Hi all
I'm using VB.net. I need to define an object of type iShellFolder (since
I have to call ShGetDesktopfolder API in Shell32.dll). I've created
interop.Shell32.dll adding a reference to Shell32.dll, but I can't find any
definition of iShellFolder under new Shell32 namespace.

Must I define the interface manually? Should I use a module within interface
definition:

Interface iShellFolder
Function ParseDisplayName(ByVal IntPtr As Long, bla bla bla ) as
long
Function...
End Interface

or should I use tlbimport, edit it manually (how?) and... what?

I've read a lot of documents but I can't find a complete walktrough, can
someone help me please?

Thanks in advance.
Nicola

Yes, you need to do this yourself. Here is my version. I hasn't been fully
tested but seems to work for the bits I use . Note that you will need to
define SHCONTF and STRRET (can be found in MSDN) and modify parameters as
required.
