PPC中检查某程序是否运行

第一种:
HANDLE hMutex=::CreateMutexW(NULL,true,L"程序名");
DWORD dwError=GetLastError();
if(dwError==ERROR_ALREADY_EXISTS)
{
  ::AfxMessageBox(L"The program is running!");
  return ;
}
::ReleaseMutex(hMutex);

第二种:
HWND hWmp=::FindWindowW(L"Dialog",L"程序窗口名");
if(hWmp)
{
   ::AfxMessageBox(L"The program is running!");
  return FALSE;
}

第三种:
PROCESSENTRY32   lppe;
memset(&lppe,0,sizeof(PROCESSENTRY32));
HANDLE handle=CreateToolhelp32Snapshot(TH32CS_SNAPALL,0);
lppe.dwSize=sizeof(PROCESSENTRY32);
::Process32First(handle,&lppe);
do
{
  HANDLE hh=::OpenProcess(PROCESS_ALL_ACCESS,FALSE,lppe.th32ProcessID);
  CString temp(lppe.szExeFile);
  if(temp.Find(L"程序名")>=0)
  {
   ::AfxMessageBox(L"The program is running!");
   ::TerminateProcess(hh,0xffffffff);
   ::CloseHandle(hh);
    break;
  }
  ::CloseHandle(handle);

}while(Process32Next(handle,&lppe));
::CloseHandle(handle);

以上三种方法,只能检查其它程序,而不能检查自身是否正在运行,因为windows mobile 系统的运行机制和PC机上的windows XP是不太一样的.
