hi to all,

i have an app (not from me) which should
be used automatically when it is running.
This app contains one editfield, some checkboxes
and four buttons.
i want to write an app in D3, which puts in the
editfield a certain text and then presses the OK-button.
how i can get the handle of this editfield and the
ok-button ?
i know how to get the handle of this app (by findwindow).
if i would have the handle of the editfield:
the rest would be simple (transfer the text by postmessage
to the editfield).
and how can i get the handle of the ok-button
(there are four buttons in the app) ?

thanks
titz

If you don't know the EditField's ClassName and Window name,Use WinSight32.exe to get that information. to get the button's handle use same method.

procedure TForm1.Button1Click(Sender: TObject);
var
  H1,H2:THandle;
begin
  H1:=FindWindow(nil,'Form1');
  H2:=FindWindowEx(H1,0,'TEdit','Edit1');
  SendMessage(H2,WM_SETTEXT,0,Integer(PChar('shenqw'))); //Must use Sendmessage.
end;

hi shenqw,

this works good for the editfield, but not for the button.
but do you know what message i have to send for the button ?

or otherwise: when i press the <return>-key is the same as clicking at the button.
how can i simulate this ?
the following does not work:
sendmessage(h2,wm_settext,0,vk_return);

thanks
