Hello,
Being a Newby , I am using delphi 5 (under XP) and tried the following

in Unit M:
Graphic methods (calculating values and using canvas.Moveto, canvas.Lineto,
canvas.Pixel etc)

in Unit N:
1.procedure: calling all functions within one function with name "do_it"
2. procedure: for image on screen : calling function "do_it" in the
following way:

with paintbox.canvas do
begin
do-it
end;

planning to do in the same way
3. procedure: for printer: calling function "do_it" in the following way:
with printer do
begin
// printer stuff ? ? how adapt to printer
do_it
end;

even the 2. procedure doesn't work , but if I replace " canvas" by
FormN.paintbox.canvas in each method it works
He accepts all commands of the type canvas.method but there is nothing on
the screen.....

Is there a simple bug somewhere or isn't it possible to make him applying
all canvas.methods to the paintbox in this way?
How can I do it?

Thanks
