使用Delphi开发高效的数据库应用系统（实例源码），从测试dbexpress、bde/idapi和dbexpress开始，观察dbexpress的执行行为，dbexpress和bde/idapi的性能比较，访问大量数据的速度，调整dbexpress访问数据的方式，调整packetrecords特性值，改变dbexpress处理数据的行为，delphi 7之后的tsimpledataset，实例包中的源码将向您展示上述知识。 (Use Delphi to develop efficient database system (example source code) from test dbExpress, bde/idapi start and dbexpress, to observe dbexpress execution behavior, dbexpress the bde/idapi performance comparison speed access to large amounts of data, adjust dbexpress access data way, to adjust packetrecords characteristic values ​ ​ change behavior of dbexpress processing data source delphi 7 tsimpledataset, Examples will show you the above knowledge.)

winAPI实现的记事本，体积很小，有保存读取功能(WinAPI notepad)

Delphi连接MSSQL读取数据并横向打印内容，编程学习源码，很好的参考资料。(Delphi MSSQL read data connection and landscape printing content, programming learning source, a good reference.)

delphi 开发的bease64的演示文件， 非常好用(delphi development bease64 presentation file, very easy to use)

说明：  功能強大的繪圖軟體,可做到類似corel draw的功能.V1.5版架構較小,容易修改(FlexGraphics 1.5 full source)

A simple port scanner,enjoy :P

说明：  Delphi:五金材料行业Delphi进销存程序，源代码，我想把这做成一个自由软件，这是一个我以前自写的进销存源码，系统架构于Delphi6+Sql2000，程序写了几个大的功能模块，基本功能还是已完成，如退货等要迟点做。程序用了infopower , 1stclass ,mxoutbar,tb2k,flatstyle及几个收集或自写的VCL(不要也行的)，还有程序默认的数据库服务器是wwnt,你可以在data那里修改回来，重新编译就可以了。 (Delphi: Delphi metal materials industry Invoicing program, source code, I m trying to make a free software, which is written by one of my former self Invoicing source, system architecture in Delphi6+ Sql2000, wrote several large programs functional modules, or have completed the basic functions, such as the return of the point you want to do later. Procedures used infopower, 1stclass, mxoutbar, tb2k, flatstyle and a few from the collection or write VCL (do not have the line), as well as the program default database server is wwnt, you can modify the data back in there, you can recompile a.)
