Can I get an image's file size and mime-type via JavaScript (FireFox/Gecko/Mozilla only) -

Can I get an image file size and mime-type via Javascript I inspect all the images in a document I am writing a script to do I will run scripts in Firefox so that specific solutions for Firefox (undocumented / non-standard / otherwise) are absolutely acceptable. I can use jQuery if necessary.

You can request a head XHR which will tell you the size of the file , Provided that these images are on your domain.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.
