Hi,
I have a problem and don't know how to solve it.
I am storing files (jpg, etc) in a table as binaries (image data type)
and would like to be able to show progress bar when I am loading it
from database.
But to do that, I need somehow to get the size of that file that is
stored in database (as image data type). Unfortunatelly my table does
not have a 'file_size' column from where I could get the size of image
and I am not in position to change that.
So far I am reading or writing to databasse successfully using
FileStream or BinaryREader/Writer (in VB.NET), so that is not the
problem.
Does anybody know how can I get the size of an file stored in
database?
Any help will be greatelly appreciatedThis is a multi-part message in MIME format.
