Anyone got any scripts lying around that can:

Show the speed in which a file is being downloaded.

eg. using vdsipp.dll to download the file, retreiving the transfer bytes,

How to you calculate the KB/Sec using the transfer bytes and time?

Anyone any scripts, code etc

Thanks

Nathan

Hmmm... how about his one:

Code:

#define function, internet

%%TransferredBytes_1 = @internet(http, transferredbytes, 1)
wait 1
%%TransferredBytes_2 = @internet(http, transferredbytes, 1)

%%TransferredBytes = @diff(%%TransferredBytes_2, %%TransferredBytes_1)
#--- %%TransferredBytes now holds the number of bytes tranferred in one second
%%Speed = @fdiv(%%TransferredBytes, 1000)
info Your download speed is %%Speed Kb/Sec


Regards Smile,
Vic

This way you can calculate the average speed from the beginning of the download:

Code:
#define function,internet

rem Calculate the time in seconds...
%%Starttime = @sum(@prod(@datetime(hh),3600),@prod(@datetime(nn),60),@datetime(ss))

rem Just wait a while...
wait 1

rem Calculate the time in seconds again...
%%Endtime = @sum(@prod(@datetime(hh),3600),@prod(@datetime(nn),60),@datetime(ss))

rem To make kB from bytes, you should divide it with 1024...
%%TransferredKiloBytes = @div(@internet(http, transferredbytes, 1),1024)

rem And the speed is the number of kB / the total time...
%%Speed = @fdiv(%%TransferredKiloBytes,@diff(%%Endtime,%%Starttime))

info The speed is around %%Speed kB/sec...

Oops Embarassed

I made the example in about two minutes and I didn't thought about that one. I should have known Wink
