在98下写了个服务程序，把它放到注册表的RunServices键下，但是我注销后，程序起不了，原来注销后启动的是Run下程序，怎样只启动一个程序

只写在run 底下就已经够了
如果非要都写就加个锁
BOOL CYourApp::InitInstance()
{
if(FirstInstance())
{
return FALSE;
}
..............
}
BOOL CYourApp::FirstInstance()
{
BOOL bFound = FALSE;
// Try to create a mutex with the app's name
HANDLE hMutexOneInstance = ::CreateMutex(NULL,TRUE,_T(AfxGetAppName()));
// Already there...means that we are already running an instance
if(::GetLastError() == ERROR_ALREADY_EXISTS)
bFound = TRUE;
// Release the mutex
if(hMutexOneInstance)
::ReleaseMutex(hMutexOneInstance);
return(bFound);
}
