Hi Ton,
Instead of using 'get url' to read the large file, use the open file /
read file / close file commands. (The 'seek' command might also be
useful.) That way you don't have to pull the entire file into memory at
one time. Then you will have better control over the user's experience.
I would go into more detail but I have to run...

Hi gang... I need some help...
A user selects a PDF file, I need to know what colors are in this PDF
file.
So far no good, I can read the data and filter out the unwanted lines.
But this becomes a problem when the PDF file is 50 Mb or bigger...
At this point I use:
put "file:" & vPDFpath into vURL
put url vURL into vColors1
put url vURL into vColors2
filter vColors1 with "*/Separation*"
replace "#20" with space in vColors1
filter vColors2 with "*/DeviceN*"
replace "#20" with space in vColors2
replace "]" with "" in vColors2
put vColors1 & vColors2 into vColors
This way I get the lines containing the PDF colors, which I filter
and use.
On normal PDF's this happens on the fly, no delay at all...
But one of my clients now sent me a 200 Mb PDF... And you can guess
the problem: The file is loaded into memory twice, taking up more
then 400 Mb of memory, just to get 3 or 4 lines of data... It's
ssssllloooooowwwwwwwwww....
Any ideas on how to do this faster?
Warm regards,
Ton Kuypers
