Hello,

I am using Visual Web Developer 2005 Express. I want to declare a varible,
using Visual Basic as the language and can't get anywhere. For example

Public Test1 as String

I'll get en error saying to change Public to Dim. When I do, it will say
that Test1 is an unused local variable.

Thanks for any help.

God Bless,

and it is unused until you use it somewhere in your code.

Sounds like you are trying to declare a local variable, thus Public is not
an option.
You are also declaring a reference type (String), thus your declaration:

Dim Test1 as String

creates a String object variable that references nothing, hence the second
error.

Try something like this:

Dim xx As New String("THIS IS THE STRING")
 
Actually I'm just playing around trying to learn this stuff. I am
interested in Public variables, becuase I can see a use for them down the
road. Your example worked, but so should mine have worked. I followed the
example in Help. Do you know the syntax for declaring public variables? Do
I need to assign value to variables when they are declared?

Thanks.

It sounds like you're putting that line of code inside a method, making
it a local variable. "Public" only makes sense for an instance or
shared variable.

To declare a public variable, do it within your class body, but outside any
code block.
 
Thanks. That works now. I thought I did that before without success.
