[ reply ]   2011-10-17 20:55 I can confirm that setting the argument to S fixes the issue and lets me run a program normally when I specify both app_name and command_line. Patch will follow. By: Daniel Berger RE: frozen string on CreateProcess? [ reply ]   2011-03-25 03:59 I *think* this might be happening because of the way the CreateProcess function is declared in windows-pr. It's set to "P" but it looks like it should be set to "S". I need to look into it more. I'll keep you posted. Regards, Dan By: Pok Lau frozen string on CreateProcess? [ reply ]   2011-03-24 01:08 I tried using Process.create to start a sub process to execute a batch file in a particular directory. This is what I did: proc_info = Process.create( :app_name => ENV['SystemRoot'] + "\\system32\\cmd.exe", :command_line => "C:\\some_bin\\some_cmd.bat some_parameter", :cwd => "C:\\some_workspace") The execution failed as: (eval):3:in `call': can't modify frozen string (TypeError) from (eval):3:in `CreateProcess' from C:/Ruby187/lib/ruby/gems/1.8/gems/win32-process-0.6.5/lib/win32/pro cess.rb:873:in `create' from some_process_script.rb:11 Did I miss something here?
