Old style VB Declare statements

[Water Cooler v2]

OK, I know about PInvoke and I know about "Auto", but here's what I do
not know for sure.

Are old style VB signatures for Win32 API (with the changes in the
data-types, of course) still workable (directly portable) to VB.NET?

Yes and no. .NET provides some more specific types such as 'IntPtr' and
marshalling attributes. Thus it's often preferrable to re-check the
declarations with the C function prototypes.
