read Binary data from database. I will told you what I did :

first I declear an array byte and I cast the value in the database to byte
after that I use memory stream then I read the value by using method
FromMemoryStream that In Image class to finally but my pic In PictuerBox.

My code is lookslike the following:

Dim pic() as Byte=Ctype(myreader.getvalue(1),Byte())

myreader is the data reder that I used to read my data from database.

dim ms as new memorystream(pic)

with PictureBox1
End with
But the probelm is I getthe length of pic() 0 thatmena there is no value.

I tried Alot of method and see alot Of Articals In reading blob or Binary
data from database but non were useful
