retrieving a zipped file from a database

[7seven7]

Once i zipped my file a simple .xls spread sheet i write it to a database ... evoking the toArray() method of the memory stream, however now trying to recover this zipped file it doesn't display the zip within. My question is this how will i get the zipped file to show

My guess is that there's some kind of mismatch between the way you're serializing and de-serializing the data.
Are you able to post a code sample that demonstrates how you are saving the file to the database and how you are retrieving it?
