The problem i am having is with trying to save a portion of an image on the hard drive, with a different name ( in other words, i'm cropping an image and wanting to save that part somewhere).

Aug 29, 2010I have a mySQL table(IMP_SCANS) holding the file, it's name and size for every document:

doc_date date
I managed to insert a file to the table. Now I need to save the file to disk.
So I have the code:

Dim cmd As New MySqlCommand

I all works fine up to the line: myData.GetBytes(myData.GetOrdinal("scan_1"), 0, rawData, 0, filesize) Where it says "Object reference not set to an instance of an object". I cannot figure out why I receive this error.
