wrong javascript in jquery

good javascript in jquery

<div id="mylinks">

Javascript를 사용할 때 '튀지 않는' Javascript를 만드는 방법
* Javascript를 전혀 사용하지 않으면서 응용프로그램이나 기능을 구축해얒 한다. 실행 가능한 기능들을 채택하고 일반적인 HTML/CSS의 한계를 받아드린다.
* 원 markup을 건드리지 않는 범의 한에서 Javascript를 사용한다. 그리고, 되도록 Javascript를 별도의 파일로 분리하자. 개별적으로 인식이 가능하고, 관리할 수 있는 방법을 제시해야지 된다.

.NET으로 COM+ 객체를 만드는 예제.

.NET으로 COM+객체를 만들때는 먼저 Project Property에 Comvisible(true)로 설정이 되어 있어야지 된다. 그리고 assembly:Guid 속성에 component guid를 등록시켜야지만 com 객체를 만드는 가장 기초적인 설정이 끝이 난다. 이와같은 설정을 하면 작성된 dll이나 exe를 com+ 객체로 등록할 수 있다.

// Setting ComVisible to false makes the types in this assembly not visible 
// to COM components.  If you need to access a type in this assembly from 
// COM, set the ComVisible attribute to true on that type.
[assembly: ComVisible(true)]
// The following GUID is for the ID of the typelib if this project is exposed to COM
[assembly: Guid("3308202e-a355-4c3b-805d-b527d1ef5fa3")]

그러나, dll을 등록한다고해서 library안의 class들이 모두 com객체로 사용할 수 있는 것이 아니다. dll은 여러개의 com객체를 담을 수 있는 상자이고, 그 상자안에 채워야지 될 com객체들은 각각 작성되어야지 된다. com을 이용하는 것은 com 객체 뿐 아니라, com 객체를 구성하고 있는 interface역시 사용할 수 있어야지 되기 때문에, com으로 외부에서 노출될 모든 interface와 class들은 Guid Class Property를 갖고, 각 Guid 값을 가져야지 된다.

com으로 사용되기 위해서, class와 interface가 가져야지 될 속성은 각각 다른데, interface는 ComInterfaceType Property와 Guid를 가져야지 되며, class는 Com으로 제공될 ComSourceInterfaces, ClassInterface, Transaction, Guid, Com 객체 사용에서 Pool과 CreateTimeOut을 제한하는 ObjectPooling attribute를 가져야지 된다.

0010. CSSocketClient

Sample Codes 2010. 1. 5. 18:00

Client 소스는 좀더 간단하다. Server의 경우에는 Bind와 Listen의 절차를 거치고, Listen에서 BeginListen, EndListen으로
AsyncCallback을 통해야지 되지만, Client의 경우에는 간단히 Connect만으로 가능하고, 하나의 Client에서는 역시 하나의
연결정도만 신경을 쓰면 되기 때문에 더욱더 편한 개발이 가능하다.

솔찍한 생각으로 예제 소스이긴 하지만, UI단만 조금 붙여버리면 거의 일반 프로그램들과 큰 차이가 안보인다.
Socket의 Close시에 Shutdown으로 Socket을 정리하는 부분에 신경을 쓰면 될 것 같다.

0009. CSSocketServer

Sample Codes 2010. 1. 5. 17:56

Socket을 사용해서 TCP/IP 서버를 만들게 되면 개발에서 가장 신경쓰게 되는 것이 Multi-Thread 문제이다.
이부분에 대해서 .NET에서 내놓은 최고의 Solution은 IAsyncCallback interface를 이용해서 BeginXXX 와
EndXXX를 이용하는 방법이다. 이 방법은 WebService client, Stream, Socket 등 데이터를 읽고, 쓰는데에
시간이 소요가 되어 Multi-Thread를 구현해야지 되는 거의 모든 경우에서 사용이 가능하다.

예제 소스는 다음과 같다. IPV6를 사용하는 소스를 IPV4로만 변경시킨 예제이다.

0008. CSWindowsHook

Sample Codes 2010. 1. 5. 16:26

Windows Hooking의 경우에는 Windows message queue에 대한 이해가 좀 필요하다.
Windows는 Windows Message Queue를 통해서 각각의 Message를 전달하고, 그 Message에 따라 각기 다른 Action을 행한다.
WM_PAINT의 경우에는 화면을 그리라는 Message가 되고, WM_MOUSE의 경우에는 Mouse의 움직임에 따라 발생되는 Windows
Message이다.

Hooking은 이런 WIndows Message Queue에 Hook을 걸어서, 원래 처리되어야지 되는 함수가 아닌, 사용자 지정 Method에서
처리하게 하는 방법이다. 이것을 이용하면 Ctrl+Alt+Del의 기능도 막아버릴 수 있으며, 마우스를 움직여서 다른 동작을 하는 것도
막는 것이 가능하다. 또한 Mouse나 Keyboard의 모든 기록들을 저장할 수 있기 때문에 Windows에서 Cracking을 하는 경우에
왕왕 사용되는 방법이다.

먼저, WIN32 함수인 SetWindowsHookEx 함수를 DllImport시켜서 가지고 온다. 필요한 Native method의 선언은 다음과 같다.

internal delegate int HookProc(int nCode, IntPtr wParam, IntPtr lParam);
 
internal class NativeMethods

    /// Hooking WIN32 API
    /// dwThreadId가 0인 경우에는 전역 hook

    /// <param name="callback">Hooking을 한 이후에 받을 method의 주소값 delegate된 method를 넣어줄수 있다.

별다를 것이 없는 코드.
Visual Studio에서 Generate되는 code만을 간단히 이용하지만, Windows EventLog를 사용하는 법이 나온 부분만 체크해보면 될 것 같다.
또 하나가 있다면, ProjectInstaller 역시 살펴 볼 내용.

Windows Service를 등록하기 위해서는 InstallUtil을 이용해서 Service를 등록시켜야지 되는데 이때 등록할 ServiceName과 Service의
이름을 일치시켜주는 것이 필요하다.

private void InitializeComponent()

xml파일을 각 ElementNode별로 읽고, XmlDocument를 생성하고 저장하는 sample code
XmlDocument에 새로운 Element를 생성하는 것은 생성후에 XmlDocument에 넣는 것이 아니라, XmlDocument를 통해 객체를
생성하고, 생성된 객체에 값을 넣은 이후에 XmlDocument에 Append하는 과정을 거쳐야지 된다는 것을 기억하면 매우 쉬운 소스다.

0003. XmlSerialization

Sample Codes 2010. 1. 5. 13:15

.NET에서 Serialization은 객체를 저장하고, 객체를 다시 불러오는데 매우 유용하다. 그리고 네트워크로 Serialization된 객체를 전송하고,
다시 그 객체를 사용할 수 도 있는 .NET에서 핵심적인 기능중 하나이다.

XmlSerialization을 하기 위해 가장 유의할 점은 생성자는 input parameter가 없는 생성자만이 가능하다는 점을 항시 알아야지 된다.
input parameter가 있는 경우에는 Runtime시에 exception이 발생되게 된다.
