Collection, List, ArrayList....

Born in Pain — Fri, 30 Jan 2009 16:24:20 +0900

1. Arraylist 클래스

- 배열의 크기를 자유 자재로 변화시킬수 있다

- 서로 다른 타입의 원소들을 배열에 넣을수 있다.

ArrayList al = new ArrayList();
al.Add(100);
al.Add("이건 문자열");

foreach (object o in al)
{
Debug.Print(o.ToString());
}

==결과 ==

100
이건 문자열

그러나 중복된 데이터가 대한 Add 될수 있다. 이게 장점이 될수도 단점이 될수도 ..

즉

al.Add(100);

al.Add("이건 문자열");

al.Add(100); <- 또 추가된다는..

object 를 Add 한후에 나중에 검색할때는 foreach와 if 를 사용해서 찾아와야 한다는..

2. Stack 클래스

스택이라는 데이터 구조의 컬렉션은 나중에 들어온 데이터가 먼저 나오는 구조를 말한다.

Stack mStack = new Stack();

mStack.Push(100);

mStack.Push(("이건 문자열");

foreach(object o in mStack)

{

Debug.Print(o.ToString());

}

==결과 ==

스택 테스트
이건 문자열
100

3. Queue 클래스

Stack 과 달리 먼저 넣은 데이터가 먼저 나오는 구조를 말한다 ..

            Queue mQ = new Queue();
            mQ.Enqueue("큐 테스트");
            mQ.Enqueue(100);
            mQ.Enqueue("이건 문자열");

            foreach (object o in mQ)
            {
                Debug.Print(o.ToString());
            }

=== 결과 ==

큐 테스트
100
이건 문자열

4. SortedList 클래스

SortedList 는 앞에 클래스와 IDictionary 인터페이스를 구현하는데 , 가장 큰 특징은 키와 값을 이용한다는 것이다.

쉽게 이야기 해서 키와 값을 Add하는데 키 값으로 알아서 Sort 가 된다는 것이다..

            SortedList sl = new SortedList();
            sl.Add("하나", "가");
            sl.Add("둘", "나");
            sl.Add("셋", "다");

           for (int i = 0; i < sl.Count; i++)
            {
                string result = string.Format("GetKey[{0}] GetByIndex[{1}]", sl.GetKey(i), sl.GetByIndex(i));
                Debug.Print(result);
            }

== 결과 ==

GetKey[둘] GetByIndex[나]
GetKey[셋] GetByIndex[다]
GetKey[하나] GetByIndex[가]

5. HashTable 클래스

위에 설명한 클래스 들은 데이터를 찾고자 할때 데이터를 인덱스를 증가시켜 가면서 찾아야 하는데 반해

HashTable 클래스는 키와 값을 Add 하여 보다 손쉽게 찾을때 사용한다.

단 입력된 키는 중복되면 안된다..

Hashtable htTest = new Hashtable();

            htTest.Add("하나", "가");
            htTest.Add("둘", "나");
            htTest.Add("셋", "다");

            foreach (object o in htTest)
            {
                Debug.Print(o.ToString());
            }

string result = (string)htTest["키:하나"];

Debug.Print("result : " + result);

HashTable은 키를 가지고 정렬을 하지 않는것으로 SortedList 와 차이를 볼수 있으며 키들을 서로 다른 타입으로 정의해서 사용할수 있다.

Playing AVI Files using DirectX 9 with C# and .NET

Born in Pain — Fri, 26 Sep 2008 14:31:30 +0900

Figure 1 - Kangaroo Hopping Movie

Introduction

Just got back from a three week trip to Australia and all I can say is, "Give me a home among the gum trees." (Australian programmers will get what I'm saying here.). Most people know what a kangaroo looks like, but most haven't seen one up close. Needless to say, they are strange creatures if you are coming from the New York City. Unfortunately, the AVI kangaroo video taken by the digital camera was too large to upload to the site due to the size of the file. In any case, some of you are probably asking yourselves, "Kangaroos or not, how exactly do I play an AVI file in .NET?". This article will show you how by demonstrating the implementation of a WinForm Video Player.

The Player

The Video Player takes advantage of the DirectX AudioVideoPlayback library. This library mindlessly allows you to play videos inside a Video object. The methods of the Video class are very straight forward (e.g. Play, Stop, Pause) and you simply construct the video object with the name of the file (e.g. "roo.avi"). The tables below illustrate some important methods and properties of the Video class.

Method	Description
Open(string filename)	Opens an avi file with the passed parameter path name
Play	Plays the video
Stop	Stops the video
Pause	Pauses the video
SeekCurrentPosition(double time, SeekPositionFlags)	Moves to a particular time position in the avi file relative to the SeekPositionFlag. Time is in 1 x 10^-7 seconds (or 0.1 microseconds)
StopWhenReady	Waits for the video object to be ready for stopping, and stops the video

Property	Type	Description
Owner	System.Windows.Forms.Control	Sets The Window Forms Control that contains the video.
Fullscreen	bool	Sets whether or not the video is shown fullscreen
Size	Size	Sets the size of the video
Duration	double	Gets the time (in seconds) of the full video
CurrentPosition	double	Sets the position of the video
Audio	Microsoft.DirectX.AudioVideoPlayback.Audio	Audio object allows you to control things like the volume, balance and playing of the sound in the video

Coding

You must have DirectX 9 SDK installed to use the avi playing feature described in this article. You can get this SDK from the Microsoft MSDN site. (Note: It may require an MSDN subscription to get the full SDK, but the redistributable that runs the video is a free download). Once you have the DirectX SDK installed, you can include the Microsoft.DirectX.AudioVideoPlayback assembly as a reference to your project. Just right click on your project References in the Solution Explorer and add the reference as shown below. (If this reference isn't in the .NET assembly list, you probably don't have the DirectX 9 SDK installed):

Figure 2 - Adding the DirectX AudioVideoPlayback Reference

Now you just need to add the using statement in your Form to begin using the Video class:

using Microsoft.DirectX.AudioVideoPlayback;

So now let's take a look at the implementation of the Video Class. The first step is to construct a Video object with the name of the video file which we retrieve from a OpenFile dialog. We then assign the Video.Owner property to the panel inside our winform. Also we resize the video to fit the original dimensions of the panel. Finally we quickly play and pause the video, in order to see the first frame.

/// <summary>
/// opens a video from an avi file
/// and plays the first frame inside the panel
/// </summary>
void OpenVideo()
{
openFileDialog1.InitialDirectory = Application.StartupPath;
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
// open the video
// remember the original dimensions of the panel
int height = videoPanel.Height;
int width = videoPanel.Width;
// dispose of the old video to clean up resources
if (_video != null)
{
_video.Dispose();
}
// open a new video
_video = new Video(openFileDialog1.FileName);
// assign the win form control that will contain the video
_video.Owner = videoPanel;
// resize to fit in the panel
videoPanel.Width = width;
videoPanel.Height = height;
// play the first frame of the video so we can identify it
_video.Play();
_video.Pause();
}
// enable video buttons
ControlLogic();
}

That's really all there is to using the video object. If we want to play the video until the end, we simply call the Play method on the video object .

/// <summary>
/// Plays the video
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void btnPlay_Click(object sender, System.EventArgs e)
{
if (_video != null)
{
_video.Play();
}
}

Conclusion

The Video class in the Microsoft.DirectX.AudioVideoPlayback library is a powerful graphics class with a very simple implementation. Using this class, you can create powerful applications that include your favorite movie clips in the common avi format. I suspect it will play other movie formats as well (such as mpeg), however, I haven't tried it. Good luck with this powerful multimedia tool and using it to see sharp videos.
