Call Up Windows Shell Features

Here's a little routine that provides a quick and dirty way to call up some of the more oddball features of the Windows shell. It works by emulating user keystrokes, so you'll need to modify the keys for non-English versions. Simply paste this code into a standard module and pass the Enum of choice:
 
Private Declare Sub keybd_event Lib "user32" (ByVal bVk As _
	Byte, ByVal bScan As Byte, ByVal dwFlags As Long, _
	ByVal dwExtraInfo As Long)

Public Enum SystemKeyShortcuts
	ExplorerNew = &H45	' Asc("E")
	FindFiles = &H46		' Asc("F")
	MinimizeAll = &H4D	' Asc("M")
	RunDialog = &H52		' Asc("R")
	StartMenu = &H5B		' Asc("[")
	StandbyMode = &H5E	' Asc("^") -- Win98 only!
End Enum

Public Sub SystemAction(VkAction As SystemKeyShortcuts)
	Const VK_LWIN = &H5B
	Const KEYEVENTF_KEYUP = &H2
	Call keybd_event(VK_LWIN, 0, 0, 0)
	Call keybd_event(VkAction, 0, 0, 0)
	Call keybd_event(VK_LWIN, 0, KEYEVENTF_KEYUP, 0)
End Sub
