reverse engineering - Possible to customize camera firmware? -

-

I have a firmware update for my camera, will it be theoretically possible

delete it, Understand and customize it?

Even if it has to be unencrypted, you know something about the layout of the file - there are not many chips that can execute the correct code from the reset vector. After that, not is an easy task to test the dysfunctioned binary back in a high level source code, of course there is definitely something to take back that you can easily understand and modify. .. Good luck!

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.
