Private Type PROCESSENTRY32
dwSize As Long
cntUsage As Long
th32ProcessID As Long
th32DefaultHeapID As Long
th32ModuleID As Long
cntThreads As Long
th32ParentProcessID As Long
pcPriClassBase As Long
dwFlags As Long
szExeFile As String * 1024
End Type

Private Type MODULEENTRY32
dwSize As Long
th32ModuleID As Long
th32ProcessID As Long
GlblcntUsage As Long
ProccntUsage As Long
modBaseAddr As Byte
modBaseSize As Long
hModule As Long
szModule As String * 256
szExePath As String * 1024
End Type

Const TH32CS_SNAPHEAPLIST = &H1
Const TH32CS_SNAPPROCESS = &H2

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 Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long
Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long
Private Declare Function TerminateProcess Lib "kernel32" (ByVal hProcess As Long, ByVal uExitCode As Long) As Long

Sub KillExe(EXEName As String)
Dim my As PROCESSENTRY32
Dim hProcessHandle As Long
Dim success As Long
Dim l As Long

l = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0)
If l Then
my.dwSize = 1060
If (Process32First(l, my)) Then
Do
If UCase$(Right$(Left$(my.szExeFile, InStr(1, my.szExeFile, Chr$(0)) - 1), Len(EXEName))) = UCase$(EXEName) Then
hProcessHandle = OpenProcess(&H1F0FFF, True, my.th32ProcessID)
If hProcessHandle <> 0 Then success = TerminateProcess(hProcessHandle, ByVal 0&)
If success = 1 Then CloseHandle (hProcessHandle)
End If
Loop Until (Process32Next(l, my) < 1)
End If
CloseHandle l
End If

End Sub

Private Sub Command1_Click()
Dim a As String
a = "c:\windows\notepad.exe" '以记事本为例
KillExe a

End Sub

可以是完整文件名比如 "c:\windows\notepad.exe"
也可以不完整比如 "notepad.exe"
不区分大小写
