SDK2000的DLL實現方法

 對SDK2000視頻開發包的DLL方式操作

 

將已經翻譯的VideoSDK2000U.pas單元放入改工程文件夾中 相關引用操作完整代碼如下：

---------------------------------------

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, OleCtrls, SDK_2000Lib_TLB;

type
  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    Button3: TButton;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure Button3Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}
uses unit2,VideoSDK2000U;

 

// [打開]功能代碼

procedure TForm1.Button1Click(Sender: TObject);
var
  arect:TRect;
begin
  Form2:=TForm2.Create(Form1);
  arect.Top :=15;
  arect.Bottom :=350;
  arect.Left :=20;
  arect.Right :=400;
  VideoSDK2000U.DSStream_Initialize() ;
  Form2.Show ;
  VideoSDK2000U.DSStream_ConnectDevice(0,true,Form2.Handle ) ;
  VideoSDK2000U.DSStream_SetWindowPos(0,arect);
end;

 

// [斷開]功能代碼

procedure TForm1.Button2Click(Sender: TObject);
begin
  VideoSDK2000U.DSStream_Uninitialize();
  Form2.Close ;
end;

 

// [設置]功能代碼

procedure TForm1.Button3Click(Sender: TObject);
begin
  VideoSDK2000U.DSStream_DisplayPropertyDialogs(0,,Form1.Handle ,nil);
end;

end.
