添加一个ListBox和一个按钮

'上为函数声明，在此程序中EnumProcessModules为非必要，枚举进程路径，并不需要去枚举进程的模块。
Dim cbNeeded As Long, cbNeeded2 As Long, ProcessIDs(1 To 255) As Long
Dim lRet As Long, ModuleName As String, hProcess As Long
Const PROCESS_QUERY_INFORMATION = &H400
Const PROCESS_VM_READ = &H10
Dim DeskW As Long, DeskH As Long
Private Sub Command1_Click()
Dim ProcessCount As Long, I As Long
List1.Clear
Call EnumProcesses(ProcessIDs(1), 256, cbNeeded) '返回进程PID数组和进程数组大小
ProcessCount = cbNeeded / 4 '计算出进程数
For I = 1 To ProcessCount
hProcess = OpenProcess(&H400 Or &H10, False, ProcessIDs(I))
If hProcess <> 0 Then
ModuleName = Space(255) '为模块名分配空间，这很重要
'模块句柄指针为零默认获取进程名，无需枚举进程模块
lRet = GetModuleFileNameExA(hProcess, 0, ModuleName, 255)
List1.AddItem ProcessIDs(I) & Chr(9) & ModuleName '将进程PID和路径添加到列表框
End If
lRet = CloseHandle(hProcess) '关掉进程句柄
Next
End Sub
