info and examples, and also have a look in the samples directory included with wxruby. alex
Hi,
Thanks for you reply. My problem is:
For example, I created 4 threads, one of them is for wxruby GUI, and the
other three will do similar things as below. Then I found that, When
call_external in one thread is processing, the GUI thread(wonn''t
response) and the other two threads(wonn''t do step2) will wait(because
I
use Process.waitpid?)
But I hope only the caller thread wait for call_external to end, the
other threads just continue there own behavior.
#---------------------------------------
for i in 1..3 do
Thread.new{
call_external(xxx to use system ftp)
...do step2
}
end
#---------------------------------------
def call_external(cmd)
pid = Process.create( :app_name => cmd,
:startup_info =>
{:sw_flags => Process::SW_HIDE ,
:startf_flags =>
Process::STARTF_USESHOWWINDOW}
).process_id
Process.waitpid(pid)
end
#---------------------------------------
I''ve looked into the win32-process lib, and found there''s no
method to
check if a process is finished, so I must use waitpid. But the waitpid
stop all the other threads, which''re unacceptable for me.
Is there any other way?
Thanks.

Hello Fengfeng, I actually ran into similar issues that your running into. Which prompted me to create this library: http://repos.ruby-im.net/xprocess/ It will allow you to execute processes, as well as capture output, and send input to the sub-process, without blocking any of the Ruby Threads. The interface to the library is pretty simple. I don''t have any docs for the library, but in simplistic terms of an example: my_proc = XProcess.new(cmd) my_proc.execute(my_args) while my_proc.exists? do Thread.pass() # Allow other threads to do their work while this process is working. end # Process has ended, we can parse output of my_proc through my_proc.out.read_lines(), or various other IO methods. hth, Mario On Fri, May 20, 2011 at 12:10 AM, Fengfeng Li <lists at ruby-forum.com> wrote:> Hi, > > Thanks for you reply.

It has call-backs for progress of downloads. alex

Hello Fengfeng, The error your getting, is from the fact that extconf.rb can''t find ruby.h. And given that your running from Windows XP, I''m guessing that your running the One Click Installer for it. You will however, need the Development Environment for the One Click Installer, in order to build the XProcess and various extensions used in making it work. The Development Environment can be found here: http://rubyforge.org/frs/download.php/66888/devkit-3.4.5r3-20091110.7z You will need a utility such as WinRar or 7zip to extract the files. hth, Mario On Wed, Oct 26, 2011 at 10:44 PM, Fengfeng Li <lists at ruby-forum.com> wrote:> Hi, > > Mario Steele wrote in post #999797: > > Hello Fengfeng, > > > > I actually ran into similar issues that your running into.
