The logical coordinates are mapped to different display devices, and both x and Y are mapped, so that even if the device is different, x and Y change at the same time, so the shape of the drawing is not changed. Use GetDeviceCaps to set the

This article analyzes the maximum and time measurement of the C-language continuum vector, and shares it for everyone's reference. The specific method is as follows: #include #include #include #define SCALE 3000 int maxnum (int a, int b);

To query for a short period of time can be from v$sql or V$sqlarea if you want to query for a week or one months then it is possible to find in the V$sqlarea! The following is obtained through the historical Dba_hist_sqlstat, which is preserved by

Next, we create a stored procedure to collect and collect statistics on the files of these databases. For the period-over-period comparison, the normal situation is: Period-over-period comparison (current value of the indicator) Next, we create a

The classification of common routing information protocols (RIP): Dynamic and Static. Intranet Gateway Protocol (igp): rip igrp VPN ospf is-is external Gateway Protocol (egp): bgp4RIP is a distributed Distance Vector-based routing protocol, is the standard protocol of the Internet, its biggest advantage is simple. The RIP Protocol defines "distance" as the distance from a router to a directly connected network as 1. The distance from a vro to a non-directly connected network is defined as the di
