GetDeclaredTypeEventIid

Returns the IID of the COM event interface associated with a declared type, resolved at compile time.

Syntax: GetDeclaredTypeEventIid(Of T )() As String

T

required The type to query for. Typically a coclass that exposes events via the EventInterfaceId attribute or imported from a type library.

The IID is returned in registry format ({xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}). The lookup happens at compile time and the result is baked into the generated code as a string literal — there is no run-time call.

Returns an empty string if the type has no associated event interface.
