Hi Aaron,
I have been facing some strange problem with File streams. When I update (I mean write
some characters to the middle of the file
stream), it appears to me that the rest of the contents, that originally were in the
filestream, are lost.
I had to write the file contents into a temporary file and then write them back to the
file.
Do you have any idea or is this the way it is suppose to work?
I will be very thank full to your help.
Thank you,
Chida
