引言: 您上面的是clx用法,对于windows平台一般用vcl的 function FindControl(Handle: HWnd): TWinControl; 可以返回指定handle的对象！ 用法如下： var mycon:twincontrol; begin mycon:=FindControl(handle); if mycon<>nil then showmessage(mycon.Name); end; 發表人 - sos_admin 於 2003/08/29 14:07:50

var
   mycon:twincontrol;  又出現看不懂的地方了
begin
   mycon:=FindControl(handle);
   if mycon<>nil then
      showmessage(mycon.Name);
end;

引言: TWinControl is the base class for all controls that are wrappers for Microsoft Windows screen objectss. 上面是一个根据handle找元件的例子
