Any solution for that?

According to that I need to call it in unicode() :

I am inserting 'this' pointer into a map
Does it cause a segmentation fault
My code is
client->commandHandlerMap.insert(std::pair<CommandType , CommandHandler*>(CommandType::OrderBookCommandType , this));
I am doing this inside the member function of a derived class of CommandHandler
I would assume that client is not initialized or has an invalid pointer.

Ogre::any_cast<std::map<Rail>::iterator>
It takes Ogre::any_cast<std::map<Rail> and says too few arguments etc. How can I fix it (other than obvious typedef aliasing)?
The problem is that std::map takes at least two template arguments - the key type and the value type. Currently you have std::map<Rail>. What are you mapping from Rail to? For example, this would be okay if your iterators are for a std::map that maps from Rail to int (assuming Rail is not a deduced type):
Ogre::any_cast<std::map<Rail,int>::iterator>(some_any_object)

How can i write this line of code in Coffeescript? Thank's
window.scrollY >= origOffsetY ? navbar.classList.add('navbar-fixed-top') :
navbar.classList.remove('navbar-fixed-top');
I try this, but doesn't work.
if window.scrollY >= origOffsetY then navbar.classList.add('navbar-fixed-top') else navbar.classList.remove('navbar-fixed-top')
Your coffeescript compiles to :
if (window.scrollY >= origOffsetY) {
navbar.classList.add('navbar-fixed-top');
} else {
navbar.classList.remove('navbar-fixed-top');
}
This seems pretty OK for me.

[a-zA-Z0-9-_]{3,} this is my currently using regular expression in login page. I would like to allow space in the regexp. How can i do it? I'm lack of knowledge in RegExp.
This is just a character class, so just add space at the end of the class: [a-zA-Z0-9_ -]{3,}
How about:
[a-zA-Z0-9-_\s]{3,}
This will allow all forms of whitespace...
