C# Form 裡面使用 Timer

/*

之前使用 System.Timers; 但是在關掉視窗的時候好像怪怪的,不知到還需要都做什麼動作才可以。改用 System.Windows.Forms.Timer 就好多了,果然是為了 Form customized 的 Timer ...

*/

using System.Windows.Forms;

 

// 宣告 Timer

System.Windows.Forms.Timer aTimer;

 

// new 給他一個實體

aTimer = new System.Windows.Forms.Timer();

 

// 在接收 event 的 List 上加入你的函式

aTimer.Tick += new EventHandler(TimerEventProcessor);

 

// 設定 Timer 觸發的間隔

aTimer.Interval = 5 * 1000;  // 5 秒  = 5000 毫秒

 

// 開始計時

aTimer.Start();  // 停掉 Timer 請用 Stop()

 

// 你的函式,把你在 Timer 每次發生Event 的時候想做的事寫在裡面

private void TimerEventProcessor(object myObject, EventArgs myEventArgs){

    // do what you want when time out
    // 想做的事

}

Setting MySQL to Use UTF-8 on MAMP (MySQL 5.5.9, or 5+)

I wanted to setup MySQL to use utf-8 on the MAMP installation on my Mac. I tried the instructions from this article: http://cameronyule.com/2008/07/configuring-mysql-to-use-utf-8/ However, I kept getting error messages that are similar to this one [ERROR] /Applications/MAMP/Library/bin/mysqld: unknown variable 'default-collation=utf8_general_ci' I did some search and realized that several variables are deprecated. Reference: http://dev.mysql.com/doc/refman/5.1/en/server-options.html Therefore, I added the following lines into /Applications/MAMP/conf/my.cnf [mysql] character-set-server=utf8 [client] character-set-server=utf8 [mysqld] character-set-server=utf8 collation-server=utf8_general_ci init-connect='SET NAMES utf8' I restarted the server and mysql run successfully with relevant variables being set correctly. In the "Variables" tab under phpMyAdmin interface (ex. http://localhost:8888/MAMP/?language=English) character set c...

ngrok, a service to help you get a public URL for your local webserver

If you are looking for options to test your web app hosted on your own machine (e.g., laptop) remotely with someone, I recommend using a service called ngrok. https://ngrok.com/ It has many usages, but in the context of testing an app hosted on your own machine, the most important part is giving you a public URL that will redirect all the requests to your local webserver (e.g., Apache, Nginx, or whatever server you are running). You can give this URL to a testing participant without the need to host the app on a remote server. For instance, if you are testing your app using a sever on your machine, typically you can access your app in a URL like:  http://localhost:3000/?study=11 Using ngrok, you will have a dynamically generated URL like the following: https://3ebe3c019867.ngrok.io/ The service will redirect requests to https://3ebe3c019867.ngrok.io to http://localhost:3000 You can then share the following link with your testing participant for the participant to use your app. http...
