possible to operate on common LAN only after the maximum transmission unit is set to 1492. How to check whether the MTU of the gateway opens the dos window on the local machine and execute: ping-f-l 1472 192.168.0.1 where 192.168.0.1 is the gateway IP address and 1472 is the length of the packet. Note that the preceding parameter is "-l" (lower-case L), rather than "-1 ". If the packet can be pinged, it means that the packet does not need to be split and can be sent out through the gateway.

How to use code to set operations in IE and FF to change the Script or JavaScript status in IE, whether it is disabled or enabled. The following articles do not support other browsers. Currently, two solutions are available (IE is used as an example) First, use an automated tool to capture the process id of IE, capture the files, tools, and menu items of IE, click and capture them step by step, and then click and save them. Second, write code, modify existing resources that can be changed, and

The variance can be calculated by averaging the square sum of the difference between each data and the average. For example, given a set of numbers that represent the age of th
