Assuming you are asking how to do this by hand and not from a program, see below. If you want to write a program you'll need to look on MSDN for the various ways of setting and retrieving environment variables.
Set your environment variables into the registry using REG.EXE from the command line.
Variables for the Current User are stored in HKEY_CURRENT_USER (HKCU) and for All Users in HKEY_LOCAL_MACHINE (HKLM). The registry locations are:
You'll need to know the type of data you want to store. Choices are:
So to create an environment variable named "Fred" with a value of "1234" do this:
REG ADD HKCU\Environment /v Fred /d 1234 /t REG_SZ
/v is the variable, /d is the data and /t is the type. Use REG_EXPAND_SZ if you want to include existing environment variables (e.g. %system%) and remember to double the %'s (i.e. \d %%system%%\mypath.
Retrieve your setting with:
REG QUERY HKCU\Environment /v FRED
NOTE: This will not update the current environment, neither in the current command window nor in other windows (of any type). ou must logout and login for the changes to be picked up r you'll need to compile the following code-lette which I got from the MSDN reference:
#include
int main(int argc, char* argv[])
{
DWORD_PTR dwReturnValue;
SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, 0,
(LPARAM) "Environment", SMTO_ABORTIFHUNG,
5000, &dwReturnValue);
return 0;
}
Type REG at a command prompt for more details.
It's an environment variable that stores the paths of commonly used executables. All OSes have this set, even on Windows.
It's called Path (use the SET command to access it).
1. install JdK 2. include JDK_HOME/bin in your PATH environment variable
The name of your login shell is set when you log in - check the $SHELL environment variable. Note that this is a changeable environment variable so it isn't always accurate. You could also use the 'finger' command or 'grep' through the password file to see what your login shell environment will be set to. However, if you are in a subshell or child shell, you will need to check on the shell environment with the 'ps' command to see what the shell currently running might be.
A set of data with one variable is a net-graph
To set up a Wal-Mart wedding registry you can either go to any Wal-Mart store and visit the customer service station. They will set you up with everything you need. Or you can visit Walmart.com. On the front page click on the "Registry" tab at the top of the page. Then select "Create Wedding Registry". From here you will have to set up a Wal-Mart account, if you already do not have one, after that it's as easy as selecting items from the website and adding them to your registry. After creating a registry online, you will also be able to go to any physical Wal-Mart store and add items to the registry.
By carefully editing the /etc/sudoers file using visudo.Note: before that set environment variable EDITOR to your favourite text-editor, for example:export EDITOR=/usr/bin/mcedit
A honeymoon registry involves collecting gifts from wedding guests. There are online web services that can help one set up a honeymoon registry, such as Honeyfund and Honeymoon Wishes.
You set up a Macy's bridal registry by going to their official site and registering. You pick the items you want and add them to your list. Then you give out the list to all attendees.

The observed values of a variable form the data set. Not sure where "element" fits into it.
You need to set The CLASSPATH variable which is an argument set on the command-line that tells the Java Virtual Machine where to look for user-defined classes and packages in Java programs. Syntax is java -classpath "path to the packages". Set the PATH variable if you want to be able to conveniently run the Java 2 SDK executables (javac.exe, java.exe, javadoc.exe, etc.) from any directory without having to type the full path of the command. To set the PATH permanently, add the full path of the j2sdk1.4.2_version\bin directory to the PATH variable. -sravyaa
