请问什么叫模拟鼠标和键盘事件?什么叫捕捉鼠标和键盘事件呢? 我最不明白的是,怎么去模拟鼠标和键盘事件。这样的,要求做成控件形式,不可以去其它程序有影响。那模拟鼠标键盘还有什么呢?接口是怎么的呢。是不是给用户一下 接口,让他选择触发什么键,我就在系统中去触发一下呢?题意有点不懂,请大家指教。谁有代码和例子更为感激!!! 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 ONMOUSEDOWN,ONMOUSEUP,ONMOUSEMOVE,ONKEYDOWN,ONKEYUP,ONKEYPRESS看OBJECT INPECTOR的EVENT就明白了 鼠标和键盘事件就是当点击它们时,window把响应传给应用程序,把这个响应称为消息。扑捉鼠标和键盘事件就是得到这个消息。 看这个吧--------------------------------(转)------------------------------------------鼠标自动点击的例子,模拟鼠标点击procedure TForm1.Button1Click(Sender: TObject);var x,y:integer;beginx:= form1.Left+button2.Left+25;y:= top+button2.Top+27;SetCursorPos(x,y);Mouse_Event(MOUSEEVENTF_LEFTDOWN,X,Y,0,0);Mouse_Event(MOUSEEVENTF_LEFTUP,X,Y,0,0);end;procedure TForm1.Button2Click(Sender: TObject);begin showmessage('fksj');end;*************************************// Set the mouse cursor to position x,y: SetCursorPos(x, y); // Simulate the left mouse button down mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0); mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0); // Simulate the right mouse button down mouse_event(MOUSEEVENTF_RIGHTDOWN, 0, 0, 0, 0); mouse_event(MOUSEEVENTF_RIGHTUP, 0, 0, 0, 0); -----------------------(转)---------------------------------下面的代码是模拟Ctrl+C和Ctrl+V://Ctrl+C: keybd_event(VK_CONTROL, MapVirtualKey(VK_CONTROL, 0), 0, 0); keybd_event(Ord('C'), MapVirtualKey(Ord('C'), 0), 0, 0); keybd_event(Ord('C'), MapVirtualKey(Ord('C'), 0), KEYEVENTF_KEYUP, 0); keybd_event(VK_CONTROL, MapVirtualKey(VK_CONTROL, 0), KEYEVENTF_KEYUP, 0) //Ctrl+V: keybd_event(VK_CONTROL, MapVirtualKey(VK_CONTROL, 0), 0, 0); keybd_event(Ord('V'), MapVirtualKey(Ord('V'), 0), 0, 0); keybd_event(Ord('V'), MapVirtualKey(Ord('V'), 0), KEYEVENTF_KEYUP, 0); keybd_event(VK_CONTROL, MapVirtualKey(VK_CONTROL, 0), KEYEVENTF_KEYUP, 0) **************************按下一个键最好用SendMessage,用sndkey32.pas无疑会增加程序尺寸。组合键(超过两个以上)用sndkey32.pas就显出优势来了。另一种解决方法,下例模拟按下Alt+Down,可参见Delphi SDK的帮助: keybd_event( VK_MENU, MapVirtualKey( VK_MENU, 0 ), 0 , 0 ); // Alt down keybd_event( VK_DOWN, MapVirtualKey( VK_DOWN, 0 ), 0 , 0 ); // down arrow key down keybd_event( VK_DOWN, MapVirtualKey( VK_DOWN, 0 ), KEYEVENTF_KEYUP , 0 ); // down arrow key up keybd_event( VK_MENU, MapVirtualKey( VK_MENU, 0 ), KEYEVENTF_KEYUP , 0 ); // Alt key up 让 WIN95 模拟按了一个按键,例如按下 ENTER或者 TAB 键?PostMessage(Object.Handle, WM_KEYDOWN, VK_TAB, 0);////////////////////////////////unit Unit1;interfaceuses SysUtils, WinTypes, WinProcs, Messages, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls;type TForm1 = class(TForm) Button1: TButton; Button2: TButton; procedure Button1Click(Sender: TObject); procedure Button2Click(Sender: TObject); procedure FormKeyPress(Sender: TObject; var Key: Char); private AppInst: THandle; AppWind: THandle; public { Public declarations } end;var Form1: TForm1;implementation{$R *.DFM}uses ShellAPI; procedure SendShift(H: HWnd; Down: Boolean);var vKey, ScanCode, wParam: Word; lParam: longint;begin vKey:= $10; ScanCode:= MapVirtualKey(vKey, 0); wParam:= vKey or ScanCode shl 8; lParam:= longint(ScanCode) shl 16 or 1; if not(Down) then lParam:= lParam or $C0000000; SendMessage(H, WM_KEYDOWN, vKey, lParam);end;procedure SendCtrl(H: HWnd; Down: Boolean);var vKey, ScanCode, wParam: Word; lParam: longint;begin vKey:= $11; ScanCode:= MapVirtualKey(vKey, 0); wParam:= vKey or ScanCode shl 8; lParam:= longint(ScanCode) shl 16 or 1; if not(Down) then lParam:= lParam or $C0000000; SendMessage(H, WM_KEYDOWN, vKey, lParam);end;procedure SendKey(H: Hwnd; Key: char);var vKey, ScanCode, wParam: Word; lParam, ConvKey: longint; Shift, Ctrl: boolean;begin ConvKey:= OemKeyScan(ord(Key)); Shift:= (ConvKey and $00020000) <> 0; Ctrl:= (ConvKey and $00040000) <> 0; ScanCode:= ConvKey and $000000FF or $FF00; vKey:= ord(Key); wParam:= vKey; lParam:= longint(ScanCode) shl 16 or 1; if Shift then SendShift(H, true); if Ctrl then SendCtrl(H, true); SendMessage(H, WM_KEYDOWN, vKey, lParam); SendMessage(H, WM_CHAR, vKey, lParam); lParam:= lParam or $C0000000; SendMessage(H, WM_KEYUP, vKey, lParam); if Shift then SendShift(H, false); if Ctrl then SendCtrl(H, false);end;function EnumFunc(Handle: HWnd; TF: TForm1): Bool; Far;begin TF.AppWind:= 0; if GetWindowWord(Handle, GWW_HINSTANCE) = TF.AppInst then TF.AppWind:= Handle; result:= (TF.AppWind = 0);end;procedure TForm1.Button1Click(Sender: TObject);var Text: Array[0..255] of char;begin AppInst:= ShellExecute(Handle, 'open', 'notepad.exe', nil, '', SW_NORMAL); EnumWindows(@EnumFunc, longint(self)); AppWind:= GetWindow(AppWind, GW_CHILD);end;procedure TForm1.Button2Click(Sender: TObject);begin SendKey(AppWind, 'T'); SendKey(AppWind, 'e'); SendKey(AppWind, 's'); SendKey(AppWind, 't');end;procedure TForm1.FormKeyPress(Sender: TObject; var Key: Char);begin if AppWind <> 0 then SendKey(AppWind, Key);end;end.///////////////////////////////////////////////////////////////////////Ah,这个嘛......正好在《DELPHI新闻组学习笔记》上看到一篇:How to send [Alt]+[Down]?--------------发出一个Alt+Down 组合键 Re: Use the keybd_event API function to fake keyboard events.
