Captcha Code Case Sensitiveness in Codeigniter -

How to set up a captcha code in uppercase Whether there is even more help in addition to the codeigner for their collision.

To create a captcha with uppercase characters, something like this is needed: 

  $ vals = array ('word' = & gt; strtoupper ('random word'), // here is the captcha code uppercase 'converted to img_path' = & gt; './captcha/ ',' Img_url '= & gt;' http://example.com/captcha/ ',' font_path '= & gt;' ./path/to/fonts/texb.ttf ',' Img_width '= & gt; '150', 'img_height' => 30, 'expiration' => 7200); $ Cap = create_captcha ($ vals); Countercap $ cap ['image'];   
 Of course you may have to check the SQL while checking and it may need to check for the uppercase version of your random word in the database.

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.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow?
