Look for a Bitmap/DTM tut..
SCAR Code:
program Click Button;
var x,y: Integer;
var Button: Integer;
begin //Click Button
Button := DTMFromString('78DA63E4666060D8C2C8800CAE5EBD0AA661A' +
'28C1C4062330135AC40623B11E6EC22A006E49E9D04D4680389AD' +
'04D46812E11E0D22DC03B26B070135C244980352B309BF1A0025B' +
'E246A');
if (FindDTM(Button,x,y,0, 0, 1000, 1000)) then
begin
MoveMouseSmooth(x,y);
ClickMouse(x,y,true);
Writeln ('Clicked Button')
Wait (1000);
end;
end.
Something like this, now you only have to make a DTM of the button you want
