Hello viraj,
As for classes, it's suggested to start a class name with a capital:
class MyBestClass {
...
}
In some languages (I can't remember if it is Java, or Javascript, or
both) the first letter should be lowercase, such as:
myBestClass
Cheers,

Tedd-
Java has classes listed with an Uppercase. It could be JS you're thinking of
but I'm not sure. Functions (except constructors) and variables have the
lowerUpperCamelCase notation.

One of the best features of standards is that there are so many to
choose from. Likewise with coding styles, there are nearly as many as
there are coders. If you are working by yourself, pick something and
stick with it. If you are working in a group, or are employed to write
code, there may be requirements agreed upon or required in that
environment. You may not find out about them until your first code
review, but be assured, you will eventually be told about them.

As for functions and class methods, there are lots of people who name
them like this:
function the_greatest_function_in_the_world () {
...
}
Maybe it's readable and great, but I have a little problem: I'm using
a screenreader, so the word "underscore" (and its Russian equivalent)
is too long for me. So I prefer
function TheGreatestFunctionInTheWorld () {
...
}
However, just discussed it with my wife. She prefers the same method
as me, though she doesn't use any screenreading software for
developing.
Hello All
First thanks for all suggestions, I find some document from 2003 year
and plane to use this standard everybody who what can see on next link
http://www.dagbladet.no/development/phpcodingstandard/

We use a signature pad and dll from m2sys for something similar to
this. It captures the signature, then creates a hash of the signature
to store in the db.
The only mobile app that I know that uses it is Square which is a
mobile payment system.
