我也试了,没成功
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
ShellExecute 0&, vbNullString, App.Path + "\显示桌面.scf", vbNullString, vbNullString, vbNormalFocus
直接点击显示桌面.scf可以
