Based on the official knowledge base, currently there is no “out of the box” way to control events visibility — no plugin setting,  plugin filter,  etc.  But with a bit of custom coding, you can get pretty close. 1. Hide event from month view if the use is not logged in. Ref: https://theeventscalendar.com/knowledgebase/k/making-a-members-only-calendar/ 1. create a event category: Agent Assign the event to the category. 2. add stylesheet, e.g. Custom CSS & JS plugin. .type-tribe_events.tribe-events-category-agent { display: none; } body.logged-in .type-tribe_events.tribe-events-category-agent { display: inline; } 2. disable popup tip window. ref: https://theeventscalendar.com/support/forums/topic/disabling-the-calendar-pop-up-views/ body .tribe-events-calendar .tribe-events-tooltip { visibility:hidden; } @media (max-width: 600px) { body .tribe-events-calendar .tribe-events-tooltip { visibility:hidden; } }

条件语句的作用是更改控制流，任何程序都离不开条件判断。但条件判断会增加程序的复杂度，过多的条件判断会导致循环复杂度（Cyclomatic Complexity）。 这种复杂度取决于3个因素： 分支变量数 分支数 条件嵌套深度 if else if else if else if switch case 1: ... case 2: ... end switch ...... end if end if end if end if 这种形状也叫 Arrow Anti Pattern。它不仅降低程序的可读性，难以扩展和重用，还会轻易地隐藏许多bug。是我们必须避免的代码。 设计模式注重于软件的重用性和扩展性，但大多数模式都可以用来降低循环复杂度。设计模式可以让不同参与者分担这些条件语句，每个参与者解决一部分问题，这样控制流程就更简单，从而降低他们的循环复杂性。 这里介绍一个用策略（Strategy）设计模式来降低循环复杂度的例子。 假设现在我们可以用 C# 写一个简单的计算器，代码如下： using System; public class Calculator { public double Calculate(double operand1, double operand2, char operater) { double result = 0.0; switch (operater) { case '+': result = operand1 + operand2; break; case '-': result = operand1 - operand2; break; case '*': result = operand1 * operand2; break; case '/': if (Math.Abs(operand2) > 0.0) { result = operand1 / operand2; } else { throw new ArithmeticException("分母为零。"); } break; default: throw new ArgumentException("未知运算符: " + operater); } return result; } public static void Main(String[] args) { args = new[] { "2", "*", "3" }; double operand1 = Double.Parse(args[0]); double operand2 = Double.Parse(args[2]); char operater = args[1][0]; double result = new Calculator().Calculate(operand1, operand2, operater); Console.WriteLine(operand1 + args[1] + operand2 + " = " + result); Console.ReadKey(); } } 现在用策略模式来重构这段代码： 模式角色： Strategy: IProcessor ConcreteStrategy: Adder, Subtractor, Multiplier, Divider Context: Calculator using System; using System.Collections.Generic; public interface IProcessor { double Process(double operand1, double operand2); } public class Adder : IProcessor { public double Process(double operand1, double operand2) { return operand1 + operand2; } } public class Subtractor : IProcessor { public double Process(double operand1, double operand2) { return operand1 - operand2; } } public class Multiplier : IProcessor { public double Process(double operand1, double operand2) { return operand1 * operand2; } } public class Divider : IProcessor { public double Process(double operand1, double operand2) { double…

Joining all column values into one string with concat function is a pain, especially for a table with large numbers of columns. This script concats all columns quickly. declare @sql varchar(max) SELECT @sql = ISNULL( @sql+ '' + '+'',''+', '') + 'convert(varchar(50), [' + c.name + '])' FROM sys.all_columns c join sys.tables t ON c.object_id = t.object_id WHERE t.name = 'herb' and c.name!='id' EXEC( 'SELECT ' + @sql + ' FROM herb') Result The script generates long string value of @sql as following: convert(varchar(50), [alias])+','+convert(varchar(50), [application])+','+convert(varchar(50), [attachment])+','+convert(varchar(50), [category])+','+convert(varchar(50), [caution])+','+convert(varchar(50), [chemical])+','+convert(varchar(50), [desc])+','+convert(varchar(50), [english])+','+convert(varchar(50), [enterdate])+','+convert(varchar(50), [extract])+','+convert(varchar(50), [form])+','+convert(varchar(50), [form1])+','+convert(varchar(50), [grow])+','+convert(varchar(50), [guijing])+','+convert(varchar(50), [image_all])+','+convert(varchar(50), [image_leaf])+','+convert(varchar(50), [image_root])+','+convert(varchar(50), [indication])+','+convert(varchar(50), [indication1])+','+convert(varchar(50), [locations])+','+convert(varchar(50), [medicalprop])+','+convert(varchar(50), [name])+','+convert(varchar(50), [notes])+','+convert(varchar(50), [origin])+','+convert(varchar(50), [pharmacology])+','+convert(varchar(50), [pinyin])+','+convert(varchar(50), [process])+','+convert(varchar(50), [source])+','+convert(varchar(50), [store])+','+convert(varchar(50), [url])+','+convert(varchar(50), [usage])

Content data on webpage: It's html code looks like this: Parsing data using regular expression with named group. Use foreach loop to avoid the order change on page. Do not use the text value from dom function/property, because the text value does not contain html tag, which gives you the mark on data.

Problem Clicked Revert button by mistake, and then make change on code, try to Commit /Push, got failed. Look at the Commit details, it looks like this: Error message "github failed to push to the remote repository. see the output window for more details". Fix Go to settings -> Emails, uncheck "Block command line pushes that expose my email" option. Successfully pushed.
