继续昨天的有关任务管理器的问题！

1、我现在用EnumProcess()、EnumProcessModules()和GetModuleBaseName（）这几个函数来获得进程名称，出现问题：pid为0和8的两个进程得不到HMODULE(值为0)。怎样能得到该进程名称？

2、用如下方法判断进程是否是窗口出现偏差
if (!m_bVisible || (GetWindowLong(hwnd,GWL_STYLE) & WS_VISIBLE)) {
DWORD pidwin;
GetWindowThreadProcessId(hwnd, &pidwin);
if (pidwin==m_pid)
return TRUE;
有时候得不到所有的应用程序。
然后用GetWindowText()获得不了explorer应用程序的窗口名称。为什么？

3、用如下方法结束explorer进程会弹出关机画面，为什么？
//////////////////
// Kill a process cleanly: Close main windows and wait.
// bZap=TRUE to force kill.
//
BOOL CEnumKillProcess::KillProcess(DWORD pid, BOOL bZap)
{
CMainWindowIterator itw(pid);
for (HWND hwnd=itw.First(); hwnd; hwnd=itw.Next()) {
DWORD bOKToKill = FALSE;
SendMessageTimeout(hwnd, WM_QUERYENDSESSION, 0, 0,
SMTO_ABORTIFHUNG|SMTO_NOTIMEOUTIFNOTHUNG, 100, &bOKToKill);
if (!bOKToKill)
return FALSE; // window doesn't want to die: abort
PostMessage(hwnd, WM_CLOSE, 0, 0);
}

// I've closed the main windows; now wait for process to die.
BOOL bKilled = TRUE;
HANDLE hp=OpenProcess(SYNCHRONIZE|PROCESS_TERMINATE,FALSE,pid);
if (hp) {
if (WaitForSingleObject(hp, 5000) != WAIT_OBJECT_0) {
if (bZap) { // didn't die: force kill it if zap requested
TerminateProcess(hp,0);
} else {
bKilled = FALSE;
}
}
CloseHandle(hp);
}else
bKilled = FALSE;

return bKilled;
}
