Hello,
I have some question...
1. what is the differences between this code
procedure SetCaption(_val:string);
procedure SetCaption(const _val:string);
In [ ...(_val:string)] you may modify the value of _val but it's not
visible to the outside world (the calling routine). A copy of _val is
handed to SetCaption
In [ ...(const _val:string)] you may not modify the value of _val
because the compiler will not allow it. This is slightly faster, because
not a copy but the reference to _val is handed to the routine.
2. I create a spooling program but It's work very slow.
Now I spool an image but It's size so big 60Mb,... I want to change
imagedata to rawdata.... but I don't know how it's works... (I'm not
print an image but textfile).
Actually I am not able to understand what you mean.
From where to what do you 'spool' the image?
What exactly do you mean by spool?
What exactly do you mean by 'imagedate to rawdata'?
