範例

下列範例會使用 Count 來擷取 Windows 資料夾中的專案計數。 JScript、VBScript 和 Visual Basic 會顯示適當的使用方式。

Jscript：

<script language="JScript">
    function fnFolderItemsCountJ()
    {
        var objShell = new ActiveXObject("shell.application");
        var objFolder;
        var ssfWINDOWS = 36;
        
        objFolder = objShell.NameSpace(ssfWINDOWS);
        if (objFolder != null)
        {
            var objFolderItems;
            
            objFolderItems = objFolder.Items();
            if (objFolderItems != null)
            {
                var nCount;
                
                nCount = objFolderItems.Count;
                alert(nCount);
            }
        }
    }
</script>

VBScript：

<script language="VBScript">
    function fnFolderItemsCountVB()
        dim objShell
        
        set objShell = CreateObject("shell.application")
        if (not objShell is nothing) then
            dim objFolder
            dim ssfWINDOWS
                
            ssfWINDOWS = 36
            set objFolder = objShell.NameSpace(ssfWINDOWS)
            if (not objFolder is nothing) then
                dim objFolderItems
                        
                set objFolderItems = objFolder.Items()
                if (not objFolderItems is nothing) then
                    dim nCount
                    
                    nCount = objFolderItems.Count
                    alert(nCount)
                end if
                set objFolderItems = nothing
            end if
            set objFolder = nothing
        end if
        set objShell = nothing
    end function
 </script>

Visual Basic：

Private Sub fnFolderItemsCountVB()
    Dim objShell   As Shell
    Dim objFolder  As Folder
    Dim ssfWINDOWS As Long
    
    ssfWINDOWS = 36
    Set objShell = New Shell
    Set objFolder = objShell.NameSpace(ssfWINDOWS)
        If (Not objFolder Is Nothing) Then
            Dim objFolderItems As FolderItems
            
            Set objFolderItems = objFolder.Items
                If (Not objFolderItems Is Nothing) Then
                    Dim nCount As Integer
                    
                    nCount = objFolderItems.Count
                    Debug.Print nCount
                End If
            Set objFolderItems = Nothing
        End If
    Set objFolder = Nothing
    Set objShell = Nothing
End Sub
