Can anyone explain this........................................

Static variables declared within nonshared methods are per instance: each instance of the type that contains the method has its own copy of the static variable.

I need to create static variables per instance..... in my application... is it possible... Please let me know?

thanks,
Lakshman

yeah you are reading the VB.NET help for static ...

out of curiosity isnt a static variable scoped to an instance really an instance variable ?

public class foo {
    private int bar;

    public void test() {
         bar += 1;
    }
}

this would be scoped to the instance no ?

in vb.net you can say

public function foo() as integer
    Static var As Integer
end function

and it will have the behavior you describe above ...

but you can get nearly identical behavior by saying

public class class2
    private var as integer

    public function foo() as integer
        end function
    end function
end class
