GetDeclaredTypeIid

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

Syntax: GetDeclaredTypeIid(Of T )() As String

T
required The type to query for. Typically an interface declared with the InterfaceId 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 stored in the generated code as a string literal — there is no run-time call.

Useful with any API that takes an interface ID as a string. vbaCastObj does not: it takes the address of a GUID structure.

Example 

Debug.Print GetDeclaredTypeIid(Of stdole.IPicture)()    ' {7BF80980-BF32-101A-8BBB-00AA00300CAB}
