HELP: Speed of dealing with huge amounts of data in VB
Hi,
I am using Visual Basic 3.0 for Windows to design a user interface
for application of EEG signals.
I got a lot problems of speed. First, it is slow to read the data
from the disk file; second, it is even slower to display them on the screen.
The signal involved is huge, about 21 channels and 20 minutes long.
At one single time, I want to display 16 s of signal which consists of
1024 samples. Then I'd like to have various paging facilities to move
the data around.
At the moment, I am using normal binary access to read data from disk
files and then using line statement to display them. But they are really slow
indeed. Could anyone there tell me if there are better ways of doing
this job.
Thanks very much in advance for your help.
