As a result , as well as an exercise in cross - platform multi - tier architecture , you ll build the client on windows , using delphi or c builder the screenshots will be delphi , but you can perform the same steps using c builder , and i will list both delphi and c code in the source code listings 因此,我們將使用delphi或c + + builder構建windows上的客戶機(這里給出的屏幕快照將是delphi ,但可以使用c + + builder執行相同的步驟,在源代碼清單中我將同時列出delphi和c + +的代碼) ,同時也將此作為跨平臺多層架構中的一次練習。
