Activitymanager service instance, XE7 does not provide a default function, we imitate write a, this function in the back of the program to the foreground when the need to use: 1234567 function sharedactivitymanager: jactivitymanager; var aservice: jobject; beginaservice := sharedactivitycontext. Getsystemservice (tjcontext. Javaclass. Activity_service Result : = tjactivitymanager. Wrap((aservice as ilocalobject). Getobjectid); end; Now

Entry level Switches The application of entry-level switches is focused on small workgroups of 8 to 16 ports, which are suitable for low prices, where there is little need for expansion and management. They are often used instead of hubs to provide higher bandwidth than hubs and provide a more reliable connection. Instead of buying entry-level switches, people o

management function can monitor the traffic of each port, set the rate of each port, and turn off/open the port connection. By monitoring the switch ports, it is easy to distinguish the traffic of the network and to define the network fault quickly, and improve the manageability of the network. Port Aggregation This is a packaging technology that is a point-to-point link where both ends of the link can be switches,

Copy @ from http://www.zhangxinxu.comFour, must remember the stacking guidelinesThe following two are the golden rules for cascading fields. The overlay relationship follows the following 2 guidelines when an element is stacked: who is big on: when there is an obvious cascade level indicator, such as the recognition of the Z-INDX value, in the same cascading context, the cascade horizontal value of

The port of the core switch is mainly a fiber type, but the price of the switch fibre port is very expensive and requires special attention from the user, while the fibre port of the switch is not stacked and can only be used for cascading purposes. Analysis of the switch fiber port Cascade connection mode and basic types, welcome to add message. Cascading can use either a normal port or a special mdi-ii p

About CSS cascading contexts and cascading style issues Recently in the project encountered a let me want to die of the problem, I gave the project picture set a fade effect, a few opacity changes, but when I have a positioning element on it, the end of the animation, the positioning element is obscured, baffled, Google Day, only know is the cascade context, Stacking order to get ghosts, so here to

Tiered switches typically have two stacking styles: Star stacking and daisy-chained stacking. Daisy chain Stacking is a cascade structure based on cascading technology, there is no special requirements on the hardware of the switch, through relatively high speed port connection and software support, the final implementation of a multiple-switch cascade structure, through the loop, can achieve a certain de

Cascade Extension The Cascade extension mode is the most conventional and direct extension, and some of the older networks use hubs as cascaded devices. Because the hubs were already quite expensive, most enterprises could not choose a switch as a cascade device. That's because most team users are connected to a hub from a port level on the hub. In this way, the access ability is greatly improved, but due to some interference and human factors, so that the overall performance is very low, only

CSS (cascading style sheets) is used to specify the rendering of HTML documents. Everything has a sequence, all things have a seniority. Under normal circumstances, there is no difference, that is, the so-called equality of sentient beings. However, when conflicts occur, it is clear that it is impossible to do exactly the same, sequencing, identity differences appear. Cascading is the process by which a bro

Cascading Style Sheets (full name: Cascading style Sheets) 1. Introduce the standard CSS box model. What's different about the box model of the low version ie. 1.1 Category: IE box model and standard box model 1.2 Box Model: content, padding, border, margin 1.3 Differences In the box model: the width of the width=content of the element IE Box Model: the Width=content+padding+border of elements For example

, you can use multiple twisted pair wires to cascade two vswitches to increase the cascade bandwidth. Cascading also fails to reach a stack to increase the connection distance. For example, if a computer is far away from a vswitch and exceeds the maximum distance of 100 meters from a single twisted pair wire, a switch can be placed in the middle to connect the computer to the vswitch. The stacking cable is only a few meters at most, so you should cons

switch, and strike a balance between speed and anti-jamming. If the working environment is worse, electromagnetic interference is strong, this should choose the store and forward switch. If the working environment principle launch station and other strong radiation source, then can choose Cut-through switch completely. If you cannot accurately identify the working environment, and the speed requirements are not very harsh, you can choose fragment free. Some advanced

Stacking order and cascading context are two concepts, but they have an inseparable relationship, stacking order is very simple ^_^, serious thinking can be, and the stack context is insignificant, I just need to move the red line you understand, all said, is too simple. The first paragraph is difficult to understand, mainly with this article, only to resolve the displacement. Talk less, see the sword. In consideration of the possibility that two ele

For the connection between the switches, there should be more familiar two kinds: first, is stacked, two, is cascaded. The cascading approach is relatively easy to create bottlenecks between the switches, while stacking technology can increase the backplane rate, can eliminate the bottleneck of the connection between the swit
