如何编写vb的pid程序

1、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apiPrivate Declare Function CreateToolhelp32Snapshot Lib "kernel32" (ByVal dwFlags As Long, ByVal th32ProcessID As Long) As LongPrivate Declare FunctionProcess32FirstLib "kernel32" (ByVal hSnapshot As Long, lppe AsPROCESSENTRY32) As LongPrivate Declare FunctionProcess32NextLib "kernel32" (ByVal hSnapshot As Long, lppe AsPROCESSENTRY32) As LongPrivate TypePROCESSENTRY32

3、Const TH32CS_SNAPHEAPLIST = &H1Const TH32CS_SNAPPROCESS = &H2Const TH32CS_SNAPTHREAD = &H4Const TH32CS_SNAPMODULE = &H8Const TH32CS_SNAPALL = (TH32CS_SNAPHEAPLIST Or TH32CS_SNAPPROCESS Or TH32CS_SNAPTHREAD Or TH32CS_SNAPMODULE)Const TH32CS_INHERIT = &H80000000

5、l = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0)If l Thenmy.dwSize = 1060End IfIf (Process32First(l, my)) Then '遍历第一个进程Doi = InStr(1, my.szExeFile, Chr(0)) '返回chr(0)在各个进程中出现的位置mName = LCase(Left(my.szExeFile, i - 1)) '返回小写的（返回i-1的前n个字符，即正确的名称）If mName = a Then
