Learn to build applications with Jakarta Struts, the most popular JSP development framework. Struts Kick Start is a "hands-on" book filled with sample applications and code snippets you can reuse, and in-depth coverage of new features in Struts 1.1. If you are looking for a practical book that "shows you how to do it", then Struts Kick Start is for you. Plus, it s the first Struts book with detailed examples of the major Struts tags
This application note describes the three methods that can be used to
program the Flash code memory of the 89C51Rx+/Rx2/66x families
of microcontrollers. It discusses in detail the operation of the
In-System Programming (ISP) capability which allows these
microcontrollers to be programmed while mounted in the end product.
These microcontrollers also have an In-Application Programming
(IAP) capability which allows them to be programmed under firmware
control of the embedded application. This capability is also described

FIBPlus is a component suite intended for work with InterBase. It is direct, fast and flexible InterBase connectivity for Delphi, C++ Builder, Ada and Kylix. FIBPlus supports Delphi 5-7, Delphi 2005, Delphi 2006, Delphi 2007, C++ Builder 5-6, C++ Builder 2006, C++ Builder 2007, Kylix 3, gnat-3.15p, gnat2006 GPL, and all versions of InterBase 4.x-7.x, InterBase 2007 and Firebird 1.x-2.x.
Using FIBPlus in your applications you do not need to install any additional software except for InterBase Client Software. FIBPlus supports all special InterBase features such as array-fields, event alerters, BLOB-fields, etc.
FIBPlus is a native component set and its evaluation versions are distributed partially in sources.
Registering FIBPlus you get full sources of components and technical support
procedure senddata
var
i:integer commflg : Boolean
begin
commflg:=true
for i:=1 to 8 do
begin
if not fcomm comml writecommdata(sendbutter,i) then
begin
Commflg=false
break
end
end
end
(4) 接收數據
在編寫基于串口的計算機工業測控時，通常需要由下位機向PC機發送數據以使PC機了解系統的測試數據或下位機的運行狀態，并進而控制下位機的行為。利用Spcomm串口控件接收下位機發送的數據信息的示例代碼如下：
//事件驅動方式接收數據程序
procedure TForm1.CommlReceiveData(Sender:Tobject Buffer:Pointer bufferLength:Word)
var
receivedata:array of byte
begin
sleep(100) //等待100ms，保證接收到所有數據
move(buffef ,receivedata,bufferlength)
//將接收緩存區中的數據轉移到數組中
……
end
(5) 關閉串口
在系統開發中，應注意在不使用串口時應及時關閉串口，釋放系統資源，否則可能會影響系統的其它應用。關閉串口的代碼如下：
procedure TForm1.FormClose ( Sender TObj ect:var Action:TCIoseAction )
begin
comml.StopComm
end
