如题所示：<br>比如下面就是回调函数，，中间应该怎么写才能实现这个目的。<br>function TestHookProc(Code:Integer;WParam:WParam;Msg:LongInt):LRESULT;stdcall;<br>begin<br>end;<br> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 谢先拉！

钩子挂在哪里？系统中？消息队列中？

问题已经解决：<br>如下：<br>function TestHookProc(Code:Integer;WParam:WParam;Msg:LongInt):LRESULT;stdcall;<br>begin<br>if Code=HC_ACTION then<br>begin<br>PMsg(Msg)^.message:=0;<br>end;<br>Result:=CallNextHookEx(HookHandle,Code,WParam,longint(@Msg));<br>end;<br>end;
