Lee J. Wein #2 / 4	Desktop Icons Position Using API? LVM_GETITEMPOSITION is a message normally used on ListView controls. Has someone told you you can use it on the desktop? I'm not sure you can, but even if you could, the first argument of the SendMessage function call should be the window handle of the ListView, in your case the handle to the desktop, which you would have to retrieve with the GetDesktopWindow function call.

How are you passing the pointapi struct? VB doesn't allow passing structures byval to an API function.

VB doesn't allow passing >structures byval to an API function. There are several different ways to declare and use the same function. A difference in declaration infers a difference in use in the call also. I prefer (..., lParam as Any) for SendMessage, as it's the most universal. This allows passing pointers (UDT's), pointers to strings (Byval somestring$) and values (Byval somevalue&) Bart.
