首先通過CreateToolhelp32Snapshot函數創建一個進程的快照，然后通過調用Process32First使用快照返回的句柄對進程進行遍歷，相關的信息存放在PROCESSENTRY32結構類型的實例中，然后顯示出來。
Winxp+vb6+sp6
代碼如下：

Private Declare Function Process32First Lib "kernel32" (ByVal hSnapshot As Long, lppe As PROCESSENTRY32) As Long
Private Declare Function Process32Next Lib "kernel32" (ByVal hSnapshot As Long, lppe As PROCESSENTRY32) As Long
Private Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long
Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, _
ByVal blnheritHandle As Long, ByVal dwAppProcessId As Long) As Long
Private Declare Function TerminateProcess Lib "kernel32" (ByVal ApphProcess As Long, _
ByVal uExitCode As Long) As Long
