I have recently studied how to convert video formats from mencoder. Rmvb conversion is required: 1. Copy drv43260.dll to the System32 folder of the system.2.

, problem solving.Note: I don't think it's a log problem, so this method doesn't even try.3, create the data directory, that is, in your zoo.cfg configuration file datadir The specified directory to create the myID file, and specify the ID, change the ID of your zoo.cfg file in server.1=localhost:2888:3888 1. Just write 1 on the myID head.Note: Found online a lot of people use this method to solve their own problems, but my myID file configuration

There are times when we need to run the software alone instead of repeating it for no reason.Let me give you an example: Can you choose to run the music playback software repeatedly?You have a right-click shortcut open in the registration form (REG), but if the softis simply meant to be repeated running instances presumably users see such a softThe expression must be very exaggerated and amusing.

I used php to develop a small module that checks whether a website is running normally. my idea is to construct an http request and check the status code returned by it. If it is 200, it proves that the website can be accessed normally. A function called curl

Many Zookeeper scenarios require that we embed Zookeeper as part of our distributed application system to provide distributed services. in this case, we need to start Zookeeper through a program. In this case, you can use the ZooKeeperServerMain class of ZookeeperAPI to start the Zookeeper service. #160; below
