shutdown

问题 I am working on a binary file transfer program in which the client has to upload a file to server. For this case, I need to send the file name first and file content second. But this is not feasible for me. Lets see the code: // Client-side code to send file name void sendFileName( int sd, /*Socket Descriptor*/ char *fname) /*Array Containing the file name */ { int n , byteswritten=0 , written ; char buffer[1024]; strcpy(buffer , fname); n=strlen(buffer); while (byteswritten<n) { written

问题 I have a Minecraft bedrock edition server running on our shared pc. I would like to interface with it via python. However, one problem I have is that my brothers sometimes restart our pc, or Windows updates. I need to know how to detect that shutdown event and send the shutdown command to the server before restart.

问题 I write a local service application using C++ and I can't find the correct way of registering for a pre-shut-down notification (for OS later than Windows XP). I believe that SERVICE_CONTROL_PRESHUTDOWN notification has been added since Vista, but when you call SetServiceStatus do we need to specify: dwServiceStatus.dwControlsAccepted = SERVICE_ACCEPT_PRESHUTDOWN; or dwServiceStatus.dwControlsAccepted = SERVICE_ACCEPT_SHUTDOWN | SERVICE_ACCEPT_PRESHUTDOWN; 回答1: You cannot accept both a

问题 Is there any possible way to add swing into a shutdown hook (that is, display a popup upon the VM shutting down)? I realize that if I try to make a new JFrame, it will give me an error, as it tries to register a shutdown hook, which fails as the VM is already shutting down. I'm just wondering if there is in fact any way around this 回答1: You really shouldn't be doing this. From the Runtime.addShutdownHook specification: The Java virtual machine shuts down in response to two kinds of events:
