What is the difference between these declarations:
Dim strMyData() as string

and

Dim strMyData as string()

Don't be so sure. I still think it is just depracted syntax.

Try this:

Dim s as string
Intellisense says for s = "Dim s as string"

Dim s() as string
Intellisense says for s = "Dim s() as string"

Dim s as string()
Intellisense says for s = "Dim s() as string"

Also this will compile:
Dim s as string()
Redim s(10)

And this won't:
Dim s a string
Redim s(10)

Dim strMyData() as string

means that you are initializing an array of strings

Dim strMyData as string()

is simply wrong syntax. The open and close parentheses at the end of the
statement signifies that you are providing reference to the class
through the default constructor of the class but since you are not using
it with the New keyword it is wrong syntax.

You can use Dim strMyData as New SomeClass(), which means that you are
creating an instance called strMyData and initializing the object
through the default constructor of the class.

I don't think it's deprecated. It's only an alternative that works and that
will work for forseeable future. VB6 only supported the 'Dim X() As Y'
syntax.

You might want to inform MSFT that syntax is wrong since they
use that syntax in the documentation to explain creating an array!

(See 'New keyword' in VB.Net help)

There is no parameterless constructor for the String class:

strMyData = New String()

That syntax is wrong, which indicates that there is no 'default constructor'
for the String class.

Following primative types with parentheses is another valid data type as
evidensed by:

Dim a As String() = {"X", "Y"}
Dim b As Integer() = {1, 2}

The parentheses indicate the Array class is used to build a strongly typed
array. (Note the array class also has no 'default constructor' and the
desired type is a requirement of the shared CreateInstance method.)
