Pointer to a structure?

[Icyculyr]

I'm doing this:
SendMessage(hWnd, LVM_GETITEM, Nothing, @), which @ should be a pointer to a structure called LVITEM, which I've made, but how do I make a pointer to a structure in Visual Basic .NET 2008??

IE:

Dim liItem As New LVITEM()

SendMessage(hWnd, LVM_GETITEM, Nothing, Pointer(liItem))

How do I do this?

Cheers
