connection

问题 I have the following code: ignore_user_abort(true); while(!connection_aborted()) { // do stuff } and according to the PHP documentation, this should run until the connection is closed, but for some reason, it doesn't, instead it keeps running until the script times out. I've looked around online and some recommended adding echo chr(0); flush(); into the loop, but that doesn't seem to do anything either. Even worse, if I just leave it as while(true) { // do stuff } PHP still continues to run

问题 I am trying to write a lot of data to MongoDB, in a Java loop. I am getting errors based on the number of connections open. My theory is that since MongoDB is not transactional, lots of connections can be opened simultaneously. However the Java code is also able to loop very fast, after a certain time the number of loop iterations starts overtaking the number of available connections and Mongo hits a wall. My code looks like this. I've seen it recommended to not do m.close() but then you just

问题 I'm still working on the same problem mention here. It seems to work fine especially after creating an AbstractModel class shown below: public abstract class AbstractModel { protected static Connection myConnection = SingletonConnection.instance().establishConnection(); protected static Statement stmt; protected static ResultSet rs; protected boolean loginCheck; // if userId and userLoginHistoryId are valid - true, else false protected boolean userLoggedIn; // if user is already logged in -

问题 I'm trying do download the MATLAB Raspberry Pi Support Package, but can't finish it due to an error occuring every time. I can go through every step until I put the sd card back to my Raspberry Pi and use an ethernet cable to connect the Pi with my PC.

Information about my PC: Windows 7, i7 processor, 64 bit, 8 GB RAM MATLAB R2014a Raspberry Pi

问题 I am tring to connect a remote server via openvpn using C#. I am able to connect it successfully. but disconneecting seems to not work properly.

I checked my "route print" and yes Tap is coming ahead of internet and hence couldn't access net. I connect using : openvpn --config client.ovpn --ca certificate.cer --auth-user-pass user.txt My disconnecting
