Form中的代碼
Private Sub Command1_Click()
App.TaskVisible = False ''任務欄隱藏
Call HideCurrentProcess ''進程隱藏
End Sub
新建一個模塊，代碼如下：
''-------------------------------------------------------------------------------------
''模塊名稱：modHideProcess.bas
''
''模塊功能：在 XP/2K 任務管理器的進程列表中隱藏當前進程
''
''使用方法：直接調用 HideCurrentProcess()
''
''模塊作者：檢索自互聯網，原作者不詳。
