Hi!
To pass a user-defined type as parameter of public method in a COM object, you must use early binding to COM object and declare UDT as Public in Public class module. UDT always passed by reference. You can look at sample of passing UDT in article "Q185700 - HOWTO: Remote User-Defined Types".

>I want to use a type as a parameter in a dll function. I have scoured the MSDN and I have tried it several ways. I have made the function private, I have declared the type in a public object module...

*** In the dll I want to be able to do something like this:
>
>Public type tLocal ' or Private
>  name as string
>  x as integer
>  y as integer
>end type
>
>Public function GetLocation(byref LX as tLocal) ' or Private
>    LX.Name = "Zone Two"
>    LX.x = 12
>    LX.y = 55
>End Function

>private sub foo
>    dim MyType as tLocal
>    set ox = mydllproj.mydllclass
>
>    ox.GetLocation MyType
>
>    debug.print MyType.Name
>    debug.print MyType.x
>    debug.print MyType.y
>
>end sub

Thanks in Advance.
