Summary: (from MSDN) Invokes the Properties context menu command on a Shell object.

!!!!Sample Code:
!!!!C#

using System;  
    using System.Collections.Generic;
    using System.Runtime.InteropServices;

public class Program
    {
    [DllImport("shell32.dll", SetLastError=true)]
    static extern bool SHObjectProperties(UInt32 hwnd, UInt32 shopObjectType, [MarshalAs(UnmanagedType.LPWStr)] string pszObjectName, [MarshalAs(UnmanagedType.LPWStr)] string pszPropertyPage);
    	public static void Main()
    	{
    		SHObjectProperties(0,2,"C:\\Windows",null);
    		Console.ReadKey();
    	}
    }

!!!!C# Signature:
 [DllImport("shell32.dll", SetLastError=true)]
 static extern bool SHObjectProperties(uint32 hwnd, uint32 shopObjectType, [MarshalAs(UnmanagedType.LPWStr)] string pszObjectName, [MarshalAs(UnmanagedType.LPWStr)] string pszPropertyPage);

(not 100% certain this is correct, need to test)

!!!!VB Signature:
 Declare Function SHObjectProperties Lib "shell32.dll" _
    (ByVal hwnd As UInt32, ByVal shopObjectType As UInt32, _
    <MarshalAs(UnmanagedType.LPWStr)> ByVal pszObjectName As String, _
    <MarshalAs(UnmanagedType.LPWStr)> ByVal pszPropertyPage As String) As Boolean
!!!!User-Defined Types:
Optional Enum used to set shopObjectType for pszObjectName:

Public Enum GetProperties
	SHOP_PRINTERNAME = &H1  '// lpObject points to a printer friendly name
	SHOP_FILEPATH = &H2  '// lpObject points to a fully qualified path+file name
	SHOP_VOLUMEGUID = &H4  '// lpObject points to a Volume GUID
    End Enum

!!!!Alternative Managed API:
Do you know one?  Please contribute it!

!!!!Notes:
Took me forever (okay, less than an hour) to figure out that this function failed with Integers or Longs and it wanted UInt32 for hwnd and shopObjectType.

!!!!Tips & Tricks:
Please add some!

!!!!Sample Code:
!!!!!VB

Sub Main()
        ShowProp("C:\boot.ini")
	'needed to keep the properties window open (window is bound to current application handle)
        Console.ReadKey()
    End Sub

Public Enum GetProperties
        SHOP_PRINTERNAME = &H1  '// lpObject points to a printer friendly name
        SHOP_FILEPATH = &H2  '// lpObject points to a fully qualified path+file name
        SHOP_VOLUMEGUID = &H4  '// lpObject points to a Volume GUID
    End Enum

Private Declare Function SHObjectProperties Lib "shell32.dll" _
    (ByVal hwnd As UInt32, ByVal shopObjectType As UInt32, _
    <MarshalAs(UnmanagedType.LPWStr)> ByVal pszObjectName As String, _
    <MarshalAs(UnmanagedType.LPWStr)> ByVal pszPropertyPage As String) As Boolean

Public Function ShowProp(ByVal filename As String, Optional ByVal page As String = "") As Boolean
        If page = String.Empty Then
            page = 0
        Else
            page = page
        End If
        ShowProp = SHObjectProperties(0, GetProperties.SHOP_FILEPATH, filename, String.Empty)
    End Function
