有没有办法通过PID 获取进程名

窗体上添加一个 text 一个按钮 只需在text中输入进程名单击一下按钮 就可以
只需要三个api
Private Declare Function CreateToolhelp32Snapshot Lib "kernel32" (ByVal dwFlags As Long, ByVal th32ProcessID As Long) As Long
Private Declare Function Process32First Lib "kernel32" (ByVal hSnapshot As Long, lppe As PROCESSENTRY32) As Long

Private Type PROCESSENTRY32
dwSize As Long
cntUsage As Long
th32ProcessID As Long
th32DefaultHeapID As Long
th32ModuleID As Long

th32ParentProcessID As Long
pcPriClassBase As Long
dwFlags As Long
szExeFile As String * 1024
