my situation:

At home I run Delphi 4 C/S, at school Delphi 3 C/S.

my problem:
When I make a form at home and then load it at school and put a button besides the one I put on at home, it appears much smaller. also the Formx.PixelsPerInch is different. What is the solution for having the same comonentsizes for my project whether or not I work at home or at school?

Thanks

The solution is at the most simple.

If you like to act upon the screen resolution, you will have to resize every visual control after the Forms OnResize event, defining lenghts in percent.

If you would like to act upon the froms Pizels per inch property, you just need to do this:

procedure TForm1.FormCreate(Sender: TObject);
begin
  Scaled:= True;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  ShowMessage('Pixels per Inch:' +IntToStr(PixelsPerInch));
end;

This doesnt really do what I want, but I guess this is the only way, I now have all Forms to Scaled := False.

Is it the size of button or form that gives the actual problem when you are dragging a component to the form?

If so, have you tried checking the options on the grid? (Select Tools->Environment Options->Preferences)
