Hello,
After making the my first interactive demo I notice that the are too many
IF and too much code for a simple project so I whould like to know
how to make this if in to a " CASE " you know all a case x of .
Well here is the if.
...............................................................
if (X > 280) and (Y > 20) and (X < 320) and (Y < 220)
and (label1.Caption = 'Spot 1 front') then
begin
image1.Picture.LoadFromFile('house\house1r.bmp');
label1.Caption:=('Spot 1 right');
end
else
if (X > 280) and (Y > 20) and (X < 320) and (Y < 220)
and (label1.Caption = 'Spot 1 right') then
begin
image1.Picture.LoadFromFile('house\house1b.bmp');
label1.Caption:=('Spot 1 back');
end
else
if (X > 280) and (Y > 20) and (X < 320) and (Y < 220)
and (label1.Caption = 'Spot 1 back') then
begin
image1.Picture.LoadFromFile('house\house1l.bmp');
label1.Caption:=('Spot 1 left');
end
else
if (X > 280) and (Y > 20) and (X < 320) and (Y < 220)
and (label1.Caption = 'Spot 1 left') then
begin
image1.Picture.LoadFromFile('house\house1f.bmp');
label1.Caption:=('Spot 1 front');
end
...............................................................
If is not possible to make if in to a case the how can a reduce the code?

| You could make one big if for the (X > 280) and (Y > 20) and (X < 320) and (Y < 220) because that's the same for all. if (X > 280) and (Y > 20) and (X < 320) and (Y < 220) then if (label1.Caption = 'Spot 1 front') then begin (...) (23 years ago, 9-May-02, to lugnet.cad)
