i got big problem. have 12 elements same class - "comment". in every button click. i need know how select (eg. 3 of 12) , click button there. is exist selector or something? please give me advice that. $mech->click can take css selector or xpath query argument. if know button want click always third one, use nth-of-type css selector pinpoint it. edit: example using xpath based on op's comments (i haven't tested this). use qq allow variable interpolation inside xpath statement. note have backslash escape occurrences of @ qq doesn't interpret them arrays: my $author = 'xxx'; $mech->click({ xpath => qq(//div[\@class="com" , \@author="$author"]/button) });

in visual basic create application object , start it: gapp = new canoe.application gmeasurement = gapp.measurement gapp.open(arrargs(0), false, false) gmeasurement.start() once application finishes processing data 2 possible scenarios may happen: (i) data file corrupt , (in normal circumstances) allert window raised , (ii) data file ok. in (ii) case can quite application gapp.quit() . in case (i) gapp.quit() not work, since program expects input user (although not see window @ all). question 1 : how can quite process corresponding gapp? quiting in way: each p process in process.getprocesses if p.processname = "canoe32" p.kill() end if next in general bad solution since more instances of canoe32 may run (although in particular case 1 process of binary may run on system). question 2 more elegant solution quit gapp in case has child windows? any comments helpful a possible solution problem use s...
