问题 I would like to know if there is any way of running an operation (like, calling a batch file) before a service is started using services.msc? I want my batch file to run before the service (tomcat installed as service) is actually started, when the user manually clicks 'Start' in Services. I don't know if this is possible or not. Thank you for your help in advance! 回答1: The answer to your question is NO , unless you want to modify Apache's procrun (which is written in C language). Depending

问题 We have a .net c# service that when tured on is chewing up more and more memory. It has one 'Service' derived class that basically creates other objects that encapsulate individual functionality that the service is meant to support. Im thinking that maybe I am creating an object and its not getting garbage collected due to a programming error. Anyone know the best way to find out what is going on without setting break points? 回答1: You can use memory profilers like memprofiler, ants profiler,

问题 We are developing C++ apps (lots of MFC) with Visual Studio 2005 on Windows. From time to time it happens that our nightly builds and/or unit tests hang because some part of some app or helper tool opens a message box in a corner case that is hit by the build. Since the automated stuff is run (by a Windows Service) without any desktop session attached, obviously no-one can confirm - or even read - the GUI messages. Is there any way to have Windows prevent apps from opening dialogs? Or maybe a

问题 I've a requirement in which i need to send 10000+ mails on a quarterly basis .

问题 I have an eBay account. To make updating my products easily, I created a windows service in C#. It waits (by FileSystemWatcher ) for an xml file and once a file is appeared, a service reads it and sends requests to eBay server through their API. A file might hold about 1000-3000 rows. Previously I used to create 12 threads to make it faster. I don't know why I chose 12 threads, I thought that was enough amount: not too much and not too little. So here is a method how I looked like before (bit

问题 I am writing a simple FTP service using TcpListener and would like to find out what hostname (domain with multiple subdomains) the incoming call is using. Is this possible? //Barebone TCPListener example System.Net.Sockets.TcpListener listener; listener = new TcpListener(IPAddress.Any, 21) listener.Start(); TcpClient client = listener.AcceptTcpClient(); //Great, incoming... what domain are they using to call my service? //This only gives me the local and remote IP.. //IPEndPoint LocalEndPoint
