currently users have umask set in ways result in execute permission on regular files, i'd avoid . is there way force files checked in read exceptions? what recommended way handle in cvs? i not sure if best solution, cvswrappers file in cvsroot directory of repo, using commitinfo, commitcheck , commit_prep.pl. if don't have commit_prep.pl, can use one: http://opensource.apple.com/source/cvs/cvs-29/cvs/contrib/commit_prep.pl there quite few examples on web, search commit* files if don't have in repo. note that, post suggests, permission set during first commit of file, after that, you'd need "manually" modify permission on repository itself. how add execute permission file in cvs after it's been checked in? in commit_prep.pl, can clear exec permission using chmod ugo-x , before file committed first time. this solution assumes using linux.

why second 1 of these produce exception while first 1 doesn't? string s = null; messagebox.show(s); messagebox.show(s.tostring()); updated - exception can understand, puzzling bit (to me) why first part doesn't show exception. isn't messagebox, illustrated below. eg : string s = null, msg; msg = "message " + s; //no error msg = "message " + s.tostring(); //error the first part appears implicitly converting null blank string. because cannot call instance method tostring() on null reference. and messagebox.show() implemented ignore null , print out empty message box.

(p.s. have no javascript running on website.) firebug cleans dom tree, if there's syntax bugs in raw source, won't see them in firebug (unless they're bad screws parse tree completely). the regular view-source functionality shows page's source came server. if manipulations of dom after page loaded, won't show in view-source, that's outdated. firebug show live in-memory tree, manipulations included, clean things up.

(this happens quite regularly, seems). there way me identify user located? i'd never heard of term before, , doing little googling confirmed suspicion not common term in usage. my thoughts, reading off of first search result query , you're being asked implement cookie stores users region. can done normal cookie, , can give name "geo" - viola! geo cookie. if you, i'd go stakeholder , find out requirement means. determining user located (without asking directly) can use ip of user, , geo-location service. see know ip address geolocation service more info on that.
