用Delphi編程模擬鼠標(biāo)操作

下面以鼠標(biāo)左鍵單擊為例來說明如何模擬鼠標(biāo)操作：
    procedure TForm1.btnLClickClick(Sender: TObject);
    begin
    SetCursorPos(10,10);
    mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);
    mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
    end;
    首先需要通過SetCursorPos函數(shù)來設(shè)置需要單擊的坐標(biāo)。然后通過mouse_event (MOUSEEVENTF_LEFTDOWN,0,0,0,0)語句在(10,10)坐標(biāo)處按下鼠標(biāo)左鍵。最后不要忘了通過mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0)語句釋放鼠標(biāo)左鍵。
    雙擊的操作可以通過兩個連續(xù)的單擊來實現(xiàn)；鼠標(biāo)移動的操作可以通過指定mouse_event 函數(shù)的第1個參數(shù)MOUSEEVENTF_MOVE，第2個和第3個參數(shù)為左邊來實現(xiàn)；右鍵單擊和左鍵單擊的原理一致，只不過mouse_event函數(shù)中的參數(shù)分別替換為MOUSEEVENTF_RIGHTDOWN和MOUSEEVENTF_RIGHTUP。
    程序代碼如下：
    unit Unit1;
    interface
    uses
    Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
    Dialogs, StdCtrls;
    type
    TForm1 = class(TForm)
    btnMove: TButton;
    btnLClick: TButton;
    btnLDClick: TButton;
    btnRClick: TButton;
    procedure btnMoveClick(Sender: TObject);
    procedure btnLClickClick(Sender: TObject);
    procedure btnLDClickClick(Sender: TObject);
    procedure btnRClickClick(Sender: TObject);
    private
    { Private declarations }
    public
    { Public declarations }
    end;
    var
    Form1: TForm1;
    implementation
    {$R *.dfm}
    procedure TForm1.btnMoveClick(Sender: TObject);
    begin
    mouse_event(MOUSEEVENTF_MOVE,100,100,0,0);
    end;
    procedure TForm1.btnLClickClick(Sender: TObject);
    begin
    SetCursorPos(10,10);
    mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);
    mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
    end;
    procedure TForm1.btnLDClickClick(Sender: TObject);
    begin
    SetCursorPos(200,200);
    mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);
    mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
    mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);
    mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
    end;
    procedure TForm1.btnRClickClick(Sender: TObject);
    begin
    SetCursorPos(200,200);
    mouse_event(MOUSEEVENTF_RIGHTDOWN,0,0,0,0);
    mouse_event(MOUSEEVENTF_RIGHTUP,0,0,0,0);
    end;
    end.
