Assuming that the local virtual machine IP is 192.168.23.128, if you want to use the domain name www.test01.com to access the virtual Web server, you only need to configure the following: In Windows, edit the C:\Windows\System32\drivers\etc\hosts file and add the following: # nginxTest192.168.23.128 www.test01.com# End nginxTest Linux, edit the/etc/hosts file and add the following: # nginxTest192.168.23.128 www.test01.com# End nginxTest The above describes the Nginx series (

Width property to 200, The value of the HorizontalScrollBarVisibility property and the Verticalscrollbarvisibility property is auto.Place a TextBlock text block inside the ScrollViewer control and add some content text in it for demonstration purposes, set the Height property of this text block and the value of the Width property to 300, This causes the size of the text block to exceed the width and height set by the ScrollViewer control, so the scrollbar of the ScrollViewer control is automati

DataGrid object does not have a Name property, so there is markup Extensions. This is so handy when we want to locate a control with no Name attribute, just to extend a name.9) Now our example TextBlock and TextBox is not in pairs, in order to achieve a more friendly interface generally need to appear in pairs, and to be on the same level, can not wrap, in WPF can not use absolute positioning, how should be implemented? Very simple, use the StackPanel panel. The modified code is as follows: 10)

One or three ways of defining:(1) var arr=array (x); ----UPPERCASEArr[k]= "a";Note: x is an array length, usually not written in weakly typed languages; K is the index value, counting from 0 ; A is value.(2) var attr=["A", "B"];(3) var attr=array ("A", "B"); or var attr= new Array ("A", "B"); Generally does not add new.Var x=attr.length; Represents the array length.Arr.push ("D"); will join the array in arr.Common first and second; pay attention to the way of writingSecond, iterate over the arra

x, Y is not changedNow that we have some understanding of the basic syntax of lambda expressions in our team, here are a few examples.First, this example shows how to pass parameters to a lambda expression:#include using namespace Std;int main (){int n = [] (int x, int y) {return x + y;} (5, 4);cout }Operation Result: 9As we can see through this example, the arguments are passed in by the ' () ' after the function body.The next example shows that you can use a lambda expression like a function

Netty PreliminaryWhy Choose Netty?Compared to NIO, to achieve a communication is much simpler, performance is very good. Distributed message middleware, Storm, and dubble all use Netty as the underlying communication.Netty5.0 requires more than jdk1.6.Http://netty.ioCreate two NIO thread groups, one event handler, one network read and write communicationCreate a serverbootstrap, configure the Netty parameter;Create the actual processing of the Channelinitializer, to initialize the preparation wo

The right area button and the entire title use Sortingorder+2.Particle settingsIn the ParticleSystem , find render to change its sortingorder to 1:UI SettingsThe variables in Ugui are SortingOrder defined in the canvas, so you need to be the class or its subclasses to implement the settings. You need to add a canvas for Button1 and title here. Because the canvas will also be accompanied by changes to its su

Basic method: Use a closure to return a function. 2. Tamper-proof objectsOnce the object is defined as tamper-proof, it cannot be undone. 1. Non-expandable objects var person={name: "ABC"};object.preventextensions (person); You cannot add new properties and methods to a person object after calling object.preventextensions(person), but you can modify and delete existing members. Use Object.isextensible () to determine whether an object can be extended. 2. Sealed obj
