hello
i have to do the following
1.     exec("E:\\TradingTools\\IBController\
\IBControllerStart_customised.bat")
 2.     application = WIN32OLE.new("Broker.Application")

I want to start 1 and then continue doing 2. however when i run it
realtime, the statement 2 waits for statement 1 to be completed which
takes long time. how do i initiate 1 and then withotu waiting goto
statement 2.
        
Wrap #1 in a thread:

Thread.new do
   exec(...)
end
      
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

Fork isn't implemented on Windows.  Try this:

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