帮帮手精简一下VB代码

Option Explicit
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 Declare Function Process32Next Lib "kernel32" (ByVal hSnapShot As Long, lppe As PROCESSENTRY32) As Long
Private Const TH32CS_SNAPPROCESS = &H2&
Private Type PROCESSENTRY32
dwSize As Long
cntUsage As Long
th32ProcessID As Long
aaa As String * 24
szExeFile As String * 260
End Type
Function GetPsPid(sProcess As String) As Long
Dim lSnapShot As Long
Dim lNextProcess As Long
Dim tPE As PROCESSENTRY32
lSnapShot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0&)
tPE.dwSize = Len(tPE)
lNextProcess = Process32First(lSnapShot, tPE)
Do While lNextProcess
If LCase$(sProcess) = LCase$(Left(tPE.szExeFile, InStr(1, tPE.szExeFile, Chr(0)) - 1)) Then
GetPsPid = tPE.th32ProcessID
Exit Function
End If
lNextProcess = Process32Next(lSnapShot, tPE)
Loop
End Function
Private Sub Command1_Click()
Print GetPsPid(Text1.Text)
End Sub
