-click the connection to open a simulator. We can also select a simulator in the shortcut menu bar during debugging. When we run the debugging program, the system will determine whether the simulator has been run. If no simulator is selected, enable the simulator. When debugging, the system will automatically deploy the program to our mobile phone or simulator. If you need a simulator to connect to the

can enter 127.0.0.1. Here we will test it on the local machine. Enough. Configure it. Here we need two places: 1. Find The apache2/conf directory and open httpd. conf, and then add loadmodule php5_module D:/PHP/php5apache2 after loadmodule. DLL, and add phpinidir "D:/PHP" to the interface. Note that the directory here is your directory, which means that the previous one loads php as a module, there is also the PHP configuration file under D:/PHP, which is obvious. 2. Locate addtype and add "add

Tags: vc c Language Data Structure I recently read "Data Structure" and want to write an algorithm in C language. I thought of using vc6.0. During my undergraduate course, I was very proud of the C language course.A helloworld cannot be written. It seems that both the language and IDE need to be met frequently. Otherwise, they will be unfamiliar and gossip is rare. We will use vc6.0 to createA helloworld program. 1 open vc6.0, file -- New 2
