Wrap #1 in a thread:

Thread.new do

Wouldn't help. This is #exec and not #system - the process does not
wait, it is completely replaced and "application =
WIN32OLE.new("Broker.Application")" is never executed.

You rather want fork.

fork do
  exec ...
end

Cheers

Wrap #1 in a thread:

Thread.new do
   exec(...)
end

use.inject do |as, often| as.you_can - without end

Fork isn't implemented on Windows. Try this:

system("start E:\\TradingTools\\IBController\\IBControllerStart_customised.bat")
application = WIN32OLE.new("Broker.Application")

Oops, you're quite right, I was thinking of #system.

Maybe #system would be right for the OP:

   Thread.new do
     system("...")
   end

   application = ..

This is AFAIK platform independent, since it doesn't (explicitly, anyway) use #fork or "start".

Maynot help you much but in Perl world I used IPC::Run module to do
exactly this. Not sure if there is a similar module in RubyLand.

Unless you are using cygwin. Sorry, I keep forgetting that the other
Windows based versions do not have it. Thanks for correcting me!

Try this:

system("start E:\\TradingTools\\IBController\\IBControllerStart_customised.bat")
application = WIN32OLE.new("Broker.Application")

Kind regards

i tried that. it does not work for me. it waits
   Thread.new do
                   system("start E:\\TradingTools\\IBController\
\IBControllerStart_customised.bat")
    end
to get completed before going and doing this
application = WIN32OLE.new("Broker.Application")

Oops, you're quite right, I was thinking of #system.

Maybe #system would be right for the OP:

Thread.new do
system("...")
end

application = ..

This is AFAIK platform independent, since it doesn't (explicitly,
anyway) use #fork or "start".
