This is rajib a ruby nub…e . I was looking for some serious gui programming on GUI in ruby when i came upon the Rubywebdialog … a wonderful approach for universal GUI. I rushed througn the instruction etc in [http://www.erikveen.dds.nl/rubywebdialogs/index.html](http://www.erikveen.dds.nl/rubywebdialogs/index.html)… # And tried to run rwdhelloworld.rbw. But some strange error is appearing … can any one point me to my mistakes # C:\rubyexample\rubywebdialogs\>ruby rwdhelloworld.rbw Looking for default browser… Starting the browser… C:/DOCUME~1/ri004902/LOCALS~1/Temp/tar2rubyscript.d.2692.1/tmp.ear2rubyscript.f. 11594.tar/ev/rwd.rb:1175:in `system': Insecure operation - system (SecurityError ) from C:/DOCUME~1/ri004902/LOCALS~1/Temp/tar2rubyscript.d.2692.1/tmp.ear2 rubyscript.f.11594.tar/ev/rwd.rb:1175:in `initialize’ from C:/DOCUME~1/ri004902/LOCALS~1/Temp/tar2rubyscript.d.2692.1/tmp.ear2 rubyscript.f.11594.tar/ev/rwd.rb:1160:in `initialize' from C:/DOCUME~1/ri004902/LOCALS~1/Temp/tar2rubyscript.d.2692.1/tmp.ear2 rubyscript.f.11594.tar/ev/rwd.rb:802:in `serve’ from C:/DOCUME~1/ri004902/LOCALS~1/Temp/tar2rubyscript.d.2692.1/tmp.ear2 rubyscript.f.11594.tar/init.rb:3 from rwdhelloworld.rbw:538 from rwdhelloworld.rbw:503:in `newlocation' from rwdhelloworld.rbw:439:in `newlocation’ from rwdhelloworld.rbw:420:in `newlocation' from rwdhelloworld.rbw:439:in `newlocation’ from rwdhelloworld.rbw:503:in `newlocation’ from rwdhelloworld.rbw:533 Thanks ---

> 11594.tar/ev/rwd.rb:1175:in `system’: Insecure operation - system > (SecurityError) If you set the environmental variable RWDBROWSER to nothing (that’s _not_ the same as unset…), you should be able to start the application, after which you should start the browser by hand and navigate to the given address. I definitely need to update RubyWebDialogs… If I only had time… (I’m currently working on a new version of RubyScript2Exe. The one with support for directories.) gegroet, Erik V. - [http://www.erikveen.dds.nl/](http://www.erikveen.dds.nl/) ---

The simplest solution could be installation of ruby 1.8.2, though I haven’t tried yet. # see also “7. Known Issues” in RubyWebDialogs. > # 11594.tar/ev/rwd.rb:1175:in `system’: Insecure operation - system (SecurityError ) > > Did you do something else too… Nothing, but I didn’t try rubyhelloworld.rbw. I tried rwdpanels.tar.gz with ruby 1.8.5 (stable-snapshot) on Fedora Core 5. (1). download rwdhelloworld.tar.gz (2). expand rwdhelloworld.tar.gz (3). change ev/rwd.rb in tmp.ear2rubyscript.f.11594.tar , the directory created at 2 line 59: $SAFE=0 (4). run init.rb in tmp.ear2rubyscript.f.11594.tar That’s all. I found another solution to delete the 1175th line in ev/rwd.rb while trying rwdhelloworld.tar.gz Without that line, RWDServer fail to start the browser, and init.rb tell the URL of “hello world”. if you go to the URL, you can watch “hello world”. # note that I tried not .rbw but .tar.gz . ---

Command =\> “C:\Program Files\Mozilla Firefox\firefox.exe” “[http://localhost:7702/](http://localhost:7702/)” The browser has terminated. * * * If you can throw some light … will be great… thanks Hayato and Erik. I will take it further. ---
