Hola mis hermanos del Mediterraneo,
os dejo un simple código que, usando las funciones externas de la libreria libgio-2.0, cuando se pasa el ratón sobre los íconos de archivo en el Escritorio, devuelve información sobre estos archivos.
Hace falta activar el Componente gb.desktop .
(No se si en la ruta de la Constante "PERCORSO" la palabra "Escritorio" está bien)

Código:

Public Struct IconaFileDesktop
  nome As String
  x As Short
  y As Short
  rt As Rect
End Struct
Private icone As New IconaFileDesktop[]
Private PERCORSO As String = User.home &/ "Escritorio"
Private T As Timer


Public Sub Form_Open()
 
  Dim nomefile, s As String
  Dim ifd As IconaFileDesktop
 
' Carica tutti i file corrispondenti alle icone presenti sulla Scrivania:
  For Each nomefile In Dir(PERCORSO, "*", gb.File)
' Usa con "Extern" alcune funzioni esterne della libreria "libgio-2.0":
    s = EstraeInfo(PERCORSO &/ nomefile)
    If IsNull(s) Then Continue
' Carica nella "Struttura" i dati utili del file individuato dalla funzione "Dir()":
    With ifd = New IconaFileDesktop
      .nome = nomefile
      .x = Val(Scan(s, "*,*")[0])
      .y = Val(Scan(s, "*,*")[1])
' Stabilisce un'area quadrata standard di 48 pixel per ciascuna icona di file individuato:
      .rt = New Rect(.x, .y, 48, 48)
    End With
    icone.Push(ifd)
  Next
 
  T = New Timer As "Tmr"
  T.Delay = 50
  T.Start

End

Public Sub Tmr_Timer()
 
  Dim c As Short
 
  TextArea1.Clear
 
  For c = 0 To icone.Max
' Se le coordinate x,y in pixel correnti in cui si trova il puntatore del mouse rientrano in un'area quadrata caricata, va a vedere a quale icona e file appartiene:
    If icone[c].rt.Contains(Mouse.ScreenX, Mouse.ScreenY) Then
' Mostra alcune caratteristiche del file al quale corrisponde l'icona sorvolata dal puntatore del mouse:
      TextArea1.Text = "== Características del archivo ==\n" &
                       "\nRuta:          " & Stat(PERCORSO &/ icone[c].nome).Path &
                       "\nTamaño:          " & Stat(PERCORSO &/ icone[c].nome).Size & " Byte" &
                       "\nÚltimo acceso:          " & Stat(PERCORSO &/ icone[c].nome).LastAccess &
                       "\nÚltima modificación: " & Stat(PERCORSO &/ icone[c].nome).LastModified &
                       "\nPermisos:          " & Stat(PERCORSO &/ icone[c].nome).Auth &
                       "\nUsuario:          " & Stat(PERCORSO &/ icone[c].nome).User &
                       "\nGrupo:          " & Stat(PERCORSO &/ icone[c].nome).Group &
                       "\nMimetype icono:  " & DesktopMime.FromFile(Stat(PERCORSO &/ icone[c].nome).Path).Type
    Endif
  Next
 
End

Pues sí, si que esta bien la palabra "Escritorio"

Gracias vuott

(No se si en la ruta de la Constante "PERCORSO" la palabra "Escritorio" está bien)

Hola Vuott: en cuanto pueda probare este código que pasaste.
Para la ruta del Escritorio o "percorso della scrivania" puedes usar, como no, código Gambas:

Código:

Private PERCORSO As String = Desktop.GetDirectory("DESKTOP")

Saludos.

Graaazie, tincho.
Olvidé este recurso.
Bravo !
