Jscript：

<script language="JScript">
    function fnModifyDateGetSetJ()
    {
        var objShell = new ActiveXObject("shell.application");
        var objFolder2;
        var ssfWINDOWS = 36;
        
        objFolder2 = objShell.NameSpace(ssfWINDOWS);
        if (objFolder2 != null)
        {
            var objFolderItem;
            
            objFolderItem = objFolder2.ParseName("NOTEPAD.EXE");
            if (objFolderItem != null)
            {
                var szReturn;
                
                szReturn = objFolderItem.ModifyDate;
                objFolderItem.ModifyDate = "01/01/1900 6:05:00 PM";
            }
        }
    }
</script>

VBScript：

<script language="VBScript">
    function fnModifyDateGetSetVB()
        dim objShell
        
        set objShell = CreateObject("shell.application")

            dim objFolder2
            dim ssfWINDOWS
                
            ssfWINDOWS = 36
            set objFolder2 = objShell.NameSpace(ssfWINDOWS)
            if (not objFolder2 is nothing) then
                dim objFolderItem
                        
                set objFolderItem = objFolder2.ParseName("NOTEPAD.EXE")
                if (not objFolderItem is nothing) then

            set objFolder2 = nothing
        end if
        set objShell = nothing
    end function
 </script>

Visual Basic：

Private Sub fnModifyDateGetSetVB()
    Dim objShell   As Shell
    Dim objFolder2 As Folder2
    Dim ssfWINDOWS As Long
    
    ssfWINDOWS = 36
    Set objShell = New Shell

        If (Not objFolder2 Is Nothing) Then
            Dim objFolderItem As FolderItem
            
            Set objFolderItem = objFolder2.ParseName("NOTEPAD.EXE")
                If (Not objFolderItem Is Nothing) Then

                    szReturn = objFolderItem.ModifyDate
