当年我Http://rbsky.myetang.com/SuperEx.exe中实现从屏幕当前鼠标位置取得对象类名称、句柄、文本的代码:
procedure TMain.FowTimTimer(Sender: TObject);
var poss:TPoint;
ic:Hdc;
Bmp:TbitMap;
Hands: HWND;
Buf: array[0..129] of Char;

itmp,iwidth,iheight:integer;
sword,sline:string;
begin
GetCursorPos(Poss);
with FmFol do
begin
if (poss.x <> tag-10) or (poss.y<>FowTim.Tag-10) then left:=screen.Width
else
begin
Hands := WindowFromPoint(Poss);
if (left=tag) or (hands=handle) then exit;
// if (left=tag) or (hands=handle) or (hands=main.handle) then exit;
stmp:=TStringList.create;
stmp.Add('句柄: '+IntToStr(Hands));
GetClassName(Hands, Buf, 128);
stmp.Add ('类名: '+Buf);
itmp:=GetParent(Hands);
while itmp>0 do
begin
{if (itmp=application.Handle) or (itmp=main.handle) then
begin
stmp.Free;
exit;
end }
// else

if buf<>'' then stmp.Add (inttostr(stmp.Count-1)+'级父类: '+Buf);
itmp:=GetParent(itmp);
// end;
end;
SendMessage(Hands, WM_GETTEXT, 128, Integer(@Buf));
sword:='字符: '+buf;
if length(sword)>132 then sword:=sword+'....';

这句是取得对象的字符
