Implementation of fix messages for fix 5.0 sp2 and fixt1.1 specificationNeeraj Kaushik
This document summarizes how to connect to a FIX 5.0 SP2 and FIXT 1.1 server and implement FIX messages using QuickFix/N, an open source .NET FIX engine. It demonstrates creating a FIX initiator client application that can send and receive messages like MarketDataRequest and the responses MarketDataSnapshot and MarketDataIncrementalRefresh. The key steps shown are configuring the initiator, creating an application class that implements the QuickFix interfaces, setting up the initiator, and implementing message handling callbacks. Code examples are provided.
This document discusses JavaScript events. It defines an event as something that occurs when a user or browser manipulates a web page, like loading the page, clicking a button, or resizing the window. Developers can use events to trigger JavaScript code that responds to these user actions. Common event types discussed include onclick, which occurs when a user clicks an element, onsubmit for form submission, onmouseover/out for mouse movement, and onchange for input field changes. Examples are provided to demonstrate how to attach event handlers to elements to run JavaScript code in response to events.
The Document Object Model (DOM) is a standard for representing and interacting with objects in HTML, XML and SVG documents. It defines the logical structure of documents and the way a document is accessed and manipulated. The DOM represents the document as nodes and objects, which can be manipulated programmatically by JavaScript to change the document structure, style and content. It allows dynamic access to and manipulation of page content that is useful for building interactive web applications. The DOM specification is developed by the W3C and provides a platform- and language-neutral interface that can be used across different web technologies.

ListBox와 Linq 쿼리를 이용한 간단한 데이터바인딩, 새창 띄우기, 이벤트 및 델리게이트를 통한 메인윈도우의 ListBox Refresh 적용 실습
직무타입(내근:Inner, 외근:OutSide)과 직무목록을 보여주는 두개의 ListBox 컨트롤을 사용해서 직무타입을 선택하면 Linq를 통해 해당 직무타입의 직무를 쿼리해서 하단의 ListBox에 보여주는 예제이다.
“직무추가” 버튼을 클릭하면 새창이 뜨고 직무를 입력 후 저장 버튼을 클릭하면 직무입력 화면이 사라지고 메인 윈도우 상단의 ListBox가 새창에서 입력한 직무타입으로 선택되면서 하단의 ListBox는 해당 직무타입의 직무목록으로 자동으로 Refresh 된다.
This document discusses JavaScript events. It defines an event as an action a script can respond to, such as clicks or keystrokes. Event handlers are functions assigned to events that run when the event occurs. Events follow a cycle of capturing, targeting, and bubbling. Common event types include mouse, keyboard, loading, selection, and other events. The document provides examples of using event handlers with buttons, images, and adding/removing event listeners.
The document discusses JavaScript events and event handling. It covers the different phases of events, how to define event handlers, the event object, and how to cancel bubbling and override default browser actions. It also provides examples of handling mouse and keyboard events, such as changing an element's style on mouseover and logging key events.
The document discusses the Document Object Model (DOM), which defines a standard for accessing and manipulating HTML and XML documents. It allows programming interfaces to dynamically access and update the content and structure of documents. The DOM represents the page as nodes and objects. It describes the DOM tree structure with parent-child relationships, and methods for accessing nodes by name, ID, tag name, or relative positioning. Examples are given for adding a new text node to the DOM tree. Advantages are robust APIs and easy data modification. Disadvantages include storing the entire document in memory.
This talk introduces and discusses a novel, mostly unpublished technique to successfully attack websites that are applied with state-of-the-art XSS protection. This attack labeled Mutation-XSS (mXSS) is capable of bypassing high-end filter systems by utilizing the browser and its unknown capabilities - every single f***** one of them. We analyzed the type and number of high-profile websites and applications that are affected by this kind of attack. Several live demos during the presentation will share these impressions and help understanding, what mXSS is, why mXSS is possible and why it is of importance for defenders as well as professional attackers to understand and examine mXSS even further. The talk wraps up several years of research on this field, shows the abhorrent findings, discusses the consequences and delivers a step-by-step guide on how to protect against this kind of mayhem - with a strong focus on feasibility and scalability.
Excel shortcut and function keys hindi notesSirajRock
The document discusses various features and functions of Microsoft Excel. It describes that an Excel file contains workbooks which have worksheets. By default, Excel has 3 worksheets but this can be increased. Each worksheet can have a maximum of 16,384 columns and over 1 million rows. Cells are referenced by their column and row address. Formulas in Excel use cell references. Excel contains various mathematical, statistical, text and logical functions to perform calculations on data. Date and time functions are also available to work with dates and times. Excel can also import and export data from databases and other file formats.

This document describes an implementation of backpropagation algorithm in C code to understand the backpropagation algorithm through programming. It also explains how it can be applied to a real-world case of handwritten digit recognition using TensorFlow code. The neural network code can be used to gain experience by adjusting values and observing their effects on the network.
To install Python and TensorFlow, download Python version 3.5.2 from the Python website and TensorFlow from the TensorFlow website. Python 3.5.2 must be installed before installing TensorFlow. Once Python is installed, add it to the system PATH and install pip. Then use pip to install various Python packages like iPython, PyQt5, Matplotlib, OpenCV, and Spyder for data science and machine learning.
This document discusses convolutional neural networks (CNNs) for image recognition. It explains key CNN components like convolutional layers, pooling layers, hyperparameters like kernel size and stride. It provides code in TensorFlow to recognize handwritten digits from the MNIST dataset using a CNN model with convolutional and pooling layers. The code trains the model on MNIST data and evaluates test accuracy.
The document discusses interfaces in COM. It explains that interfaces allow invoking functions of COM objects indirectly using virtual function techniques. It shows how to define a pure abstract interface class and have implementation classes inherit the interface. Clients can call interface methods without knowing the underlying implementation class. Later sections discuss adding multiple interfaces to a class, querying for interfaces, and how a client can load and use a COM server from a DLL.
This document discusses the COM (Component Object Model) architecture. It covers topics such as how COM uses the Windows Registry to associate components with their class identifiers (CLSIDs) and locations, how clients can load and interact with servers through functions like CoGetClassObject and CoCreateInstance, how servers implement functions like DllRegisterServer to register themselves, and how interfaces are defined using Interface Definition Language (IDL) and compiled using MIDL. It also compares the COM architecture to web services, noting differences in technologies used like IDL vs WSDL and the Windows Registry vs UDDI for discovery.
신경망의 층이 늘어났을 때 (즉 신경망이 깊어졌을 때), 학습의 어려움을 해소하기 위해 제시된 선행학습 관점에서 DBN과 AE를 소개합니다. 또한 다른 접근법으로 문제를 해소하여 뒤 늦게 심층 신경망으로 간주되고 있는 CNN을 소개합니다.
DBN에 사용된 RBM, AE는 GAN과 더블어 비교사학습 방법을 이끄는 삼두마차입니다. CNN은 영상학습 분야의 단연 절대강자입니다.
산포된 데이터를 정합하는 직선을 찾는 것으로 이해해도 무방합니다. 주어진 데이터를 이용해 기울기와 절편을 구하는 방법입니다.
먼저 행렬연산을 통해 구하는 방법을 설명합니다. 그리고 퍼셉트론에 사용된 것과 같은 방법을 다시 설명하므로 선택적으로 듣기 바랍니다.
설명된 예제에 대한 C 언어 코드를 제공합니다. Tensorlow 코드는 정합 과정을 시각화하여 보여줍니다.
퍼셉트론의 한계를 극복하는 방법입니다. 퍼셉트론은 나오자 마자 한계에 봉착했는데, 이를 해결하기 위해 구조적인 확장을 하게 됩니다. 그러나 정작 중요한 것은 이 확장된 구조에서의 학습 방법을 오랫 동안 찾지 못한 것입니다. 여기서 소개하는 신경망 학습방법은 신경망 학습방법의 거의 전부라고 할 수 있습니다.

PostQuitMessage 함수 때문에 “나죽네” 출력 후 프로그램 종료
그럼 검은색 윈도우는 어떻게 되나? 프로그램은 종료되었는데
LRESULT CALLBACK WndProc(HWND hWnd, UINT mesg, WPARAM wParam, LPARAM lParam)
{
switch(mesg)
{
case WM_DESTROY :
MessageBox(hWnd, "나죽네", "", MB_OK);
PostQuitMessage(0);
return FALSE;
}
return DefWindowProc(hWnd, mesg, wParam, lParam);
}
흰색 윈도우의 파괴버튼 눌렀을 때
자동으로 파괴될 것 같기도 하고… 잘 모르겠다
5. 5
검은 윈도우도 사라진다
하지만 “나죽어?” 대화상자는 안 나온다
그래서, 명시적으로 파괴하는 것이 좋다
BOOL DestroyWindow(HWND hWnd)
윈도우 파괴
LRESULT CALLBACK WndProc(HWND hWnd, UINT mesg, WPARAM wParam, LPARAM lParam)
{
switch(mesg)
{
case WM_DESTROY :
MessageBox(hWnd, "나죽네", "", MB_OK);
DestroyWindow(_hWnd2);
PostQuitMessage(0);
return FALSE;
}
return DefWindowProc(hWnd, mesg, wParam, lParam);
}
전역변수이기에 가능
검은 윈도우의 파괴에 대한 메시지 박스 문구
6. 6
윈도우간의 부모 자식 관계
검은색 윈도우를 흰색 윈도우의 자식 윈도우로 설정
윈도우간의 서열관계 형성
부모 윈도우를 황제라고 생각,
황제가 죽으면 신하들도 매장
내가 죽을 것 같으면 너부터 죽이고 나서 죽을래
프로그래머가 신경 쓰지 않아도 운영체제가 알아서 처리 해줌
8. 8
_hWnd2 = CreateWindow(
"WND2",
"WORLD",
WS_OVERLAPPEDWINDOW,
320, 0, 320, 240,
hWnd,NULL, hInstance, NULL
);
윈도우 초기 위치 및 크기
LRESULT CALLBACK WndProc2(HWND hWnd, UINT mesg, WPARAM wParam, LPARAM lParam)
{ switch(mesg)
{
case WM_DESTROY:
MessageBox(hWnd, "나죽어?", "", MB_OK);
PostQuitMessage(0);
return FALSE;
}
return DefWindowProc(hWnd, mesg, wParam, lParam);
}
자식 윈도우가 파괴될 때 프로그램까지 죽을 필요는 없으니까
자식 윈도우 프로시저의 PostQuitMessage 함수 호출은 생략
9. 9
LRESULT CALLBACK WndProc(HWND hWnd, UINT mesg, WPARAM wParam, LPARAM lParam)
{
switch(mesg)
{

MessageBox(hWnd, "나죽네", "", MB_OK);
DestroyWindow(_hWnd2);
PostQuitMessage(0);
return FALSE;
}
return DefWindowProc(hWnd, mesg, wParam, lParam);
}
자식 윈도우의 WM_DESTROY 먼저 처리
그래서 화면에 메시지 박스 나오는 순서는
진짜 자동으로 자식 윈도우 파괴해 주는구나
10. 10
자식 윈도우는
자식 윈도우는 부모 윈도우의 필요에 의해 생성하는 것이므로
부모 윈도우 프로시저에서 사용할 터
부모 윈도우 프로시저에서 생성한다
그런데 프로시저 어디에 코드를 넣나 ?
11. 11
부모 윈도우가 생성 될 때
어디서 ?
무슨 이벤트 일 때 생성 ?
부모 윈도우가 생성 될 때 발생하는 메시지
WM_CREATE
응애응애~

}
}
지역변수로 선언
부모 윈도우 프로시저니까
부모 윈도우 핸들
여기서 에러, 원래 WinMain 파라미터
hWnd 윈도우가 만들어 질 때
발생하는 이벤트
14. 14
부모 윈도우 프로시저에 다음 코드를 넣고 테스트
WndProc(…)
{
switch(mesg)
{
case WM_CREATE:
hWnd2 = CreateWindow(…, _hInstance, …);
break;
case WM_LBUTTONDOWN:
SetWindowText(hWnd2, "Black");
break;
…
}
}
자식 윈도우 타이틀이 Black 으로 바뀌지 않는다
왜 그럴까 ?
15. 15
WndProc 도
이벤트가 발생할 때 마다 호출되는 함수
WM_CREATE로 호출되었을 때 선언된 지역변수는
WM_LBUTTONDOWN로 호출될 때 다시 할당된다
HWND hWnd2
LRESULT CALLBACK WndProc(HWND hWnd, UINT mesg, WPARAM wParam, LPARAM lParam)
{
static HWND hWnd2;
switch(mesg)
{
case WM_CREATE:
hWnd2 = CreateWindow(…)
}
…
}
프로그램 수행 중에
메모리가 유지되도록
얘도 그냥 함수래
16. 16
윈도우 두 개 이상 생성할 때
상황에 맞게 부모-자식 관계 생성
자식 윈도우 생성은 부모 윈도우
프로시저의
WM_CREATE 메시지에서 처리
정리하면
