[笨嘴拙舌WINDOWS]实践检验之按键精灵[Delphi]
【笨嘴拙舌WINDOWS】实践检验之按键精灵【Delphi】
通过记录键盘和鼠标位置和输入信息，然后模拟发送，就能够创建一个按键精灵！
主要代码如下：
1 library KeyBoardHook; 2 3 { Important note about DLL memory management: ShareMem must be the 4 first unit in your library's USES clause AND your project's (select 5 Project-View Source) USES clause if your DLL exports any procedures or 6 functions that pass strings as parameters or function results. This 7 applies to all strings passed to and from your DLL--even those that 8 are nested in records and classes. ShareMem is the interface unit to 9 the BORLNDMM.DLL shared memory manager, which must be deployed along10 with your DLL. To avoid using BORLNDMM.DLL, pass string information11 using PChar or ShortString parameters. }12 13 uses14 SysUtils,15 Classes,16 Windows,17 Messages;18 19 type20 TCallBackFun=procedure(info:PChar);21 TKeyBoardHook=record22 isrun:Bool;23 hook:HHook;24 callBackFun:TCallBackFun;25 end;26 27 var28 myKeyBoardHook:TKeyBoardHook;29 {$R *.res}30 31 function GetKeyBoardInfo(code:Integer;wp:WPARAM;lp:LPARAM):LRESULT;stdcall;32 var33 info:string;34 begin35 if code
以上是创建一个全局钩子函数的Dll来记录按键信息
library Mousehook;{ Important note about DLL memory management: ShareMem must be the first unit in your library's USES clause AND your project's (select Project-View Source) USES clause if your DLL exports any procedures or functions that pass strings as parameters or function results. This applies to all strings passed to and from your DLL--even those that are nested in records and classes. ShareMem is the interface unit to the BORLNDMM.DLL shared memory manager, which must be deployed along with your DLL. To avoid using BORLNDMM.DLL, pass string information using PChar or ShortString parameters. }uses SysUtils, Classes, Windows, Messages, ShellAPI; type TCallbackFun=procedure(info:pchar); TMouseHook=record isrun:Bool; hook:HHook; callbackFun:TCallbackFun; end;var myMouseHook:TMouseHook;{$R *.res}//1.定义自定义的HOOK函数，函数必须和需要HOOK的钩子类型保持同样的参数列表function GetHookInfo(code:Integer;wp:WPARAM;lp:LPARAM):LResult;stdcall;var info:String;begin if code
以上是捕获鼠标消息的全局钩子DLL
使用一个新的线程来模拟发送消息
procedure TPlayThread.Execute;var directive:string; i:integer; ForgroundForm:TForm; procedure ExecuteDir(directive:string); var tempList:TStringList; Wp,Lp:integer; wmtype:String; focusControl:string; duration:Cardinal; winCtl:TWinControl; tempHandle,focusHandle:THandle; classname:String; mousPoint:TPOINT; procedure findFocus; var temp:TWinControl; finded:Boolean; begin if ((wmtype='WM_MOUSEMOVE') or (wmtype='WM_NCMouseMove')) then Exit; winCtl:=TWinControl(ForgroundForm.FindChildControl(focusControl)); if winCtlnil then begin focusHandle:= winCtl.Handle; AttachThreadInput(GetWindowThreadProcessId(ForgroundForm.Handle,nil),Self.ThreadID,True); Ferrorinfo:=SysErrorMessage(GetLastError); winCtl.SetFocus; AttachThreadInput(GetWindowThreadProcessId(ForgroundForm.Handle,nil),Self.ThreadID,False); Ferrorinfo:=SysErrorMessage(GetLastError); Exit; end; temp:=nil; finded:=False; while not finded do begin GetCursorPos(mousPoint); tempHandle := WindowFromPoint(mousPoint); if tempHandle =0 then begin Sleep(0); Continue; end; temp:=FindControl(tempHandle); if temp=nil then begin Sleep(0); Continue; end; if (temp.Name = focusControl) or (classname=temp.ClassName) then finded:=True; end; focusHandle := temp.Handle; AttachThreadInput(GetWindowThreadProcessId(ForgroundForm.Handle,nil),Self.ThreadID,True); Ferrorinfo:=SysErrorMessage(GetLastError); temp.SetFocus; AttachThreadInput(GetWindowThreadProcessId(ForgroundForm.Handle,nil),Self.ThreadID,False); Ferrorinfo:=SysErrorMessage(GetLastError); end; begin tempList:=TStringList.Create; try tempList.CommaText:=directive; tempList.Delimiter:=','; wmtype:=tempList[0]; focusHandle:=0; Wp:=StrToIntDef(tempList[1],0); //wParam Lp:=StrToIntDef(tempList[2],0); //Lparam duration:= StrToIntDef(tempList[3],0); if (duration=0) and (wmtype='WM_NCMouseMove') then Exit; //小于线程调度时间片的话就不延时---以免 sleep(0)直接放弃时间进入内核态 if (wmtype='') or (tempList.Count
