Delphi:Delphi环境下基于idtcpserver断开与连接客户端，当客户端主动与服务端断开时,idtcpserver事件Disconnect能够接到消息，当客户端主动与服务端连接时,idtcpserver事件Connect能够接到消息。但是存在问题：当服务端断开客户端连接数,IdTCPClient事件Disconnected接不到到消息，只有客户端主动与服务端断开时IdTCPClient事件Disconnected才接到消息，烦请高人们支招。 　　实例中还涉及到idtcpserver最大连接数在程序中如何控制的解决方法。 (Delphi: Delphi environment based idtcpserver disconnect the client when the client is disconnected from the server-side initiative, idtcpserver event Disconnect able to receive the message, when the client and server to connect initiative, idtcpserver Connect event messages can be received . But there is a problem: When the server is disconnected client connections, IdTCPClient event Disconnected not receive the message, only the client and server is disconnected when the initiative IdTCPClient event Disconnected before receiving the news, I beg you high people Weapon. Example also involves solutions idtcpserver maximum number of connections in the program how to control.)

Delphi附加数据库并保存连接参数信息，编程学习源码，很好的参考资料。(Delphi additional database connection parameters and save the information, learn programming source code, a good reference.)

EXIF信息代表的是可交换图像文件信息。当你储存JPEG或者TIFF格式的照片时，这张照片的所有信息都储存在EXIF信息中。几乎所有的相机厂商都支持拍摄的照片输出EXIF信息。(EXIF information represents exchangeable image file information. When you save a photo in JPEG or TIFF format, all information of the photo is stored in EXIF information. Almost all camera manufacturers support the output of EXIF information for photos taken.)

说明：  Delphi屏幕放大镜，编程学习源码，很好的参考资料。(Delphi screen magnifier, programmed learning source, a good reference.)

Pascal精要 第一章 Pascal历史回顾 Delphi中使用的面向对象pascal编程语言并不是borland公司1995年发布可视化开发环境Delphi时才有的，它只是已有borland pascal产品的简单扩展。 Borland没有发明pascal，但它推广并扩展了pascal。 (Essentials of Pascal Chapter Pascal History Delphi used in object-oriented programming language pascal is not borland released in 1995, when Delphi visual development environment there, it' s just been a simple extension of the product borland pascal. Borland did not invent the pascal, but it is to promote and extend the pascal.)
