How many instances of a shared variable are there

[SamSpade]

If I define a variable in a module there is only one instance of the
variable for all instances of the class.

If I define a variable within a class there is an instance of the variable
for each instance of the class.

What happens if the variable in the class is defined as shared? How many
instances of the variable are there.

Thanks

One per process that uses the class library.

SamSpade,
As the other's have stated, there is one per process.

However! if you apply the System.ThreadStaticAttribute to the Shared
variable (or Module variable) you will have one per thread in your process.

Hope this helps

One per process that uses the class library.

I believe it's actually one per appdomain.
