範例

下列範例會使用 IsFolder 來判斷 Windows 目錄是否為資料夾。 JScript、VBScript 和 Visual Basic 會顯示適當的使用方式。

Jscript：

<script language="JScript">
    function fnIsFolderJ()
    {
        var objShell = new ActiveXObject("shell.application");
        var objFolder2;
        var ssfWINDOWS = 36;
        
        objFolder2 = objShell.NameSpace(ssfWINDOWS);
        if (objFolder2 != null)
        {
            var objFolderItem;
            
            objFolderItem = objFolder2.Self;
            if (objFolderItem != null)
            {
                var bReturn;
                
                bReturn = objFolderItem.IsFolder;
            }
        }
    }
</script>

VBScript：

<script language="VBScript">
    function fnIsFolderVB()
        dim objShell
        
        set objShell = CreateObject("shell.application")
        if (not objShell is nothing) then
            dim objFolder2
            dim ssfWINDOWS
                
            ssfWINDOWS = 36
            set objFolder2 = objShell.NameSpace(ssfWINDOWS)
            if (not objFolder2 is nothing) then
                dim objFolderItem
                        
                set objFolderItem = objFolder2.Self
                if (not objFolderItem is nothing) then
                    dim bReturn
                                
                    bReturn = objFolderItem.IsFolder
                end if
                set objFolderItem = nothing
            end if
            set objFolder2 = nothing
        end if
        set objShell = nothing
    end function
 </script>

Visual Basic：

Private Sub fnIsFolderVB()
    Dim objShell   As Shell
    Dim objFolder2 As Folder2
    Dim ssfWINDOWS As Long
    
    ssfWINDOWS = 36
    Set objShell = New Shell
    Set objFolder2 = objShell.NameSpace(ssfWINDOWS)
        If (Not objFolder2 Is Nothing) Then
            Dim objFolderItem As FolderItem
            
            Set objFolderItem = objFolder2.Self
                If (Not objFolderItem Is Nothing) Then
                    Dim bReturn As Boolean
                    
                    bReturn = objFolderItem.IsFolder
                Else
                    'FolderItem object returned nothing.
                End If
            Set objFolderItem = Nothing
        Else
            'Folder object returned nothing.
        End If
    Set objFolder2 = Nothing
    Set objShell = Nothing
End Sub
