What specifies a variable's name and date type

const feet_per_mile = 5280
distance = 8.5
print "the distance is "+distance "+miles or+" distance*feet_per_mile+" feet."

You need to assign a default value to your variable, otherwise it's just declared and not initialized.
Example (in C#):
int numericValue; Here the variable numericValue has been declared as an integer
int numericValue = 11; and here the variable has been declared and initialized as an integer with the value 11.

If You cannot enable 802.1x authentication on computers running Windows 2000 because support for 802.1x is not provided by default in Windows 2000. Therefore, the associated user interface (the Authentication tab) does not appear in the Network Connection Properties dialog box.

A supported feature that modifies the product's default behavior is now available from Microsoft, but it is only intended to modify the behavior that this article describes. Apply it only to systems that specifically require it. This feature may receive additional testing. Therefore, if the system is not severely affected by the lack of this feature, we recommend that you wait for the next Windows 2000 service pack that contains this feature.

After you apply this update, follow these steps to enable 802.1x authentication:

1. Installing the hotfix installs the 802.1x service in the disabled state. To change the Wireless Configuration service startup to Automatic: Right-click My Computer, and then click Manage. Click Services and Applications, and then click Services. Set the Startup value for the service to Automatic, and then start the service.
2. Open Network Connections by clicking Start, pointing to Settings, clicking Control Panel, and then double-clicking Network Connections.
3. Right-click the wireless connection for which you want to enable or disable 802.1x authentication, and then click Properties.
4. On the Authentication tab, do one of the following:
   • To enable 802.1x authentication for this connection, click to select the Enable network access control using IEEE 802.1x check box. By default, this check box is selected.
   • To disable 802.1x authentication for this connection, click to clear the Enable network access control using IEEE 802.1x check box.
5. In the EAP type box, click the Extensible Authentication Protocol type that is to be used with this connection.
6. If you click Smart Card or other Certificate in the EAP type box, you can configure additional properties if you click Properties and then follow these steps in Smart Card or other Certificate properties:
   • To use the certificate that is located in the certificate store on your computer for authentication, click Use a certificate on this computer.
   • To verify that the server certificate that is presented to your computer is still valid, click to select the Validate server certificate check box, specify whether to connect only if the server is located in a particular domain, and then specify the trusted root certification authority.
   • To use a different user name when the user name in the certificate is different from the user name in the domain to which you are logging on, click to select the Use a different user name for the connection check box.
7. If you click Protected EAP (PEAP) in the EAP type box, your Windows user name and password are used for authentication.
8. To specify whether the computer should try authentication on the network if a user is not logged on, if the computer or user information is not available, or both, follow these steps:
   • To specify that the computer try authentication on the network if a user is not logged on, click to select the Authenticate as computer when computer information is available check box. By default, this check box is selected.
   • To specify that the computer try authentication on the network if user information or computer information is not available, click to select the Authenticate as guest when user or computer information is unavailable check box.

Hi,
I'm assuming you are referring to declaring variables in Procedural programming languages such as Java. Variables need to be declared for several different reasons, some of which include helping the computer reserve space in memory for variables to be stored and it also plays a part in the various stages of converting the source code, i.e. the code that you type in VB or Java, into machine code which is a series of binary digits that the computer can actually understand. It helps the computer in debugging the code for errors. In the first stage of code conversion, lexical analysis, information about the variable names is stored. In the next stage, Syntax analysis, the code is checked to be grammatically correct according to the rules of Backus Naur Form, i.e. if a key word such as PRINT is typed in as PLINT the computer will treat this as a variable name and since no information about this variable name has been entered in the lexical analysis stage it knows that an error has been made.
Hope this helps!

well there is not much difference there.the difference is in the data types not in declaration

if this is vb 6 then you should be able to access the other variable by using the other forms name so if you are in form1 and want to access a variable in form2

form2.variable_name

and visa versa

If this is another language then it may differ

Syntactically, Pascal is much more Algol-like than C. English keywords are retained where C uses punctuation symbols — Pascal has and, or, and mod where C uses &&, ||, and % for example. However, C is actually more Algol-like than Pascal regarding (simple) declarations, retaining the type-name variable-name syntax which Pascal abandoned to allow for (easily read) complex type expressions and a better perceived clarity in educational situations.

1. IDE is Integrated Development Environment
2.With VB 6, one can develop applications with feature rich GUIs (Graphical User Interface). Many varieties of general purpose software can be created with little effort, including, but not limited to, image editing software, text editor and database applications.
3.Windows Application Template
-----------------------------------------------------
Used to create Windows-based applications that run locally on users' machines. You can build anything from a simple single-window tool like Windows Calculator to a complete application with multiple windows and advanced capabilities.

Class Library Template
-----------------------------------------
Used to create reusable classes or components that can be shared with other projects.

Console Application Template
----------------------------------------------------
Used to create command-line applications, programs that run from a Windows command prompt and have no visual interface.

My Movie Collection Starter Kit Template
-------------------------------------------------------------------------
Used to create the pre-built My Movie Collection sample application, which you can customize to meet your own needs. For more information, see Starter Kits: Getting Up and Running Quickly.

4.FormShaper lets you change the shape that windows draws your forms. You can have rectangles, rounded rectangles, ellipses, polygons and any combination of the above! Even save the shapes to a file for use in other projects! See readme.txt in the zip file for more details

5.Description
Used at script level to force explicit declaration of all variables in that script.
Syntax
------------
Option Explicit
Remarks
----------------
If used, the Option Explicit statement must appear in a script before any procedures.
When you use the Option Explicit statement, you must explicitly declare all variables using the Dim, Private, Public, or ReDim statements. If you attempt to use an undeclared variable name, an error occurs.
--------------------------------------------------------------------------------

Use Option Explicit to avoid incorrectly typing the name of an existing variable or to avoid confusion in code where the scope of the variable is not clear.
